Can I connect my magic mouse to my Vision Pro?

Looking at the Keynote, and after seeing that Vision Pro can mirror your Mac, using a mouse would be huge! If you want to work on InDesign, for example, hand gestures are not gonna be able to cut it. I hope the mouse is something that will be integrated in the Mac mirroring mode!

Unfortunately, Apple Magic Mouse is not listed as an accessory with Apple Vision Pro. Don't ask why, because Magic Trackpad can be used. Though this is so, there is a sentence in the Apple Developer Design Guidelines for pointing device input (under the visionOS section): "When people use an attached pointing device that supports gestures, like a trackpad or mouse, the pointer hides while people are gesturing, minimizing visual distraction."

I don't know whether this is a mistake or not. You can ask an Apple customer specialist about wheter Magic Mouse is compatible or not on the Buy Apple Vision Pro page.

Actually, it's too early to tell what Apple accessories will be compatible with the newly announced Apple Vision Pro VR headset. No one here works directly for Apple as we are just fellow Apple-product users and only know what Apple provided us at the WWDC presentation today.

Looking at the ad that was provided for that device, I'm not sure why you would even need a mouse as it looks like you pretty much interact with it via hand motions.

Good point! I can see the usefulness for that better now. Thanks!

I suggest that you (& the OP) submit your comments directly to Apple here: Product Feedback - Apple
