CJamesC Posted August 2, 2013 Share Posted August 2, 2013 I have a fully working Snow Leopard build and I was wondering what's the best route I should take for updating to Lion?

burkett375 Posted September 10, 2013 Share Posted September 10, 2013 I have a fully working Snow Leopard build and I was wondering what's the best route I should take for updating to Lion? My rig: SL 10.6.8 Phenom II x4 965 BE GTX 480 Biostar A770e3 16GB Ram Thanks in advance! Here's how I did it: Take your current SL setup and either create a new partition on the same drive, or get a new formatted drive all-together. I downloaded iatkos L2 while in SL and installed to the new partition using this package (hit show-hide files first): iATKOS_L2>System>Installation>Packages>OSInstall.mpkg (be sure to use the mpkg one) during custom install, have it look like this: after it installs, DO NOT REBOOT replace mach_kernel with Bronya's RC15 from the Lion AMD thread in the root of the installation Go to System>Library>Extensions and replace the AppleACPIPlatform.kext and IOPCIFamily.kext with the ones I attached in this post. (it looks like the uploaded files automatically added .zip extensions, so you'll just have to delete the .zip part before replacing.) go to disk utility and fix the permissions on the new Lion install, and reboot. Pick the lion partition at chameleon bootloader, use verbose and let's see if it works! If you get it up and running, do a combo update, replace the same 3 files, fix permissions, reboot and good to go again!
