Any ideas?

Something is messed up with the Disk.
"Try Disk Utility
1. Insert the 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 at the top of the screen. (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. Select your Mac OS X volume.
5. Click Repair. Disk Utility checks and repairs the disk."

My G5 iMac has a screen color problem. The color is green with lines. What can I do to repar this? Sometimes the screen will freeze and I have to reboot the computer and the screen will be normal for up to 5-6 hours and then suddenly changes back to green

Try running in Safe mode. This leaves out some video drivers. Which results in machine not using advanced video hardware.

Unable to install updated flash player to my mac os. Ive empty cache, tried downloading it directly safe mode, and still nothing

unable to install updated flash player to my mac os. Ive empty cache, tried downloading it directly safe mode, and still nothing

Hi Blanca rey
You Can try Uninstalling Flash Player using - Uninstall Flash Player | Mac OS
and Use the Offline Flash Player Installer for Mac (Safari and Firefox) from here - Installation problems | Flash Player | Mac
Hope it helps,
While you try the above suggestion, can you also share the Version of Mac on which you are updating Flash Player and how are you doing it?
Thanks

I cannot swith gmail settings from compact to cozy view in Mozilla, it works fine in Chrome and other browsers, I tried it in Mozilla safe mode and was fine

Just the other day gmail settings in Mozilla suddenly went from "cozy" to "compact" view. Gmail is not letting me reset to cozy in Mozilla, saying it's only for larger screens. However, it does let me use cozy in Chrome.
You had one support forum (https://support.mozilla.org/en-US/questions/972502) and I tried restarting in Mozilla "safe" mode, which allowed me to switch to "cozy". But running in just safe mode is not a solution I can use, so I need to find out what is causing the problem in normal mode that doesn't exist in safe mode. Beyond running in safe mode, there is no other proposed solution here.

'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
*In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
*In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on ''Help'' (or click on ''Help'' in the Menu bar, if you don't have a Firefox button) then click on ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".<br>
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Circle with Line through it on Start-Up, what does it mean?

I am running Snow Leopard, booted off a USB (running Snow Leopard) ran DiskWarrior and I have run Disk Utility off of the install disk that came with my mac. My MacintoshHD is grayed out but I can still repair it and all Hardware tests came back normal. I can't boot into Safe Mode and when I try and reinstall the OS using the disk that came with my Mac the HD is not even visible. After I rebuilt the directory with DiskWarrior I could see the contents of my HD to back some things up but the symbol keeps coming back whenever I try and start up.
Sorry for my rambling but I wanted to say everything I did. Is my HD all done or could it be something else? I have a Time Machine back up and don't have a problem getting a new larger HD as long as that is all I need to do.
Thanks in advance for any help.

This happened to me and the drive was dying, not saying yours is, but mine did. Only time I ever saw that.

Trying to download version 4. Symbol appears with line through it , and I can't install it. Will not work. Have a mac os X version 10.4.

I was trying to upgrade my version of Firefox. Downloaded the new one, got rid of old one as it said could not install because old one existed. Now cannot use either. Firefox circle has line through it.

For to use Firefox 4.0 and newer you need both Intel and OSX 10.5 or newer.
Either you can use the 3.6.17 from http://www.mozilla.com/en-US/firefox/all-older.html or use a third-party build of Firefox 4.0 from http://www.floodgap.com/software/tenfourfox/
note there is no actual 4.0.2 as they decided to get ahead with their own build.

My macbook pro model A1226 doesn't boot up and the screen is black, ived try all reset commands with no luck, or try to go in safe mode, and nothing, please help

It looks as if there's a problem with your GPU. With a Retina machine, that would mean replacement of just about everything, except, perhaps, the flash storage drive.
Print you kernel panic when you go to your Apple Store appointment. I'm betting that it's a faulty GPU but they will be able to diagnose exactly where the problem lies.
Good luck,

Macbook pro wont start up-start up screen has a circle with line through it

When i turn my computer on it goes to the login screen, when i type in my password, an apple pops up on a grey screen, the computer thinks for a few minutes then a circle with a diagonal line through it pops up. Im hoping there is a way to fix this issue without loosing all of my data. i just got a hard drive but havent had a chance to back everything up yet. i know i signed up for some kind of back up with apple where they gave me a key # that i needed to save. i have that number but im really not sure what it is or how to use it. PLEASE HELP!

HT3964 My intel-based IMAC will power on and then I just get a circle that shows it is trying to load and it never stops

After turning on my computer all I get is the white startup screen and the circle that goes around continuously trying to load. What should I do? I have done all the obvious things such as as the power source, unplugged speakers, etc.

Assuming you are running 10.4.11 as indicated in your profile information:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X 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 Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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. Now restart normally.
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.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Won't boot shows circle with line through it

Hi, I just started my Mac Mini and the apple logo turns to a circle with a line through it. Any ideas?

hi guys, hope u all are good?
i Have a problem with my Mac mini starting up...
a Couple of months ago I had an issue with my iPhones syncing to iTunes, I contacted apple support centre for assistance and got it fixed after weeks of struggle with apples technicians helping night after night we figured out that the only way to successfully get the iPhones synced we had to create a new user account which was the last resort we wanted, the. Helped me installing OS X numerous times and did report and all the was to do ( to much to explain). So they suggested that the only was with the new user account but advised that when I have backed up everything I should contact them and the would help me format the hard drive and installing everything onto the Mac mini from scratch, so I did that and got the hard drive formatted and choose the option to install a new copy of OS X off the net via the disk utilities centre on the Mac mini on downloading completion the Mac mini rebooted and started up by hanging with with the startup screen so I switched it off and switched it Back on after a couple of minutes i got the apple changing into a circle with a strike thru?
I Have tried installing a OS X on a external and changing the booting device but the Mac mini doesn't respond anything done on the keyboard?
IS there here any one out there that would be able to advise how I can try and fix this myself?

I've only had my new iMac for a week and today when I rebooted I got a gray circle with a line through it. I've already done the command-r and used Disk Utility to Repair Disk and Repair Disk Permissions... over and over. As a last resort I even reinstalled Mountain Lion with the OS X Internet Recover. No such luck. After it still booted with the gray circle with a line through it.
I was able to use "Scan Image for Restore" to see that all my files are on the hard drive.
What should I do?

Thanks for the response, mende1!
Unfortunately, I also previously tried booting with the Shift key. Nothing. It acted like I wasn't even pressing the Shift key. I tried it multiple times. Sorry, I forgot to say that in my initial post.
I just tried the Option key and selected Macintosh HD (the only option). I still got the gray circle with the line though it.
I've already spent at least 30-40 hours installing all my software and transferring over all my pics and music. I can't "erase the disk and install OS X again".

TS3742 MacBook starts to boot and then has the "no" symbol, (circle with line through it). Tried to reboot in safe mode and got the same thing. Ideas?
