Updated Ventura and my left mouse and track button stopped working

This morning my mouse and trackpad were working normally until I updated to the latest Ventura 13.4.1. My trackpad and mouse aren't working. Can't click and drag anything and when I regular clicked left button secondary dropdown opens as if it's now the right click. Very frustrating

MacBook Pro 13″, macOS 13.4

Give this a try: boot into Safe Mode according to How to use safe mode on your Mac and test to see if the problem persists. Reboot normally and test again.


NOTE 1: Safe Mode boot can take up to 3 - 5 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


NOTE 2: if you have a wireless keyboard with rechargeable batteries connect it with its charging cable before booting into Safe Mode. This makes it act as a wired keyboard as will insure a successful boot into Safe Mode.
