MP 1,1-5,1 2012 Mac Pro 5,1 since upgrade to Mojave audio video app glitching

[MyClassicMac]

I have a:

Mid 2012 Mac Pro 5,1
2x 6core Xeon5690 3.47ghz
128gb 1333 ddr3
nividia geforce 120 and nivida force gt680 3 gb (non flashed for Mac)

boot rom version 144.0.0.0.0
smc version (system and tray) 1.39f11


I have been running just fine on 10.13 .6 High Sierra and was in the process of changing permissions on my 2tb ssd thought all was fine upgraded to Mojave and it started glitching in audio and video and crashing freezing spinning beach ball and I couldn't record in my Logic Pro daw without crazy pops and my mouse freezes clicking an app it bounces spinning beach ball or no reaction at all then pops to present time then crashes and restarts.. and low and behold my disk utility and terminal were not operational ......and I couldn't reformat my 2tb ssd because it wouldn't mount and I couldn't access it in disk util or terminal.

I ended up downloading a recovery program to get what I could off my 2tb ssd and then re-formatted an old hdd I had with high Sierra 10.13.6 and downloaded all my apps and have begun the arduous task of sorting thru 1tb off recovery ....bit by bit....

But alas I still have the weird quirks in High Sierra now??

So I did some research on here and came up with the following info
(from my extensions after reading that my extensions could be a problem)
here's what I found:

AudioAUUC version 1.7 date 7/31/22 (the date of my Mojave upgrade)
IOACPI Family version 1.4 date 6/21/18 (which most of the extensions are dated)
IOAudio Family version 206.5 date 6/21/18
IOGraphics Family version 519.23 date 7/31/22
IOPCI Family version 2.9 date 7/31/22
all are loaded all from apple

So can anyone explain to me how to fix the extension issues or what I can do to fix my dilemma
I'm low tech .....know just enough to get me in trouble
which is obviously why I'm here! LOL

Hoping for a solution my recording studio is inoperable as a result
not to mention my Mac being unusable in this state

HELP MR OR MISS WIZARD!

Cheers!

First thing, you can't use Mojave with a non-METAL/unsupported GPU and a METAL one. Weird glitches happen everywhere. The last macOS release that worked with dissimilar GPUs was High Sierra. Now you are using an unsupported and a supported one.

Second, try a clean install with an empty disk with just the GTX 680, install from macOS since you can't use a createinstallmedia USB installer with a GTX 680, and check if your problems still happen.

@MyClassicMac Also, please edit your post to remove your system serial number. This information can be used as part of a cyber attack against you and should not be posted publicly.

Post back to let us know how you do after following Alex's advice.

 

[MyClassicMac]

Thanks for the responses and advice
I am never running both GPUs at the same time I was using the 680 all this time on high Sierra ...I only used the 120 when I needed a boot screen it was not in the system at the time of this nightmare and I did start with a fresh install of high Sierra on a new disk I have since removed the 680 and have been running on high Sierra fresh install fresh disk the 120 gpu still glitching and shutting down and restarting did it while typing this and i did remove my numb serial numbersand the Mac os was not loaded from a bootable usb still same problems ...

If you have the same problems with a clean install, you have a hardware problem and not a driver problem.

My hopeful intention is to return to high Sierra and stay there if it works don't fix it but it appears that might prove very difficult this is the first time I've been totally stumped I do repair and restore on cams Mac airs MacBook pros and I'm aware of the no ncompatability issues of non metal gpu for Mojave thats why the 680

 

[MyClassicMac]

So are the extension discrepancies able to be aligned again or am I screwed on that one .

Did you started to diagnose the hardware?

Did you run AHT?

Checked the obvious things that fail like the northbridge heatsink push pins and the RTC battery?

This is not your problem.

 

[MyClassicMac]

and your suggesting I reinstall again on the 680 again then?

 

[tsialex]

Diagnose your hardware, then do a clean install of High Sierra on an empty disk and check if the problem persists.

 

[MyClassicMac]

can't get AHT to run tried both holding d and command d no go just loads regular

push pins look good
the battery I have not checked
and don't know if this matters but it always loads iTunes
immediately on boot never did that before

Northbridge is running at 120 farenheight and around 23 degree difference
between the heatsink and the diode
diode around 97 degrees

AHT is only present if your Mac still have the factory installed macOS install.

This Github article have the download links and how to install AHT to a USB key:

push pins look good
the battery I have not checked

It's a 10+ years Mac Pro, if the BR2032 battery was not replaced recently, it will be dead or dying.

RTC battery dead makes the Mac go crazy, timesinceboot variable is kept by the RTC.

and don't know if this matters but it always loads iTunes
immediately on boot never did that before

It's a forum convention to use Celsius for temperatures, no one outside USA will convert it to see if your temperatures are good. All forum posts that talk about expected temperatures are in Celsius.

 

[MyClassicMac]

sorry bout the celsius screw up thanks for the heads up ill follow your advise and do the usb trick you posted to get AHT and then post back after another fresh install of High Sierra from apple
Should I format guid partition extended journal yes?
and ill install a new battery

 

[MyClassicMac]

so Northbridge is running at 48.89 c and the heatsink is at 36.1

How to download and install macOS - Apple Support

Download and install current or previous versions of the Mac operating system on compatible Mac computers.

support.apple.com

Should I format guid partition extended journal yes?

You can use the command below, run diskutil list to see the correct inode disk name, then change the diskXX for the correct one:

diskutil list
diskutil erasedisk jhfs+ "Macintosh HD" GPT diskXX

and ill install a new battery

RTC battery should be replaced with a real BR2032, you can't use a CR2032 with the temperatures below the GPU.

so Northbridge is running at 48.89 c and the heatsink is at 36.1

Are you sure? These are temperatures for winter over the Arctic line For most people over the world, the heatsink diode will be around 72 to 75ºC.

heres my fan control specs

 

[MyClassicMac]

sorry bad habits my fan control specs properly

You are trying to kill your fans? Disable any custom control and let the SMC manage it.

 

[MyClassicMac]

I have reformatted a new ssd and did a fresh install of 10.13.6 and everything is working as intended now, thanks so much for the advice, spent hours listening closely to make sure no glitches ...mouse is operational and no spinning beach ball !! YEAH!!!!

As for the fans I run much colder than everyone I suppose , but my theory is cooler runs more efficient
I'm not a gamer I'm a recording and repair combo guy but the price of a new silent running fan is cheaper than other potential components that could fry . I had a Mac overheat and die with only SMC operating which is one of the reasons I use the macsfancontrol among others ..... so twice shy I suppose..... but if a new fan is all I need to fix ....I'm good.

Thanks again for your kind assistance you've saved my studio and repair space and I'm ever so grateful!!
back to recording!
CHEERS!

 

[MyClassicMac]

Also I failed to mention my settings for my DAW ie: buffer etc. were all out of setup for some reason
I adjusted these also for max performance..... operator error ?? yep that's me ......lol thanks again !!

But you can not buy a simple Fan, because apple is using non-standard fans.

If you run you Fans at 5000 rpm, you theory is far from reality.

If this was a Mac Pro who died on overheating, the most problems are thermal paste, IOH lock pins,
lack of cleaning or missing love.

 

[MyClassicMac]

My fans are fine good luck with your views i appreciate your understanding but in case you weren't aware i don't do or operate off opinions and my fans have been running like this for 3 years every hour every day ok so i appreciate your opinion but as far as i know this is a forum to assist others when they are stuck either hardware or soiftware and thanks to tsialex my problem was solved.........opinions don't get things done facts do....
i'll keep a post here to let you know when my fans blow up
three years and counting...... here we go.....
stay tuned....
CHEERS!

 

[TzunamiOSX]

I am an electrician and the extremely high speed increases the mechanical wear enormously. This only reduces the lifespan of the fans and if one fan fails completely, the components to be cooled could also be damaged.

I have used my Mac Pro for over 11 years with a bit higher fan speed (5-10%) and MUCH HOTTER parts (4 HDs, Titan X and now Vega Frontier, M.2 SSDs since the Samsung XP451 came out) than you, without any problems.

it's your computer, but i recommend a compromise between cooling and longevity.

In/Ex 1400 idle
1800 booster idle

if you want a cooler Nothbridge there are some cooling mods out there.
