Show macOS app switcher across all monitors

universal-switcher

defaults write com.apple.Dock appswitcher-all-displays -bool true
killall Dock

I have rectangle installed for window management so that could be interfering with it?

Have no clue, frankly (did not use rectangle before), but I would try disabling 3rd parties one by one, until you see that it's working. I can imagine that it won't help, but it's worth checking. You could also try logging in into your user holding Shift or do something like that to exclude 3rd parties, just to quickly check if they're the problem.

I have one external monitor connected via a USB-C to DVI cable through a dock. The weird thing is, I've used this same config on a 16 in Macbook pro 2019 and it worked then

I see, I believe this just another hint that it might be software related, and not related to the hardware.

Sorry for taking so long to reply here. I actually have the app switcher showing on both monitors now, after a reboot. I previously set the config twice (for good measure 🤷) with no effect:

$ defaults write com.apple.Dock appswitcher-all-displays -bool true
$ killall Dock

However running defaults read com.apple.Dock appswitcher-all-displays did not show me anything. Then, I ran defaults write com.apple.Dock appswitcher-all-displays -bool true; killall Dock; again, rebooted and then defaults read com.apple.Dock appswitcher-all-displays showed me 1 and the app switcher worked for me.

I have no idea why or how but I'm happy it's working...

@jonathanbell 👍

It started working for me after a few reboots! 🤷‍♂️ Thanks for the help @jonathanbell @grigorye 🎉

Glad it started working for you. So strange!

Thank you!

I wish this was default behaviour!

nice thanks👍

Didn't work for me: Macos 12.1 (21C52) macbook pro m1 2020 13'

Worked for me after a restart.

MacBook Pro (16-inch, 2021) M1 Pro - Monterey 12.1

The following worked on the first try:
defaults write com.apple.Dock appswitcher-all-displays -bool true
killall Dock

Amazing!

Also worked for me on 12.4 Monterey, 16" M1 Macbook Pro

Didn't work for me on 12.4 Monterey, 14" M1 Macbook Pro, even after reboot

Initially, this was not working for me either (12.4 Monterey MacBook Pro 13-inch, M1, 2020). I guess the reason was that I had some other dock settings changes which were conflicting with this. What worked for me was resetting the dock to its default state and then running the above commands again.

To reset the dock to its default state:

defaults delete com.apple.dock; killall Dock

And then:

defaults write com.apple.Dock appswitcher-all-displays -bool true
killall Dock

This worked for me.

I could not get this working on an M1 MacBook pro 12.4 Monterey, even with a restart. @sanp's fix worked for me. Thank you!

Works for me on M1 Macbook Air 12.3 Monterey. No fix was needed.

Alas, not working for me on a M1 Max MacBook Pro running Ventura 13.0.1 - anyone else managed to get this working on Ventura?

defaults write com.apple.dock appswitcher-all-displays -bool true && killall Dock – works for me on Monterey

Make sure that dock in com.apple.dock is LOWERCASE – it didn't work for me with uppercase – probably because my file system is case sensitive.

dock written in lowercase worked for me. Thank you so much

Works for me when dock written in lower case... thanks all 🙌

Doesn't work on Ventura

defaults write com.apple.dock appswitcher-all-displays -bool true && killall Dock works for me on Ventura. No reboot needed.

OMG, this is awesome, thank you!

Lowercase dock from this message finally worked for me on Ventura (Following 1+ years).

This worked for me - no reboot required
Sonoma 14.1.1, M2 Max 14"

thanks so much for everyone involved in the solution, very much appreciated

Maybe the dock in com.apple.dock should be lowercase

defaults write com.apple.dock appswitcher-all-displays -bool true
killall Dock

+1 lowercase com.apple.dock version working without reboot
macOS Sonoma 14.16.1, M3 Pro

✔️ works here Sequoia 15.1
