iMac Pro Imac Pro shipped mid June must reformat disk to upgrade OS Mojave!

[msironi]

Am I the only sucker who bought the Imac Pro in June, only to discover I cannot upgrade to Mojave without wiping and reformatting the drive? Really? In the end I will end up spending several hours of my time to fix a supply chain problem with Apple's $7800.00 machine and I have to jump through rings of fire? PS- no Apple store nearby to deal with.

Anyone else experienced this?

Why do you have to wipe and reformat your drive in order to upgrade to Mojave?

Just get Mojave from the App Store and install it. Make sure you backup first!

I'm told, that my machine shipped with OS High Sierra that cannot auto upgrade, owing to the new A
PHS file system. They have made an appt for me to have that done at a local dealer here in Medford, OR. If I can do without wiping that drive that would be my preference, but it does not seem possible from what i am told.

I think you have been given some wrong information.

Your iMac Pro file system is APFS which is also directly supported by Mojave. You can upgrade directly from High Sierra to Mojave, You do not need to reformat or wipe the drive. Read the information and instructions in the link I provided.

Make sure you backup before performing the upgrade!

Thanks for your input, I am grateful to dialog; when I go into the HD info the file system reads:
File system : Mac OS Extended (Journaled)
Am I correct and is Apple, that reformatting first is needed and then downloading Mojave, and then uploading the Time Machine backup?

"Mac OS Extended (Journaled)" (HFS+) is the old Apple file format. The new file format is APFS. The Mojave installer will automatically convert your current HFS+ to APFS. You do not need to format to APFS before installing Mojave. I would recommend letting the Mojave installer handle converting to APFS.

The Time Machine (TM) backup will need to be done in High Sierra before installing Mojave. It is needed in case you have a problem and wish to restore from Mojave back to High Sierra. You will not need to restore your old data using TM during the Mojave installation. The Mojave installer will install over your existing High Sierra system leaving your existing settings, data and apps in place.

BTW: The attached picture in your post looks like construction moulding??

Just download Mojave from the App Store, and let it auto run and all will be well.

OP:

Questions and a bit of advice:

Does the iMac Pro run well RIGHT NOW using High Sierra?
Do you have any compelling need to upgrade (i.e., software that won't run without Mojave)?

Unless you do, my suggestion is don't mess with Mojave yet.
Just "sit back" with your "good install of High Sierra", and wait until Mojave "matures" a bit more.

Some folks just have-to-have the latest iteration of the OS, just have-to-have the latest developer beta, etc., etc.

I stepped off the "upgrade train" a long time ago.
I "found a place where I'm comfortable" and where the Mac runs good, and I "stay there" a while.
It works for me.

Again -- re-evaluate as to whether you really "need to upgrade", or... not.

BTW, as others mentioned, if you DO upgrade to Mojave, the drive will be converted to APFS automatically as a part of the upgrade...

CoastalOR: many thanks for the advice...not that it matters, but why ship a machine that 3 months later needs to be fiddled with. Backing up now, and again, grateful for you input.
