Hello Apple Developer Community,
I'm encountering a persistent issue while attempting to create a new partition on my Mac, and I'm hoping to get some assistance or insights from anyone who might have faced a similar problem.
Issue Description:
I'm trying to partition my internal drive. I initially used Disk Utility.app for this purpose. The partitioning process starts, but consistently freezes when it reaches approximately 10-20% completion. I've left it running overnight (for over 9 hours), but there was no progress, and the application remained unresponsive at that percentage.
After several attempts with Disk Utility, I decided to try using the diskutil commands in Terminal to see if that would yield a different result. I used commands such as diskutil apfs resizeContainer and diskutil partitionDisk. Unfortunately, these commands also result in the same behavior: the process starts, reports progress up to about 10-20%, and then completely freezes without any further output or completion, requiring me to force-quit Terminal.
