I've got a USB bus in the USB port on my Mini. I plug in an external drive for BUs. I also plug in a thumb drive for BUs. It all used to work. I upgraded to Sequoia a few days ago. Now the drives won't eject because something is using them. Tried logging out, powering down, etc. Nothing works except force eject. Has Apple got a bug?
Mac mini, macOS 15.1
I may have found a solution that doesn't involve erasing the drive.
Settings > Spotlight > Search Privacy > + add the external drive the exclusion list
This worked for me, but you need to manually add all external drives that you use.
And I have Samsung SSDs as well and do not have any problem mounting or ejecting them with Sequoia 15.2. Stop trying to pin this on Sequoia.
As the famous logic theorem states, correlation does not imply causation. It worked before, it doesn’t work now, therefore the update has caused the problem is completely false logic.
Do you actually think the millions of beta testers, developers as well as end users, would not have noticed such a show stopping bug as this before macOS 15’s release?
I agree with wagnercs. All my drives and San Disk Flash USB sticks worked fine before I upgraded to Sequoia 15.1.1 and later Sequoia 15.2. Now something is supposed to be using them, so they would not eject. It has to be a bug in Sequoia.
adrianhong's Spotlight solution worked for me - thank you for sharing this.
Same problem, Did that. User is "root" so what can i do?, this is a new drive, I can't format it, because "it's in use" and yes, sequoia 15.2.
Did the additions both drives to spotlight exception, no help.
funny though that my old hd drives eject without much of a problem. The drives having problems are both ssd's
This problem is now occurring again for me when I bought new UGREEN USB-C 18in extender cables for two of my Samsung Exteme SSDs. When I tried to eject, I got the same message, cannot eject etc. And when I tried to add it to Spotlight, it gave me an error. Clearly this is not fixed yet.
Hello all.
I'm having the same problem with some Crucial X9 USB-C external drives. Was hoping the latest update that just came out would fix it but still no joy. I tried doing the steps to add them to the Search Privacy list in Spotlight preferences but didn't fix it for me. Could really do with a workaround, I've only had the new M4 Max Macbook for a couple of months and its driving me crazy having to shutdown anytime I need to eject them.
Good post, @NicolasCastagne - and to you rpoint about bugs in the core OSX after updates I discovered this morning that after the forced OSX update (I am now on Sequoia 15.4.1 - yippee) when I booted my M3 MacBook Pro I got a message window about keyboard setup - the assistant - and finally that the keyboard (built into the MacBook, mind you) cannot be identified. And yet, as shown by these very words, it works.
This nonsense gets more annoying by the minute.
The most funny thing is that I’ve noticed this behavior with .ts files three OS updates ago if not earlier and submitted a bug report as well as calling Apple and getting to the engineers to fix it. Nothing changed.
Is this new Mini or an older version?
More info.
Disk Utility can't unmount the thumb drive to do anything to it.
Reported to Apple/feedback
I can read/write to thumb drive. Data seems fine. Just can't eject without forcing it
Etrecheck showed no major or minor problems. Where do I post the report?
BTW, TM is only backing up intermittently since Sequoia install. Set to do it daily. Any ideas about that?
Might report via www.apple.com/feedback.
Good work, great to hear!:)
Well it also happens when CCC is not involved at all - as in when I simply drag aa folder from my external SSD to the external HDD backup - FInder only.
