When trying to run a clean install from download, an error pops up that says "Corel Painter is using a resource not available in this version of macOS". This error never shows up again.
Later, when trying to run, Painter never launches or shows anything. It immediately exits without displaying any UI elements.
My machine (2018 iMac i7 with 4K display) runs Painter 2018 without any issues, and had no problem at all with the 2019 trial.
Here's the crash log:
Sep 9 19:21:44 Corel Painter 2020: objc: Class NativeTimerMacPrivate is implemented in both /Applications/Corel Painter 2020/Corel Painter 2020.app/Contents/MacOS/Corel Painter 2020 (0x1057781c8) and /Applications/Corel Painter 2020/Corel Painter 2020.app/Contents/Frameworks/UXInterface.framework/UXInterface (0x10d4d5810). One of the two will be used. Which one is undefined.

We can try and help you out...A couple of questions...
1. Are you using an imported workspace?
2. Have you tried re-downloading 2020? Sometimes unusual errors like this are caused by incomplete or corrupt downloads.
1: can’t import a workspace if the app doesn’t launch
2: yep, twice
Ok, here's another idea (a hunch, may not work but interested if it does)
Go to your Mac System Preferences >Security and Privacy and find the "Microphone". Is Painter 2020 listed under there? Try toggling the checkbox...launch...any luck? Toggle it again, and launch...hopefully this will ensure the dialog pops up asking permission to use the Microphone (I've seen this issue on earlier versions of Mojave...it's not the Painter isn't launching, it's that for some reason the dialog is hidden and/or not showing.
Yep, that was the first thing I did
are you on the latest mac os build, 10.14.6?
painter 2020 installed just fine for me a few OS iterations ago, but I feel like apple might have tightened their security regulations over the few past releases. I remember painter 2020 took very long to install compared to the previous version, for reasons unknown.
keep in mind that if you're installing a trial, painter will have a service pack coming out sometime in the middle to late fall;
sometimes, however, corel fail to address critical issues like yours until the next major version (those typically arrive in late June), so you might want to consider a refund if you've paid for the software already.
btw painter should run successfully even if mac os has blocked the custom audio driver corel are installing on your system; you won't have audio-based brushes available in that case, but that's about it.
