How do I reinstall the operating system on my MacBook Pro without using my apple id?

I'm selling my computer. Everything has been erased. Now the operating system, Lion, needs to be installed. I believe the computer did not come with a cd so reinstalling is done through wifi.

We bought it in January 2010. I'm not sure what OS it came with but when I look at the dates of each OS on wikipedia it looks like it came with Snow Leopard. The only disk I happen to have is Leopard.
Let's drop back a minute and go through what you can and cannot do with this machine.
1. If the machine came with Leopard, you can install Leopard and then go to Snow Leopard and up the line of the on-line Mac OS X versions, that is, Lion, and Mountain Lion and Mavericks as compatible. If the disk for Leopard that you have is a grey face disk, that is a machine-specific disk and will only work if it is the disk that came with your MacBook Pro. If it is a panted face (black) with a large silver X it is a retail version and will install IF your machine came with Leopard.
2. If your MacBook Pro came with Snow Leopard, it will not install Leopard. If it came with Snow Leopard and is a 2010 machine, it will not install the retail version of Snow Leopard since that is 10.6.3 and the 2010 and later machines came with 10.6.6 preinstalled. You must call Apple Customer Support and have them send you the machine-specific install disk for that machine. There is a fee of something like $20 in the US for doing that.
3. If your machine came with Snow Leopard, you need to reinstall Snow Leopard and then move to the on-line Mac OS X versions, you cannot download a version with your Apple ID associated with the version currently on the machine. The starting point HAS to be Snow Leopard for the new owner to do an on-line Mac OS X download.
4. With Snow Leopard installed and on-line software updated to 10.6.8, the new owner can then move up to Lion or above depending on the compatibility of the hardware. To move to Lion or above the machine must have an Intel Core 2 Duo processor. To move to Mountain Lion or Mavericks the machine must meet the requirements in http://support.apple.com/kb/HT5842.
At any rate, the new owner must install Snow Leopard on that machine before any move to one of the Mac App Store versions of Mac OS X.

What is the operating system on my MacBook Pro

I am trying to find out whether I have Lion, Tiger. Leopard etc on my MacBook. My Mail is configured to appear on my Blackberry phone, which is fine but if I compose an e-mail in Mail on my Macbook it appears several time (up to 50) on my Blackberry which I then have to laboriously have to delete. My internet provider have asked me to identify what my operating system is but all I can find out is that it is Mac OSX Version 10.6.7. If anyone has any idea how to rectify this problem it would be helpful as well.
Many thanks

Hi Linc, many thanks for your reply, my internet provider told me that there have been a few problems with the new operating system Lion, but I don't have that, they also said that if I hadn't got Lion then I would have to remove the account from my MacBook and set it up again. When I first got my MacBook a few months ago it did it all for me. They have given me instructions on how to do this so fingers crossed!!

HT1338 How do I update the Operating System for my MacBook Pro?

I currently have OS version 10.5.8. I can't get the proper plug-ins for Flash anymore because my Mac OS is too old. I've tried updating the OS, but it will not let me install it. Any help on this would be greatly appreciated. Thanks.

Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) — Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) —
             Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) — Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) — Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) — Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) — Model Identifier 3,1 or later
         7. Xserve (Early 2009) — Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Are my applications compatible?
         See App Compatibility Table — RoaringApps.

So I do.

I want to install a third operating system on my macbook pro. I already have windows and i want install unix or linux in there. Is it possible??

I want to install a third operating system on my macbook pro. I already have windows and i want install unix or linux in there. Is it possible??

Yes, it's possible, but if your Windows system is on a Boot Camp partition then you have to first remove it. Then create however many partitions you want for the operating systems. You have OS X on one, so you need two more - one for Windows and one for Linux. You then install Windows and Linux separately to their respective partitions. Download rEFIt
Use it as the replacement bootloader so you can properly boot from each OS properly.

I have iWork 09 with a family license. I am unable to install the software on my new Macbook Pro (the message is simply "Installation failed"). I wonder if I need to remove an old computer from the family license, and if so, how?

I have iWork 09 with a family license. I am unable to install the software on my new Macbook Pro (the message is simply "Installation failed"). I wonder if I need to remove an old computer from the family license, and if so, how?

Yes, gladly. I am trying to install on a 13" MacBook Pro with OS X 10.8.3. I insert the disk into the SuperDrive. The I work '09 window pops up with two icons: one Tim install and one that says "Read before you install iWork." I double-click on the "Install iWork '09" icon, and a window appears that says, "This package will run a program to determine if the software can be installed." I click "continue" and see "Welcome to the iWork '09 installer." I click on "Continue." The "read me" bullet on the left lights up, and I see "Read before you install. . . ." I click "Continue," then see the software license agreement. When I click on "Continue" again, I am asked to agree, and I do. The window then says, "Standard Install on 'Mackintosh HD" and indicates how much space the program will take.
I click "Install," enter my password, and the installation begins. It goes through a validating phase and begins "writing files." It indicates that installation will take about 30 minutes (although that number fluctuates). After about four minutes it goes to "cleaning up." Then after just a few seconds, the "Summary" bullet on the left lights up and this message appears: "There were errors with the installation. You may want to try installing again." There is a large yellow triangle with an exclamation point in it, and a bold "The installation failed." Below that appears "The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance."
At that point, a "Close" button is pulsating blue at the bottom of the window.
Sorry for the tedious detail. Anything revealing there?
Thanks!

How do I disactivate the operating system on my macbook that was stolen from me?

So in early September someone who I know broke into my apartment and stole my computer, I called the police and filed a report. I have some very snesitive documents on the computer that I would prefer no one to get their hands on. I was able to find the operating system disk I had purchsed to update the operating system a few years ago so I have all of the information associated with the OS. I do not know the IP address of the computer or exactly where it is (obviously or I would have it back). I want to basically turn the OS off so my files on the computer cannot be opened or used. Is there any way to disactivate the OS remotely like you can with Windows (if you use the product key on another PC it deactivates the previous version). I don't know if it matters but it was a late 2006 macbook (black) model 13" screen.

HT1338 attempting to update operating system software on Macbook Pro with OSX 10.4.11 what is the cost and how

attempting to update operating system on macbook pro with osx10.4.11.
how is this accomplished and what is the cost ? is the worth the expense give the age of unit?

Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
OS 10.6 Snow Leopard is once again available from the Apple Store:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and in the UK:
http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
but nobody knows for how long it will be available.
To use iCloud you have to upgrade at least to Lion, but some functions are only available in Mountain Lion:
http://support.apple.com/kb/HT4759
You can also purchase the code to use to download Lion (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:

When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.

I have a MacBook Pro and a Canon MX452. I updated the operating system on my MacBook to Yosemite 10.

I own a Canon MX452 and a MacBook Pro (2010 model). This week I updated the MacBook operating system to Yosemite 10.10.3. Afterwards I found the printer / scanner functions would not work. I re-loaded the CD from the printer and was also prompted to download more currrent drivers from the Canon website, from which I chose the ICA Driver V4.0.0 and the Canon IJ Network Tool V4.5.0 (not sure if these were the right ones or not).
I managed to only get the printer working when using the USB cable to the printer. I could not get the printer and scanner working wirelessly. The printer blue light shows it is connected to my network ok. I also noted my iPad and iPhone can no longer "see" the printer either.
I have deleted and re-loaded the Canon software several times. I have followed Canon instructions to:
-Connect the MacBook to the router with an ethernet cable and go through the instructions to "connect" the Canon MX452. But afterwards, the MacBook says the Canon MX452 is "off line" and I can only make it work with the USB connection.
Any guidance would me most appreciated to:
-get the printer and scanner working wirelessly
-getting the Air-Print feature working with the iPad and iPhone
Thanks
Stephen
Solved!
Go to Solution.

Hi John. Thanks for that input. At Step 6, after clicking "Next" I get a window telling me my OS version is unsupported and the installation may not complete. I am prompted to go to Canon's web site to "Check Latest Info".
I've had this window on previous attempts and from Canon's web site I downloaded two drivers as follows
- ICA Driver V4.0.0
- Canon IJ Network Tool V4.5.0
I'm not sure if these are the correct / complete drivers I need for this install or not.
I continue to follow all the steps. At step 9 I click "Wireless Set Up using USB" amd get a License Agreement (a little different than instructions)
I click "Agree" and it goes to a Setup window with two progress bars showing the installation. I've not been prompted to connect the USB?
After the Setup window is done, I am then prompted to connect the printer via USB. I connect the printer and click on "Redetect". It is not detected.
I then try following the Canon on screen instructions for connecting to the wireless LAN amd enter the password. It searches and indicates "Connecting" on the window, but it never connects and the blue light just blinks
So, at this point I am stuck??
Thanks

The current operating system on my MacBook Pro is 10.5.8. I would like to upgrade it so I can use iCloud. Which newer version of OS should I download?

Would like to use iCloud, but am currently using OS 10.5.8 with my MacBook Pro. Which newer OS should I download?

Yes.
Get the Snow Leopard install DVD (Amazon etc...)
Use software update to get Snow Leopard 10.6.8
In Snow Leopard, you will have App Store application under the Applications folder
Launch the App Store app - it will use your Apple ID to set up purchases and payments
Search for OS X Lion
Purchase Lion - it will download and install automatically over Snow Leopard
NOTE 1:
Make sure you backup whatever is necessary. That should go without saying.
NOTE 2:
Your Mac will likely be able to run Mountain LIon which is coming out in a couple of weeks.
I think, if you buy hte Lion now, you might be eligible for free upgrade to Mountain Lion.
If not, I'd hang on until ML is out, then buy it - that would be my preferred solution
Here is some info on upgrading and eligibility...

How do i install a free osx or operating system on my macbook pro 2008?

Hey so the go is i have a macbook pro 2008 i love it too bits but for some reason my screen flickers all the time but ill just have to deal with it. Secondly i cant install any operating systems because i dont have a mac to download osx from or mountain lion. And when i go to download it directly from my macbook pro it says i need to buy it :/ or i dont have the licence i cant remember but i just want it working whoever can help me i would much appreciate!! thankyou for reading this and also ps my screen when im on the net on it in the safari osx menu it intermittly spazzes and all the url bars keep clicking etc i dont know what the problem is but i would appreciate some advice or help! it is a good machiene quiet no damage looked after just got it given to me from a family member but i have had no luck so far

Jamesandmacbooks,
if by “free” you mean “gratis” (as opposed to, say, “open source”), then there’s only one version of OS X to date that’s gratis, namely Mavericks. You can only download Mavericks if you currently have Mac OS X 10.6.6 or later installed. If you’re still running Leopard (Mac OS X 10.5.something) on your 2008 MacBook Pro, then you’ll need to first purchase the white retail Snow Leopard DVD, install it on your MacBook Pro, and run Software Update to get it to 10.6.8, after which you can download Mavericks gratis from the Mac App Store and install that. Be sure that your MacBook Pro meets all of Mavericks’ system requirements before trying to install it. If you currently run any PowerPC apps, note that they won’t be supported in any version of OS X after Snow Leopard.

HT1338 what is the idle system preference for macbook pro

I want to know the best system prefrence set up for Mac pro. I upgraded to lion and ever since my chat gets disabled sunddenly and I cannot type anymore

There is no "best" system preference set up.
If you have problems with Lion try this first:
Repair the Hard Drive and Permissions - Lion/Mountain Lion
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
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 then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
If iChat is the only application with which you have a problem, then try deleting the /Home/Library/Preferences/com.apple.ichat.com preference file in case it's corrupted.
If this doesn't seem to help then you might try reinstalling Lion:
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.
