Got a 2023 Mac Pro (M2 Ultra) earlier this year, which forced me to upgrade my OS from Monterey to Ventura (and now Sonoma).
It started as soon as I got the 2023 Mac Pro and migrated all my stuff from my previous Mac, which was still running Monterey. The Mac Pro purchase effectively forced me to upgrade to Ventura, since the 2023 Mac Pro cannot run Monterey. Upgrading to Sonoma (at Apple's request) has only made the problem worse
Ever since then, have been experiencing a recurring problem that starts happening after several hours of uptime.
There is a whole cluster of symptoms, but the most obvious and common ones are the following:
It becomes impossible to edit pictures (HEIC, PNG, JPEG) in Preview. For example, I open a full size HEIC pic from my iPhone and I go to resize it down to 1000 pixels wide. Sometimes I get visual artefacts while the Resize dialog is open (note the grey boxes here):
And then when I press OK either I get a blank (instead of a small picture):
Or the picture is resized, but then it is impossible to save it. I get an error that says “The document could not be autosaved”:
And even if I try to revert the change, I get "The operation could not be completed”:
This does not just affect Preview. In this state, I find that when I open pictures in a third-party image editor like Pixelmator Pro or Affinity Photo 2, the app displays a blank (empty artboard) right away instead of the actual picture, even before I try to resize it.
Crucially, in Affinity Photo 2, there is a setting to disable Hardware Acceleration (under Performance).
If I disable it, quit and relaunch the app and then try to open a picture file, it works fine. Hence my suspicion that this is a bug involving hardware acceleration.
Another very common symptom in macOS when the cluster of symptoms starts happening is that, in various apps, buttons in dialog boxes become invisible which makes them impossible to read. This happens, for example, in the Notifications dialog box in the Podcasts app:
This affects regular buttons and also checkboxes, which disappear altogether when they are checked and reappear when they are unchecked. If I leave the dialog box open and switch to something else, the buttons reappear in their background form. They disappear again when I bring the dialog back to the foreground.
There are many, many other symptoms that start occurring at the same time, once the Mac is in this state. For example, screen recording stops working altogether. The Maps application also starts acting up. Zooming in and out no longer works, things start flickering like crazy, or going completely black.
I have, much more rarely, also seen video corruption in Firefox or Google Chrome, which can be alleviated by turning hardware acceleration off in these apps and relaunching them. Otherwise, quitting and relaunch the affected app does not help at all.
However, I have found that:
- Quitting a “big” app like Safari temporarily alleviates some of the symptoms. But when I relaunch Safari the problem starts happening again.
- If I quit all running apps, the problem disappears for a longer while. But when I relaunch things, the problem comes back after a while.
- If I reboot the Mac completely, then I am OK for a few hours, and then eventually the problems start reoccurring.
I have been in contact with AppleCare and have had to try all kinds of things. None of the things they have made me do have helped so far:
- I did a 100% clean install of macOS on a new volume. I need about 20 third-party apps just to be able to function for my work. But I did only reinstall the essential ones, and even that was enough to cause the problem to start happening again (within less than 48 hours).
- And, because of the Affinity Photo 2 scenario, and also the rarer video corruption in Google Chrome and Firefox, which are the only apps I know where hardware acceleration can be turned off, usually with dramatic improvement, it seems that it is a bug that involves hardware acceleration.
- I have run the hardware diagnostic on the Mac Pro and there are no reported issues.
That said, if it is not a hardware defect, I have yet to come across a single report of any other Mac user experiencing the same thing. I had been running the same software on a 2020 Mac Pro for years before this new purchase without any such problem.
Like I said, Apple has been unhelpful so far. Their requirement to completely eliminate third-party software and try to reproduce the problem is quite unrealistic.
I usually (successfully) help other Mac users fix their problems. But I am at a loss here. Is there really no hope? So I am now turning to this community of experienced Mac users. Maybe someone has some ideas.
