macOS 10.15.3 Update

[Ploddles]

Easiest update ever using OpenCore. Used combo installer and walked away. Much easier than Clover.

Same as my Clover one. Didn't have to touch the mouse or keyboard, the installer selected the correct option every time. I do have Native NVRAM working so that could be why.

Smooth update to 10.15.3 on Prime Z370-A rig using Clover 4961 and kexts in /L/E.

I strongly recommend updating your Clover to v2.5k r5102 or higher as my display only showed a black screen during (and after) updating to macOS 10.15.3, and my Clover build was v2.4k r4934 from MultiBeast 11.3.0. Only booting via my USB stick (Catalina installer) could finish the update.

It no longer requires my USB stick after removing the outdated Clover build and installing the latest Clover build from tonymacx86.

Updated from Mojave to this NP. I had to tweak my dual monitor set up, but everything works.

I finally succeed the upgrade from 10.15.2 to 10.15.3 which is a good news, all is working as expected.

But I had to remove the MSI Radeon RX 5700 XT for the upgrade. Because each time at upgrade startup my computer
was shutting down.

Updated to 10.15.3 on 970 EVO Plus successfully after updating and moving kexts to ...\Other and removing them from \Library\Extensions. Also ran Stork's Terminal commands to rebuild cache. Did not update Clover (5098) or Port Limit Removal patches.

Stable system so far with USB3 and audio working. Access to PC on separate 960 EVO retained.
