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.
  • Create a bootable flash drive. If you need step-by-step instructions on how to create a bootable Flash Drive:
  • Reboot. Holding down the alt (option) key
  • Run the installer from the flash drive
  • Open the terminal from the menu bar/utilities
diskutil umountDisk disk0
diskutil umountDisk disk1

gpt destroy /dev/disk0
gpt destroy /dev/disk1

diskutil appleRAID create stripe Storage JHFS+ disk0 disk1

diskutil umountDisk disk2
gpt create disk2
gpt add -t hfs disk2
  • Open Disk Utility select disk2 format to APFS and install macOS Catalina.
  • The installer will continue again after the restart.
  • At the end you will see that the system cannot be installed. Reboot with the removed flash drive.
  • 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
/sbin/mount -uw /
mv /usr/standalone/bootcaches.plist /usr/standalone/bootcaches.bak
  • Restart
  • Select the flash drive installer again and boot
  • Choose Post Install patch.
    • check Apfs patch and SIP patch
    • check force rebuild cache
  • Finally Restart & Whala!


Post install

  • Open Terminal (Trim support)
sudo trimforce enable
