Macbook pro (early 2011) clean install?

hey everyone, i have had a macbook for about 5 years and just recently purchased a macbook pro ... i've seen a lot of people talking about doing a clean install on their new macbook pro's ... what are the benefits of doing this? is it really necessary? what would i need to have to do it?
i'm know computers some what, so i should be able to do it, if it really does help. thanks in advance for the help!

I just did a clean install and it has fixed a lot of my problems so far...
There are times when you update from one OS to another that create new bugs due to small incompatibility problems. For example you can take a look at the problems I had: (I went from Snow Leopard to Lion)
https://discussions.apple.com/thread/3241471?tstart=30
and
https://discussions.apple.com/thread/3241648?tstart=0
To do a clean install you just need to:
>Make a full backup of your HD (Use Carbon Copy Cloner or Super Duper)
>Make sure it works!
>boot into Recovery partition
>open disk utility
>erase your HD
>exit disk utility
>start the Lion reinstall
When asked hook up your backup and let Lion copy all your information over to your new install...
> Done

  • MacBook Pro (Early 2011) No Wifi Hardware Installed

    Please help me! I'm confused.
    My 13" MacBook Pro (Early 2011) Keeps saying that No WIFI Hardware is installed.
    My Mac has been running great until earlier this week. I turned it off one night before bed and then the next morning as I switched it on, it said there was no WIFI hardware installed. I launched recover mode which is when I figured my WIFI works in recovery mode just not in the Mac itself. I reinstalled a fresh copy of OS X Yosemite which worked for a day, but sure thing the next day I loaded the Mac and then there was the same issue. So I reinstalled OS X Yosemite... AGAIN!! this time I hit an error, Yosemite had deleting my recovery drive and unmounted my Macintosh HD but thats anther story to fix another time. Once I finally repaired my disk to install Yosemite my WIFI was working again... until I restarted my Mac and it went off and the error reappeared. Luckily Apple released OS X 10.10.2 so I plugged in the ethernet and installed it which has fixed my WIFI... for now, I'm to scared to restart my Mac. Does Anyone know what is going on? Thank you
    Like I said when it gives the error (No WIFI Hardware installed) the wifi connects in recovery just not on my Mac OS. I'm currently using my Mac to submit this question and all seems fine so far.
    Thanks again.

    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilities 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.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities 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. Select Restart from the Apple menu.
    4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, 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.
    5. Reinstall Yosemite from Scratch:
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.

  • Cannot install snow leopard in macbook pro early 2011. disk is rejected. what do I do?

    Unable to install snow leopard in macbook pro early 2011. When I put in the disk, the computer does not accept it. What can I do?

    lord1908,
    some Early 2011 MacBook Pros originally came with Snow Leopard installed, and some originally came with Lion installed. If yours originally came with Snow Leopard installed, then you should be able to install Snow Leopard from its model-specific grey Mac OS X Install DVD. (The white retail Snow Leopard DVD can’t be used with it; it was made for use with earlier models, which originally came with either Tiger or Leopard installed.) If yours originally came with Lion installed, then it won’t accept any Snow Leopard DVD; instead, you’d be able to use OS X Internet Recovery to download and install its original version of Lion from Apple’s servers.

  • I have a Macbook Pro Early 2011 from the USA.  After installing Mavericks, Adobe CS6 crashes whenever it is plugged into a 27inch cinema display I purchased from the apple store in China (We moved to China). It works when not plugged into 27inch display.

    I have a Macbook Pro Early 2011 from the USA. It is now running Mavericks.  I connect it to a 27" Cinema Display that I bought in China after we moved to China.  Before I installed Mavericks, I could run all of the Adobe CS6 and Adobe CS5.5 applications on my Macbook Pro while connected to the cinema display. Now that I have Mavericks installed, whenever I am connected to my 27" CInema display my Adobe applications crash upon opening.  I know this is a rare scenario, but does anyone have any ideas how to fix this problem? Is there a new driver that needs installed?  I'd appreciate any help.

    I am also having a similar issue. I used Adobe Lightroom and my whole display goes black. Even my laptop screen and the lights on the keyboard go black. I can still hear the fan running, so I assume it is just the display. This is my first Mac and I have had nothing but issues. I think I am going back to Windows after this.

  • Cannot install lion from mac appstore. i have a macbook pro early 2011 model with 10.6.8 and i keep getting a wierd error NSInternalInconsistencyException i have no idea what to do.

    I changed my wireless broadband to a landline-base DSL wifi and it works like a charm. Sun was the culprit even you fiddle with its router and disable firewall, it won't work.
    try changing yours too and let me know how it goes.

  • Problem installing Yosemite on Macbook pro early 2011 10.7.5.

    When the installation on my Macbook Pro early 2011 OS X 10.7.5. goes to the page for installing Yosemite, nothing happens and after several minutes it says, "File system verify or repair failed" "Quit the installer to restart your compuer and try again"  I have restarted 4 times with the same result

    Ended up restoring from Time Machine.  This seemed to take care of the errors on the drive that prevented the installation.  Will try again.

  • My Macbook pro (early 2011)become very slow after maverick install

    Hi,
    My Macbook Pro (early 2011) has become very slow after installing Maverick.
    System is struggling to open any web pages, apps etc.. Even booting time is more than 5 mins. My macbook has 8 GB Ram and 750GM memory and also got 200GB of free space memory..
    Could you please advice me on this. Thanks

  • Why is my MacBook Pro (Early 2011) so slow!!!

    My Macbook Pro (Early 2011) with intel dual - core i7 4 gb RAM so slow. It came with Snow Leaopord and upgraded it to Lion, then uprgaded it to Mountain Lion. Whenever I run one of the Adobe CS5 apps it gets reeeeaaaaaaalllllllyyyy slow. It used to not get slow at all. Also when I have FCPX open it gets really slow. I used to be able to run Photoshop and Safari at the same time and now it is really slugish and slow. Is there anthing I can do to  clean it up and make t run faster?
    Thanks

    Follow Sig's suggeston in adding more RAM.
    Photoshop and FCP are RAM dependent applications.  With 4GB of RAM, open activity monitor and see your page outs and swap used. 
    I have 16GB installed - page outs - 0. swap used - 0.  see image below.
    8GB should be a perfect upgrade for what you're using it for.
    Good luck.

  • Reformatting MacBook Pro (early 2011)

    Hi guys, I need help by reformatting my MacBook Pro (early 2011)
    I want to reformat it, because the last months it became really slow. I've installed and maybe not correctly uninstalled lots of applications and stuff like this... I just wannt to clean it out, delete all whats on it.
    When i bought my MBP it came with OS X Snow Leopard and iLife 11... but NO discs. Afterwards i purchased OS X Lion in the App Store (NO disc). I've checked now on my App Store, and under purchased Apps nothing appears.
    After refomratting it, if i am not wrong, OS X SL will be installed, and iLife will be deleted.
    But I want the clean MBP with my OS X Lion and my iLife 11 on it. How do i do this? None of them are shown in my App Store under "purchased".
    Thanks in advance!
    Christian

    That is Completely incorrect. Every Mac computer that came with Snow Leopard or any other earlier version of OS X came with 2 system discs. One is the OS and the other is the iLife Appications disc. If you bought your Mac New then They Were In The Box the computer came in.
    If you don't have them, like you didn't know they were in the box and you threw that box out, you can order a replacement set from Apple.
    But if you had Lion installed then on the internal drive is the Recovery HD partition. At starup hold down the Command+r keys and that will boot you to the Recovery HD partition and from there you can Erase the Macintosh HD partition and Re-Install Lion. you will need the Apple ID and password that was used to buy Lion originally. It will ask for both of those to start the download of Lion.

    Thanks for the fast reply.
    Since the 2011 Apple doesn't send any dsiks by purchasing a MBP, so I don't have any iLife disk. So theres no other way to stay with my old iLife apps?
    The thing with lion, you say, I can see in Recovery HD if it would reinstall 10.7 before starting or earasing anything?

  • 13" MacBook Pro (Early 2011) doesn't detect display over mini DisplayPort HDMI adapter in Mountain Lion 10.8.2

    Hi to all.
    I have a problem connecting external display (Dell U2311H) to my 13" MacBook Pro (Early 2011).
    I use Tecklink Mini DasplayPort to HDMI adapter (http://www.techlink.uk.com/products/wires_cables/wiresmedia/wiresmedia_media/wir esmedia_mini_displayport_plug_to_hdmi_plug), but since U2311H doesn't have HDMI input, I also use Manhattan DisplayPort to HDMI Adapter (http://www.manhattan-products.com/en-US/products/8101-displayport-adapter).
    And nothing.
    The display is not detected, no picture or even external monitor presence at all.
    I even reset PRAM, and installed 10.8.2 Supplementary update.
    I also plugged and unplugged all I could, with no luck.
    As I can see on Apple discussion, it is a common problem with 2011 MacBook Pro's.
    It seems like the problem is in Thundebolt port, it somehow does not work properly.
    If anyone has solved such ploblem, please let me know.

    In reply to my own post have to say appologies to Apple whose Thunderbold port I used to blame.
    Shame on me)
    So, what was my problem?
    Guess what?
    Manhattan DisplayPort to HDMI Adapter !
    The point is it's actually do only what it said to do, converts DP to HDMI.
    But I for some reason thought it can be used vice versa, to be HDMI to DP converter))
    I was wrong.
    I bought new one HDMI to DVI adapter and now I HAVE external display!
    Thunderbolt works like a charm.
    So I'm very satisfied now.

  • I have a number of cds that have bonus videos attached on an audio cd.  How do i play these videos on my Macbook pro, early 2011.

    Hi:
    I have a number of newer and older music cds that came with bonus dvds attached to the audio cd.  How do i get the video to play on my macbook pro (early 2011) w/ Mountain Lion? 
    Thanks!

    Quicktime comes pre-installed on all Macs.  Quicktime 10 should be on your Dock and the original application inside your Application folder.  Quicktime 7 is inside your Utility folder.  VLC is the application that you need to download. 

  • Thunderbolt 2 external hard drive not working with Macbook Pro (early 2011)

    Hi,
    I'm new to this forum and I hope you guys can help me with this:
    I've recently bought an external hard drive that works on Thunderbolt 2 (LaCie d2 3TB). When I connect the new drive to my Macbook Pro through the thunderbolt port, the drive isn't recognized. However, the drive works fine through a USB connection.
    I thought that Thunderbolt and Thunderbolt 2 are compatible, however this doesn't seem to be the case. Maybe it's because the OS X / driver / firmware version that I'm working on that is not updated? I work on an early 2011 Macbook Pro: OS X Version 10.6.8 (Snow Leopard).
    Thank you very much for your help!
    Daniel

    Hi danielsh6,
    I recently bought the new Lacie Thunderbolt 2 D2 3TB and I had the same problem as you, i have a macbook pro early 2011, those support thunderbolt but many times there is a bug that doesn't let you connect any thunderbolt drives to your computer. The solution I found was installing this update:
    Thunderbolt Firmware Update v1.0
    Before doing this I would recommend you updating to mountain lion (not yosemite yet as there is still some glitches and more on preview's macbook pro's).
    Hope this helped!
