Verison History

This update includes:

Previous Changes in 1.4.x:

  • Fixed an issue where Safe Mode may not work on some systems

  • Added more warnings to alert users if their machine needs a system firmware update in order to boot from APFS volumes

  • Fixed an issue where permissions for some third-party applications may not work

  • Fixed a minor SIP issue

  • Fixed an issue where brightness control and/or Night Shift options would not appear under the Displays pane of System Preferences

Known Issues

The following issues have been discovered to be affecting the current version of this patcher

  • 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.
