Mountain Lion AirPlay Mirroring (iMac to AppleTV) Not Working

Nope. Not buying this limitation Apple. OK, so I get that you think we all need GPU hardware H.264 encoding to make this go, but as many have already said, Air Parrot is doing it. So, at least for desktop machines (see below), there is absolutely no valid reason to not have this ML feature enabled on a broader scope of "older" platforms. I'm running a mid-2009 iMac with a quad-core i7 clocking at 2.8 GHz. Be glad to let one of those cores that is sitting mostly idle take the load for mirroring.

(Why not non-H.264 GPU enabled MacBooks? Should be users choice, but the load on those machines is going to make them warm up pretty good and put a pretty good draw on the battery. But again, should be users choice.)

Solved my own question for anyone who run into the same prob. I assumed that I already had the latest mountain lion OS since I bought my iMac couple of days ago (Mac OS X Lion 10.7.4). I was wrong... Got my redeem code for a free upgrade (Mac OS X 10.8) and now works great.

Gdluck

I agree, there should be an update to ML (a free one please) that allows older Macs to airplay under the user´s choice, letting the costumer know that it will perform better or worse depending on the model we own if thats the issue. If a third party app can make the job then Apple is totally capable of coming up with a more integrated solution.

I was about to ask if you were running ML. Good for you! Congratulations!!

Hey fitzpatty

I read somewhere in this same discussion that somebody got a refund and still kept Mountain Lion. You should give it a try there is nothing there to be lost more than what already is. Good luck!

Yes. There was no downgrade enforced so far on my Mac.

Same with me, it ***** I can't use air play from my imac, little dissapointed!!!

If you do request a refund on mountain lion and get it, you are allowed to keep the OS installed. But be warned, you will get no updates for the software.

Which is a security risk. Louis, do you happen to know how to do a downgrade back to Lion? Not sure whether freshly installing Lion and restoring my data from Time Machine would work because Mountain Lion did some Backups already to my Time Machine disk.

Im very upset too, I just bought ML because of this functionality, and If I can use airplay on itunes, and in my Ipad 2, I dont understand why not on my 2009 macbook pro, I just bougth also RAM 4MB memory more, so I dont thnik I should buy a new mac when this one is good enough so Im going to try with air parrot,

Misled again... previously Australian 4G not compatible with new iPad and now this... Airplay not compataible with my 2009 MacBook Pro after investing and upgrading to ML, very sneaky... can I get refund on ML?

As suspected ML has a fair few issues that are slowly being shaken out. Battery issues, drag and drop, sleep issues and overheating problems. These combined, with the Airplay fiasco, means that Apple should be looking to issue an update fairly soon. I've advised several users not to upgrade yet, as ML isn't delivering all it's promise yet. As with all upgrades it pays not be first. Mind you, the lack of Airplay on such a huge swathe of Apple laptops and desktops with this upgrade, when there is a workaround, has used up a lot of good faith and trust. This action implies that just under the skin, there is a MS gremlin lurking.

Hi yes another very annoyed customer after having wasted time and money on mountain lion with the main attraction being airplay mirroring which won't work on my i5 2.4GHz Macbook pro. I will look at the legal remedies since it seems a case of misleading advertising.

This realy ***** I want a refund on Mountain Lion - Airplay Mirror was the only featyre I wanted

Mid 2010 Mac is not old - hope this is not a sign of things to come

I can't believe how many posts ther are about this subject. If Apple doesn't react to this huge number of unsatisfied customers, it could be the beginning of the end for Apple. I don't really care about the $20 for ML. It has some pretty nice features and my early 2009 Mac Pro runs a bit faster. What really gets me though is the fact that the most important new feature that obviously thousands of people were looking forward to is not backward compatible. The most important reason why I was converted to Mac was that I thought these computers wouldn't grow old. At least, not after only 2 or 3 years or that we would be able to easily expand. My Mac Pro is still an extremely powerful machine but for some unexplained reason, the Mirroring feature doesn't work. Apple cannot ignore this. We are loyal Apple customers, we've all spent a lot of money and we believe Apple should offer us a solution. Apple always says "it just works". Well this one doesn't. Please fix it. I still believe in Apple but I am very disappointed. What good is Apple TV without mirroring. Cheers.
