Macmini won't restart

My Macmini won't restart so I can't install updates. Also I can't shut down except manually switching off. The shutdown and restart functions don't seem to work. Any ideas anyone?

try booting from your install DVD and repair permissions using *disk utility*.

Can anyone help me get my iMac to reboot? I get a gray "curtain" over the start up screen saying I need to restart my computer but it won't restart. I just keep getting the same message every time.

Can anyone help me get my iMac to reboot? I get a gray "curtain" over the light gray start up screen with a message that I need to restart my computer and to hold the power button until it powers off and then press the power button again to restart. It just does this over and over again and won't restart.

Yeah, as necronym stated, it is a hardware issue and more than likely a RAM problem. Disconnect everything from the computer except keyboard and mouse and try again. If it still happens try removing one and/or swapping your RAM sticks over. Keep trying until you have eliminated all possible combinations. Just put a mark on one RAM stick so you know what have tried. If it still fails to boot properly you should probably replace your RAM, but that is no guarantee of success. Have a look at this link for more info on a Kernel Panic.

Neo2 Platinum won't restart in WinXP

I recently RMA'd a Neo2 Platinum board because the SATA3/4 ports were not being detected during the Windows XP Pro setup. I received the board yesterday and the ports are now detected properly but I've encountered another perturbing problem. I've discovered that the computer won't restart via software. What I mean is after the NTFS format of the hard drive in Windows setup the computer is supposed to reboot on its own to proceed with the installation of the OS but in my case I have to physically press the restart button on my machine to continue with the install. Windows XP will fully install on the hard drive however the operating system can only turn off the PC, it won't restart it. It merely hangs.
I've tried reposition memory sticks, use a different IDE cable, another power supply, clearing the CMOS via the jumper, reverse updating the BIOS twice, and using the safe defaults in the BIOS but nothing has worked. This isn't the first time I've put a computer together and I've built quite a few but this is one abnormality I've never before encountered. I just hope this board doesn't have to be RMA'd yet again.
Thank you in advance for your help. :smiley:

ITunes won't open and won't restart

I've been having some sporadic problems with iTunes (9.x, whatever the latest iteration is), where from time to time it will refuse to quit and then won't restart or reopen. What is the best workflow for troubleshooting this little dilemma?

My IPAD went blank and won't restart...and ideas?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Mac won't restart after updating to OS X Mountain Lion

Mac won't restart after updating to OS X Mountain Lion. Please help?

Like what happens? Is it just spinning?
If you've waited sufficiently long (say 10 minutes) you could just hit the power button which will do the trick. A little more gentle would be to open a terminal window (if you can) and type 'sudo reboot' (without the quotes) and enter your password when it asks. That will do it too.

KT4V & XP2200+, Win2000 Pro won't restart or power down on shut

KT4V & XP2200+, Win2000 Pro won't restart or power down on shut
Just picked up new KT4V and a XP 2200+ for a system build-up for a magazine article story. It also has a Maxtor 120GB 7200 HDD and 1GB of Micron PC2700 (2.5 latency) RAM. Installed Win 2000 Pro on the system (later another HDD will get XP Pro). The Video card is an HIS manufactured ATI Radeon 9000 w/64MB.
Had a few problems on install, got STOP screens a few times. Finally installed and Win 2000 runs fine, EXCEPT that it won't restart warm (like after installing apps or even selecting restart from shutdown) and the system won't power off on full shut down. I get the "It's safe to turn off your system" screen. Checked everywhere in the BIOS setup and 2000 Pro Control Panel for a selection, but there is none!
On restarts, it seems to go throught the "post" and just when the Windows start should come on, blank screen. HDD stops seeking, like doesn't know what to do.
This is also occuring with the Win XP Pro installation, but the OS is even acting flakier!
Latest BIOS has been installed.
I finally spoke to a MSI Tech Rep (took three days of calling and two unreturned messages), with less then what sounded much experience or actual knowledge, he said that it was an incompatibility problem with various ATI Radeon based video cards. I said, WHAT?! You don't design a MB to be compatible with the largest mfg. of video cards! Can anyone confirm this???
I am less than inspired by MSI, folks. And, it will be related in the article I'm writing. X(
Does anyone have any ideas regarding the reason and solutions to the problems??

well i cannot say ive noticed it,a search here only got a single thread re both cards together,i would have expected more
tried http://www.memtest86.com on ram,try one by one if multi sticks
what psu,combined watts ,amps 3 main voltages
seem to recall reading with them they have the extra power intake,and one guy advised making sure card was only thing on it
in device manager whats pc seen as,acpi uniprocessor?
also whats irq sharing look like
try latest bios as well

G5 won't restart or shut down or change startup disc...

(after several updates) my computer won't restart or shut down except manually... which prevents me from changing the startup disc (where all my important stuff is). Option key during startup doesn't give me the startup disc option either.
I'm stuck!
I verified and repaired permissions on both volumes, but can't switch back to the hard drive/OS I need.
If anyone can suggest some helpful info I'd really appreciate the help.

Hi-
Are you using an Apple keyboard? If not, please do so while troubleshooting.
Try resetting the PRAM. Hold CommandOption+PR while starting up. Hold the keys until you hear the second startup chime, then release. The machine should then boot normally.
If this fails to return function, a PMU/SMU reset may be required.
There is a possibility of damaged files within the OS. Boot to the OS install disc, open Disk Utility and run Repair Disk on the Startup volume.

G4 Won't Restart or Shut Down from OS 9.2.2

My G4 867 suddenly began refusing to restart or shut down when booted in OS 9.2.2.
If I'm running under OS 9.2.2, the only way to shut down or restart is to hit the Restart or Power button. If I want to restart and go to OS X, I have to load my OS X Install disk, do a manual restart (as above), boot the CD (holding down the "C" key), and then choose Restart from the Installer menu.
I've zapped the P-RAM and rebuilt the desktop. I've tried booting with Extensions off. I trashed the System and Finder Prefs files.
I tried to install a new OS 9, but the computer refuses to boot from my OS 9 Install disk. It gets as far as a blank desktop and then freezes. I copied a new System folder from another G4 and rebooted from that, but it still won't restart or shut down.
Any ideas?

Hi, Jerry -
Welcome to Apple's Discussions.
By chance do you have a utility named File Saver installed? I think it came with either Norton Utilities or TechTool at one time. If so, try disabling it.
Otherwise, try throwing away these preferences files and restarting -
Energy Saver Preferences
Finder Preferences
Mac OS Preferences
Power Mgt Preferences
System Preferences
Afterwards you may need to redo some settings in Finder's Preferences and in the Appearance and Energy Saver control panels.

MacBook Pro (2006 OS X 10.6.3) won't restart to finish software update (10.6.8)

New hard drive, fresh install of 10.6.3
Tried to update to 10.6.8
MacBook Pro (2006) won't restart to finish the update. It only turns off.
I can turn the machine back on, but the update has not been installed.
Any help will be greatly appreciated.
Thanks.

There may be a redirect issue if an adware software has been
installed by accident or by intent; usually if someone goes to a
web site where questionable downloads of software are free,
there may be (included, added to) the packet you get, adware
or perhaps even malware.
So, if this is the case, the symptoms you say are part of this
experience may be related to an adware or other badware
running in the background. A 'cleanmymac' or 'mackeeper'
can also mess up a Mac computer, & they are not advised.
Several posts to the ASC discussions are about these kinds
of things and many point back to a user going to some web
site and downloading something. A click can do it.
A way to help find some evidence of certain kinds of add-ons
(outside of looking into the Browser's add-ons and see about
deleting those that relate to odd behavior, or badware) such
as adware, one could get and use this free utility & get a
report of general system info, and then post it online to see
if someone can spot some of the characteristics adware or
other malware may have included in the system.
There is another way to get a more lengthy report than etrecheck
as Linc Davis has posted, that uses more detailed effort on the
part of the user, in order to get a larger fuller report.
This is the short and easy way to look for a few clues that may
be addressed through using advice in TheSafeMac guide.
•EtreCheck: (also click on read-more)
http://www.etresoft.com/etrecheck
The report from the above may be helpful along with info in the
site below. Note there are other guides in TheSafeMac, too.
•Adware Removal Guide:
http://www.thesafemac.com/arg/
Hopefully the issue with the browser can be resolved in one
of up to three/four different ways, depending on what it is.
PS: recent updates to some OS X versions, etc do not
include update to Snow Leopard; only later systems.

Good luck & happy computing!

Macbook Pro won't restart while updating 10.6.0 - 10.6.8

Hello all,
I'm having trouble updating my Macbook Pro 13 inch from 2009.
Yesterday I turned my Macbook Pro on for the first time in 2 years and I want to bring some life in it.
It still had the version 10.5.8 which I updated with a usb to 10.6.
Now I want to update my OS X version from 10.6.0 to 10.6.8. I've downloaded the files by clicking on ''software update'' through ''about my mac''.
It now asks for a reboot, so it will install the updates. However, the macbook won't restart.
I click on restart and all it does is show very short a blue screen and then I see my background with only my mouse cursor which I can still move around. All of the applications and toolbars are gone and I can wait an hour and it will still be in the same position. So I have to force the shutdown by holding the power button... And when I turn it back on, it didn't install anything.
Can someone please help me out?
Kind regards!

Manually DL and install the 10.6.8 COMBO update.

CD will not eject and MacBook Pro won't restart

CD will not eject and MacBook Pro won't restart.

Do a SMC reset, that hopefully should get you booting and while booting, hold the option/alt and trackpad button down at the same time. Once a row of icons appears and if the disk hasn't ejected via the trackpad method, then press the eject key on the keyboard until it does.
Click the arrow to boot up OS X.

If this doesn't work, then take the machine in for service.
