“SafariPlugInUpdateNotifier quit unexpectedly” every few seconds

Are you running any third party AV-ware, Clean-ware or Optimizing-ware?

If so, they are not necessary and can cause all sorts of unexpected errors and other issues.

First off have a look at > https://www.apple.com/macos/security/

Then download and run EtreCheck Pro on your iMac and post back here with your Report.

i had success by deleting all instances (as permitted) of normally hidden files related to flash, then upgrading to the developer version of Safari, then rebooting; so far, several days without an issue…

Digging a bit further, I opened up Console and searched for the process... thousands of these errors daily, all the same pattern:

Jun 24 09:08:43 DMpro SafariPlugInUpdateNotifier[92189]: dyld: lazy symbol binding failed: Symbol not found: _PlugInUpdateNotifierMain

  Referenced from: /Library/Apple/System/Library/CoreServices/SafariSupport.bundle/Contents/MacOS/SafariPlugInUpdateNotifier

Jun 24 09:08:43 DMpro SafariPlugInUpdateNotifier[92189]: dyld: Symbol not found: _PlugInUpdateNotifierMain

Jun 24 09:08:43 DMpro com.apple.xpc.launchd[1] (com.apple.SafariPlugInUpdateNotifier): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.

I have a little time today to try and zero in on this. Will post back if / when I find a solution.

My approach would be to copy the item to somewhere safe and then move the original to trash and see what happens. -

It may be even better to have a bootable clone of your harddrive if somehow this experiment was not successful. However just putting the item back into place should suffice.

This way you really should get rid of the problem...

the Safari update this week seems to have cured the issue;

the moderators won’t let me discuss anything else, sorry

i got relief from installing the latest developer edition of safari & restarting the Mini

It came back exactly one week later. So I made a search with a utility called IFilex ant trashed every file with "SafariPlugInUpdateNotifier" in its name. Now I wait...

And I (almost) never use Safari anyway.

Doug,

what does it say in the second line of your crash report? Under "Path:"

It was happening here on a MacBook Pro late 2019. No relapses here as yet.

Here's the path for mine, as shown in Console's error report:

/Library/Apple/*/SafariSupport.bundle/Contents/MacOS/SafariPlugInUpdateNotifier

I've done a search and found 2 instances of the SafariSupport.bundle:

/Library/Apple/System/Library/CoreServices

/System/Library/Templates/Data/Library/Apple/System/Library/CoreServices

Inside each bundle, I found identical .plist files for SafariPlugInUpdateNotifier, which may or may not have anything to do with the crashing. Here's what's in the property list file:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>EnablePressuredExit</key>

<true/>

<key>Label</key>

<string>com.apple.SafariPlugInUpdateNotifier</string>

<key>Program</key>

<string>/Library/Apple/System/Library/CoreServices/SafariSupport.bundle/Contents/MacOS/SafariPlugInUpdateNotifier</string>

<key>LaunchEvents</key>

<dict>

<key>com.apple.fsevents.matching</key>

<dict>

<key>UserFlashPlugInModified</key>

<dict>

<key>Path</key>

<string>~/Library/Internet Plug-Ins/Flash Player.plugin</string>

</dict>

<key>SystemFlashPlugInModified</key>

<dict>

<key>Path</key>

<string>/Library/Internet Plug-Ins/Flash Player.plugin</string>

</dict>

</dict>

</dict>

</dict>

</plist>

You can see two paths referencing Flash Player - the root and user Library/Internet Plug-Ins folders. Mine are both empty, fwiw - I made invisible files & folders visible during this check. It is likely that this information is useless, I was just looking for clues.

UPDATE: I find it laughable that the Apple Recommended Solution in this thread is that the recent update fixes this issue. It most certainly is not fixed, and I'm current (Catalina).

UPDATE 2: /System/Library/LaunchAgents contains an alias to the previously-mentioned .plist file inside the bundle at /Library/Apple/System/Library/CoreServices

That is silly, as much of MacOS is these days.

I slow it down by letting the window open - somewhere in a corner of a screen.

Does not help at 100%, but is quite effectif.

If you can live with this kind of silly rubbish solution.

Hi,

I seem to have the same problem. This is after using Time Machine to migrate settings and users from 10.11.6 to 10.15.7

It started with Safari closed in that user account.

So please (1) what is the procedure that worked and (2) what do you mean by "SIP"?

No luck for me (Catalina, fully up to date). I've retyped this message 5 times, and dismissed this particular error about 30 times just trying to post here.

Restart helps for a bit, but something happens and the thing goes bananas.

What path is given in the second line of the error report which you are invited to send to Apple?

"Path: /Library/Apple/*/SafariSupport.bundle/Contents/MacOS/SafariPlugInUpdateNotifier"

However I could not find any such item. I do not understand the meaning of the *.

No parent process was given.

It seems to have stopped now here as well. I cannot recall whether I deleted anything. Sorry.

Thanks.
