Disk Utility in OS X gave me a Invalid key length after checking Catalog file, so I restarted to OS X Install DVD. It did the same thing on the OS X Install DVD. I went to Startup Disk, changed it back to the Mac OS X on Macintosh HD option - so I could go in and back my stuff up. It just goes to apple logo, does the spin thing at the bottom, and goes black. I can't even boot from DVD anymore.

Do any of you have a sensor-type looking thing on your iMac's? It's on the black strip around the edges just above the black Apple Logo.See my picture for what it looks like (you'll have to look closely to see it):I'm interested to see your responses of what it could be/is. I've only had the machine for going on for 3 days now so I'm new to the whole iMac thing.
View 4 Replies View RelatedThe little progress spinner thing below the apple just spins and spins. The computer said that several apps stopped responding and had to quit after falling asleep watching a movie in VLC, which had error logs that had frozen on the screen as well saying, "Computer too slow?" from dropped frames apparently. Not normal. Also, yesterday, when waking it up from the display shutting down, the whole screen was gray and smeared looking. There was nothing recognizable at all on the screen, and I hit the power button quickly for it to sleep, and back again and it worked fine for the rest of the day. Its a 1.66 Core Duo Mac mini w/ 2gb of RAM.

View 1 Replies View RelatedCame home from work the other day and my iMac (20" iMac from '07 / Snow Leopard) was frozen, did a hard restart and it booted up fine without much of a problem. Everything was running very sluggish so I began to verify the disc through utilities at which point it froze again, now whenever I restart I get stuck at a white screen with apple logo and something spinning underneath it. The longest I've let it sit at that screen is about an hour or so, it gets extremely hot though so I'm hesitant to leave it any longer.
I've tried a few suggestions already, safe mode with no luck, disc target onto my macbook with no luck and I've tried "/sbin/fsck/ -fy" at the command prompt which returns something along the lines of Harddrive can not be repaired. The most important thing to me right now is being able to access some of the files on there if it is not a total loss. I've back up about 2 months ago, so it wont be a total loss, but like I said, would prefer to salvage anything I can.
Today i discover that when my macbook pro screen is black and i place light behind the screen, i can see through apple logo. Is it normal ?
Info:
MacBook Pro, OS X Mavericks (10.9.4), Iphone 5s
Macbook: A1181 Core 2 Duo 2.0ghz 1GB RAM
DVD disk: Leopard 10.5 Retail install
Hard drive: dead (spins with clicks).
With regular startup I get the flashing question mark and can hear the failed hard drive click and spin. After getting the DVD to boot in the drive (it doesn't suck it in right away), I get an apple logo and pinwheel like I should, but after about 30 seconds it goes to a black (blank) screen and the DVD spins down, but not all the way. The computer is still on, but nothing happens.
Oddities:
<>If I start it with an iMac 10.4 DVD I can boot to the install screen just fine, but can't install because it's an iMac DVD. I can erase and partition the drive fine (not the dead one, another one I have).
<>Safe mode boot does the same thing, but takes 20 times as long to boot
<>Retail OSX 10.4 DVD does not boot at all, but that one might be for PowerPC computers. I get the flashing question mark folder.
I purchased a new late 2013 27 inch iMac 3.4Ghz i5. The only thing I did after pulling it out of the box was restore Time Machine from my previous iMac. On startup the machine boots as expected, but gets interrupted by the screen turning a dark blue, and the apple logo turning bright red, for about a second or so, then boots as normal, and opens Mavericks. I've spoken to Applecare - they suggested I re-install Mavericks, which I did. The problem is still there. I've done a hardware diagnostics test - no problems. Though I wonder if it could be a faulty graphics card? As far as I'm aware there are no other issues with the iMac. The machine is under warranty but would love to solve this if possible.

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?
I was trying to install Windows XP Pro, but for some reason the it wasn't showing another HDD to install Windows on. So I quit the install, and restarted my computer. Now all that happens is the normal grey screen appears (with no Apple logo), then it goes to a black screen and has the blinking cursor (Kinda like DOS).

My screen is black but my laptop is not off.. and its not that only the screen is black, my mac on sleep (i think)...When I turn my mac on, it does turn on.. The starting screen comes out.. but the moment the desktop opens, the screen goes black. And if I try to wake my mac up by pressing any key, the mouse shows for like three seconds(on the black screen, not my desktop). So that means that my mac is not totally off, it's just that the screen is black. But once in a while, when I press any button, my desktop shows for five seconds and the screen turns black again. I had yesterday was that the finder was keep restarting. I was still able to go on all the apps except that I could not open any files on my desktop.
View 1 Replies View Relatedmy MBP is really screwing up these days. Basically the best way I can describe it is that randomly once in awhile (no matter what I'm doing, usually surfing the net) the screen flickers a few times, then most of it turns black (except usually for a small part on top that stays on whatever it was displaying before). The section between the part that stayed the same and the bottom is sort of "multicolored".
The computer does not respond to anything except holding the power button down for 5 seconds until it shuts off. If I try to adjust brightness or sound level, nothing happens. Anyway, I took it in to apple and they claimed it was the motherboard, so they replaced it. But today I had the problem again! What else could it even be? Any chance its the RAM/screen/hard drive?

I'm using an external Monitor (Compaq W185q) and everything's ok until I open certain webs, this websites have banners on both sides mostly, so I think that's important to tell. After couple seconds on those sites, the monitor starts flickering and then it turns black, completely. To make it work, I launch Mission Control and it starts working again, I drag the safari window back to my MBA's monitor, and problem solved.

Anyone else noticing their new macbook air freezing randomly and the screen just turns completely black? The back light is still on but nothing is on the screen.
None of the buttons work, can't force quit anything, i have to hold power button to turn it off then back on.
It has happened to me twice already, first time when i was installing the adobe suite, second time is when I was working on a school assignment with a simulation app (not cpu or memory intensive AT ALL).
It was just an accidental liquid spill, but however my macbook pro has been acting up before all this mishap with the graphics. I thought is was just nothing so I didn't care to bring it to an apple store but when I had to bring it and check it out using the Nvidia video test it presumed a failed video card. The genuius said it will take 2 weeks to be fix until several days later I recieved a call saying it can not be fix due to a foreseen amount of liquid damage. I've spilt other liquid items but wiped it off the keyboard quickly and it still worked. I'm using my MBP right now with an external monitor, it still works fine but with the issue of the screen being pitch black.

When I was in the bed las night, the apple logo was so darn bright in the bedroom it woke the wife up once! Can I turn that sucker down a little for night time use, or should I position the pillow to cover the back up?

Son's Eagle Project. Set up GroPro to snap a pic every 10 seconds. Now have 3,000+ photos in Aperture, in slideshow with most running at 1/10th second. Added text annotations.
In Aperture - plays perfectly.
Once exported - 75% through the video, screen goes black EXCEPT that the annotations I've made are retained - so occasionally a timestamp or comment appears on an otherwise black screen.
I've tried multiple export formats, no difference. Am now resorting to inserting timestamp slides between pictures to see if somehow there is a corrupted image that is causing the video export to fail.
Have replicated problem after a reboot with nothing of substance other Aperture running.
