My MAC OS X startup disk has no more space available for application memory.

Then you probably are running too many applications at the same time. You will need to quit those applications that you do not need to be running and see if you can free space on your system drive.

How much RAM has your mac, and how much free space is on your system drive?

See this discussion: MAC startup disc has no more space available for application memory.

If you click on the Apple -icon in the upper left corner of your screen and then "About this Mac", this will tell you how much memory your mac has.

To see how how much memory is used by your running applications you can launch the "Activity Monitor". It resides in the Utilities folder inside the Applications Folder.

To see the available Disk space select the icon of your system drive on your Desktop or in the Finder Sidebar and press cmd-I (OR "File -> Get Info" from the Finder File menu).

I dont know why yo9u are running out of space, but first let me explain what is happening.

Whne you run an app, it runs in RAM. let's say yuou have 2GB - 4GB of RAM.

OSX automatically swaps most of your programs, and unused portions, to disk files. This way you could have, say 10 GB of programs open, even if you only have 2G of RAM. 8GB would be on disk. OSX "swaps" parts in and out as needed.

So, from the words tyou tyuped, it sounds like your HARD DRIVE is running short on space to palce "swap" files.

How much space is free on your hard drive? Right click it, and "get info". It will tell you total, used and free (total-used)

Hope this helps.

The error essentially means your computer is out of memory. Most likely, some program you're running is buggy and has whats called a memory leak.

You can use Activity Monitor to learn which program on your computer is the culprit.

http://support.apple.com/kb/HT1342

Your startup volume is full. First, reboot. That will temporarily free up some space. According to Apple documentation, you need at least 9 GB free for normal operation. You also need enough space left over to allow for growth of your data.

Use a tool such as OmniDiskSweeper to explore your volume and find out what's taking up the space.

Proceed further only if the problem hasn't been solved.

ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To really see everything, you have to run it as root.

First, back up all data if you haven't already done so. No matter what happens, you should be able to restore your system to the state it was in at the time of that backup.

Launch the Terminal application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Terminal in the page that opens.

After installing ODS in the Applications folder, drag or copy — do not type — the following line into the Terminal window, then press return:

sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper

You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.

I don't recommend that you make a habit of this. Don't delete anything while running ODS as root. When you're done with it, quit it and also quit Terminal.

HI there linc, i followed your post on another mac forum... this is the first time i've done this so not sure if you reply or anything but i followed all your parts on the other forum and received the following notices... what do you advise?! sorry if you are bored of these! and appreciate it... quite proud i managed to carry out all the steps! ALSO NOT SURE IF FOUR IS RIGHT!!! SEEMS A BIT LONG?!

I recently bought a mac pro 3.33GHz 6-core 6GB 1TB and upgraded RAM to 20GB and installed a PCIe SSD 480GB and am running mountain Lion off my SSD.

My second day in I encounter this problem during an install of an update of Pro Tools . . . I don't understand how it can say there is no more space when the only app running is Finder and the installer and there's practically an empty SSD 400+GB on the SSD as well as loads of RAM?!

My mac crashed (this has never happened in my life time - nor this error) and i was forced to do a hard shut down by holding the power button down...I'm quite worried about this since it's barely 2 days old...

IMPORTANT - The interesting thing I noticed was just before my mac completely crashed I was able to go onto my SSD in finder and click 'get info' and for some reason the space available was only just on 300GB . . . which couldn't be correct. Upon hard shutting down and turning back on my mac pro - i noticed that the space available was back to 442GB and I restarted the install. Ie. Something must've occured that took up that 100GB of space that caused this error.

I have restarted the Pro Tools update and so far this issue hasn't reappeared. Any suggestions or solutions to avoid this - or even why it happened?

Many thanks

Matt

I have been dealing with this issue for the past few days. I have a 2.4 GHz Intel Core 2 Duo with 4 GB of RAM. There is approx 250 GB available on my 500 GB hard drive. I never got this message before about 10 days ago and now I'm getting it a lot. I am using Mountain Lion, btw.

I did a PRAM reset and that seemed to help for about a day - I thought I had fixed it....until the message popped up again. I'm also getting the rainbow ball a lot as well and things aren't fast or smooth until I shut down my computer. I'm not running anything important - just have safari, mail, and skype opened.

I think it's some sort of bug....maybe having to do with Lion or Mountain Lion??

Every time I've seen this problem, it's been this scenario: some third-party app or process is generating new swap files without releasing the old ones, so the hard disk gradually fills. At a certain point (either when the hard disk is almost full or when the system reaches some internal limit on how much space it can use) you'll get this "no more space available" message, and everything will slow down or freeze up. You can solve the problem temporarily by restarting (it has to be a normal restart, not a forced shut down, so that the system will clean up swap files) or by quitting the offending process (swap files will normally be released over the course of a few minutes after the process quits).

To identify the process that's swap-happy, open Activity Monitor and look for something taking up an inordinate amount of virtual memory (for comparison, Safari is usually the worst non-pathological memory hog, and it rarely gets above 500 mb). Quit that process and watch your memory slowly return. Then email the developer and tell them they goofed something up.

As many, many poeple have previously stated in this thread, just open Activity Monitor to discover which process on your computer is causing the problem. Please report back with what you find. Good luck!

I looked at the Activity Monitor with a fresh eye and found it : CalendarAgent was taking about 8 GB of virtual memory. When I deleted it, it reappeared as taking up 350 MB or so. However, now, within two minutes, it's already back to 1.81 GB and growing by the second.

I don't know exactly what CalendarAgent is, but it looks like there are other issues with it in Mountain Lion. All apps are closed, btw, except Safari.

What is CalendarAgent and do I need it or can I delete it for good?

(It's up to 2.40 GB now)

CalndarAgent syncs iCal with online calendars. The problem you're seeing seems to happen to a few people, and it looks like cobwebs (some stale network account settings left over from before the upgrade). The usual solution proposed is to delete and re-add your network accounts. See this blog for more details.

YES! ISSUE RESOLVED!!

I basically followed instructions to delete the Calendar completely from the library and then reinstall it. Now CalendarAgent is back to taking up just 60 MB of virtual memory (no change since yesterday) and everything is running perfectly -- fast and smooth.

I followed this guy's advice and it was perfect.
