RIME Rquirrel 0.16.1 broken DVORAK in MacOS.
I saw 0.16.2 release in sometime few days ago:

one of my friend told me too that's somthing you need to update on Rime config but mostly okay, I think it should be fine so I continue upgrade and reboot and my DVORAK keyboard layout just dead.
There's some discuss on github issue but it won't works e.g. they mention one command:
defaults write im.rime.inputmethod.Squirrel BasicKeyboardLayout -string "com.apple.keylayout.Dvorak"
It WON"T help.
you need upgrade ~/Libary/Rime/build/squirrel.yaml keyboard_layout from default to dvorak
.

once it updated you can re-deploy your Squirrel.

Your Squirrel will act with dvorak normally.
Thanks god it only take my ~ 1 hour to check this issue and if you are dvorak keyboard layout with squirrel user you should see this.
Thank you and hopefully you have nice day!
