      • — The 2007 iMac 7,1 is compatible if the CPU is upgraded to a Penryn-based Core 2 Duo, such as a T9300.
    • 2006-2008 MacBooks:
      • MacBook1,1
      • MacBook2,1
      • MacBook3,1
      • MacBook4,1
  • 2008 MacBook Air (MacBookAir 1,1)

  • AMD/ATI Radeon HD 5xxx and 6xxx series graphics acceleration: Currently, it is not possible to achieve full graphics acceleration under Catalina on any machines that use a Radeon HD 5xxx or 6xxx series GPU. If you have a machine with one of these GPUs installed, I’d advise upgrading it if possible (can be done in 2010/2011 iMacs, iMac11,x-12,x), disabling the dedicated GPU if using a 2011 15″ or 17″ MacBook Pro (MacBookPro8,2/8,3, instructions to do so can be found here), or not installing Catalina. Running Catalina without full graphics acceleration will result in extremely poor system performance.
  • 2008 Mac Pro 3,1 AMD GPU Support: FIXED as of Catalina Patcher 1.2.0.
