Mac Mini running Sierra.
I have a 500GB internal drive, that was partitioned into two volumes because at one point I wanted to test upgrading from Mavericks to Sierra but wanted to make sure everything worked before I would commit to it. Everything has been working for a long time now so I'd like to remove the "old" system and reclaim that space.
Diskutil List showed both drives and their corresponding Recovery HD partitions. I did a
diskutil erasevolume on both the old system volume, and the old recovery HD. They are now gone, and all that's left is my Sierra volume and its recovery HD. But now I can't get the Mac to allow me to reclaim the old partition's space.
Here is my current
/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 249.0 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 /dev/disk2 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *8.0 TB disk2 1: EFI EFI 209.7 MB disk2s1 2: Apple_HFS TM iMac 8.0 TB disk2s2
diskutil resizevolume but every time I do I just get
The new size must be different than the existing size despite specifying a different (larger) target size.
Additionally, in Disk Utility I cannot create a new additional partition anymore, as DU seems to think the entire available space is now only the 250GB of my Sierra partition. Creating a new partition only eats into my 250GB partition's space.
How can I reclaim the missing half of my hard disk?
