Error “Your system has run out of application memory.” on new MacBook M# Pro with 36 gb Ram

[kcslagle]

I'm hoping someone has an easy fix for me. I am having a problem on my brand new MacBook M3 Pro with 36 GB RAM when I run Lightroom. It's happened twice. I will leave Lightroom open and come back to it the next day and my laptop will have the “Your system has run out of application memory” error. The first time it happened I did have multiple Adobe apps open, the second time I only had Lightroom open (+Chrome, Mail, etc). 
My laptop is M3 Pro / 36 G Memory / Sonoma 14.6.1

I've only had the laptop for a week and I doubled the amount of RAM I had before so I definitely wasn't expecting any problems with the memory! 😞

Do you have sync to Adobe Cloud enabled? I ask because there are many users who experience excessive memory use when sync is enabled. If you do have it enabled, then try Pausing to see if that helps. Normally it does.

I did have it enabled but turned it off. I think that could be it. Fingers crossed! Thanks so much.

Hopefully that was the cause. Adobe is working on fixing the sync/memory issue.

In general, 36GB for Lightroom Classic on a Mac is a good amount, more than enough for most things. (I have 32GB)

Pllease keep us updated on whether it helps.

In the meantime, someone more knowledgeable on sync issues might provide a fix for you.

I turned off the sync with Adobe Cloud and that seems to have done the trick. I haven't had any problems. Thank you!!
