Apple today said in a support document that the new Mac Pro may experience an unexpected disconnection of the internal SATA hard drive after waking from sleep. Apple said it is “aware of this issue” and will fix it in a “future macOS update.
Some models of internal SATA drives may unexpectedly disconnect from your computer after your Mac wakes up from sleep,” Apple said. This can happen if your Mac automatically goes to sleep or if you manually put your Mac to sleep. If you see a prompt saying that your disk was not ejected properly, you can restart your Mac to reconnect to the hard drive.”
As a temporary solution, users can prevent the Mac Pro from automatically going to sleep by opening the System Settings app, clicking on Display → Advanced…, and turning on the option to “Prevent automatic sleep when display is turned off.
As previously reported, the new Mac Pro was announced on Tuesday and features Apple’s M2 Ultra chip. The desktop has the same design as the Intel processor-based model coming in 2019, but because it uses Apple Silicon’s unified architecture, it doesn’t support graphics and users can’t upgrade memory, Apple suggests that customers who don’t need PCIe expansion consider buying the Mac Studio.
