Apple has just confirmed that MacOS Monterey, set to release later this year, will support Adaptive Sync on external displays. It wasn’t mentioned during the keynote at the Worldwide Developers Conference this week, but it was during a WWDC developer session. MacOS Monterey is the latest version of the MacOS, and it will soon be available on MacBooks, iMacs, and Mac Minis. Adaptive Sync will allow a lot of these newer Macs to support variable screen refresh rates, possibly making them more viable for gamers.
