A:

Back To My Mac and some VPN clients will fail on OS X 10.9 Maverick if the "Broadband Tuner" was previously installed. This failure happens because the Broadband Tuner sets some system parameters that are too low for Maverick.

 

 

To fix this problem, please uninstall the Broadband Tuner using the installer that can be downloaded at http://support.apple.com/kb/DL420

 

 

Note that you may have to override your security settings to open the installer because it was created a long time ago before developer ID registration began:

- In the Finder, locate the BroadbandTuner.dmg and open it to show its content

- Press the Control key, then click the BroadbandTuner.mpkg icon.

- Choose Open from the shortcut menu.

- Click Open and proceed with the installation

 

 

You need to restart the system to apply the changes.

 

 

A final note: the “Broadband Tuner" is uninstalled when either:

- The file /etc/sysctl.conf does not exists at all

- The file /etc/sysctl.conf exists but does not contain the following lines:

#

# Tuning network for broadband

#

# START

kern.ipc.maxsockbuf=512000

net.inet.tcp.sendspace=131072

net.inet.tcp.recvspace=358400

# END

    Hey all - I have been pulling my hair out for a while on this.  Like many I went though the broadband tuner hoops, multiple attempts of removing and recreating keys under user accounts and lately i've been watching the console and watching errors as I selected and de-selected back to my mac.

     

    What I tried this afternoon is referenced in this support article:  VPN not working after upgrading to Mavericks

     

    I used those terminal lines to set maxsockbuf to 1000000 and my iMac share magically appeared on my remote macbook.  First time i'd seen it in months - it did appear for a short time after installing and then uninstalling broadband tuner.

     

    I think this VPN issue makes sense - that's one of the things broadband tuner supposedly does.  So far so good, i'm keeping my fingers crossed.

    i have not had any luck in fixing the BTMM issue.

     

    I toggled O n the BACK TO MY MAC in System Preference and in the system log i noticed this issue:

     

    Oct 12 14:31:30 iMacHD.local mDNSResponder[35]: register_service_instance: domain 109722711.members.btmm.icloud.com. already registered for HP Officejet Pro 8000 A809 @ iMacHD._ipps._tcp.

     

    is it possible that the HP printer is the cause of the failure to connect to BTMM?

    my other two computers have no problems.

    I doubt it.

     

    Did you recently upgrade to Yosemite? If so read Re: Re: Screen Sharing to Device with iCloud

    Interestingly, I have found native IPv6 to be a problem in Mavericks & Yosemite. I run a full dual-stack with Comcast connection. BTMM seems to prefer IPv6 if it sees you have a routable IPv6 address, but then it fails if your TC is configured to firewall incoming IPv6.

     

    If I set the Mac Mini at home to only link-local IPv6, then it seems to NAT-PMP to setup BTMM. However, even then I have to reboot the Mac mini every once in a while as it starts failing to show up at work. Logs look like a "racoon" error, something to do with an IPSEC VPN tunnel I am guessing.

    Had this problem a couple years ago, got it solved with the Broadband Tuner uninstall. Just upgraded to macOS Sierra and guess what - same problem again. BTMM gives the error "iCloud server not responding." Since I no longer have Broadband Tuner on my Mac, I'm hoping someone can find the conflicting software again this time.

    BTMM is so buggy. I find it works one day, not the next, one hour and not the next. Sometimes a roboot helps, but I have no idea why it works or doesnt. It is a shame because I really count on it, need it. I'm in no rush to go to Sierra, in fact only one of my 3 computers is even on El Capitan for reasons that everything works and I'm afraid to mess with it. good luck but I suspect at some point BTMM will work again.
