Just updated to El Capitan - now running process "suggestd" all the time

I used your method. At the moment, it seems to have resolved the problem. I will research further. FYI The problem did not start until I opened Calendar on El Cap for the first time.

J P Garforth: Thank you for the suggestion. I followed every step carefully . . . to no avail. Still seeing the crash reports every few seconds. The only thing that works—for a short while, anyway—is to ignore the crash report and continue working. It pops up at nearly any occasion, even during shut-down. And I never had this problem before 10.11.5. Truly frustrating.

Cheers!

if you look in ~/Library/Logs/DiagnosticReports - do these all have a prefix of suggestd_2016- ?

In the beginning with this issue, just after the upgrade, I just deleted a number of folders (and already had some fixes from Mavericks) which cascaded out to other daemons; telephonyutilities and CallHistoryPlugin... all crashing, all writing logs, consuming cpu :-)

As an interim, to stop most of it heres what I used (as the user) to get a "quiet" machine, so I could work on the problem:

launchctl unload /System/Library/LaunchAgents/com.apple.suggestd.plist

launchctl unload /System/Library/LaunchAgents/com.apple.telephonyutilities.callservicesd.plist

launchctl unload /System/Library/LaunchAgents/com.apple.CalendarAgent.plist

launchctl unload /System/Library/LaunchAgents/com.apple.CallHistoryPluginHelper.plist

Mr Garforth: why, yes! Nearly everything in the DiagnosticReports folder begin with "suggestd_2016_ . . .".

I am going to unload the four items you named, and watch what happens. (I have been interrupted five - no, six - times while typing this. Simply unbelievable. And crazy-makin'!)

Watch this space!

Gee -- it's been five whole minutes and I haven't gotten a single crash report. I almost feel like an old friend is missing . . . naaah.

So now, I reckon the smart thing to do would be to slowly reload the four "helpers" one at a time, to find out which one to keep turned off permanently. (I'm technically declined, but willing to learn.) I think I'll wait a day or so between reloads, to see what happens when my spouse uses "the Hog".

Thanks a heap for your counsel!

Cheers,

Mr JPG: well, the messages are still appearing, and I am severely bummed. Didn't even turn on any of the four "helper" applications. It does appear slightly less often, but still shows up.

Thanks again for your assistance.

I am in Library but there is no folder Suggestions
