Catalina: The startup disk does not have enough space to be partitioned.

[onceways]

Hi folks.

I have one of the new MacBook Air's with the latest beta of Catalina on it, I'm trying to set up a Bootcamp partition but keep getting the error: 'The startup disk does not have enough space to be partitioned.'

• Disabled Timemachine completely
  
  
• run diskutil ap resizeContainer /dev/disk0s2 limits
  
  
• run sudo tmutil thinlocalsnapshots / 999999999999
  
  
• Rebooted
  

No affect, my partition looks like this:


MacBook:~ onceways$ diskutil list

/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *500.3 GB disk0

1: EFI EFI 314.6 MB disk0s1

2: Apple_APFS Container disk1 500.0 GB disk0s2

/dev/disk1 (synthesized):

#: TYPE NAME SIZE IDENTIFIER

0: APFS Container Scheme - +500.0 GB disk1

Physical Store disk0s2

1: APFS Volume Macintosh HD - Data 349.1 GB disk1s1

2: APFS Volume Preboot 81.5 MB disk1s2

3: APFS Volume Recovery 527.6 MB disk1s3

4: APFS Volume VM 1.1 GB disk1s4

5: APFS Volume Macintosh HD 15.2 GB disk1s5



Any ideas?

Standard partitioning requires contiguous physical space. Disk Utility will try to move content around, but might not have nougat space. Odd to see that as an issue with what is likely an SSD.
The quickest way to resolve it is to back your system to external drive using Carbon Copy Cloner and to wipe the disk, the partition, then restore. I have run into this and found this by far faster than other methods.
I always have CCC copies for my system in addition to TimeMachine. So I rarely start from scratch.
