SOLUTION

• Currently working for OS X 10.12.6
• Finder doesn't crash when .weblock is clicked.
• Safari is able to launch the url.
• However, Quicklook views .weblocs as plain text files, bypassing the web preview generation.

I also had this error on my system running Sierra 10.12.6 and the only recent change was the update to Safari 12.

Looking at the crash logs (In Console - User reports) certainly calls out the same things reported here as follows:

Time Awake Since Boot: 120 seconds

System Integrity Protection: enabled

Terminating Process: exc handler [0]

Application Specific Information:

XPC API Misuse: Release of last reference on a suspended connection.

Application Specific Signatures:

What this more or less tells me is that the Quicklook previewer is crashing when attempting to give you a preview of any weblink (in my case any *.webloc file).

What I had to do to fully fix this after trying all the normal things including rebuilding the spotlight index, trying safe mode, trying a new user, running disk check, checking the actual contents of the *.webloc files for corruption or malformed links, was to reinstall Sierra 10.12.6 by shutting down my system and holding COMMAND +R to "internet recovery" the OS on my machine.

Once the OS was reinstalled, full functionality was restored and I can now use spotlight as normal and include all items in the results with no further issues.

I am having the exact same problem too after updating Safari. It also happens if I select a link, and hit Comand + I. I just tried viewing contents of folder in icon view, but Finder crashed exactly the same way.

I noticed that Quick Look stopped functioning with links a while back, but Finder crashes are new.

Same system and Safari here. A work-around, not a fix: Disable preview column in Finder as follows.

Finder, View menu, Show View Options, deselect Show preview columns.

With this, the Finder no longer resets when I click a .webloc item. However, Get Info still crashes the finder.

One other note on this bug. I have two machines with the same setup, and one has the problem while the other does not. This just means there are more factors the just the system and Safari versions.

I hope this helps.

Ah! Icon and list view work OK for me with Show preview column enabled. But Quick Look does crash Finder, as does Get Info. So we are seeing the same bug. I did report to apple, as should anyone else who sees it, so they can hunt it down.

Apple taking their sweet time with this; for the time being reverted back to Safari 11.1.2 which at least doesn't crash the finder. On the downside it still doesn't preview .weblocs so I suppose we're just waiting for the next iteration which will (hopefully) remedy this (and will surely introduce other bugs). 😉

I posted this on a similar thread but I want to add my account here because the more Apple sees this, hopefully the sooner they fix it.

I'm also having this problem with Finder too--and it started around the same time as you after upgrading some applications. I've tried re-installing Sierra 10.12.6 and while it fixed the problem for a few days, just last night Finder began crashing again with basically any folder that had a URL file in it. Regardless of whether I was actually clicking on a URL file. And it doesn't seem switching users works either, it's only a temporary fix along with re-installing your OS.

It's happening to any URL file from any browser (I've tried all of them) too. It's refreshing to know it's not just a me problem, I was worried that I would need to get a new computer... I hope that Apple fixes this soon.

Hmmm..

I just downloaded Safari_12.0.1_for_macOS_Sierra_beta_4.dmg.

It's a Developer file and there is also a version for High Sierra too.

I took a chance and and installed it and it seems that the Finder crashing has been resolved.

Now, I could be wrong but clicking on any dot weblock files do not crash the Finder here anymore.

It would be nice if anyone else could confirm this.

You need a Developer Account, which I recall as being free, and just use your normal ID & password.

Note; the installation will overwrite your Safari 12.0. but it seems OK here.

A simple google of Safari 12.0.1 beta, should bring up the location of the files.

Still a little in dis-belief here and hoping it holds.

!!! EDIT !!! NOTE; It does not fix the quicklook problem, Finder still Crashes on dot weblock files.

I installed the Safari 12.0.1 beta and nothing changed. Still getting a Finder crash when doing Get Info on a .webloc file and when invoking Quicklook on same. Very frustrating. Feels like Mac OS X Public Beta 10.0 (which I have on DVD). That was 2000. This is 2018. C'mon, Apple. Fix this embarrassing problem now.

Yes, Get Info still crashes Finder on a webloc here also.

Quick look is also still messed up on weblocs.

I could not even SELECT a .webloc without Finder crashing.

At least I can safely select one now and even double click it and Safari opens it, so that’s better here.

Yes, Apple has a long way to go with this.

Is High Sierra having all the same issues ?

anyone?

I was really hoping that last update 12.0.1 would fix this issue, but Apple is STILL ignoring it. 😠

This is not cool. It makes me hate the Apple brand. I have multiple Mac and clients with Macs that can't upgrade to High Sierra for compatibility issues. This makes them not want to upgrade their machines, it makes them want to jump ship to Windows 10 I can't blame them.

FIX IT, APPLE. 😠

Quick Look .weblock files does not work!

The very same problem! It has happened for the second time. I had to reinstall the system, nothing else helped. Now, when updating Safari 12.0.2, it's even worse. The entire Finder will fall. Apple has the main purpose of the system, and if the basic things do not work, I'm annoyed.
