Hi,

This thread is not going to help you with an iPhone 6 and it's version of Messages.

The whole thread is about Messages on a Mac (Computer).

Hi,

Good to hear.

Here are the instructions for what finally worked for me (OS X 10.11.6 Macbook Air late 2011):

Removing Configuration Files:

• Turn off Wi-Fi from the menu bar.
• Navigate to /Library/Preferences/SystemConfiguration/ in Finder by pressing ⌘ + Shift + G.
• Select the following files
  • com.apple.airport.preferences.plist
  • com.apple.network.identification.plist
  • com.apple.wifi.message-tracer.plist
  • NetworkInterfaces.plist
  • preferences.plist
• Copy these files in a safe location so that if anything gets messed up, you can easily restore them.
• Delete the files.
• Reboot your Mac and enable Wi-Fi again.

These instructions were from here: http://www.iphonehacks.com/2014/11/wi-fi-problems-mac-os-x-yosemite.html ( I only found 4 /5 but it worked nonetheless).

Same here.....

i think that is Apple servers fault, maybe they have problems with efficiency, to many computers wants to activate iMessage and FaceTime

I've downgraded (clean install) OSX to 10.11.3 and problem still occur, so this is no software issue

Even though this concern was posted a while ago, I figured I would chime in in hopes of saving some people the runaround. Especially if they are travelers. I had this problem too, and fixed it by making sure the date and time were correct. Sounds simple, though its odd that the two should be related. For some other technical reason, my date and time did not update automatically as it normally does when I returned from abroad. In the time and date setting, enable the manual option and click on the correct time zone on the map, then recheck the automatic option. This will hopefully solve the issue for many of you. Cheers

polarbreeze1,

Thank you so much!

I've had this problem for over a year (MBP 13" Late 2012 running 10.11.6) and have gone through so-so many calls to Apple support . Have tried everything from deleting "Library/Application Support/iCloud/Accounts" and all keychains, system updates (but within El Capitain - as I could not upgrade to Sierra due to being locked out of the App Store... and also compatibility issues with some apps I run for my work), multiple SMC & PRAM resets, genius bar visits, loads of library file deletes, uninstalled a lot of apps, paid for new IO board & all sorts of diagnostics in multiple chat and phone sessions with Apple support staff.

One level one service person even insisted that I reseat my RAM, which is not possible with my MBP, they even sent me a how-to after I pointed out that the RAM was soldered in.

Anyway, your solution worked first time - so thank you again.

Meanwhile, it's slightly annoying that Apple Support knew of this issue but failed to make that info available to their wider team for their troubleshooting.

If I could buy you a beer I would. Thanks again!

yup having the same issue here!

if you have two step security turned on then go to MyAppleid.com and create an App password for messaging.

Generating app-specific password doesn't help.

• Generating app-specific password doesn't help;
• Turning off 2-step verification and trying again doesn't help, as well;
• Turning on 2-step verification - doesn't help;
• Signing out from iCloud in System Preferences - doesn't help;
• Signing on back - doesn't help;
• Signing on to appleid.apple.com with/w-o 2 step verification - is okay.

• Clean reinstall doesn't help;
• Turning off Firewall - doesn't help;
• Handoff between Mac and iCloud devices - doesn't work as well.

Yes, i have same problem.

Hi All,

Another thread suggests that a Contact with Apple Support suggests there may be an issue with these two apps in the OS X 10.11.4 update.
