Full Range XDR Brightness

This is a new approach for unlocking the 1600nits of brightness in Apple's XDR displays, developed in collaboration with @waydabber from BetterDisplay.

It has the following key differences from the previous XDR Brightness method:

• It doesn't clip colors in HDR content - no more washed out colors
• The system adaptive brightness keeps working and uses the full range
• There's no lag when going from SDR to XDR brightness
• Can be kept on all the time without any downsides
• Can work in tandem with f.lux

Downsides:

• It only works on MacBook Pro XDR screens
• The screen will flash one or two times when toggling Full Range

The system will still adapt the maximum nits of brightness based on the ambient light, so you might get a max of 800 nits in a dark room and 1600 nits in sunlight.

Disabling the system adaptive brightness will turn off this behaviour.

Preset unlocking

The Change Screen Preset Shortcut now allows you to unlock various functions that are locked by macOS when using reference presets:

• Brightness Control
• Adaptive Brightness
• Night Shift
• True Tone

Improvements

• Allow overlay dimming to work on Airplay screens when the MacBook is in Blackout
• Automatically use the mirroring method for Blackout when the MacBook is connected to an wireless display

Fixes

• Disable Dark Mode after disabling Night Mode
• Ensure Night Mode does disable after unchecking it
• Fix app hanging when initializing Location Services in some cases
• Fix Dark Mode being disabled erroneously
• Make sure to re-enable keyboard backlight after disabling Blackout
• Fix CLI not working after a few standby cycles
• Fix rounded corners not being applied on app launch
