The new Sketchup Pro download returns the warning message “SketchUpPro-0.d Resource busy”. I tried using the Disk Utility app to verify as a way of making this work to no avail. I was excited to try this version because since installing Big Sur on my Mac my wireless space mouse no longer works with SUP. Any help is appreciated
I don’t know what the Resource busy message means. How did you install SU 2021? You should open the downloaded .dmg and in the resulting window drag the SU icon onto the Applications icon. Then close the install window and eject the .dmg. If you are trying to run directly from the .dmg, that will cause errors.
3DConnexion has a beta of a driver compatible with Big Sur, but they say it is not yet compatible with SketchUp. So on that one you will need to wait for them to finish testing. SU 2021 is compatible with Big Sur, but it can’t fix issues with the 3DConnexion driver extension.
