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

Mac will not load. Shows a screen with a question mark.

My macbook only loads to the screen where a question mark is displayed.
I've tried all the trouble shooting tips such as restarting while holding the command/option keys etc, removing the battery, etc. At the step where I try to do first aid on my hard disk, that will not work. "No valid package" displays as the error. It will not restore or erase either. The installation disk will load but not progress further. The computer can not read the hard drive anymore.
This happened after I left programs running and the computer went to sleep, when I came back it froze and I restarted but to only get this. Help?

I notice the first two replies you've gotten tell you to do things that you say you've already done. There's just no accounting for that kind of behavior -- it's very odd.
To answer your question, if Disk Utility cannot even erase the hard drive, you most likely have a hardware problem. A MacBook hard drive out to be able to report its SMART status, I would think, so try selecting the drive (not the partition, but the drive itself) in Disk Utility. At the bottom of the window there will be some info text -- what does the one labelled "S.M.A.R.T. Status" say? If it says "About to Fail" in red letters, that means you've definitely got hardware issues, and the drive itself needs to be replaced. If this machine is still under warranty, it ought to be fixed by Apple at no cost to you.
If the SMART status says "Verified", that means it's not a hardware issue, in which case it's puzzling why Disk Utility can't even erase it. In that case, I would advise trying a third-party disk utility, like TechTool Pro (http://www.micromat.com/). Perhaps then you could repair it to the point that Disk Utility could erase it. (And, if the damage is this bad, I'd definitely recommend erasing it and reinstalling everything from scratch.)

What's installed on your computer? If you don't have Snow Leopard 10.6.6 or later then you cannot get Lion. If you already have Lion installed then you cannot re-download from the App Store until you have reinstalled Snow Leopard.

Computer does not start up when connected to My Book 4TB

When I connect MY Book (4TB) to my computer before turning it on, my computer does not start up. I only get a black screen. If I disconnect the My Book and then first start up my computer, I am able to plug in My Book and read all the files, backup, etc. Why won't the computer start when My Book is connected???

??? Wrong Forum? This is for "My Book Live" vs "My Book"... How to tell? Easy, MBL (NAS) does not have USB, MB (USB HD) does...

Hi. Unfortunately my ethernet card was not working anymore. This is the message "This computer does not appear to have any PCI Ethernet card. How can I fix it?

i would try an SMC reset, the following article tells how to do this:
http://support.apple.com/kb/HT3964
if it still gives that message, you need to take it to apple store or apple service provider to have a new card installed. the apple site gives listings of providers and stores in your area:

You should reinstall OS X. See the following for reinstalling instructions for Lion/Mountain Lion or Snow Leopard:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Mac OS X 10.6.8 Update Combo v1.1.
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

I am resurrecting my old iMacG5 for my grandson. Appleworks has question mark in dock and does not load from bundled software on original installation discs. Can anyone help?

I'm sorry no-one has answered you yet - I'm afraid I don't know the answer to the question: but I wanted to put into your mind that starting up with AppleWorks at this stage isn't a good idea. The program was 'end-of-lifed' years ago, it won't run on Lion, and some of the document types created in it - Databases in particular - cannot be opened at all by any other program whatever. Word Processing documents can be opened in Pages, and Spreadsheets in Numbers (with some reservations in both cases), but building up a collection of AppleWorks documents at this stage is going to lead to problems later on.
It's difficult to know what to recommend for a PowerPC machine that would still be compatible with modern ones. An older version of Microsoft Office, perhaps, if you can find one which will run on PPC; but most of the modern Word Processors are Intel only. This is something you would need to investigate.

Itunes document manager pro will not open a document with .cwk extension. It will catch the document then error message states that it cannot open document. Can anyone tell me what Im doing wrong?

Forgive my ignorance but I have never hear of iTunes Document Manager Pro. If you mean Document Manager Pro, i was able to find that. Back to your problem, have you tried opening one of those files in the iOS iWorks apps? Form the quick read that I did about this, .cwk files can be opened by Pages, Numbers or Keynote, depending on what type of document that it is and those files can be read by Document Manager Pro, after properly saving them. I don't see that you can go directly from the .cwk file in Document Manager Pro without converting them first.
I took a very quick look at the app, so I may be a missing something about its capability.

TS2094 After resetting the pram, the screen only shows a folder with a question mark inside. What does this mean?

I followed the initial steps in this post and reset pram. After restarting, the screen just shows a folder with a question mark. What does this mean?

Thanks Niel, I tried using Option and nothing happened so I next tried inserting the Leopard disc and rebooting while holding C. Nothing happened until the disc was ejected and then the folder with question mark reappeared. I inserted the disc again and at this point and it booted OSX. I tried to acess disc utility to repair but my harddrive wasn't listed, only the CD drive and the OS disc. Does this mean I'm lost everything?

Can anyone tell me what this Time Machine error means? The network backup disk does not support the required AFP features?

Can anyone tell me what this Time Machine error means? The network backup disk does not support the required AFP features?

AFP - Apple Filing Protocol
The Network Attached Storage (NAS) that you are pointing Time Machine at does not have the features needed by Time Machine in order to do its Thing. Time Machine needs some specific features that are not typically available on generic networked storage devices.
There are manufactures that support the Mac OS X HFS+ file system formats and implement all the needed AFP protocol packets necessary so that they can be used with Time Machine, but apparently yours does not.
If you are not using a networked mounted volume for Time Machine, then more information will be needed about your Time Machine setup.
