Loss of connection and focus with MacOS Sequoia

[KenYoshida]

Synergy has been working flawlessly to enable sharing of mouse and keyboard across computers (Linux host, Macos client). But after upgrading to MacOS Sequoia I've been having problems with a loss of focus of the cursor and mouse on the macos side. The mouse cursor will stop responding, and it takes seconds for it to reestablish connection. It will jump from one window to another, losing focus. Turning off synergy eliminates the focus and jumping problem on the macos side. This has made synergy functionally useless for me and am hoping that this is a bug that can be squashed.

I was having issues like that and then it just completely lost connection to the server and wouldn't come back.

I managed to get the connection back and a "fairly stable" connection by doing the following on my mac
System Settings -> Privacy & Security --> Local Network

In there, I revoked access to Synergy and then switched it back on. That seems to have sorted my issues. Hopefully, it will do the same for you.

[KenYoshida]

Thanks. Will give it a try. Initially didn't work, but is working for the moment.

[KenYoshida]

Unfortunately, it works for a little while, but stops working randomly.

I have just recently upgraded to Sequoia and have the same problem.  I tried the above and it didn't resolve the issue. I then fully removed Synergy and re-installed still no fix.

Hopefully a Synergy update is due soon with the fix!

EDIT: The "server" is a Windows 10 machine, and client is MacOS. The above occurs in this configuration. I have changed the Mac to be the server, and windows client, and for now it seems to be stable-ish. Transition between mac and windows is a bit jerky

[KenYoshida]

I'm finding that adding the synergy.app to the firewall (add under network/firewall/options) in macos greatly improves stability.

Same issues here, but between MacOS Sequoia and MacOS Sonoma

[KenYoshida]

Well..hell. Now that I wrote it, the same problems came back...

[spazool]

@KenYoshida Until we have an update to the apps, try swopping the host / client around (if you can). I have noticed better stability now having the mac as the host.

[CVQuesty]

Mine are both Macs.  It matters not

[John Colombo]

Mostly replying to follow, as I'm also experiencing this same issue with my Sequoia client connected to a Win11 server. My Sonoma client, which is connected to the same server, has no problems.

What makes this particularly bad is that simply having Synergy running and enabled causes the mouse to jump offscreen randomly, even when using the connected mouse. Swapping the host is not feasible for my setup, so I must disable Synergy entirely on the Sequoia system.

I've tried both suggestions above, but the problem persists. Is this forum the equivalent of a support ticket, or should one be filed more officially?

[John Colombo]

Followup post: filed a support ticket.

[CVQuesty]

I have been able to get the session working without dropouts for a few hours now by specifying the node's adapter in the "local networking" screen.

[KenYoshida]

I've noticed better stability following update to MacOS 15.0.1.

[KenYoshida]

I've noticed better stability following update to MacOS 15.0.1. But, it still randomly stops and the cursor randomly disappears.

Thanks for letting us know and I'm glad that 15.0.1 helped a bit.

Is the behavior the same whether TLS is on or off?

[CVQuesty]

It's still a problem though, man.  It'll be find for a couple hours then gets all glitchy and gross and unusable, then it just comes back as if nothing ever happened

 

[spazool]

Yup 15.0.1 I think has made it worse. I am still getting glitchy results when the Win 10 PC is the server with the Mac as client. When swopping controls it works a lot better with the Mac as server. 
 

However, I have noticed that on the Mac diagnostics show synergy-service FAIL (localhost ping unreachable etc). I will send this as a separate support ticket. Resetting Synergy on the mac doesn't resolve it. But the system works.

We posted a help article which others in this thread may find helpful:
macOS 15 Sequoia firewall breaks network connection

@spazool Would you mind enabling Synergy under Local network (in macOS, under Privacy and Security), and see if that helps?
 

[spazool]

Hi Daniel, I have synergy-service already enabled under there. Is there another binary that would need to be added?

[Daniel Evenson]

The error posted is related to synergy-service (which is for the auto-discover and syncing settings), there are other binaries (for example synergy-core, synergy-tray), but they are for different functions. 

Do you have a firewall application/manager other than macOS, I'm wondering if this app might be blocking the localhost connection - would you mind checking?

[spazool]

No, I am limited to macos fw. There is no other fw on the system. Unless something completely unlikely like Sentinel Pro might block. Hmm. I will investigate and let you know. I don't have any errors or warnings from other apps to this effect.

 Check if there’s a newer Synergy version or beta release that includes a fix for macOS Sequoia compatibility.

I am on 14.7 and have been having this issue for as long as I have been using Synergy 3 on my Windows/Mac setup.
