Recently I bought a Mac book pro online, but I was surprised when I received it because there are no DVDs at all with it. Is this normal?

Ziatron-
That is a really great question! It took some digging to find the answer!
On an older Mac, about 2010 or older, you need access to one of:
• The Mac App Store ( such as on a Mac with a working 10.6.8 or better)
• working Recovery HD
• a bootable 10.7 Installer, on thumb drive, Hard drive, or DVD
So for ONE 2010 or older Mac with a bad drive, you would have to buy the US$70 Apple thumb drive, or have previously made a DVD or Hard Drive when you previously downloaded 10.7. Or you re-install 10.6.8 then overwrite it with the downloaded 10.7.
• another Mac with 10.7 installed so you could transfer Recovery HD to the down Mac with "Lion Recovery Disk Assistant"
OS X Lion: About Lion Recovery Disk Assistant
On some 2010 and most 2011 models, if Recovery HD is messed up or not Installed, but you have a working Broadband connection [with DHCP enabled], the Firmware has been upgraded so it will boot from the Internet and do the whole job using "Lion Internet Recovery" as described in the second section of this glossy article:
http://www.apple.com/macosx/recovery/
If no DHCP is available [no Router upstream, either yours or your ISP's], it may not work.

My hard drive died on Mac Book Pro and I do not have the restore disk?

My hard drive died on my Mac Book Pro and do not have the resore disk?

do you have a backup of your data? You can get the discs that came with your mac by calling AppleCare and giving them the serial number of your mac. For a small fee, they will send them to you.

Hello,
Please help to find my stolen mac book pro - 15 inch,
I have only the serial number of it but Unfortunately I did not have iCloud on it, all my data and researches are there,
The Operating System is mac but I don't remember which version (I think it is the latest because it is updated), also windows & VMWare are installed
WHo can help, please contact me...

As Chris indicated, there is no way to track your MacBook without having set up the Find My Mac feature beforehand (and even if you did, it's quite easily defeated) or having some third-party tracking software installed. All you can do is file a report with the police and hope they get lucky. I can only hope that you made backups of your data and "researches", since I agree with Chris that your chances of ever getting the MacBook back are not good.
You posted in the iTunes for Windows forum, by the way; just so you're aware for future questions.
Regards.

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.

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
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a boot failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
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.

Connect the HDD to your MBP. Open Disk Utility>Erase and drag the HDD icon inrt the Name field. The format should be Mac OS Extended (Journaled). Click on the Erase button.
Then try the clone process again. You may use Disk Utility>Restore or a third party cloning application such as Carbon Copy Cloner or Super Duper.
Ciao.

HT1349 why does my mac book pro start up but contunitues to try to load

can someone help with my mac book it starts up logo appeares then the busy signel conuines to try to load but nothing happens?

Try starting your Mac in Safe Mode.
Restart your Mac.
Press and hold down the Shift key immediately after hearing the startup tone. Be sure NOT to press the Shift key before the tone.
Release the Shift key when you see the Apple logo and the spinning-gear appear.
When the Login Window appears, log into your account.
If you Mac starts up, then the issue may be a problem with one of the Startup items, Login items, or a 3rd-party kernal extension (if you got a kernal panic screen during startup.)
If your Mac does not start up, use the Startup Manager to see if the startup disk is detected. Note: By default the startup disk is Macintosh HD.
Try running the Apple Hardware Test. This test is included on the Installation CD that came with your Mac.

On Mac Book Pro start button does not turn it on.

On Mac Book Pro start button does not turn it on.
After some attempts of pressing it finally it turns on.
(Meantime keayboard can be highlighted,but screen is black and I hear noise of shutting down it when I press it).
What can be the cause of this problem? Actually MacBook is new,only 9 months.
Please give me some suggestion what should I do.

It will be complicated to take it to the Apple store as in Georgia (Caucasus)there is not official Apple stores and in addition Mac Book was purchased in UK. I have red some staff here about start button pressing hard for turning it on, I have feeling that now it needs to be pressed hard to turn on. If it would be from the beginning I might think that it's normal,may be,for Mac Book,but initially it needed to be slightly pressed.
Thank you for suggestion.

I cannot retrieve my emails on my Mac Book Pro operating on 10.7.3 Icloud was already workingit keeps asking for password and when i put correct password in it keeps asking for it again and again. This has just started today

Though it's unlikely to be wrong if things were set up properly in the first place, as a check go to Mail Preferences>Accounts and check that the server setting for IMAP (incoming) is imap.mail.me.com (not just mail.me.com).
Your next step either way would be to go to System Preferences>iCloud and sign out, then sign back in again. (You can ignore warnings about data disappearing - your calendars etc. will disappear when you sign out but reappear when you sign back in).

Mac book pro start up noise no screen purchased late 2013

hey soo ,y yr old Mac book pro 15 retina late 2013 model I saw a post from support saying they r having issues with the sleep mode n not waking up.. Soo I remember this happening n then I wiped the Mac with a cloth went over the keys n it shut off n did not come back on... Now I reset the pram bla bla went through all the trouble shooting stuff it makes start up noise now then nothing...

You may try to restart your computer in Safe mode by taking these steps:
- Click on the Apple sign() at the upper left corner of the Desktop, select 'Shut down' from a drop-down menu;
- Wait until your computer turns off, then press the Power button(⌽);
- Immediately after you hear the startup tone, press and hold the Shift(⇧) key. It should be held as soon as possible after the startup tone, but not before the tone;
- Release the Shift(⇧) key when you see a grey Apple sign() and the progress bar below;
This will force the system to perform several maintenance routines and load essential system software.
Once you've seen the Desktop, start a Disk Utility scan to detect and repair file system errors:
- Open Disk Utility application:
1. Click on Finder at the bottom of your Desktop;
2. Select Applications folder from Finder's left sidebar and then open Utilities folder (or press Command(⌘)-Shift(⇧)-U), double-click on Disk Utility icon;
- Choose your main hard drive from the left sidebar ('Macintosh HD', usually);
- Click on 'Verify Disc' at the bottom right corner, your Mac will perform a diagnostic test. Click on 'Repair Disk' if prompted to fix problems, or follow instructions given on the Disk Utility window;
- Once the routine finished, click on ""Verify Disc Permissions"", after it's done, click on 'Repair Disc Permissions';
- Wait until the process's finished and shut down your Mac, turn it back on in 30 seconds;

Hi, I am using my icloud on my iphone but am unable to find it on my mac book pro. It's not under my system preferences like it shows under the setup. Can I download it again? Or something. I just need to backup some files on my computer and am unable.

Hi, I am using my icloud on my iphone but am unable to find it on my mac book pro. It's not under my system preferences like it shows under the setup. Can I download it again? Or something. I just need to backup some files on my computer and am unable.

The minimum requirement for iCloud is Lion 10.7.5 (Mavericks preferred): the iCloud Preference Pane does not appear on earlier systems - the MobileMe pane appears on Lion and earlier but is now non-functional - you cannot now open or access a MobileMe account.
To make use of iCloud you will have to upgrade your Mac to Lion or Mavericks, provided it meets the requirements.
The requirements for Lion are:
Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor
2GB of memory
OS X v10.6.6 or later (v10.6.8 recommended)
7GB of available space
Lion is available in the Online Apple Store ($19.99). Mountain Lion (10.8.x) is also available there at the same price but there seems little point as the system requirements are the same for Mavericks (10.9.x) - which is free - unless you need to run specific software which will run on Mountain Lion only.
The requirements for Mountain Lion and Mavericks are:
OS X v10.6.8 or later
2GB of memory
8GB of available space
and the supported models are:
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Pro (Mid/Late 2007 or newer)
Xserve (Early 2009)
MacBook Air (Late 2008 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
It is available from the Mac App Store (in Applications).
You should be aware that PPC programs (such as AppleWorks) will not run on Lion or above; and some other applications may not be compatible - there is a useful compatibility checklist at http://roaringapps.com/apps:table
