However, you might notice what’s not present: any mention of Mac support. Much like YouTube in Safari, Apple’s resistance to VP9 over patent issues (it prefers royalty-free formats like AV1) makes official 4K support unlikely. Take heart, though. As 9to5Google observed, the unofficial Stadia+ extension for Chrome can force 4K on Macs if you’re determined to play in full quality on your iMac.
There are still some limits regardless of what platform you use to play. HDR and 5.1-channel audio are still “coming soon,” so you’ll have to be content with a relatively flat audiovisual experience for a little while. And don’t forget, titles like Doom Eternal won’t play in native 4K. While you’ll get the best Stadia experience possible, the performance won’t outshine a local copy of a game on a well-equipped PC.
