Slow boot up (stays on white screen for 5-10mins)/bluetooth not available. Help please!

For some reason my iMac boots up really slow and says bluetooth not available which has resulted in me using usb keyboard and mouse. Anyone know how i can fix this?

Disable the Lion resume feature ...
Open System Preferences > General
Deselect: Restore windows when quitting and re-opening apps
Remove any items listed in: System Preferences > Users & Groups > Login Items
Same for HD > Library > StartupItems
Not enough free space on the startup disk can slow startup time.
Click the Apple menu icon top left corner of your Desktop. From the drop down menu click About This Mac > More Info > Storage
Never all free space to fall below 15%.
As for Bluetooth. Open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here: /Library/Preferences
Click Go
Move the com.apple.Bluetooth.plist file from the Preferences folder to the Trash.
Restart your Mac.

Email not opening This is a sudden thing, Email had been working fine for two months then today would not stay open now it will not open at all. after trying to open mail I receive a white screen for a nano second and the app closes

Email not opening on my iPad2 This is a sudden thing, email had been working fine since purchasing the device then today would not stay open, now it will not open at all. After trying to open mail I receive a white screen for a nano second and the app closes.

Have you tried closing the Mail app completely ? From the home screen (i.e. not with Mail 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Mail app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

I have a Macbook PRO and it stopped booting up. When I turn power on it just stays in white screen.

I have a Macbook PRO and it stopped booting up. When I turn power on it just stays in white screen. I have not dropped it anything. Please help.

Try holding alt when booting to select your hard drive to boot into, if that fails, do it again but select the "recovery" partition (If you have Lion or Mountain Lion)

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you

My MacBook pro won't recognize hard drive I put in it. It boots only to a white screen unless I boot to my recovery USB. If I do that then I can select my USB and my external time machine drive in the disk utility, so no problems there. But what do you think it is? It won't recognize any hard drive I put in the machine, so might it be the sata cable?

Boot the Recvoery USB, use Disk Utility to select the internal drive makers namea and size on the left.
Now select erase and select the midde option and click erase, it will take a bit to complete but it's best for the drive.
Now select Partiton tab, click the big box and Options: GUID and then Format: OS X Extended journaled and click apply.
Quit and you should be able to install OS X now with your Apple ID and password.

My iMacG5 will only boot to white screen, gray apple and spinning gear. Help?

My iMacG5 will only boot to white screen, gray apple and spinning gear. Help?
Also not totally sure if it's an Intel based computer, but that's what I recall. Any way to check, since I can't get to About This Mac window?
It's running on OSX Leopard 10.5.4
First symptom = running slowly - then it kind of froze with color wheel spinning - thought a forced shut down would help - help power button til off, then white screen, gray apple and spinning gear.
Have tried...
1. Turn off the computer by choosing Shut Down from the Apple menu, or by holding the power button until the computer turns off.
2. Unplug all cables from the computer, including the power cord.
3. Wait 10 seconds.
4. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.
5. Let go of the power button.
6. Press the power button once more to start up your iMac.
Then try booting from your install disc again.
- No change
And...
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo
appears.
5. Wait for installer to finish loading.
- The fan just got louder.
Thanks for your help.

You need to do an Erase and Install or an Archive and Install depending on whether the hard drive is OK or needs to be reformatted.
Start by booting from your Leopard DVD. The rest is just following directions.
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.

Imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

imac wont boot - i get a white screen with apple logo, and it loads to about 10%, then screen goes black

Hey there mtriest,
It sounds like you are unable to boot the iMac successfully as it keeps shutting down when you try to boot. I suggest the troubleshooting from the following article named:
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/ts2570
Disconnect, test peripheral devices and network cables
Note: "Peripheral devices" refers to external devices other than what came with your Mac, such as hard drives, printers, or hubs that you connect via a USB or FireWire cable.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Disconnect all peripheral devices such as external hard drives or printers (leave only the display, a keyboard, and mouse connected).
Disconnect any Ethernet cables.
Start up your Mac.
If you can start up this way, one or more of your peripheral devices (or installed software related to the device) is probably causing the gray screen issue. Connect one device, then restart your Mac to test for the issue. Repeat the process until you locate the device at issue. Make sure the device is powered if it needs to be to operate correctly. Check with the manufacturer of the device for support or possible software driver or firmware updates that may be available for the device. Try a different cable with the device if possible (such as a different USB or FireWire cable).
Note: If you have multiple peripheral devices and the issue only occurs when they are all connected, but not when each device is the only peripheral connected, see the Additional Information section below.
If you are using a desktop Mac with a third-party keyboard and/or mouse device, and the issue still occurs, try starting up with an Apple keyboard and mouse connected instead. Try starting with no keyboard and mouse connected, then connect them after start up. Also, try a different USB port on your Mac.
If the gray screen issue persists with no devices connected, go to the next section (with the peripherals still disconnected).
Perform a Safe BootSimply performing a Safe Boot may resolve this issue.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
If your Mac starts up as expected, immediately try restarting.
If the Safe Boot does not work, or the restart after a successful Safe Boot does not work, go to the next section.
There is additional information in the article with further troubleshooting if needed.
Thank you for using Apple Support Communities.
Cheers,
Sterling

Hi guys,

i have also tried installing need for speed, here i didn't change anything to the graphics however the problem occurred straight away. white screen then the sound of the games menu and crash. did anyone else have this problem? is there a solution to this? i would like to apologize if this matter has been discussed in earlier forums. However i hope there is someone whom is able to give me a helping hand here. Whats wrong???? thanks ruben

Iphone 3gs shows white screen for a second and reboots.

While I play games, watch videos or do anything, the iphone displays a totally white screen for less than a second and then it reboots. After this it starts normally and then this all happens again after about 10-20 mins.
Plz give me any suggestions to fix it. What is the problem? any hardware prob??

Hello, noyz23il.
I would agree that this is a unique issue. I have attached an article that goes over basic troubleshooting that may help. In this article, see the sections referring to display, camera and blank white screen. If this does not resolve the issue, please see the last section regarding "issue not resolved".

Hi, I can not get my iphone 4 voice over function to work. I turn it on and then it turns off automatical. I ok the message the message stays on the screen for 30 secs or so and then turns it off????

I am unable to turn on the voice over function on Iphone 4. The meesage appears informing me of what the functions does, I press ok and the the message stays on the screen for 30 secs or so and then it automatically turns the voice over function "off" - why???? what am I doing wrong?

I just had this same issue. It occured after I joined my school's Wi-Fi. Suddenly, my home ATV2 and iPhone4 weren't on speaking terms. All five other iphones, ipads, and macs were operating as they should. My phone was not. I tried everything: unplugging and restarting ATV2, deauthorizing all my devices and reauthorizing them, deleting and reinstalling remote app, and countless home sharing on and offs on all devices. Finally, I turned the Wi-Fi off and then on in the setting of my iphone. Boom. Situation remedied. I hope this helps.

My 2007 MacBook pro won't boot up beyond a White screen any ideas what to do?

My 2007 MacBook pro won't boot up beyond a White screen any ideas what to do?

Odd how this hasn't been archived yet.
I'm getting the same thing with my Macbook, but can't boot past the white screen. An Apple store in KS suggested I needed a new hard drive, but I've already put two in there and it's still doing the same thing. I really don't want to buy another motherboard like I had to a couple of years ago.
My choices are either buy a cheap drive to boot from and remove the current one to put into an external case, or save the money by not buying a new motherboard and putting it as a down payment toward a Mac mini.

My Ipod touch just downloaded IO6 but when I press the music button it goes to an entirely white screen for about a minute then reverts to the main ipod screen. I cannot access my music or podcasts. Have restarted both. What should I do?

Computer and Ipod have both been restarted. Video has the same white screen problem. THIS IS NOT THE WHITE SCREEN OF DEATH - just when I press the music or video button.

- Try connecting to comutr and then try to restor.
- If still white screen, let the battery fully drain. After charging for an hour try the reset and restore again.

Hello,
Could be many things, we should start with this...
"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 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, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a 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 completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitirion & use Disk Utility from there.

Slow boot up (stays on white screen for 5-10mins)/bluetooth not available. Help please!
