[MacOS 26 Tahoe M1] Game is nearly unplayable on Tahoe right now
Maybe this was to be expected but yeah, it's the existing problem that existed in the previous version where you lose control of your hero but multiplied by x100.
Match ID: 458391784 Maybe you can't tell much but I could not edge pan to the top of the screen anymore. I could edge pan to the left, bottom and right.
Let me know if any additional details are needed.
Maybe a little unrelated, what are the chances of porting the game using Game Porting Kit? I have played games like Cyberpunk that was ported to Mac natively and those run really well!
Hi,
I'm having same issue, sorted it out temporarily with this settings:
Having the same issue since I upgraded the squoia to Tahoe. I don't know if anyone has the same trigger, but I noticed this top edge panning issue only happens when I alt tab from the game client.
Which means if I launched Dota 2 and at no point alt tab, there wouldn't be any issues, but once you do, whether when its still loading the animation or you're in the middle of a game, live games watch, or replay, the edge pan would suddenly not work, unless you hod down right click, issuing a move command while having the cursor at the edge, or you use the arrow key to pan it upwards.
but same, left, right, bottom is find it's just upwards.
I'm copying my own comment from what is now a closed issue because it's a duplicate of this.
I'm guessing this my not be a dota2 problem but the macOS problem. I too have this problem, but I noticed that the problem only happens when you alt tab from dota2, the moment you launch the game client and at any point once you alt-tab the issue will happen, you can't edge pan upwards and the only way you can move the camera up is by the arrow ket or holding down the right click on your mouse, which means constantly issuing move command.
This is clearly an issue with the new Tahoe macOS, and one of the difference I noticed is that there's a popup when I launched dota2 and it something like a widget panel where it allows you to adjust stuff like songs, screen brightness, sound volume etc. You access this by clicking Command+ Esc , you'll see what I mean.
I first thought that Id always have to relaunch steam, and relaunching dota2 doesn't do the work, but when I decided not to do anything but go straight to demo and test the edge pan, relaunching Dota 2 seems to fix the issue. But it's still too troublesome, and that's when I noticed the issue had to be the widget panel thingy, because the Dota 2 sounds stops for a moment when I access it with the command+esc.
Anyway, I think I found a temporary fix to make it go away without having to constantly relaunch the game client or steam. Just click the command+ esc, you'd see the cursor changing back to the regular one instead of the modified dota2 one, all you have to do is wait for it to pop up and then left click anywhere to close it. You can close it by pressing command+esc again, but I find just left clicking it to close it does the trick, and you'll find you're able to edge pan as usual again. I'm running on M1 and its been years, so maybe its a little slow, but the panel don't appear instantly, if thats the case for you, you really need to wait for it to appear first, you'd notice some lagging when you try to edge pan even when it appears. Sometimes just left clicking once it appears don't work, then what you need to do is try to edge pan when the widget panel popped up, you'd notice sometimes it stops you from edge panning to the right too, but just give it a second or two, it'll start edge panning again.
Once you can edge pan in all direction with the pop up, you can close it and it fixes the issue, unless you Alt-tab or comman+esc again. Yes the widget panel also causes the issue, but you just have to repeat it. I think the important thing is to wait for the panel to load entirely, so even if it already appears, you wait for maybe 2 seconds before closing it. I also tried changing the screen setting to exclusively full screen, this fixed the issue, but it somehow causes other issue, because the cursor gets smaller, and this isn't just how it appears, because it takes a lot more mouse movement to move the cursor from 1 end of the screen to the other. Also I'm not entirely sure what exclusive full screen means but I'm assuming it doesn't allow you to alt tab. Because when I did, it does alt tab, but it doesn't move you to the other tabs, you can hear the Dota sound stops when you alt tab, but your screen is still in Dota, but there aren't edge panning issue.
I don't know if Dota 2 dev can fix this, but I hope macOS fix it with an update, because I have the habit of using alt-tab between games and breaks, and it's just annoying having to fix it, and not being able to alt tab for anything the entire game. Anyway, I hope someone who's more tech savvy can let the people at apple know because I really don't know how to report the bug or explain what it is.
I’m also experiencing this issue on macOS 26.0 (Tahoe).
Steps to reproduce:
- Start Dota 2.
- Alt-tab to another app.
- Alt-tab back into Dota 2.
Problems observed:
- Edge pan scrolling upward stops working (other directions still scroll).
- The cursor changes to the default black macOS arrow instead of the in-game “finger” pointer, so it’s hard to see where the mouse is pointing.
This makes it very difficult to navigate the map or interact with UI elements.
Additional context:
I noticed other users here reported similar problems — loss of edge pan, cursor reverting after alt-tab, and severe control issues on macOS 26, especially on Apple Silicon (M1/M2).
I've figured out how to consistently fix the issue temporarily. Before that I thought you'd have to edge pan top and all direction after you press command+esc,and it may take from 1-2 seconds to maybe 5seconds. I edge pan to the top and it just seems stuck as always but it's fine to the right so I figured what If I edge pan to the top right, and it works every time. I think the left corner works too, but I'm not sure, since it always works to the top right corner I don't really try anything else/
Hi there. Like everyone here, I have experimented with all flavours of solutions, but I think I have a permanent fix I albeit I am still trying to understand exactly what is causing the issue. What I know:
- The issue started occurring after upgrading to macOS Tahoe 26.0.
- I scroll with edge panning in Dota, but only to the left, right, and bottom;
- When running the game in windowed mode, the issue does not occur.
- Initially, I thought this was due to the widgets that were introduced in Tahoe and completely disabled these. This did not resolve the issue.
- I now believe that there is a panel of some sort that is registered when pushing the mouse pointer to the top of the screen. Therefore, macOS takes over the operation, away from Dota, and hence, edge panning does not work.
How to fix this issue currently:
- Test the game in windowed mode to verify this resolves your issue by going to settings -> video -> display -> use advanced settings -> display mode -> select windowed.
- Demo a hero to test if it is working.
- If it works, which it will/should, select Exclusive Fullscreen from the display mode dropdown and enjoy your game.
I believe this is the only viable solution until:
- macOS does an update, or
- Dota 2 does an update, or
- If someone figures out which panel is causing the issue and finds a way to disable it via a setting or an AppleScript.
Let me know if this helped :)
Hello, so I used the "Exclusive FullScreen" method to fix this problem, it runs well for a couple of weeks.
But I just want to report that recently, when there is a group fight there is still the "mouse out of control" situation. Hope you can fix it by the coding update. Thanks!

Since Apple is actively prompting users to update their systems, many more players will likely encounter the same issue. It’s quite annoying to perform these steps every time you launch Dota. I’m not sure how it can be resolved, but I’d really like this issue to be tracked and fixed.

This issue happens to me on Feb. this year, and then Valve fixed it on June or something, so I think they have the clue how to fix it. Now this issue happens again, even using the exclusive full screen mode, it happens on 7min and sometimes just mouse out of control. Please fix it, ruins a lot of games already.
@danginsburg @EricS-Valve @gdrewb-valve @mikela-valve
Yes, it is fixed, tested from my end and runs well, thanks so much!
And please remember this fixing log, hopefully the code helps on the next update! This bug happens in the same way in updates this year.
I apologise @kisak-valve but it seems like this issue returns intermittently. Not as bad as before but sometimes it just happens during a fight where my camera drifts and I can't control my character and I have to spam "Space bar" to centre on my hero.
