unexpected problem
In a support page update released the other day, Apple said that some SATA hard drives may unexpectedly disconnect from the 2023 Mac Pro after the computer wakes up from sleep. Apple said it is “aware of this issue” and will fix it “in a future macOS update.” While the Mac Pro is configured with SSD storage, it has SATA ports for connecting internal hard drives and some may disconnect due to an error.
For now, Apple states that as a workaround, Mac Pros can be prevented from automatically going to sleep by opening the System Settings app, clicking Displays → Advanced… and turning on the “Prevent auto-sleep when screen is off” option. The new 2023 Mac Pro is available for sale starting at $6,999.
