I recently bought a new SSD drive, as my stored data amounts outgrew the old one a little bit. After copying all data using
dd if=/dev/disk0 of=/dev/disk1, I want to enlarge my system partition, but Disk Utility is failing silently and
diskutil resizeVolume /dev/disk0s2 R (first partition is the EFI boot volume), I receive following error message:
Error: -5341: MediaKit reports partition (map) too small
How can I resize my system volume?
