SourceTree 4.0.1 super high CPU usage on MacOS

I've seen this problem reported since SourceTree 2.7 and I can't believe it's still not fixed in 2+ years, therefore I hope I'm doing something wrong.

Bug Description:

SourceTree consumes all of MacBook's CPU while doing exactly nothing.


Repro Steps:

1) Open SourceTree

2) Open a Repository (BigBucket connected - I don't know if this matters?)

3) Do exactly nothing

4) Watch the CPU consumption to grow and grow above >200% - untilt the MacBook's fan goes crazy

I had been dealing with this issue for way too long and and finally found a solution.


1. Close SourceTree

2. Install Github Desktop -

3. Never use SourceTree again


It's unfortunate that this issue hasn't fixed by Atlassian. SourceTree is a great app but this is a deal breaker. I can't continue living in fear that my idle Git client is going to start using 120%+ cpu every time I have it open (aka always).

I was having the same issue forever.  I found this:

Read down to the part about Keychain.  I had a bad account in my keychain, and it was causing these exact CPU issues.  Removed the bad entries in Keychain, and now everything is just fine.

Thank you @jfjcn I appreciate your answer. I resigned on using SourceTree about a week ago (I'll describe my reasons below) but I still have my old account, I will try your tip just for completeness sake.

I have the same issue with Version 4.0.2 of SourceTree. But the hint with removing entries in Keychain doesn't work for me.

Having the same issue (version 4.0.2).

Did remove all entries related to source tree. But it does not work for me. 😅

It worked for me! It seems to be related to the issue because my cpu got to 95% after I entered a wrong credential for a repo.

Ok folks, I solved it in an unusual way, not suitable for everyone but wanted to share.

I got super-frustrated about Atlassian because there is no way to contact their customer support and Atlassian stuff is absolutely unresponsive in this forum.

A week ago I stopped using SourceTree and shifted to Visual Studio code with Git History plugin. It works excellent for me. Not only have I solved my CPU problem but I also got some more features that I've been waiting for for long-long time, such as:

  • Viewing Git history of one single file
  • Viewing Git history of all files in a specific folder

Thanks to the community driven nature of VSCode plugins it's much more actively developed than the abandoned SourceTree.

I think it is a no way back for me.

I'm stuck in my ways and I don't want to learn a new Git client right now :-). It seems that a workaround is to hide (Cmd-H) SourceTree, and the CPU usage quickly drops to 0% while hidden. Not ideal, but it soon becomes muscle memory when you stop actively looking at the SourceTree window.
