Apple’s latest macOS update makes the 2018 MacBook Air’s display brighter. Released on March 25th, macOS Mojave 10.14.4 increases the brightness of the Air’s display by 100 nits, resulting in 400 nits of brightness. The company confirmed the change in its release notes that the new software “corrects the default screen brightness for MacBook Air (Fall 2018).” The change was first discovered by Reddit users. Apple’s own website now lists the Air at 400 nits instead of 300 nits.
If you want to enjoy a brighter display on your MacBook Air, you’ll need to visit the Settings app and check for updates. There, you should find macOS 10.14.4 ready to be installed so long as you haven’t already installed it. Afterward, let the software install. Be sure to connect to a reliable Wi-Fi connection and ensure you have sufficient battery power.
