Multiple GUID_partition_scheme, cant boot MacOS High Sierra, and gpt command resource busy I have a problem after deleting Kali OS from my dual-boot Macbook (with High-Sierra MacOS). The problem is:


I can only boot into internet-recovery-mode
I can not use gpt command, as it results: 'resource busy'
The partition types got hosed by removing Kali Linux. Disk0s2 and disk0s3 got the wrong types. I would expect some Apple partition type for disk0s2 (HFS+/CoreStorage/APFS) and a Linux partition type for disk0s3. Disk0s4 is probably some dispensable Linux boot/swap partition.

To regain access to macOS you have to modify the partition type of disk0s2.


Boot to Internet Recovery Mode
In the menubar open Terminal.app and enter:

diskutil list
gpt -r show disk0


to get all partition and volume details of the internal SSD
Unmount all disk0 related volumes and disks (in your example that's disk2 (based on disk0s3), disk0s4 and finally disk0). Examples: diskutil unmountVolume disk0s4 or diskutil unmountDisk disk0.
Remove the APFS container disk2: diskutil ap deleteContainer disk2
Remove disk0s3 and disk0s4 (either with diskutil or gpt).
Example: diskutil eraseVolume "Free Space" Nil disk0s4
Determine the partition type of disk0s2 (How can I make my Mac partition bootable again?) and remove and re-add disk0s2 using gpt with the same size but the proper type. Considering the macOS version (10.13) and the hardware (SSD) the proper partition type is probably 7C3457EF-0000-11AA-AA11-00306543ECAC (APFS) instead of FFFFFFFF-FFFF….
Expand disk0s2 with diskutil ap resizeContainer disk0s2 0.




Under certain circumstances you have to disable SIP to edit the partition table with gpt!
