Look at this post to know why Apple MacBook Pro Space Bar Key is the most problematic key of all time.

1. Apple MacBook Pro Space Bar Key
Most Problematic of All Time

3. We have been in the laptop keyboard key
replacement keys for over 10 years, and the
space bar key from latest generation of Apple
MacBook Pro keyboards is the most problematic
key of all time.

4. We have even seen failures straight out of a
brand new box, no the key did not fall off, but
when you press on the key you can just tell
something was not right, when you deal with
keyboard keys like we have each and every single
day for the last ten years, you can just tell
something was off, and it turned out a clip was
broken on the space bar of a brand new
MacBook Pro keyboard key.

5. Apple’s decision to switch from the regular
scissor clip to the butterfly style clip was met with
lots of applause as it led to a much bigger key cap
for easier typing, a thinner clip means the actual
damsons of the keyboard was thinner, as the
main goal for a complete design of the keyboard
was to make a thinner laptop which they
achieve.. at a cost.

6. In general the keyboard functions and works fine,
not my favorite keyboard and I have detail my
personal displeasure about the keyboard keys in the
blog “lets talk about MacBook pro keyboard keys”
and “piece of dust can ruin a keyboard”.

7. We have repaired and inspected several thousands
of the butterfly clip style keyboards from fourth
generation MacBook Pro straight from the factory,
and can say the failure rate is higher than previous
design keyboard, we inspect and test the
keyboards in two categories, electrical and
mechanical.

8. Electrical meaning does the keyboard produce a
key when you press on it, and mechanical meaning
when you press on it does the key travel up and
down, and if there are any damage to the
keyboard, key cap and hinge clip, and the failures
on butterfly generation keyboard tends to be more
mechanical, and more likely than not its the space
bar key.

9. The previous generation MacBook Pro keyboard
was perfect, the keyboard functioned great, the
feel of the key, the travel of the hinge clip all
perfect, you actually feel like you are typing, its
what a keyboard is suppose to feel like and part
of the reason why apple sold millions of them.

10. Comparing second and third generation to
the fourth generation space bar keyboard
key

11. The above picture shows both generation of the
keyboard with the key cap and hinge clip removed,
and you can see the fourth generation went
through a dramatic change with many changes
from going with plastic secure clip versus metal
clips, and a reversal of the plastic rubber silicone
cup to the newer style metal mechanical button of
sorts.

12. The most obvious change was the hinge clip, the
second and third generation every space bar key
uses two smaller hinge clips one on the left and
right side made of plastic, the fourth generation
is one continuous plastic hinge clip with two
metal enforcement bar top and bottom.

13. The metal bars are there to give support but also
give the clips from the back of the key cap
something to grab on to, note when installing the
key cap the side with the metal bars always face
down so if you can see the full length of the two
bars, you have it backwards.

14. The Second and Third generation space bar key
was made of translucent plastic with two rather
heavy duty reinforcement bars at the top and
bottom.

15. The fourth generation version went with a
complete metal key which should infect make the
key stronger and more reliable, but in reality this is
root of all complaints with MacBook Pro keyboard.
We found the plastic clips from the back of the key
to be very fragile and tend to break off from
moderate use, or from heavy pounding of the
keys.

16. We note earlier some keyboards were damaged
straight from the factory, so make sure you inspect
all legs and clips from the back of the space key
cap, if any of them are damaged or broken off
then its time for a replacement as you do not want
to prolong the issue as it may also lead to hinge
clip and damage to the entire keyboard.

17. Closer Inspection of the Keyboard Key Cap
and Hinge Clip

18. Make sure to inspect all points on the back of the
keyboard key cap, to the untrained eye everything
looks fine, but if the tabs are broken then it will
make installation of the key impossible, save
yourself the hassle and inspect before installation.
In the example above the clips on the top left left
and bottom left are both damaged.

19. The one piece hinge clip on the space bar key
should have sixteen points of contacts or hinge
clip legs, in the picture above four are missing, so
if anyone is missing or damaged then you would
need to a new hinge clip before proceeding with
the install.

20. I hope you find this helpful and give you some
perspective on the Apple MacBook Pro Space Bar,
its design, flaws, and ultimate reason we think its
the most problematic key of all time.
