MacBook Air :: Will Not Bootup To Login Screen When Powered Up
Jun 3, 2014
will not boot up to log in screen when powered up, all I get is a grey screen with apple logo in middle and spinning timer
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
Info:
MacBook Air, OS X Mountain Lion (10.8.5)

My MacBook has suddenly gone dark. It charges fine and the battery lights show there's charge. The screen is very dark when powered up? When I turn the brightness down fully, then go to turn it up the screen lights up for a second then goes again?

When I power on, my macbook pro does nothing (blank screen) after the sound.
System:
-Macbook Pro Retina 13' (Mid 2014) 256GB SSD, i5, 8Gig RAM
-Yosemite (10.10)
I tried to install Windows 8.1 using bootcamp assistant on Yosemite. After installing Windows 8.1, it asked me to restart.
When I restarted it stuck on blank screen. I've heard the startup noise but nothing happened. I tried many startup key combinations such as; Command(Alt), cmd+R,cmd+V,T, but the screen is always blank. Although the screen light is, on the screen is totally blank.
I did resetting SMC, and also I did cmd+alt+P+R (I've heard 4 times startup sound) but the screen is always blank. Nothing happens. I can only shut down by pressing the power button for 4 seconds. As a result when I power on, I hear the sound but nothing happens. Nothing on the screen.
What I did before was: The system is a brand new mac. I bought it 1 week ago.
1- I tried to install windows 8.1 using bootcamp. But failed. Because windows installer gave me an error that windows can not be installed on GPT partition.(I have also MacBook Air and MacMini with bootcamp Windows 8.1 working fine.)
2- Then I rebooted using Alt key then booted to MacOSX and deleted the windows part and many combinations. But failed. The error was always the same GPT error.
3- I reinstalled Yosemite tried all the steps but failed with the same error (GPT error)
4- We had another same macbook pro. And we could install windows 8.1 easily.
5- I compared the two machines in windows setup. The problematic mac had first partition labelled EFI.
6- Then after a few hours. I tried to install again. And saw that the EFI label was gone!. But I don't know how this is happened.
7- I was happy and started to install windows. After installing the system gone!!.

So my computer froze while I was waking it up from it's nap, so I restarted it by holding down the power button. 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 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.
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.
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.
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.
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?

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.

I 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 recently have been having start up problems, when I would hit the power button I would sometimes hear a healthy startup and everything would boot up and then I just get a black screen and you can still tell it has power. I would start and restart untill it would boot. Now the only way the machine will start is if I unplug the moniter cord and plug it back in then it will start.

Hi! Im new to the forums but i really need help with something and i was hoping someone here could help me out. So I just installed Tech Tool Deluxe onto my macbook and then shut it down later. I went back to use it again and when i turned it on a login screen appeared asking me to put in my password. I did that and the screen turned blue (looking like it was loading) and then went back to the login screen. Every time i put in my password it just takes me back to the login screen. I have had my mac for a while and i dont want my hardrive to get wiped out so what do i do? Thank you for looking

On my mid 2007 Aluminum 24" Intel Imac shows nothing but a white screen when powered on even though according to the diagnostic LED lights which are all powered on and green the logic board, video card, and everything else are speaking back and forth to each other perfectly fine. Does this mean the LED screen is bad or (from what I've read) is it a possibility the hard drive is bad? I know the optical drive is bad and will not spit out any discs. The #1 reinstallation disc for the OS is stuck inside right now. Before I order a new screen, inverter, and optical drive I figured I should ask in here to see if it is just bad hard drive or something else. Wouldn't the LED diagnostic lights tell me if the hard drive was bad?

I tried uploading pictures with my s.card and then I plugged in my back up storage disk to transfer pictures and then my computer stopped working as if it was overloaded or something.... I tried forcing quit but that didn't help any. So I just shut it down in hopes that when it restarted it would work but now when it restarts the login screen comes up and after I type my password it just stays on snow leopard default screen(purple sky) and stays there.

I've been using my Intel Mac-Mini without a hitch for three years now. Previously it had been plugged into a Samsung 32" LCD TV, but I've just swapped it over for a 1080p Panasonic 37".
Now when I turn on the mac it takes a long time to boot up and then eventually settles on a blue screen. The mouse pointer is visible but nothing else. I've tried using a dvi to vga adaptor and an HDMI to vga cable and the same thing happens.I tried a 15" Samsung monitor and the same thing happens.
If I boot in 'safe' mode it allows me to type in my password but when I try to log in it fades to blue and then returns to the log in page.

My Dad is having issue with his MacBook Pro. So today he shut the MacBook down, but when he switched it on again it booted fine, right through the chime and Apple logo, but when it got to the login screen it switched off. The power adaptor was connected. He has been having problems with the battery, with it not holding a charge.

My Macbook(bought last year) just crashed and I had to turn it off by holding down the power button. Now after I turn it back on, it takes a really long time to load and when I get to the login, I can't type my password in the box. I can still move the pointer around, but can't click anything with the trackpad. I've also tried an external usb keyboard but that also doesn't work.

Bought a refurb from Apple and they don't send the install disk. Now can't get past the login screen. Thought I left the password blank but it won't let me get past the start up screen. Tried the install disk from my 15 inch mbp by holding C and starting up. but it only tells me I need to restart.

i recently had some repairs done to my mac and since i got it back, it goes back to the login screen after only 5 minutes of inactivity, i have changed the display and computer sleep options, and tried changing the user login options, all to no avail.
This problem is extremely frustrating, especially when i just want to play music while i clean the house or something.

I have a the 1st generation Macbook Pro. It has been working fine up until last night it would not load the login screen. It would show a checkerboard screen at the login view and other times it would show the login screen all streched out wit the checkerboard on top of it. I have tried fsck-ing, removing the PRAM. I then booted in Safe Mode (which worked fine) and attempted to repair disk permissions through Disk Utility and it seemed like there were a lot of errors in the Java part. I attempted to boot up the Mac OS Install disk (Snow Leopard) but the same checkerboard screen from the login popped up.
(This is the image of the login screen when attempting to boot up normally.)

I Have a 15" MacBook Pro with Retina display. I tried to move files off the hard drive when I got a message warning me that the drive was almost full. I shut down, connected an external hard drive to move some files, but on reboot, the screen went blank (white) after typing in my login details.

I have just replaced the display panel in my MacBook Pro (A1260) and now it is behaving oddly at startup. The backlight lights up normally until the boot process gets to the Login screen, at that point the LEDs shut off. I can see the images on the display, (the LCD seems OK,) the only issue is that the LEDs are turning off.
Here's what I've tried:
1) If I boot in Target mode, the screen stays lit. (As expected.)
2) If I reset PRAM, the lamp behaves normally, staying on through that session. If I restart, the lamp-off- condition returns.
3) I have reset the SMC per instructions here, [URL]. No change, LEDs shut off.

I've been experiencing a problem with my 2007 MacBook Pro. At seemingly random intervals the computer freezes, the screen goes blue, and restarts at the login screen. It does NOT fully restart the computer, which is why I'm having difficulty finding a solution to this problem since most info online seems to deal with that issue.
I took it to the Genius Bar -- they reset the cache and system permissions -- but the problem remains unsolved. There's no new hardware of software I can think of..MacBook Pro Intel Core 2 Duo 2.2 Ghz running Mac OSX 10.6.8. Please let me know if I can provide more info.

I just received a 13inch MBP i7. I setup a user account during the installation. Everything worked good until I logged out. Now, when in the login screen after a reboot, the keyboard does not respond (can't enter my password).
I know it is not a hardware issue as I can type fine when logging into my Guest Account.
Here is what I tried to fix this:
- reset NVRAM
- Disk Repair
- Repair Permissions
