Won't reinstall osx

I have a MacBook black 2.17 ghz with a gig of ram, tryed turn it on and all i got was a blank grey screen, replaced hd and it says "no bootable device found- Insert boot disk and press any key" I inserted 10.6 DVD and press a key and get no response from the machine, drive spools up but screen doesn't change. Help please

You need to hit the "C" Key while turning on your machine until it registers the CD, if you look in your manual it runs you through the steps, once it loads you just need to follow your manual for formatting and reinstallation to the drive

Imac won't reinstall osx. It says my apple id hasn't purchased lion

Hi, i recently decided to give my dad my imac (2011). So before i handed it over i cleared everything from the mac so it would be back to factory settings. All hat went fine. I then went to reinstall my operating system. Everything goes well until it asks me to enter an apple id. I enter mine and a message come up saying "this apple id has not purchased lion" as far as i am aware lion came with the mac when i bought it.
Thanks.

The way i see it the only problem seems to be that i haven't purchased lion with my account. Is this the case?
Yes. Any 2011 iMac that did not have Lion already installed shipped with its predecessor Snow Leopard, and included system and applications restore discs.
If your Mac did not ship with Lion already installed, there is no need to purchase it since you can upgrade directly from Snow Leopard to Mavericks. Upgrading to Lion or Mountain Lion are options as well, but they are not free.
Boot from its original grey System Install DVD. Install that OS, install all applicable Software Updates from Apple, then upgrade to Mavericks by downloading it from the App Store. Follow these instructions: Mac OS X v10.6 Snow Leopard: How to Erase and Install

Macbook won't reinstall OSX

I have a macbook that was purchased 6 months ago and I wanted to format and reinstall Snow Leopard with the original setup disks. I inserted the disk in while the computer was booted and it told me to restart. When I restart, the apple chime sounds but the screen stays white. No apple or wait icon. I hear the CD drive running but nothing else. Help!

Try this Resetting your Mac's PRAM and NVRAM and Intel-based Macs: Resetting the System Management Controller (SMC).
If that doesn't help try holding down the OPTION key when it is starting. This will force a boot from screen to show up. Hopefully this helps.

Erased mac book pro (2009), how can i reinstall osx? it won't recognize any old system disc

erased mac book pro (2009), how can i reinstall osx? it won't recognize old system discs

Did you try:
Install or Reinstall Mavericks or Mountain Lion 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.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
            because it is three times faster than wireless.
If you don't have the original discs that came with the computer, then you can install the retail version of 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 Mavericks 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.

My 2009 MacBook Pro keeps restarting even after I wiped the hard drive and reinstalled OSX.

About a month ago, my laptop started to randomly turn off: I would be using either Chrome, Photoshop (the free CS2 version available from Adobe's website) or Powerpoint, and the screen would go blank. I would then have to hold the power button for a while until the little light at the front of the computer would flicker and it would restart. I brought it to the Mac Store where they tested it and said it looked fine. They suggested I erase my hard drive and reinstall OSX as a precaution.
Fast forward a month, I have been very busy with work and hadn't been able to fix this problem. It wasn't that bad, only once every couple of days, sometimes more, sometimes less, I could work despite this problem.
Then, I installed OSX Mavericks. The installation started in the morning, but, like an idiot, I paused it to go to work. Later on, I completed the installation, it looked fine, but then all day long my laptop would suddenly restart and go to a grey screen that said in multiple languages "Your laptop restarted because of a problem, press any button to continue the restart." A computer technician friend of mine checked it out and said it was probably due to the badly installed OSX and suggested that I erase my hard drive and reinstall OSX.
I backed up all my files, erased the hard drive and reinstalled OSX. Everything looked fine.
Then it happened again.
Any ideas of why this is happening?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login 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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

How do I connect to my external hard drive after reinstalling OSX?

I just reinstalled OSX 10.5, then upgraded to 10.5.8 on my Powerbook. Both my external hard drive and iDisk are locked, and won't let me open them. I went to information for each disk, authenticated, but it won't let me change permissions for either disk. Help!
- ®aymond

Tom,
Thank you for your advice. I did that for the external hard drive, but it still won't let me open the drive. I'm stuck because my iTunes and iPhoto libraries as well as Time Machine all are on the external. It also won't let me open my iDisk.
Tks!

Help/Question with Reinstall OSX 10.2.1 on iBook G4

First off...I just want to say that if someone can take the time to assist me I would appreciate it more than you know! Now...on to my issue:
History:
I have a iBook G4 running, I think on either 10.3 or 10.4 (I can't tell you now because it won't start up). I have the discs for 10.2.1 that came with the computer. I purchased my iBook from a roommate of mine a few years back and before selling it to me he loading 10.3 or 10.4, and I don't have those discs.
I was having an issue at start up...It would load to the point where I could see the picture I had on my desktop, and the dock would come up. Then it would stop and none of the icons on my desktop would show and neither would the menu bar at the top of the screen. When I clicked on an application in the dock, it would not load...the computer was trying (you could hear it) but it never would load it.
So, I did some online searching (using my wife's MacBook...yes, I wish we had two) and used the disk utility to verify my disc. It said the "keys were out of order". So, I clicked repair, and it said that it repaired "Book B" (at least I think that's what it said).
So, I restarted my computer, and now it comes to the gray screen with the clear spinning thing as though it is about to load. It sits there a while, and then just shuts off. So, I tried to reset the PRAM and that didn't do anything either.
Problem I now have:
I am now to the point that I am thinking I need to reinstall OSX...as said, I have the 10.2.1 discs that came with it upon purchase, but I know my roommate upgraded me to a newer version. I have lots of documents on here that I don't want to lose (and programs I don't have the discs for) and I plan to choose the "Archive and Install" and "Preserve User and Network Settings" Options.
Questions:
Is this what I should do?
and if so...
Will installing an older version than what I currently have any negative impact on the install or in me keeping my current documents and programs?

DiskWarrior is the only application that "can" fix this problem, but there is no 100% guarantee. You need to get the DW CD & boot from the CD to fix the problem.
Look at these links about DW.

http://www.jimarnold.org/blog/2008/10/keys-out-of-order-on-macbook-diskwarrior-t o-the-rescue/
I assume you don't have a backup of your hard drive, or you could just erase the hard drive & copy the backup files to it. Your next investment should be to buy & use an external hard drive for backup. You can get one for about the price + of DW.
 Cheers, Tom

MAJOR HD PROBLEMS..disc cant be deactivated, trying to reformat and reinstall osx

As the title mentions, I cant seem to partition my HD in order to properly reformat and then reinstall osx..
I basically want a fresh new factory macbook with the original lion osx (dec 2011 macbook)..
Reasons why its not working out:
Macbook when turned on goes automatically in the options menu with reinstall os, DU, seek help online and set back a time machine backup (dont have)..
Already erased my hitachi 500 gb HD and the Macintosh HD partition a couple of times (on fastest way setting, and once in the 3 times overwrite setting which took 4 hours, not tried the safest 7 times overwrite way..)
Did a control disk with DU sometimes its fine and sometimes an error pops up saying it cant be fixed.
After trying to reinstall an os mavericks in this case, after 4 hours or 3andahalf it restarts itself in the same options menu (DU, reinstall, seek online help, time machine)..
Partitioning again wont work because the disk cant be deactivated. .
What to do guys? ?

In order to repartition the drive, you can't be using it as any kind of boot drive. That includes Recovery Mode since that is a hidden partition on the drive. So the OS won't let you remove the drive its currently started up to out from under yourself.
Restart in Internet Recovery Mode by holding down Command+Option+R so the Mac is running from the firmware. You'll get what looks like the same work screen as the regular Recovery Mode, but you'll be able to repartition and completely wipe the drive. Then install OS X. The version of OS X the Mac shipped with will be installed.
Do not upgrade it to any version of OS X past that, or the new owner will not be able to reinstall any upgrade since it would require your App Store ID and password to do so.
Already erased my hitachi 500 gb HD and the Macintosh HD partition a couple of times (on fastest way setting, and once in the 3 times overwrite setting which took 4 hours, not tried the safest 7 times overwrite way..)
For future reference, unless you're trying to protect classified government documents, or other highly sensitive data, there's no reason to do any more than a one pass erase. It takes expensive, specialized hardware and software to have even a slight chance of recovering data that has been written over even just once. There's no software consumers can buy that will recover anything from such a drive.

How backup User and reinstall osx only

My MacBook Pro (06 / 2009) running OSX 10.9 Mavericks didnt want to open completly this morning. 6 hrs later i havnt fix it. Reading and trying.
-- How to make a backup now ?
I want to save some création of mine. Last backup was 1 Month old on timemachine on external USB drive.
-- How to reinstall OSX without deleting my User files and maybe my applications Adobe ?
I have Osx 10.9 Mavericks on machine from free Apple update download. But computer came with 10.5.7 when order from Apple. Also bought 10.6 Snow Léopard on CD.
-- What i have done so far
Reboot. Reset. Pram. Safe mode.
Single user #reboot
Single user # /sbin/fsck -FN
Restart from installation CD to disk utility to verify disk
Results : nothing
Disk0s2: i/o error
Invalid sibling link. The volume needs to ne repaired.

I suspect it's a bad idea to boot from your Snow Léopard disk (even with the accent) to try to repair Mavericks.
You could see if your hard drive will mount on another Mac in Target mode: How to use and troubleshoot FireWire target disk mode , then you could backup your créations.
I would not backup anything more than your essential documents. If you restore system files, you will probably restore the problem.
If you haven't already: Boot into your recovery partition (restart, hold down ⌘R until you see the Apple logo), and use Disk Utility to repair your hard drive. Repair permissions too while you're there. OS X: About OS X Recovery
then restart.
if that doesn't work, you could try the recovery partition again and reinstall Mavericks over your current installation.
If you can't boot into your recovery partition, then try to boot into internet recovery: Hands on with Mountain Lion's OS X Recovery and Internet Recovery | Macworld , and use Disk Utility to repair your HD. similarly, if that doesn't work, you could try to erase your HD from internet recovery and reinstall Mavericks.
if that won't work, you could try TechTool, which can occasionally fix a problem that Disk Utility can't. Techtool Pro 7
if that doesn't work, then your HD is probably failing and needs to be replaced.

If I reinstall OSX will I lose my apps?

I want to reinstall OSX - Finished a year at uni and have a load of stuff I don't need. Just want to wipe and reinstall so it's fresh again. Problem is I have a couple of apps I downloaded from app store (cheap ones like angry birds), but couple of more expensive ones like Call Of Duty. Will I lose all these? Is there anyway of backing them up to re-install?
Thanks, Christian.

First, unless you have a good reason - and just having "a load of stuff" is not a good reason - a clean reinstall of the OS is extreme on a Mac. It should only be necessary for very severe problems.
Second, if you wipe the hard drive, then everything not backed up will be lost, of course. However, note that you can re-download apps purchased through the Mac App Store, so they won't be truly gone.
As for backups, see my Mac Backup Guide.

Reinstalling osx over a linux install?

Hi,
I've got a mini with ReiserFS on it, running Debian. I want to reinstall osx over it, but the OSX install disk won't see the drive.
suggestions?
Thanks.

wow, I can't believe I didn't think to do that. Worked like a charm.
This is why I don't do 20 hour days any more. That should have been obvious
Thanks =)

Ilife will not install after reinstalling osx

Hello,
I've had a few troubles with my macbook air 10.6.5 - and I was told it's probably a software thing, so I should reinstall osx, which i did. But when I try to install Ilife 11 from the usb pin that came with the computer, It keeps telling me that an unknown failure has accured and i can't install.
any ideas?
- Elias

Don't think this is quite answered yet. I just bought iLife 11 for my up-to-date system (24" iMac) and iLife wouldn't install outta the box. I found this thread and successfully installed iPhoto separately. After that, I ran the custom install again, deselecting iPhoto this time, and tried to install the rest. It failed again. I tried the good 'ol process of elimination and installed iMovie by itself with no issues. iDVD install failed but GarageBand and iWeb installs worked fine. This is very un-Apple and I'm disappointed. Good thing iDVD (or iWeb for that matter) wasn't updated in this release, otherwise this would be a bigger deal.
To recap, I installed each of the following apps, separately, in this order: iPhoto, iMovie, GarageBand, iWeb. iDVD won't install. Hope this helps someone else.

Only the recovery disk shows up when trying to reinstall OSX.

I was trying to erase and install OSX because my computer was starting to get really slow. It actually froze on start up, disk utility was the only way I could get it to work. I erased everything off my "Mac HD" disk i believe that is what it was called, whatever the default was. When I reinstalled OSX it finished everything but froze as soon as it started to boot up the desktop. From there I had to go back into disk utility and check everything. It appears there is nothing on my, used to Mac HD drive, which is now renamed. Where it shows "Available space" it only shows a "-". When i try to verify and repair this disk it says that journal need be replayed, but volume is read only, or something like that. I tried resetting the PRAM already and it does nothing. I have successfully reinstalled OSX a few weeks/months ago due to similar slow computer performance, but this problem came up this time. What did I do to mess this up so badly?

caroliver,
you didn’t necessarily do anything to mess it up; hard disks are mechanical devices, and they won’t last forever.
Are you still able to boot into Recovery mode? If so, do so, then select Utilities from the menu bar, and run Terminal there. Give the following commands in the Terminal window:
diskutil list
diskutil cs list
mount
Please include in your reply the full output from these commands.

I just bought a used computer with OSX 10.8 and want to reinstall OSX 10.6.3 Snow Leopard . . . How can I do this?

First off you need to know the model identifier of the machine, not all Mac's can be reverted to Snow Leopard and not all Mac's can use the 10.6.3 Retail disk!
To find the model identifier, boot the machine up and hold the command key and the spacebar, Spotlight appears at the top right corner and type in System Profiler and press Enter/Return.
The model identifier should be something like "MacBook Pro 9,2" or something of that nature.
You also can hold D while the computer is booting on/near a Internet connection for a long time and this loads Hardware Test, which one of the panes will give the required information.
Next you download MacTracker here and look up your machine and it's original operating system.
(Don't click the AppStore version obviously)
http://mactracker.ca/
You may have to right or control click on the program to bypass Apple's Gatekeeper and run the program.
If you have the model identifier and the machine won't boot, then just ask here and we can tell you the information
Now all Intel Mac's issued before July 2011 can install Snow Leopard, but the Mac's released after July 2011 came with OS X 10.7 Lion and the firmware won't boot off the Snow Leopard disk. (however 10.6 can be shoehorned on using Firewire Target Disk Mode and another Mac for some models after July 2011)
Also the 10.6.3 Snow Leopard Retail Disk sold at Apple only works on Mac's that came with 10.4-10.6.2 from the factory.
Any Mac's that originally came with 10.6.3-10.6.8 from the factory need model specific disks from Apple directly, not sold at their online store, you will have to call them with your Mac's serial number and order these disks.
If you get the right disk and have the right machine, then you should be able to insert the disk and hold c down or the option/alt key and boot from the 10.6 disk.
Follow these directions and make sure to erase the ENTIRE DRIVE first in Disk Utility or you will have issues later trying to fix it from the disk.
