  2. 2. READ ME FIRST Welcome to Take Control of Users & Accounts in Leopard, version 1.0. This book tells you everything you need to know about users and accounts for the users of a single Macintosh running Leopard, how to set them up, configure them, and manage them. This book was written by Kirk McElhearn, edited by Tonya Engst, and published by TidBITS Publishing Inc. Copyright © 2007 Kirk McElhearn. All rights reserved. The price of this ebook is $10.

If you own only the print version of the book, contact us at tc-comments@tidbits.com to obtain the ebook. In reading this book, you may get stuck if you don’t know certain basic facts or if you don’t understand Take Control syntax for things like working with menus or finding items in the Finder. Please note the following: • Path syntax: I occasionally use a path to show the location of a file or folder in your file system. Path text is formatted in bold type. For example, Leopard stores most utilities, such as Disk Utility, in the Utilities folder. The path to Disk Utility is: /Applications/ Utilities/Disk Utility. The slash at the start of the path tells you to start from the root level of the disk. You will also encounter paths that begin with ~ (tilde), which is a shortcut for any user’s home directory. For example, if a person with the user name joe wants to install fonts that only he can access, he would install them in his ~/Library/ Fonts folder, which is just another way of writing /Users/joe/ Library/Fonts.

  3. 3. • Menus: When I describe choosing a command from a menu in the menu bar, I use an abbreviated description. For example, the abbreviated description for the menu command that displays information about a file is “File > Get Info.” • Finding preference panes: I sometimes refer to Mac OS X preferences that you may want to adjust. To change these system- wide settings, open System Preferences by clicking its icon in the Dock or choosing System Preferences from the  menu. You access a particular preference pane by way of its icon, or the View menu. For example, to see “the Accounts preference pane,” you would launch System Preferences and then click the Accounts icon or choose View > Accounts. • Panes and sections: The content in a System Preferences pane can be dynamic. When I describe the area of a pane that has changed after a click to a blue button (sometimes called a “tab”) at the top of the pane, I call that content area a “section.” Page 3 This is a free sample of “Take Control of Users & Accounts in Leopard.” Click here to buy the full 88-page ebook for only $10!
  4. 4. INTRODUCTION Apple has done an excellent job of hiding many of Mac OS X’s Unix underpinnings, so Unix-related features such as preemptive multi- tasking make the Mac work better than ever before, without drawing attention to themselves. But other aspects of that Unix foundation do affect the way we work in important and noticeable ways; for example, Unix brings a full multi-user operating system to OS X, which means that each person who wishes to use the Mac must use it while logged into an account. This book goes much further than just telling you how to set up and configure user accounts. I cover the different types of accounts, how to limit the capabilities of certain accounts, and what you need to know about Fast User Switching. I also explain why you should have at least two accounts even if no one else uses your Mac, and give you specific steps for using an extra account to isolate the cause of problems your Mac might experience. In addition, Mac OS X 10.5 Leopard has reinforced the Parental Control features that were present in Tiger. In 10.4, you could apply some limitations to user accounts, but in 10.5, not only are there many more limitations and controls, but these features have been split out into their own preference pane. By the end of this book you’ll be able to take control of all the Leopard accounts of the users working at your Mac—whether you have one or dozens—and work more efficiently with Leopard.

  5. 5. WORKING WITH ACCOUNTS QUICK START User accounts affect almost everything you do under Mac OS X. You must have at least one account, and, if you need to create additional accounts, you can do so easily. Here’s an overview of how you can use this book to work with accounts in Leopard: Learn about accounts: • Learn what user accounts are, and why you need them. Read About User Accounts (p. 7). • Discover what has changed with accounts from Tiger to Leopard. See What’s New in Leopard (p. 9). • Find out about the many Types of Accounts (p. 11), including the Guest Account (p. 19), which is new in Leopard. • Learn strategies for setting up accounts for situations that you may not have previously considered, such as for troubleshooting or visitors. Read Choose an Account Strategy (p. 21). Create and delete accounts: • Set up and configure a new account. See Set Up an Account (p. 26). • Set Parental Controls for an account (p. 35). • Delete an Account (p. 32), if you like. • Do you consider yourself an advanced power user? You may be interested in the new Advanced User Account Options (p. 30), or wish to Enable or Disable the Root Account (p. 33). Work with accounts: • Log in and out of an account, plus customize options to simplify or secure the login process. See Log In to and Out of Accounts (p. 50). • Use Fast User Switching to share your Mac more efficiently (p. 54). • Make certain programs launch (or not launch) on login; read Manage Login and Startup Items (p. 57).

  6. 6. • Use your knowledge of user accounts to perform basic trouble- shooting. See Troubleshoot Startup and Login Items (p. 62) and Troubleshoot Preference Files (p. 66). Share files among users: • Choose a method for sharing files among users on the same Mac, and set one up. See Share Files among Users (p. 69). • Share media, including music and photos. Find out how in Appendix A: Share Digital Media Files (p. 79). Page 6 This is a free sample of “Take Control of Users & Accounts in Leopard.” Click here to buy the full 88-page ebook for only $10!
  7. 7. ABOUT USER ACCOUNTS User accounts are at the heart of any Unix-based operating system, including Mac OS X. The entire system relies on this concept, so hav- ing a basic understanding of what accounts are and why you need them will help you better comprehend and use Mac OS X. Since Unix-based operating systems rely on the concepts of permis- sions and ownership, each file, folder, and application must belong to a specific user. For this to be the case, users must be declared and identified; hence the idea of creating unique accounts for each user, much as every customer of a bank has a private account that no one else can access. When you set up or receive an account on Mac OS X, you become a user of that computer, and you are assigned a home folder (the folder with your short user name and the house icon). Your home folder holds your personal files and a number of sub-folders that help you further organize your files. Because your files belong to you, other users cannot access files in your home folder, or in any sub-folders of your home folder. This is also true in the other direction: you cannot access files in other users’ folders. The only exceptions are the Public folder and the Drop Box folder: to help users on the same Mac, or remote users with the appropriate access, share files, each home folder contains a Public folder, from which any user can copy files, and this folder contains a Drop Box folder, into which any user can copy files. In addition to segregating files among users, Unix-based operating systems prohibit standard users from accessing, changing, or deleting essential system files. This prevents standard users from damaging the operating system. Administrators, however, can access all files on a computer. I talk more about this distinction later, in Types of Accounts.

  8. 8. TYPES OF ACCOUNTS Leopard offers three normal types of accounts that you would assign to regular users of your Macintosh: administrator accounts, standard accounts, and managed accounts. One special instance of a standard account, the Guest account, is always visible in the Accounts prefer- ence pane; this account can be used for friends or relatives who want to use your Mac temporarily. Another account type, Sharing Only, is generally intended for people who need to access files stored on your Macintosh for one reason or another, but who connect to your Mac through a network in order to share files. A special type of account, called root, is not accessible from the Accounts preference pane. And, new in Leopard, there’s the Group account, which I discuss briefly ahead in the note About Sharing Only Accounts and Groups. NOTE Technically speaking, managed accounts are merely a variant of standard accounts, but I follow the example of the Accounts preference pane, which uses both terms in its interface. You can see the types of accounts set up on your Macintosh by view- ing the Accounts pane in System Preferences, as shown in Figure 1. (To open System Preferences, choose it from the  menu or click its icon in the Dock.) FIGURE 1 A quick look at the left side of the Accounts pane in System Preferences reveals which accounts are set up on the Macintosh. You can see the user name for each account and which type of account it is: admin, standard, or managed. The Guest account shows that it is enabled for both login and sharing.

  9. 9. CHOOSE AN ACCOUNT STRATEGY The number of accounts you set up depends not only on how many users you have, but how you want to work with your Mac. In this section, I look at a few different scenarios and make recommend- ations for each one. No matter which scenario best matches your needs, you may also wish to set up the Guest Account. Single User Mac Even if you’re the only person who uses your Macintosh, I suggest that you create one or two additional accounts for security and troubleshooting. Set up a standard account for everyday work If you work alone on your Macintosh, consider setting up a standard account that you’ll use under almost all circumstances. This may seem strange, since only administrators can install software or change certain preferences. But if you need to do these tasks, you always have the option of authenticating as an administrator by entering the user name and password of an administrator account, even while you are logged into your standard account. This technique provides extra peace of mind, since it’s almost impossible to damage your system as a standard user if you work like this (although if you authenticate as an administrator you have the added power to screw things up). I think that the peace of mind is more important than the potential annoyances, such as an increased number of authentication requests and having to log in to your administrator account to create folders outside of your home folder. However, if you install a lot of software, or make many changes that require an administrator password, these alerts may lose meaning and you may be tempted to always authenticate, without thinking, when you see them. Set up a troubleshooting account Whether or not you decide to use a standard account for everyday work, you may wish to create a special administrator account for use when solving problems that go beyond the simple troubleshooting you can do by logging in with the Guest account. If something goes wrong with your everyday account, you can log in with the trouble- shooting account to see if the problem persists, and you’ll be able to Page 21 This is a free sample of “Take Control of Users & Accounts in Leopard.” Click here to buy the full 88-page ebook for only $10!
  10. 10. CREATE AND DELETE ACCOUNTS If you’ve read this far, you’ve learned about the different types of accounts (see Types of Accounts, earlier) and you’ve seen my recom- mendations for setting up accounts on your Mac, so you’re in good shape for creating additional accounts and for deleting unnecessary accounts. You’ll already have created one account—an administrator account—when you installed Mac OS X. From that account, you have the power to create as many accounts as you want, and manage them as you see fit. Set Up an Account Follow these steps to create an account: 1. In System Preferences, click the Accounts icon to open the Accounts preference pane. (To open System Preferences, choose it from the  menu or from the Dock.) 2. Then, at the lower left, click the lock icon. When asked, enter your administrator’s user name and password to authenticate. 3. Click the button beneath the account list. A dialog appears, with the insertion point in the Name field. 4. Choose a type of account from the New Account pop-up menu at the top of this dialog. You can choose an Administrator, Standard, Managed with Parental Controls, Sharing Only, or Group account. (You can also change any account, except for a Guest or Sharing Only account, to an administrator account at any time by clicking that account, then checking Allow User to Administer This Computer.) 5. Enter a name for your user. The Name field holds the user’s long name, or full name. (The user’s long name is his real name; the short name is used for the name of his home folder, and need not relate to the long name.)

  11. 11. SET PARENTAL CONTROLS While Tiger had parental controls, they were part of the Accounts preference pane. Leopard has split these functions into their own preference pane, called Parental Controls. You can enable and configure parental controls at any time, for any account. You can also change these limitations as needed: for example, if a certain user needs access to an application you have blocked, or if you want to change the limitations applied to your Guest account. To set or change parental controls, click the Parental Controls icon in System Preferences. You’ll see a list of accounts (Figure 5) to which you can apply parental controls. FIGURE 5 The Parental Controls preference pane shows which accounts you can configure.

  12. 12. LOG IN TO AND OUT OF ACCOUNTS If you’ve used Mac OS X at all, it’s a good bet that you already know the basics of logging in to and logging out of your account. But there are some things you should know about logging in, logging out, and switching users that can make your Mac easier to use. Log In to Your Account Normally When your Mac starts up, you first see a dark gray Apple logo on a gray background with a gear beneath it. The gear turns a few times, then a blue background appears. After another few seconds (unless you have automatic login turned on; see Bypass the Login Window), the Mac displays the login window: • Default login window: By default, the login window lists all the users who have accounts on your Mac, with their pictures followed by their full names, as well as Guest, if you have activated the Guest account. To log in to your account, click your name, and the login window changes to show a Password field. Enter your pass- word, and then click Log In. To log in to the Guest account, click its icon; you don’t need to enter a password. • Custom login window: If you customize the login window to display only a Name and Password field (see Customize the Login Window, next page), you must enter your user name (either your long user name or your short name) and your password, and then click Log In. Or, to log in to the Guest account, just enter Guest Account in the Name field. If you make a mistake typing your password, the login window moves back and forth horizontally—as if it were shaking its head “no.” Re- type your password; you may have pressed a wrong key. Also, check if your keyboard’s Caps Lock key is toggled on; if it is, the Password field will show the Caps Lock symbol, an up-pointing arrow over a horizontal line, at its far right. Once you log in using either of these methods, any login items you set in the Accounts preference pane activate or open. (See later, Manage Login and Startup Items, for more on setting these.) After a few seconds (if you have many login items this can take a minute or more) you see your Desktop, and you can start working.

  13. 13. FAST USER SWITCHING Mac OS X allows you to switch from one user account to another without first logging out of the first account. You can keep applica- tions and documents open in the first account, switch to another account and work in it, then switch back. Fast User Switching is great for people who share a Mac. Say you’re working on your Mac and your spouse or child simply has to check his email. Rather than log out and shut down your applications, you can switch to his account quickly, he can check his email, and then you can switch back to your account and pick up right where you left off. You can also switch to and from the Guest account without logging out from that account. But since leaving applications open in non-active accounts uses some memory, users of professional applications, such as memory-hungry graphics or video programs, may find it impractical. Warning! Make sure you save any files you’re working on before switching to another account. An administrator could shut down the Mac without returning to your account and saving them, or the Mac could crash while active in the other account. When you turn on Fast User Switching, a User menu appears at the far right of your menu bar, to the left of the Spotlight icon. This menu offers commands for switching to other user accounts or displaying the login window. Turn On Fast User Switching To enable Fast User Switching, open the Accounts preference pane, click the Login Options button (at the lower left), and check the Enable Fast User Switching checkbox. Then, choose how you want to view the User menu in the menu bar: • By name: These are the longer names used as user names on login. • By short name: These are the names of each users’ home folder. • By icon: A head-and-shoulders silhouette. From first to last, these different options take up less menu bar space.

  14. 14. MANAGE LOGIN AND STARTUP ITEMS Mac OS X has two types of items that it launches at startup or at login. The names Apple uses for these items has fluctuated in previ- ous versions of Mac OS X; since Tiger, Apple has returned to a more logical naming convention: • Login items are applications, documents, or folders that become active, launched, or open when you log in to your account, whether at startup or later. • Along with login items, Mac OS X has startup items—low-level programs that activate when the Mac starts up, before any users log in. These startup items include drivers, kernel extensions, network services, and other items that affect the Mac as a whole, no matter which user is logged in. Both login and startup items play important roles in the operation (or lack thereof) of your Mac, and troubleshooting problems they may cause requires using different accounts. Login Items You can set up login items for your account in the Login Items section of the Accounts preferences pane (Figure 12). You can view this section only for your own account. FIGURE 12 The Login Items section in Accounts system preferences lists items that open automatically on login. The first three items shown here are programs; iTunesHelper is a background application that iTunes adds, and it and iCal will be hidden after they open. Fourth in the list is a document. Then comes my Documents folder, and then my iDisk. Page 57 This is a free sample of “Take Control of Users & Accounts in Leopard.” Click here to buy the full 88-page ebook for only $10!
  15. 15. TROUBLESHOOT STARTUP AND LOGIN ITEMS I suggested creating an account for troubleshooting earlier, in Set up a troubleshooting account; now, here’s a brief explanation of how to use this account—or the Guest account—to troubleshoot startup items and login items. If you notice a reproducible problem with your Mac, that is, a problem you can make happen again by doing certain things in a certain order, or if you experience a problem that happens quite often (even if you’re not sure why), you can test if startup items or login items are causing it. Here are the steps: 1. Decide whether to use a troubleshooting account or the Guest account: • If you need administrator access in order to reproduce the problem, then create a new administrator account (if you don’t already have one) for troubleshooting. This account should be a virgin account, with no additions, drivers, or extra software (See Set up a troubleshooting account, earlier.) • If you don’t think you’ll need to authenticate and don’t want to bother with setting up a new account, activate the Guest account in the Accounts preference pane. Leopard creates the Guest account anew at each login, so the account is always “clean.” 2. Log in to the account you chose in Step 1, and see if your problem disappears, either by trying the specific actions that cause it to happen or by working for a while in a way that typically brings on the problem. • If your problem goes away: There’s a good chance that it relates to your normal account. Specifically, one or more login items may be the culprit, but your problem could also be caused by certain user preferences. Continue with Step 3, next page. • If your problem doesn’t go away: Then it has nothing to do with a particular account; skip ahead to Step 5. NOTE Problems can occur for many reasons besides just bad login items or preference files, and this book is not designed to diag- nose them. For help, see Learn More near the end of this book.

  16. 16. TROUBLESHOOT PREFERENCE FILES Each account has many preference files, which are stored in ~/Library/Preferences. Many, though by no means all, of these files have names ending with .plist. Sometimes these files can become corrupted—this can occur if an application crashes, if you have a kernel panic, or if a program writes the wrong data in a file. Corrupted preference files can cause crashes and freezes, and, if these files affect the system, as opposed to indi- vidual applications, they can lead to widespread problems. If you think you have a problem with a user account’s preference files, try Steps 1–2 in “Troubleshoot Startup and Login Items,” previously, to find out for sure. To troubleshoot a problem with user preferences, follow these steps: 1. Remove preference files for any applications that are causing prob- lems. For example, if you’re having problems in the Finder, move the com.apple.finder.plist file to the Desktop, then log out and log in again. If you’re having problems with a specific applica- tion, quit the application, move its preference file, and then launch it again. Warning! Removing a preference file may cause an application to think it hasn’t been registered properly. That’s why you should keep the old preference file until you’re sure it’s the problem, and even then, don’t throw it out until you verify that you have the registration code for the application in question. If you remove a preference file from the Preferences folder, the associated application will recreate it on the next launch. The new, default preference file won’t contain any custom settings you’ve applied. (The old preference file, the one on the Desktop, still holds your settings.) 2. Determine if the problem appears to be gone: • If your problem goes away: You’ve found the culprit (or narrowed the culprit down to one of the preference files you removed). Go ahead and delete the offending file and get on with your life. However, if you are missing custom settings, Page 66 This is a free sample of “Take Control of Users & Accounts in Leopard.” Click here to buy the full 88-page ebook for only $10!
  17. 17. SHARE FILES AMONG USERS If several users have accounts on the same Macintosh, it’s likely that they will want to share files among their accounts. One user will want another to check his report, or give pictures he received by email to other users, or all users may want to access common media such as digital music files or photos. You can share a file on a Macintosh using one of four common loca- tions, each of which has pros and cons. I summarize these methods in Table 3, next page, and I discuss each option more thoroughly later in this section. NOTE Although I talk here about sharing files among users on the same Mac, I’m not talking about file sharing, which involves sharing and accessing files on two or more computers over a network. If none of these options seem sophisticated enough for your requirements, you may wish to look into file sharing and the various options it includes, such as dedicated file- sharing servers, FTP servers, and more. That’s the subject of another Take Control title, Glenn Fleishman’s Take Control of Sharing Files in Leopard.

  18. 18. APPENDIX A: SHARE DIGITAL MEDIA FILES Lots of people want to share songs and photos that are stored on their Macs, and the most common tools that Mac OS X users use to access shared media are iTunes and iPhoto. By default, when a user first launches iTunes or iPhoto, the program creates its own storage folder inside that user’s home folder. iTunes creates ~/Music/iTunes and iPhoto creates ~/Pictures/iPhoto Library. (iPhoto 7 no longer creates a folder, but rather creates a single iPhoto Library file, which is actually a package, a folder that looks like a single file.) Despite this similarity in storage, you use different methods to share music and photos among users on a Mac. NOTE ACTIVE VS. PASSIVE SHARING In this section, I show you how you can share libraries so you can both read and write; that is, add files to an iTunes or iPhoto library as well as listen to music or view photos. Both iTunes and iPhoto offer passive, or read-only sharing, via Fast User Switching. If, for example, Henry wants to listen to Ralph’s music, he can do so if Ralph has logged in and launched iTunes in his account. Then, when Henry logs in to his account with Fast User Switch- ing, he will see Ralph’s library in iTunes (if iTunes Sharing has been turned on in the iTunes preferences; see the iTunes online Help if you need details.) The same is true for iPhoto. Share Your iTunes Library It’s easy to share media in iTunes because iTunes is happy to load its files from any location. Follow these steps: 1. If you have already ripped some of your CDs to MP3 or AAC files, copy your ~/Music/iTunes/iTunes Music folder to the Shared folder. Otherwise create a new folder in Shared called iTunes Music. You can also put the iTunes Music folder on a shared local volume; see Share Files via a Shared Volume, earlier, and adjust the instructions in Step 2b accordingly.
