How are yours set up ? with mini display adapter to HDMI cable to TV ?
Hi jcl1688.

Yes, I'm running 10.8.2 (12C60) - latest one available. When I bought my MBP in mid 2009 I also bought an adapter (one that fits those apple ports) + HDMI cable at the same iMac store (weren't even cheap), and frankly they worked fine for 3 years. I don't seem to find that icon that I could find previously, was it moved to somewhere else in the config menu perhaps? Am I overlooking something (else)?

nielsdutch,
hook up the hdmi cable to TV and on your mbp > system preference > hardware > display >
check box with show mirroring options in the menu bar when available.
the mirror monitor box will show on the menu bar (top of you screen), click on that icon should get you going.

There's only two round boxes to check (above) and 2 square ones (middle and bottom) that don't mention anything about mirroring. The previous software did!

I am not sure what you mean by 2 round and 2 square boxes, it should be an icon on top screen, just like bluetooth icon, volume icon etc when hook up with tv and mbp; when tv and mbp both turned on, click the mirror icon on your mbp, the image of mbp should be in sync with tv.

niels - that omni-present bar at the top of your screen is the Menu Bar.

I cannot be held responsible for the things that come out of my mouth.
In the Windows world, most everything folks don't understand is called a virus.

Right, sorry i get what you mean now. I checked that box at preferences etc (I did already before) but there's no icon different than the ones I had showing in my menu bar. Now what? The TV keeps telling me 'no signal'.

WAIT I just changed to another hdmi port and the symbol did show up, but my tv is still telling me 'no signal' with a full black screen!

'no signal' should be good sign, click on the 'display' icon, see how it works else
shut down tv and mbp, reboot mbp and turn on tv see you can get the image on the tv screen.

Well this is getting strange, the menu bad icon dissappeared as I pulled the adapter from by MBP and I haven't managed to get it back eversince (just before, the tv even did show my MBP's screen!). But whatever I'm doing now, i don't manage to get the icons back!

I'm suspecting more and more this is a real strange flaw of the software, the icon won't return even after having tried t reconnect everything is all possible orders (also just like i did when it did show up). Any wiz-kid that has experience with this or am i simply screwed?

Recently I just bought a MacBook Air with Mountain Lion preinstalled. Previously I was using a MacBook Pro (it was now STOLEN! ) and always connect the MBP to my TV set. When I plug-in the Mini-Display to HDMI cable (same cable I use with my MBP) to the TV, black screen appeared. After I change the screen resolution ( System Preferences > Displays) from Best to fit screen to scaled (try for each of the resolution), then the video & sound appears on the screen.
QUOTE Thanks
