After upgrading to Catalina, when I open the lid after it’s been asleep, I get a message: “We couldn’t find a keyboard and mouse” ( screenshot ). It happened three times, and when it does, I open the lid, unlock with my fingerprint, and the keyboard and trackpad are dead. Can’t type nor move the pointer via the trackpad. After a few seconds, I get this: ( message ). I discovered that if I shut the lid and reopen it after a few minutes, it all works, but the last time I had to do that several times. Anyone else experienced this after the upgrade?
There was a corrupt file that had to be deleted. Here are the steps:
- Open Finder > Go
- Hold down the Option key, the Library pops up in the Go dropdown. Click on Library.
- Open the Preferences folder.
- Find the file that starts with “com.apple.HIT”… (I don’t remember the full file name, as it isn’t recreated later)
- Send it to the Trash and empty the Trash.
Please try the steps as suggested by another member. It’ll probably fix this issue.
