How to install Git Extension on MacOS? I need to install GitExtension on MacOS, but I can't find any info about this. 

I found this link

https://sourceforge.net/projects/gitextensions/

after download I get compressed folder there is inside .exe file. I can't execute .exe file on macOS... 

So, maybe someone uses Git Extension on his laptop, please share an experience or maybe an alternative way should be used?
Here's some other Git visual front-ends for macOS you might consider:

Sourcetree (free)
Github Desktop (free)
Fork (free evaluation, $49.99 after that)
GitKraken (Free Personal)
