In a support document published on Wednesday, Apple said certain models of internal SATA drives might unexpectedly disconnect from your Mac Pro after your it wakes from sleep. Apple said it is “aware of this issue” and will fix it in a “future macOS update.”
Certain models of internal SATA drives might unexpectedly disconnect from your computer after your Mac wakes from sleep. This can occur if your Mac automatically goes to sleep or if you manually put your Mac to sleep. If you see a message that your disk was not ejected properly, you can restart your Mac to reconnect to the drive.
To prevent your Mac from automatically going to sleep, change the sleep settings on your Mac:
- Choose Apple menu > System Settings, then click Displays.
- Click Advanced, then turn on “Prevent automatic sleeping when the display is off.”
- Click Done.
Apple is aware of this issue and resolution is planned for a future macOS update.
Although the Mac Pro uses SSD storage, it has SATA ports to use to connect internal hard drives.
As a temporary workaround, users can prevent their Mac Pro from automatically going to sleep by opening the System Settings app, clicking on “Displays” -> “Advanced…,” and turning on “Prevent automatic sleeping when the display is off.”
The new Mac Pro boasts Apple’s most powerful 24-core CPU, an up to 76-core GPU, and starts with twice the memory and SSD storage. It can also be configured with up to 192GB of memory with 800GB/s of unified memory bandwidth. Both the Mac Studio and Mac Pro can play up to 22 streams of 8K ProRes video.
The new Mac Pro provides PCIe expansion, with seven PCle expansion slots, with six open expansion slots that support gen 4, which is 2x faster than before.
The Mac Pro offers eight built-in Thunderbolt 4 ports — six on the back and two on the top — twice as many as before. It supports up to six Pro Display XDRs, along with Wi-Fi 6E and Bluetooth 5.3. The Mac Pro also includes three USB-A ports, two higher-bandwidth HDMI ports that support up to 8K resolution and up to 240Hz frame rates, two 10Gb Ethernet ports, and a headphone jack.
