Kernel Panics on Boot after RAM Upgrade
Hi,
I bought a used 2010 21.5" iMac. It only came with 4 GB of memory, so I decided to order this: http://www.amazon.com/gp/product/B002YUF8ZG/ref=oh_details_o01_s00_i00
I saw that they were DDR3, 1333MHz so they were compatible. Some of the reviews also said it was compatible with this iMac.
It did not work. As the title says, I get a kernel panic on boot. It does not even show the pinwheel when booting up normally. Just the apple logo and some details. My windows partition and recovery do not work either. I am currently writing this from Safe Mode, where it manages to start and recognize the RAM, somehow. Here are the crash details:
