Windows starts but Mac OS won't

My Windows XP that I installed via bootcamp works just fine but when I try to start in in Mac OS it stops at the white screen with the apple logo and loading wheel. I've made sure that it wasn't taking a really long time to load because I've left it at that screen for a couple hours and it still wouldn't do anything. How can I get to my Mac OS again?

Try starting up from your Mac install DVD, while holding down the C key, and running disk first aid. You should be able to access disk first aid from the top menu bar.

My dad has a brand new iMac. If he quits an app, this window closes, but the app won't finish shutting down, Force quitting does not work. Once another app is opened, it will not close either. Now none of the apps are responding. Any ideas?

My dad has a brand new iMac. If he quits an app, this window closes, but the app won't finish shutting down, Force quitting does not work. Once another app is opened, it will not close either. Now none of the apps on the dock are responding. I asked him to click on the apple, and drop down to "About this Mac", but that wouldn't open either. Any ideas? If I was at his house, I would call Apple Care in a heartbeat, but am home with my sick daughter,,, Thanks!

For starters, have him open Disk Utility in Applications>Utilities, select the volume (the indented listing) and Verify Disk. If it reports any problems, have him try a Safe Boot by holding the Shift key at startup. This boot will take much longer than usual. It's checking and trying to repair the drive directory, if possible. Once in Safe Boot, have him repair Permissions.
For other Disk repair remedies see
http://support.apple.com/kb/TS1417
Also, have him try a PRAM Reset. At the startup chime, hold down CMD-Option-P-R together, listen for two more chimes, total three, then let go to finish booting.
Also, is he running any AV? If so, have him uninstall it. It might be responsible for this behavior. (There are no viruses for OS X.)

TS3276 the connec doctor sr but mac mail won't connect?

How do you connect to gmail in mac mail when the connection doctor says the connection was successful to the server but mac mail won't connect even after re-inputting the password?

mac mail won't connect to the Comcast POP or smpt servers
So your saying that you have comcast at home and it works fine from this machine?
If you mail works fine at home, then if it doesn't work on the road, it most likely isn't your machine. It is some other problem:
-- with the other network
-- perhaps comcast is preventing foreign mail from working.

Boot Camp: Mac Pro won't start after Windows install

After installing Boot Camp on a Mac Pro dual 2.66 (firmware updated), XP installer went through installation & copying files, then restarted. Went to a black screen with white Windows-style text that said something along the lines of "XP cannot start from this CD, press any key to restart." Totally unresponsive, held down power to restart. Will no longer power up. Have reset the SMC without any effect. Makes a brief sound when trying to start, but does not actually start up.
Is there any known power issue that I might be able to solve myself, or is the supply likely blown?
Mac Pro Mac OS X (10.4.8)

I put Vista on its own dedicated drive, 64GB Vista, the rest as FAT32 to make it easier to share files. I had to remove the OS X drives in order to allow Windows/Vista to install. Once installed, had a black screen and some blue crash screen, until I ran the BootCamp driver updates.
I would try unplugging your drive(s) first and see if you boot from Tiger Installer DVD - or better, boot Apple Hardware Test (hold down "d" on startup from Install Disk #1).

Why won't Firefox 4 on Mac OSX 10.6.7 quit when QUIT is selected? The window closes, but the application remains open necessitating a forced-quit. Until recently it worked fine. I've reinstalled Firefox but the problem persists.

Safari 4.0.3 Starts but won't display any windows properly

Since accepting the update to Safari 4.0.3 this morning, Safari starts but will not display any windows, just the main application menu bar.
Trying new window has no effect and launching a history item either has no effect or safari crashes complaining that the crash could have had something to do with
libcooliris.dylib
I therefore removed /Library/InputManagers/Cooliris but this made no difference.
History flow displays but won't launch any windows and strangely Menu>History>Home opens a window but there are no tabs nor URL nor search bar, but there is only the history bar. The window is all grey including where the page should be.
Trying to open other history items in this window changes the title, but no page contents are displayed.
I also tried reinstalling 4.0.3. from the Apple website, but this made no difference.
Have you any idea what I could try next?
Thanks

Deleted all from /Library/InputManagers and problem solved.
I did have the following:
Cooliris
QuicKeysIM
Saft
DeliciousSafari
SIMBL
TabExpose
Not sure where the problem was, but did find the following in the log after running permissions fix in Disk Utility:

Moving this discussion to the Downloading, Installing, Setting Up forum.
Stephylei you will want to download the Mac versions of the installation files. If you purchased the software from Adobe, and choose the download option at the time of purchase, then the download will be available under your account. You can find more details at Find a download link on Adobe.com.

I remember that with Snow Leopard you could download them from the Apple website.
Cheers!

Read the Boot Camp Documentation while you run Boot Camp Assistant to download the Windows Support Software which was the first step in the Boot Camp Setup procedure.

IMac won't start in mac. Will only start in Windows, option key won't work to allow me to get to mac side. downloaded avast last week. Worried this could be the problem??

iMac was making a strange sound yesterday. I shutdown and restarted now it will only boot in windows vista. I've tried option key that doesn't work, I've tried command R no luck. I've left un-plugged, not sure what to do. I don't even get the white screen like it's trying to load, it goes directly to windows vista, once in windows I can't get anywhere to try and go back. I did download avast the other week, it seemed to be running fine until yesterday. UGH

If you are running OS X "Lion" or later, boot OS X Recovery by holding ⌘ and r (two fingers) while you start your Mac. For Snow Leopard, start your Mac while holding the c key with its original OS X Install DVD inserted in its optical drive.
At the Mac OS X Utilities screen, select Disk Utility. Select your startup volume (usually named "Macintosh HD") and click the Repair Disk button. Describe any errors it reports in red. If Disk Utility reports "The volume Macintosh HD appears to be OK" in green then you can be reasonably (though not completely) assured your hard disk is in good working order.
If you manage to boot OS X, uninstall Avast. Its effect on a Mac has progressed from complete and utter worthlessness to maliciousness.
Be sure to use its latest uninstaller, which will remove it completely.

Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Repair
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

Downloaded windows 7 but won't open bootcamp from usb

If anyone can pleas help me, I followed all the steps to partition my mac hardrive. Everything went well I downloaded windows 7 but now I try to open up usb so I can set up bootcamp and windows 7 will not open any of the usb, it detects them but I cannot open it. I've looked everywhere for a solution but cant find any. Please help!
Greatly Appreciate it!

Thank you David__B! Your suggestion worked perfectly. All the files are correctly associated in both Explorer and Bridge. And it didn't take all that long, mostly uninstalling. The Adobe App Manager very efficiently installs several different programs with very little fuss.
I am not sure, but I think it may have been an old plug-in to Bridge back in the CS4 era that I didn't even know I had that was causing the Bridge file association problems. Uninstalling CS5 after installing CS6 seems to be causing Win Explorer problems, not just for me. Based on this experience, I would recommend that anyone with several previous installations of Adobe CS do the following:
Save your plugins and preference files in a back up file.
Uninstall all the old adobe software.
Run the the cleaner you suggested. (http://www.adobe.com/support/contact/cscleanertool.html).
Install CS6 programs from the CCloud or wherever.
Add your plug-ins back in as you need them one at a time to be sure they work.
If you have already installed CS6 and are having file association problems, just uninstall everything and start at step one. You probably won't save time trying to fix the registry and manually associate file types--- yada yada yada.
Steps 1-6 will give you a nice clean install and salvage only good plug-ins.

Mac pro won't read windows 7 install disc?

My 2007 mac pro won't read windows 7 install disc. My macbook reads the disc fine, so it is not a problem with the disc. It is 32-bit. The apple help line suggested firewire connecting the macbook to the macpro and starting the macbook in target disc mode, but other posts I have read have said that this will not solve the issue. Any suggestions?

Could be. I just rebooted and it read the disc. Unfortunately the windows install got interrupted and I had to reboot, and now it wont read the disc again. Is there any other way to install windows 7 to bootcamp, other than from the disc? Can I use FireWire and target disc my MacBook (the MacBook reads the disc just fine)?

My logic board was replaced on my Mac and now my CS4 will not open. I re-downloaded it, gave the serial number, but it still won't open. It said that the licensing had expired. But this is not the case. Now what?

Firefox won't start, profile manager won't start, but firefox.exe shows in processes list (task manager)

Firefox will not start, even though it is listed in my processes in task manager. Can't get profile manager to start either.
I have tried the following to no avail:
- try to start FF in Safe Mode, doesn't load
- started Windows Vista in Safe Mode, FF still does not load
- turned off Kaspersky AV, FF still does not load
- uninstalled FF, cleaned out user/####/AppData/Mozilla/Firefox folder, as well as ProgramFiles/Mozilla/Firefox folder, and cleaned our Registry manually from all references to Firefox. Downloaded FF 3.6.3, installed. still does not load
- whatever i seem to do, does not fix the problem. When I try to start Firefox, no window appears. I can see the process starting in my task manager. I can "end process" and try to start the program again by double-clicking program icon. Process starts in task manager, but no app window appears.
I am frustrated and have just wasted 2+hours of my night trying to get this to work. Downloaded Google Chrome, unless there is a fix for FF (which I would prefer to use), i will have to switch to Chrome.
I can't pinpoint when this trouble started, but may have been after a recent Windows Update. I already did a System Restore to a restore point about 5 days ago (the oldest one available to me, and I believe that was before the FF trouble started). This has not helped either.
I have run a full virus scan with Kaspersky and a Full scan with Windows Defender. Nothing came up.
Anyone else been able to find a solution to this?
== This happened ==
Every time Firefox opened
== Less than a week ago ==
== User Agent ==
Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.86 Safari/533.4

I found a way to make it work somehow but not really fixing the error... one day when I got really pissed off because FF just won't open, I clicked the icon and killed the enter button, then multiple FF windows appeared. I tried to open it with just a single hit of the enter or double clicking but it won't work anymore, but repeatedly clicking the enter button (mine works with just 3 hits, sometimes 6) seem to open it. And until now, I have no technical explanation for this.
