MacOS – No longer update apps or use safari

mac-appstoremacospermissionsafari

I recently migrated my macbook 12" to a macbook pro (touchbar). I used the migration assistant to transfer a backup from the old mac to the new one. At first all was successful apart from a slight issue with the incompatible OS version between the two machines. (I had to update before migrating)

I am running Sierra(10.12.5 (16F73)) on the new machine. I am now facing a number of issues with the machine, I would guess its a permission thing. I think but cannot be certain that vmware fusion has something to do with the issue because it was the last program I tried to install from the old backup before seeing issues. (I had to kill the installation)

  • safari opens and appears to load a page, but just sits there – no matter what the url is. Chrome and Firefox work perfectly well and other programs do not have an issue getting an internet connection.
  • mac store updates do not work, when I click update on an app, I see: "We could not complete your update. Unknown error"

I noticed that the owner of my application (located at /Library/*) is as follows:

drwxr-xr-x@ 3 root wheel 102 30 Jun 2016 Safari.app

  1. Should root own these applications?
  2. How can I debug this issue with safari and the app store updates?
  3. Any thoughts what could cause behaviour like this?

So far, I have tried, neither worked:

  1. Repairing disk permissions using the 'first aid' tool in disk utility.
  2. Reinstall OS (restart, cmd+r, Reinstall OS)

Thanks
