Not working with MagicMouse, Macbook Pro, Big Sur about linearmouse

[lujjjh]

The issues mentioned above have been resolved in v0.5.1.

Thank you all! Feel free to reopen this issue if the problem still exists :)

[lujjjh]

Thank you for reporting this. Would you like to paste the relevant logs so that I can dig this further?

1. Open Console.app
2. Select View → Include Debug Messages
3. Select your MacBook Pro and click Start streaming
4. Search CursorManager and choose Category

You may see some logs (about every 5 seconds) describing which devices' acceleration and sensitivity are updated and which devices' are skipped. I'm guessing that Magic Mouse is skipped.

I'm having the same problem and when modifying the accel and sens via LinearMouse I see nothing in the console.

I am also not seeing anything in the console when I follow those steps.

[lujjjh]

Oops...I forgot to point out that View → Include Debug Messages should be selected in Console.app.

[rachid-block]

For the record I found that option under "Action" -> "Include Debug Messages"

Here is the message:

Magic Mouse 2 is skipped as it might be a trackpad

Thank you for your reply. I attempted to fix this in #36. I don't have a Magic Mouse, though, so I can't test it. Please let me know if this fix works.

Edit: Fixed some mistakes and updated the build URL.

[acefer]

I tried the new build with the fix and the console app show these messages.

Magic Mouse appears to be quite different from a regular mouse. Perhaps this is the reason why SteerMouse and USB Overdrive do not support Magic Mouse (and Magic Trackpad). I'm going to mark this issue help wanted because it's probably not easy to fix.

However, I'm still curious about the structure of Magic Mouse in I/O registry. It might be useful to run

ioreg -n "AppleMultitouchDevice" # or maybe it's not an AppleMultitouchDevice

in the terminal and share the relevant sections of Magic Mouse. So that I can see whether there are any other properties that can affect acceleration and sensitivity.

"Apple Internal Keyboard / Trackpad," for example, is as follows (please mask properties like SerialNumber / LocationID):

Hey, i cant get linearmouse to work with my magic mouse 2, none of the settings seem to make a difference. Has there been any developments on this?

Hey, i cant get linearmouse to work with my magic mouse 2, none of the settings seem to make a difference. Has there been any developments on this?

No, I'm afraid. Pull requests are welcome if someone who uses Magic Mouse 2 discovers a solution to modify the cursor acceleration.

From the I/O registry data posted by acefer, the HIDPointerResolution property exists, so it's not difficult to modify the cursor sensitivity.

However, the property HIDPointerAccelerationType is missing, which represents the key of acceleration data.

I can think of two approaches to consider:

1. Manually set the HIDPointerAccelerationType property value to "HIDMouseAcceleration" and configure acceleration by the HIDMouseAcceleration property like other mice.
2. I've noticed the HIDPointerAccelerationTable property which could be useful.

Another question to me is that the default sensitivity of Magic Mouse 2 seems to be different from other mice, according to the value of the HIDPointerResolution property.

[lujjjh]

I've rework the mouse detection algorithm in #82. I would appreciate if you can verify if this version works for Magic Mouse.

NOTE: The default sensitivity of Magic Mouse is 404, so LinearMouse's default sensitivity (1600) might be too large for it. If Magic Mouse moves too fast to control, please quit LinearMouse with Trackpad and re-connect the Magic Mouse (turn off the power and turn on again I guess).

Thank you very much!

[caolan-ferry]

Seems to be working now for me! Thank you for this fix :)

[lujjjh]

@caolan-ferry

Seems to be working now for me! Thank you for this fix :)

Thank you so much for your testing! Are sensitivity and acceleration working as well?

If so, could you please tell me if the default sensitivity (1600) is too fast to control for Magic Mouse? I shall decide whether to release this version or to block Magic Mouse for the moment until per-device configuration is implemented in the future.

[caolan-ferry]

@lujjjh
I have the sensitivity set as shown in the screenshot attached, is the default you are mentioning when the checkbox is ticked?

[caolan-ferry]

Also it seems that some of the magic mouse gestures are not working correctly when using linear mouse, such as swiping back and forth between browser windows

[lujjjh]

@lujjjh I have the sensitivity set as shown in the screenshot attached, is the default you are mentioning when the checkbox is ticked?

At the first launch, LinearMouse would set the acceleration to 0.6875 and the sensitivity to 1600. I hope it's not too fast for the Magic Mouse.

Also it seems that some of the magic mouse gestures are not working correctly when using linear mouse, such as swiping back and forth between browser windows

Is this a new issue or does it also exist in previous versions? If this is a new issue, could you perhaps confirm which functionality or functionalities are causing it by turning them off?

Thank you!

[caolan-ferry]

@lujjjh seems its specifically the reverse scrolling setting stopping this gesture from working. I also noticed that when linear mouse is running, sometimes my trackpad becomes extremely slow until i 'refresh' its sensitivity in system preferences.

I also think the default sensitivity is good!

[lujjjh]

seems its specifically the reverse scrolling setting stopping this gesture from working.

Thank you for providing this information. I'll try fixing it.

I also noticed that when linear mouse is running, sometimes my trackpad becomes extremely slow until i 'refresh' its sensitivity in system preferences.

Oops, this is a bug! When trackpad is reconnected (after Mac waking up from sleep), its acceleration and sensitivity are unexpectedly updated. I'll fix it soon.

I also think the default sensitivity is good!

That's great! So this issue can be closed when the two problems above are solved.

[lujjjh]

Have you tried swiping in the other direction while reverse scrolling is enabled? I'm not sure why it stops swiping gestures from working.

[lujjjh]

I can reproduce it with trackpad. I've also noticed that reverse scrolling for Magic Mouse and Trackpad does not work well in Safari, which is an issue of Scroll Reverser as well.

I'm going to re-implement reverse scrolling functionality and I believe it could fix both swiping issues and the ‘Safari’ issue.
