I have a mac book pro i want to have another monitor added and open garageband with 2 projects open is this possible.

I have a mac book pro I want to use 2 monitors and have garageband open with 2 projects is this possible?

GarageBand can open only one project at a time. Project are treated differently from audio files; you can have many audio files open in QuickTime or other audio players, but GarageBand will always close the current project when you open a new one.
If you have the newest GarageBand 10.0 and the previous version, GarageBand '11, version 6.0.5, you can open one project in GarageBand 10.0 and one project in GarageBand '11.
However, you cannot drag and top between the windows or transfer media. And once a project has been converted to GarageBand 10 format, it can no longer be opened by GarageBand '11.

I have no idea how much it will cost to repair. I don't even know what the exact problem will prove to be. It may be quick if it isn't a motherboard problem. I just don't know. Take it in for a service diagnostic, then they can tell you what is involved.

What is the exact model of your Macbook Pro?

Mac Book Pro will not start on Battery Power

Mac Book Pro will not start on Battery Power although battery at 98% need to connect charger. When started date and time incorrect, comes up as 1st Jan 2012.

What is the exact model of your MBP? The date change often is an indication of power loss to the MBP, such as disconnecting the battery.
If the SMC reset does not solve the situation, post this from your MBP:
Make certain that the power adapter is connected.
Ciao.

My Mac Book Pro wouldn't start after memory update

I updated my 27" Imac memory up to 16 GB, so I was encouraged to do the same with my Mac Book Pro after watching the video and instructions. However My Mac Book Pro wouldn't start afterwards. It is driving me crazy. Please if someone can help me on this. Thanks

I was trying to install Corsair 8GB (2x 4GB) 1333mhz PC3-10666 204-pin DDR3 SODIMM Laptop Memory Kit CMSO8GX3M2A1333C9; and now I realized that I made a mistake because this Mid 2010 Mac Book Pro uses 1066mhz PC3 8500 instead, so should that be the problem of compatibility? I should guess so, although in my HP Elite I have 800Mhz ddr2 where the bus works at 640 mhz ddr2.
The rest is the same being 204 pin memory cards, etc.
I made this mistake because ordered at the same time this memory along with memory cards for my new 27" iMac, which works at 1333Mhz.
Thankyou again, I will check on if cards are sitting well and if they are PC3 8500 1066 Mhz....

It may very well be a RAM issue but possibly something else. Look over this extensive troubleshooting document for a possible solution:

My mac book pro does not start but has error message with a question mark on screen. took it in and was told probably the hard drive as could not reconize it so bought new one but still not connecting.what do i do

My mac book pro does not connect but shows an error message with a question mark on the screen.I took it to a retailer that said it was not reconizing the hard drive.He said i needed a new hard drive but it may be something else as well but he was sure a new hard drive would fix it.So putting faith in someone who deals with them i purchased a new hard drive to find it was still not working although he said the computer did know reconize the hard drive and i may have to send it away to get it checked .After already paying 120 pounds for a new hard drive and they wanting another 80.00 pounds to diagnose it i am a little sceptical.
That's why i am interested on anyone's help.

Welcome to the Apple Support Communities
I think that your Mac detects your hard disk, but the problem is that your new hard disk doesn't contain any operating system, so your Mac doesn't find any bootable partition and you see a question mark.
If your Mac came with DVDs, insert the Mac OS X Install DVD and hold the C key while your Mac is starting. Then, just install Mac OS X. If the hard disk isn't prepared to install Mac OS X, you will have to erase it using "Mac OS Extended (Journaled)". See > http://pondini.org/OSX/DU1.html

Help My mac book pro does not start

i have a huge problem becauce i cannot start my mac book pro, i turn on and apear the gray screen with apple logo and round progresive bar, but just not have any change it cud be hours or days its the same, i already try to restore it by the comands (command+R) or (shift+caps lock) when i turn on my computher but alwais same logo screen, please i need help maby im doing someting wrong

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
Step 3
Boot in safe mode. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually 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.
When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 4
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 5
Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
Step 6
Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 7
Repeat Step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
Step 8
This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. Both desktop and portable Macs used to have such a battery. The logic-board battery is separate from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 9
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested. If you can't get to an Apple Store, go to another authorized service provider.

Mac book pro stuck at start up screen

Mac book pro was running slow so restarted it and now can't get past start up screen. Any tips?

Force Quit (under the Apple menu).
Can you get any MS Office app to open without freezing? If so, you should go under the Help menu of any Office app and select "Check for Updates" - the latest version is 14.3.9.
You might also want to try holding down the option key when you next try to open Outlook - this will force a rebuilding of your user database. You may have a problem there.
If all else fails, you can always trying uninstalling Office 2011 (http://support.microsoft.com/kb/2398768?wa=wsignin1.0) and reinstalling it...

HT4061 iTunes will not open when my iPhone 4S is attached to my Mac Book Pro. iTunes will start up but as soon as my iPhone appears in the list of devices the program then quits and displays the message 'iTune Quit Unexpectedly'? Can anybody help?

The Problem/s
1. I am unable to sync my iPhone 4S with my Mac Book Pro, either by cable, wifi or bluetooth
2. iTunes will initiall open and briefly identifies the iPhone in the Device section in iTunes.
3. When iTunes starts to read the iPhone (displaying the spinning wheel), it immediately then quits and
4. Opens a 'dialogue box' which displays the message "iTunes Quit Unexpectedly"
5 The dialoge box offers the following button options to:-
'Show Details'
The 'Show Details' button will open and display a list of the 'Problem Details and System Configeration'. To the average user the information is useless, as one doesn't know what to look for to solve the problem. This is a long and detailed report (too long to include in this message), which includes information such as:-
Crashed Thread: 20
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x00000000000006f0
'OK'
The 'Ok' button simply quits and closes the dialogue box
'Reopen'
The 'Reopen' button will again reopen iTunes, briefly showing that it is trying to read the iPhone in the Devices section, but then returns again to display the same dialogue box.
Other Information
1. iTunes will still start normally once the USB cable is removed from the Mac book Pro, but crashes again once the USB cable is reattached to the computer
Any advice or help offered would be greatly appreciated.
Sincerely
Rob

You placed the users files into the Trash can and then Finder > Empty Trash, this sends a message to the other drive that the files don't exist anymore.
If you can't Trash the files it doesn't matter really.
Unmount the drive by dragging it's icon to the Trash can turns into a Eject.
Now on the problem Mac you boot holding the Shift Key down, this enters Safe Mode and should hopefully get you into the machine to delete files. Reboot normally to exit safe mode.
If you can't do this, then it depends upon what operating system is on the machine, you either need the 10.6 boot disks or can hold Command R and boot into RecoveryHD and then erase the MacintoshHD partition and reinstall OS X, your programs and files from backup.

MAC BOOK PRO WILL NOT START- COMPLETELY DEAD!

I forgot to power down my mac book pro last night. I closed the lid & forgot to go back & turn it off completely. This morning it will not power up. The machine is completely dead.
The power supply wasn't connected overnight so I assume the battery has completely drained. It's been charging for the last 2 hours (which would normally have fully charged it) but the light on the power cord is still showing green so I assume it's still charging, however there should be plenty of juice in the battery to start the computer but it still won't start.
Any ideas how to get it started?

A dead battery will take longer to start charging, but leave it on and eventually it will start to charge again.
Once you get it charged, perform a SMC and PRAM reset
