Hello and welcome to JustAnswer. I look forward to assisting you today with your question and providing the best answer possible.What OS are you running? ie. 10.5.6 or 10.7.2If you click on the Apple icon in the top left and choose about this mac. It will tell you the version number.
mac os x 10.6.8
After working on the mac yesterday, I was finally able to get it to boot up, but it's not quick. It will boot to a blue screen and sit on that screen for about 3-5 minutes before giving me the login screen. Once the login screen appears it takes another 1-2 minutes before the keyboard starts working.
Shut down your Mac if it is on. Press the power button to start the computer. Immediately press and hold the Command (Apple) key and one of the following:
When it stops loading. Let me know what the white text says.
It's an entire screen of verbage. Do you want me to type it all out, or is there a certain line of text you are looking for?
Hello?
Just type the last line, I want to see where it gets stuck

I did as you said. Upon reboot I started a stop watch. It's now been 7 minutes and the screen is still blue.
The login screen finally appeared after 10 minutes.
Restart again and let me know if it takes the same amount of timeAre you using wireless or wired connection?Is this type of macbook the one you can take the battery out or not?
I restarted; it took 10 minutes to get to login screen.It is a macbook pro (all silver keys) using wireless connection.It does have a removable battery.
?? What is the next step?
If the computer is on, turn it off.Disconnect the AC adapter and remove the computer's battery.Press and hold the power button for 5 seconds and then release the button.Reconnect the battery and AC Adapter.Press the power button to restart the computerI would also reset the pram. To do so do the following:Step 1: Shutdown your computerStep 2: Locate the following 4 keys on the keyboard: Command (Apple key) , Option, P, and R. You will need to hold these keys down simultaneously in step 3. You must do step 3 prior to the Apple logo from appearing on the screen otherwise you must shutdown and try again.Step 3: Turn on computer and immediately hold down the Command (Apple key ) & Option & P & R key all at the same time. Keep holding them down. The computer will restart and on the third time you hear a chime you can let go and your computer will start up as normal.

It never gets to the logon screen. It is stuck on the blue screen now.
In your first post, you wrote that you ran disk repair. When you booted off the cd and ran disk repair. Did it find any issues?
I went into DIsk Utility and did verify and repair permissions. It did find things when I ran verify, but it said it repaired them after I hit repair. Should I run that again?
I rebooted and the logon screen appeared after about 9 minutes this time.
I would boot off your disk and run the disk repair again. Let me know if it finds anything.
When I run verify disk it says "The volume Macintosh HD appears to be ok"

Ok, I reinstalled Mac OS X and it seems to be much faster at working. It doesn't hang on the blue screen. However, once the logon window appears nothing works. I cannot hit the return key to logon (there is no password), i cant select "login" with my mouse.

I turned the macbook on this morning and it is back to being stuck at the blue screen which then turned black. I hit a key and then the logon screen appeared, but the keyboard won't let me type a password.
Does it boot in safe boot?
Yes it boots in safe boot
I appriate your patience. I know it is a lot of back and forth. I need to take a look at the system log to try to find out why it is only booting in safe boot. Please do the following:Click on the picture of a face all the way on the left-hand side of your dock.Click Go all the way at the Top and Choose UtilitiesOpen ConsoleAt the top Click File and Open system.logThis will tell you everything that is going on with your system.Click on File and Save a copy as.

Do I do all this in safe mode?
I booted it in safe mode and did as you said. Here is the download link: http://wikisend.com/download/255682/system.logAnd here is the forum link: system.log
Click on the Apple in the top left of the screen and choose software update. Please run all the updates. Restart computer. If it still has trouble after the updates. Please disable mobile me by doing the following:Also disable mobile me by doing the following:
Choose Apple menu > System Preferences, and then click MobileMe.
Click the Sync tab, and then click Advanced.
Select the computer you want to stop syncing.
Click Stop Syncing Computer, and then click Stop Syncing Computer.
All software is up to date. There is no mobile me on this macbook.
It is giving mobile me errors i the console which is why I asked. Click on the picture of a face all the way on the left-hand side of your dock. Click on Go at the very top and Choose HomeThis will bring up your home folder. Go into a folder called Library and then another folder called LaunchAgentsDelete anything in here that has MobileMe or .mac in the title. If there is nothing there with that in the title please let me know what files are listed. Words listed before the third period. ex. com.adobe.ARM.asdflakjsdfs.plist I just need to know com.adobe.ARM
There was only one file in that folder, it was called:com. apple. CSConfigDotMacCert-marveyhushman @me.com-SharedServices.Agent.plistShould it be deleted?
Yes delete it and restart
Ok, I deleted the file and restarted. It is still sitting on blue screen (its been 5 mins now).
It just booted up. It sat on the blue screen for about 10 minutes prior thought. Should I do something else?
If you go back to the Library Startup folder from above. Is anything listed there and if so what?
I restarted, but the mouse doesn't work now. I will restart in safe mode and check the library startup file.
After rebooting in safe mode, I looked in HD/Library/StartupItems and the folder is empty.
Do you have an external drive connected or any usb/firewire devices?
No, nothing external is connected.
I'm not sure if my last message went through. I boot up the mac now and it takes approx 10 minutes to get to the home screen. All 10 minutes it sits on the blue screen. While I am happy that it is finally completing the boot, it takes a very long time. What is the next step in figuring out why the startup is so slow? Thanks again.
From the system log it looked like a firewire device was the issue but it might be your firewire port which is why it boots fine in safe boot.Please do the following:Click on the picture of a face all the way on the left-hand side of your dock. Click on Go at the very top and Choose Computer. Open Hard drive. Open the System folder and then Library folder then Extensions.Move everything with firewire in the title to the desktopRestart
Oh my god Oh my god Oh my god :D I moved the firewire files to the desktop and rebooted and it took exactly ONE MINUTE!!! And the keyboard and mouse work too.So exciting. Do you think this is a final fix? Would you like to see the system log now?Thanks a million!
Great! This looks like the final fix. You have a faulty firewire port. If you ever get an external drive make sure it is usb. Do a restart one more time to be sure.

Does a faulty firewire port also cause the keyboard and trackpad to not work at times? Or was that fixed with something else? Rebooting now.
yes it got hung up trying to detect the firewire port and this caused the usb ports to become unresponsive.
Ahhhh, I see. I rebooted and it works perfect. Boots in 1 minute flat. I cannot thank you enough for all of your help. Is it possible to get our conversation sent to my email? I truly appreciate your time and support, Tom.
No Problem Glad I could help. I'll ask customer service to send this converation via email.
