That did it Now everything works well as far as I can tell.

alexkirsz · January 22, 2026, 11:33am

Ah, nevermind, now both button 3 and button 4 get double presses

Andreas_Hegenberg · January 22, 2026, 11:38am

ah very strange, but could you post the logs once more? I think we are very close

alexkirsz · January 22, 2026, 11:56am

The behavior is weird. After my computer woke from sleep, I was seeing single presses, with sometimes the press being missed. But now it’s back to double presses. Here are logs with only pressing button 3.

Some more changes in 6.100 - it will probably again require to toggle the mouse off / on.

alexkirsz · January 22, 2026, 3:46pm

I’ve updated, so far so good!

ageorgios · January 23, 2026, 11:35am

I am not sure Scroll Acceleration is working as expected.

Whichever value I put on Vertical strength, the change is scrolling is in speed and not in acceleration.

Even when I put 0 in strength Formula: output = input × (1 + strength × √(|input|/4))

I should have gotten the same effect as not having acceleration right? But I am still getting just higher scrolling speed

Andreas_Hegenberg · January 23, 2026, 10:57pm

@ageorgios it might not be possible to combine this with smooth scrolling, I'll check next week!

I have started to create presets for every Logitech mouse I own (which are quite a few by now). I have started with the MX Vertical. The presets are supposed to showcase various parts of BTT functionality, I will soon collect them on Logitech Mouse Support · BetterTouchTool Documentation

Requires BTT 6.106
MX_Vertical_Preset.bttpreset (11.1 KB)

MX Vertical Features in this Preset:

* The big thumb button can switch spaces when dragging it left/right, show mission control when dragged up and show your desktop when dragged down

* The big thumb button shows the BTT window switcher when pressed briefly

* Page back/forward buttons goes back/forward when pressed quickly

* Page forward button scrolls left / right while being held & dragged left/right

* Page back button shows spotlight when held longer

* Clicking the scroll wheel keeps the standard middle click behavior

seldo · January 26, 2026, 9:56am

thanks for the preset! I didn't know I could do so much with so little buttons...
so how do you like the MX Vertical?

telmofcosta · January 26, 2026, 11:29am

My MX Master 3 is no longer recognized

I was able to properly map all buttons, but now after I rebooted my mac, BTT does not find it when I click scan. It is detected correctly on the Generic Device Configuration.

Andreas_Hegenberg · January 26, 2026, 12:29pm

do you have it configured additionally in generic devices or was this just for testing? Generic devices will in general have priority, thus the logitech support will not work properly when a generic device config for the device is added (especially if the exclusive access checkbox is enabled like in your screenshot)

Andreas_Hegenberg · January 26, 2026, 12:58pm

@seldo it's not for me, I find especially the button on the top not very comfortable to reach. I much prefer the MX Masters

telmofcosta · January 26, 2026, 2:46pm

do you have it configured additionally in generic devices or was this just for testing?

I added it just for testing.

I was using 6.106. Updated to 6.108 but still with no luck. Anything I can do to diagnose what could be wrong?

Andreas_Hegenberg · January 26, 2026, 2:46pm

You can try capturing the logs:

It could be a permission issue

//edit: after having it in generic devices you might need to clear BTT's trash, I think there might be an issue where generic devices keep their connection active even if put to trash.

telmofcosta · January 26, 2026, 3:06pm

After removed from generic devices and trash cleaned:

The system is blocking access to it (0xE00002E2 = kIOReturnNotPermitted). Possibly the mouse is in a weird state or the permissions are somehow broken.

I'd try:

Restart BTT
Turn off and on the mouse to clear any weird state
3.) Check System Settings => Security & Privacy => Input Monitoring. BTT must NOT be listed there. If it shows up there, remove it.

Worst case you can reset all permissions for BTT by doing this:
1.) Quit BTT
2.) Run this terminal command: sudo tccutil reset All com.hegenberg.BetterTouchTool

telmofcosta · January 26, 2026, 4:10pm

Had already done all of that with no luck

However,

The problem exists when connected to Bluetooth. When I connect the mouse using the Logitech receiver, everything works as expected. This is not a solution for me, though, because I use the receiver on my desktop. On my MacBook, I use Bluetooth.

EDIT: Oh, I rebooted my Mac, and now it works well . Everything is green on the logs now. Really sorry for the trouble and time spent. There was a time MacOS was BSD…

Anyway, thank you.

seldo · January 27, 2026, 9:50am

back at my desk since last week, on 6.100, BTT is not recognized the top button of the MX Vertical (I think I was on 6.100 last week).

I updated to 6.106 (which required a restart of BTT) and the top button is still not working with BTT

@seldo looking at the log I believe this is the same issue that was already fixed yesterday with 6.109! (check for alpha version updates)
