I'd still like to see a memory usage breakdown. I still suspect it's the GPU that uses most of this memory.
It's very easy to make Lightroom call large amounts of graphics memory (VRAM). Just browsing thorugh a folder in Develop results in this with my 12GB GPU:
The interesting thing is that I have another machine with a 5GB card. It produces the same curve, only capping at 5 GB instead of 12.
In other words - it seems to use whatever GPU memory (VRAM) is available.
It should be said here that if other applications need VRAM, it's released and redirected. Nothing ever stops cold. It seems to be a highly dynamic system. And this is how memory is supposed to work. Free memory is wasted memory.
But there may be a timing factor involved. Maybe the memory needed is already allocated elsewhere, but in a way that can't easily be re-allocated.
From what I understand, granting these permissions has to do with access to the computer's storage, and nothing to do with memory. What do you think? Do you have this access granted?

I do grant that acess, because it allows the applications to work with both your files and its own files wherever they are located. (The reason Apple put that in is in case a malware application you didn’t know about is trying to alter your computer. But because we know about Adobe and that their software is not malicious, we grant it access.)
Granting access permissions avoids a lot of potential problems, but you are correct in your first sentence: The access permissions should not be directly related to the Out of Application Memory error. There might be some weird indirect effect we don’t know about, but on the surface, you are correct that storage permissions shouldn’t directly have anything to do with how working memory (RAM) works.
