White Screen Upon Pause

Video and everything else works fine, but whenever I pause the viewer, the viewer goes white. Any suggestions?

In the course of editing, you probably pressed Shift-W which places the Viewer (or Canvas, depending on which is selected) into Alpha mode. Since your video file has no alpha channel (transparency) all you're getting is a white screen when paused.
To switch it back to 'normal' (aka RGB mode), press Shift-W twice. (pressing they key combo only once will produce a red tint over your footage - that's RGB+Alpha mode).

HOW DO I CORRECT A WHITE SCREEN UPON START-UP?

HOW DO I CORRECT A WHITE SCREEN UPON START-UP?

Festus,
I'm getting you have a MacBook rather than an iMac, if so you may want to request to have your post moved to the correct forum. However please read Gray screen appears during startup to begin troubleshooting your problem.
Also when posting please do not type in all caps, it is considered shouting. We can "hear" you fine.

Does anyone know about a white screen upon start up?

My daughter has an older MacBook and we have upgraded software. She tells me that she has a white screen upon start up each time she turns on (boots up) the laptop. I tried to boot the machine up to see what IOS version she has but can't get past the white screen. I trried moving the mouse and pressing arbitrary buttons to no avail.

Try booting from an installer DVD. If that works OK, then reinstall OS X.

White screen upon booting

Hi I need some help my macbook pro 15" (os lion dont know what version) went to sleep and ran out of battery, when i charged it and tried to start up it wouldn't so i did a force shutdown (press power for 10 secs), now when i reload it loads the bar on the bottom for about 1cm then the bar disappears and the white screen with the apple logo stays with the loading sign spinning again and again.. doesn't do anything after an hour or so i've given up.
I have read through numerous previous posts, from what i have gathered,
I have run the "command s" and $fsck -y and tried to fix the disc but it shows:
** /dev/rdisk0s2
** Root file system
Executing fsck_hfs (version diskdev_cmds-540,1~25)
** Checking Journaled HFS Plus volume
The volume name is Macintosh HD
** Checking extents overflow file.
Invalid leaf record count
(It should be 577 instead of 579)
** Checking catalog file
Incorrect block count for file bounds
(it should be 1 instead of 0)
Keys out of order
(4, 12661)
** Rebuilding catalog B-tree
** The volume Macintosh HD could not be repaired.
**** FILE SYSTEM WAS MODIFIED ****
So what do I do now I know B-tree is a corrupt file. I dont have time machine and haven't backed up my files in 6 months. its actually due for backup this weekend!
I went into Disk Utility to run repair disk but it says "Disk utility cannot repair this disk. Back up as many of your files as possible, reformat the disk and restore your backed-up files.
My question is, how do I recover my files. Once I get my files I can reformat
Any suggestions please. Thank you so much! PS. I'm a comp illerate so please simple slow steps in explaining

After 4 nights and numerous research hours later I have finally fixed my corrupted Mac HDD. (Macbook Pro early 2011, OSX Lion 10.7.2)
I don't want all this effort going to waste so I'm going to give some step by step instructions on how I managed to fix my MacBook Pro. Idiot's guide because I am not that great with computers..
Presenting Issue:
When powering up Mac, unable to load the OSX. It goes into a white screen with the apple logo with the loading sign spinning below. A grey bar below that shows up and starts to load but disappears not long after. The loading sign continues to spin but nothing happens.
Diagnosis:
- Shutdown computer. Press power button, then press "command S" straight away and hold, you will hear the chime and wait till the terminal screen loads (this is a bunch of white text). Then release buttons and wait till it stops. Type "FSCK -Y" (without the ""). Wait for it to run. If the disc is broken it will try to repair itself. If that works then you are good. You can type "shutdown -r now" and restart computer it should load normally.
- If you have my problem it should say something along the last few lines of:
** Rebuilding catalog B-tree
** The volume Macintosh HD could not be repaired.
**** FILE SYSTEM WAS MODIFIED ****
This means the computer was unable to repair the HDD for you.
If you have backed up your computer then you can skip this next part. If you haven't (like me) then you will need to retrieve your files from your corrupted HDD.
Note: If you have a B-tree error you will not be able to use firewire (below) to access and erase your disk, nor will you be able to unmount your disk. When you try it will tell you it cannot be done. Also you will not be able to reinstall OSX onto the corrupted HDD - if you go into "command R" restore (below below), the disk will be greyed out and say it is in use and cannot be booted.
Resolution (Retrieve Data from a unbootable Mac):
- You will need to buy a IEEE 1394 800/800 9pin to 9pin firewire cable. If you live in Australia, I found one from Dick Smith for $10, where other electronic stores sell between $20-$60.
- You will also need your friend's MBP (or any other Mac that has a 9pin firewire port).
- Plug both MBP on their power supply. Turn the normal MBP on. Plug the firewire cable into both computers. Then press the power button once on the unbootable MBP and press T straight away and hold until the normal computer detects the broken MBP as a external HDD (it shows up as a yellow rectangle shape icon). The broken computer will also display a screensaver with an icon moving around.
- The normal MBP will detect your Mac HDD but it will display an error message informing you the disk is corrupted and unmodifiable. Press ok to ignore.
- You can now access your unbootable MBP as an external HDD. It is the icon on the desktop "Macintosh HD". Copy the files you require. Then press the power button once on the broken MBP to turn off firewire transfer. Unplug firewire cable. Done !
Resolution (Installing OSX Lion)
- You will need a previously partitioned disk on your broken MBP which is not corrupted which you can erase and use to format OSX Lion or a 3.5" external HDD. If you are lucky enough like me who likes to keep a random spare partition you are in luck. If not plug the ext HDD into the USB port with the MBP off.
- Turn on the MBP and press and hold "command R" until you hear the chime and until the grey recovery screen loads (I think this works if you have osx lion or mountain lion. If you have snow leopard you will need to insert installation disk instead).
- Select language and select reinstall a new copy of OSX Lion. This will take you to the installation screen. You will need internet access so either use airport or plug a direct ethernet cable (quicker d/l speed, faster installation).
- Select installation site as the spare partitioned disk or the external HDD. It will then download OSX Lion onto that disk (took me 2.5 hours), and install OSX Lion (took me 30 mins).
- Bazinga! OSX Lion installed.
Resolution (Erasing Unmountable Macintosh HD)
- Once your OSX Lion is installed and your computer is up and running again, you can now go into disk utility and select your Macintosh HD. Press "Unmount", it will go grey, and then select OS X Extended (Journaled) format, press "Erase" to do a 1-pass erasure of the HD. This should take a few minutes max and then check if your Macintosh HD is empty. TADA!!! New HDD.
- If you are crazy like me you can spend a good 7 hours and perform a complete 7-pass erasure. To do so go to advanced settings and change the erasure type.
Resolution (Copying OSX Lion to Macintosh HD)
- Now you can reverse the action by restoring the OSX Lion into your original Macintosh HD disk, and then erasing your partitioned disc.
- I'm sure you can just copy the disc and then erase but I'm not risking any more issues so I'm doing it the hard long way.
Fixed. If I took it into Geniuses they will tell me my HDD is dead and needs replacing. No way when I trust my gut instinct that it's a corrupt HDD.
Good luck guys. I'm now off to get my much deserved and deprived SLEEP! Hope this helps!!

White screen upon booting. Already took it to the "Genius Bar" and they wouldn't even look at the computer.

I have an older model MacBook that all of a sudden just stopped working. I originally got the apple logo but it would load no further than that. After reading other posts I tried the Command-Alt-P-R reboot option. It worked a few times and I was able to reboot the computer but now it just loads to an all white screen. I took the computer into the Genius Bar at my local Apple store and the "genius" did not even try to turn on the computer or look at anything. He just suggested I try to sell it on ebay for the parts and purchase a new computer. He said it was pointless to do anything else. I was pretty disappointed by this response especially since he didn't even look at the computer at all. Just hoping someone has a suggestion as to where to go from here!
Thanks for the help.

Put your install DVD into the optical drive (CD/DVD drive) and reboot. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option Key until the Install Disk shows up) until the apple shows up. That will force your MacBook to boot from the install DVD in the optical drive.
Or if you are running 10.7 Lion, boot from the recovery partition (Command +R on boot) and use Disk Utility to repair your OS 10.7 partition.
When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it. When it comes up is your Hard Drive in the list on the left?
If it is, then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've clicked on the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions. After repairing use Startup Disk from the same menu to choose your hard drive for restarting from your hard drive.
If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

Showing hidden files white screen upon restart

I put in the command to show hidden files and restarted my iMac. It only shows a white screen. Completely blank. How do I fix it? It runs on Lion and has a Time Machine backup.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
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.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to a pre-2013 Mac Pro tower, not to any other model. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

Flashing ? folder on white screen upon start up

i have a 2008 macbook unibody and when started up i get a white screen with a flashing ? folder. I have tried some suggestions i found here, like holding the c button as well as holding the option button. when i hold the option button i get a flashing spinning globe on a hard drive. nothing else happens, i cant choose a drive or only thing, but i get the cursor. someone please help. oh and i dont have the install/reboot discs either.

The flashing ? mark can mean several things.
One the starutp disk is failing or has failed.
A flashing question mark appears when you start your Mac
You mentioned holding down the Option key. Theoretically, that would prompt the Startup Manager window where you can select the startup disk but if that didn't work, then you may be out of luck.
If the startup disk has failed, you wouldn't be able to repair the startup disk using your install disc anyway.

White screen upon start up

Hey sorry if this has been answered but im not in the mood to go scrolling through dozens of pages to find what im looking for.
So here goes. Today i decided it was time to set boot camp, however before i could do this i had to defrag as my imac is around 20mouths old and the drive looked a bit messy. (note : it worked absolutely fine) Defrag finished and my computer was back to normal use, i postponed setting up bootcamp for a day and shut the imac down. When i rebooted later the typical white screen appeared with the happy spinning wheel. HOWEVER underneath this was a loading bar that i have never seen before, this loaded to about 10% then went back to the start and got to about 30/40% before the computer shuts itself down.
WHAT IS GOING ON? please help im a university student a i desperately need tis to do my study.
PS i have tried the trick of unplugging (that is mentioned all over google) it didn't do anything.

Did you (or your defrag utility) verify the integrity of the drive before defragging? If not, sounds like your drive was probably damaged in the process. Try [repairing the hard drive with Disk Utility|http://support.apple.com/kb/TS1417]. Most likely this will not be adequate to get your computer back up and running - you may need to go so far as reinstalling the system - but it's a start.

White screen at computer start up

friend's computer has a white screen upon start up. We have tried at the rebooting steps in manual. screen is now white with a blinking folder icon with a question mark in the middle of it. What does this icon mean, and do you know of any other steps before we go to apple store?

It means your system cannot find a system folder to start from. Try these suggestions at below link.
Good luck

DV4-1275 with white screen

About a week ago the screen on my wifes DV4 went white. We could increase the amount of brightness on the thing, and we could hear windows running, but just a white screen. I hooked it up to my PC's monitor and it looks like the VGA port is working fine.
I took the thing apart, checked connections(all good), and figured that the LCD was shot. I bought a new, OEM LCD and replaced it today. It didn't do a thing. It still starts up just fine, with a completely white screen. If I hook the thing to my monitor, the laptop seems to be working fine.
Not sure what to do at this point.

Hi there, I have the same problem, my dv4 has a white screen upon boot, how did you rectify the problem?

White Screen and No Bluetooth. Imac and Apple support, Terrible

I have an imac that is less than 6 months old. It now white screens upon start up and takes for ever to load, and then does not display any bluetooth icon and no mouse will be noticed via bluetooth. I re-installed the OSX, became anxious and lost all my work creating a new install after the re-install did not work. I have protection cover and they did the usual over the phone in the way of the obvious key commands. Nothing changed. I was then told someone would call me back in half hour, no one did. I did not use Time Machine for any back up and now have a new install with none of my old software and still the same problems. I used to build PC's for professional people and never a problem. I use a Mac and it falls apart after 6 months? I know that quietly imac has had lately many issues swept under the carpet. The main culprit was the cheap hard drives installed. I would imagine now after what I have seen that this hard drive made by Hitachi is just as bad.
The main key commands, un-plugging cables and so on does not work here. I have nothing but a large screen that is in all respects nothing more than a cheap machine with a nice brand name. I think it is wrong that we pay for machines that are by chance, not exactly ready for people to actually use in the real world? To many people have the same problem and when we ask if we can have our warranty extended, we are told "No". I think this is unfair. All we ask is that Apple makes machine that, "Work". Ok, I know that some will always have the odd problem but here with this situation, one need only google white screen to see the cover up. Do not make machines with cheap parts for top end prices and make us feel as customers as if it is either a, shock that it has happened as Apple is far to cool, or that we are to blame due to our lack of understanding.

Have you tried booting from your restore disk and checking the disk for errors?
Is this one beep you hear or multiple? Could be bad RAM.

White Screen when FCP5 is paused

I have recently installed Final Cut Pro 5 onto my MacBook Pro for use with both HD footage from a Panasonic HVX200 and standard DV footage. When editing, I am not able to see frame by frame in the viewer or canvas. Instead I get a white screen everytime the video is paused, making edits very difficult and frusturating. Therefore I can see the video and hear the audio when it is playing, but the screen turns white when paused. Does anyone know the reason for this? Please help! Thanks

I'm having the same problem with the white screen on my 32 gb Touch. I connect it to my Mac Book Pro at night look at it in the morning and the screen is completely white. I have to hold down the center button and the top button to get it to restart and when it does the battery is in the red. I've exchanged it twice since September. I sent the last one to Apple and just got a cheery email from them telling me that they can't find anything wrong with it and they're sending it back with notes on troubleshooting.
I absolutely hate it when they pretend that this is the first time they've heard of such a thing. But I have AppleCare and I'm just going to keep taking it back until I get satisfaction.

Why upon turning on my mac its just a white screen ?

why upon turning on my macbook pro it freezes on a white screen and dosent change ?

Welcome to the Apple Support Communities
It's possible that your Mac has forgotten the startup disk. Turn off the computer, and then, turn it on and hold the Option (Alt) key until you see all the bootable devices on the screen. After that, choose the OS X partition and OS X will start up. After starting, open System Preferences > Startup Disk, and select your OS X partition.
Also, try doing a PRAM reset > http://support.apple.com/kb/HT1379
