The release notes for Mac OS 11 Beta 11 states that installing the beta in a volume will prevent future updates to other OS versions on that partition. With that in mind, I want to create a new partition, but I'm having problems.
First of all, I tried Disk Utility, but it won't let me change the existing partition.
In the partition screen, the '+' is disabled, and the screen says:
"This container has 236 GB used space.
Its minimum size is 449.96 GB.
This container can't be split, because the resulting containers would be too small."
So I looked into resizing the existing partition. In terminal, I entered:
sudo diskutil apfs resizeContainer disk1 450g
but it failed with the error message:
Aligning shrink delta to 49,963,175,936 bytes and targeting a new physical store size of 449,999,998,976 bytes
Determined the minimum size for the targeted physical store of this APFS Container to be 499,963,174,912 bytes
Error: -69521: Your APFS Container resize request is below the APFS-system-imposed minimal container size (perhaps caused by APFS Snapshot usage by Time Machine)
Does any know why this is failing, and how I can fix it?
