Typing in the terminal diskutil list
gives me this...
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *500.1 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 499.1 GB disk0s2
3: Apple_HFS Recovery HD 629.1 MB disk0s3
I try to change disk0s3
to type "Apple_Boot", by using...
sudo asr adjust --target /dev/disk0s3 -settype "Apple_Boot"
But I keep getting the error...
asr: Volume adjustment failed: Operation not permitted
The partition isn't mounted. I have also tried the command as superuser.
adjust
