Upgrading on 2012 MacPro

[choreo]

I have a 2012 MacPro with (2) ATI 5770 Graphics Cards and (2) 512 Samsung SSDs in an Apricorn PCI Card.

I am currently running El Capitain from one of the SSDs and the other SSD is empty.

I am thinking of maybe installing Mojave on the 2nd empty SSD so that I can start running the latest Adobe CC Apps.

What would be the procedure to do what I am considering? Any known downsides?

I would like to do a Clean Install vs Upgrade to hopefully get rid of some gremlins.

Thanks for the link, but I cannot even see how to upgrade to High Sierra? It does not show up in the App Store like my previous OS upgrades, so what is the procedure to installing High Sierra???

You are right - sorry. I saw that just as you posted this response.

Downloading now.

Still not sure however if Mojave will work with my ATI Radeon HD 5770 Graphics Cards?

It won’t... Again, you need to read the whole thing. You will have to upgrade your graphics card to one that supports metal.

Please don’t even start to upgrade your OS to anything new, until you fully understand. Some of the changes are BIG. Even High Sierra will convert your boot drive to APFS.

IF You’re not aware of what these changes do to your system, it’s best you don’t upgraded until your due-diligence is complete. If you haven’t preped everything, there’s a good chance you will regret you even tried.

Please read the thread I pointed you to, and please ask related questions in that thread for more complete answers that have been thoroughly researched and tested.

Good advice. Does not make much sense for me to dump any more money into my 2012 Mac Pro with a possible new modular Mac on the horizon. Think I will just wait as see if Apple comes through.

I have Mojave running on my MacBook Pro 2015 and it does not offer anything I really need that I can see. Only reason I was looking at upgrading my main Mac Pro is because Adobe's new CC apps launched this week require the latest Mac OS to install them, so I am stuck paying for Adobe subscription upgrades I cannot make use of (as I feared with their new subscription model).

Your system has plenty of horsepower for Mojave, but you will have to upgrade the graphics card.

With that updated to say an RX580, you will lose boot screens, your boot drive MUST be APFS, you will lose Bootcamp compatibility (if you need that), you will lose FileVault2 drive encryption (if you need that), if your monitor isn’t 4K you may be unhappy with fonts (no more sub-pixel smoothing).

I run Mojave on my 2012 cMP and I’m very happy with it, but you have to be prepared. Otherwise you MAY regret the upgrade. Look at the specs. in my signature. Mojave runs great for me.

I don’t have or require the Boot Screens, I don’t use FileVault2, and I have a workaround for BootCamp.

I was prepared and not disappointed. I upgraded my video card in anticipation for the Mojave release long before it was available to the public. It’s not expensive really, but know what lies ahead. Don’t just jump!
