Since the most recent Vision Pro update, I can't connect my MacBook to the Vision Pro

I hope this is not a silly reply. Are you trying to connect only by looking at the MacBook? Or are you also trying to go through the Control Center? I found that if I try to connect by looking at my MacBook Air, the "Connect" display only sporadically appeared. Turns out that if you're not in a well-lit area, it won't appear. But Control Center always works for me.

Is your MacBook also running the latest software?

Review the settings are all in place: See your Mac screen on Apple Vision Pro - Apple Support You might also try signing out of your Apple ID on the Mac - Restart it again - then sign back in. Make sure keychain is enabled after you’ve done this.

I had the same problem. Support call could not resolve and they were doing more research.

I ended up finding that if by going to the MacBook or Mac mini and selecting the control panel from the menu bar and then mirror the Mac screen, I got an option to mirror to the Vision Pro.

After doing that it works fine from the Mac or VP.

Just got my Vision Pro when 1.1 came out so I can't speak to how it worked before but (almost) every time I connect I have to manually go to the virtual display settings

It does put the little floating 「 Connect 」 button on top of my MacBook Pro just often enough to let me know that that is a thing that could happen though so that's great

Mine is also quite sporadic too, I definitely agree with you about being in a well lit area, seems better then, however my Mac is black and my rooms are usually not well lit, so it's a case of opening the blinds all the way up...ufff

I started having a similar problem with 1.0.2. The Connect sign would only appear sporadically. I was able to connect without resetting, but it took a lot of patience.
