27. Advantages of Mac OS
 Easy to use
The Mac OS is much easier to use than any other operating system. Even
people who are not familiar with it can operate it easily.
 Integration With Apple and Other Products
Mac OS will automatically recognize and work with any other Apple
product, such as iPhone, Cinema Display, Airpod, and iPad. On top of this,
additional drivers are rarely needed for non-Apple products.
 Mac OS can run Windows at the same time
Mac OS runs on Intel chips, which means you can run XP or Vista
concurrently with Mac OS, with Boot Camp or Parallels software.

28. Advantages of Mac OS
 Reliability
Because OS X was designed from scratch from the ground up,
Mac OS is incredibly stable. Apple controls production from start
to finish, so every part of a Mac is designed and tested to work
together.
 Design
It’s engineered to take full advantage of what the hardware is
capable of. And it’s designed to deliver the most intuitive and
integrated computer experience in the world.

29. Disadvantages of Mac OS
 Gaming
If you're a computer gamer, Mac OS isn't going to do it for you.
Boot Camp and Parallels will allow you to run games natively in
Windows, but there may be a performance hit. Some games are
produced for Mac OS, but the number is very small.
 Price
All that flashy secure reliable power comes at a price. Macs cost
more than machines that run other operating systems. The result
is you're paying a premium to have what is often the highest-end
hardware on the market.

30. Disadvantages of Mac OS
 Fewer Software Options
Not all applications are yet available for Mac Unlike Windows.
 Cannot be upgraded/customized
There are upgrade options when you buy a Mac, but unlike a
Windows PC, you cannot mix and match components. The
easiest way to upgrade a Mac is to buy a new one.
