If I install High Sierra on my 2008 Mac Pro 3,1 with 2 x 1TB Samsung 850 SSD in a RAID-0 volume will the installation procedure detect that there are SSDs & will it convert the volume to APFS?

I know that I will need to use dosdude1's patcher to install High Sierra on the system.

That was me asking the same question over on that thread:) For others the answer is that dosdude's patcher doesn't convert any SSD boot drive to APFS unlike the regular installer where conversion is mandatory & automatic.

As an aside has anyone here installed High Sierra on a 2008 Mac Pro 3,1 with an SSD especially a RAID-0 boot volume?

I installed High Sierra yesterday on a 2008 Mac Pro 3,1 with a 256gb SSD as the main drive. Works great. Airport Extreme works, bluetooth works and the GT730 works as well with no extra setup

Did you convert to APFS?
 
I installed HS on a 4,1 flashed to 5,1. 480GB SSD as the boot drive was converted to APFS. All seems to work just fine.
 
I don't have HS installed on my MacPro3,1 at present, but awhile back when I did have it installed using APFS it booted and ran just fine.
I uninstalled it and went back to Sierra because of software issues with the 3rd party apps and APFS that I use every day

The 3,1 is a totally different computer than the 4,1.

The 2008 3,1 will not be able to boot from APFS.

I was really interested in knowing this however your claim that APFS boot volume doesn't work on a 3,1 is contradicted by the next reply. Does anyone have a definitive answer? Was the 5,1 firmware upgrade for High Sierra necessary for APFS boot?
 
Dosdude has an APFS patch for the unsupported machines in his installer, which makes boot these machines from UNencrypted APFS volumes. Encrypted APFS volumes can't used for booting ATM.

I have a 2008 Mac Pro (3,1) with an SSD as the boot drive running off of an OWC Mercury Accelsior S PCI-Express card. No RAID-0. Mine works great.

I have installed Mojave on RAID-0 SSDs on a Mac Pro 3,1. Using the installer even from dosdude1 patch won't work.
you have to install it first on a single hard drive/SSD then create the RAID with soft raid and clone the installed OS to the raid array. That way it will work as it should, but to update it you have to clone it again to a single drive, update the single drive and then clone it back. It is not very convenient method, but it is the only method of having SATA-3 speeds on a Mac Pro 3,1 without add-on card.

So DosDudes HS upgrade install for a 3,1 will not convert to APFS on an SSD by default? About to do this this week and want to confirm.
