Your System has Run out of Application memory

I upgraded to Mavericks from Mountain Lion, and I have been getting the error message "Your System has Run out of Application memory", and I am forced to restart the computer to be able to keep working.


I have been monitoring the Activity Monitor and I have not found a process that is increasing the amount of memory used. I have seen a proliferation of processes.


I have an iMac 27-inch, Late 2012 with a 3.4 GHz Intel Core i7 and 24 GB 1600 MHz DDR3.

iMac, OS X Mavericks (10.9), 27-inch Late 2012; 3.4 GHz i7; 24GB

I've been following this thread since just a few days after Mavericks was released and we experienced Mavericks take down a mini running OSX Server. It was running faithfully in our server rack. Nothing insatlled that was not official Mac software, for all the people that keep blaming other softwares, and it just kept locking up. We could restart and in 24 hours the system was totally frozen. Still no resolution or patch from Apple. We have it sucessfully running on a half dozen stations and they have not encountered the same issue. No clue why it is so random.

I have Mac mini Server (mid 2011) Intel Core i7 2.0 GHz (4 core); dual 500 GB (7200-rpm) hard drives ( 1st -354 GB free space; 2-nd 375 GB free space) ;8 GB PC-10600 (1333 MHz) DDR3 SO-DIMM (4x4); Intel HD Graphics 3000 512MB ; Mac OS 10.9.2 Mavericks.


1) I close all applications and start iMovie 10.0.2

2) I upload 2 hours long movie captured in HD 1920x1980 to iMovie Library.

3) I make a video 15 minutes long.

4) When I start to play this 15 m. video the message “Your System has Run out of Application memory” appears which forces me to quit iMovie.

5) I cannot transcode (FULL HD -> HD) 15 m. video because after 9 m of transcoding process “Your System has Run out of Application memory” appears which forces me to quit iMovie.

6) More - I cannot even sign in to my YouTube account to share videos because "Invalid Account Name or Password" appears in iMovie 10.0.2 for my absolutely correct ⚠ Account Name and Password.


The result - I cannot use iMovie anymore, it's useless! 😟


By the way I never had these problems using Mac OS 10.8 & iMovie 9.0.9! I even transcoded without any problems 2+ Hours long videos!

Correct me if I am wrong but I don't think anyone has mentioned iMovie in this thread before now.


It suggests that the OS is at fault (generically causing out of memory errors) or there is something else on your system causing iMovie to keel over.


KARX, I think you are going to get better attention if you create your own thread, otherwise you will have to sift through all the other (possibly unrelated) advice that comes and goes. Repost the info & link to it from here.


To resolve your issues you may need to post logs or EtreCheck reports which make the theads long & difficult to follow when everyone is hijacking with 'similar, but not the same issues'.

I have a Late 2013 iMac, 8 GB, with 10.9.3. I used Migration Assistant to move from an iMac G4 (the old snowball). I am amazed to see all these problems in this thread, as my iMac runs flawlessly with Safari, iMovie, Firefox, Numbers, you name it, Mail, even Mathematica. If I had realized how much faster and how trouble-free it would be, I would have bought it sooner.


I install plenty of third party software, but never anything that monkeys with the Finder, the menubar, that kind of thing. I don't even have Flash on it, or Chrome. When I look at Activity Monitor, my memory pressure is always green.

Yes time machine may have something going or adding to problem, I have had no backups, for a long time, it would run 45 min and then stop and could not finish because it was bussy? but now it's working, reseting pramitors I think fixed that for now?. I have only got out of memeory once but, you know spinning ball something is not wright or when typing the letters are slow to comeup on the screen!

You migrated from a G4?

That explains it - non of the old PPC apps would run on an Intel Mac 🙂


I think many other users are migrating data & apps from OS's that have seen versions from 10.4 - 10.8. It means the code could technically run (since it's mostly compiled for Intel), but uses methods that don't play well with sandboxing & new memory management. For whatever reason 10.9 is choking on old system extensions etc.


Every major OS has these teething troubles, I think the free nature of 10.9 & Apples pushy 'upgrade, upgrade, upgrade' mantra made more people jump without considering the state of their machines.


OS updates used to be something people prepared for (money & time is good for provoking thought & debate), now they just hit an install button & get annoyed when it fails.


Anecdotally, Mac users used to ask me "should I upgrade to [the latest cat]?", now they say "I updated to [x], why doesn't this work anymore?"

I think you should read that post again.

Doesn't sound like someone with Mavericks problems to me.
