MacOs Monterey - run out of memory

This error message can have many causes:

Yes it’s totally possible it’s the hardware or the programmed OS. However more than likely in my experience it IS third party software installed, or external connected devices, and even the network it’s connected that can’t handle or allow the current process’ running.

I’ve also seen in the past on previous OS’ an issue with corrupted user permissions causing the error, or even Spotlight issues, both/all of which can be fixed.

My go-to’s are testing in safe mode (Which I know some have attempted) and in a new Admin user account.

These aren’t overall solutions, but more of an isolation steps(s). And are very revealing as to a cause.

Of course my first bet would be to quit ALL open applications, and open them in intervals, testing performance (Activity Monitor) after each launch and use.

Likewise, testing the issue with:

All external devices disconnected (Especially hubs, hard drives and monitors).

Testing with the internet totally turned OFF.

Activity Monitor is an awesome tool to use. And just because the configuration you have on your Mac either worked fine on another Mac or a previous OS, doesn’t rule third party apps out, any malfunctioning program can cause this error message and everybody’s Mac is configured and connected differently.

Worst comes to worst, you can install a new, fresh partition on your HD without erasing any data, reinstall the OS and see how it goes. If all works just fine, great! Then you can move your data to the new partition if needed, so there are many causes, but also options and results. Hope that helps somewhat.

I kinda regret having said that you can "quit the quilty process" as the consequences may vary a lot. Quitting mds tends to be harmless whereas killing WindowServer should harm the session a lot. Better just restart. And maybe yell at Cupertino..

Really don't know.

Also deleting Keynote and reinstalling can help as per other duscussion.

Your MBP does not have Terebytes of Memory. It has Terebytes of storage. Memory is indicated in the About this Mac window:

You probably have 8 or 16 GB of Memory, most likely 8.

Is that the latest version of Keynote? (11.2, if I'm not wrong)

Just another question: is it happening with just a partcular file or with any file?. The question is: are you maybe inconsciously importing many and/or large file into that doc?

Hello old toad, you remind me of my accountant, everything you've told me is absolutely correct, but it's not of much help.
