Gray Boot Screen with progress bar & SMC Issues

Hi All,
Over the last few days I've experienced the grey boot screen with progress bar three separate times after the finder froze and I was forced to manually reboot my imac. Previously I have only seen this during a Firmware update.
I am also concerned about the Finder freezing. It has been happening when I've been trying to access any of my external hard drives at random intervals (connected via usb, and f800). I am concered that my SMC controller might be failing as these drives are testing fine on other computers and in drive test programs. Also, the f800 drives have been self unmounting.
I had my internal drive replaced by apple a few weeks ago, could they have somehow damaged the smc controller unintentially? Or is this simply a Snow Leopard hiccup? (I'm running 10.6.2). I'm really starting to get annoyed with having to hard reboot or constantly reset my SMC. Any ideas before I take it in to a store?
Thanks!

I have found other users have this same problem when using windows. My setup worked fine until I did a windows update. Now apple partition is inaccessible. Guess the windows update whacked the apple partition. Apple should have a workaround. Bad Windows!

Splash screen with progress bar and multiple jar files to load

Hello,
I have been looking to the new features in java 6 for splash screens. I haven't implemented this never before and i was wondering how i could do the following with java 1.5 or 6:
I would like to see a splash screen with a progress bar that "grows" when every jar file has been read.
At this time i call my application like this from a shell script:
exec "$JAVA_BIN" -Djava.library.path=$LIBRARIES_J3D -classpath xxxx.jar yyyy.jar zzzz.jar ...
where xxx.jar, yyy.jar and zzz.jar are very heavy jars.
So i would like to see in the progress bar 33% 66% and 100% when they are loaded.
I do not know if this is the right forum to ask for this. If no, please point me which would be the ideal one.
Any help will be very useful. Thanks to all!

Mac frozen at boot-up screen with progress bar

I was running windows 7 on boot-camp and when i shut off my computer by pressing and holding the power button and then turning it on again and letting it boot to mac os x by itself. It turned on started to boot but a progress bar popped up under the cog wheel and it was taking a while so i shut it off by holding the power button and tried to turn it on again. I turned it on the same thing happened except this time the progress bar disappeared when it was less than 1/10 loaded and the cogwheel kept on turning for the next 15 minutes. Now every time it turns on it does that and won't boot up mac os x. Iv tried to hold the shift key while it boots and tried to boot it up by holding the options key (didn't work...), oh and windows 7 still works in boot-camp. Can i get some help please?

I have asked that your post be moved to the intel forum, you do not have a G5.

Grey screen boot up with progress bar every time

The machine been behaving oddly for the past two days, every time I boot up, I get the grey screen with the apple, circle and progress bar. The machine will load but it takes 15 mins+ every single time. Any idea if its hardware or software related?

I don't think it's the shift key, when the laptop is fully booted, everything works great. It's just the boot-up part that it taking 15 mins, like I don't think so, when the laptop is fully booted, everything works great. It's just the boot-up part that it taking 15 mins. I believe leroydouglas is right about it booting into safe boot mode every time. The HD spins really fast at that during the boot up and I'm in the midst of backing up my essential data.
I will try to repair with Disk Utility next. Suggestions are welcomed! Thanks!

MacBook Pro frozen on startup screen with progress bar and then it turns off

Hello, I have a MacBook Pro 15" of early 2012 with a i5 Intel, 4GB of RAM and a 500 GB HD.
I was installing the new suit of Adobe, when suddenly my Mac got frozen, vertical coloured lines appeared and the image on screen went distorted. I had to reboot the Mac by holding the power button until the screen turned off and when I turned it on, the lines appeared again and it itself automatically rebooted. Then the screen (now with no vertical lines) got frozen on the startup grey screen with the apple logo and the spinning wheel for hours with no response.
I tried to follow the steps of the official mac forums like verifying the HD with CMD+R and then Disk Utility, it says everything's fine; the same happens with CMD+S, no errors. I reinstalled Mavericks with the same CMD+R. I already reset the PRAM, SMC and performed a Safe Boot staring up in Single user mode and Verbose Mode and nothing, the same startup screen. I made too thins thing of holding shift until the progress bar appeared. Three days later (Today) I repeated the steps again and finally the verbose mode. Now, when I turn it on, the startup screen appears again (Apple Log and spinning wheel) with a progress bar. When it completes, the Mac turn itself off.
if you can help me, please. I don't know what else to do. The last thing is technical service.

Help: grey screen with progress bar at startup, no success repairing in disk utility

I got my MacBook pro in December 2011 and never had an issue with it until this same thing happened in February 2013.
Basically, what happens is the computer starts to run really slowly, so I forced shut down. When I tried to power it back on, I can't get past a grey screen with a progrerss bar that doesn't move for about a minute, and then the computer just shuts back off. I tried to some research to figure out how to fix it myself (grateful for my ipad as a back-up computer) but I'm afraid I'm stuck now.
I tried running disk utility from recovery mode to verify and repair disk, but I only got errors saying "disk utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files." When this all happened in February, I bought an external HD for the Genius Bar dude to back up my files and do whatever he did over the course of 3 days to repair my system. Apparently it was only a temporary fix. However, like an idiot, even with all of that hassle, I never set up Time Machine (I know, I know, spare the lecture. I definitely will this time around). I'm really not too concerned about the data on my drive because most of my important stuff is on USB storage/my work computer. However, there are pictures on there that I'd really like to salvage.
So, before I do the walk of shame back into the Apple Store, can anyone offer a guide for saving my stuff and repairing my hard drive myself? And, if I have a worst case scenario on my hands, how expensive will it be to buy/install a new hard drive?...or just how to prevent it from happening in the future? Thanks in advance.

The fsck drive check at boot is failing to fix your drive, gets stuck and the hardware shuts down the machine if a OS isn't loaded in time.
"disk utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files."
Yep, it will either have to be replaced or zero erased and completely reformatted and everything installed again.

I never set up Time Machine
However, there are pictures on there that I'd really like to salvage.
That's ok, the TimeMachine likely would have backed up the corrupted data and fail to properly restore anyway.
Since you can boot from RecoveryHD, that means you can install OS X on a blank external powered drive and boot from it and access the internal drive for your files. Or as a last restort install Data Rescue ($100) and that can read even deleted files off the drive bypassing the file system etc.

Booting up with progress bar

I was running Spotify earlier today with a completely dim screen to save battery. The battery died and I just plugged it in and tried to wake it up. I saw the screen for a few seconds and then it went black. Trying to brighten the screen did nothing and neither did pressing the power button. So I decided to hold down the power button and restart. When I did, I got the apple logo with a spinning wheel and a progress bar under it. It's been sitting like that for over an hour with the progress bar not filling at all. What should I do? Should I let it sit like that and see if it fills eventually? Or try to reset the pram?

Try restarting your MacBook Pro in recovery mode (holding down the command + R keys while restarting) then run disk utility on your hard drive to repair it. http://support.apple.com/kb/HT1782

Won't wakeup w/o power button, then grey dimmed screen with progress bar

Hello to all,
My PB Alu works flawlessly but for one problem. I can't wake it up as I usually do by simply touching the keyboard or opening it up.
I now have to push the power button for a long time, then it kind of restarts but instead of getting the usual startup, I get the last screen I had when the computer got in sleep mode, totally dimmed and in black and white (slightly grey) with a progress bar at the bottom. When finished, the computer returns to the screen I had when I put it to sleep.
A long slow procedure and specially annoying when an external screen is connected.
What can this be?
Thanks for the help.

Hello:
I would try restoring as an approach to eliminating some software glitch. However, you might also have a hardware problem (not good news).

My Macbook will not load past grey screen with progress bar?

When I start up my computer the grey screen with the Apple and spinning wheel appear, then underneath a progress bar. once the progress bar is full it shuts down? Help!

Welcome to the Apple Support Communities
That bar appears when OS X checks your hard drive, and it's not a good sign that your Mac turns off, because the hard drive is damaged.
Unfortunately, the only thing you can do is to take the Mac to an Apple Store or AASP to get the hard drive repaired. If you didn't make a backup, try DiskWarrior to recover data, and buy an external disk to make backups. All hard drives fail, but we don't know when they are going to fail

IMac 24 won't start up, grey screen with progress bar, then shuts off

My computer froze all my applications yesterday. When I went to restart it a grey screen came up with the progress bar at the bottom. It would advance about 1/3 and then the progress bar would start over. It would advance about 1/3 again then the computer shuts off. It does the same thing trying to start it up in safe mode. I started it with my snow leopard disk and it will allow me to restore the computer with time machine (which we have), but I wasn't sure if I should try something else before that. Any help would be greatly appreciated. Many thanks.

Stuck on booting screen (loading progress bar)

My Mac stuck on the booting screen (the grey page) then shuts down, I've opened the recovery mode by holding the command+R then opened disk utilities -> verifyied my desk -> found errors -> repaired my desk -> Got red message "Disk utility can't repair this disk. Back up as many of your files as possible!" then i decided to create an image to store it on my external hardrive i got this message "Unable to create image input/output error"
What i have to do ? I need to back up my files and get my MAC running well !

You have already tried repair, and it did not fix enough to get your Mac working again.
Now buy two hard drives and enclosures.
One is a Large Backup drive. USB-2 enclosure will suffice, but the bigger the better. It does not have to be a notebook (2.5-in) form factor.
The Other is a candidate for a replacement for your internal drive -- but do not move it just yet.
While it is still in the external enclosure, Install Mac OS X on it and boot from it. Now you can get some work done if needed, and can use the full power of Mac OS X and additional Utilities to attempt to repair your drive and salvage your files. Mac OS X is about 400,000 of those files, so if they cannot be saved, it does not matter.
Once you have salvaged what you can and are confident that the new Boot drive works, you can swap it inside your MacBook and get portability back.

MBP stuck at gray boot screen with apple logo, loading wheel, and loading bar

Today i was using my mac book pro and it was working just fine, and i shut it off and when i tried to use it later I get stuck at this screen. I have never seen this loading bar and it doesnt seem to do any thing because it only goes as far as it is in the picture then it dissapears leaving me stuck at the apple logo and the loading wheel.
Sadly i cant get my warranty information since i cant get past boot up, and the serial number in the battery area is to small to read (the letters or numbers are literaly blobs)
I have tried holding shift at boot and it does nothing and holding alt during boot only shows the hard drive icon, but when i click it im back to stage 1.

Your Mac is attempting to fix your drive and it's not succeeding, you can let it go for some time and see if it clears up.

Do these steps.
If on 10.6 stick a clean and polished 10.6 disk into the computer and reboot holding the c key down.
If on 10.7 hold the command and r keys and boot, you'll enter Lion Recovery Partition.
Under the Utilities Menu is Disk Utility, use it to Repair Disk (note any failures!) and Repair Permissions (ignore list)
See if your computer boots, if not repeat the above steps and use Disk Utility to format a blank external drive, Partiiton Tab, Option: GUID, format OS X extended (J) and click apply.
Next quit and install 10.6/10.7 onto the external drive, when that completes, hold the option key down and you can boot from it. Retrieve your files off the internal drive to the external.
If you cant' see your internal drive in Disk Utility, it's likely failed.
Sometimes you can software like Data Rescue, installed on another Mac or a external boot drive and "read" the failed drive for any salvagable data, provided it's still working mechnically. Good thing about DataResue supposedly is you don't pay unless it's sure it can recover some of your files. I never used it as I make many backups, or bootable clones.
Mechanically failed drives data can only be recovered by platter dissection, a very expensve process.
There is several ways to read the drive, take it out and place it in a enclosure or use a IDE/SATA to USB adapter cable with another Mac or PC (with MacDrive) or use another Mac and Firewire Target Disk Mode (hold T on the sick Mac)
https://support.apple.com/kb/ht1661
If the drive works and you got your data off of it, you can erase it (use the Zero option, GUID/OS X Ext.J) and reinstall OS X, same user name as before, update, (Repair Disk from disk if on 10.6.8) install programs and return files last (and in that order exactly) your machine will be as close as possible to the way it was.
Lastly, consider making a clone, this way you can simply option boot and use that.

Why is my Snow Leopard 10.6.8 suddenly giving me a gray screen and progress bar after I've turned it on? The progress bar takes 4-5 minutes to complete then signing on with my password and all other operations are normal. Solution? Many thanks.

First of all, do a PRAM reset. If it doesn't help, open Terminal and type:

I was updating my macbook pro and it restarted but didn't boot up. It made it to the gray apple screen with a spinning wheel underneath it. What do I do?

This was happening to mine as well and I had to take it in a few times and they had to wipe it completely. If your computer is more that 5 years old, it may be that it is time for a new one. I suggest taking it in so they can diagnose it!

Help - Grey wheel with progress bar on start up and then Macbook Pro turns of.

So i recently bought a Macbook Pro 13 inch (the lower end). While doing my research i found the smartest thing to have a relatively fast macbook was to increase the ram. I bought http://www.newegg.com/Product/Product.aspx?Item=N82E16820148345 and installed it in my macbook pro. After starting up the macbook, i got to my login screen. However, everytime the computer would try to start up to my account, i would get a blue screen and then be brough back to my login page for the account. I assumed that the RAM was not fitted properly since my research indicated that it was most likely the problem. I re-installed the RAM sticks with more force but to no avail. Then i even switched the RAM sticks while installing to make sure that either one of my new RAM chips was not faulty but after a while, my MBP refuses to start up. I get the grey apple logo, with a spinning wheel and progress bar. The bar goes a quarter length before the laptop shuts off. I then put it in the original RAM sticks, but the same problem. Apple logo, spinning wheel, progress bar and then powers off. Any suggestions or thoughts as to what may have happened? Thank you!

Last night the electricity went out and my power surge protector was not working so my iMac just force shut downed.
So, when the electricity came back i turned on my Mac but it is *Stuck in the Startup/Boot Screen with a Grey Apple Logo,a Empty Progress Bar with stays for 1 or 2 minutes and a small Spinning Wheel which would Spin Forver! I Have tried the SMC and Pram reset but no use, i have also tried to insert my OS X Lion 10.7 Installation disk and it would not load if i hold the C Key in the Startup, I Have Managed to go to Disk Utility Through "Recovery HD" but the Volume "Macintosh HD" is Greyed out and Unmounted and i cannot repair it. There are some files that i'd like to Recover if there is a way to fix it without deleting files.
**PLEASE HELP ME FIX THIS!**
Details about the iMac:
iMac 21.5 Inch i think from Mid 2010,
OS X Lion installed maybe 10.7.2 or 10.7.3 (im not sure)
