I find myself in a strange position where I have to ask my employer to purchase a new Mac, despite this $4,000+ MacPro being just a few years old. This is the only known resolution at the time.
Everyone is scrambling to find a solution for Apple. There have been many logical ideas, such as:
- Update your aftermarket SSD (people without an SSD experience this as well)
- Upgrade your RAM (people with 32 GB + experience this as well)
- Have fewer monitors connected to reduce strain on the GPU (is this acceptable though?)
- Clean install or downgrade macOS (doesn't fix. perhaps firmware has permanently ruined these computers until new firmware comes along)
- Reset pvram and smc
- Try various Onyx options
- Disconnect external media (in case delayed writes are causing this)
- Turning off pretty much everything you might find useful (Siri, Spotlight, Time Machine, iCloud)
- Disabling TRIM
- Apple fix memory leaks and bugs in WindowServer and Metal 2
We've noticed that music can keep playing through the freeze. The only apparent option is to power down by the button. Some have pointed out there is a way to shutdown cleanly through SSH, but that is for technical users that have some time on their hands.
