Hi there,
SourceTree: 2.7.1 (it always fail to update to 2.7.6)
macOS: 10.11.6
Embedded-Git: 2.17.1
I found the most-closed existing thread to this problem at here - https://community.atlassian.com/t5/Sourcetree-questions/Sourcetree-on-OSX-not-working-after-enabling-Two-Factor/qaq-p/1037880. However, the solution didn't worked for me.
I'm trying to add a new account (Preferences -> Accounts):

Every time I click on 'Connect Account' it opens me the Git authentication window followed by two-factor-authentication-code - when I input everything the page shows me following, but never updates therefore:


Clicking on 'Click here' link also doesn't do anything even after waiting for a long time. The only option to the window is 'Cancel' and if I do that - no Account get added to SourceTree.
Please, help.
