After 10.6.8 Mini Displayport to HDMI PROBLEM

I will report this again as I have reported it the day after the release of 10.6.8 but after this latest update today I fear Apple is not hearing us. Furthermore while Shades is okay, IMO, that's all it is, "OKAY". I see why it's called "Shades", it's like putting sunglasses on. You lose precious picture quality with a tinted look. I'm beginning to see that it's not wise to do software updates.

Yeah, shades is a way to avoid burning your eyeballs out of your skulls at night, not a solution at all. I've reported it too again after installing lion.

I hate to be the Debbie Downer but at this point I don't think it will be fixed and it looks like Lion will get neglected too. I wish I knew how to code I would develop a plug-in to make the brightness control work. Hopefully someone with that type of know-how does. I'm usually the "Apple fanboy" and hardly ever speak negatively but I'm really upset with them right now over this.

I can confirm this is still a major problem. I purchased my iMac mainly to use the fantastic screen with my Windows 7 machine. Having an actual mac for software testing was just a side benefit. The result of this bug is that I can no longer use my iMac for the main reason that I purchased it, since the keyboard brightness control was the one function I used every day! Apple has turned my $1,999 purchase into a worthless product!

It does feel that way, doesn't it.... 😟

All I can suggest is to keep calling them/bugging them/filling in those reports about the issue.

OK, people. We have the 10.6.8 update, and we can see the files in the update. There HAS to be a file there that changed what happens on Target Display mode with the key commands. Does anyone here have any clue which file/files these are? I'm going out of my mind trying to fix this while I go blind from having my brightness locked at max! 😟

This is insane, the iMac is brighter than the sun and there's absolutely NO WAY to change it. Frankly its unusable. Shocking. Maybe we're ALL just not looking at it right?

I wish I could chuckle at your comment saying, "Maybe we're ALL just not looking at it right?" but I'm so frustrated with Apple right now about this that I just feel like my 27" iMac is rendered useless for future use in terms of installing Lion. I feel like I'm going to be stuck on 10.6.7 until I sell this machine and just buy a plain flat screen and a Mac mini. This is really terrible. How could this be in both 10.6.8 AND Lion??? What's going on?

Hate to sound like a broken record because I am in total agreement with you all (that this is a horrible bug, and disappointed that Apple has not addressed it).

HOWEVER...

1) Apple has not responded to this thread, and likely has not even read it. If you seriously want to have your opinion heard and have the issue fixed, SUBMIT OFFICIAL FEEDBACK HERE. This ensures that an Apple employee will read your message and track the issue. Your grumbling on this forum will do little to help solve the problem.

2) If your screen is ["literally blinding you"], install Shades which is A FREE AND EFFECTIVE TEMPORARY SOLUTION, albeit not perfect. I know we're all frustrated, but this will solve the problem without cursing the Apple gods.

After an Softwareupdate a view days ago, my brightness control works again!

Every time after switching to the PC the brightness is very high but now i can reduce it (with F1).

I use snow leopard and wait until the problem is fixed in lion too.

Not that I am in disbelief of you but I seriously wanna believe it will work for me. I'm just scared to upgrade from 10.6.7 to 10.6.8 only to find out that I'm screwed again. It's a lot of trouble having to restore back. Either Apple has to officially supply an update which specifically addresses this brightness issue or I'll have to see a few others with that same great experience you got. It's just too scary to try this. Doesn't anyone at Apple use their iMac as an external display?? Lordy, I'm surprised this has gone on this long.

I spoke to an Apple support guy about this issue yesterday. He walked me through using a reboot while hitting Command-Option-p-r. Made no difference unfortunately. However I did send him a link to this thread via email.

I upgraded to Lion as a desperate attempt to resolve the issue but that made no difference either.

What I have noticed is that you can set the brightness OK in native iMac mode, then when you swap to external display mode it bascally resets the brightness to max and F1 and F2 have no effect, then if you go back to native iMac, it remains at max.... so I have to wind it down again.

I know this is not the support guys fault so I'm not mad at him, but he did basically say that if the hardware I'm using isn't entirely Apple (ie my Lenovo laptop and Monoprice Displayport-to-miniDisplayPort cable) they are unlikely to take my support case very seriously. Really?? The fact that it USED to work just fine with that hardware, but 10.6.8 brought me tan-while-you-type brightness levels isn't proof enough?

Also, after I mentioned this forum post, it doesn't sound like Apple take it very seriously. Don't expect Apple support to be scanning the discussion forum... I don't think they are.

And if they are.... APPLE!! Please treat this VERY REAL problem with TOP priority and fix the f$%king thing! If you can't be bothered, send me the **** code and I'll fix it.

Has anyone analyzed the files that were changed from 10.6.7 to 10.6.8, yet? I still say this our best shot at fixing this issue until Apple comes around...., -if they come around...

An update... I got a call from Apple support saying that Apple development are fully aware of this issue and are working on it... so keep an eye out for updates... may not be in the immediate future though.

A fix can't come soon enough for me.

I like your ideas, but unfortunately some inputs (eg. digital TV boxes and game consoles) cannot lower the brightness like Shades does. This issue has caused a great 27" monitor to lose a lot of its value.
