checkerboard displayed when playing back video

Having the exact same problem using native OS X screen sharing to control a Mac Mini. Just posting so Apple might be convinced to address the bug in the next update.

I also have this problem and it has broken my home theater setup. I have a Mac Mini connected to my TV and I use my MacBook as my "remote control". Now I have to disconnect my MacBook to play content that I have legitimately purchased through iTunes. Hopefully Apple will fix this soon, but I doubt they will. I'm thinking of getting a small form factor PC and running Linux on it to get around this problem.

To the posters above:, I've opened bug id# 12222529 with Apple through the developer website.

The work around is to turn off screen sharing on your remote computer. In my case I am using an iMac to control a keyboard less and mouse less Mini hooked to my HDTV. Fortunately I had a wireless keyboard and USB mouse laying around so I am able to use the Mini but I have to use the HDTv as my screen.

Another work around is to simply launch the movie with your remote control computer and then turn off screen sharing imediately. In theory (I have not tried this), the checkerboard should go away and hopefully you've only missed a minute or two of your movie.

I think everyone agrees this is unacceptable as screen sharing worked so well on Lion and now does not.

Note: I also linked this forum discussion to the bug report.

Thank you for doing that, wbraat!

Another user here with a ruined system.

Mac mini plugged in to TV. Controlled by Macbook Pro. Irritated that I cannot watch movies that I have paid for through iTunes. Inexcusable.

I went and purchased a device called iPazzport, basically a hand held bluetooth touchpad and keyboard to control the Mini, until this gets sorted out. Not ideal but it does work and is not terribly expensive.

+1 that this needs to be fixed. There are several ways to protect the DRM content from being streamed onto other devices. This is the worst of the possible solutions, and is only pushing people to find alternatives to the normal Apple ecosystem.

Another vote to fix this. Wish I hadn't upgraded the Mac mini to ML.

- and another vote..

MacBook-screensharing control of MacMini connected to TV is a very common thing !!!

I spent unreasonable much time analyzing this before i found this Forum; thank you, all.

I too am unhappy with this. I purchased ML and an ATV for the airplay feature and it does not work the we I was led to believe it would. I could understand the DRM issues but when I've paid for all of these DVDs and iTunes movies they shouldn't be blocked IMO.

Please correct.

Yep - I ran into this one too - screensharing my HDMI-connected Mac Mini onto my MacBook Air caused the checkerboard effect on DVD Player and iTunes videos.

The thing that saved me was Mobile Mouse Pro - it uses a proprietary wifi-based protocol to control mouse and keyboard input from your iPad, iPod or iPhone. Jolly useful!

And, of course, the free Apple Remote app on your favourite iDevice works a treat with iTunes on your Mac Mini if Home Sharing is enabled.

VLC Player solves the issue. You have to change the audio to be sent to AirPlay besides the normal AirPlay icon but it plays mounted disks, DVDs, and vid files just fine. Hopefully Apple fixes the issue but it is at least a workaround.

This is MacBookPro to AppleTV by the way

And another. I had a choice in HTPCs, and I chose the Mini. As I also have an all Mac household, and as the Apple Store rep said there'd be "no problems," I bought the Mini and a Pegasus Tbolt array, loaded all of my media up and proceeded to FAIL. Come on Apple! I really don't want to use VLC for this (I use it for other things, but dammit, all my stuff is loaded into iTunes, and iTunes is Apple's product, so why under ANY circumstances would it break on Apple hardware with content PAID FOR and licensed via Apple?). I don't want to have to mess around with external controllers, nor should I have to. Did Apple fire all of the QC personnel? Come on, Apple. You are so much better than this.

+1. Dissapointed Apple user. My Mac Mini controlled by my MBP my wife's MBA or our iphones suddenly became less appealing.
