I've got an iMac on Ventura 13.5 with a connected Magic Mouse and a Magic Keyboard. I am sharing the Magic Mouse and the keyboard with another Mac (Ventura 13.5). The two devices are a foot apart, they both are connected to the same Wi-Fi, and both are signed in with the same Apple ID. The Mac has a second monitor connected to it via HDMI.

Screenshot of the Display settings arranged in the following order: iMac MacBook, and Dell monitor


With increasing frequency, the iMac has started to randomly disconnects from the MacBook. Then, one will only see the image on the Display settings. This is rather annoying as I use the mouse and the keyboard to work on the MacBook.

Edit : To add more clarity, the issue as far as I understand is that the Mac display gets disconnected. That is, I can only see the iMac under the displays in the attached image. As a consequence of this disconnection, the universal control fails too.

Attempted troubleshooting

  1. Updated both the iMac and the MacBook to Ventura 13.5
  2. Switched off and switched on both the keyboard and the mouse.
  3. I noted previously when I am in a Zoom meeting on the iMac, the MacBook gets disconnected from it. But I do not have Zoom open anymore.
  • When you say “the iMac randomly disconnects” are you referring to Universal Control? Your question refers to a mouse/keyboard but then goes to “Display settings”. It’s tough to follow. Can you edit with some clarification?

  • Thanks @Allan, I might be getting confused with the terminology as I'm fairly new to the Mac setup. I've edited the question now. Commented Aug 15, 2023 at 1:14
