Apple released the second developer beta of MacOS Catalina 10.15.1 on Thursday. No major new features have been uncovered in Catalina 10.15.1, but Apple is adding support for AMD Navi RDNA video cards for eGPUs.
macOS Catalina 10.15 was just released on October 7th.
Developers can register their Macs for the developer beta program at the Apple Developer Connection. If your Mac is already set up for Catalina developer betas, you’ll find the update in Software Update.
I’ve been using Catalina on my 2012 i7 MacMini since the upgrade was available. It broke a few applications but definitely worth the upgrade. Other than broken apps (32-bit) I have had no problems with it and it seems to be running very well for me. I was using Mojave and it seems just as solid as Mojave in my daily use. I have installed all the minor Catalina updates and everything has gone smoothly. My Catalina install over Mojave took quite a bit of time due to my slow 5400rpm drive, but I had no issues. I think Catalina is definitely worth upgrading to unless you have a 32-bit app that you really need to use. I was really sad when SMBUp broke, but I started using SFTP instead of SMB to connect to my Fire TVs so I could pass files back and forth.
upgrading is very good, looking forward for this one.
