Universal Control has been broken too long

There are endless threads here and on reddit about Universal Control just disconnecting randomly and none of the updates over the last 2 years has fixed it.


The common answer given when folks exhaust all of the troubleshooting guides is that it's bluetooth interference. Maybe so, but other KVM solutions I've used never had this issue moving between my Mac Studio and MacBook Pro (both Apple Silicon). If bluetooth did get spotty, Apple should build it robust enough to try to reconnect immediately and it does not. You know how I know? Try this next time your cursor disappears from the other machine. On the host, keep "System Settings" open and click on "Displays" ....it will instantly reconnect. You will only see one machine but as soon as you click the remote machine will reappear instantly. This is an issue on Apple's end, the simple fact that I can force it into a behavior where it instantly reconnects means Apple did not build this solution robust enough. I was even exploring running a cron job to kill UC everyone couple of minutes just to keep it refreshed. PLEASE FIX THIS APPLE!!!!

I use it all day, both machines. MacBook is up on a riser so it would be tough to type on and use the track pad. It's really hit or miss if you just do a cursory search on the net you will see this is impacting some unknown percentage of folks. Is it 100%... I doubt it? It is maybe 5% of edge cases? Probably more accurate. Should the root cause be investigated and fixed? yes, please and thank you.

Hence the reason I asked. It will take lots of feedback to get them to even look at it. If I had a ballpark figure to have it running I might be able to reproduce. You mentioned Bluetooth congestion. I only have keyboard and trackpad, but could connect a speaker. Does it take more than that?

Most likely. The funny this is I don't really have a lot of bluetooth stuff running. I do however have dozens of smart home devices running on 2.4ghz wifi and 2.4ghz Zigbee. Yesterday I split my network up so only the Mac Studio and MacBook Pro were on their own 5ghz SSID (still the same network, just a different AP name and forced to use 5ghz without switching). So far, the connection has stayed (but I did see some really laggy mouse movements). I'll report back if this fixed it, but this isn't a true fix as Apple needs to build a fail-safe for bad connections (reconnect, etc). Otherwise it just lets the mouse cursor and connection disappear without trying to reconnect. I'll report back if this worked.
