Q: Magic Mouse doing "swipe back" when trying to scroll down post-Yosemite

Yeah, it's a problem in both browsers for me. Chrome is a bit more severe. The best thing to do is switch the 'swipe between pages' setting to 'swipe left or right with two fingers'. That solves the problem for me, but I can't use two fingers to swipe between full screen apps. Then again, I never did.

Yes - this is especially infuriating because so many sites now have "endless scroll" where more content loads when you get to the bottom. Say you're several "scrolls" deep into a site, and the mouse goes BACK instead, you have to start over at the top.

Does anyone know if there's a fix - perhaps third party mouse gesture control app?

I use the 2-finger swipe all the time because I run VMs in their own space and my dashboard is a space. My solution is to transition to Safari. But I hate the top control section of the browser compared to Chrome.

>so many sites now have "endless scroll"

I hate this misuse of Ajax to create endless pages. It ought to be illegal.

Yep, this is driving me nuts since upgrading to Yosemite.  Seems to happen possibly more often when there are multiple scroll panes within a page in Chrome. 

I've also noticed that if you are on a page that does not need to scroll and you still scroll down, Chrome will automatically start to pull in the back direction.  Maybe as some people have stated above, the browser still thinks the page is too short to scroll while loading, so it's starting a "back" behavior?  Maybe there's a way to disable this on short pages in Chrome (or with BetterTouchTool).

I think Chappsnet is right -- change things to 2-finger back/forward navigation and the problem seems to go away.  Have to get used to that, though.

[Sorry, I should have waited and replied all at once...]  Chappsnet's solution on 2-finger back/forward navigation in Mouse Settings in combination with enabling a single finger swipe action in BetterTouchTool, it all seems to work fine now.  For the single finger swipe left action, I set the action as "Command+LeftArrow". That triggers the browser's back button shortcut.  You can do something similar for the forward button.

I'll throw my complaint on the pile too.

This definitely only started happening post Yosemite-upgrade, but the last couple of Chrome updates seem to have exacerbated the problem.

Well, I don't have Yosemite and we community guys are supposed to try to give answers to questions that we have tested but I have to say, I notice that so many of these posts relate to the usage of Chrome.   And I ask myself could it be that it is the Chrome and Yosemite combination that is causing the problems ... rather than an Apple fault alone.

I'm still using Mavericks, not Yosemite, and it's a problem for me. It started inexplicably about two months ago, never had this problem before.

richardonheights solution didn't quite work for me, but I might have stumbled on a fix while trying it that might help some. My back and forward was already set to two-fingers. But then I set the "Swipe between full-screen apps" action to FOUR fingers instead of three, and it seems to have fixed the accidental triggering of the back/foward actions.

Hope it helps you!

Same issue...just seemed to start a couple weeks ago.  Happening on my MB Air and my iMac at work...both on Yosemite.  Very frustrating. 

Ye im also just gonna toss my complaint in here, Same problem using my MbkPro and iMac.

I thought I was alone with this problem.

I guess I have to turn off swipe gesture and use a browser plugin to do that, like I used to. *****. But what ***** more is Apple breaking things that used to work.

This is only happening for me in Chrome, and it appears to be a Chrome bug which should be fixed soon. It's currently fixed in Chrome 42 beta.
