Gray progress bar on boot twice now

I've experienced a gray bar on boot twice now. I upgraded to a 2011 MBP and transferred my 500 GB Toshiba SSD from last year's MBP into the new model, into the SuperDrive slot using a MCE OptiBay (I put the existing SSD into the OptiBay since the SuperDrive's SATA channel is 3Gbps and the Vertex III I have on order is 6Gbps and will use the system's primary SATA channel). The drive has worked flawlessly for a year, and Disk Utility reports no errors, but Googling the issue indicates that the gray progress bar appears when fschk is checking the drive. I've noticed that my wallpaper has been slow to appear on both occasions, defaulting to the OS X default for a few moments after I log in.
I'm concerned that my drive is going bad, but cannot find any indication that this is the case beyond the intermittent gray progress bar on boot. At least one time after boot the progress bar occurred after a Software Update (Security and Safari). My system's logs also give me no indication what the problem might me. Here is one boot log that resulted in a gray progress bar - https://gist.github.com/922265.
I'd appreciate any help on the matter. Thanks!

I would expect either issue to produce a slow boot either time if either package were the problem. Both packages have been installed for a couple of yours without issue. Also, both apps produce these errors on normal boots as well. I wonder if the errors have to do with the fact that the applications weren't installed on the OS, rather they were already present after I put the old HD in the new system and "upgraded" the OS in place using the system disc that came with the new laptop in order to have the Sandy Bridge drivers installed.
I was hoping you or someone might spot something slightly more definitive in the logs. The time gaps are definitely interesting to me. I think I'll see if I can turn on verbose logging and get any more telling information. Thanks for your help!

Lion 10.7 gray progress bar appears under Apple logo on startup. Slow to boot to login prompt or Finder

iMac Troubleshooting topics section shows this topic for SnowLeopard10.6 and suggests that there may be a hard disk problem. Recommendation was to startup iMac from the 10.6 install disk and use Disk Utility to attempt to repair the hard disk. Lion 10.7.2 was downloaded so there is no disk to attempt this repair with. Any suggestions or experience with the gray cloth screen in Lion and a progress bar under the Apple logo on boot up? It seems to take a lot longer to boot up now to get a login prompt or desktop than when it was fresh out of the box in July 2011 with Snow Leopard 10.6 Thanks for your help!

Hello
just an idea
first shut down your mac then , unplug your keyboard if is a wired one , or remove battery from your wirless keyboard then power up your mac , does the progress bar appear again ?
or more simple try an other keyboard if is possible , preferably a wired keyboard

OS X: Gray progress bar, then MacBook shuts down

Hi Apple Community,
Last year I bought my first Mac ever for University and have been quite happy with it so far.
A few days ago I closed my MacBook when its battery was at ~2%. Normally when battery is that low when closing the MacBook it usually goes into hibernation instead of sleep. When put it on power again about an hour later and opened it again it wouldn't start properly. When I try to boot it now, I see the apple logo with the rotating thingy and a progress bar which fills up in about 5 or 7 minutes. After the bar is filled up the MacBook shuts down and I have to do it all again. So the computer never starts.
I did some research on the subject but all of the solutions couldn't help me. Internet recovery doesn't work, because it doesn't allow me to connect to my university VPN (which is necessary to use in uni accomodation). I also don't have a Recovery CD.
When I start Disk Utility (Cmd + Alt + R + P or something) it won't work as well and just tell me that the Macintosh HD "could not be repaired after three tries" or similar.
HOWEVER: It can't be a hardware problem, because I'm running Windowss 7 via bootcamp (from where I'm writing right now) and everything seems to be alright on here.
My Mac:
MacBook Pro 13" (mid 2012) running on Mavericks.
I'd really appreciate anyone who could help me. I have all my important files synced to my dropbox, but I don't really like the idea of reinstalling OS X
Thanks in advance,
Luka

Guess that's really my only option, thanks. I thougt OS X were indestructible.

IMac SLOWLY Starts Up With Progress Bar

Just the other day my iMac has started doing something very annoying: It starts up with a white screen and a gray progress bar, and it takes a long time to start. It does this each time I start it now. I have not added any new hardware/software. Any ideas?

That usually only happens if you had to manually force shut it down. See http://support.apple.com/kb/ht3964 for details.

IMac won't boot up. Instead I get a progress bar.

I turned my iMac on today and noticed a gray progress bar under the apple logo as it was booting up. Once the bar finished filling up, my computer turned itself off. I've tried booting it up multiple times but it does the same thing. I've also tried holding Shift as it booted up but it never really did anything. The only reason I can type this out right now is because I can still boot into Windows thanks to Bootcamp.
I know there was a really quick power outage this morning so I'm not sure if that had anything to do with this.
Thanks!

I strongly suggest a trip to an Apple repair station, given you had a power outage.

Progress bar appearing at startup

Every time I startup my MacBook pro a grey progress bar appears and sometimes after that when it loads up my desktop folders don't appear and I can't access finder.

Mac boot issue; gray screen, spinning wheel, and progress bar

Recently I shut down my Mac only to find when I tried turning it back on it was very slow and unresponsive. I proceeded to shut down a couple more times and this resulted in a gray screen upon startup with a spinning wheel, apple logo, and a progress bar. The progress bar did not fill at all at first, and as I left my laptop for about 40 minutes, it still hadn't moved. I proceeded then to boot in recovery and tried to repair my disk. This resulted in another issue, and would not repair, so I decided to just erase my HD, since there was not anything important on it anyways. I really just wanted my laptop to turn on so I could start my paper. Well it wouldn't erase my hard disk and this led to me becoming very impatient and just quitting the process. On the next attempt to boot in recovery, the hard disk doesn't even show up. Only the recovery disk (previously there were two disks as options, as well as the wifi selection). I'm now using safari through the recovery option. I'd like to simply get my computer back. If i can't get anywhere on here, i'm just going to bring it to the apple store and return it, most likely, as i've had nothing but problems with this thing. I've had it since the middle of September, and I can't hardly believe i've already encountered such an issue. Any help is much appreciated. Thanks.

I'd make a trip to the Apple Store - your hard disk may be dying (the Recovery partition is very small) or there might be something corrupt in your system. They'll be able to evaluate it.

IMac starts, shuts down - gray screen w/ progress bar

I have a 2007 iMac and it is now shutting down every time I try and restart it. I see a gray screen with the apple logo, the spinning wheel and the progress bar upon every restart. The progress bar never finishes and it shuts down.
I have restarted with command-option-P-R - same result
I have restarted with command-S - same result
I have restarted with command-C - it kept spitting the disc out then it would shut down again
I have restarted with command-V and it said something about incorrect block counts. It also at the very end, just before shutting down again said "Disk Full Error" and "killing all processes done". I had to snap a picture with my phone to see what it actually said since it happened so fast. I knew the hard drive was almost full and was actually backing up to and external hard drive just before this issue began.
Is there anyway for me to force the computer to stay on long enough for me to remove some items and free up space? Like an override somehow?
Thanks so much in advance for the help!

Try restarting, when you hear the startup tone hold down the Option key. Then choose the Recovery Partition.

I have an iphone 4 and I have just upgraded to iOS 5. I have lost my progress bar and song repeat function, how can I get them back?

I have an iphone 4 and I have just upgraded to iOS 5. Unlike some people, I have not really had any problems but I am really annoyed with the new music feature. I have lost my progress bar abd song repeat function. Does anyone know how I can get them back?

Glad to hear it all works for you.
For future reference, if your iPhone misbehaves, always try a Reset. It's painless and often solves the problem.
Press and hold both the Sleep/Wake button and the Home button for at least ten seconds, until the Apple logo appears (ignore the Slide to Power Off option that shows up first).
Enjoy.

Progress bar at gray screen, then shuts down

Hello. I work in a private high school and a staff member handed me his MacBook Pro (13-inch, Mid 2012). He says that in the process of doing updates (he was non-specific about what it was updating), he shut the display and now it won't ever fully boot. This is what I observe: Connect power adapter to it, confirm laptop is fully charged, press power button. At the initial gray screen, the black apple shows and a black progress bar appears at the bottom (not the spinning gear), which gets part-way through and then promptly shuts down. Sometimes it gets through the progress bar and the spinning gear for a few seconds before it shuts down.
I've booted to the Recovery Partition and run Disk Utility on the physical volume... and the physical hard drive appears to be fine. Since I've left my external USB drive with Maverick's installed, I'll have to wait until tomorrow to attempt cloning the drive and/or pulling off a copy of the user accounts. Once I get a copy complete, I may try a full restore, but...
In the meanwhile, does anyone have any ideas as to what might be causing this problem?
I have seen several other related threads in these forums, but most suggest that it may be a physically damaged hard drive, which isn't appearing to be the case here (at least not yet). Another post suggested that it may be a video issue, but it boots fine into the Recovery Partition. Do you think it's possible that one of the updates was a firmware update that never got properly installed due to his shutting the display-lid? Another post suggested trying to boot in Safe Mode, but that also fails similarly.
I'm open to ideas and suggestions.

Here is the Apple support article regarding the symptom you describe:

I trust that the data on the MBP is backed up.
Have you tried a safe boot?
