Slow boot on mbp running 10.6.4 with progress bar

Hi
My Macbook pro running 10.6.4 has recently become slow on boot up.
When i do a clean boot or restart i see a progress bar on the apple logo which now seems to take a minute or so to load.
I've never seen this before.
I've tried things such as PRAM reset, cache clears, etc
disk utility isn't showing any hard drive errors
any suggestions?
Ian

Hi I,
You can check for any boot arguments in your /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
If you have any Kernel Flags your Mac will observe it when booting, mine has no Kernel Flags.
You can read about it by using de command line "man com.apple.Boot.plist" in your /Applications/Utilities/Terminal application. After reading hit Q key to quit the manual displaying and use "exit" before quitting Terminal.
I made a quick search and found this 54 replies topic here, it seams to be an update issue, check it out, http://discussions.apple.com/thread.jspa?threadID=2141922&tstart=1
Good luck.

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!

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.

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.

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

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!

Slow boot/startup MBP after Mavericks upgrade

Hi Macbook Pro users out there!
Since upgrading my MBP Mid 2009 from Mountain Lion to Mavericks, a simple system restart takes about 3-5 minutes, compared to about 15-30 seconds before the upgrade. Most of the booting time ist consumed after entering my password.
Some more technical details:
* MBP equipped with SSD and 3.01 GHz Intel Core Duo
* I did a "clean" install from an Mavericks image and used a time machine backup to reinstall apps & docs
* I switched ON file-vault
* volume check shows no errors; access rights check shows a lot of issues, but they cannot seem to be repaired (tried this several times!)
* only few background processes running and no active applications
Does anyone of you have a hint or advice for me, how to speed up the system-boot process? Everything worked perfectly with Mountain Lion. Is anybody experiencing similar problems? What exactly happens after entry of the password, besides loading of active apps and processes? Is there a way to find out, which part of the boot process takes so long?
Thank you for your help in advance!

I have a new Macbook Pro 15 Retina, and since installing Bootcamp I have a 3 minute boot time before my password. Bootcamp installation was quite a chore, so I am not wild about wiping out the machine for a clean install, especially if this is a product of Mavericks (I would get the same result). The original clean machine booted in 20 to 30 seconds...just a bit longer than my 2010 MB Pro with Snow Leopard and Bootcamp. I assume there is a diagnostic tool to figure out what is slowing the boot, but I have not found it yet.

Lion Slow Boot on MBP 2010

I have a Macbook Pro (mid 2010) with i7 4GB ram with OS X Lion (installed correctly) with Windows 7 on bootcamp. It takes me 1 minute to boot into lion but before with snow leopard it took me less than 30 seconds. My friends who have lion also take 30 seconds or so. I have regularly repair my permissions and clean cache and cookies with CleanMyMac. I have also run Apple Hardware Test (AHT) and reset my PRAM. All went okay and there wasn't any difference. Is bootcamp effecting my Lion boot time ?
Thanks,

[Boot Camp] Trying to partition for Windows and progress bar remains with "Status : Idle"

I'm trying to setup WIndows using Boot camp on my iMac OS X10.7.4. It worked perfectly fine until yesterday. I don't have a OS X installation disc or something to re-install or something. But wanted to know meanwhile, if there is someone who can provide inputs on fixing this issue? I tried to do the following -
1. Repair Disc Permissions [Didn't Fix th Issue]
2. Force Quitting the Applications and Restarting [iMac did not shutdown/restart at all. Did a force reboot, still didn't work!]
3. Verifying and Repairing the Disc [No Problems Found]
Its really important for me to get this working by today!
Thanks for your patience and persistence.

So your problem I gather is you don't know how to use Lion Recovery Mode; don't have a TimeMachine or other backups.
Force hard shutdowns never have good outcome.
Maybe you should skip Windows native install and stick to use a VM
http://www.apple.com/support/lion/installrecovery/
http://support.apple.com/kb/HT4718
https://support.apple.com/kb/HT1427
I recommend shrink Mac volume (Lion Recovery: Option "Recovery" or Command-r)
Then stretch back to full size again - after you have backups

Speakers on MBP C2D Are basically mute with three bars left to go.

I just got a new MBP C2D and when I turn the volume down, it is extremely quiet at half level, and with three notches to go, it is silent. My friends does the same thing. Is this normal, or should this be fixed?

Mac. MobileMe-to-iCloud. Upgrading Mail Database process seems to be hung - has been running for over 1 hour - progress bar stuck at about 20%.

Am wondering whether to 'Force Quit' and restart, or to let it keep running. Noticed that Activity Monitor is reporting very use of CPU (98% to 100%) of an activity named as "AddressBookSourceSync". Am not sure if that's related to this issue. Any suggestions? Thanks....

Win XP slow boot problem solved

Hi guys,
Just want to share my discovery re: slow boot.
For Win XP Pro users with 1 HDD:
1. Go to Device Manager
2. Select IDE Controller
3. Select Primary Channel (assuming HDD is connected to IDE1 which according to the MSI manual should be the case)
4. Click on the Advance Setting Tab
5. On Device 1, Select None for Device Type and click OK
6. Wait for a while because it takes some time for the window to close
And that's it !!! I did tried the bootvis optimization first but only about 5 seconds were taken off from the start up. I also took out the jumper in my WD HDD and even replaced my IDE cable. Before my discovery, it took 2 mins to boot my PC. Now it only takes 30 sec (i.e., from Win XP logo to desktop).
Hope it works for you guys. Good Luck !!!

Slow graphics on iMac running 10.8.3

I recently installed Paraview on a new iMac with 10.8.3 and the graphics performance is slower than expected. Running the same software with the same data file on my older macbook pro laptop (running 10.7) resulted in better 3D graphics interaction, even though the graphics card on the iMac is better on paper. My laptop has an AMD Radeon HD 6770M with 1GB memory while the imac has "faster" NVIDIA GeForce GTX 680MX with 2GB memory. Has anyone else had issues with 3D graphics while running mountain lion (10.8)?
-James

Hi,
i have an iMac from 2012, and a Macbook Pro 13" from 2012 and, after upgrading to 10.8.3, i began to experience some poor graphic performance. When i switch between desktops it does it slower than before (wich it was excellent).
I have Mountain Lion 10.8.3 and i use my computer for graphic work (photoshop and similar), so it's a very annoying and notorius thing.
If anybody knows how to fix this, be my guest and thanks from now!

Why is Safari running slow on my MBP?

It just recently started to slow down. A few hours ago, I experienced it so I just turned off my MBP to, hopefully fix it, but Safari is still going slow. Yesterday, it was running fine and I was loading up pages fast. Now, when I ever I go to a new page or click a link, it pauses and the address bar above loads to about 3cm and the spinning color wheel spins for about 5 seconds until the new page loads. It does it for every thing I go to. Trying to ask this question probably took a minute to get to when it should only be a few seconds. I've tried Google Chrome and Mozilla Firefox and it is fine. When I enter a web address or click a link, in a few seconds, the new page shows. I really don't want to move to a new internet source because all my bookmarks and saves is on Safari. Is there a way to fix this?

Since Safari freezes before you can troubleshoot, boot in Safe Mode then try troubleshooting Safari extensions and third party plug-ins.
Startup your Mac in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test. If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow all other plug-ins. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.
Once you are in Safe Mode, click Restart from the Apple () menu.

MBP running Mac OSX Leopard 10.5.8 cannot get past login screen even in safe boot

Help! I have a Macbook Pro purchased in 2009, running Mac OSX Leopard 10.5.8 which froze while running Adobe Illustrator. On reboot, it won't allow me to go past the login screen. I tried starting up from the disc, running disk verification and repair and repairing disk permissions, and trying to start up in safe boot, all to no avail. When the login screen comes up it gives the name of my hard drive with a (2) after it, which seems strange. Any suggestions short of reinstalling the system software? I don't want to lose my applications/data!

My MBP takes drastically longer to boot when i turn it on as opposed to when I just got it. My web pages take a long time to load. Can anyone help me? WHat can I do to speed up my MBP. I am a novice mac user. Again my mac is getting slower by the day and i dont know how to increase its overall performance. Is there any simple software that can boost overall performance or will I have to reformat my MBP? I have a 200gb HD with 50 gb free and 4 gb of ram.
Welcome to Apple's discussion groups.
Launch the Activity Monitor utility. Pull down the list near the top and set it to "All Processes". Click on the "CPU" column heading to put the highest CPU consumers at the top. Also click on the "CPU" tab in the lower part of the window to check the value for "% Idle". If that value is much above zero, check the other categories for signs of resource problems. If nothing there points to a possible problem, launch the Console utility and look for messages that might suggest a problem. If you see messages that you have trouble interpreting, post them here and someone should be able to help.
