Screen sharing broken in Sonoma

The 14.1 update resolved this issue.

Try RustDesk. I play the Sharing Remote Management Remote Login Toggle game about 10 times a day. Here is my hourly scenario. 1. Mac Screen Sharing(easy file sharing), 2. Sharing Screen FREEZES., 3 RustDesk and toggle both Remote Management & Remote Login buttons. 4 Go back To Screen Share rinse and repeat. Very FRUSTRATING. fyi, does not belong in this post but the caps lock icon is horrid. I support 50 users, its 49-1 against it. I just wonder what Apple is thinking.

I'm also running 14.4.1 (on both machines) and a long problem still consists: After starting screen sharing, sometimes the connection will not be established. Login screen tries to connect for ever. If I abort by pressing ESC and trying again, the connection will be established immediately. Very annoying. There is something wrong in error handling. This happens every now and again. Sometimes 1st trial is successful but sometimes not... This whole sh.. is now error prone since the first days of Sonoma.

It became that bad for me when trying to screen share with a friend, we have had to abandon Safari, go over to Chrome and use Google Remote desktop which is free and works flawlessly.

I am experiencing the same issue and after numerous reboots I came to the conclusion to only use Standard sharing type.

(Server Mac mini M1, Client MBP 16 M2, both Sonoma 14.3)

We (our MSP) are "trying" to use Screen Connect as we always have through LiveDesktop in Addigy, but after Sonoma, the Screen Sharing app either gives us the colored beachball or straight up disconnects us every few seconds or so.

In short, it has literally made Screen Sharing unusable in our business, it's that bad. We are now using ConnectWise screenconnect as a workaround.

Currently running Sonoma 14.1.1 using Screen Connect 4.1. It's been behaving like this since day one of Sonoma, and it is still not fixed.

Not great...

Has anyone else updated to Sonoma 14.2? I just updated both my computers today and I've been able to use High Performance screen sharing between the two for several hours (before, it would 1) not work at all or 2) work for just a couple of minutes before the input would stop working from the remote computer to the target computer; I tried using both standard and high performance connections).

I hope this will stick, and that Crapple have finally gotten the thumb out and actually address severe issues like this, which prevents their users from using basic services that have been a part of their platform for aeons.

Please note that the Sharing settings looked very iffy on the target computer (the only "shared" items were the two public folders for the two users on that machine. I removed those and added the entire drive, allowing the default (administrators only) to access the shared folder(s). I also disable the firewall since you are not able to use screen sharing and an encrypted drive. Don't forget to reboot after changing settings like this, just to be safe.

And I have been using Screen Sharing without an issue for every point release of Sonoma thru 14.4.1 with several other Macs running different versions of macOS. Some connected via Ethernet, and most via Wi-Fi 5/6. Same network segment. I have dragged and dropped the /System/Library/CoreServices/Applications/Screen Sharing app to my Dock and locked it there on the receiving Mac.

Senders:

2011 Mac mini - High Sierra 10.13.6

2013 iMac - Mojave 10.14.6

2020 iMac - Monterey 12.7.4 including accessible Parallels Guests: El Capitan, Mojave, Big Sur, Ubuntu 20.04.4, and Win 11 Pro (23H2)

2021 MBP M1 Pro - Ventura 13.6.6

Receiver(s)

M2 mini Pro (32GB) with 32-in 4K UltraFine display

2020 27-in iMac 3.8 Core i7 (40GB)

Here are the recipient (e.g. M2 mini Pro) Firewall optional settings:

and the settings on the Sending 2020 iMac (loki.local) - but similar on other senders:

System Preferences

Sharing : ☑︎ Screen Sharing and Allow access for: ⦿ Only These users: Administrators.

Secuirty & Privacy : Firewall Options:

When you Shutdown the screen shared Mac and you get the spinning cursor, reach up into the Screen Sharing panel and select Close. Then Quit.

Are you connecting on an internal network or across an external network

Screen sharing also stopped working after the Sonoma update. Still works on my old laptop running MacOS Monterey 12.6.3 I get the same pop-up instantly although the recipient says they got my invite. By the time they click on "Allow" I get the message that the connection has failed. Very inconvenient as I use this option frequently. Hope Apple takes notice and sends out a fix. My current computer with Sonoma is a MacBook Pro running Sonoma 14.0. Will test it again with a recipient and ask them to use "Invite to Share My Screen."

Sonoma 14.1 Update seems to have fixed the connection Authentication issue but the Latency issue still remains.

Audio:

Severe echo when trying to speak to the person using the remote Mac

Controlling Remote Mac

Severe Lag when trying to control other people's Mac.

Open Finder for example, then try to move the window and it can take up to 4 minutes before I see it move.

** I tried the same on Zoom and both issues mentioned above work 100%, with No Lag, No echo

Apple has acknowledged the problem. I have opened a case. There is no fix or workaround in Sonoma. An update is imminent hopefully.

I’m using VNC Viewer on my ipad and iPhone to connect to my iMac with vnc server. It’s working for me. I did update all client & server sw when I updated Sonoma.

@ku4hx

Are you using this on an internal connection or connecting from an external IP address?

I'm having the same issue. Tried calling apple support but they were unable to fix it as well. They think it's a software problem in MacOS Sonoma and hope it will be fixed in future updates.
