Your model of MacBook Pro  has at least 16GB of memory. Therefore, it will meet all of the systems requirements for full GPU acceleration support. However, the GPU self check when launching LrC has probably detected an issue and disabled all or part of GPU acceleration. This is not unusual after an OS update. Fortunately, it's relatively to fix this.  You need to use 'Finder' to navigate to the below location  then delete the contents of the folder. LrC will recreate same when it relaunches. All

I'm a Windows user, so I can not advise you of any remedy. On my Windows 11 computer LrC indicates limited support for GPU acceleration, and there really isn't any setting to change that other than to turn it off which I have not done. I don't know if there is a driver update you can install on your Mac that might remedy the situation. I have never used a Mac.

The macos cannot update the driver. Only the lightroom software can be updated to fix the error

Without you stating specifically what the issue is, I doubt anyone can help. "Limited availability" tells me nothing. Please describe the issue in detail.

My mistake, I apologize. I forgot about that fact about the Mac. That's what I get for chiming in on something I have never used. "I think" what the OP is referring to is this:

It is normal for the auto choice to default into "limited acceleration" if you do not have a lot of memory on the gpu. The m1 chip uses shared memory with main memory. If you change from auto to custom, does it show that it uses the gpu for display and for image processing but is disabled for export? That is typical for this circumstance. You can manually override the last one and enable it for export but it probably won't make much difference so is fine if you keep it on auto. If the custom shows it only uses the gpu for display, that is a problem as you really want the gpu be used for image processing and could be a bug. There is no such thing as a GPU driver update for m1 macs as they use a GPU embedded on the main chip and not on a separate card, which gives a massive speedup of memory access and other operations. But it does mean that driver updates come with the operating system automatically and you don't have to go to somebody else's ebsite to download a driver.

Read here for the explanation:

You'll see that to get it enabled for export, you need 8GB of GPU memory or 16 GB of shared memory. If your M1Pro is only the 8 GB model (amazing they actually sell those but I digress), it will not enable the GPU for export automatically.
