After my upgrade on my MacBook Pro to Catalina 10.15.4 my mouse no longer works on my Thunderbolt adapter A1632. Also, I need to put pictures onto a flash drive but I cannot see if my MacBook is recognizing the drive from the adapter.
MacBook Pro 13", macOS 10.15
I understand you have an Apple Thunderbolt (USB-C) to USB Adapter that stopped working after updating macOS, is that right?
If that's the one it should definitely work. First try restarting your Mac in the usual manner. If that fails to restore its operation, an SMC Reset is justified: How to reset the SMC of your Mac
MacBook Pro 13" 2019. Wow! I just changed the port to the other one and now the mouse is working! Thank you.
Just to be sure are you referring to this adapter? USB-C to USB Adapter - Apple
If so, what is the make & model of both your USB keyboard and USB external flash drive? Also, the exact model of your MacBook Pro? Have you tried using this adapter with another USB-C/Thunderbolt 3 on your notebook?
You're very welcome! Excellent! I'm glad you got it working.
Forgive me if this is a duplicate question.
