MacBook RAM replacement stuck loading

[aeroencychris]

I apologize in advance for even mentioning Apple on this forum, but for the record, it's technically not my laptop.

 

Anyways, my friend has a Macbook Pro (call this MBP A) that was running pretty slow, among other issues, and only had 4GB of RAM. I believe this is a Mid 2009 model. I had access to another laptop (MBP B ) which had 8GB of RAM, so I figured I could switch them. This is a Late 2008 model. Apple RAM is Apple RAM, right?

This didn't appear to be the case, however. MBP B took the 4GB fine, with a short loading bar on boot, then running fine. MBP A, however, didn't like the upgrade, and is still stuck on the loading bar, at about 25%.  Even after returning both laptops to their previous RAM setups, it remained on this loading screen. I've tried resetting PRAM, verifying errors with Disk Utility in recovery mode, just about everything. Safe mode (holding shift on boot), however, did boot on MBP A, with both RAM set ups. However, it's extremely slow, and not practical for use. Luckily, that means data can be recovered. How should I proceed from here?

You got cursed by the legendary apple certified ram bullshit thingy

 

It's totally random, in fact, any ram of any brand can or cannot work 

 

I installed 16 gigs of ddr 3 in my mid 2012 mbp and holy shit i freaked out when i was about to start it

Not that this will necessarily help you with your immediate problem, but I always go with Crucial certified Apple-compatible RAM.   Apple charges a kidney for their RAM, so I go for the Crucial RAM which is a third of the price.  Just google Crucial Apple RAM.

I always do this anyways with new RAM, but I'm not going to go out and buy new RAM for this. The original ram should work anyways.

I really hate to bump but my friend needs this computer ASAP, any ideas anyone?

Reset the PRAM and SMC.  My money would be on this fixing it.  

 

 

I don't think this is a RAM issue however.  I have never seen this problem caused by memory upgrades, and I have done a lot of them.
