Hey @DJOGee
I just fresh installed SubLab XL on my computer so I could test out the importation again. I also have the exact same macOS as you.
However, I’m not having any issue importing any of those packs in the standalone app or in AU, VST or VST3 in Ableton. So maybe it’s a permissions issue?
Are you logged in as an admin with read & write privileges on your computer?
Could you please locate the SubLab XL folder ( …/Library/ApplicationSupport/FAW/SubLabXL), right-click the SubLab XL folder and the click Get Info?
All the permissions should be set to Read & Write:
