MacBook Pro :: Gray Progress Bar Starts And Then Computer Shuts Off

Aug 27, 2014

My MacBook Pro will not start. It chimes and the gray progress bar starts and then the computer shuts off. I am able to start it holding the Command +R keys and access Disk Utility. That is where it says my S.M.A.R.T. drive is "failing". I have a backup from Time Machine from a week ago. I am concerned the computer is going to die. What should I do and is my computer going to die?.

MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9.4), 8GB RAM

MacBook Pro :: Computer Starts With Gray Apple Screen Then Turns White

Sep 29, 2010

I am trying to fix a friends macbook pro. When I turn it on the screen shows the apple and the spiral underneath it spinning like it should then when it stalls for .2 seconds it goes to a white screen then there is vertical purple lines in groups across the screen. So the screen is white/purple. Then it fades to just white and I cant do anything.

I hooked up my monitor with a DVI cable to see if it was the motherboard that was possibly bad but the monitor works just fine with the cable. I can use the computer with the laptop keyboard/mouse and it works just fine. The laptop screen just stays blank the whole time. I uploaded a vid to utube for it. If anybody has any ideas for me please help. I dont know if this is a monitor problem or the inverter or the motherboard, possibly some other piece of hardware?

MacBook Pro :: Does Not Boot Even In Safe Mode - Shuts Down When Progress Bar Reach To 25%

Aug 21, 2014

I'm facing an issue with my MacBook Pro Mid 2010. It hangs on startup and only shows a white screen with the Apple logo and an activity indicator. 

I already tried:

- Replacing the HDD with a new SSD with Mavericks installed (if I put this SSD into another MacBook everything works fine)
- when trying to boot in Safe Mode it reaches about 25% in the progress bar and then shuts down
- same when I boot in Single User Mode
- when I boot in verbose mode I'm getting this output 

jnl: disk0s2: open: journal checksum is bad (0xbff2db8 != 0xbff35a0)
jnl: disk0s2: replay_journal: from: 10668032 to: 12240896 (joffset 0x747000)
jnl: disk0s2: replay_journal: bogus block number 0x907a985480c1ad24
jnl: disk0s2: no known good txn start offset! aborting journal replay.

[Code] .....

Then the MacBook shuts down.

OS X V10.7 Lion :: MacBook Suddenly Won't Progress Past Gray Screen

Apr 28, 2012

My macbook suddenly won't progress past the grey screen and the spinning gear. I have tried the procedures listed in one of the support documents, although I note they don't include OSX10.7 which I am running. I got to the part where it says try your system disk, problem is, I purchased through App store.I'm guessing at this stage I should have created an emergency boot disk.

OS X :: Software Update Will Open And Progress Bar Starts At About 10% And Never Moves?

Mar 2, 2009

My software update will open and the progress bar starts at about 10% and never moves. I read other posts saying it was downloading update and to give it time... I have a decently fast connection and left it running for almost 24 hours and it never budged. Does anyone have any ideas on what is wrong or how to fix it. If no one has any ideas, I will take it to Genius Bar, but thats a long drive for me, so I would prefer to figure it out on here!

When sharing "Apple 1080p" the progress bar jumps right to 9% then stays there no matter how long you leave it.I have restarted, shut down, cleared memory, and tried three different destinations (USB, Ex HD, iMac HD)

Mac Pro :: Gray Progress Bar During Startup

Apr 6, 2012

I called in and asked about a slowly running computer and Applecare suggested holding Option+Control+Shift+Power Button for 5-10 seconds and then releasing and then hold the shift button while powering on to go into safe mode. I did this on my macbook pro as he told me and decided to go ahead and do it on my IMac and mac pro as well. It worked on the MBP and IMac but on the Mac Pro the computer came on when I held the first key combo and is taking a really long time (hours) to start up. I need the computer to work, for work. I tried just restarting the computer, unplugging it, etc but each time it has the gray progress bar and takes a really long time.Of course I downloaded and updated to the newest operating system through mac app store so I don't have a start up disc...

Mac Pro 8 Core / 16GB DDR3 / 3 x 2.0TB + 500GB HDD / 2 x NVIDIA GT 120, Mac OS X (10.7.1), 2 x 23' Samsung Syncmaster 2494 / Bella Pro 3.0 / Apple Magic Mo

Macbook Pro Shuts Off After Few Seconds Of Gray Screen

May 15, 2012

I came home to discover my power cord had died and my laptop turned off due to no power. I used a friend's power cord to turn it on later that night and send some emails. I bought a new power cord the next day, plugged in, and turned the laptop on. It stayed on the gray screen with a spinning wheel beneath the apple logo for a while. I restarted it and it turned off after a few seconds of the gray screen. An empty bar flashes twice horizontally at the bottom before the spinning bar begins.I tried booting in safe mode, but it would just stay on the gray screen. I tried doing shift+command+v and received a message about keys out of order and disk error full, can't repair. I was able to boot from the install disc, and when I click "Repair Disc" I get the same erros. Not sure what to do now?

MacBook :: Won't Boot Past Gray Screen With Apple Logo And Then Shuts Off

May 29, 2012

This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart. Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. I already tried the Command-Option-P-R keys trick like five times.

OS X V10.7 Lion :: IMac Starts To Boot And Then Shuts Off?

Feb 4, 2012

I have a 2009 iMac with SSD drive and 2TB drive.For the last 6 months, I'd get kernel errors every now and again, and I would reboot and things would be fine. A few days ago, the computer totally froze, and when I turned it on, it would shut right off. I tried booting to recovery partition, nothing worked. I took it to the apple store yesterday and they hooked it up to an external drive and then did a diagnostic test and the genius said it needed a fresh install of lion, that something was corrupting it. So we did that (for some reason though, it took about 4 tries for him to get it), and then I took the computer home and ran time machine.

Every thing worked as it should for about 12 hours, I did reboot a few times in that time. Anyways, now, it's back to where it was where I turn it on, there's a status bar on the bottom that fills about halfway and then the iMac shuts down. The apple genius said that a corrupt program/application might be causing that. I find this hard to believe ... I can understand a corrupt program crashing or not starting, but is it possible for that to not allow the computer to even turn on? The other thing is that when the computer crashed a few days ago, I hadn't installed anything new/etc .... ???

OS X :: Unable To Run System With Battery / Starts Up But Immediately Shuts Down

Feb 16, 2008

Just wondering if anyone has ever encountered this or if any experts out there know of the issue.

I have a spare White Macbook (late 2008: Core 2 Duo 2.1GHz, 1GB, 120GB) that I'd like to set up for my brother to use to introduce him to the wonderful world of Macs. The problem it is having is that when I have a battery connected to it (I tried 2 different ones included a known-good one that is brand-new just purchased from Apple) it powers on and gives me the chime, but then immediately shuts off unexpectedly giving that little "whine" sound like if it just lost power all of a sudden. However, when i take out the battery, and just plug it into the Magsafe AC charger it works fine. Also when just trying to run on battery it does not turn on at all. Here's some cliffs:

1) Macbook with just battery does not turn on
2) Macbook with battery + Magsafe AC charger connects powers on, gives the chime, but then immediately shuts off making the "whine" sound as if the power was suddenly cut off
3) Macbook with no battery connected and just the Magsafe AC charger connected works fine.

Do you guys think this is either:

A) battery connector issue (the little piece with the metal wires that the battery connects to. ~$50 part)
B) Logic Board issue

I already tried resetting the PRAM and SMU to no avail.

Intel Mac :: Beachball Starts Up But Then Quickly Shuts Back Down?

Jun 27, 2012

I can turn on my mac, the beach ball starts spinning and stays spinning for awhile, finally starts up but then quickly shuts back down? I have never encountered this type of problem with my desktop before!  I have checked all the power supplies and reset the powercord,  I unplugged the computer and tried to reboot it to no avail.  Does anyone know how to do the type of reboot where you hold down the power button and two keys (?) wait for the 2nd chime then let go of the keys?  I believe that is how it's done.

OS X Mountain Lion :: Mac Pro Gray Bar And Then Shuts Down

Jun 24, 2014

I'm not sure if my Mac Pro is starting up with the grey progress bar because of updates. I don't remember updating tho. When the progress bar finishes the computer shuts down. I've been turning it on for four times now and I still get the same result. I'm really anxious because I don't have backup and I need to finish my thesis in two weeks.

Macbook pro intel core duo. My macbook is turned off, when I press the power button the light goes on and the computer starts making sounds of turning on for about half a second and than shuts off. I tried removing the battery and putting it again, I tried to hold the power button (the light flickers at one point and eventually shuts off as well after 2 seconds), and tried turning it on with the adapter plugged in and unplugged.

Then I unplugged the printer and plugged in the power chord. it started, but it's very slow, and I keep getting the pinwheel.

MacBook Pro :: GPU Panic Error - Computer Frequently Shuts Down

Jul 1, 2014

Recently my MBP retina late 2012 started crashing with the screen going all black leaving the keyboard lights on. I had to force it to restart. After a couple of attempts I could finally access the computer for about 10 min before it crashed again, during which i could see the logs. As of know it has been on for 1 hour without any issues but when I run some more hardware-intense programs it crashes. Since i bought the computer from a private person without insurance im not entitled to the 3 year warranty. 

Im getting these errors:
