MiddleClick doesn't work because it starts before Magic Mouse

[jordiramu]

Hello,

First I'd like to thank you for the great app!

I use MiddleClick on a M1 iMac (24", 2021) with MacOS updated to Monterey.

Whenever I restart and then login, MiddleClick seems to start too fast; it is set as a startup item. It looks like MiddleClick starts just before the default (included in the package) Magic Mouse is initialized and as a result it doesn't work. So.. the middle click functionality implemented by MiddleClick.app is not present unless I quit MiddleClick application and start it again, manually; but this makes it unusable as a start item.

As a workaround I used Automator to create a new app which runs a very simple Bash command (actually two): sleep 5 && open -a MiddleClick and had this Automator generated app set as a startup item instead.

Is there any way to make MiddleClick activate/load/set its functionality after the mouse is initialized?

Thank you

I have the same problem after wake up.

After conecting an Apple Trackpad I also needed to restart MiddleClick to make it work with the trackpad.

When the trackpad disconnects by itself (because of course it does, it's wireless for some reason and wireless is a synonym for unreliable) and then reconnects, I also have to restart MiddleClick to make it work again, which is annoying.

You should try out the new pre-release. I haven't tested it with wireless devices, but it's a much more stable build. Please continue here if the issue persists.

This issue does persist in the pre-release :( If you need any help debugging, please ask.

I'm having a similar problem with versions 2.5, 2.5.0.1 and the prerelease 2.6 (can't test any other versions since I'm on an M1 machine - running macOS 12.6 Monterey):

When disconnecting / reconnecting a Magic Mouse (eg. just turn the Magic Mouse off and on again - no sleep/wake cycle), MiddleClick no longer registers middle clicks and the app needs to be restarted.

If I understand correctly, the relevant code is this, which appears to call the multitouchDeviceAddedCallback function - for some reason this is not firing:

https://github.com/artginzburg/MiddleClick-BigSur/blob/a9fd092c5dc93944062a533167c12c42daad5986/MiddleClick/Controller.m#L92-L95

I can see this because on the command line, the Restarting app functionality... does not show up when I turn the Magic Mouse off and on:

$ /Applications/MiddleClick.app/Contents/MacOS/MiddleClick
2022-10-09 14:37:27.258 MiddleClick[63555:8582952] Starting all listeners...

*** Recognized (0x6b) family*** (26 cols X 18 rows)
*** Recognized (0x70) family*** (10 cols X 15 rows)
...nothing else shows up here...

If it would be better that I open a new issue for the problem of reconnecting, happy to do so!

Workaround

To quickly restart MiddleClick, use macOS Shortcuts: create a shortcut that quits MiddleClick and opens it again:

Then right click on the shortcut and select "Add to Dock", for easy access:

@artginzburg I guess you haven't been able to reproduce the problem I described above?

Do you have an idea why it could be happening?

[karlhorky]

Ok, I think I found the issue. Seems that the commit 5aca15 broke this (the removal of the call to CFRelease(item) for the M1 build).

I've opened a PR for this, to instead call IOObjectRelease(item): https://github.com/artginzburg/MiddleClick-BigSur/pull/54

[jordiramu]

Thank you, @karlhorky ! I have tested your patch and it works for me. Hopefully it will be included with the next release...

[karlhorky]

Great, looks like my patch is included in 2.6.1 (already available in Homebrew), thanks @artginzburg for the release and Homebrew bump!
