Re: IMPORTANT: 10.7.4 and Unlocked Sandy Bridge CPUs [TEMP FIX]

We're working on this as we speak- and we don't have all the answers. But if you list all of your testing results with 10.7.4 here, we may be able to have a general discussion on how to fix it.

Thanks Tony! I'm sure I speak for the community when I say that we really appreciate your all of your efforts and dedication, particularly being available to help us resolve these kinds of issues when an update drops.

Updated and had the speed problem so made the change stated by macman. Now when booting it is giving me /Extra/com.apple.Boot.plist is depreciated. Please use the file /Extra/.org.chameleon.Boot.plist. Press a key to continue. What can I do to get it to change back to using the com.apple.Boot.plist. Any help would be great thanks.

Boot using UniBeast or rBoot, then install this from MultiBeast. It will give you a new plist that is org.chameleon.Boot.plist- that is the file you need using the latest Chimera- not the deprecated one.

Btw, I hope you guys backed up your 10.7.3 downloads from the App store if you're ever wanting to revert to it Just logged into the app store and noticed the 'update button' there as well on my 10.7.3 purchase.
