I downloaded Tor and can't for the life of me OPEN it. I am on a Mac os Sierra 10.12.6 I have spent about 45 minutes with two people and it's just a dead, flat file - more like an image of a file than something that will open. Other files will open, so it's not my mouse or something. I also tried downloading from a different browser. Still nothing. I tried copying it into the applications folder and it's there, but still just flat and won't open.
Update your Mac to 10.13.2 (17C88) by opening the App Store and clicking the updates tab, and install any updates you see.
After your Mac is updated, right click on
a popup should show up. Drag TorBrowser onto the
/Applicationsfolder. click on launchpad and TorBrowser should show on one of the pages.
If you can not find it, open Finder and Click on
Applicationsand it should be in that list.
