Hi there,

 

Sorry that you're getting an error message in Photoshop saying that your Ram is full.

 

Which version of Photoshop are you using and what is the version of macOS you're running on your computer?

 

Please checkout this page on Photoshop Performance and optimize the app preferences to free up some memory:

https://helpx.adobe.com/photoshop/kb/optimize-photoshop-cc-performance.html

 

You can try freeing up RAM in Photoshop by closing all other images and invoking Edit > Purge > All.

 

Let us know how it goes.

 

Thanks,

Akash

Normally Photoshop never "runs out of RAM". It just writes to the scratch disk, which is what it will do anyway under all circumstances. But it does need a bare minimum to run.

 

Keep in mind that the "unified memory" in M1 is just a fancy name for a shared memory pool between the system and GPU. Under normal Photoshop operation, the GPU will eat up a very large chunk of that, perhaps as much as half. So in effect, you have about 16 GB for Photoshop.

 

And if there is a bug in the GPU driver (MacOS in this case), the GPU may keep taking more and more of that RAM as you work. That's known as a memory leak. It happens.

 

Memory leaks can also happen in third-party plugins, that's another rather common occurrence. If you have any installed, disable them and see if the problem goes away.

 

Plugins always run outside Photoshop's address space, and so require their own quota of RAM. If a plugin uses a lot of memory, that's less for Photoshop. Yet the error will most likely be reported from Photoshop.

 

And again, just so it's crystal clear: never set RAM allocation too high in PS preferences. In your case I would keep it under 70%.

Don't ever set RAM allocation to 100%!

 

That will quickly choke the whole machine completely. Other applications and background processes need memory too!

 

Always leave 2-4 GB for the rest of the system. The more RAM you have installed, the higher you can set the percentage. With 8 GB, set it to 60%. With 32 GB, you can go up to 80% or so.

I am having this issue as well. Very frustrating.

 

System:

macOS Big Sur: 11.2.2

Photoshop: 22.2.0

Adobe Camera Raw: 13.1

Macbook Pro: Apple Silicon M1: 16 GB RAM, 2TB HD (Plenty of HD free)

Photoshop Ram Setting: 10984MB (77%)

 

File:

ACR Developed CR2 @ 6720x4480 8bit

 

Once the file is developed in PS from ACR, the error comes when I try to save the image as a JPEG.

SOLUTION:

 

I had Media Encoder open after having just encoded some video. According to Activity Viewer, the aerender process was hogging most of the free system memory. Quitting Media Encoder seems to have restored order.

I don't use Media Encoder and still get the error message "Could not complete your request because there is not enough memory (RAM)".

It started with the previous (2022) version, in v.2021 it still works, but with the latest update (2023) I can't go back to v.2021 so I'm now completely stuck.
