The Early 2009 Mac Pro—also known as the Mac Pro 4,1—introduced Intel's Nehalem architecture to Apple's line of professional desktop computers in March 2009. The Mac Pro 5,1 used the same interior design but received further CPU updates in 2010 and 2012.

Mac Pro 2009 but 5,1 + Radeon 7950 no Mojave Metal - slow

Hi there

I've got Mac Pro 2009 flashed to 5,1 (to natively support High Sierra) - I've purchased Radeon 7950 because been told it is supporting macOS Mojave - and.... sorry - but got slow window animation "washed" white/grey colours like I've seen somewhere on youtube on unsupported Mac (I think 2008).

7950 is EFI flashed.

Mojave Public Beta 2

So what's wrong?

Your other problem may be that the High Sierra and/or Mojave has messed up your hard drive formatting if you have upgraded to an SSHD or SSD. I have the same machine, flashed to 5.1 with DosDude, but I only took it to Sierra. Running a 512 SSD as my boot drive.

Also MS Office 2011 will slow you down to a slow crawl with High Sierra and/or Mojave.

Go into About this Mac > System Report. Jump down to ‘Graphics/Displays’ section click on the GPU and look for the heading ‘Metal’ in my MacBook Pro 2012 system I see ‘Supported, feature set macOS GPUFamily1 v3’ Yours should say something similar if it supports Metal.

You may only need to update the GPU drivers to get it to work.

Fabulous. This really matters, now that Mojave is out.
