The RuneScape Launcher is currently an Intel-based application on Mac, supported through Rosetta 2 compatibility.

As of Mac OS 26.4, you’ll see a warning notification for the Jagex Launcher highlighting support is ending for these kinds of applications. Compatibility is due to end with the release of Mac OS 28 in 2027.

We know this will seem a little disconcerting, so we’re sharing this quick update today on what to expect. We will be developing a Mac native version of the Jagex Launcher, which will launch before the rollout of Mac OS 28.

We’re fully committed to ensuring there’s no disruption for any of our Mac players because of the changes to compatibility. We’ll let you know the launch date for the Mac native version of the Jagex Launcher later this year!
