A “Disk Not Ejected Properly” error appears when waking the 2023 Apple silicon Mac Pro from sleep. This is clearly a bug, as Apple’s promised to release a fix.
Apple’s 2023 Mac Pro workstation powered by the company’s M2 Ultra chips suffers from a bug causing internal SATA drives to unexpectedly disconnect.
Some people see a “Disk Not Ejected Properly” error message after waking their computer from sleep due to the internal drives disconnecting.
2023 Mac Pro throws “Disk Not Ejected Properly” errors
Apple’s acknowledged that it’s aware of this problem and will deliver a software fix “in a future macOS update,” but wouldn’t say when it might drop.
According to a support document on Apple’s website, certain models of internal SATA drives might unexpectedly disconnect from the 2023 Apple silicon Mac Pro. This happens after the computer wakes from sleep, regardless of whether the computer went automatically to sleep or the user manually put it to sleep.
“If you see a message that your disk was not ejected properly, you can restart your Mac to reconnect to the drive,” Apple clarifies. The iPhone maker suggests modifying your Mac’s energy settings to prevent sleeping when the display is off.
The support document will be updated as more information becomes available.
How to prevent your Mac from automatically going to sleep
Follow these steps to stop your Mac from automatically going to sleep:
- Click the Apple menu and choose System Settings.
- Select Displays in the System Settings sidebar.
- Click the Advanced button.
- Turn on the switch labeled Prevent automatic sleeping when the display is off.
- Click Done to save the changes.
Your Mac will no longer go to sleep when the screen saver activates or the screen turns off. Announced at the June 5 WWDC23 keynote, the new M2 Ultra Mac Pro is available in the tower ($6999) and rack-mounted versions ($7499).
The wheels can still be had for $400 at purchase or $699 after that.
Why does the 2023 Mac Pro has fixed RAM?
The new Mac Pro looks the same from the outside as the Intel-based model from 2019 that Apple no longer offers. However, the new machine lacks two distinct features from its 2019 Intel-based counterpart. The first is user-upgradeable RAM.
In a nutshell, because Apple silicon uses unified memory soldiered on the chip, the 2023 Mac Pro can’t support user-upgradeable RAM even if it wanted to.
Why doesn’t the 2023 Mac Pro support graphics cards?
And even though the machine offers six PCIe expansions slots for audio, video, networking, storage and other cards, graphics cards aren’t and won’t be supported.
John Ternus, Apple’s hardware engineering chief, told Daring Fireball’s John Gruber that expandable GPU support for Apple silicon is not on the roadmap.
“Fundamentally, we’ve built our architecture around this shared memory model and that optimization, and so it’s not entirely clear to me how you’d bring in another GPU and do so in a way that is optimized for our systems,” he said in the video above.
“It hasn’t been a direction that we wanted to pursue.”
