I am wondering if anyone is seeing this or if something weird happened in a repair: My 2016 MPB TB was having keyboard issues, so I took it in and they replaced the entire TB/Keyboard mechanism with one from a 2017 model. I brought it home, flattened it, and did a clean install of the OS. A week later, I have noticed the following: - machine goes to sleep with lid up - I wake machine up by hitting the spacebar, the TB lights up and I get the animation for TouchID - I put my finger on the scanner and the entire machine freezes up - I hard reboot and now the machine has forgotten my fingerprint entirely, I have to set it up again. This has happened repeatedly. So...I'm checking to see if anyone else has seen this kind of behavior before I take it in again for a replacement.
