Installed without issues. Using the latest versions of AppleALC (1.4.5), WEG (1.3.6), and Lilu (1.4.1) w/Haswell integrated graphics (no DRM for Apple video apps but that's not new/I'll live) and on-board audio (ALC898). Pro-tip, if you've limited your USB patches to load with a specific version of macOS, you've gotta change that in Clover (I initially forgot).
Successful update of HP Elite 8300 MT from 10.15.1 to 10.15.2. Updated Lilu and WEG with latest in EFI/Clover/kexts/Other. Two reboots (auto selected boot partition -- I have dual boot system with windows 10) followed by third boot by manually selecting the Catalina boot partition. All seems to be working. I use an USB stick for sound, so I have not checked if board audio is working.
