PSA - A few lessons I learned using open core

Opencored around 50 Macs at this point so figured I would share some useful tips I picked up along the way. Curious to see if you have any decent tips worth sharing too!

  • ALWAYS update the patcher before updating macOS
  • Ventura and Sonoma don't like 2GB ram sticks. 2x2 often fails to install, 1x4 often works
  • 2011 Macs seem a lot more stable on Ventura than Sonoma (Sonoma often fails to install for me)
  • The "disable firmware throttling" options is a good idea for iMacs, especially those with broken or missing screens
  • Always reformat the disk in disk utility during the install process. Formatting APFS in say High Sierra then attempting to install Sonoma can fail
  • Always install the latest version of macOS natively supported by the Mac first as this can sometimes contain important firmware updates that cause an OC install to fail
  • On a cheesegrater pro, you can enable the GOP GPU patch to bypass the no boot screen when using a PC GPU Issue
