Progress bar on booting up Yosemite

My iMac (11,2) and old Macbook Pro (4,2) now show a 'progress bar' below the  logo when booting up.
Is this normal, or does it indicate something 'wrong' requiring additional tests etc to boot?
If the latter, what should I do?
Thanks.

Did you get an answer for this? I'm having the same issue.

Progress bar when booting after Yosemite install

I Updated my MacBook to the Yosemite. Everything seems to work fine with the exception of booting......When I turn it on it shows me a gray screen with the apple logo and a progress bar like it's loading something. It never did that before.

Thanks

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!

Progress bar when booting

Hello!
Since a few days, whenever I reboot my MacBook Pro, there is a progress bar underneath the Apple logo.
It takes aprox. 5 min now to boot (very slow!), not that normal I guess.
I already tried to repair the hard drive with the disk utility, but it failed. I ran a hardware test also, but everything seems to be alright.
Anyone with some solutions, or experience with this?
Btw, there appears to be a "lost+found", and "damages files" folder on my harddrive now..
Thanks!

This is new in Yosemite, and it's normal.

Grey progress bar when booting up loop

When I boot up my computer, the grey progress bar below the apple logo appears. It gets to the very end of the bar and then my computer shuts off. When I turn it on again, the same thing happens. Is there any way to fix this?

Windows doesnt do the same system checks that OS X does, so thats why you wont get the issue witthin Windows.
After you replace the drive, you should be able to put it in an enclosure and then migrate the data over to the new drive.
As far as your Windows partition. You may be able to use Winclone (www.twocanoes.com) to image and restore it. I don't know if it will work though when the drive is connected externally.

Deep Sleep - Is it normal to show a grey progress bar during boot?

I've just downloaded the Deep Sleep widget from Axionic Labs. So far, it works wonderfully.
I really like the idea of Deep Sleep. No power consumption, quick boot and same state it was before Deep Sleeping.
However, I noticed that when I power my MBP on (after Deep Sleeping) it shows the grey boot screen with a grey bar below being filled. Actually, it's several small grey bars being filled.
Is it normal to show those grey bars when your MBP is booting after a deep sleep?
Here's a photo that I took of it: http://img198.imageshack.us/img198/2039/dsc00787uz.jpg

Grey progress bar on boot

My Mac Pro restarted several time last night due to power outages during a storm.
Now when I boot it there is a progess bar under the spining wheel on bootup.
Boot process takes longer then usual as well.
How can I fix this?

Almost seems like it is stuck in a loop of starting to Safe Boot. Try resetting the PRAM and SMC.

OSX 10.10: Is it normal to have a loading progress bar at each startup

My MBP-13 (Mid 2010) has become very slow on startup and each time I start (from cold or re-start) it has a "process bar" as if an update is loading, on the Grey Screen where previous to the update there was just the Apple Logo. This began when I upgraded to Yosemite. Admittedly, my hard drive is a bit full (51 GB remaining) and that could be partly to blame for the slower startup, I feel like something is not quite right since the update. Earlier today on the left pane of my finder window, there were 5 versions of this MBP under the "Shared" column (5 versions of itself!). I thought this was strange so I did a restart and while it did take care of the 'ghost' shared versions of itself, it was still slow to startup again, and the progress bar was there again during the grey screen part of the startup process, as it is each time the computer starts.
So My questions are:
1. Is it normal to have that progress bar during startup with Yosemite when it was never there before the update?
and
2. What would cause this computer to show what I like to refer as 'ghost' versions of itself under the shared column on its own finder window left pane?
Thanks in advance for any wisdom you may impart.
Regard,
Capt Ron

1. Yes, the progress bar replaced the spinning gear. Haven't a clue why, but might be to mimic iOS devices ( I don't have any, so can't check).
2, Can't answer, since I share nothing.

Progress bar on Yosemite boot: need I worry?

I just installed Yosemite on my laptop. My wife's laptop is identical, but I haven't yet installed Yosemite on hers. Before I do, I thought I'd ask.
With Yosemite installed, I see that, when I boot, there is a progress bar each time before the logon prompt appears. My laptop specs:
13-inch MacBookPro, purchased in Mid-2010;
Processor: 2.66 GHz Intel Core 2 Duo;
Memory: 4 GB 1067 MHz DDR3;
Disk: 256Gb Flash (81+G free)

Thanks Clinton. That's good to know.
Re: Spotlight. As with most things produced by Apple, the solution was simple - but of course not self-evident.
Thanks to WestonGallagher for the solution. <<Re: Spotlight - How do I access the tool?>> Once the advertisement for Apple comes up, simply starting to type opens up the Spot-light application and the search results are immediate. It would be nice to have a cursor show up in the window that pops up. That way I might have known to start typing. Now that I know how it works, it is very slick.
Thanks again!

During boot Yosemite shows a grey screen with the Apple logo and a progress bar - is this normal?

During boot Yosemite shows a grey screen with the Apple logo and a progress bar - is this normal?

Same here after upgrade yesterday.
I can get OS utilities up using CMD R or holding the shift key (eventually), but if I simply then reinstall the OS will it not loose everything on my drive? I do have it backed up on Time Machine? What a nightmare - Apple Support does suck. I am not paying £25 for them to call me to tell me how to fix a bug in their OS software upgrade. Any help
Also does anyone know if it is possible to use time machine to go back to Snow Leopard? I have wasted much of the day on this now
Cheers

Black screen/progress bar with Yosemite startup

Since installing Yosemite on my relatively new imac, when I boot up i get a black screen with the Apple logo and a progress bar, which takes about 90 seconds to load. I've tried disc first aid, verify/repair permissions etc , done a new install from my backup disc but it still persists. is this now the way of the yosemite world?
Thanks
Bruce

Try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear and again when you log in. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer. For each disable/delete, you will need to restart if you don’t do them all at once.

Yosemite Restart Stuck At Progress Bar

Okay so I installed Yosemite yesterday, and it was working well until my mac suddenly froze in black screen, so I had to force shut down by pressing the power button for 10 seconds.I restarted my mac, and now it's stuck on the booting screen (apple logo and a progress bar), I tried force restarting multiple times, but the progress bar always gets stuck at 50%. Please help!

Verify disk and file permissions using Disk Utility and then reboot normally.

Boot continues to fail - gray screen apple logo progress bar...

I have a mid-2012 MBP. I upgraded to Yosemite. Things were working well. Laptop wasn't used for a week - sleep mode was in use and battery drained. Upon boot-up, progress bar took longer than usual, and after 15 minutes or so it inched its way to the halfway point and finally got to my desktop. Sleep mode is great and I kept the battery charged and didn't let it drain. I needed to do a restart from some updates, but restarting took forever again. I booted off my usb3 yosemite installer and ran disk utility to repair permissions and repair disk. Both found problems and the repair to the disk said I needed to backup any files and start over.
So I got a smaller SSD and installed Yosemite on there, and did a migration to the new SSD. Everything seemed great and snappy for a few days, but once again, after using it in sleep mode for those few days, now it takes forever to start up. I rarely ever restart the Mac, it's awesome. But, the SSD was too small for all my iTunes backups and apps - so I got a 512GB SSD and decided to start over. Once again I installed 10.10 and migrated my data, this time from my time machine backup (few days old). It worked well for one day. ONE DAY. And then it wouldn't even boot. It was slow once, then the next time the stupid progress bar makes it 1/3rd of the way and just quits there. Disk utility finds no errors now, but it won't boot up.
The screen dims, the cursor appears, but the screen with the progress bar remains for about an hour until it brings up a screen full of text stating startup wasn't successful in a dozen languages and then it reboots. Over and over it goes.
When I boot off the usb install, the same progress happens, 1/3rd of the progress bar fills, screen dims, cursor appears, but eventually it turns into the spinning rainbow and the progress bar finishes. I never make it to the rainbow part.
I have reset PRAM as well... Tried different Apple certified RAM. Not sure what steps to do next, so I'm reinstalling Yosemite as I type this.
The 512GB SSD and the smaller SSD were both used in windows machines for at least 6 months prior to use in the Mac, so I'm positive they are good drives. Now I'm not sure if my original HD was even defective or not. Does anyone have any suggestions of things to try or what the problem might be? TIA.

If you can't start up and log in in the usual way, try in safe mode.
During startup, you’ll see a progress bar, and then the login screen, which appears even if you normally log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Log in as an administrator to carry out these instructions. If you have only one account, you are the administrator.
☞ If you don't see any reports listed, but you know there was a panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
Safe mode is slower than normal, and some things won’t work at all.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t start in safe mode.
If you're able to log in, launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
In the Console window, select
DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report.

After a series of very short power outages in my town our Imac boots with the pinwheel going and a progress bar, then the users screen comes up but our passwords no longer opens up desktops, just returns to the users choice screen. What should I do?

I'm on the choose a user screen and when I enter the password the screen goes white then returns to choosing a user. The system is rebooting differently when I tried turning off then back on, the pinwheel screen has a progress bar and it takes minutes instead of seconds.
what should I try?

You can try an SMC reset, especially if there was a power outage.

If the issue seems like it just doesn't want to accept the password you'll need to boot to the install disc/recovery partition of the hardrive by holding the 'option' key while booting up. There should be a utility in there to reset your password.

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.
