Mac mini occasionally boots in startup volume screen (SOLVED).

Here is my original message from March 08:
"I've had this problem since I've had my Mac mini (about a year now). Sometimes the startup volume screen appears despite not having any other Hard Drives connected apart from the boot drive (which is the internal Hard drive) and despite not pressing any keyboard keys on startup.
I am using 10.5.2 with the latest mini firmware and am unable to think what could be causing this? I have selected my main hard-drive in the startup disk preferences and have no permissions/hard drive problems (so says disk utility) but the problem persists. It's a minor annoyance but one I would welcome any help with."

Because the original post is archived I thought I would post the answer in a new thread. The answer to this problem was to replace the network cable connecting my Mac mini to my Apple router.
I think the previous faulty cable was causing the mini to do a phantom network boot and that's why the startup volume screen came up from time to time.
Since, the cable change no more startup volume screen problem.
Phew, this has been bugging me ever since I bought my mini. It's nice to know sometimes it's the simple answers that work

I have a similar problem. Whenever I startup my Mac Mini, an icon of the "Macintosh HD" appears in the middle of the screen. It doesn't go away until I click on it. After that, every thing works fine... until I use Safari. If I use Safari long enough, some type of glitch occurs that doesn't let me type correctly; Safari will stop working as it should be, and every time i try to type, some really weird symbols appear, like these ones: ßêÄ©¶¢. The only option I have left is to restart the computer, over, and over, and over again. Please help!!!!

  • Startup Volume screen keeps on appearing - no keys pressed though

    I've had this problem since I've had my Mac mini (about a year now). Sometimes the startup volume screen appears despite not having any other Hard Drives connected apart from the boot drive (which is the internal Hard drive) and despite not pressing any keyboard keys on startup.
    I am using 10.5.2 with the latest mini firmware and am unable to think what could be causing this? I have selected my main hard-drive in the startup disk preferences and have no permissions/hard drive problems (so says disk utility) but the problem persists. It's a minor annoyance but one I would welcome any help with.
    Many thanks,

    Hi and many thanks for the reply.
    The only drive I attach is a firewire one to do time machine backups but I always disconnect it once I've finished backing up (the firewire lead is still attached to my Mac though, just not to the drive).
    The SMART status of the drive in Disk Utility is verified.
    I've taken this Mac back once to be repaired for this problem but they found nothing wrong with it. It is a very intermittent problem though and only occurs rarely. A small, but annoying niggle. I am also using a KVM switch but I didn't have this problem with my last Mac, another mini, connected to the same KVM.

  • Mac mini with a Panasonic 42" plasma screen

    I am new to macs to bear with me.
    I am trying to connect a mac-mini to a Panasonic 42" plasma screen (TH-42PX20)
    According to the Panasonic manual the max resolution is 1024x768 with a 16:9 aspect ratio. The plasma screen connects to the mac with a D-Sub 15P connector (standard PC)
    I select 1024x768 screen resolution and the image seems clear but there are things off the screen (top menu, bottom dash board). Is there a way to change the ascpect ratio? I tried the detect monitors option but that caused the screen to "white out" and never return with an image.

    There is are a couple of programs available to solve your problem. One is "switchhresx". You can download it from "Versiontracker.com". There are lots of posts in this forum regarding its use and setup. Just do a search on "switchresx" and take your pick.

  • Mac Mini Intel boots to blue screen and gets stuck

    Mac Mini running 10.6 Intel won't boot up. I get the chime, then the apple logo, then a blue screen, then nothing but the small rotating circle, which appears and disappears about every 5 seconds (not the color wheel, but the one that just looks like hands on a clock turning.)
    Per apple online help, tried starting up in Safe mode. Same result. No boot. Just blue.
    Per apple help, I started up in Sinlge User mode and ran Fsck from command line (I don't have the install disk). First run of Fsck said FILE SYSTEM WAS MODFIFED. Ran it again, per apple help. Second time, said volume appeared to be OK. Typed "reboot". Same result. No boot, just blue screen and rotating circle.
    Not sure what else to try. Any help?
    Thanks

    Sometimes PRAM seems to retain info from a previous startup disk error condition. There is a small chance that resetting the PRAM might help.
    You can get a replacement for your original OS X install DVD and any bundled apps from AppleCare (1-800-275-2273) for a shipping and handling fee. You will need to provide your Mac's serial number so they can send the correct DVD(s) for your specific model.

  • Mac Mini Server Boot Camp Windows 8.1 White Screen Issue

    Hello Apple Peeps!
    I have a Mac Mini Server 2012 which I have had for around 6 months. I use it quite a lot mainly for Music Production on the OS X side and Graphic Design on the Windows side.
    I recently decided to factory restore it as I wanted to spring clean it and reorganise the way some of my apps were installed. The way I had it set up was it was running OS X on one SSD and Windows 8.1 (installed using Boot Camp) on the other SSD. The way I went about the factory restore was I first used disk utility to erase/format the Windows SSD to Mac OS Extended (Journaled) and then went about the factory restore of OS X onto the other SSD as normal (following instructions from the Apple website).
    The issue I am having now is that my newly installed Windows 8.1 (used solely on a single SSD) is hanging on a white screen for quite a long time before the Windows splash screen shows up, where before when I would boot or restart into Windows there was no white screen and it would go straight into the Windows splash screen and load to the desktop very quickly.
    So my question is...
    Why do I get this prolonged white screen before the Windows 8.1 splash screen appears? How can I get rid of it? It was certainly not present on my previous installation. Can anyone advise me what the computer is doing during this time so that I can do some further research into a solution.
    What I have tried already....
    1) PRAM & SMC reset.
    2) Setting the startup disk to Boot Camp in both OS X and Windows 8.1.
    3) Reinstalling Windows 8.1 through Boot Camp.
    MAC MINI SERVER (LATE 2012), 2.6GHZ QUAD CORE I7, 16GB RAM, 2 x 256GB SSD, OS X 10.10.2, Windows 8.1 (Retail), Boot Camp Assistant (5.1.3), Covered By AppleCare.
    I would really appreciate some help with this ;-)

    I have right clicked on each SSD in Device Manager and selected the option 'Properties' from the drop down menu, which brings me to this window...
    I'm not sure where I can find Device Attributes, I have clicked on each of the tabs in the window above, as far as I can see none of them mention AHCI enabled or anything similar. Thanks for all of your responses by the way...much appreciated!

  • Unexpected power off now mac mini want boot up pass the grey screen

    i have a mac mini the power went off when it came back on and i tryd to cut mini back on it only went to gray apple screen them goes out the monitor says not supported i need to get class assignments off of it.

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.   
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • Blank screen on Mac Mini running Boot Camp 3.1 with XP SP3

    After upgrading from 3.0 to 3.1 of Boot Camp I now am getting a blank screen after Windows finishes it's loading screen.
    Booting to safe mode works.
    I have tried uninstalling 3.1 and reverting back to 3.0, but the issue remains. Reinstalling 3.1 again also gives the same error.
    I uninstalled and reinstalled 2.1 (from a older system disk I had around) and the issue seems to be resolved however the refresh of items and windows on the screen are very slow.
    I have isolated the issue to the NVidia drivers, however I am unable to find any besides the bootcamp ones that seem to work. I've read through the forums and people have mentioned downloading drivers for other models but not the Mac Mini.
    So, two questions that would be very helpful in my quest to fix this:
    1) Anyone know where to get the latest working Nvidia drivers for the new Mac Mini (besides bootcamp)
    2) Anyone have a good utility or know of a good cleanup utility to get rid of all the previous nvidia drivers all over the place and in the registry? I read about a few, but it would be nice to know which ones actually work with bootcamp/xp, etc.
    Thanks for any assistance on this!
    - David

    I fixed it. All I had to do was change the output to the Cirrus audio device instead of the ATI.

  • Mac Mini just boots to grey screen - help!

    My trusted mac mini a1176 (intel 1.66GHz) has always worked fine but now it just has a grey screen when it starts. There is no chime, and if I leave it long enough a picture of a file with a ? in it appears.
    The events leading up to this could have an effect, I am not sure. The original hard drive had a mac and a PC division. I took this drive out 6 months ago and fitted a larger one. This larger one had a carbon copy of the mac part of the original drive made on it. I did not put the PC division on it. All worked fine since. Today I wanted to boot up the PC partition on the original drive so I put the old drive in a USB enclosure, plugged it in and then in settings chose to boot from the PC part of this drive. This is the last thing useful the mini did. It just went to grey screen on restart. So then unplugged the external drive, still no boot. Since then I have tried.
    Pressing differen buttons on restart
    Putting leopard instal disk in drive ( this is he os I am using)
    Disassemble mini and put he original disk back in
    SMC reset
    Take out extra ram
    Disconnected every other peripheral.
    I use a apple wired keyboard
    A dell mouse (I have a Bluetooth apple one)
    Any suggested next steps would be warmly appreciated? Would the logic board just go like that? It seams a bit of a coincidence!
    Thanks and sorry for he spelling, this is from my iPhone.

    Here is YouTube video of what the screen is now doing.

  • Mac Mini 2011 boot camp freezes on loading windows screen.

    I bought my mac mini 2011 server, have upgraded it to mountan lion and mountain lion server and wanted to install windows on it. I have microsoft windows 7 professional OEM system builder edition on a dvd, a LG portable super multi blue rewriter, a corded mac keyboard with number pad, a HP mouse, and a hdmi monitor. I have not upgraded any features on the mac, it is original.
    I updated all software, well except a printer driver that I don't have the printer of anymore, and ran boot camp. I tried to partition my entire hard drive for it, however that did not work. I then tried to partition half of the first hard drive and that did not work either. I tried unpluging the mouse and keyboard and it still won't work. I bought the copy off of amazon and it appears to be legal. I just always get stuck on the "Windows is loading" screen. The loading bar, a white band across the bottom of the screen, always goes across the whole screen once fast, then makes it's way to the farther left side of the screen and then hangs there indefiniteley.
    Any suggestions? more questions about the situation?

    Mini mini, there are problems with mini and esp. server version.
    What I think others have said: cannot use OS X Server, had to use Mac OS X client
    External LG is not supported. Doesn't come with an internal SuperDrive though does it?
    The system builder is fine.
    Just one story (there are others, I need to collect all the "Mac Mini Tips" together, I can't remember and keep them straight otherwise.
    HDMI audio in Windows 7 64 bit 
    reinstalled the Intel video drivers and audio worked immediately.
    My config:  2011 Mac Mini 2.3, Intel 3000HD video
           .   .       upgrade to 8GB ram
    Samsung 8000 series LED TV connected with HDMI
    Memorex external BluRay writer(USB only power)
    After partitioning drive with boot camp and reboot, install Windows 7 with install wizard.
    When asked whether to allow automatic updates say 'no', then complete installation and run boot camp tools for Windows.
    Because the network driver gets installed prior to the Intel video driver, Windows will install the Windows Update Intel video driver which breaks HDMI audio.
    When auto updates are off, the Intel video driver that is correct gets installed last. 
    HDMI audio works with this driver.
    Apple should install the Intel video driver first and it would solve this problem.
    I now have full blown 3D BluRay support on the MacMini with TruHD audio, fantastic!

  • Mac Mini Slow Boot. Leopard

    I have a Mac Mini 5 months old running Leopard as delivered.
    Recently has started taking 5 minutes to boot.
    I see no obvious troubleshooting tools I would expect with a Windows PC to assist.
    What are the likley causes?
    What tools can I use to debug problems?
    I have installed all up to date software, but not any firmware updates if indeed such things are available.
    MAc is new to me so apologies if this is obvious!!

    If it is primarily slow in the blue screen part of the startup process, then the system has already located the boot disk. The boot disk is simply the drive with macOS installed on it that the system uses to start up on, and is of course normally the internal hard drive.
    You will have received a DVD with the mini that has a version of MacOS on it that can boot the system, primarily for use if and when you need to reinstall MacOS because the installer is also on that same disk. Also on this DVD, there are a few basic and simple utilities for checking and testing the system, but these are rarely, if ever, needed.
    First thing to do is open System Preferences - it's the square icon with the cog-wheel design near the right-hand end of the dock. You'll see a number of preference 'panes' in there (the equivalent of Windows control panels) which allow you to set a range of appearance and behavioural defaults in the system. Most are pretty self explanatory of course. Open the Startup Disk pane, and after a second or two once the panel shows the available startup volumes, you should see your internal drive listed, and probably also 'network startup'. Select your internal drive and click the restart button. This is just to make sure that you have your internal drive set as the startup so MacOS doesn't need to go searching for it.
    Once the system restarts after that, and assuming the restart is still pretty slow, open Disk Utility (open your hard drive, then the Applications folder, then the Utilities folder - it's in there) and select your internal hard drive on the left. Then click 'Verify Disk' to check the drive if functionally OK. If it completes verification with no errors, next click 'Repair Disk Permissions'. This will ensure that the drive is healthy and all the user and system rights are correct. Errors with these can cause boot problems (and a great deal of other issues too).
    If that doesn't resolve the problem, disconnect the USB hub (and all the devices connected to it) and reboot the system to check it isn't a USB issue. USB can cause lots of issues on both Mac and Windows systems, so it's always a good thing to troubleshoot with the minimum of devices connected.

  • Mac Mini 10.6 Server startup disk size increase problem.

    Mac Mini 10.6 Server shows system startup disk sized 50GB with 20GB free. Disk utility shows partition sized 500GB with 470GB free. How can I increase size of startup volume without complete reinstall?

    Is the disk partitioned?
    Boot the operating system DVD, use Disk Utility from the Utilities menu (second screen of the installation process, just before you start the actual install) to ake a complete backup to an external disk, make a second backup (in case there's a problem with the first), wipe and repartition the internal disk (using Disk Utility), and reload.
    You'll want to consider whether you want to mirror the two disks within the box, too; to set up RAID-1 across both of the 500 GB drives in the box.  That mirroring can be established when you're wiping and repartitioning the disks.

  • Mac Mini shuts down during startup after update

    I've got a Late 2009 Mac Mini running Snow Leopard Server. Occasionally, it takes me awhile to restart after updates, so this could be due to the most recent update or possibly the combination of the last two...
    I went into my office, saw that there was a Safari update and decided to let it do its thing. When I came back 30 minutes later, my machine was off. I turned my machine back on, got the gray Apple screen with the spinning cog and the progress indicator for the update. A little over 10% through, the progress indicator reset. No biggie, I figured. Second time it got to the same point, it just shut down. Nada. When I restart, it does the same thing.
    I've tried resetting PRAM.
    I've tried resetting SMC.
    I've tried booting in safe mode, but that isn't working at all – just does the same thing as when I (fail to) boot normally.
    Everything but one of my screens and my keyboard is disconnected. ****, I even tried booting without either one connected (I just waited to see if it would turn off), and it failed.
    Can't think of or find anything else.
    Anyone?

    Humm.. you'll need to startup from your System Install Disc to test, repair or restore from Time Machine.
    Some options for Starting up from your Install Disc include:
    1. in an External Optical DVD Drive.
    2. from another iMac in Target Disk Mode.
    3. from a copy on a Thumb Drive or External HD.
    It's to bad that you are using Time Machine on the second HD instead of a clone with Carbon Copy Cloner - Home or SuperDuper! that you could boot from for testing, repairing and/or restoring.
    If none of the above helps?
    There is one good thing about a Mac Mini, it is much easier to tote into the local Apple Store or AASP than an iMac. see > Apple - Support - iMac - Service FAQ
