I have a macbook pro retina display mid 2012 model. When i boot up i hear a chime but screen is black. I wait a few min to allow it to finish booting up with a black screen. I close the mac book for a few minutes to let it fall asleep. When i open it , screen works and im on login screen.

It's my understanding that the start up chime you get when you start up on any Mac,c an NOT be changed because that sound is in the firmware. Cool.
That being said, is there anyway to add/hear your own custom sound clip AFTER that?
Does any one know how to do it?
I just replaced my LCD. It was working fine, but now just stopped working. It's a mid-2009 A1286 15in Macbook Pro.
The computer itself works fine and I tested it using an external monitor. I can FAINTLY make out the display on the screen, so I'm guessing it is a backlight issue? Don't mid-2009 don't have display inverters?
I also tried resetting the pram and SMC.
I have a Macbook 2009 that wont turn on. When you press the power key you hear the normal boot chime but no picture appears.Â
The laptop was given to me without any hard drive, so I installed a blank 250GB HDD. The HDD has no OS on it, and I am not sure how it is currently formatted as it is new.Â
Even when I use an external screen and regardless of whether a HDD is present the macbook does not show any sign of life on the screen or external screen but still chimes.Â
I know it would be a good idea to boot with restore discs etc, but even if no OS is present surely the screen should still come on and display the gray and apple logo? I did all the resets and holding button configurations on startup, such as reset PRAM.Â

I'm doing my best not to panic here but I'm sure you can feel my pain. I got up this morning, made my coffee and opened up my MBP to start my day.
I can hear that start up sound but the screen is completely black. Nothing. It was fine yesterday and I didn't do anything different when I closed it to put it in sleep mode. But now it won't wake up. I pulled the battery, let it cool (seemed a little warm since I just started it)....still black screen.
Can anyone provide any advice on how to fix?
I've got a nasty issue with my 13-mo. old MacBook.
I'm pretty sure it's a dead logic board and possibly a dead hard drive, which I really, really, really hope not as I don't have backups of everything on the drive. I just upgraded to Leopard this past week and did a clean install so not all of my stuff is setup yet.
Power adapter and battery are inserted. All 3rd party peripherals and RAM have been removed.
MacBook does not chime at boot. The screen flickers, but stays black. If I hold down the power button then try to let it boot the light on the front right flashes constantly (like when it's sleeping but a faster pace), like a turn signal on a car. I can hear the cd-rom drive whining but everything else is dead silent.
I've done everything here with the exception of calling Apple.[URL]
I've also tried FW Target Disk Mode, but the MacBook drive does not show up.
I've done everything I can think of and I'm out of ideas at this point.
Additionally, there's a cd-rom (Tiger Restore CD) stuck in the drive. Holding down the mouse button during restart does not eject this CD. Where is the force eject button (I see no pinhole)?
I have business documents, emails, etc. that I HAVE TO get off this hard drive. How can I do it? I don't have a 2.5" drive enclosure but if that will solve the situation I will pick one up asap.
My macbook air 2013 doesn't start.black screen. It gives starting chime but then nothing.

I am having a problem with my 2009 Mac Pro. It fails to boot. There is no chime and the screen wont turn on;stays black. It wont boot off of the system dvd and I even tried installing an HD that has a good version of the the OS on it. I also tried booting from the DVD with no installed drives to rule out one of the internal drives doing someothing funky. Nothing happens at all, the HD or DVD will spin for a moment and then all is dead.

It installed ok, but after restarting it just sits on a black screen and goes nowhere. It plays the on chimes and churns the DVD drive, but then nothing. BTW, the computer didn't come with any installation discs
View 1 Replies View RelatedThe latest iMac model. When I click on the power button: I can hear the Hard disk and the DVD drive spin up. The screen stays black. The startup sounds plays half way through the first time, like its being cut off. After the first startup chime has been cut, the chime keeps playing in a loop. The computer doesn't come any further than that.
I have tried: Unplugging all peripherals, with the same result.
SMC reset: Unplug power cord and hold power button for 5 sec. PRAM reset...
It seems like the computer does not even get to boot and ignores all keyboard input. I also tried booting from the DVD drive with the installation disk. But I can't get any further than the repeating startup chimes.
Upon start up I hear optical drive checked, then get a start up chime but the screen does not light up. I have shut down by holding down power button for 10 seconds also pulled battery and A/C power.

So my girl friend was using my IBook G3 and shut it down normally she says. We then went to turn it on and we will hear the chime but then it will get stuck on that first gray screen, nothing else comes up, no spinning no nothing. Hard drive is not making any different noise, I just don't know whats up.

It now shows me the gray screen, apple sign and spinning circle for about a minute before it's decided it's done and would like to turn itself off. I have tried resetting the PRAM and the SMC. I have tried restarting in safe mode. I tried to restart it off the AC adapter without the battery. I hear the chime, I see the apple, and the status circle, and then nothing!

I have tried resetting SMC
I have tried starting up in Safe Mode (it won't do that either)
I have gotten into disk utility to repair disk
I have tried resetting PRAM
nothing... we are on a network in a school district so my next step is to re-image it but wondering if there is something else I should try first
if not then how do I backup files that are needed before I re-image

I have a Macbook Air. I thought I had lost it, so I erased it from Find My Iphone. Then of course I found it, my computer was completely erased. When I started my computer I hear the chime, but then a blank grey screen (no apple). I have tried every start up command and reset. I have tried Command R, Option, with and without connecting an Toshiba hard drive that has my computer backed up. I have tried disconnecting everything more my computer. I'm not using an external keyboard.Â
Again, when I try command R, option, command n, D,T, the shift button, etc. nothing really happens the screen is still grey.
I switched out my HDD for an SSD and switched out my superdrive for the HDD. It was working fine for the past 6 months or so.Â
So, yesterday I plugged in my Macbook and started it up from hibernation. I then proceeded to launch chrome and as it tried to restore my last session (with like 5 or 6 YouTube tabs), it crashed. I tried closing it and re-opening it, but no cigar. I then thought to just open safari, but a no network detected warning came up. When trying to resolve that, an "unapproved caller" error came up.Â
I then tried to restore my computer from a TM backup, but was unable to due to it being unable to unmount the drive, then I tried just erasing the drive, nope.Â
I then decided to take the dang SSD out of the internal SATA connector and plugged it in through an external enclosure, that worked and I was able to restore my TM backup that way.Â
So bottom line, I can boot up from USB fine, but when I plug it into the internal SATA connector my MBP gets stuck at the apple logo. I've tried booting into safe mode, resetting the NVRAM and PVRAM. No luck. From what I've seen, it seems that I may have a bad SATA connector that needs to be replaced?Â
Whenever I start up my macbook it stayed on grey background with an apple logo and spinning thing. I press and hold the shift key once and it went to safe mode and did my diagnostic and found out that some file got corrupted so I thought maybe I'll just do another start up and everything will go back to normal. Then I restart it again but this time it wont past that grey back ground w/ apple logo w/ spinning thing again. I tried to do the safe mode again and it won't let me anymore. I went to apple site and i found a bunch of keyboard shortcuts, non of those help me. Any here have any idea what might happen to my MacBook. I'm in Kazahstan for work related trip and they don't use Mac here so there is no where I can buy another snowleaopard cd.
View 1 Replies View RelatedI have a 1.83 MBP, with 1.5 gigs of RAM (stock 512 + additional crucial 1gb) 80 gig HD. Pretty standard.My issue is that once in a while when I restart my machine, bootup is really slow and then I get a weird screen glitch. Often I won't get a full re-boot but will get a half appearing dock and no desktop icons. Sometimes it will have lots of grainy lines across it. Sometimes I will get the beach ball for extended times and it will just freeze there. Basically I keep restarting it, and eventually it goes away and boots up normal.
The thing is I can't really replicate the problem. It just happens at random. Sometimes it happens after I have a system crash, and I need to restart, and sometimes it happens just after a system update restart.Like I said, it doesn't happen that often, but when it does it kind of freaks me out. I've had the logic board replaced in the past to eliminate the "whinning" (which, thankfully is now gone) and I wonder if this is another logic board problem. Other than that the computer has been great. And upon the complementary Applecare expiring pretty soon, I wonder if I should take it in for a repair or just not worry about it. It's kind of hard to take it in if I can't really show them the problem.
I have an iMac G5 that is clearly booting up--you can hear the skype connection sound in the background--but I'm stuck w/ a blue screen. Tried P-RAM and other keyboard methods, to no avail. Took off back cover, seems as though only 1 fan is working.
Was able to connect iMac to my laptop via target mode, so it's truly a screen connection problem.
So I was just there, using my computer, doing nothing out-of-the-ordinary. I decided to open up a program (Yahoo! Instant Messenger, I think it was) and the computer went nuts. I completely froze...nothing I tried worked. So I shut the computer down and tried rebooting it. It chimed and went to the white start-up screen with the apple...I let it sit for about ten minutes to let it restart. Still the white screen. I shut it down and tried it again. Same thing.
Is my computer dead? What might I be able to do to fix it? How much might it cost?
My imac wont turn on. It sounds the chime but has a clear screen with a picture of a folder with a ? in it.

My computer won't turn on. Earlier today while playin music it just paused itself. I minute later it resumed. Then tonight it just shut off instead of sleeping and now it won't start. All I can get if I'm lucky is the start up chime and a super quick flash of a white screen.

I did a pram reset but that did nothing (I heard the initial chime and the one after the reset....still the same problem.) I'm a bit worried because I don't hear the hard drive starting up.
Some more info... Intel Imac 17" (late 2006 model), 512 mb of RAM, running 10.4 (I think). I am not familiar troubleshooting macs but I am troubleshooting PCs.
My iMac starts up to a white screen and stays that way and won't start.

During an upgrade, power was interrupted and when rebooting, the chime sounded, but screen remained gray.

ok my macbook wont boot. i hit the power button, i hear the cd drive move, grey screen comes up with the apply logo and the little progress loading spinner thing, boot sound rings, then it goes to a dark blue screen for a second then it turns a lighter blue and the cursor is there and i can move it around, and then nothing happens it just sits there
i tried holding command/option/p/r till i heard the boot noise twice then let go and it stopped at the blue screen again. i didnt download anything new or change any permissions or system settings, just powered off last night and went to turn it on this morning and this happened
Desktop restart shows flickering black/white screen, then black. Could not restart.

I came back from work to wake up my iMac. It made the noise but the screen stayed black. I tried restarting by holding the power button- I can hear it start and the chime but still have a black screen. I tried resetting the pram, and unplugging the cord but I still get a black screen. I can hear the chime though; I'm not sure if that means anything. I just had the hard drive replaced in February so I hope it's not that. just wanted to clarify that when I restart, I get the chime but the screen stays black- I don't get to the grey screen. So I'm assuming right now that my display may be shot?
