  • Loosen the three Phillips screws securing the access door to the bottom edge of your iMac.

  • These screws will remain captive in the access door.

  • Remove the access door from your iMac.

  • During reassembly, fasten the access door loosely and align it with the pocket cut into the outer case of the iMac before fully tightening the screws.

I am going to put a very important comment here. Before you start this process listen to the fans on your iMac do any of them sound obviously loud (think about how quiet your iMac used to sound as a reference) If you notice one or more of them sounding substantially loud compared to the others consider locating a replacement fan prior starting this process. After all if you are already “in the neighborhood” it is a shame to do all this work only to have to disassemble your imac a couple weeks later because you realize the fan is failing. I speak from my own personal learning experience of having to disassembly my iMac 3 weeks later because the HDD was failing and apparently the moving the fan around was just enough to push it to start really under performing.

Use your fingers or the tip of a spudger to slide the black plastic RAM tray pull tab out of the RAM slot.

Pull the black plastic tab away from the iMac to eject the RAM chip from its socket. The RAM modules are firmly seated and may require a fair amount of force to remove.

How many 4MB cards can I install?

nowsc - Yanıt

None. 4mb ram is too old to fit into any computer manufactured after like 1998.

Brett Davison - Yanıt

@Brett

I suggest that you learn your unit symbols before you try to appear clever:

4mb == 4 milli bits

4MB == 4 mega bytes

nowsc was obviously meaning 4GB not 4MB, try not to be a dick.

Take care to note which way out the RAM comes - there is a notch in each RAM and it is not centered, therefore either the notch will be on the left or to the right (depending on which way up you have your iMac). This will make it easier to replace the RAM without damaging anything.

Mike Haines - Yanıt

If damaged the notch inside one pair of RAM slots, is it fixable ?

My iMac 21.5-inch Mid 2011 has EMC 2428, but still directions turned out to be the same.

I replaced the memory in my MacBook Pro, and used the old cards (2x2GB) to fill out the 2 empty slots that apple left empty, doubled the memory of 2 machines for the price of one ^_^
