[Sticky] Mojave does not support booting from RAID volumes

The fundamental principal is the partition map on a disk dictates what driver controls/manages that disk.
You can not have two drivers controlling the same disk.

So when a disk is in SoftRAID disk format, then the SoftRAID driver controls it and all volumes on the disk. So, if Apple says no third party startup disks, there is no way around it.

Users do set their user environment on SoftRAID volumes, which works.

:-(

Glad I protected myself with the "half-formed-thought" descriptor.

Thanks for replying.

For those of us booting off a SoftRAID volume presently:

I take it the only way forward is to convert the boot volume to AppleRAID? Is the only way to do that to format and restore from a backup?

Looking to upgrade from Yosemite due to growing incompatibilities.

Thanks

Apple does not support booting from Apple RAID either.
You may be able to get it to work, but you cannot install security updates or other updates.

This is a problem that is not going away, as far as I know.

That's OK, I can update using an external then sync back if that's the only problem.

That trick works 100% with High Sierra.
With Mojave, it does not work with SoftRAID
WIth Apple's RAID it sometimes works.
With Catalina, it won't work with either.
