Facetime on new IMAC not working

I bought my iMac two weeks ago and cannot get my FaceTime to log me in either. It works on my old Mac and iPad 2...I had to change the DNS on my iPad 2 to get it to work. But that was before I bought my new iMac.

You would think, Apple would step up and resolve this

Try System Preference -> Network -> Wifi/Ethernet -> Advanced -> DNS->

Then add 8.8.8.8 & 8.8.4.4

Hope this helps!

Thanks. That fixed the problem for me on my 2010 Macbook.

Thanks NeonMiles

The DNS settings fixed the bug for me.

I had also set the Date and Time settings and Time zone to automatic.

3.06 Intel core 2 duo Imac

osx 10.7.5

Same thing happens to me.

I purchased OS X 10.8.2 and am trying to use Facetime on my Intel Based iMac . I have repeatedly done all of the following:

#1 -

Verify your Mac meets the FaceTime system requirements

#2

Verify that you are using a valid Apple ID at appleid.apple.com.

#3

Check that your email address is verified in FaceTime > Preferences. This info. from Apple is wrong. My FaceTime Preferences are grayed out!

I can't believe that Apple has gotten so bad! As my User Name shows, this iMac is my 18th Mac. I began with an Apple IIe. For heaven's sake if anyone knows why FaceTime doesn't work given all I've tried please give me a clue as to what I need to do.

Thank you NeonMiles -- your fix of

Try System Preference -> Network -> Wifi/Ethernet -> Advanced -> DNS->

Then add 8.8.8.8 & 8.8.4.4

worked on solving the problem on my iMac!

Thanks! This worked for me on my MacBook.

Unfortunately, my boyfriend tried the same thing on his MacBook Air and it totally locked him out of his computer.... any thoughts?
