MacOS Catalina 10.15.X

With the release of macOS 10.15 Apple has blocked the install onto the MacPro 5,1. With all the updated hardware on my MP51 (Metal Capable GPU, and newer WiFi/BT card), there is no valid reason for this limitation. Thankfully the members of the Mac Rumors forums (specifically dosdude1) have created a “patcher” tool that allows for installing Catalina on nearly all of the recently “Apple-Blocked” models.

So much for Apple’s unreasonable planned-obsolescence. Here is a link to dosdude1’s Catalina-Patcher.

My MP51 has been happily running Catalina for weeks now. Kudos to dosdude1.
