Ideally I would like to have a clean sweep and partition my 1 TB HD with Sierra and Snow Leopard sharing the HD. It's a real PITA with the High Sierra OS.

I have been trying terminal command to delete the recovery hd. Would you be able to help me with a similar problem you dealt with here?. I'm a newbie here but fairly familiar with Macs. Weaselboy.Just wondering.I see your status as green. This would get you the end result you want.īefore you do any of this at all, make sure you have a good backup in case things get sideways. So to summarize, we turned off core storage on Danny, then copied Danny to Fenix, the killed Danny and renamed Fenix to Danny. Lastly open System Preferences and in the Startup Disk panel select Danny as the boot disk. Then open Finder and select Fenix then hit the return key and rename it to Danny. Now you should be able to use Disk Utility from there to remove Danny (since we copied Danny to Fenix you won't lose anything) then resize Fenix to fill the disk. This will bring ups boot manage where you can select Fenix to boot to. Okay, once that completes, go ahead and reboot while holding the option key at startup. then you should have Danny selected where I have Macintosh HD on the dropdown. So using my example you should have Fenix selected where I have Backup selected. Looking at my screenshot I am restoring Macintosh HD to Backup. In the Restore from: dropdown select Danny then click Restore. Once Danny has completed the core storage revert, do a command-r boot to recovery. Second problem is Fenix is before Danny, so Fenix cannot be resized or removed.
