SMC Reset Procedure on New Mac Mini

I received my new HDMI Mac Mini yesterday. The machine works fine, however, the fan runs constantly (and VERY loudly) from the moment it boots no matter what I am doing (all I have done is install iWork). I read that a SMC reset might be necessary to calm the fan down. I used the old Mac Mini reset procedure but it didn't change anything. Does anyone know if there is a new SMC reset procedure for the new Mac Mini? Or, does anyone know other reasons the fans would spin up immediately to full speed and never change?

So just to be clear, you unplugged the system from the AC feed, then held in the power button for about 5 seconds to bleed off any residual charge, and only THEN did you plug it back in?
But the fans can also go into high gear if the internal temperature is too hot. You can only cool a device to the ambient temperature of the environment it's in. So if you're down in the south of florida, or one of those places where it gets to around 100F in the shade, you can expect to hear the fans going so the system doesn't melt down.
Another possibility is that you have a bad temperature sensor cable, or it somehow didn't get connected. If the system can't get a reading from the temp sensors, it defaults to putting the fans into high gear, which is the safest option. That one you don't want to attempt on your own. Have someone at an apple store or local AASP check for that.

  • Bootcamp will no longer boot after deleting partition #3 of my new Mac Mini.  What happened?  Was it the way I tried to reclaim the HDD space for Mac?

    Here's my dilemma.  I have a new Mac Mini - a week old.  I installed Windows 7 on it using Mac's Bootcamp assistant.  I then set up and configured my Windows 7 world and everything worked fine.  No issues logging in between Lion or Win7 via the restart/option key procedure.  Well, yesterday I split my Mac HD partition one more time to create a third partition (was created as an "extra", e.g. possible future partition for another operating system).  After creating it, I then decided that I didn't really need it.  So I deleted it in Disk Utility and attempted to drag the Mac HD partition line downward so as to "fill in the gap" and reclaim the lost hardrive space.  It seemed as if I could reclaim about 1 gig or so, but I figured...oh well. 
    Well, the Mac HD partition seems to work just fine, but now I've noticed that I can't get into the Bootcamp partition anymore.  It wont boot.  If I try to verify the partition [doesn't even give me "repair" as an option), then it fails and gives me the following error message: "verify volume failed.  invalid request."  When I go to the Startup Disk option in my System Preferences section, it displays the bootcamp partition as a folder and not as a drive anymore.
    I'm assuming that I messed up some permissions or lost some vital links during my attempted resizing/reclaiming of harddrive space.  How do I fix this without having to reload either all of my Mac info or all or my Win7 info?  I'd hate to consider the last two days of my life loading this crap up a complete loss. 
    Thanks in advance!

    Thanks for checking in, BDAQua.
    Problem solved.
    In the docs that came with my Powerlogix accelerator card, I found this sentence buried:
    "If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, so you will have to boot from the Firmawre Update CD and perform this process again in order to boot in OS9."
    The "process" it's referring to is the process of setting up the NVRAM for booting into OS9 from the CD.
    Fortunately, I was able to find the disk, and it worked as expected. I can now, once again boot into OS9.
    Conclusion: My (unadvised) attempt to load Leopard on this old machine apparently reset the PRAM on the accelerator card and cleared the NVRAM code for OS9 boot. Although I did attempt to reset the NVRAM via Open Firmware, it did not reset it on the accelerator card.
    So, thank you BDAQua, for your "Ah yes" . . . that's all I needed to steer me in the right direction.

    Just purchased a new mac mini 3GHz Intel Core i7, with 16GB ram version 10.10.1. With it i purchased a new wireless keyboard. All of a sudden I was not able to use the #1 key. I thought I had a defected newly purchased keyboard. I pulled out my older wireless keyboard, and the same thing happened. It must not be the keyboard if it happened to two different keyboards. I have a habit of restarting my computer, when things don't work, I find it helps, and sure enough, everything works. Today, it happened again. Does anyone know what is causing this to happen?

  • New mac mini - updated 10.5.7 then no display at all

    Just purchased a new mac mini 320gb. Set it up via dvi to hdmi to display on my Sony Bravia W series 52" LCD. All worked good and was very happy with the crispness of the image etc. Then did system update to 10.5.7 and now there is no longer any signal to the TV at all. I've tried 2 HDMI cables, reset the SMC and drunk a few beers - and none of this activity seems to have helped. Very frustrating!!
    Recent forum discussions have not highlighted identical issues - anyone had similar?
    Cheers

    My mini did the exact same thing when I upgraded to 10.5.7 on my Sony Bravia XBR4.
    The mini would try and start up as I could see the gray screen with the Apple logo and the spinning wheel on the Sony screen. Then the screen would turn black.
    I used my other computer to connect to the mini using Screen Sharing. Once connected to the mini, I set the screen resolution to 1920x1080 and a few minutes later the Sony screen finally showed the mini again. Why it took a few minutes, I have no idea.
    Something apparently changed in 10.5.7 but mine is working again.

  • New MAC Mini w/OSX Lion - will not boot from USB or external optical drive when attempting to use BootCamp to install Windows 7?

    The University recently purchased 6 brand new MAC minis for deployment in classrooms I support.  I am attempting to create a dualk--boot environment comparable to our existing computer systems, only these machines wil be running MAC OS X Lion and Windows 7.  After following the procedures outlined in the BootCamp on-screen prompts, and attempting a few techniques I found in the tech support user-base, I am still unable to get the MAC mini to boot up from the USB flash drive, or from an external optical drive, so that I can complete the installation of Windows 7.  When using the Boot option key at start-up, all devices are displayed suggesting that they are being properly recognized, however the computer boots to a black screen with an error message indicating that "No bootable devices are  found - press any key to continue." I am able to boot into the computer's internal drive, but not from any external devices.  I fully expected that the semi-automated BootCamp procedure properly prepares the USB device for booting, and for installing the Windows 7 OS.

    Meh, with the price they take for a drive in Denmark, I don't think it's worth it... They take around 160 $ for the drive (that's the cheapest MacBook drive I could find), and I am not even sure that's the one I need.

  • New Mac Mini+Superdrive+windows 7 - Will it work?

    Looking at updating my father to the Apple world, thought I would get him a Mac Mini, and use Bootcamp to install Windows.  As the new Mac Mini doesn't have an optical drive (I have a MacBook Air Superdrive), if I use the external one to install Windows, will it install properly?  Does the Mac Mini have the drivers for the SUperdrive?  Any thoughts?  Thanks in advance.

  • New mac mini won't accept dvd's/cd's in the combo drive

    Hello friends:
    i have a new mac mini that I bought about 2 months ago (Intel, 2.0 ghz). Everything was working fine until I went to put in a DVD today. The combo drive won't accept a disc. It's not that it won't read the disc, it physically won't suck it into the drive. Instead it just sits there. If I try and push it in, nothing happens... it just bounces back out at me as if pushed by a spring. And, no, there isn't already a disc in the drive.
    Can anyone suggest how to get my combo drive to work again?

    Hi jrm27,
    I have an older Mac Mini 1.66 GHz, but I haven't seen this problem.
    I take it that the disc does go in a little way. I would think that that rules out that the drive thinks there's a CD already in the drive. I know that when I have a CD or DVD in the drive, the little doors (they're really there) are closed and won't let me insert a 2nd CD.
    I presume that you have restarted your system since this started to occur?
    When the system is rebooting, hold down the mouse button. This is supposed to force eject a CD. It might also trick your system into thinking there's no CD there, or resetting something.
    Try different types of CDs or DVDs, just to make sure that there's not something screwy with the media that you are using. Try an old-fashioned music CD or something.
    Are there any sounds the drive makes?
    David

    Hi surroundsound,
    you can't put more partitions on internal HD once you install winOS with Boot Camp.
    The sure fix is to delete the windows partition (with Boot Camp Assistant, not Disk Utility), then getting rid of the extra partition (with Disk Utility).
    then you can re-install your win& (recreate the win. partition with Boot Camp) - don't add any partitions after.

  • Itunes delete my music in my iPhone 4 iOS 6.1 I'm new mac mini

    ahen connect a iphone 4 ios 6.1 to new mac mini all of my music vidoe was delete , after i sync to the new mac mini , how can i restor , i did a bucup.

    I'm having similar issues just lately. The phone itself is very slow to respond to the touch, just scrolling between home screens is a chore at times. There have been about 2 incidents of random vibration from it. Closing home screen folders takes a couple of attempts. I find that I'm also having delayed keyboard responses when typing messages to my contacts.
    Also, sometimes when I press the sleep/wake button it takes about 30 seconds to register it and actually lock or wake up.
    Have you experienced the backlight failing to light up? Like if I get a message it flashes up then goes black straight after and when you press the sleep/wake or home button it lights up again but very very dimly and you have to press the sleep/wake button as if locking it and then press it again to bring the screen up properly?
    Mine is also on 6.1.3(10B329), model MD245B/A, obviously not Jailbroken, carrier unlocked from Vodafone (but that was months and months ago). Roughly 17gb of storage space left.
    This has only started happening in the last 2 weeks. Haven't tried the reset or anything yet though.

  • New Mac Mini Backup

    Just bought a new mac mini i7, do i have to buy mountain lion from app store to get a back up image in case i want to reinstall. or is there a way to reset to factory settings.

    Welcome to the Apple Support Communities
    Go to  > About this Mac and see Version. If it's 10.8.x, you have Mountain Lion, so you can reinstall OS X for free with Internet Recovery. However, you can't download Mac OS X from the App Store because your Mac needs a special OS X version that it's not available in the App Store

  • Boot Camp bug with new Mac Mini?

    OK, so I have used Boot Camp now for years, on a variety of Mac platforms, and I have always been able to set it up and run Windows, including Windows 7 64 bit.  That is, until I purchased my new Mac Mini i7 (non server version) with the WD 750GB internal, with 8GB ram.  As the new models no longer offer a built in SuperDrive, I purchased a Pioneer external Blu-ray drive and have it connected via FireWire 800.
    I have a brand new retail Windows 7 64 bit installation disc and have downloaded and burned the Windows 7 drivers to a CD.
    I followed the instructions implicitly, but always hang on the reboot that should go into Boot Camp and begin the Window 7 install. Instead, I get the dreaded "Boot disc not found. Please insert a bootable disc and press any key" error, from which there appears to be no return.
    Anyone have any ideas or is this just a known bug?

    This same message was displayed in my MacBook Pro yesterday when I partitioned the HDD, however in my case I hit the "Quit & Install Later" Option as I planned to install win 7 later. When I rebooted my Mac to my surprise it had defaulted to my DVD drive and could not find the disc (obviously, since I wasn't planning to install it). I remember that in SL this issue was not present. Ultimately, I had to hit the option key to boot back into OSX Lion and reset my Macintosh HD as my start up disk via system prefs.
    As for your case I would suggest hitting the "option" key during start up and see if your Mac can recognize your Windows 7 disc. If it recognized select it with the keyboard arrow keys and when it is selected hit the "return" key. Then the Win 7 DVD should boot and then follow the instructions of the Windows 7 Installer.
    My suggestion is to fill a bug report to Apple via their feedback section:
    http://www.apple.com/feedback/macosx.html
    As far as I know Bootcamp 4.0 is extremely buggy, yet I do think that OSX Lion overall is a very stable and snappy OS, I noticed that my system performance has not been that much impacted by it very much. My boot times went up by 3-4 seconds longer than SL and shutdown times went up by 1 sec only, as for app launch time they have remained the same. Hopefully further updates to OSX lion will address these and other issues.
    Good Luck!
