Mac Mini - Screensaver starting on its own and clock is fast ...

Hi there experts ....
I've got a 4 month old Mac mini
Model Identifier: Macmini3,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2.53 GHz
I've noticed for the past couple of months the clock is 4 minutes fast ....
And the screeensaver is coming on by itself out of nowhere ...
I/ve run disk repair ... Maintenance ... put screensaver to never and even disabled front row screensaver
I've reset pram and nvram ... ANy clues ....?

So even if you put the screensaver to never it still starts on its own?
Also you clock runs faster by 4mins?
I smell an OS issue. Partition your drive and install a fresh OS onto it. If it works(no problem there) then restore the partition into 1 drive. Zero out the drive and put a fresh OS in it
**back it up first
If the fresh OS on the new partition still fails. it could be a hardware failure.

  • Mac mini shut down on its own, will not restart, grey screen, spinning wheel. Unplugged everything, will still not restart. Did safe boot, will not restart after safe boot, only grey screen with spinning wheel.

    Mac mini shut down on its own. Could not restart, chime, grey screen and spinning wheel. Unplugged everything but monitor, still only chime, grey screen and spinning wheel. Started in safe boot, shut Down, will not restart.
    This happened a couple of months ago, unplugged everything and it restarted, now that won't work.

    Hi BDAqua,
    I just did the repair as you suggested. T ran the disc repair, and twice it cam back, the volume macintosh seems ti be okay, I also ran the verify and permissions repair, both came back okay.
    I was actually hoping that they would find something, so they could repair. I shut the computer down, and restated with out holding a key, and I started up great. I'm baffled.  I have moved 20 GB to an external hard drive, as I only had 10% open space.
    I have Tech Tool 6, would you recommend to run a repair check on that, or just leave well enough alone.
    I agree with you on the new Mac's, I have problems with no disc for back up, until they realize their mistake I will stay with Snow a Leopard. This is the first problem I have experienced, so I can't complain. Their last programs are not as perfected as under Steve, prior to his handling over the reins, hope this is not going to be the future we can expect from Apple.
    I will wait to here back as to your suggestion regarding the Tech Tool check
    Thanks for all your help.
    Gratefully,
    Cheri

  • Mac Mini wont start after power outage, and problem copying iPhoto library. HELP!

        So, recently there was a power outage in my neighborhood, the power was intermitent for about 2 hours, during this time my mac rebooted itself several times, but on the second time it rebooted the power went out during boot, then the power finally went out for good, it was back in about 3 hours, but when i finnaly turned on my mac it got stuck at the Apple logo with a spinning wheel and a progress bar that wouldnt go past 40%, when i boot holding command -v it said that there were a lot of errors which were automatically fixed, except for one, "Incorrect Thread records" or something like that.
        I have another partition with Mountain Lion installed for emergencies, the other one with Lion became inaccessible to mountain lion or any other OS X version, but oddly enough, I can access my Lion partition via HFSexplorer and see all my files untouched.
        My main concern are my pictures in iPhoto, and thats about 36Gb of data, I want to backup them to my windows pc by copying the whole iPhoto library package, but HFSexplores for some reason cant copy the folders with date (XX/XX/XXXX) with the /, and it keeps changing them to XX_XX_XXXX and I know that would pretty much break my iPhoto library!
    I googled my drive problem and people said that I need a Disk Utility called DiskWarrior, but I cant seem to find how to to use it, I got a copy from a friend, it was the digital version of the boot disk which need to be burned to a dvd.
    Any help would be appreciated, and sorry for the bad english

  • My MacBook Pro 10.6.8 prompted me of a new itunes update this morning, so i downloaded it. Since then itunes has been starting up randomly on its own, and starts playing the first song on the list. I quit itunes, and it keeps reopening.

    My MacBook Pro 10.6.8 prompted me of a new itunes update this morning, so i downloaded it. Since then itunes has been starting up randomly on its own, and starts playing the first song on the list. I pause the song, and it resumes it on its own again. I'm not joking. So, I end up quiting out of itunes; but, it starts right back up again on its own. After quiting out of the app a few times, it eventually stops reopening; however, about an hour later (or less) it opens again. HOW DO I MAKE IT STOP? I'm just about to delete itunes, because I've had enough of this crap. I hope someone can help. I've restarted the laptop, and it seemed like that fixed it, then itunes started up doing the same thing again an hour later. ituneshelper is unchecked; bluetooth is off; i only have speakers and a mouse plugged in (also charger).

    Read this Apple Discussion Thread and possible solutions. The audio jack has been the main culprit, also certain sync and automation settings including connected remotes.

  • New macbook air caught in loop at start up.  Powers up then gets "dos like" commands on screen and shuts down.  Powers up again on its own and repeats.

    Just pulled the MacBook out of the box.  Turned on the power and on the Apple screen a bunch of lines of command texts appear for about 10 seconds.  The screen then goes blank and the computer shuts down.  It then powers up again on its own and does the same thing again.  How can this be fixed?

    The warranty entitles you to complimentary phone support for the first 90 days of ownership.
    If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

  • Mac mini (intel) frequently shutting itself down and restarting.

    My mac mini has started to immediately power down and restart on its own. I have been using different apps and even just while in the finder deleting old files and reorganizing. I tried a safe boot (holding down shift) and after that I had no audio!? after another restart (regular) it crashed again...I fear that i wont even be able to finish typing this... These crashes are really just the computer shutting down with no notice and resarting on its own... What else can I do here?

    Here is what you inquired about my system.
    1.25gb 667mhz DDR2 SDRAM (self installed)
    I run basic mac apps plus Adobe creative suite 2, quicktime pro, and recently downloaded the 30 day trial of Aperture...
    most of the files I have from the older PPC I used to have are on an external HD pictures and my music library.
    The Mac mini was new when purchased
    devices connected are: linksys 4-port router, D-Link cable modem, Klipsch speakers, a Lexar multi-card reader, Lacie 250GB external firewire drive, 20" Apple cinema display, apple wireless keyboard but a usb mouse (wireless mouse is a battery sucker!), occasionally I attach a panasonic PV-GS300 camcorder - but this has not been attached for weeks and the problem is newer than that.

  • Ipad mini constantly restart by its own

    The screen suddenly displays some black strip then shut down and restart, happens often with some tap and sometimes on its own. The issue starts to constantly happen ever since one time when the device shut down by out of battery. Any help to resolve this issue? This happens about 10 times a day and really gets me frustrated.

    Hi Kokynu,
    Welcome to the Apple Support Communities!
    I understand that your iPad mini is sporadically restarting on its own and know how frustrating situations like this can be. To troubleshoot, I would recommend reading over and working through the information in the attached article. 
    If your iOS device restarts, displays the Apple logo, or powers off while you're using it - Apple Support

  • My macbook pro is running very slow with some strange mouse and window movements. The trackpad is very unresponsive and when responding the cursor moves on its own and/or very erratically. When on safari the window suddenly zooms in or highlights words.

    My macbook pro is running very slow with some strange mouse and window movements. The trackpad is very unresponsive and when responding the cursor moves on its own and/or very erratically. When on safari the window suddenly zooms in or highlights words and looks them up via dictionary. I currently have a wireless mouse connected and I am still having the same problems.
    I fee like I may have a virus or my laptop is perhaps being accessed remotely. All of the sharing options are unchecked.
    HELP PLEASE
    Very worried!!

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
         after the chime press and hold down the OPTION key until the boot manager screen appears.
         Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
         Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

    Found that the second hard drive is broken. I have to go to the apple store to have it replaced.
    I had to press the power button to turn the server off for several times, then the broken hard drive went disappeared. After that, I had to disable the Spotlight. Then the server went back to work normally.
    Now I made a CCC copy of the primary hard drive, and would like to have the server run on the external raid disk (connected through thunderbolt). Does anyone have previous experience with it? Any expectable drawback or issue with this setup?

  • The Character Pallett repeatedly opens on its own and crashes

    Starting this morning I am being driven crazy by the Character Pallett launching unexpectedly on its own and then crashing almost immediately. Then it attempts to launch again, flashes briefly on screen, and crashes again. My crash log shows the same repeated process.[Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: (index >= 0) && (index < [_itemArray count])']
    It's pretty impossible to get anything done. I tried reinstalling OSX combo 1.6.8, but the installer would not see my startup drive as being eligable; I then reinstalled Snow Leopard 10.6 and attempted to update to 10.6.8 that way. But this attempt lead to an error that cancled the install. So now I am running 10,6, but with many apps that require 10.6.8. And the Character Pallett keeps poping up and then crashing even with 10.6. I'm beginning to think it may be a hardware problem, either ram or logic board issue; but I lack the diagnostic skills to figure it out.
    I thought of trying to launch the Character Pallett on purpose, but when I open the System Preferences and click the box that would place the Keybaord icon in the menu bar (which is the only way I know  to get to the Character Pallett) the icon doesn't appear. The check mark doesn't even stick.
    And help would be greatly appreciated.

    Where I am so far:
    1. First I should correct the term I was using. It's tje "Character Viewer" and not the Character Pallett. To access the viewer one normally opens System Prefs>Keyboard and clicks on the box saying Show Keyboard and Character Viewer in Menu Bar. Once in the menu bar, one can access the viewer via a pop down menue item. But I did not have the Keyboard in the menu bar and the viedwer was poping open on its own. I couldn't even get the keyboard menu to appear in the menu.
    2. I took the advice received so far and booted into Safe Mode, trashed the plist item. The viewer popped open on its own still, but did not immediately crash. I could click on the red window controller and close the window. In safe mode I could get the keyboard menu to appear and could select the Character Viewer.
    3. I removed off all my log in items—the only odd thing I noticed was the duplication of iTunes helper. At this point I still could not upgrade from 10.6 to 10.6.8 via the combo updater. So I rebooted normally, but with no log in items. The System Pref for showing the keyboard menu item still did not work. Nor could I upgrade to 10.6.8 with the combo updater. I also tried update just to 10.6.1, but got the same Installer error. But the Character Viewer popup/crash is gone, but so to is access to all the iLife apps that require 10.6.8. iTunes, for example cannot see my iPhone or iPad when they are plugged in via usb.
    So I guess I should thank yuou guys for your help andnow post a new question about not being able to upgrade Snow Leopard. Perhaps there's already been a similar problem posted.
