每次单击分区按钮时，Mac 上的磁盘工具都会崩溃

Question

I got an issue with my Disk Utility software. Every time I click the partition button with my ssd selected, it just crashes.I got an error:

Application Specific Information: Performing @selector(buttonPressed:) from sender NSButton 0x604000150490 Assertion failed: (self.minimumSize <= totalSize), function -[SUPieSlice initWithPartition:startLocation:totalSpace:], file /BuildRoot/Library/Caches/com.apple.xbs/Sources/DiskUtility/DiskUtility-1646/StorageUtility/CustomUIWidgets/SUPieSlice.m, line 62.

I've looked around and tried some solutions:
Run the hard disk check and no help. I've got a warning

Warning: Over allocation detected on main device.

Reboot with Command + S and run fsck -fy.
No help either.
I'm using a macbook pro 15 2017 with macOS 10.13.4

Answer 1

(To the tune of "Let it Snow")

• Oh, the Disk Utility is crashing,
• and the answer's worth rehashing:
• When the software isn't worth a lug,
• file a bug, file a bug, file a bug.

Answer 2

I was suffering from the same problem. What finally helped was this: https://discussions.apple.com/thread/8092082

In short: there was a dataless Time Machine snapshot on my drive, and deleting it fixed the problem with Disk Utility.

Answer 3

I had the same issue and it was because of a second unmounted sparse disk image I had to ensure was unlocked as well. Partitioning and access worked fine from DiskUtility after that.

Answer 4

I had the same issue soon after creating a new, encrypted Time Machine volume. One partition on the disk would mount but not the TM partition. Not sure how I got in whatever state it was, but I restarted and the next time I plugged in the drive, I was asked for the password, and the Time Machine volume mounted.
