Usually my Mac performs pretty comfortably but for the last hour or so it's been almost unusable. When I type it takes a few seconds to actually display what I've typed or just beachballs for a little while. If I try to open a new tab in Safari it takes about half a minute to actually appear.

When I opened Activity Monitor to see if I could work out what was happening "softwareupdated" was taking 100% CPU and Memory Pressure is in the red. I tried opening the App Store application to see if that would tell me but the application just opens but won't draw any content.

enter image description here

I didn't tell my Mac to update anything, and the App Store app seems useless right now, so how do I find out what is it doing that is causing this?

  • mine was busy updating Pages, Notes & Keynote in the background [for no real apparent reason as they were supposedly already up to date], whilst I was trying to get it to find 10.10.4 & iTunes. I waited it out then rebooted. All went back to normal & I got both the OS X & iTunes updates then.

    Also - check what you have set in System prefs > App Store - there's a whole bunch of background update options in there.

  • I had the same issue. CPU 100%. Just kill that process in Activity Monitor. Then check for update, it will work as expected.

If you open the Console application I believe it defaults to "All Messages" which might not provide any useful information.

However if you open the Console application, then open the "/var/log" option at the bottom of the left-hand source pane you should find an entry for "install.log". If you select that you should see some information on what softwareupdated is actually doing, or trying to do, to your machine.

I had the same problem. Fixed this way:

  1. go to system preferences
  2. click on app store
  3. un-click "Automatically check for updates"

Problem solved!

  • Is that really fixing it though? Isn't that like taking your car to the garage cause its making a funny rattling noise while you drive and the mechanic saying "The way to fix this is to stop driving your car and take the bus instead."? Jan 5, 2018 at 21:51

I solved this by rebooting and installing OS X Yosemite 10.10.4 Combo Update.

For me kill -9 softwareupdated led to a requester to reboot the mac being shown. After the reboot the installation started. Nothing seems to be broken at the moment, but now I am a bit scared.
