I have an Apple external CD Drive that works fine on IMac running Sierra.
On my MacBook Pro running Catalina it is not recognized.
Tried resetting SMC per older thread - didn't help.
tried two different USB-USB-C cables, no difference.
Thanks
MacBook Pro 13″, macOS 10.15
If you put a disc in the drive is it recognized then?
Are all of these checkboxes checked in the Finder's General preferences:
If still unrecognized boot into Safe Mode according to Start up your Mac in safe mode - Apple Support and see if the problem persists. Reboot normally and check again.
NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following;
• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts
• Deletes font caches, kernel cache, and other system cache files
