Fix: Mac OSx - !!!!!! Critical !! Unable to bind to media udp port no #####.

[Gilmofo]

Hello Everyone,

I worked all day yesterday and this morning to find a fix for that error on my OSx Sierra... and I find it!!! :-)

This is the message I got: 

Unable to open port ###### on any network interface! You will not be able to join sessions
!!!!!! Critical !! Unable to bind to media udp port no #####. Try restarting the JK client.

Even if my firewall was properly configured, and UPnP activated... I was not able to connect. So, I started to presume there is something to do with the Security of my Mac. 

After read some article, I found the GateKeeper of OSx sometimes put some apps downloaded from the internet into quarantine and do not allow them to be executed properly.

So, I search for a fix... and I found that.

-----------------

1) Close and Quit JamKazam client if it's open

2) Open a Terminal, type and press Enter:

Code:

xattr /Applications/Jamkazam.app

If you see see something like this appear ...

Code:

com.apple.quarantine

...thats mean JamKazam as been Quarantined by the GateKeeper. 

3) To remove JamKazam from the quarantine, in the Terminal, type this command and press Enter...

Code:

sudo xattr -r -d com.apple.quarantine /Applications/JamKazam.app

The Terminal gonna ask for your password, type it (you not gonna see anything appear during you're typing) and press Enter.

After Enter, the command should be accepted by OSx and JamKazam should be removed of the quarantine. 

4) To check, type again...

Code:

xattr /Applications/JamKazam.app

If nothing appear, that's mean JamKazam is not in Quarantine anymore.

5) Restart JamKazam Client... it should work. (crossed finger)

It works great for me... hope it's gonna help some of you. 

Best Regards,

Michel

100% fixed mine. Couldn't connect with another player on my network, ran this command, worked right away. Thanks!
