Sonos can't connect to my mac for music library on iTunes

I am no longer getting the error message but Sonos can't seem to locate my music even when I do it manually and find the required folder.

It is the standard Itunes folder.

Other posts say to change the name of your computer in Preferences/Sharing but they don't mention that the name must be less than 15 characters and that you must then reboot.
I ad problems with "\\MyComputer not responding" errors. Traced problem to a difference between the computer name in Preferences\Sharing with the NetBIOSname in Preferences\Network\WINS as explained in [url=https://sonos.custhelp.com/app/answers/detail/a_id/2414/]Manually sharing music on OS X[\url] which pointed to [url=https://sonos.custhelp.com/app/answers/detail/a_id/2413]Mac OS X Music Sharing Help[\url].

Solution:
1.) In Preferences/Sharing, change computer name to something less than 15 characters
2.) Reboot which will change the NetBIOSname to match the Sharing name.
3.) In Sonos, go to menu Manage/Music Library Settings.../
4.) Select Music, then click on the - (minus) sign at the bottom of the dialog box
5.) Click on the + sign and add your Music folder.

Wait while Sonos indexes your iTunes Music Library and then it works like a charm.

Today I encountered the problem of not being able to access my music library with the Sonos system software.
A tip in the FAQ's gave me the answer and it works fine now.
Follow the directions on how to set your Firewall to accept Sonos.
On my MAC I opened System Preferences.
Click the lock and enter password for computer to change settings.
Click Security> Firewall> turn on Firewall if it is not
Click Firewall Options > click +below list
A dropdown will show you the Applications on your computer
Click on Sonos>ADD
Click OK and you should be good to go.(I hope) this is my first time setting up a Sonos product.

Additional step that I also took was to rename my computer from Bruce Smith's iMac to Bsmithimac. Then added my music library onto Sonos after deleting what was currently on it. This might have triggered the sharing to work, also.?

Sharing can run into difficulties with computer names longer than 15 characters, or containing special characters. This doesn't happen all the time, but it can cause trouble. Just a note for others, after you rename your computer you have to restart it before the name change takes affect.

Glad you're all set Bruce.

What country are you based in? Our European lines are open as we speak. Please try again.

Having same issue, have changed to El Capitan operating system, have deleted, upgraded, added, till im blue in the face.
This is the most frustrating thing I have ever faced in the IT world. I cannot believe that some thing which is so basic to the underlying value propostion of the product could be so difficult. I still cannot get it to work.
I do not have enough time in the day to deal with this.
You should not have a beta product for prime time distribution.

I'm not a Mac user so can't be specifically helpful. But it would help if you would explain exactly what issue you are having - Any error messages? Missing menu options? You can connect music folder but it won't play.

You can be certain the currently released software is most assuredly NOT "Beta" and there is not a widespread problem with people not being able to connect to their Mac Itunes libraries - it is to be expected that those who do have issues will post in this forum and those who don't have a problem don't post.
