Lion freezes after HDMI switch on Mac Mini

having two newest Models of Mac Minis, both having LCD HDMI Displays connected to them.
both running newest Software of Lion.
there is a HDMI Switch, to switch the 2nd Display on thunderbold which is a Projector between the two Minis.
One of the Minis freezes, when the HDMI port is switched away from it, the other doesnt.
Once i unplug the HDMI cable or switch back to the Port where this "problematic" Mini is connected, the freeze is unlocked and everything works again.
This is only on "the problematic" Mini, the other works fine, even when the HDMI Port is switched away from the second (working) one it does not freeze, nor having any issues.
this is weird, how can it be, that the problem only exists on one Mini with the Same configuration, and not on the other one?
And How can i possibly solve it...

I have Mac Mini (mid 2010) hooked on to 5.1 ch speakers (Bose) and LED TV (Samsung) through AV amp (Bose LS-35), all connections using HDMI cable. The dream system autput is limited to 3.1 (no sound from LR and RR).
When I then configure my speakers through the Midi-setup utility. I can specifically trigger each speaker successfully (control sound comes with the configure speakers tool). The video is also good. The problem is that whatever movie I play and whatever software I use (DVD player or Quicktime or VLC), I hear only stereo. I also tried every possible permutation in the software settings without success.
The fact that the midi-setup (in utilities) can drive every speaker indicates that the wiring is correct and even that the AV-received transmits the macs signal properly. But somehow, the output from the mac (apart from the setup tool) fails miserably.
I looked through hundreds of forums without success. People suggest using toslink and HDMI connection, but then we need to use two remotes, etc and not sure if that will either.
Apple clearly states MacMini is capable of producing 5.1 ch sound (http://support.apple.com/kb/HT4214)
Hope to get some help and guys in Apple zero in on the issue

After updated software on mac mini with os x 10.7.5 and restart the mouse pointer after about 30 sec. converted to the rainbow wheel and I can't control the computer. The rainbow wheel was runnig 8 hrs and I turn off mac mini by power button, then I turn on mac mini with key Shift and p/w, checked HD. My HD has

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in safe mode.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
for k in /Sy*/L*/Ex*/{,.?}*.kext; do test -f "$k/Contents/Info.plist" && /usr/libexec/PlistBuddy -c "Print :CFBundleIdentifier" "$_" | egrep -qv "apple|Accusys|ArcMSR|ATTO|CalDigit|HighPoint|hp-fax|JMicron|print|SoftRAID|stex" && echo $k; done | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
sudo defaults read com.apple.loginwindow LoginHook | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
Repeat with this line:
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 4
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null | open -f -a TextEdit
Remember, Steps 1-4 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

[Solved] No video in nvidia HDTV after HDMI switching

My HDTV client (Arch64bit,XFCE) goes through a Receiver which can switch HDMI inputs, then to a HD monitor. Until recently, I could switch and find the video still working when I switched back. Recently this changed. The HDTV client also dual boots Win7, which does allow switching. To wit:
HDTV client setup(dual boot,HDMI,nvidiaGT610):
‥Archlinux/nvidiaGT610 ->SwitchingReceiver->SamsungHDmonitor
‥Win7/nvidiaGT610 ->SwitchingReceiver->SamsungHDMonitor
Previous behavoir:
…switching away from HDTVclient then switching back - HDmonitor video works
Current Behavior:
…switching away from HDTVclientWin7 then switching back - HDmonitor video works as expected
…switching away from HDTVclientArchlinux then switching back - HDmonitor video blank (no signal) but Remote desktop works, shows X11 working (putty SSL, vnc Remote Desktop). Requires reboot to restore video with HDmonitor on and Receiver HDMI selected to HDTV Archlinux/nvidiaGT610.

Thanks to Evangelos Foutras (foutrelis) the issue is solved and the Bug FS#44199 - No video in nvidia HDTV after HDMI switching is closed.
The bug...
In xfsettingsd 4.11.2 there appears to be a regression that when a TV hooked up to the computer via HDMI gets power cycled, it stops displaying anything.
It happens via a RANDR event being sent to all X clients when the TV gets turned off.
xfsettingsd thinks that it should switch to an internal output, but desktops don't have one. So when the TV comes back on the bus it seems like it's an extra monitor and xfsettingsd gets confused.
My new workaround...
Unwilling to do any testing on a remote HDTV client for domestic tranquility reasons, I did this…
Dug out an old monitor, searched through the parts drawer and found a DVI-to-DB-9 converter, plugged it in and tested that per description in XFCE Bug 11107 - xfsettingsd resets TV mode to NULL on power cycle.
The problem is (re)solved as video is restored after switching.

Usb keyboard keys stop working after 10 minutes on mac mini osx lion

I am using a mid-2010 mac mini with opitical drive, updated to OS X Lion. Within the last two days I noticed a certain section of my wired keyboard eventually stops working. These are the right arrow key, as well as the 1, 2, 3, zero, period and enter keys. The virtual on-screen keyboard works just fine. I've come home from work and powered the mac and all keys work fine for ten minutes so it can't be that the keys are worn. I was going to take it to Apple Store genius bar but now I can't tell if it's the hardware or the lion software that's buggy.

I had terrible problems last year with the USB ports on my 20" display. They were made worse when I installed a USB 2.0 PCI card in my G5.
At the time the advice I got was that I should avoid using the display as a USB hub. Apparently the ports are only intended for devices relating to the display (whatever that means). Ridiculous if you ask me. I succesfully use my Cubase SX dongle in the back of the display but that's all.

Lion freezes after upgrading to SSD

Hi all,
I just purchased the Mac Mini with a 2.7 GHz Core i7 processor and independent graphics processor. The Mini came with a 750GB hard drive. I purchased separately a 120GB OWC Mercury Extreme Pro 6G SSD, and I installed it as a second drive (using the installation kit from ifixit). I then installed Lion (10.7.2) on the SSD, and made the HD the location for my home directory.
Lion now freezes all the time. I'll be using one app (say, Safari) when suddenly I'll get the pinwheel of death. I find I can switch to another app, but then that will freeze too. After that, I can't do anything; nothing will respond. Eventually, the entire screen turns white. After that, all I can do is a hard reboot by holding down the power button. At first I thought it was Safari, since it seemed to happen most often when having that open. After switching to Firefox (my preferred browser anyway), the problem didn't apper for awhile. But since then, the same thing has happened while using other programs, such as Mail, and it has now happened with Firefox too. The freezing happens randomly: sometimes I've gone several hours without it happening; others, it's happened within a few minutes. It seems to happen when multiple programs are trying to read or write to the drive.
I think it might be related to the SSD based on googling around for similar issues. I installed the SSD the day I got the mini, so I'm not sure if it would have happened on the HD also. (I only booted to the HD a couple of times, to make sure it worked, and did not stay logged in very long.) As bad luck would have it, I started getting the freezing issues just after I had deleted the installation of Lion on the HD, so I can't switch to it to verify that it is the SSD.
Anyway, I was wondering if anyone who has an OWC SSD has experienced similar problems, and if there was anything they were able to do to fix it. Is this a problem with Lion? Would downgrading to 10.6 help (if that's even possible)? I know there have been similar problems with other SSDs, but I thought the OWC Mecury Pros were top of the line.

I got my drive from OWC (6G SSD) on the 20th, so pretty much the same time as you. The machine will hang randomly, usually around 45mins-90mins after a reboot. Seems like we are having the same issue. The solution given to me by OWC was to install the new firmware (http://eshop.macsales.com/tech_center/OWC/SSD). Apparently a new version came out right after we ordered it.
My specs are:
Early 2011 15" MBP w/8GB RAM
Using the Data Doubler from OWC as well, which now houses my old HD (750GB)
Just so you don't waste the time I've already lost, I've tried the following:
Clean install of lion and the using migration assistant
Time Capsule restore
Disabled Sudden Motion Sensor
Disabled hibernation mode
Cleaned my cache using Onyx
I'm going to give the new firmware a shot, and will update here if there are any improvements.
At this point, if the firmware doesn't work, I wonder if there has been a bad batch of SSD drives at the point where we got ours.

Desktop/Finder keeps rebooting after upgraded to Maverick (mac mini hooked up to a home theater system)

My desktop keeps rebooting ever since I upgraded to Mavericks.
Current setup, Mac Mini hooked up to home theater (Panasonic SC-HTB20) that is then hooked up to my Panasonic Plasma TV.
I usually leave my Mac Mini on running and at least once a day when I turn on the TV I can see that my desktop was rebooted. Firefox and Chrome will say that it wasn't shut down properly and if I want to restore my previous session. Also some times when I switched the input to watch TV and switch back, all my windows will be scattered out of place. For example Chrome will be in the top left hand corner to the point that it's almost minimized and I wouldn't be able to move it as well. Only thing I can do is close out these applications and relaunch them. It doesn't appear that the OS actually crashed, but more like the desktop/finder itself crashed. Cause once in a while I will switch back or turn on the TV and the screen will stay black for a few minutes then I'll see the cursor in the top right hand corner. After that I will start to see the desktop and my application start loading. It doesn't go through the regular process of rebooting where you see the Apple logo so I don't think the OS actually crashed but I could be wrong.
For some reason it seems like Maverick doesn't like the home theater system. An almost guarantee way to reproduce the issue is to wait for the home theater to turn off after it's been inactive for a while. If I turn it on the home theater to have the audio coming from it I will see the desktop goes black immediately then the whole desktop reboot process I mentioned above will kick in.
Never had any of these issues on 10.7 before I upgraded to Maverick.
Anybody have any suggestion? I really don't want to format and downgrade back to 10.7.
Thanks

Sounds like a kernel panic.
If you post the report we could have a go at deciphering it.
It would be in /Library/Logs/Diagnostic Reports.

HT3964 My computer freezes after running for about 15 min even after setting the energy saving to 3 hours

My Mac computer freezes after running for 15 min even after seeting the energy saving to 3 hours. Any ideas how to stop the freezing/

Hi Teodorafrombc,
Thanks for visiting Apple Support Communities.
If your computer is becoming unresponsive, you may want to see if specific applications are causing this behavior. Try using the Force Quit menu to check for unresponsive applications:
Using the Force Quit feature of OS X makes an application close, even when it is not responsive.
Important: Normally you should not need to force quit an app to close it. When an app is forced to quit, any unsaved changes to open documents are not saved, so try these methods to normally close the app first:
Choose Quit from the app menu. For example, in Safari, choose Safari > Quit Safari.
Choose Quit by right-clicking or control-clicking on an app's icon in the Dock
You can find the article with these steps here:
OS X: How to quit an unresponsive application using Force Quit
http://support.apple.com/kb/ht3411
If your display is going blank or seems to be going to sleep unexpectedly, try these steps first:
Reset the system
You can reset the Mac's parameter RAM and SMC.
You can find the article with these steps and more information here:

If these steps don't resolve the issue, feel free to reply with more information about the symptoms you are experiencing.

Audio output using HDMI in 2010 mac mini cuts out. Anyone know of fixes?

I have a 2010 mac mini that I hook up with my Samsung C6300 LED tv using an HDMI monster cable. I have never had any issues withn this setup prior to the new Lion software installed and ever since then the audio will cut out for a split second every minute or so (very annoying). I listen to my music library and watch movies through itunes and vlc and I experience this problem with all these tasks. I also have a MacBook Pro (early 2011) that i experience no such issue with while performing the same tasks. Is anyone else having such issues or know of a fix. All my software is up to date so I know that is not the problem. Any help would be much appreciated.
Sincerely
jortiz0221

Lion has created numerous issues for 2010 MacMinis for
lots of folks. However, it seems there is not a "one shot"
fix for everyone.
For instance, I have no issues playing music from iTunes
on my Mini, but iTunes movies stutter some times to the
point of being unwatchable. Yet, other software, PLEX and
XBMC for instance, have no similar issues for me. But there
are others that are seeing the complete opposite from my
experiences. Basically, I think Lion has too many "loose ends"
that are causing such a wide variety and unpredictability in
its operation.
As for VLC, gave up on that long ago as it seemed to flakey
to me and never could get it to work consistantly.

With 10.7 the HDMI sound is not working from the HDMI source on mac mini !!!

Hi,
I bought a mac mini a month ago. The configuration is one display from the mini display port and one TV from the HDMI port.
With the latest 10.6.x version I could enable audio via HDMI.
After Installing the 10.7 version under the sound/Output when I'm selecting output source the HDMI it says "The selected device has no output controls".
What's going wrong ?

PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys."
And it will work

Can you run Lion os and Lion Server os on the same Mac mini?

I'm a windows convert to Mac and I'm interested in running a standard Lion Client, but at the same time running Lion Server on the same Mac Mini (Server Edition). My needs for the Lion Server OS is to handle e-mail, a Web Site, and file sharing between the server to a secondary PC, iPad, and iPhone. But at the same time I wish to dive into the Mac (Apple) experience. I just wish to be able to do this on the same machine.
As a secondary question, is it possible to merge two different iTune Accounts into one? Is it possible to share items purchased on one iTunes account with an iPad that is tied to a different iTunes Account?

1. Yes, but you'll need separate partitions for each OS, or run the client OS in emulation.
2. It isn't possible to combine the accounts, but a single iTunes library can contain content from multiple iTunes Store accounts.

Lion won't install on my Mac mini. Why?

I have a 2 yr old Mac mini with 2.53 GHz Core Duo CPU, 4 GB of RAM and it's running 10.6.8. I just downloaded Lion but the installer says it can't install on my HD. Why not? I cannot find any info about what to do.
Is there some software on my computer that the installer does not like?
Does Lion need a completely new partition to install on?
If so, why is this not mentioned anywhere ?
Thankyou for your help.

Lion creates a recovery area with a minimal version of OS X and it may be unable to do so due to use over the years, and possibly other resizing operations (Boot Camp). It could just need more space, if you only have less than 8gb free. Lion shuffles and merges the two systems when it upgrades. You can burn the image downloaded from App Store by finding the dmg file inside the "Install Mac OS X Lion.app" bundle, dragging it into disk utility, then burning from there.
Otherwise, you can appropriate a MBR/BIOS formatted 4GB thumbdrive, 8GB of either EFI or MBR/BIOS thumbdrive, flash storage device, or external hard drive, and format it, using the restore operation through disk utility to copy the contents of the installer disk to the media. Exposed via the alt key before the Apple logo, should show the bootable media, where you can format over the former installation.
As always, backup your files when upgrading. I recommend if your installion is over a year old to wipe and upgrade if you can't make otherwise the media bootable, using your 10.6 recovery dvd.
If you cannot find an external medium to backup your files before the upgrade, if you need to format via disk utility (Through 10.6 media), you can consider Dropbox as an option (2GB free account).
It's not uncommon for the partition to simply refuse operations, including upgrades and resizing.

After rebooting late 2012 Mac Mini a question mark appears on screen

Hi guys,
After rebooting my late 2012 Mac mini model No A1347 I have a question mark inside a folder always when i try to start my Mac Mini. I understand that I need to reinstall Mac OS X, but I have tryed holding the command, option, R and P keys and nothing happens... I also think the wireless keyboard is maybe not sincronised with the computer, maybe?
I am clueless in how to proceed.
Offcourse, there is no DVD drivein the new mac minis so i can't just reinstall it from a CD.
Please help!!!
Thank you!!

You need to press either the Option key or the Command and R keys. If this doesn't work with the wireless keyboard, use a wired one.
If you can get it booted to a normal Mac OS X system, select that system in the Startup Disk pane of System Preferences.
