I have a Cubase Artist 10 on Max OSX and the Absolute 4 library. When I use Steinberg Library Manager to move Absolute files to an external hard drive it seems to work and shows files being moved but a lot of space is still being used on the original drive after the operation. As a result I’m out of space on my original drive even though there should be plenty left if all of the Absolute 4 files had successfully moved. Has anyone else encountered this issue?
Did you check (or is it uncheck 
) something like: “Keep Installation Files” when they were first installed using in the Library Manager?
You’ll have to find the files in order to know what they actually are. Maybe ~/Downloads/Steinberg/* ?
