OSStatus error 99999

The operation couldn’t be completed. (OSStatus error 99999.)

I get this error when trying to open certain applications downloaded directly from their official website using different browsers to download it multiple times. I've tried various solutions found in these forums to no avail. Can anyone help with this issue?

So to follow up. I finally erased my SSD after backing up and reinstalled the operating system. SUCCESS!! I am no longer getting the error and was able to open the applications that were affected by it. Thanks you all your help!

Uninstall Sophos per their directions , then run etrecheck again to see what chaff it left...

On CMM.


Delete these files & restart///


~/Library/LaunchAgents/com.adobe.ARM.***.plist


~/Library/LaunchAgents/com.apple.CSConfigDotMacCert-***@***-SharedServices.Agent.plist


/Library/LaunchAgents/com.barco.clicksharelauncher.plist


~ tilde indicates hidden Local Library

Apple hid the Users' Library folders...


  1. From the Finder, select the Go menu at top of the screen, and choose Go to Folder.
  2. In the window that opens, enter ~/Library, and click Go.

For how long?


Safe Boot, (holding Shift key down at startup).


Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.


If that doesn't do it, we might find the problem with an etrecheck report.

EtreCheck is a FREE simple little diagnostic tool to display the important details of your system configuration and allow you to copy that information to the Clipboard.

Pastebin is a good place to paste the whole report if you capture the URL while there…

Whew, they've changed pastebin & made it harder, but after pasting in, click Create new paste button, then Embed button, then copy the URL...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...
