After waiting with my 10.12.6 iMac 27" 2011 with a RAID 0 boot drive for 2 YEARS, I've finally given up (since 10.14 doesn't support this Mac). I purchased a 1TB SSD and an 8TB HD and am installing 10.13.6 on it now. Ugh.
I think I have a workable way, over on the Mojave forums. I certainly didn't have any issues installing HS 10.13.6 or updating it to Mojave DP1 - I've outlined the process there.

Hi, just to tell you that the clean installation and update on an iMac 11.2Mid 2010 of 21.5 "with x2 SSD Kingston on RAID 0 16GB Ram has worked perfectly with the MacOS High Sierra Patcher Tool for Unsupported Macs, without APFS, only Mac OS Plus registered.
We have tried it as a resource since High Sierra does not allow to install natively in RAID volumes.

Excellent day! .



I’ve got a Mac Pro 5.1 with a Sonnet Tempo Pro Plus SSD card that has two Samsung 850 EVO drives on it. I’m really looking for support in High Sierra to be able to create a nice RAID 0 drive from them and make it the bootable system drive. It’s a weird omission so far. I’m guessing it relates to what Apple is doing with APFS. I was hoping the RAID 0 boot support might arrive when fusion drive APFS support arrived. I can be patient if I know it’s coming, but it would be very uncool to have bootable raid support not exist in High Sierra as it has in OS’s up till now. I’m not in the beta program and have no inside info on this, but any reassurance that bootable RAID support is coming would sure be nice.

What RAID cards are you using?
Is there any raid cards there with SAS connector and SATA connectors? So that one can convert the internal ports to SATA3 +make a extra RAID array?
