Memory size ~100GB for Photoshop on Mac mini pro 2024

Since I have been using Mac mini 2024 with M4 pro, consumed memory size is getting bigger like over 100GB when I continue to use photoshop 2025. 
OS Sequoia 15.2

Mac mini pro M4 pro 24GB

Photoshop 26.2.0

 

I tried safe boost, update OS, but not much changed as Apple support suggested.

Lightroom classic has nothing abnormal.

 

Does anybody have this kind of issue and have implemented solution for this kind of issue?

So I just got back from an Apple Store and they round about suggested the same thing to me. I'm not crazy about putting down for a whole new computer but may have to do so.  Can I ask, what specific configuration was yours?  Mine is a M4 Pro Mac mini with 14‑core CPU, 20‑core GPU, 16-core Neural Engine, 64GB memory, & 2TB SSD.

 

i wonder if there is a correlation between specifics?


Mine has a 12-core CPU, a 16-core GPU, 24GB of memory, and a 512GB SSD.

However, I was able to find the solution myself after switching to a new Mac mini. The new Mac mini exhibited the same issue as before. I then contacted Adobe, and they suggested performing a clean installation of Creative Cloud and Adobe applications such as Lightroom Classic (LrC) and Photoshop (PS).

I followed the instructions provided in the link below:

This page might be in Japanese, but you can use a web translation tool if needed.

After completing the clean installation, the issue with increasing memory for Photoshop was resolved.

I also identified the root cause of the problem in my case. I had used Time Machine to transfer my Mac environment from my previous MacBook to the Mac mini, which caused issues with Creative Cloud.

When I initially bought a temporary Mac mini, I didn’t use Time Machine since it wasn’t my permanent setup. However, after getting my new Mac mini and restoring from Time Machine, the same issue reappeared.

So, it turns out that Time Machine was the culprit behind this issue.

Thank you for your participation, but I believe I have resolved this on my own.

So now we have another confirmation that a full reset of preferences fixed this problem. Several others have reported the same thing, so that should be the first thing to do for anyone affected.

 

I realize that others say resetting preferences did nothing. But it could be that you need to completely remove the whole settings folder for an absolutely fresh start, and that a standard reset may not be enough.

Same issue here.

I just got a new M4 Pro Mac mini with 14‑core CPU, 20‑core GPU, 16-core Neural Engine, 64GB memory, & 2TB SSD storage. Its been really great so far with one exception...

With a A fairly new virgin OS install and minimal third party applications other than PS & Creative cloud. I’ve been getting a message saying I’ve run out of system memory quite frequently when using Photoshop. I don't have this issue with my laptop using 16GB of Ram while working on the same files so I’m not really sure what the issue could be.  As can be seen in hte screen grab PS memory usage baloons to ver 200GB memory usage.  This happens slowly over time and does not matter wether files are open or worked on.  As long as PS is running it starts to happen.

Anyone have any insight or similar experience? Thanks!

    Recently I talked this issue with Apple support at Apple shop and they proposed to get new Mac mini to demonstrate whether this issue is happened on my Mac mini. I bought new same model at the Apple store and tried to install PS and LRC as I have in my Mac mini. I confirmed no issue with RAM for PS was not happened.
    I brought this result to Apple store and they accepted to replace the system board of my Mac mini.

    Based on this, I think I could say that this issue is related to Mac mini itself.
    I am still waiting for my Mac mini with ne system board arrive.

    Please try the clean installation.


    I Uninstalled and reinstalled Photoshop and Creative Cloud this morning about 5 hours ago.  After the reinstal I opened a modest PSD file did some minor edits and closed out the file.  Activity Monitor showed Photoshop as using about 3.6 GB of memory at the time.  Looking at activity monitor now it has balooned up to 51.57 GB since then.  Again, this is without any further files being open and only the app open for 5 hours now.  The reinstall of creative cloud did not seem to fix the issue.  Activity Monitor screengrab attached showingthe current status.

    If you have 24 GB installed, and Photoshop uses 95 GB, then that is obviously virtual memory - in other words, scratch disk.

     

    Photoshop writes a scratch file from the moment it opens (regardless of RAM), and this scratch file is expanded as needed. 100 GB scratch is perfectly normal.

     

    Raster image editing requires much more memory than any RAM you may have installed. There is no such thing as "enough RAM". Think of the scratch disk as Photoshop's main memory, with RAM as a fast access cache holding the most current data. The scratch file contains all history states for all open documents, plus overhead. If you're forced to work with limited scratch space, reduce history states.

     

    EDIT: note that the scratch file is not deleted until you close Photoshop.

    I forgot to mention one very critical thing regarding this issue.

    After the memory usage exceeds 100GB in Photoshop, a pop-up appears saying there's not enough memory, and then the Mac freezes. Also I can not shut down Photoshop as normal once memory is increased.
    As mentioned in another comment, the memory is consumed even when idle, so I'm not sure if the scratch file is related to this issue.

      Does your version of Photoshop consume that much memory when it is idle? What kind of images are you working on? The “Swap-section” in your Activity Monitor already shows that Photoshop has to push some of that used memory onto the hard drive as your machine can only provide a maximum of probably less than 24 GB of RAM. Can you show us your “Performance” section in the Photoshop preferences? Did you already try to uninstall and reinstall Photoshop?

        Yes, memory is consumed during idle (sleep mode) mostly.

        Since the memory size is consumed during idle, I don't think what kind of image is processed on PS.
        Regarding the memory for photoshop on setting is set as 70% of memory as your image. I can not show current setting, since I asked apple for service.
        I did re-install of Photoshop, but no change after that.
