(I don't see anything wrong with what you were doing, by the way the installer needs a formatted disk to install to.)Ĩ) Close Disk Utility and begin the Mojave install. There is no need to write zeros across the entire disk (and doing so unnecessarily wears down SSDs).ħ) Close Terminal, then reopen Disk Utility and erase the zeroed disk as you described in your post above. If you have not removed all other disks from the system, consider shutting down to remove them and then restart this procedure from the beginning.Ħ) After the zerodisk command has run to about 2–3%, press ctrl+C to stop it. Disk identifiers can (and often do) change every time you reboot your system, so always check the identifier before running the command. You must specify the correct disk in the Terminal command or you will erase the wrong disk.

If there is no 'Unmount' button and instead you see 'Mount,' do not click the button this means the disk is already unmounted and you can go to step 4.Ĥ) Close Disk Utility, then launch Terminal from the Utilities menu.ĥ) Enter the following, but replace 'diskX' with the identifier you noted from step 2:Ĭaution: This command destroys data. Example: In your screenshot above, the 'Apple disk image Media' disk that you selected is shown as 'Device: disk2.' You should note the identifier for your Macintosh HD disk.ģ) Click the 'Unmount' button in the Disk Utility toolbar to unmount Macintosh HD. You can reinstall the other drives after you're confident the system is working as intended.ġ) Boot the macOS Mojave installer USB drive that you created, then open Disk Utility.Ģ) Select the Macintosh HD disk (or whichever disk you want to install to) and note the disk identifier that's displayed in the lower right side of the window. I also suggest removing all drives from your Mac except the 'Macintosh HD' disk while you perform the install. (I edited this sentence for clarity, after posting.) I also recommend that you write zeros to a portion of your 'Macintosh HD' disk to resolve the problems you're seeing with erasing and partitioning the disk. I also have a 512GB SSD Macintosh HD connected via PCI and this is where the Mojave lives I had upgraded my bootrom to 144.0.0.0.0 to run Mojave however, having inspected the system information whilst writing this, it seems it has somehow jumped to 9999.9.9.9.9Ĭurrently i have 2 SATA's (2 TB each), Storage A (empty) and Storage B - Time machine. I did try to reinstall Mojave via the Mac Recovery but it was not a clean install.

I did make a clone copy of my Mojave drive (using the trial version of CCC thanks to Dayo's advise) however, it was a recent clone installed onto a USB stick and is pointless to reinstall.

I would like to find out the best method how to reinstal a clean copy of Mojave and starting from there.

I have unsuccessfully attempted to install OpenCore onto my cMP 5,1 running Mojave using the several methods listed on CDF's thread 'Opencore on the Mac Pro'.Īs a result i have made a butchers out of it and I feel my entire desktop has been compromised.
