You can find it under '/Applications/Utilities' or by typing 'Disk Utility' into Spotlight. Click the File menu and choose the menu option labeled 'RAID Assistant'. In the next dialog box choose the type of RAID array you'd like to create. Click Next when you're ready. In an ideal world I would have a RAID that all 3 of my OSes will read. (macOS, Windows, Ubuntu). I have switched my motherboard from AHCI to RAID mode and created a RAID using the integrated Intel controller. Windows and Ubuntu seem to be OK with this and are (now) booting just fine. However, macOS doesn't seem to be seeing eye to eye with RAID. Open the RAID Pane. First select an entire disk (not a volume) from the left pane of the Disk Utility window. Make sure that you're choosing one of the disks you want to add to the RAID array (and thereby protect its data redundantly or speed up its access with striping), not your Mac's startup disk.
At the time of output mac os 10.13 was removed support for boot from RAID 0 drives.
I was looking for a solution. Post on apple developer remained unanswered.
The @taruga solution on real macs needed to be run in single user. In Catalina, the system disc is read-only, which makes the task even more difficult
The entry describes step-by-step installation process
- Download Patcher from @dosdude1 site (@dosdude1 great job! ).
- Create a bootable flash drive. If you need step-by-step instructions on how to create a bootable Flash Drive see the video:
If you're using a Hackintosh. After creating the installer, install Clover on efi partition on usb installer. If your config and kext work with normal installation, they will also work with Raid. (If you need help with clover configuration you will find it on insanelymac)
- After creating the usb installer Reboot.
- Holding down the alt (option) key
- Run the installer from the flash drive
- Open the terminal remove the current raid and create the new one (the diskutil and gpt commands)
- Exit the terminal and open the disk utility and format the array APFS
- Exit disk utility and install macOS Catalina.
- The installer will continue again after the restart.
- At the end you will see that the system cannot be installed. Remove installer & Reboot
- this is necessary to continue with the internal drive and not with the installer on the usb
- The installation error will pop up again.
- click on the menu bar (call up by clicking on wifi) select the terminal from the utilities menu and type
- Restart
- Select the flash drive installer again and boot
- Choose Post Install patch.
- check Apfs patch
- SIP patch
- Be sure you rebuild caches too, the option will show itself after the patches been appleis and its counting down
- Finally Restart & Whala!
