I successfully installed Lion 10.7.2 but when I try to install the Recovery Update the Screen goes black and a Box appears telling me to hold down the Power Key to reboot my mac. I believe this is what is called a Kernel Panic. I tried finding a solution on Apples Website but to no avail. Does anyone know what is causing this and how I can fix this? Should I just skip the recovery update? Is there something wrong with my Hardware (please say no ) Thx for helping me!
