MP 1,1-5,1 another trouble installing High Sierra thread

[machenryr]

Hey! I have an older boot drive that has OS Sierra on it. I want to put it in an external enclosure, but of course my main boot is Mojave and won't see the Sierra drive. So I'm trying to upgrade the Sierra to High Sierra. The MacPro 5,1 has already been brought up to speed, as far as I know, in terms of the metal GPU and the bootRom has been done in order to upgrade to Mojave. So I figured bringing the external drive from Sierra to High Sierra would be a piece of cake. It uses the updated MacPro.

The installation kept quitting. Saying there was an error, please try again. Then I saw there was a software security update I hadn't installed. So I hit install and it's been stuck on restart. LOL.

AS far as I know, after many searches, there are no other High Sierra install applications on my drives.

Are there other hoops I need to jump through to upgrade the Sierra spin drive to High Sierra? OH, another question - will the High Sierra drive be recognized by the Mojave drive, or will I also have to upgrade THAT one to Mojave?

Thanks!

I get this over and over. All apps are closed.

if you have HS installer downloaded before oct 29 > reload it
or change your clock before oct 28

Wow. Huh? I think I downloaded it this morning from the App store. I'll try changing the clock to before Oct 28. Thanks!

Let us know how it goes.

Mojave should see the drive, so I wonder if it might be faulty. Did you try using Disk Utility to check the drive for errors?

I will. No, I'm pretty sure it's documented. Several months ago I saw this problem. I came here and found out that it isn't seen - as a known thing. I have several back up drives until I decide to fully transition to Mojave. If I'm on Mojave and I want to start up from my Sierra drive, I can do it. But if I've booted from the Sierra I can't see the Mojave drive, but I can see the High Sierra drive. So I have to boot up to HS and THEN boot Mojave. Slight pain. But this is ONLY if the Sierra drive is in one of the internal drive bays in the MacPro. It won't BOOT if it's in an external enclosure.

I'll let you know!

This makes a lot more sense! You said the opposite in your original post:

my main boot is Mojave and won't see the Sierra drive

But it seems you meant Sierra can't see the Mojave drive, which is correct behavior (that is, Sierra can't read APFS drives). Good luck with the upgrade.

I realzed this as I was typing my previous response!

start from the sierra drive and look at the partitionmap in diskutilies
i think it is an updatet system and the drive has apple partition map
instead GUID partition

maybe you can install highsierra direct from this drive,
but if the APM is the problem it will fail because convert
to APFS need a HFS+ partitionmap to change
