I manually deleted all preferences in my preference folder in my library folder..  other than that I'm not quite sure what else or how to find any others.   I'm not loving the idea but I may have to do a fresh virgin install of the OS and Creative cloud to test this out.  Sigh... ... View more

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. ...

Interesting.  I do use Time Machine to back up but I did not use it to restore/set up my new Mac mini.  I just manually copied my documents and lies over.  I don't believe I copied any preferences ether but will have try a complete reinstall of creative cloud and report back. ... View more

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? ...

Some further RAM & Disk usage stats.  Hopefully someone can give some further insight? ... View more

Im not sure how feasable it is for me to purchase a whole other Mac Mini to compare.  Looks like I may have to make an appointment at an Apple Store though. Oy! ... View more

Thank you for your response.   I understand that a 200 GB scratch file is normal.  Ive just never had it freeze my system up and give me an error stating "Your system has run out of application memory".  Even with systems that have far less specs.    In regard to PS preferences for memory allocation I have tried to adjust that but it doesnt seem to make any difference. Eventually it ends up causing the system to lock up and run out of application memory even if PS is the only application running.   I do have  1.03 TB available of 2 TB drive for my scratch drive so the 200GB really shouldnt be an issue I wouldnt think either.   Im unsure as to what type of breakdown to provide but happy to do so. In the activity monitor app in addition to the memory section I just posted there is a "Disk" section that has several data stats in real time for all of the machines processes and Applications etc... ...

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!   ... View more

Also worth noting that I have plenty of free hard drive space (Approximately 1TB used on a 2TB drive) and the OS and all apps are up to date. ... View more
