Hello
I have a macbook pro 2011 13" that came with OS Lion (integrated not on a disk). I recently bought OS Mountain Lion of the app store and it is working fine. However I was a bit dissapointed in the battery so I decided to try and downgrade and completely failed, I froze the computer and when I restarted it it did not work. I went into recovery system and erased my disk and all that and went to re-download my OS. I was expecting to get the option to re-download Lion but instead I could only re-download Mountain Lion.
My question is since my computer originally came with Lion can I reset my computer so I get OS Lion back instead of OS Mountain Lion?
Thanks for any help. Any answer will be appreciated even if it is saying it is not possible.

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.
Erase the hard drive:
    1.    Select Disk Utility from the main menu and click on the Continue button.
    2.    After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
    3.    Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
    4.    Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install 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 working on a MacBook Pro (13-inch, Mid 2009) with boot camp running Windows 7 pro 64-bit. Windows crashes quite often now-a-days and I need to get this fixed. I heard that updating boot camp can help. Currently I am running Version 3.0.4 (322).

I need to know which update(s) I can apply to help stabalize the system.

Typing the body of the thread message in the title, huh? -)

Only Apple could hamstring and tie Mac OS to Windows. There isn't any other than whether you can download the drivers into Windows (you can) but Apple puts a block on the installer setup even if your mac does not support it.
Windows 7 needs at least Boot Camp 3.1 and 3.3 is what you should already have. And you are not getting security updates if you don't have at least 10.6.8 as was pointed out. --- you arent using Software Update as you should. And you should backup and clone Mac (and Windows) as well.
You need Mountain Lion to use Boot Camp 5.x which supports Windows 7 & 8 and 64-bit.
I would upgrade to Lion if you can realizing that Rosetta and PowerPC are no longer supported though.

Is there a download of the Boot Camp 5 Support Software if I'm not using OS X Mountain Lion v10.8.3?
Yes, you can download the Boot Camp 5 Support Software here.
http://support.apple.com/kb/DL1638
How do I use the Boot Camp 5 Support Software I downloaded from the web page?
The download file is a .zip file. Double click it to uncompress it.
Double-click the Boot Camp disk image.
Copy the Boot Camp and "$WinPEDriver$" folders to the root level of a USB flash drive or hard drive that is formatted with the FAT file system (see question below for steps on how to format).
Install Windows, leaving the flash or hard drive attached to the USB port of your Mac.
Installation of the drivers can take a few minutes. Don't interrupt the installation process. A completion dialog box will appear when everything is installed. Click Finish when the dialog appears.
When your system restarts your Windows 8 installation is done.
Note: If the flash drive or hard drive was not attached when you installed Windows and was inserted after restarting into Windows 8, double-click the Boot Camp folder, then locate and double click the "setup.exe" file to start the installation of the Boot Camp 5 Support Software.
How do I format USB media to the FAT file system?
Use Disk Utility to format a disk to use with a Windows computer. Here's how:
Important: Formatting a disk erases all the files on it. Copy any files you want to save to another disk before formatting the disk.
Open Disk Utility.
Select the disk you want to format for use with Windows computers.
Click Erase, and choose one of the following from the Format pop-up menu:
If the size of the disk is 32 GB or less, choose MS-DOS (FAT).
If the size of the disk is over 32 GB, choose ExFAT.
Type a name for the disk. The maximum length is 11 characters.
Click the Erase button and then click Erase again.
Which versions of Windows are supported with Boot Camp 5?
64-bit versions of Windows 8 and Windows 7 are supported using the Boot Camp 5 Support Software. If you need to use a 32-bit version, you need to use Boot Camp 4 Support Software, and you must use Windows 7. 32-bit versions of Windows 8 are not supported via Boot Camp.

The single download means that you won't be able to redownload it from the store without paying, either on a computer's iTunes or an iOS device - it doesn't stop you from copying the audiobook to your other computers or syncing it to your iOS devices, you just can't redownload it. (I believe that they are all supplied to Apple by audible.com, so I assume that it's them requiring the one-time download.)
You can download audiobooks on your computer's iTunes and sync them to iOS devices, you do not have to buy them directly on the device (if you do then you can copy them back to your computer's iTunes library by connecting the device and using the File > Devices > Transfer Purchases menu option on your computer's iTunes).
What you are doing to sync them should work i.e.
- connecting the iPad to your Mac
- selecting the iPad on your Mac's iTunes
- selecting its Books tab and selecting the audiobooks that you want to sync to the iPad and syncing/applying that selection.
You should then get an audiobooks option in the Music app on your iPad. If they aren't appearing there then do they show in Settings > General > Usage > Music on the device - if you have audiobooks on the iPad then they should be listed there under an 'audiobooks' heading.
By 'restart the iPad' do you mean a soft-reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
You could also try closing its Music app via the iPad's taskbar : Force an app to close in iOS.
And do a soft-reset and retry syncing.
I assume that music and other items sync ok ?

Selling macbook Pro 2011. It came with Lion, I upgraded to mountain Lion and Mavericks. Can license be transfer to new owner? how?

selling macbook Pro 2011. It came with Lion, I upgraded to mountain Lion and Mavericks. Can license be transfer to new owner? how?

Good question now that Mavericks is free to all.
It used to be - and is probably still the case - that to comply with the license you should erase and re-install the OS that came pre-installed on the Mac when new. If there were restore disks they needed to be passed on with the Mac.
I'm happy to be corrected on this by someone who's more au fait with the legalese, but an upgraded OS is tied to an AppleID whereas the original OS is tied to the computer, not an AppleID.
My guess is, that if you launched the Recovery HD, erased the drive using Disk Utility and re-installed the OS, Lion would be installed.
Be interesting to see what others say.

How to make a MacBook Pro (mid 2009) work properly with a 3M Streaming projector?

Ok, so I have a MacBook Pro (mid 2009), a 3M Streaming projector and very annoying problem.
When I connect my MacBook Pro with a Mini Displayport to HDMI adapter to the 3M projector, I get a pink tint, like a filter over the image, it’s very frustrating.
This are the tests I’ve done:
1. I tried the adaptor and the projector on a different (more recent) Mac -> It worked fine.
2. I tried connecting my MacBook Pro to a different not HDMI but VGA projector -> It worked fine.
3. I used some Terminal code I found on the web to force the Mac to send RGB signal, don’t know if that has anything to do with it, but I tried anyway -> Didn’t work
So I’m confused, it’s not the physical port of my MacBook cause it worked fine with a VGA projector, It’s no the 3M projector and it’s not the Mini Displayport to HDMI adaptor cause it worked fine on a different Mac.
So what is it?
I’m totally desperate, I haven’t been able to solve this problem, so if you guys can help me you will be my heroes.
Thanks.

Yes as Clinton says this is correct.
I've used a Sata to USB connector which is only a few pounds instead of an enclosure for the clone, but then I wasn't keeping mt old HDD. But that's an option if you don't need it.
I also use Carbon copy cloner as this will clone your recovery partition as well. Apples disk utility will also clone drives but I'm not sure that it copy's the recovery partition.
I highly redomend my Samsung 840 pro 256Gb - it's about the fastest drive you'll get (nearly) but is backed by Samsung's unrivaled SSD reliability and 5 year warranty. I've also used an 840 basic model on an older macbook and was equally pleased.
Crucial's drives are reliable mac friendly drives but are somewhat slower on the write speeds vs the 840 Pro.
I'd avoid OCZ drives due to so many failures across their range although they do have great reviews and some models just edge the Pro on speed although it's fairly negligible.
As Clinton says, avoid the Samsung Evo drive. I wanted to buy this drive as it is a great drive - but there are many users that have had compatibility issues with it when installed in a Mac. This may rectified on a future firmware update possibly, but until it's proven I would avoid it for now.

MacBook Pro (2011) 13" keeps crashing with Yosemite 10.10.2

My MacBook Pro8,1 (early 2011) "Core i7" 13" started crashing after I upgraded and installed the free Yosemite 10.10.2 from Apple. Has anyone else with a similar model MacBook Pro laptop experienced this problem in general? Problems with Yosemite started soon after the upgrade install... the startup would get to full boot up after several restarts then crash after a time. At first I thought it was a conflict with other applications. Then after days of trouble shooting and even changing to a new Samsung EVO 250 SSD the problem still recurred repeatedly. I have re-installed the original install CD numerous times checking disk utility, partitions, etc. and got Snow Leopard 10.6.6 installed OK. Then I would update all that I could clicking updates on the Apple menu icon up till OS 10.6.8 and some other applications. Up till that things seemed to be OK. As soon as I downloaded Yosemite OS 10.10.2 and installed it...then all the crashing problems began. I could get into safe install every now again then restart only to get in a startup crash loop. I've repeatedly check my new SSD with disk utility and volumes are OK. I've run virus checks with no infection. I've run a hardware test (provided on one of the original CDs) with only good result. So I'm really baffled when my understanding is MacBook Pro of my vintage can accept OS 10.10.x as it doesn't appear to be OK on my laptop. Perhaps it clashes with my virus checker (MacKeeper) or some other application. Can anyone shed light on this problem or have a similar problem?

You probably have some software that you keep installing that is not compatible with Yosemite. The first thing you need to do is remove MacKeeper, which is a scam. See:
Ongoing MacKeeper fraud
Beyond that, it's impossible to say what might be causing the problem without more information. I would suggest downloading EtreCheck:

Run it and post the report that it generates here.

My macbook pro 2011 shows grey screen with apple logo and want start

i was just using my macbook pro and it freezed for a while not responding and i turned it off by pressing the power button. afterwards, i turn it on and it shows a grey screen with apple logo but want start pls somebody help me because am having "my life" on the machine

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 Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. 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 by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. 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.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
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 damaged 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
Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to 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.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
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 backup.
Step 8
A dead logic-board battery in a Mac Pro 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.
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.

You certainly don't have any third-party software that's causing your sluggishness.
Sometimes, a failing hard drive can cause sluggish behavior, however.
Boot into your Recovery partition (hold down the command and R keys whilst booting) and once at the Recovery screen, select Disk Utility. Select your hard drive (in your case, the aptly named "Macintosh HD") and click on the "Verify" button. If you get green text telling you that everything appears to be OK, then it's not your hard drive slowing things down. If you get red text telling you that the disk needs to be repaired, click on the "Repair" button. If the disk can be fixed, it will be. If not, call back.

How to install operating system on new hard drive without installation disc on macbook pro 2011

My macbook pro 2011 does not come with a recovery disc or any disc at all, my hard drive recently failed and i have no backup. i have replaced the hard drive but don't know how to install the operating system on the new hard drive.

If it originally shipped with 10.7 or newer, connect the computer to the Internet and start it up with the Option, Command, and R keys held down. You'll be able to install an OS.
If it shipped with 10.6.8 or earlier and wasn't upgraded to use Apple's Internet Recovery system, phone AppleCare and order the disks.

Can you start Firefox in [[Safe mode]] ?
You can also do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.
