    Using 2 displays, connected via HDMI and thunderbolt
    Been on to support a number of times now - is anyone experiencing the same issues?

    BUMP.
    I actually showed this to Apple geniuses when I took my computer to the apple store, and it's still here. In console it says:
    kernel[0]: Previous Shutdown Cause: -128
    I don't know if that's related or not, but maybe helps?

  • Caught in a conundrum while trying to upgrade a Mac Mini (mid 2010) from Snow Leopard to Mountain Lion

    Hi gang,
    I am in a very frustrating position as I try to upgrade my Mac Mini (mid 2010) from OS X 10.6.8 Snow Leopard to whatever the latest version of Mountain lion is. The reason I am doing this is because the original hard drive died and the Mini sat there for 6 months before we decided to get a new hard drive and revive it.
    I installed a new 500GB 7200rpm SATA drive and the problems began.
    First I couldn't get Mountain Lion installed as a fresh OS installation (using both a USB drive and a DVD to no avail). It just wouldn't go. The grey Apple logo/loading screen would come up and just sit there doing nothing while the loading icon spun.
    I then tried installing Snow Leopard (the OS that the Mini came with when it was new). After some messing around, that got done.
    However, a peculiar thing happens when the Mini boots. Everything loads up into Snow Leopard, but although the mouse curser moves, I cannot click on anything or use the keyboard for 4-5 minutes. Then it just work (I am typing this on the Mini). This happens every time.
    Now, when I updated to 10.6.8, I was able to load up the App Store and download the Mountain Lion install app. I clicked it and went through the initial copying of files and then the restart, but after the reboot, the grey loading screen would not progress. I rebooted again and held down the Option key to check out the available boot volumes, and all I saw was the installation DVD I had in there for Snow Leopard and a hard disk volume called "Mac OS X Installer."
    So I booted into the Snow Leopard install DVD and opened Disk Utility to check things out. I did a verify disk and a permissions repair. Interestingly, the first repair I did gave me the message that the ACL was missing from Volumes and that is was fixed. I read something somewhere which talked about the Access Control List and mouse/keyboard issues. But who knows. When I boot back into the Mini as normal I am returned to the fully-functioning Snow Leopard installation, like nothing happened.
    And now here is the kicker: it appears that the Firewire bus is hooped. In the Profiler, when I view the FireWire settings I get the message, "Warning: Unable to list FireWire devices." So I am pretty sure the one thing I cannot do is boot the Mini into target disk mode attached to my Mac Pro and installed Mountain Lion that way.
    So to recap: I can't finish the Mountain Lion installation because the install won't continue after rebooting because there is something wrong with the underlying base system, which might be hardware (FW bus) related. I think.
    Some things I have tried:
    Resetting the SMC
    Resetting the PRAM
    Reparing permissions
    Booting into Safe Mode (doesn't work)
    Booting into Verbose Mode to observe what happens (I get the "Can't load the Bootcache.playlist" error, which I suspect is related to the screwed up FW bus)
    Trying to boot using Internet Recovery (doesn't work)
    Booting into Single User Mode and attempting the "fsck -y" etc. sequence to try and repair the ACL that way
    So I am stuck.
    I guess the question is, should I get an external HD enclosure and install Mountain Lion onto the hard drive that way and hope it works when I put it back into the Mini?
    Any other ideas? I have spent a couple days ******* around with this is am running out of ideas...
    Any advice would be appreciated!

    Addendum: I read on a post here (http://forums.macrumors.com/showthread.php?t=420169) about removing some kext files in order to trick OSX into thinking that there were no FireWire ports.
    I followed the instructions and removed from /System/Library/Extensions/ the following files:
    IOFireWireSerialBusProtocolTransport.kext
    IOFireWireAVC.kext
    IOFireWireFamily.kext
    IOFireWireIP.kext
    IOFireWireSBP2.kext
    I restarted and BAM...Snow Leopard booted crazy fast and the mouse and keyboard worked instantly.
    The System Profiler says "No FireWire ports were found."
    So this tells me that the FW port is probably the culprit and is messing up the installation.
    So how do I hack the Mountain Lion installer and tell it to ignore the FW port, which is obviously quite dead? Or is there something I can do to the Base system that is similar?

  • HT4534 Mac Mini HD Video Conferencing

    I am considering purchase of a mac-mini for video conferencing.  This article (http://support.apple.com/kb/HT4534?viewlocale=en_US) refers to "built in camera".  Of course, the mac-mini has no built in camera.  I would be using my HDTV for a monitor.  Can I use the Logitech c910 & the mini for HD Facetime?

    I also have a mac mini and am using the Logitech C920.  At the beggining, I had issues with its built in mics not working with FaceTime, but I found a solution for the problem and now all the programs that interface with the camera work great (FT, Skype, iMovie, etc).  If you do buy the C920 run into the same issue that I had with the mic not working, here is the quick solution for the problem:
    Cause of Problem:  The Logitech C920 camera/mic operates on a 2ch-16bit integer.  You can verify this by opening "finder + Utilities + Audio MIDI Setup" and then select the HD Pro Webcam C920 and look at the "Input" Default values.
    The Mac Mini's "Built-In Output" and "Buiilt-In Input" formats were set for 2ch-24 bit integer.  Therefore, the default input and output were out of sync with the C920 default format.
    Solution:  Change the Mac Mini's default Output to "2ch-16 bit integer".  You don't need to change the default Input but it doesn't hurt to do so.  Once you do this, the camera and it's built in mics work on facetime and all other video chat applications.

  • Mac Mini wakes up from standby automatically

    Hi,
    My Mac Mini wakes up from standby automatically. Waking up via network is disabled and I use an Airport Extreme, a USB mouse (not from Apple) and a wireless Apple keyboard. OS X version is 10.5.8.
    I have the Mac Mini since about 10 months now. Almost 1 month after I bought it, I had the this problem but thought I am doing something wrong or my wife has forgotten to turn it off
    After a while it was OK. About 3 months later it startet waking up by itself again. I called Apple Care (although the 3 months support was over). They tried to help, but there was no progress. It waked up again and again. After about 1 month it was OK again without me having done anything, no installations, no system updates.
    One week ago, the Mac found some updates at Apple and installed them. Since then I have again the problem! I contacted again Apple Care and again they could not help. They just want me to pay for an extension of the Apple Care package, although they could not help me in this case!
    Now I want to try it myself getting support by people in this forum. I hope there is someone with experience about this case.
    I am not much experienced with OS X, but I will try to answer questions that could help me resolve this problem.
    BTW, I searched for a similar topic and found one ("My MacMini always wakes up from standby") but in that case the wake up feature is activated by the user. In my case this feature is deactivated, as mentioned above.
    Thanks
    Cheers

    Hi,
    sorry for the delay, but I was on a business trip.
    @Bsteely: Sometimes it wakes up immediately because of loosing connection to the keaboard when I send it to sleep. I suppose at the beginning of the sleep mode it into sleep mode, the keaboard connection is closed, then the keyboard "thinks" there is a problem and sends a message to the mini and the mini just wakes up again showing that the connection to the keyboard was lost but established again! This even happened as I had unselected the checkbox "Allow Bluetooth devices to wake up this computer" in Preferences -> Bluetooth -> Advanced.
    But there are also times when the mini does not wake up so quickly. It just wakes up after hours. I had a look at Console.app as you suggested. Very weird to me indeed Well there I found something like "Wake reason = OHC2" or "Wake reason = OHC1". Unfortunately I cannot find older logs there.
    @Boece: Hi and thanks for helping!
    Well, I will try the update as soon as I can. By now I have no external harddisk to first save my data before doing the big update. But I am going to buy one soon.
    Well turning off the monitor is OK, but the harddisk can wake up anytime while the mini is turned on as the OS might need to do something from time to time. And I don't want my computer to consume electricity even if it is such a small one like the mini. I'm a kind of green dude (but not from Mars ). And the sleep mode is interesting for me as I have very often many different Internet sites and some applications running, so I don't need to close them before turning off and open all of them again when turning on the mini.
    Regarding other IR devices: The only IR device now is the keyboard. I even took out the batteries and the mini still woke up over the night!
    Thanks again for your support guys. Please let me know if you have any further information of ideas.
    Cheers

  • Mac mini 2012 - Video Problem (Not HDMI Flickering)

    Hello guys,
    I have a problem with video, it causes to shut down the monitor while is playing Chefville in facebook, i had no idea why would to turn off monitor. It doesn't present any "beep" sound, it seems Intel HD4000 is a defective.
    I waited like 15 minutes when mac mini is cooling, i pressed a button to turn on, the monitor works.
    I think it's overheating Intel HD 4000 cause to shut down the monitor.
    How to prevent this problem?
    Thanks!

    Get Temperature Monitor to see if it's heat related...
    http://www.macupdate.com/info.php/id/12381/temperature-monitor
    Does it use Flash or Java?
    One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
    PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
    Reboot, test again.
    If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
    Check the System Preferences>Other Row, for 3rd party Pref Panes.
    Also look in these if they exist, some are invisible...

  • Mac Mini to Toshiba 32C120U (HDMI to HDMI) problem

    My Toshiba 32" 32C120U is not getting video signal from my Mac Mini. I bought the Mini for my son and this is his TV. I have hooked up the Mini to my older 22" Toshiba and my 56" Samsung with the same HDMI cable and it works great on both. What the heck is wrong with my son's 32" Toshiba? I have called Toshiba customer support and they won't help with my question without a $35 charge because I'm just out of the year warranty . . some customer support that is !!! I really don't know what they would be able to tell me other than thanks for your $35 and sorry we can't help you. I did update the firmware on the TV and the Mac Mini has been completely updated as well.
    I have also tried both HDMI 1 and HDMI 2 ports with his Xbox with success, so both ports work. I have also tried both ports with the Mac Mini and there is "no video signal" on both ports. I noticed that when I hooked up the Mini to the other TVs it automatically selects the best video setting, so there is obviously some communication that happens between the Mini and TV, but that is not happening with my son's TV.
    Any suggestions would be greatly appreciated.
    Thanks in advance,

  • Mac mini, macbook + DVI to HDMI + projector = No soup for you!

    This is driving me nuts!!! I have tried 3 different macs, 4 completely different cables/adapters and they all do exactly the same thing.
    1. I connect the mac to the DVI to HDMI cable and/or adapter combo, then connect to the projector
    2. I get 2-30 seconds of wonderful projector screen usage (it works, picture looks crystal clear)
    3. Then POOF! No projector signal, though it appears mac recognizes the projector.
    I can repeat from 1 using a different adapter and/or cable and I get exactly the same results, but if I re-use the same cable I used previously, I get no signal at all.
    What the $%@! is going on here??? Is Apple black-listing my cables or something??? I'm using everything from cheap-o cables to $$$ cables with exactly the same result.I run this projector with absolutely no problem from a dell desktop via DVI to HDMI.
    For what it's worth, I'm connecting to a LG HS201 projector.
    using Core-2-duo macs either with pure DVI or mini-DVI

    You need to connect via DVI or VGA to your projector.
    I have had Core2Duo Mac minis working with Sony LCD TVs and a Toshiba Plasma via DVI to HDMI cables with no problems. Obviously audio has to be run separately. There have been many reports from others that this works. It should do since both DVI and HDMI support HDCP and both are digital video connections, this after all is why a simple DVI to HDMI cable works.
    What can be an issue is if your trying to do things like 3D or YCbCr colour encoding. However standard video works fine. Another common issue is if your are switching inputs to the TV perhaps via an AV Receiver or if the TV is allowed to sleep or be turned off, in these cases the Mac can see the handshake signal disappear. It is for this sort of situation Gefen makes the DVI Detective+ and the HDMI Detective+.
    Since in your case the common factor is your projector and not the computer or cables it might be it at fault. Early HDMI products did have HDCP handshaking problems.
    People have been using Mac minis as media center computer with HDMI for ages since the Mac mini is small and quiet, this probably goes back as far as G4 models let alone Core2Duo models.

  • Mac-Mini HTPC Video-Out Problems (Component to DVI)

    I recently decided to go with a Mac-Mini as the central-brain of my HTPC configuration, and I was immediately halted in the process of getting things working by my inability to properly output video from the Mac-Mini such that it's even visible on my 50" Plasma TV (Panasonic TH-50PHW3).
    Neither of my A/V Receivers (Denon AVR-3805 & Denon AVR-2805) have HDMI inputs, but both of them have component video inputs for HD content, so I purchased the DVI-to-Component cable linked below to use for outputting video from my Mac-Mini to the Denon:
    http://sewelldirect.com/DVI-to-Component-Adapter-Cable-6ft.asp
    Needless to say, nothing I've tried has been effective in my Mac-Mini being displayed on my Plasma TV??
    Any thoughts?

    From other threads I see that others have tried and failed at this. The adapter cables don't work with the Mini (or other Macs as far as I know). Apparently you need a "transcoder" box. It will apparently take the DVI port's RGB signals and convert them to Y-Pb-Pr component signals.
    The transcoders can also cost a couple hundred bucs. Check out some of the discussions at http://www.avsforum.com/avs-vb/showthread.php?t=824143
    Here is a relatively cheap one that seems to work: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=63079 2&CatId=1430
    Other option is to go with a S-Video adapter http://store.apple.com/us/product/M9267G/A but you will loose resolution.l

  • Mac Mini Audio Intermittent over HDMI, Cuts out with Assertion in kernel.log

    Hello. I've been having trouble with a mac mini (Mid 2011) that I bought on Thursday. It's running OSX 10.7. The Mac Mini is the $599 unit.
    I've got it hooked up to my Sony BRAVIA HDTV (also this year's model) via HDMI, with audio configured to be delivered via HDMI to the TV alongside video. Initially the audio will play through my TV, but after an hour or two of watching something, it will cut out, and there will be no more sound coming out of the TV from the mac. Ultimately, the only way I can fix it is to reboot the Mac Mini. I've also observed that at about the same time sound cuts out, the following error message appears in kernel.log:
    Aug 12 19:21:40 joshs-Mac-mini kernel[0]: Sound assertion "0 != result" failed in AppleHDAWidget at line 3957 goto handler
    Aug 12 19:22:10 --- last message repeated 5 times
    As far as I know, assertions failures usually mean software problems (bugs). I suspect I may be encountering a kernel-level bug in Lion, as this error message is showing in kernel.log.
    The following is a list of diagnostic steps I've taken:
    - I've double-checked the sound output device in preferences. It didn't spontaneously change from SONY TV (HDMI) after sound cut out.
    - I've tried changing output to the internal speakers. It plays sound from the mac mini (as expected). When I change it back to HDMI, still no sound from the TV.
    - I've tried turning off and back on the tv. No effect.
    - I've tried unplugging and replugging the HDMI cable. No effect.
    - I've tried replacing the HDMI cable with two other alternates. No effect.
    - I've tried other HDMI inputs for my TV with HDMI attached. No effect.
    - Note: I've got a ps3 and xbox360 on the TV that has successfully used the HDMI inputs and cables tested on. They've never had this type of problem, so I don't think there's a problem with the TV.
    - I've tried rebooting the mac and resetting the "PRAM" (Command-Option-P-R before the grey screen on bootup). Sound still cuts out after a while.
    - All updates are applied.
    Does anybody else have any ideas about what I could try to fix this? This problem is pretty much a deal breaker, as rebooting the mac mini mid-movie kind of destroys the movie-watching experience.
    Thanks

    I'd just like to jump in on this thread to report exactly the same problem. 
    2011 Mac Mini (the 2.5GHz i5 model) running Lion, Sony Bravia TV, HDMI sounds cuts out after a while with the console error "Aug 15 18:30:25 Mini kernel[0]: Sound assertion "0 != result" failed in AppleHDAWidget at line 3957 goto handler".
    Interestingly, after the error occurs, I can still get 5.1 sound through Plex, but not through Quicktime. 2.0 sound and system sounds all fail until I reboot the system.
    Any help would be appreciated. I would prefer not to have to return the Mini.
    Thanks.

  • Does Thunder bolt port in mac mini support video and audio

    Please let me know thunderbolt or mini display port in mac mini does support voice and video. If I connect this Thunderbolt port to a TV using the mini display port to HDMI cable, will I get both audio and video in TV.

    It depends on the model of Mac mini. If you have the new shape Mac mini - the one with the black circular plastic disk on the bottom, then yes. It can support sending audio and video to a suitable Displayport or Mini Displayport monitor, and it can also support sending audio and video together via HDMI using the built-in HDMI port.
    Older Mac minis do not support this even with a Mini Displayport to HDMI adaptor. The nearest you can get is an adaptor like the KanexLive iAdapt 51 which takes the audio from the speaker out and the video from the Mini Displayport and then combines them to send over HDMI.

Maybe you are looking for
