Q&A: El Capitan keeps beachballing

Q Although somewhat behind the curve, I know, I have just upgraded to El Capitan. It took me a great deal of messing around to get the installation to complete, and now that it is finally up and running, it keeps spending long periods, sometimes up to a minute, being unresponsive and showing the spinning beachball. I enclose some log excerpts. What is wrong and how can I fix it?

A The most important diagnostic step when you have this type of problem is to inspect your logs, using Console. Yours at the moment are full of entries such as:

09/12/2015 09:50:16.349 com.apple.xpc.launchd[1] (com.intego.VirusBarrier.bm_controller[30796]) Service exited with abnormal code: 4
09/12/2015 09:50:16.349 com.apple.xpc.launchd[1] (com.intego.VirusBarrier.bm_controller) Service only ran for 0 seconds. Pushing respawn out by 10 seconds.
09/12/2015 09:50:17.945 com.apple.xpc.launchd[1] (com.teamviewer.service[30797]) Service could not initialize: Unable to set current working directory. error = 2: No such file or directory, path = /Applications/TeamViewer.app/Contents/MacOS: 15B42: xpcproxy + 12028 [1353][19011403-4854-3CCD-9FCF-49C36302EB40]: 0x2
09/12/2015 09:50:17.945 com.apple.xpc.launchd[1] (com.teamviewer.service) Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

These indicate that you have old or broken installations of Intego’s VirusBarrier, and TeamViewer.

You therefore need to update them to versions which are compatible with El Capitan, or remove them. One good way of removing more complex apps like these is to run the original installer (or an uninstaller if provided) and engage its uninstall mode. If that doesn’t work, try downloading the latest version, install it, and then uninstall it.

You will need to plod on until your logs are clean and the beachballs gone. Further experience is in this article. Good luck!
