I'd like to add a 30GB exFat partition as a shared area accessible from both windows and macOS. Using the bootcamp utility the disks currently looks like this: /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 361.0 GB disk0s2 (free space) 10.0 GB - 3: Microsoft Basic Data ⁨BOOTCAMP⁩ 129.0 GB disk0s3 /dev/disk1 (synthesized): #: TYPE NAME SIZE IDENTIFIER 0: APFS Container Scheme - +361.0 GB disk1 Physical Store disk0s2 1: APFS Volume ⁨Macintosh HD - Data⁩ 245.5 GB disk1s1 2: APFS Volume ⁨Preboot⁩ 431.1 MB disk1s2 3: APFS Volume ⁨Recovery⁩ 1.1 GB disk1s3 4: APFS Volume ⁨VM⁩ 1.1 GB disk1s4 5: APFS Volume ⁨Macintosh HD⁩ 15.4 GB disk1s5 6: APFS Snapshot ⁨com.apple.os.update-...⁩ 15.4 GB disk1s5s1 I've tried to resize disk0s2 like this: diskutil apfs resizecontainer disk0s2 300G ExFat SharedSwap1 0 And receive the error: Aligning shrink delta to 60,999,999,488 bytes and targeting a new physical store size of 299,999,997,952 bytes Determined the minimum size for the targeted physical store of this APFS Container to be 360,999,997,440 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) Upon checking snapshots: diskutil ap listSnapshots /Volumes/Macintosh\ HD Snapshot for disk1s5s1 (1 found) | +-- DB4F6629-4C9B-41AC-A37F-B46CA4D1FA7B Name: com.apple.os.update-E64B3CD15985B90FDC72FFBC9FFB352590E652026671C1695E4EA97D9050DD14 XID: 3287758 (Will root to (boot from) this snapshot) Purgeable: No NOTE: This snapshot limits the minimum size of APFS Container disk1 Is it possible to resize and allocate more space, or should I just format and reinstall both operating systems again? If the latter is there a recommended process for my end result of Mac partition, Windows and shared exFat space?
