I have late 2015 issue macbook Pro with
2880x1800 native resolution. How do I use that resolution? The max that I can configure using the built-in tools is
I am on High Sierra.
Apple's System Preferences don't allow you to change to full native resolution.
You can use the displaymode command line tool to change to the native resolution.
Download the binary from the "releases" section, and extract it if necessary. Then from Terminal.app,
cd to the directory the
displaymode file is in and run:
./displaymode t 2880 1800
