Question:

Question: iMac running slow, unable to determine why

Hi all,


Fairly standard thread about my computer slowing down. Key facts:


  1. The iMac in question is a work computer, with employer garbage software on it
  2. It's been slow since I got it, although it is getting a little worse
  3. It's been very lightly used (because it's slow, I use my personal laptop whenever possible)


The specific problem: I have frequent but irregular delays/freezes/beachballing with:


  • Opening apps
  • Opening pages within apps
  • running processes within apps (e.g., spell-check can take 4-5 sentences before it finally activates and changes a word)
  • Loading web pages
  • Logging in

Etc. I know the computer's four years old now, but (a) it's seen very light use, since I mostly use my laptop, and (b) it's been slow in this way since I got it.


The Etrecheck report is pasted below. Thanks so much for your help!

In my experience, two things can slow down any Mac (and PCs):


  • Anti-virus (Sophos in your case).
  • Google tools (I've seen it spawn multiple processes that take much resources).


I'd try the following:


  • Do a Time Machine of your Mac (as a backup plan) and save your personal file on an external drive;
  • Uninstall Sophos --> See if this helps
  • If not:

    Boot in Recovery mode (hold CMD+R on boot) and select the Reinstall macOS (this should not delete any user files, simply overwrite system files that could have been overwritten by other software). --> See if it helps

  • If this does not help:
    • Boot in Recovery mode (hold CMD+R on boot);
    • Erase your drive using Disk Utility;
    • Select Restore from Time Machine;
    • Reboot and see if that helps.
  • Last option:
    • Boot in Recovery mode (hold CMD+R on boot);
    • Erase your drive using Disk Utility;
    • Reinstall macOS from scratch;
    • Restore your backup of personal files;
    • Reinstall your apps.


Good luck!

Hi John, thanks for stopping by!


Booting in safe mode was a very strange experience. Two big things:


  1. Apps definitely load faster. Not as fast as they do on a new Mac (e.g. in an Apple store), but much better than normal. Evernote returns search results in under a second and loads note contents with a barely-perceptible delay, Chrome opens in a couple of seconds, etc.
  2. MAJOR graphics problems. Starting as soon as I finished typing my login password and hit "enter", the screen has been visibly flickering every time it loads a new graphic, with images stuttering (e.g. during the "bounce" animation for an application's dock icon when you open it) and image layers visibly loading in lines from the top of the screen to the bottom, etc. I've never seen any problems like these during non-safe-mode use.

During my research, I read something about "display RAM". Might that be the issue?


Thanks very much again!

Rule 1 of Macs is don't install junk.


Uninstall "Sophos". Use the Remove Sophos Anti-Virus program. It will be installed in your Mac's Applications folder, unless you moved or deleted it. In that case, follow their uninstallation instructions here: https://community.sophos.com/kb/en-us/122710.


(2) is normal because hardware graphics acceleration is disabled in Safe Mode.

Unfortunately, my version of Sophos was installed by my employer, and I can't remove it without their permission and the Tamper Protection password. I'll get in touch with them right away to ask about that.


I'll post back here if I'm able to get rid of it - shall I try something else in the meantime?


Thanks again =)

Google's Backup and Sync crashed, and Google products of all stripes are notorious for burdening a Mac. You can probably conclude that for yourself by using Activity Monitor, which will reveal Google to be the resource hog that it is: Use Activity Monitor on your Mac - Apple Support.


Google may be intrusive and burdensome, but unlike non-Apple "anti-virus" junk their products may actually be useful to you. You can find out for yourself by uninstalling it according to Google's instructions. If you simply can't live without Google you can always install it again, but beware that Google's automatic updating services can make it difficult to correlate poor performance to it. A Mac that runs perfectly well one day may run poorly the next, due to some update that Google pushed to your Mac unannounced.


Back up your Mac prior to making any changes to its file system. To learn how to use Time Machine please read How to use Time Machine to back up or restore your Mac - Apple Support.



Since they came to be in the traditionally virus-prone Windows PC environment, corporate "IT" departments are always enamored with "anti-virus" products, having been inured to their perceived need for a number of reasons, many of which are no longer relevant. Those products are categorically useless on Macs. When companies and institutions abandon their PCs in favor of Macs and iOS devices, their IT departments are usually decimated. As you might imagine they are never fond of that prospect.


Every institution in which I have personally involved in ridding themselves of Windows PCs have had their IT departments reduced by at least 90%, and in many cases eliminated altogether. The cost in terms of economic and productivity resources no longer wasted on them is incalculably high.

You might not want to remove the github stuff as suggested above, as it's likely been installed by your employer to work with munki, and it's certainly not adware.


My advice is take your mac to the sys admin / IT department responsible for administering your mac and get them to sort it out.
