MBP yellow screen on startup

Hi... I have macbookpro 17". I bought it brand new almost 2 years ago. I had upgraded to mountain lion last week and since this week, I get a bright yellow screen for about a second every time I restart my system. Is this a warning of some sort?

Bring it to an Apple store or AASP.

hello,
I have a MBP bought in June 2007
I was trying to upgrade to 10.6.1 and now I got a black screen at startup. Only the keyboard has the backlight on. Nothing on the secreen. What should I do ?
thank you

A place to start might be this article:

It's also possible that you have the NVIDIA problem:
http://support.apple.com/kb/TS2377
If you can't get it working following the steps in the first article, you can contact Apple regarding the NVIDIA repair program.
Good luck!

Too many Yellow screens, too many emails - how to unsubscribe?

I started following a yellow screen iPhone thread after getting my yellowscreen 4S direct from Apple - C39 serial
Replacement No. 1, at Apple Store Covent Garden, also yellow, did not actually swap, although they messed up the paperwork to show I did.
Replacement No. 2. at Apple Store Covent Garden, special order, 'store swap pack' took a week to arrive, also yellow C39 serial.
Replacement No. 3. via applecare by UPS, 'swap packaging' courier was supposed to wait and collect original, didn;t wait, but just as yellow.C39 serial
Replacement No. 4. again via Applecare - I think, by TNT, full retail pack, also yellow, Apple charged for a second phone DNP serial
Replacement No. 5. again via Applecare - I think, by TNT again, full retail pack again, yellow again, Apple didn't have any record of this one until I told them.
At this point Apple who had been previously utterly useless and unresponsive suddenly became very helpful, realising what a mess this all was. Wanted me to give them one last chance, would arrange collection of all 3 yellowscreen iPhone 4Ss, refunds for both phones, and an appointment at Apple store Covent Garden to allow me to see the screen before purchase.
In the event Apple store Covent Garden had no record of what my appointment was for.
It took just shy of an hour to open two iPhone 4Ss and find that both were yellow screen. Both serials began DNP, and all their stock was either DNP or C39, this time the "Genius and Genius Manager were both very helpful, Genius could see the issue at once, Genius Manager was actually colour blind, so could appreciate the issue but not see it for himself - apologetic they could not meet expectation of 'the most amazing iPhone yet' having at least as good a screen as the 4. Welcome to the post Jobs erea I suspect.
Replacement No. 6. at Apple Store Covent Garden, retail pack, yellow screen, serial beginning DNP
Replacement No. 7. at Apple Store Covent Garden, retail pack, yellow screen, serial beginning DNP
Give up on yellowscreen iPhone, revert to 3GS.
All display phones at the Apple Store Covent Garden store were C37 serials - quelle surprise!
On another subject, but the one of the title, I have been inundated with the stream of responses on the previous post I was subscribed to - about 500 not very happy iPhone users at the last count. Each email that arrives tells me,"You are receiving this email from Apple Support Communities. You can change your email preferences in your Apple Support Communities Profile."
Well, I have, and set everything to 'off' but they just keep on arriving. Does anyone know how to stem the flow. I am very sorry for anyone suffering the insipid yellow screen of their 4S, but having decided to go back to my 3GS, I don't want to be updated five times a day..
Thanks for any help

How do I get all users to show on screen upon startup for login?

New MacBook Pro with latest IOS. Yosemite10.10
I got my first MacBook Pro out of the box from the Apple store yesterday...Logged in as an initial admin user...Then I migrated my MacBook Air to it. All three imported users showed. Success!! Then I restarted the MacBook Pro and the startup screen shows only a single login option: The initial admin user login Icon and name that I used on the MacBook Pro just before migrating the other users in from my MacBook Air.
So, I deleted the initial user (I did not need it), so that the other users (already with admin rights) would be the only logical logins that should show upon restart.
Result: The initial "deleted" user shows still, all alone and none of the other users. So I now log in to this "deleted" user, it is very slow to start before the other logins eventually appear after the this delay.
How do I get my users to show at the login screen upon startup and restart?

Go to Settings > General > Date & Time. Make sure your time zone is correct and turn on Set Automatically if it isn't on already.

My macbook pro wont get past the grey screen at startup. Help!!

After doing a run of the mill software update on my macbook pro (running snow leopard) it froze during the "moving items into place" stage. I forced a shut down and now it wont get past the grey screen with apple logo and spinning wheel. I have tried booting from the original DVD but it still freezes. When I boot it in verbose mode it seems to stop at "jnl: unknown-dev: update_fs_block: error reading fs block # 3597880! (ret 5)", the Apple AHCD Disk Queue manager :: set power state is timing out and there is a disk I/O error. I have tried to reset the power manager (not sure if it worked or not) and I have also tried clearing the PRAM (again, not sure of that worked). When I try to look at the hard drive using target mode on my imac the hard drive doesn't come up but the DVD does. I'm concerned that my hard drive is fried. Any suggestions?

It would help to state in your post which remedies you tried that didn't work.
Start here > OS X Lion: If you see a gray screen at startup
If nothing there helped, try Starting up in Safe Mode
Safe Mode deletes some system caches that may help.
A Safe Mode boot takes longer than a normal boot so be patient. Once you are in Safe Mode, click Restart from the Apple menu.
If a Safe Mode boot didn't work, since your Mac has OS X v10.7 installed, restart your Mac while holding down the Command + R keys so you can access OS X Recovery built in utilities. The startup disk may need repairing.
Tip: Hold down the Eject key while starting up your Mac to eject a disc.

IMac G5 running OS 10.4.11. Started playing with a bluetooth speaker (may or may not be related). Now I cannot get past the blue screen on startup. I can get into safe mode. Tried install disc for disc utility and reloaded OS. Still get blue screen.

I have an older iMac G5 running OS 10.4.11. The other day I started playing with a bluetooth speaker (may or may not be related). Now I cannot get past the blue screen on startup.
I can get into safe mode. But no regular startup.
I tried disabling bluetooth, thinking that might be related. It didn't help.
I even tried using the install disc to run disc utility. That didn't work so I reloaded the OS.
But I still get hung on the blue screen when trying a normal startup.
All help would be appreciated.

Try resetting the PMU/SMU and PRAM/NVRAM. You'd need to identify the mode of resetting depending on the model of your G5 iMac. The Apple support sites that would help you for this are –

I hope this solves your problem.

Apple service centre employee told me that they do not have this 14 day offer in India.
And My mac book pro is taken in by Service centre people to run test etc and I will be informed the next day if they accept it as a fault or not ?
I feeling ridiculously bad.

Powerbook freezes at grey screen on startup

I have a 3+ year old Powerbook running 10.4.9 that won't go past the grey apple screen on startup. It pretty much spins indefinitely. I thought it might be a failing hard drive, but I'm not sure after the tests I've done. The drive is 80GB (74.53 GB capacity), with 7.99 GB available space. The drive itself is not as old as the laptop; it was replaced by Apple about a year ago. I have tried the following (with restart attempts in between):
*Zap PRAM
*Reset PMU
*Start up in safe mode (works normally, as far as safe mode is concerned)
*Ran AHT, found bad RAM module, removed module, ran AHT twice and found no other errors
*Startup in single user mode, run fsck, volume "appears to be OK"
*Attach to another PPC 10.4 machine to try to do a backup of files (mounts, works for a while, then crashes the "target" machine (iMac G5 20" 10.4.9))
*Tried to backup to iMac w/drag and drop, migration assistant (both firewire) and via direct Ethernet connection. Always works for a bit then crashes, forcing a manual shut down of iMac
*Startup from external FW drive w/OS X, ran Disk Utility, no problems found on internal HD
*Startup in open firmware, reset NVRAM
*Ran DiskWarrior 4.0, rebuilt directory
*S.M.A.R.T. status is normal/verified
Any suggestions, ideas would be much appreciated. I am really at a loss and very much want to fix this. Thank you.

The problem may be the hard drive is too full. We have found that you don't want your hard drive to be more than 85% full. At last count 8 GB of 80 GB is 90% full.

How to upgrade my MBP glossy screen to antiglare??

I already purchased the MBP 15 however I want to change the screen to antiglare. I know I can install an antiglare film but this hits the image.
How to upgrade my MBP glossy screen to antiglare after I already purchased the MBP? Is it possible to do it through apple?

That would mean replacing the top cover of hte MBP, something on the order of $500...and would have to be done by Apple or an authorized Apple repair or it will void the warranty. You could try talking to an Apple store genius bar person and see if they would do that but it will not be cheap.

Equium A100 black screen on startup

Toshiba Equium A100 laptop
Completely black screen on startup so please don't say go into safe mode etc, because I can't.
I can't see a thing.
Like once in every 100 goes it will come on and I can F12 to boot from the format disk but it eventually freezes before completion.
Video showing what's happening - BTW the buttons you see me pressing are Fn+F5 I've heard that that sometimes works, but yeah, it didn't.

Hi
Look not good dude I think its an serious hardware issue
I checked the movie and cannot hear a beep when the notebook passes the POST (power on self-test). So for me it looks like something wrong with the hardware
But did you try to connect an external monitor in order to check if something would be visible on second screen? Check this
You could also try this:
Disconnect AC adaptor, remove the battery, wait some time (3-5 hours), then connect both parts and try to power up the notebook. If this fails, well in such case have no many other ideas. Ohhh wait maybe you could check the RAM modules. Try to power up the notebook using one module in each slot

Yellow screen on start up

yellow screen on start up

You are very welcome.
I hate having to replace computers, get attached to them, but having the geniuses check this one out will save a lot of frustration. A couple of these past discussions went on and on and on until the person gave in and did what you have done. If it is hardware there just isn't anything on-line help can do about it. Good luck tomorrow and if you have a chance, post the results...we are all fellow users on here and like to hear the resolution to problems.

How to load bios screen at startup?

I'm trying to access the bios screen at startup. This computer has the Mac side and a Windows PC side. I want to open the bios screen in the Windows PC side (if this makes a difference) so that I can change the booting options. Can someone please help!?

iMacs and other computers from Apple do NOT contain a BIOS like Windows machines. They use EFI in place of the BIOS and it is not user accessible. To select which OS you boot into you need to hold down the "Command" and "R" keys while starting up and this will then load the OS selection screen.
Hope this helps

Yellow screen light

my iphone 4s has a yellow screen light,.why like that? while my friend who own 4s also has a white screen, better than mine..

INteresting. i just got an ipad2 2 days ago. (amazing hubby surprised me!) and i guess i'd have to hold it up to another ipad to see if it's yellowish at all.
where was light leaking from....the sides? (trying to picture it)
as far as if it would bug me.......i'm like you and if i notice something that bugs me....then every time i used my ipad, i'd be noticing it. i'd rather not have light leakage, i'd likely just get used to the warmer tones on screen. it's probably better for your eyes anyway. they are probably doing it because it's hard to read on compared to a Kindle. that's my 2 cents.
