Comment:

 Some of the messages may be unimportant or even desireable, e.g., no
 access to file://localhost/Volumes/Tor%20Browser/ (the still mounted Tor
 Browser dmg).

 This message from tor is strange:
  Dec 15 19:25:52.000 [warn] Got authentication cookie with wrong length
 (0)

 I do not know what
 `file://localhost/Library/Preferences/com.apple.ViewBridge.plist` is used
 for. And also there is a mention of
 `com.apple.inputmethod.EmojiFunctionRowItem`.

 I wonder if a third party system extension is installed, or maybe just a
 different keyboard layout is being used.

 It would also be helpful to know what the symptoms are from the
 browser/user perspective. Does the browser open a window? Does the
 about:tor page show that Tor is not working? What happens if you try to
 load a website?
