After upgrading to Sonoma I keep getting "Your system has run out of application memory" messages

Recently (at the weekend) bought a new MacBook Pro (16" M2 16MB RAM) after running a 2015 Macbook Pro since new. Everything running swimmingly until upgrading to Sonoma OS – Now I'm getting repeated "Your system has run out of application memory" messages – asking me to Force Quit applications. Often I only have a couple of Applications running! (maybe Safari and Photoshop). The Mac locks up completely – I can't even force quit any apps, and have to restart the machine.

MacBook Pro 16″, macOS 14.0

It was probably a “rogue player” for me. I’ve recently ungraded from a 2015 MacBook, and basically copied everything across from the old machine to the new one. So there was eight years of old apps, fonts, downloads etc… in all proabbablity there was something in there that was conflicting.


I’ve since done a clean install (of Ventura) and am only adding in Apps, font and documents as I need them. So far so good, then in a week or two I might think about upgrading to Sonoma again, but I'll probably wait until version 14.01. Funnily enough it's not flagging up that there is an update available for Ventura for me, as (I think) it did before.
