  • Let's gather AMD driver list collection

I have been looking for an option to disable dithering on AMD Radeon graphics cards on Macbook Pro 15''/16''.

To provide the common solution, I would like to collect the list of AMD drivers being loaded

If someone has such laptop, please run the command:

kextstat | grep AMD

and share the results. My macbook pro 19 15'' has such list:

These are 2 drivers from 2 iMacs , I know that laptops use a different methods to manage the discrete GPUs but I post them anyway in case if you can find something interesting for desktops too.

It's interesting why community is not active on this topic?!

…maybe almost everyone uses M1/M2 based laptops.

    NewDwarf I think most of us are not able to use most of the Apple products.

    In my case I use without any symptoms: Iphone X and Ipad air 2

    Can't use: macbook air 2018, MBP 16" 2019, Ipad pro 10.5, ipad 10th and iphone 14 pro.

    Next week I will try to buy an MBA M2 and try to use it with the better display app which seems to help. If you need any info from the terminal let me know.

    But what is your situation? Can you use their recent products?

      Lauda89 …same. I cannot use most of modern Apple products.

      My phone is iPhone SE 2022, my laptops are Macbook Pro 2018 with 4TB 13'', Macbook Pro with 4TB 2019 13'', and MacBook Pro 2019 15''. All these devices are PWM free and without dithering.

        NewDwarf can you use all three macs? or do you have symptoms with all of them? Does it improve the situation with your commands to eliminate dithering?

          Lauda89 Yes, I use all three devices. They don't require any additional actions to disable dithering. I would say they work out of the box.

          Unfortunately many of us purchased and return/resold MacBooks (and many other devices) because we couldn't use them 🙁.

          NewDwarf I use Windows. Altough I could use/buy a Mac if bootcamp Windows would also work with no strain.

          I have quite a number of Macs, but the only ones with AMD GPU's:

          15" MacBook Pro 2016, currently running macOS 12.6.2 (Note: Laptop has always caused me strain, since I got it back in 2017)

          Mac Pro 2013, currently running macOS 10.14.6 (Note: Desktop has been one of my "safe" devices, for 8+ years, never causing me the slightest strain, till it went bad this past August… suddenly causing the same strain/dizziness/brain fog as most modern Macs)

            Lauda89 - Unfortunately, no. I had the Mac Pro fixed on Mojave 10.14.6, and was making sure not to install any macOS Security Updates, and one day it just suddenly went bad, causing the eye strain.

            Since then I've spent months trying a variety of approaches, either:

            • Reverting the Mac Pro to a variety of Time Machine backups; going back as far as a 3-year old backup
            • Erasing the internal drive, and installing fresh copies of Mavericks 10.9.0 through 10.9.5, Sierra 10.12.0 through 10.12.6, High Sierra 10.13.6, and Mojave 10.14.0 through 10.14.6
            • Using macOS app BackupLoupe, comparing my Time Machine backups of the last good backup (when it caused me no issues) to a backup shortly after it went bad, in trying to discern which specific config files could have changed
            • Disabling/swapping various kext's; some of which would disable hardware acceleration
            • Examining/testing with a combination of EFI Firmware updates - where booting from an external drive with a different macOS version installed than the internal drive, to see how the older or newer firmware (installed as part of the macOS install) behaves in comparison to the other macOS version on the other drive
            • All the other standard macOS-specific tricks; PRAM/SMC resets, disabling font smoothing, etc

            And unfortunately, no matter what I've tried, I cannot get this desktop back to its original state…. where it caused me absolutely no strain for 8+ years, connected to my trusty old (DVI-based) 23" Apple Cinema display, from 2006.
