Mac Pro (Mid 2010) & Mojave

[dickie001x]

Please forgive my ignorance/laziness/stupidity....but what do I need to do/buy in order to get Mojave running on my Mac Pro?
I have a MacPro5,1 (Mid 2010) with the following specs: 6-Core Intel Xeon 3.33GHz, 16GB Memory, ATI Radeon HD 5770.
I understand that I'll need to upgrade the graphics card...but to what? Links please.
Also, would my current specs suffice? (will I need more RAM, etc).
Thanks in advance!

Just to get it up and running. A GPU (video card) is all you’ll have to buy.

The top Apple recommended card, is the Sapphire Pulse Radeon RX580.

You will need to read up on the firmware requirements and nuances of the install yourself however.

As @crjackson2134 stated just get one of these, which is approved by Apple for Mojave. The rest of your hardware is just fine.
Sapphire Pulse Radeon RX 580 8G GDDR5 Dual HDMI/DVI-D/Dual DP Graphics Card - Black

In the mean time check what version of MacOS and boot rom you have. Latest versions: 10.13.6 and MP51.0089.B00

I'm in the same boat, but a dual processor 2.66 gHz with 128 GB RAM.

Do you have a link to these nuances? I'd like to know what I'm getting into before making the plunge!

This is the same? NewEgg is easier for me.

Does the original graphics card have to remain in my Mac Pro, or can it be removed once the Sapphire is installed?

Yes you can remove the original. You won’t get a boot selector screen but you will get macOS loading screen.

He MUST remove the original graphic card indeed. Otherwise the 10.14 installer won't run.

For GT120, it seems OK to boot 10.14. But only work AFTER 10.14 is installed, it still need to be removed when launch the installer.

But for 5770 / 5870. It seems these card will cause 10.14 can't boot.

I'm currently using a GTX 960 but have access to my stock 5770, will this patcher help me install Mojave?

Which Mac?

Which Mac?

sorry, I have a Mac Pro 5,1

 

[h9826790]

sorry, I have a Mac Pro 5,1

Shouldn't need any patcher

 

[giodelgado]

maybe I'm wrong but it seems I still need a supported GPU to install Mojave, it won't take the stock 5770 since it doesn't support metal and my GTX 960 isn't flashed.

You don't need flashed 960 to run the installer.

Of course, you will need to think about how to install / activate web driver etc after 10.14 installed.

So, just to be clear, I remove the OEM graphics card, install the Sapphire Pulse Radeon RX 580 and boot up in High Sierra. Run the Mojave installer and it should update the firmware and install Mojave. No other modifications to get a successful Mojave install?

Correct

 

[Cave Man]

Correct

Great, thank you very much!

 

[skullmonkey714]

Correct

I successfully upgraded to Mohave on my mid 2010 Mac Pro. Yet, I have a need to reinstall High Sierra again. Can I put the original video card back to get the boot screen and boot install high Sierra?

Boot screen is not required, but you will need a GPU that supported by HS.

Also, you need to create a HS USB installer. You can’t just run the HS installer inside Mojave.

I currently have a Sapphire Pulse Radeon RX 580 installed and need to do a clean install on a new SSD. From what I see, that card doesn’t support boot screens. Doesn’t the HS USB installer require the boot screen in order to install? Like you said, I can’t run the installer within Mohave.

 

[h9826790]

Doesn’t the HS USB installer require the boot screen in order to install?

No.

The installer itself has GPU driver. As long as your GPU is one of the supported GPU (e.g. your RX580), no boot screen required.

 

[h9826790]

If you really want boot screen, go for OpenCore. It can make non flashed AMD cards shows boot screen (and boot picker, depends on the settings) on cMP.

Like this (N.B. The Radeon VII in this video isn't flashed. In fact, I don't think there is any flash service for Radeon VII yet).

 

[skullmonkey714]

No.

Ok, that’s good to know. So how do I run the installer if not from the boot screen? I’m used to holding down option when turning the computer on and selecting USB. Then I do the whole disk utility thing, then install the os.

(btw...I’m really appreciating your help. I know I sound like a complete noob)

Remove all disks from your Mac Pro, keep just the createinstallmedia USB key installer for Mojave on the USB port and an empty/fully erased/new disk on SATA/PCIe.

When there are no bootable disks on SATA/PCIe/FireWire, your Mac Pro will boot automatically from USB. Since USB has the least priority when booting, you have to remove all other disks from your Mac Pro.

You don't need to do anything, around three minutes after you press power on, you have the macOS installer on your display.

Thanks for your advice. I’ll give that a try.
