Q: Very slow iMac - have run Etrecheck

Have an iMac that has started to run very slowly. Sluggish and long response times (1-5 seconds) on many apps.

iMac (21.5 inch, Mid 2011)

Processor 2.8 GHz, Intel Core i7

Memory 16 GB  1333 MHz DDR3

Running OSX 10.10.3

All apps are updated.

 

Have run Etrecheck a few times. The iMac is slow even right after reboot. But it takes a few hours before it really starts to get bad. The check I ran below is after almost a full day since last reboot. And the list of processes and launch daemons that have been killed or have failed is looong.

I would be very grateful for advice on this.

 

Results of EtreCheck:

EtreCheck version: 2.2 (132)

    Hello can42,

    You obviously have a problem with kernel memory. I suggest you uninstall any software that has a kernel extension and try again. Make sure to use only vendor-provided I installers or I installation instructions. Never try to delete files by hand. Never use an app zapper. If you have trouble getting them removed, you may have to erase your hard drive and reinstall the operating system. Make sure to have a good backup before you start.

    I was afraid that might be the answer. I don't have the installers for several of the problem extensions.

    When you say 'erase drive' - is that because reinstalling Yosemite won't solve the problem?

    Yes,

    However, you can surely find the installers for most of that online. They should also come with an uninstaller (or check the developer's website for instructions).

    As you say it takes a while, this might not be a viable test, but try booting into Safe Mode. It takes a bit longer to boot, runs kind of sluggishly, and some things don't work. However, it should disable any of the kernel extensions and startup items.

    If it runs better, except for the limitations noted, then it is one of the plethora of system mods you have installed.

    Try safe mode if your Mac doesn't finish starting up - Apple Support

    Hello again can42,

    Sorry about the typo. I was on my iPad. I meant to write "uninstallers" or "uninstallation instructions". You can go to the support page for the various software and look for official uninstallers or uninstallation instructions. Unfortunately, you may not find anything. Reinstalling Yosemite by itself won't change anything. You have to remove the 3rd party software that is changing Yosemite into something else that uses up all of your 16 GB of RAM. I have no idea which extension is causing this problem.

     

    This is a very common problem for software purchased from outside of the Mac App Store. If you can't find the appropriate uninstallers, the only safe installation method is to erase your hard drive and then reinstall Yosemite. Some people may suggest command-line instructions or accessing hidden system files. Those procedures might even work. But I will not recommend them because I do not know what the end result might be. They could leave your system in an unstable state.

    Slow iMac discussion

     

    I’ve done some homework and managed to remove almost all the kermel extensions - the machine is still very sluggish and hangs for seconds at a time. So I’ve inlcuded aonter Etrecheck run below. I also tried to post a few  few minutes of System.log – when the machine was hanging and hardly responding. Lots a message that look bad - but I'm can't seem to post this - keep getting a message from the site saying the message contains invalid characters. Anyway around this?

     

    I can see from the EtreCheck that Safari is a problem – but I’ve been noticing that since the 10.10.3 update Safari is a growing problem on both this iMac and a MacAir we have at home, and a (2014) iMac at work.

    I have no use for the "etrecheck" stuff. Please don't post it in a reply to me. What happened when you followed the instructions in the support article linked to my last comment?

    I've been watching Activity Monitor for a while now - cannot see anything there on CPU. Most of the time the CPU load graph is barely showing anything. I don't know if it means anything, but when I look under the Memory tab it's showing that Safari is using 10-11 GB and kernel task is using 5 GB. Even as I was writing this post, the machine hung several times - I would punch several keys, and then have to wait 2-3 seconds for the letters to show up on the screen. But CPU load is minimal.

    At this moment it looks very much like Safari is at the root of your problems.

     

    You might try Disabling 3rd party Safari extensions

    Safari -> Preferences -> Extensions -> Off

    and restart Safari

     

    Also how many Safari windows/tabs do you have open.  Each one is going to consume resources.

    Hello Bob,

    The current version of EtreCheck includes a rough estimate of the number of tabs open. When you see a line like:

        1.22 GB    com.apple.WebKit.WebContent(5)

    it means that there were 5 separate Safari web content processes running. This may not be 1:1 equivalent to tabs, but might also reflect hidden activity.

     

    Otherwise, I think Safari extensions is the best place to start. The Google Earth Web Plug in might be a factor too, if can42 is using that.

    Please read this whole message before doing anything.

    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.

    Step 1

    The purpose of this step is to determine whether the problem is localized to your user account.

    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”

    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.

    Test while logged in as Guest. Same problem?

    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.

    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.

    Step 2

    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

    Please take this step regardless of the results of Step 1.

    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem.

    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.

    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.

    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

    Test while in safe mode. Same problem?

    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

    I have run both Steps 1 and 2. While logged in as Guest - everything worked fine. Let it run for a couple of days, no problem. Then logged in Safe Mode - again, let it run for a couple of days with no problems. Then logged into my account as ususal - and shortly after starting Safari the machie became very sluggish. So I disabled the 3 extensions (Zotero, Evernote, and Ember) I have and restarted - same problems as soon as I start Safari. When I check Activity Monitor while the machine is sluggish, there is very little CPU load - approx 95% idle; but the memory pressure is yellow, with Safari using 6-12 GB. Restarted the machine again - leaving Safari off, but using lots of other apps simultaneously (Outlook, Evernote, Word, Powerpoint, Adobe Pro, Photis, iTunes, iMovie etc) - with no problems. So it seems to be Safari related?

    Safari's excessive memory consumption is quite likely due the 'Internet Plug-ins' and/or 'User Internet Plug-ins'. Broadly speaking you should aim to keep the number of plug-ins you have installed to a minimum. Developers seem to love tricking users into installing parasitic plug-ins for other people's software and it often does not work out well for the user.
