    Or do I need to sell my 5,1 and move over to PC?

    Last time they said support for Mac Pro 5,1 will come later. This time they dont
    Well, regardless of whether or not they do, it's extremely easy to get running on one. It requires no patches outside of disabling the compatibility check on boot, and it runs perfectly fine.

    I am running it on a 5,1 with upgraded WiFI/BLE card and the OS installed on the disk via another system.

    You have to disable the system check - sudo nvram boot-args="-no_compat_check"

    Works ok for an early beta. The App Store has issues authorizing some apps that work fine on a MacBook Pro.

    macOS Catalina runs great and very smooth on MacPro5,1. No need to patch or upgrade.

    You just need to do these 3 simple steps for the MacPro5,1 to run macOS Catalina:

    (1) install macOS Catalina on a drive on a supported Mac

    (2) boot your MacPro5,1 to recovery, and then in terminal, type

    sudo nvram boot-args="-no_compat_check"

    (3) transfer the drive with macOS Catalina installed to the MacPro5,1 and and boot. The MacPro5,1 will now boot up macOS Catalina.

    So when the GM comes out there will most likely be a patch made though right?
