As Ram is so cheap at the time, I wanted to upgrade my MacBook Pro from 4 to 8GB. One criterion for the selection of this memory from Kingston were the many five star reviews. Along with the memory was even more come, so that the bag was not critical. The installation went smoothly, what natuer light is not but the Ramriegeln but the MacBook Pro. The store was immediately recognized and ran just four weeks without any problems. Then suddenly a crash from hibernation. After repeatedly crashes in operation after different times. And always from hibernation, immediately upon waking. Original Ram unlock the card installed: computer running stable again. Yet quickly brought to the post Luckily on the last day of the return window. I'll order the same memory again, maybe that was a Monday model.
