Operating a Mac Professional 2013 with macOS Catalina. Seeking to change the GUID kind from FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF to 7C3457EF-0000-11AA-AA11-00306543ECAC. I have been shopping by numerous earlier posts about this concern however haven’t discovered the answer that I would like but or anybody having the identical downside.
After working the diskutil umountDisk disk0 and gpt take away -i 2 disk0 instructions, I went so as to add the disk again utilizing this command gpt add -i 2 -b 409640 -s 768896136 -t 53746F72-6167-11AA-AA11-00306543ECAC disk0 and received this error message gpt add: unable to open gadget 'disk0': Useful resource busy. I’ve observed as nicely that after working gpt -r present disk0, index 2 has switched from FFF… to MBR half 218 and disk0s2 is not listed when calling diskutil checklist. I can not appear to determine the place to go from right here.
Here’s what I’ve completed up to now
