I have always been a big fan of SourceTree and told all my friends about this awesome utility but within the last year this piece of software has become unusable on Windows and now on macOS.
The latest version 2.7.2 (168) is slow and annoying on macOS Sierra now.
It's quicker using Git from a command line.
I've tried all the suggestion and they don't work. The only thing that has worked is reverting all the way back to version 1. Embedded Git Vs. System Git etc. etc.
Usually Atlassian products (JIRA and Confluence) are awesome but SourceTree is now a let down 
Please can you put a little effort into bringing it up to the same standard as JIRA and Confluence.
