Media keys on Mac

[JohanLeirnes]

The KC_MNXT and KC_MPRV does not work on Mac, The MPLY works thou, have i missed that this is intended and there is another code for mac media keys?

[tmk]

hm, I don't have Mac nor idea on this.

I think you may be able to know what keycodes you can use on mac by skiming the sources around here.
https://opensource.apple.com/source/IOHIDFamily/IOHIDFamily-606.1.7/IOHIDFamily

[tmk]

Hm, looks to me like those keys should work.

kHIDUsage_Csmr_ScanNextTrack and kHIDUsage_Csmr_ScanPreviousTrack handled in IOHIDConsumer::dispatchConsumerEvent are KC_MNXT and KC_MPRV in TMK.

When running usb overdrive it recognizes the next track button on my keyboard as a different next track button then on the internal keyboard, wonder if there is 2 almost identical codes for next track. Do you know of any program that can see what scancodes that im sending with the internal keyboard for mac?

[tmk]

I don't know how to get scancode on OS X. But from reading source codes I guess USB Apple Keyboard sends F6 or F8 as normal keycode and Fn in Apple vendor specific usage page.

What do you mean with "internal keyboard" actually? Macbook builtin keyboard?
And I don't know much about how Mac media keys work. Fn+F6=previous track and Fn+F8=next track, right?

[JohanLeirnes]

Yeah the internal keyboard on my laptop :) f7 and f9 is prev and next. i could be like that. You can choose to use fn+f7 or just f7 for prev track via config in systemprefs

[JohanLeirnes]

But the config in systemprefs only works on the built in keyboard not on my tmk one even thou it has a fn layer

[tmk]

Fn key on tmk is completely different from Mac. It doesn't send any key code basically. Mac mediakey functions on macbook and apple keyboard are vendor specific unfortunately, systempref works only for apple hardware.

But as I said previously Mac seems to support standard HID media control codes too. Tmk can send only the standard codes.

To me weird thing here is why MPLY only works.

Any other Mac user here? can you confirm this problem?

[JohanLeirnes]

The mnxt and mprv do work with itunes i just noticed, but not with spotify or vlc.

If i look in USB overdrive the MPLY and VOLU and VOLD only have one entry (one scancode i guess) but the MNXT and MPRV has 2 entrys each.

[tmk]

Interesting.
I'll look into OSX sources again later. It may handle apple media key and standard one as different key events.

[JohanLeirnes]

If you want any help just tell me, im not that good with programming but I can troubleshoot for you if you want to :D

[kairyu]

Do you have tried this #160 ?

[JohanLeirnes]

I have not will try it

[tmk]

Thanks, kairyu.
Oops, this issue is exactly same as that. It was not so long ago, I blame my short memory :D

The "Play/Pause"(KC_MPLY) works good on Apple OS. But "Next/Prev Track" buttons are unfunctional.
Apple OS use "Fast Forwad"(F9 on Apple keyboard) & "Rewind"(F7 on Apple keyboard) instead.

bhaap, close this issue if it works for you.

The MFFD and MRWD does not work for me. Not in itunes nor in spotify. USB Overdrive does not even recognize the command (does not register a keystroke when i press the button). Maby I have a old master. need to check that. brb
