"Enable Streaming" option won't stay selected when restarting Steam client on MacOS

[sfsdfd]

I'm streaming from a Windows 10 machine to a Mac. I've seen the following bug occur occasionally on MacOS, but it's suddenly worse than ever.

ISSUE:
The "Enable Streaming" option in the "In-Home Streaming" pane won't stay selected when restarting the Steam client.

OS:
MacOS X (El Capitan)

STEPS

(1) Check the "Enable Streaming" option in Steam.

(2) Reboot MacOS and load Steam. Observe that the option is checked, and the full library of other machines on the same network is available for streaming.

(3) Quit Steam on MacOS. Restart Steam without rebooting.

(4) Notice that the library is no longer available, the MacOS client cannot see the Windows machine, and the "Enable Streaming" option is not checked.

(5) Check the "Enable Streaming" option. Notice that the option appears to be checked, but the library is still not available and the machines still cannot see each other.

(6) Quit the Steam client (without rebooting) and restart the client again. Notice that the "Enable Streaming" option is no longer checked. Notice that there is no way to get the machines to see each other again.

(7) Reboot the MacOS machine and start Steam. Notice that the option is once again checked, and the macines can once again see and stream to each other. (But return to step 3 to see the problem recur.)

I'm having the same problem. I'm using mac os 10.11.6 (15G31) . Though I'm trying to stream from my mac to a Steam Link in another room. I'm using the steam Beta update build package version 1471977975.
My mac was crashing when I started streaming with the non-beta build, but I am now having the above problem with the beta build. So I can't start streaming as the steam link does not detect the computer.

Same issue here.

I posted this issue in both the Mac and (General) In-Home Streaming forums as well -- however your step-by-step write up is much more informative.

Exact same issue here, including the "one time only" working post reboot.

This is also from Win10 to Mac El Capitan. Definitely started with the most recent Mac client release, I was streaming successfully all weekend before the update, and post update ran into the issue.

Tried contact support directly but was sent here.

Yeah I also asked Steam support about this and was sent here. Mine's Windows 8 to OSX 10.9.5.

Enable Streaming won't stay ticked and won't find the PC on the network once ticked. Upon restarting the Steam client it will be unticked. Restarting the Macbook will fix it but only until the Steam client is closed again.

Two moths later - the bug still exists. I keep hoping that Steam client updates will finally fix it, but no luck yet.

Two additional features that I've noticed:

(1) When I first reboot and start Steam, MacOS gives me a "do you want to permit incoming connetions" dialog. If I click Yes within 30 seconds or so, the client discovers the Steam streaming server a moment later, and dispalys the full library. If I wait more than 30 seconds or so, then even if I click Yes, the machines fail to discover each other.

(2) After closing and re-opening Steam (at which point the machines won't discover each other again until I reboot the Mac client), that dialog doesn't pop up.

(3) The dialog strongly suggests a MacOS firewall issue. However, the firewall simply isn't involved. Turning off the MacOS firewall completely does not resolve the problem, even after restarting the Steam client on the Mac. The only thing that resolves it is rebooting (which, as described above, only resolves it once).

I've tried investigating this problem further - e.g., recording the Event Log entries over the time range during which the Steam client starts, and comparing asuccessful-connect-startup vs. can't-see-the-other-machine-startup. No difference as best I can tell.

I am having this same problem too. Using 10.11.6, and Windows 7 Pro. Have tried both the regular and beta release of the Steam clinets, adding firewall rules, turning off firewall on both machines, hard wire/wireless network connections, and big picture mode. The Windows machine will show my mac computer in the list but it says "not connected". I have not been able to resolve the issue, and it is really frustrating. In Home Streaming used to work just fine. This really needs to be addressed and fixed by Steam!

FYI: I also had this problem in MacOS El Capitan but am seeing this as resolved after upgrading to MacOS Sierra. It's seems strongly possible it's a OS issue (or related to an OS issue) resolved in Sierra.

Having same issue, seemed only on my main machine with windows 10 but is now an issue on the win 7 laptop as well.

[i;m gonna c*u**9*m]

Having the same issue.

Windows 7 desktop
MacBook Pro (2015) 10.11.6

Downloading Sierra now to see if that fixes it
