10.9.2 won't complete install, won't restart stops at grey screen, multiple attempts, last overnight, have to shut off my holding power switch, when back on, says computer needs to restart in updates.

I cant get the update to complete, keeps hanging with a grey screen and have to manually restart, completely frozen at this point 3 times now.

Having the same exact problem on my iMac 2010 21.5". Tried countless time and different ways to try installing the update and still ending up with the same result (grey screen with software updater at top and it just stalls out on doing anything). Now my computer with not shutdown or restart without holding the power button.

IMac G5 won't boot. Attempted to install Leopard,wouldn't allow, then would not reboot in HD's Tiger, nor from OS DISK IN DRIVE. OPTION START shows both OS 's, but still won't boot from either. Grey screen , spinning pinwheel for 5 minutes, then shuts off

When I tried a custom leopard install(omitting all but canon printers), a window appeared that " I could not install OSX ON THIS DISK." I tried a full install again and a window appeared stating that " the HD was not formatted properly, would I like reformat in hfs extended HFS EXTENDED journalled and ERASE THE HD?" I use disk utility on leopard to reset the iMac to restart from the original Tiger OS on the HD, & that was when it refused to boot. During 1 attempt I even tried to boot with the C key held for many minutes to start fron the Tiger OS disk but the iMac wouldn't start the cd spinning. I did hear that familiar FIRMWARE UPDATE CHIME! but I was not upgrading firmware as none was downloaded, and Leopard did not tell me it required a firmware update first, when I attempted to install it. So: I get the chime when the power button is pressed. Option key finds the HD TIGER AND THE CD 's Tiger. I van choose both. But neither boots. Starting with the C key held doesn't boot. In every case the startup grey screen appears with the grey startup pinwheel, this continues for many minutes. Then it shuts itself off. Help help help. My son has Graduate School papers in progress, and I just fried his iMac. Thanks to all.

Simon:
Thanks very much for the suggestions! I tried your method of booting to the install CD while holding option (alt), and then running Disk Utility to repair the disk and the permissions. Even though it still told me the drive didn't need repairing, there were more permissions that needed repairing when booting this way (as opposed to when booting while holding the C key.)
Anyhow, after doing this, my computer restarted just fine from the hard drive. Mail works now and I'm about to try repairing permissions one more time, then shutting down and restarting again, this time without doing it from the install CD. Wish me luck...
OK. It booted up perfectly this time. I'm not quite sure why that worked, though. Anyone care to illuminate me as to why booting while holding option (alt) let Disk Utility do what it needed to, while booting while holding C didn't?
At this point I'm just curious. My problem has been solved!
Thanks again very much, Simon. I really appreciate it, mate.
Cheers,

Hello m.goo, and a warm welcome to the forums!
To eject the Disc, hold the Mouse button down, (or what passes for it on a Laptop), while powering up, if you also hold the Option key down at the same time it should eject & give you a chance to insert your install disc & wait for it to shw as a Boot option.
"Try Disk Utility
1. Insert the Tiger Mac OS X Install disc , then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, *you must select your language first.)*
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
Then Safe Boot , (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it finishes.

My Macbook pro often won't start up since I installed Lion, and I have to shut it down using power button. My desktop icons don't appear and the dock won't open. I only have the little circle of color spinning endlessly. What's wrong now!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

I can't install Firefox 5. It downloads & starts the wizard. I follow the prompts till it says it needs to restart the computer 'to complete a previous upgrade of firefox' . I say yes and it restarts and there is no sign of firefox and no error message.

The very first time I tried this there was a red message that flashed on the screen too fast to read it. I have Windows 7 and AVG. My son's computer also has Windows 7 and AVG and his upgrade went without a hitch. It deleted my old version of firefox (3.6.12) so now I'm using IE. Windows installed a lot of updates just before I tried upgrading firefox. I have tried turning my firewall down. I have gone to the file in downloads and double clicked it and it does the same thing. It always says it needs to restart the computer even though I have closed all other applications. Should I just give up and try reinstalling an older version of Firefox? Thanks

It is probably because you are not properly closing Firefox. Restarting your system would make sure that Firefox had terminated, but you do not have to do that.
To properly close Firefox on Windows systems, use
:File > Exit or "Firefox:" button > Exit
When you get the message "Firefox is already running" it is too late, and you must force termination of Firefox through the Windows Task Manager before restarting Firefox. Windows 7 has a keyboard shortcut to save you a step "Ctrl+Shift+Esc" then on "Processes" tab, select "firefox.exe" and use the "End Process" button. More thorough would be to right-click on the "firefox.exec" and choose "End Process Tree".
You would find firefox.exe in a Mozilla folder in your program files, but y0u would not want to delete it there, you would need to use the Control Panel which you have already identified and do it from there -- but generally you would not need to do that, and there is nothing in what you have posted to indicate that you should. But if you did do that, then don't let the install start Firefox for you as you would want to use you existing desktop icon or method of starting Firefox, and should decline having Firefox install start Firefox for you. When the install starts then invoke Firefox in your normal manner. This should eliminate problems of creating a new profile rather than using your old profile.

Why can't I update to OSX 10.9.1? I restart my computer and the AppStore still says I need to restart to install. I've tried many times with failure.

I restart my computer and the AppStore still says I need to restart to install. I've tried many times with failure. I have restarted manually, through the appstore, and on the Apple Menu.

If your computer is looking for a server, it sounds like you might have a problem with your Internet connection.
Chrome is probably trying to warn because .exe files can contain viruses. Chances are, if you're connected to mozilla.com and have https: (a secure connection), you don't have to worry about getting software with viruses or other malware.
Is your account on your computer an administrator account? Are you able to install other programs without limitation? If not, you might not have administrative privileges, which will make it hard to install things. You can download things, that doesn't require admin privileges, but altering the computer's operation by changing programs requires such privileges. If you do have admin privileges, I don't know what could be causing your problem.
Don't know if I've helped you or not, hopefully someone else knows specifically to what you refer and can answer, if my suggestions didn't do anything to help

Whenever i try to update my macbook pro, it downloads then says I need to restart my computer. I restart the computer, and everything just freezes. When my computer eventually turns back on, its not updated. other apps i try to download dont download also

First, do the following:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
When you complete the above re-download your OS X upgrade (not sure which one that is, but I assume Mavericks.) After the download is completed re-install it. Hopefully, this time it will do what you expect.

Firefox wont run says pc needs to restart to complete installation, it never does- same message when i try to uninstall

firefox will not open. when I try to uninstall it I get a message that says
PC needs to restart to complete previous firefox installation
but when I reboot I get the same message, I can not access Firefox in any manner

Glad it helped, <br>It probably would have been better to get to the root cause of the problem but if it is working again that is the important thing.
You could have problems at some later date, and one of the most important things is likely to be your collection of bookmarks. It will be worthwhile regularly making manual backups of those, and keeping them somewhere safe outside of the main firefox folders, if you ever need to do a full uninstall and reinstall, including deletion of old firefox data at least you will then be able to reinstate bookmarks. see [[Backing up and restoring bookmarks]]
As an example of what can easily go wrong, and an add-on recommended by another poster see [https://support.mozilla.com/en-US/questions/787020 thread] ''"I deleted by mistake bookmarks by uninstalling the previous version of Firefox beta 4.011b... Is there anyway to recover them?" ''
leading to http://www.pikey.me.uk/mozilla/#bb as a method of automatically backing up bookmarks and profile information.

Have you tried a soft-reset : Press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider if it appears), after which the Apple logo should reappear and it will hopefully reboot.

HI .. I have a new macmini 2.5 Ghz 10.7.3 Lion, had a problem today ,it froze so I could not shut down using mouse or tablet. used the power switch, when I tried to restart I got audible 'beeps' from it.

HI ....I have a new macmini 2.5 Ghz 10.7.3 Lion, had a problem today ,it froze so I could not shut down using mouse or tablet pen. used the power switch, when I tried to restart I got audible 'beeps' from it. I managed to restart it but kept getting a message come up on one ot the dual screens ' restart using the power swich to turn it off , then press it again to restart.'
This worked okay , but now it just keeps freezing whenever I start it up. I thought the issue could be my old Epson Expression 1680 scanner not being compatible , so I have unplugged it. I also had a look at the new memory I installed when I got it, but this seems not be the problem.
It is connected up to an Eizo Flexscan S2231W using a cable straight into the HDMI input , the other monitor is a small Acer using the VGA into Thunderbolt port.
When I turn the Eizo screen on first and then press the power button on the mac-mini, I hear the chime then the screen flahes the 'Digital no signal' message on and off for about 30 seconds , then the monitor comes on as normal. But it is still freezing up on me after using it for a while and I am having to use the power switch button to turn it off again.
Can anyone help please.

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

The computer need to restart! (After upgrading to ver 10.6.2)

Lately, I've upgraded my Imac to version 10.6.2 in order to install the new magic mouse, after a while my Imac got this problem: The screen suddenly turns to half black and there is a notice :This computer need to restart..." I have to hold down the button to turn the computer off and then turn it on again. It happens very random but could be 4 or 5 times a day.
So have anyone of you has the same issue? What the reason and how to fix it? Pleaseee...

You are experiencing a Kernel Panic as seen and described in Apple doc. HT1392. If not, disregard.
Bad or incompatible RAM is, more often then not, the cause of most Kernel Panics. It could also just need to be reset.
