I got a blank screen every time the wizard prompted me to accept the EULA after the upgrade, so the app became unusable to me. Fortunately the 2.1 installer is available at <a href="http:&#x2F;&#x2F;downloads.atlassian.com&#x2F;software&#x2F;sourcetree&#x2F;SourceTree_2.1.dmg" rel="nofollow">http:&#x2F;&#x2F;downloads.atlassian.com&#x2F;software&#x2F;sourcetree&#x2F;SourceTre...</a> and after installing that I could get straight back to work. Even though they say they&#x27;ve have fixed this issue since I&#x27;m not very keen on upgrading anytime soon tbh.
