Q: No Signal on HDMI TV After Lion Upgrade

Well, yet another video foopah with Lion.  Lion seems

to have severely borked playback of iTunes purchased

HD movies ONCE AGAIN.  Tried to watch Iron Man last

night, and every few minutes the video would just stop

for a couple seconds, then continue.  Audio was unaffected.

This renders my iTunes HD movies totally unwatchable!!!!!!

The same thing happened with the 10.6.3 to 10.6.4 update.

Only, it would only happen 2 or 4 times scattered throughout

the movie.  It didn't get fixed until10.6.6!!!!!!!!!!!!!!!!

Apple can't even update an OS anymore without destoying

usability of its own material.  Shame on you Apple!!!!

As I stated in a previous post, all my other video material

plays just fine!!!  Maybe it is time to just plain abandon

iTunes as a source for video as Apple cannot deliver its

material reliably!!!!!

Updated my late 2010 MBP 15" and also my new mini (the last version to have an optical drive) and both had HDMI issues.  They worked but not correctly as with Snow Leopard. Also my NAS would not be recognised as a volume. I then "upgraded" back to the last known OPsys that worked 10.6.8 and all is well yet again.

WIth Lion too many unresolved issues.

I managed to have signal with the option+command+p+r trick but now I have other major problems:

Very slow response of graphics

No video or sound playback

No ntfs support from tuxera.

Are they going to fix this or what?

Can I ask for a refund for buying lion?

Bye Lion. Welcome Snow Leopard again.

Since I'm using my Mini to run a production PBX it's extremely important that it's stable.  I woke up this morning to find all phones down.  My phones in my house, and the 10 phones at the remote site that connect to my Mini.  What happened?   Well, once a week I have the Mini set to reboot on Sunday morning at 3 am.  Last week - no problem.  This week - it would not restart!   The top of the mini is normally warm.  This morning it was hot.  I turned on the TV to find a black screen.  I held the power button for 10 secs to shut it down.  It came up to a black screen again.  I left it for 15 minutes like that.  The computer would not start up and it was hot hot hot.   It's like it's spinning it's wheels in some CPU intensive loop.  I did the pRAM thing and it came back up.  Whether this is an issue with the HDMI or something in addition is wrong I don't know.  Regardless, it's time to bail out.  It's too stressful worrying that my Mac is not going to start.  People could be trying to call 911.  A woman in the remote location is pregnant and due August 22, but could go any day and would need the phone.  So this is a serious issue for me.  I've decided to go back to Snow Leopard. 

The strange this is I'm having no issues with Lion on my Mac Pro.  As for switching the mini back to SL - it's now 12:55 pm and it is finally installing.  You can't just install it on top of the Lion OS.  On certain sites, people said to create another partition and it will install.  Not for me.  After hours of fiddling with this I got it to work by installing Windows XP part way.  The Windows install allowed me to delete the partitions and format them as NTFS.  Then I used the SL install disk to run Disk Utility and reformat the drive as MAC OS JOURNALED.  Now it's finally installing. 

I'm really disappointed in Lion.  I've never had reason to distrust Apple until now.  This OS was not tested properly (if at all) on the Mini.  Steve Jobs said Lion would be released in July.  It seems it was released come he'll or high waters.  I don't think I'll be upgrading Lion to the Mini again.  Even if a fix comes along, I won't trust it. 

Goodbye Lion, and thanks for wasting several hours of my time and causing a lot of stress. 

Buy this device to solve the handshaking connection issues when switching inputs or turning on Av receiver after mac startup ..... Gefen HDMI Detective!!

Thank me later!

I think the issue is worse than HDMI handshaking.  I cannot access it through Screen Sharing either when it starts going squirly.  The CPU runs hot, the computer will not even boot up.  At 3 am, the TV is not on.  So there would be no handshaking taking place.  Last weekend it rebooted 100% OK.  This weekend it failed.  Then even after turning the TV on it would not work.  It appears to be an issue with the Operating System that goes beyond the HDMI handshaking, but I could be wrong.

Anyhow I'm back to Snow Leopard and after spending almost a full day reinstalling everything and restoring things from backup, I'm happy again.  I've also learned a valuable lesson.

I agree with you Kevin, Lion borks Mini's old AND new

and is something that goes beyond HDMI handshaking.

While I was running Snow Leopard, I could turn on any

piece of gear in any sequence and my system would work

flawlessly.  I could also just turn on the Mini by itself,

and access it from another Mac using Screen Sharing!

Has Apple become so big that OS people don't talk to the

hardware people or their software people before making

changes?  I have been seeing a lot of different threads

in all the forums that are starting to point to this.

I'm not sure what the scoop is on why this happened.  We all discovered this flaw within moments of installing Lion, so it's not like it was some far fetched bug that you'd only find during very odd circumstances.  This issue is clearly happening frequently and even a small amount of testing would have found this. 

My theory is the deadline.  We know that Steve Jobs said the new Lion would be released in July.  We also know that he micro-manages staff and can focus on pretty things at times.  Don't get me wrong, I have tons of respect for this man.  I just think he pushed to have it out in July because he said it would be ready by then.  The developers likely knew darn well that it wasn't ready for the Mini.  It's more of an issue with what the boss says goes!   That's my humble opinion.  :)

Haha, that's "petty" things - not "pretty", although Macs are pretty. 

I had experience working in that kind of environment Kevin.

The powers that be would proclaim the edict that things will

be in production on such and such a date, even though we

said there were serious issues "they" said it must ship anyway.

So we spent the next months dealing with disgruntled customers

and being accused of being "incompetent".

This, sad to say, has become the paradigm of modern business.

Get it out the door, generate profits, then fix it later.

You are happy right about that.  It seems businesses all over are doing the following:

- Cutting back on staff.

- Cutting corners to save money.

- Taking shortcuts hoping nobody will notice.

The end result of all of this?

- Poor reputation due to poor product.

- Poor economy due to people being downsized.

- Weakened respect.

I don't know if Apple is cutting staff, but I know many companies and governments even are cutting back on employees in an effort to save money.  Meanwhile the workload is the same.  You can't expect one person to do the job of 4, and that could very well be the issue we are seeing with so many products today - Lion included.  If you want it ready by July, then you need to ensure you're not scrambling right up until the due date.  There has to be time to properly code, test, and debug and test again and again.

Anyhow, I think it will all be ironed out.  Patches will be sent out that will hopefully fix it up, but still, it's a blow to Apple and very disappointing.

Ideally of course they would have tested it widely on a variety of equipment. But how many of their core test team, or even the beta group, use OSX on a HDTV? I expect the vast majority of testing would have been on laptops, imac or standard PC monitors (or lovely cinema displays).

You and I know that minis are popular as HTPCs, but clearly that passed someone by. I'm starting to fall out of love with it frankly - the 'it just works' is falling to pieces, and Plex (my client of choice) might have a great media manager, but the playback part still can't change the screen res/refresh rate to match the content after nearly 3 years of saying 'its coming soon'

It would be interesting to come across someone or people who are having issues with PC display monitors too.  I don't really think it's an HDMI issue.  There's something else rattling around in there it seems.

Don't lose too much hope - Apple just had to get it out in July and I'm sure they are fully aware of the bugs in it.  I've been reading where people are booting up and getting a gray screen with the Apple logo, and a spinning gear icon that just goes and goes and goes.  So there are other Lion issues out there besides this one.  I hope that they will soon have all of the issues fixed and an update released.  That way at least they'll save some face.

This is something that I find very disturbing:

From this thread:

http://discussions.apple.com/thread/3248110?tstart=0

This is the quote:

"Additional Background: I have had a couple of calls with Mac support and they have been unable to tell me whether this is a "design feature" or a flaw in the Lion OS because they have had no similar reports and they do not have the latest hardare available running Lion Server to test to see if this happens with other monitors. (They also, of course, don't have the VX2835wm monitor.)"

Apple does not have the latest hardware with the latest OS!!!!!!!

I don't know if this poster was just misunderstanding, but if he wasn't

this is very disturbing.

The thread wasn't directly related to our issues, but just seeing such a

comment is disturbing.
