"your system has used all the memory allocated to applications" error with Photoshop on a Mac

Hi

I had the macOS error "your system has used all the memory allocated to applications" a few times this week when using the lasso selector for picture cropping in Photoshop.

Sometimes I needed to crash Photoshop and restart the computer (in case of side effects) before working on the same pictures.

It seems like selecting areas in a picture use a lot of memory and Photoshop don't free it, even after closing the picture properly.

2 problems :

- having the error and having to restart from zero after restarting Photoshop

- nothing save a selection to restore it by opening the picture again (or at least the software), preventing us to start from scratch and redo the same work for a random result (crash or not crash)

I join a screen capture of the problem showing the Finder window suggesting to close a software and saying Photoshop is not responding, and a screen capture of the same dialog box after closing the picture a time I could without closing the software showing the RAM still used by Photoshop.

I'm using Photoshop 26.2.0 on a macOS Sequoia 15.1.1 Mac mini M1 with 8Gb of RAM.
