SourceTree 3.1.2 100% CPU usage on Mac
Asked by emil.lewandowski:

This has been posted a few times times, since Dec 2017, and the first Question ([link](https://community.atlassian.com/t5/Sourcetree-questions/Sourcetree-2-7-144-High-CPU-load-on-Mac-OS-High-Sierra-10-13-2/qaq-p/686881)) has been closed and I don't know why, so I'm attempting to ask this again, to see if there's an update.

I am getting constant 100% CPU usage when running Sourcetree 3.1.2 on Mac OS Mojave 10.14.4

Any ideas as to why?

Thanks!

Here's a photo of the sample of my Sourcetree process. It seems to be increasing the load around the '_drawContentAtRow' instruction... Not sure.

body: I've actually grown to love the soothing white noise of my CPU fan coming on. Sure it will drain some of the useful life out of my computer due to wear and tear, but that's nothing compared to the blissful peacefulness I get from the calming whir of the CPU fan. So zen! Please don't fix it!

author: jasonwai
body: I was forced to use Sourcetree for a project the last 8 months, seriously, it cause performance degradation of my Macbook pro (high cpu usage), literally killed my battery (battery drain) (I have to replace the battery), cause overheating and potentially also cause the damage of my speaker (overheat?).

Atlassian, Why would a piece of software full load the CPU in the background? At least tell users why, and allow users to disable the features! (p.s. I have disabled all the "refresh when files change" features, still...)

Watching this discusson since 4 years now. It's a shame.

author: Matthew
body: Questions for all you peeps. I stopped using SourceSuck about a year and a half ago, but just stay on this thread to watch this epic fail persist with giggles of semi-disbelief.

So my question: Why is anyone still using Source Tree voluntarily? The app has been abandoned and just hurts your computer. There are better options, and better free ones too. Like [@jasonwai](/t5/user/viewprofilepage/user-id/997084) - you said you were "forced" to use it? Even if this were a team environment, GIT is application agnostic. No comprendo ;)

Genuinely curious here. Thanks!


author: wadesign
body: Hi Matthew,

And I think, we all are curious about what's the alternative? Are there any other apps working with bitbucket for Mac?

If there is a good alternative, i'll change today!


author: Matthew
body: Any GIT tool can read in a GIT repository. Doesn't matter if it's bitbucket-oriented. When you clone a new repository, just use the bitbucket URL in whatever tool you have.

I use GitHub Desktop, just to have a simple visual. You can use command line. There's some ever better paid tools - some people here have mentioned their favorites. Or just google best GIT tools to see what the latest verdict is...


author: Luboslav Horanic
body: To your question "why?" Matthew: Because this tool has another good features beside this annoying one, especially if you must use bitbucket for your projects and it improve your productivity with bitbucket. And yes, I use command line git for simple commands, but there are many cases where visual is a must to be productive...


author: jasonwai
body: [@Matthew](/t5/user/viewprofilepage/user-id/4223069) I was being a little bit exaggerated because I was very pissed. What I mean is I was on a tight schedule on a project, so I had no time to search for alternatives, so I kept using SourceTree without being too aware of it slowly killing my macbook and its battery. Until one day I find myself using a computer with constantly screaming fan, throttled cpu and swollen battery, and SourceTree is the one to blame.  

Now I am using Smartgit, some VS code git plugins and git command. I still use SourceTree sometimes, but I have to close it as soon as I finish using it.


author: Ralph Callaway
body: i really like a lot of the source tree GUIs, the interactive rebase is nice, i like the layout. i customized a lot of actions that were really nice. the search features and graph view work well. it's a measure of how annoying this bug is that i abandoned it

these days, i get by with the vs code git integrations plus git graph and git lens. they do pretty well, and have some features that are pretty sweet (like the ability to step through revisions in the file itself), and i've gotten much better with the command line. i still miss source tree, but my cpu sure doesn't


author: drawcode
body: Still a problem but look at it this way, the heat from your CPU can keep you warm during the winter.

Every once in a while when I have to use Sourcetree I forget to close after a commit and the room starts getting hot.

Thanks Atlassian for all the extra power you are consuming across the world. What is it doing mining crypto? smh.

When I use Souretree and Unity it is a tag team of CPU abuse.

I do appreciate the work that went into the tool and the tool itself. Though it does seem like a pay UI git client is the only way to make sure you don't have to worry about this, or github desktop or just old school git cli.

It must be one of those things that is so embedded that it is impossible to rip out or change and the person that wrote it is long gone.


author: lou-adrien.fabre
body: Haha indeed, definitely could thank Sourcetree for keeping my hands warm during these difficult winter times ![christmas-tree.png](https://community.atlassian.com/t5/image/serverpage/image-id/125903i64695DFDDC3B787A/image-size/large?v=v2&px=999 "christmas-tree.png")


author: Larry Weya
body: Been having lousy battery life on my week old 16" MBP just to realise it was all Sourcetree, have had to switch back to git commands and integrated GIT on VS code.


author: Bowen Fan
body: Ever since I encountered this problem, I've been resorting to using Git command line out of frustration. Now after months of practice, I've become a Pro in Git commands. Therefore I would like to thank SourceTree for implementing this 100% CPU feature which enabled me to upskill in my Git proficiency. Keep up the great work guys!


author: Steve Pascoe
body: My guess is this is something to do with excessively checking Pipelines. The spinner is rotating out of control. Probably something small to do with the animation. With these things its always something annoyingly small thats the cause. But yes i have been experiencing this CPU issue for a number of years now, might be time to consider an alternative.

comments: author: Jeremy Tredway
body: I can confirm that after removing a deprecated pipeline.yml file, the CPU usage went from 90%+ down to 0% when idle.


author: Steve Pascoe
body: My opinion is its almost certainly got to do with repos that have Pipelines builds associated with them. That or bitbucket repos in general.

I have two windows open now, one repo to AWS CodeCommit, the other to github and CPU is fine. If i open a bitbucket repo (that happens to be attached to Pipelines) i hear my laptop getting ready to take flight.

comments: author: Jeremy Tredway
body: I can confirm that after removing a deprecated pipeline.yml file, the CPU usage went from 90%+ down to 0% when idle.


author: wadesign
body: Hi Jeremy, hope this will work. where to find this YML file?


author: Andreas Ek
body: Perhaps in your repo ?


author: Jeremy Tredway
body: [@wadesign](/t5/user/viewprofilepage/user-id/3905338) If you have a pipeline file, it should be at the root of your repository. Look for a file with the *.yml* extension. Keep in mind, of course, that your project may have a legitimate use/need for your pipeline file. Thus, if you're unfamiliar with it, you should contact an admin of your project who does.


author: Dave Hale
body: My organization isn't using pipelines and there aren't any pipeline.yml files in any of our bitbucket repos; and yet the CPU still spikes with Sourcetree being the culprit. Any other suggestions?


author: nutmix
body: I have the same issue. SourceTree uses 40-100% of CPU on the most expensive 2018 macbook pro model when source tree is idle. It has been like this since I started using sourcetree about a year ago. The workaround for me is to open source tree, open my project, commit/push etc, then immediately quit source tree completely. If i forget to quit ST, then I soon know it because the fans start blowing. A quick trip to activity monitor and its source tree again.

You certainly cant use souretree if you are on battery.

author: Andreas Ek
body: Atlassian is so unbelievable uninterested to solve this issue affecting their users.

Are there som missing bits here? Don't they understand the issue?

comments: author: Matthew D
body: They've abandoned the project. This app is dead.


author: Arda
body: In my case, the culprit ended up being the file diff pane in History mode. A specific set of changes to a text file has been causing SourceTree's CPU usage to skyrocket and stay that way even though everything seems to be working fine otherwise (the diff pane displays the changes correctly and SourceTree is still fully responsive). Switching to other apps doesn't make a difference; CPU usage remains very high. However, selecting other History entries or changing the diff pane's "lines of context" setting to a different value fixes the issue immediately. The CPU usage is consistently high only when the specific history entry is selected.

I've tried creating a clean repo with a single file and just 2 commits that replicate the same textual changes, and got the exact same high CPU use issue. So this is not about anything else in my original repo, but something about the type/pattern of changes that are displayed in the diff pane. The only thing that stands out about the specific textual changes is that one of the lines before the change is rather long (290 characters).

If I'm not mistaken, simply changing the pane's size fixed the issue a couple of times too, but not consistently.

This is all on a Mac with an Intel processor. I've tried viewing the same history entry on a Mac with Apple's M1 chip and also on a Windows computer, but didn't get the same high CPU usage. But obviously there are many differences between the computers, including their screen sizes.

In short, if you're experiencing high CPU usage, try viewing different history entries and/or changing the diff pane's "lines of context" setting and see if that helps.

author: ture.friese
body: Upgrading to version 4.0.2 helped for my part. The high CPU usage is gone.

comments: author: Dirk Flachbart
body: Just upgraded from 4.0.1 to 4.0.2, unfortunately didn't solve anything for me, CPU still at 100%


author: wadesign
body: I'm running version 4.1.0, on MacOS Catalina.

And this bug is driving me crazy. Is there any idea if, and when this issue will be resolved?

comments: author: Ralph Callaway
body: it goes away as soon as you stop using source tree, i've switched to vs code's internal git tooling (along with the gitgraph and gitlens plugins)

the comment above this has links to older versions that don't have this bug (and don't support pipelines, which is fine since that seems to be the cause of the bug)


author: xuanxian
body: If the repo enable the pipe, The cpu will more 100%, I download v2.6.3 from to <https://sourcetreeapp.com/download-archives> , It do not support pipe, so can work well.

Hope the information can help.


author: Ralph Callaway
body: happening today with v3.1.2 (216) on mac os 10.14.6

checked console and didn't see anything in the logs per <https://confluence.atlassian.com/sourcetreekb/sourcetree-logfile-location-675384748.html>

the repo has a pipeline, haven't adjusted any options

checked open ports and files and ran a sample, nothing i could get anything from although i have know clue what i might be looking for


author: Ivan Parfenchuk
body: Also seeing high CPU usage on macOS 10.15.4 (19E287), Sourcetree 4.0.1 (234). Almost always 100%. Drains MBP battery too fast.

Turning off automatic refresh on file change did not help.


author: jacklin10
body: This is / was still a problem for me on MacOs even on version 4.0.1. I recently changed a few things that seem to have helped a bit that I'll share with the hope it helps someone else.

First, I had tons of repositories linked in SourceTree. I removed the bookmarks for all the repo's I am unlikely to touch any time soon. I have 12 in there now down from about 30.

Next I removed any setting that does any syncing or or auto refreshing.

In preferences "general" I unchecked:

"Refresh automatically when files change"  
"Check default remotes for updates every \[10\] minutes"  
"Load Gravatars for authors"

I did this yesterday, and I've been monitoring it today.  
I haven't seen the usually spikes to 100+% cpu usage. I say spike, which implies a brief time, but it sometimes it stays pegged over 100 until I close the app.

After the changes I'm seeing spikes between 14-25% cpu while I'm using the app.

You'll need to cmd+r more often to manually refresh, but i'll take that over the cpu problem until they can get it fixed.

author: bgannin
body: Hi [@emil.lewandowski](/t5/user/viewprofilepage/user-id/3008992),

That particular discussion devolved over time and was closed officially with [this comment](https://community.atlassian.com/t5/Sourcetree-questions/Sourcetree-2-7-144-High-CPU-load-on-Mac-OS-High-Sierra-10-13-2/qaq-p/686881/page/2#M25392).

We're tracking the performance issue *(as shown)* in relation to the build status column \[[SRCTREE-5306](https://jira.atlassian.com/browse/SRCTREE-5306)\]. Fixing that requires a bit of rearchitecting of the history view and is on our roadmap for a future update but I can't provide a specific timeline at the moment.

We apologize for the hassle and are keen to address it comprehensively.

Brian Ganninger  
Principal Developer, Sourcetree

comments: author: emil.lewandowski
body: Thanks for the update Brian, and thanks, of course, for the continued development of SourceTree, and for making it free for the public.

Looking forward to more news, in future.


author: Niklas Kolster
body: current beta release still has this issue


author: Kuba Domaszewicz
body: Can confirm


author: Matthew D
body: \[Edit Oct 14th\]

I'm done with SourceTree, unfortunately. And here's my brief experience.

It's been like this for several years. They've been saying it's on the roadmap for ages, and I don't think it is.

The solution by SourceTree is not to fix it, but to block user commenting because comments in the [original thread](https://community.atlassian.com/t5/Sourcetree-questions/Sourcetree-2-7-144-High-CPU-load-on-Mac-OS-High-Sierra-10-13-2/qaq-p/686881) have "devolved," as worded above by @bgannin.

SourceTree probably could offer a "disable expensive CPU history feature" option checkbox, as a patch while they rebuild the app, but I don't think they care to offer a patch or work-around?

I'm sure all the developers are nice people who put their hearts and soul into this product. But that didn't save Friendster when Friendster was abandoned by its users for performance issues (failure to scale).

So for the past two weeks, I switched over and have been using GitHub Desktop (also free). The switch took just a tiny bit to get familiar with, but I can leave it open all day with no CPU spiking at 100%! And it does the job quite well.

There's something bittersweet about this change... almost like when I left Firefox for Chrome after a Firefox bug they wouldn't (or couldn't) resolve. I'm a core fan of SourceTree, but the developer's seemingly blas? attitude and lack of priority for a HUGE DEAL BREAKING issue for us--over the course of not days or weeks but years--has left me disheartened. They've forced me to abandon them.
