Reinstall MAC OSX

Can I reinstall my OS w/o format my HD?

Possibly by doing an Archive and Install:
How to Perform an Archive and Install
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) 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 quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Problem reinstalling Mac OSX 10.5

I am having a problem with reinstalling Mac OSX 10.5 after putting in the disc to do it everything was fine it asks what language I want and then it tells me that it can not be installed on this computer. I am trying to install it on a MacBook bought last year it is an intel machine and I have always kept up on the system updates. I don't want to take it in to a store more because I am stationed in Japan and getting it to a store requires more work than it is worth. If there is any advice on what to do I would greatly appreciate it.

You need the original grey system discs for each Mac model you own, not just to be able to reinstall the OS but also to reinstall the model's bundled retail application software (like iLife, if included) & to run the very model-specific Apple Hardware Test it contains if that is ever required.
The retail Leopard discs do not include either of these capabilities, so unless you are desperate to get Leopard reinstalled on the MacBook, you should try hard to find the original MacBook system discs. Failing that, you can contact AppleCare & request a replacement disc set. Generally speaking, Apple will ship one to you for a nominal replacement cost if you can show that you own that model by providing its serial number or other proof of purchase information.
Regarding installing Vista or Windows XP, both the retail Leopard & system discs include Boot Camp, which includes a convenient utility to format the hard disk for dual booting. While complicated, this can be done without that utility but you still need the hardware drivers the disc contains to get the full use of the Mac's hardware when running Windows. I have no idea if say an iMac's system discs have the Windows hardware drivers that also support a MacBook or if this too is model-specific, so on that you are on your own.

Guitar21,
your MacBook Pro has booted into its Recovery mode. From the OS X Utilities menu, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Does it get to the login screen now?

I am trying to reinstall Mac OSX, but my computer does not read installation cd

Hello, I am trying to reinstall Mac OSX, but my computer does not read installation cd. After restart, I hold C but either eject cd or doesn't read and computer boots up normally. I even ordered a new pack of installation cd, but still the same problem. Is there anybody can help me fixing this issue, because my Macbook pro has lots of software problem and when I spoke to tech, they said it needs to reformat and reinstall the OSX to solve all my problems. Please help me to reinstall my OSX!

Possible solutions:
You need to hold the c key down before booting
You need to use the built in keyboard, you have other hardware connected
You need the machine specific 10.6.4+ disks for that machine, the retail 10.6.3 disks won't work
There is a firmware password on the machine preventing the at boot key command functions
Try the option key for Startup Manager to boot from the disk, right after the "bong"
Your Superdrive lense is dirty or not operating, other hardware issues
You have malware of some sort

How do I reinstall mac OSX 10.6.4?

how do I reinstall mac OSX 10.6.4?

Reinstall 10.6.4? exactly?
Only if you have 10.6.4 on machine specific disks that came with your computer (or you can call Apple for the disks)
However if you Software Update, Apple will bring your machine up to 10.6.8 automatically, with all the security and bug fixes. No choice to stop at 10.6.4 exactly.
10.6 is the Snow Leoaprd operating system, 10.6.3 or 10.6.4 or 10.6.8 is the updates to 10.6 that also occur when you run Software Update under the Apple menu.
So if your machine originally came with 10.5.x something and you upgraded via the 10.6.3 white retail disk, if you Software Update, you can't get to 10.6.4, it will just bring you to 10.6.8.
So if you want to reinstall 10.6.4 specifically, it would have to be the machine specific disks if your Mac orignally came with 10.6.4, else you will be force upgraded to 10.6.8 from any 10.6 version.
Now there are two ways to resinstall OS X, one way is to write say 10.6.8 over with 10.6.3 or 10.6.4 via the disks, and only 10.6 is overwritten, not your third party programs (most) and not your files. However you will need to Software Update, because your Apple related support files have been changed.
See #8 Reinstall Just OS X for that then Software Update to 10.6.8
Step by Step to fix your Mac
Another method is to wipe the entire drive or boot partition, then install 10.6 from the disk, then you don't have too Software update to 10.6.8 to get all the bug/security fixes if you don't want too.
I don't know what you want exactly, but I'll give you the links.

Reconnect Magic Mouse/keyboard after reinstalling Mac OSX

After about a week I finally managed to reinstall Mac OSX Snow Leopard...I took a RAM stick out at random and it worked...good thing there weren't any Genius bar appointments which suited me.
Anyway, now I need to connect a keyboard
I've already got my USB keyboard in it (The same size one as the wireless one...but this one's wired)
I've unplugged it, plugged it back in. I've dug out my wireless keyboard and nothing's happened (Yes, the green light blinks...)
I put my iMac to sleep, I turned it off, it still isn't working...
I could try and find a wired mouse/keyboard somewhere...but I can't believe my wired Apple keyboard isn't working with it ^_^
I'm surprised Apple think this wireless stuff is a good thing...I'm more surprised my wired keyboard won't connect...
It's an iMac 11,2 (I think - Whatever the late 2010 one was) and I'm running Snow Leopard.
Also - When's it safe to put the RAM back in? Or is it actually faulty and I need to get a replacement? How can I check?

Just to clarify, this is what I want/hope to do:
Backup my iMac using Time Machine (Complete)
Format the iMac to factory settings (Complete)
Reinstall Snow Leopard (Incomplete)
Restore some files and folders (Incomplete)
Maybe upgrade to Lion...if I'm in a good mood.
I'm mainly doing this because my hard drive stopped last week, and the hard drive fan sped up. I had to restart, went into safe mode and...I don't actually know what you're supposed to do in safe mode so I restart normally. The next day, I turned my iMac on and it had that bar below the logo as if it was booting in safe mode, the bar appeared to have stopped, so I turned the iMac off, and upon turning it back on, the bar was back, so I decided to leave it and it started fine. The next day, once again, the bar was there so I left it, but once it got to the desktop, Finder wouldn't load, I tried relaunching Finder a few times, then restarted the computer, if I remember correctly, it restarted and Finder wouldn't load again. I tried again, this time it wouldn't boot at all, I Googled it a bit and tried resetting the PRAM, SMC etc., then found that you can read what's happening when it's booting to safe mode, and many errors came up saying that some numbers were incorrect, after a few minutes, it said "Halting CPU" or something, and that's when it turned off. I then booted from the disc, and restored using the Time Machine backup. I wasn't pleased with the backup; some applications failed to load properly. I thought I might as well restore it and just copy a few files across, to save space and speed up the computer.
The many times I tried reinstalling Snow Leopard, it didn't work. I tried many things, and last night I decided to make a disc image or something to a USB stick. I don't think it was an image, because the tutorial I followed which worked didn't require that you create an image. After trying to install from the USB stick, it failed, I then removed a RAM stick, it finally worked! But my keyboard wouldn't connect...that's when I came to creatin this post, and I tried reinstalling again, it failed to reinstall, I tried removing the other RAM stick, still failed.
Last week wasn't the first time my hard drive suddenly stopped, it's happened a few times before, but the hard drive fan hasn't sped up upon the hard drive stopping, and it's also managed to start again and the computer to continue working a few seconds later. Maybe it is about time I take it to Apple...but my warranty's ran out so I'm not sure if they'll help me.

My volume isn't recognized when reinstalling Mac OSX Tiger

I am reinstalling mac osx on my mac book black, because I got a folder with a question mark whenever I boot up my computer. When I'm installing the disks there's no volume to install mac osx. What do I need to do?

From the Tiger installer you need to open Disk Utility from the Utilities menu. On the left side, see whether your hard drive shows up. If it doesn't, your hard drive has likely failed and you'll need to purchase another one or take your macbook to a service provider to have it replaced.
If it shows up, you should try to repair it or reformat it, depending on whether you're worried about the data that's on it.

If you reinstall Mac OSX 10.5, does it erase all your files and settings??

If you reinstall Mac OSX 10.5, does it erase all your files and settings, if it does, how would you install iMovie by itself, because I accidenatlly deleted imovie

jd087 wrote:

that depends what reinstall option you choose. an erase and install will erase everything. an archive and install will preserve user data and applications.
However neither one will reinstall imovie which is part of ilife which is separate from the OS itself. you can reinstall ilife only. there is no need to reinstall the whole OS. if you bought ilife separately then use the ilife DVD. if ilife came with your mac then insewrt install disk 1 that came with your computer, open it in finder and double-click on "install bundled software only".

Help: Tried using disk install to erase and reinstall mac osx

Could someone please help me. I just bought a second hand macbook pro off someone and upon recieving it realised they hadn't erased everything and their user account was still set up and active as administrator. This means i'll have issues down the track doing updates etc.
I googled how to hard reset the computer to start from scratch and followed steps. Basically they were
1. Restart computer whilst holding down the command and r buttons (which I did)
2. When the wifi connection box comes up connect to reliable wifi (done)
3. Then it said go into the disk utility and erase the mac os extended disk (the problem here is 1. the steps didnt specify that it should be the macintosh HD disk erased and 2. It should be the mac os extended (journaled) version, i've just fogured this out after a lot more searching as to why the reinstall of mac OSX wouldn't then work)
now i'm freaking out that i've done irreperable damage given that the mac OSX base system (mac OS extended (non-journaled)) has been erased. Can anyone please tell me if this can be reinstalled? Or what I should do next?

...Mac OS Extended' and 'name: mac OS X Base System' both greyed out along with the erase and security options (The option to erase is unavailable, so im assuming it means the mac os extended has been erased in this partition) (capacity: 1.39GB, available: 224.7 MB, used 1.17GB)
whereas in the macintosh HD partition nothing has been greyed out (so the option to erase is there, which im assuming means it hasn't been erased)
(capacity: 319.73GB, available: 319.3 GB, used 425MB).
Does this help explain the situation?
That does help. The reason why the Macintosh HD partition is the only one where nothing is greyed out is that that's where your new OS X installation should be targeted (note that it's the only partition with room for a full OS X installation as well as your own files and applications). The option to erase is available in case you want to, for some reason, erase it again. Remember, you're booting from the Recovery HD and that's a partition on your HD too. You aren't allowed to erase the partition you booted from (hence, it's greyed out), and, since it's normally hidden, as are others, such as the EFI, it shouldn't be messed with anyway.

Unable to reinstall Mac OSX

Hi, I recently bought a preowned Macbook. I want to reinstall the operating system but when I put in the "Mac OSX Install Disc 1" and rebooting it, it said "This software cannot be installed on this computer."
Why is this? How can I get past this?
Thanks

Hi
Check that the disks are for the Macbook as grey discs are machine-specific. The seller should've given you the discs with the computer.
I presume this is an Intel machine? If so, the black DVD (silver X) won't work on it either as it is PowerPC. This message normally means you've got the wrong kind of disc.
If you have trouble locating the seller, you could try contacting Apple & explaining the situation to them. They may be willing to send you the right discs (you will probably have to supply Macbook's serial number so they give you right ones), though there will be a charge for that.

ReInstall Mac OsX Why did I get the Lemon?

Hello folks since my MBP is a lemon I need to resolve some issues again and again and some well I have never resolved like crackling audio... Maybe I expect too much from this hunk of junk, I have a large drive with 100+ programs installed 2mb of Ram and I run bootcamp. My Cpu gets maxed out when running Saffari? ***? Audio drop outs crackling, freezing you think I was running a windows machine,
crap man I really feel like suing apple and getting a new MBP this one after 3 years of problems I am convinced it has crappy hardware being the very first Gen.
Anyhow looking past my venting I am wondering this
Is there a way to reinstall the files for Mac OSX without having to redo my whole computer? U can do this on windows i know. It will take me a week to redo everything otherwise. I have never done the time machine thing either...
Any other suggestions? I need to use this computer for live audio but I can't trust it in its current state.

Time machine backup and restore from an external HDD. Or, use Archive and Install with Preserve Users and Network Settings.
Sorry for your troubles - my 1st gen MBP has worked flawlessly for over three years now, the only problem being a bad battery (Sony's fault), which Apple replaced for free several months after my warranty expired.

TS3926 Unable to reinstall Mac OSX Lion after internet recovery

Sequence of Events on My Macbook Air
1. I saw a flashing question mark in the morning on starting my macbook air
2. I then tried the internet recovery of my Macbook air
3. The system took me to a recovery partition where my only option was reinstall the OSX lion
4. I tried following the system till the Mac OSX lion disk selection
5. I do not see any disk to select and hence cannot proceed.
Any pointers? Is my hard disk gone for good?
Please advice Urgent!!!!

It's possible that the flash storage is damaged, but first, see if it's working properly. After starting in Internet Recovery, open Disk Utility and tell me if you see Macintosh HD in the sidebar. If so, go to Macintosh HD, open Erase tab and erase the disk. Finally, close Disk Utility and reinstall OS X.
If you don't see it, see if the flash storage appears at the top of the sidebar. If so, choose it, go to Erase tab and erase it. Then, reinstall OS X.
If you don't see the flash storage in Disk Utility or your Mac is in warranty, take it to an Apple Store or reseller

Cannot reinstall mac osx 10.5.6

Hey guys, I am having a problem reformatting my iMac. I am currently running 10.5.8 on my computer. I inserted the mac osx 10.5.6 install dvd and restarted my computer, holding down the c button until the install screen appeared. After choosing the language, it gave me an error saying that mac osx cannot be installed on this computer. Please help me out as I need to get this resolved ASAP. Thank you in advance!!

Yes, but keep these in mind:
-The $29 Snow Leopard upgrade box is licensed to be used only on a system that has a licensed copy of Leopard on it. So if you buy that, you'll need to buy a Leopard install DVD too to comply with the terms of the license.
-The Snow Leopard Box Set (with iLife and iWork) does not require any previous system to be installed, so you can just reformat with that and be ready to go.
-Even if you choose one of the above two options, it's still a good idea to get a copy of the original install discs, because they include a hardware check utility; and including them when you sell your Mac will help its resale value.

IPhoto Library won't load after reinstalling Mac OSX

I have reinstalled mac i was having some problems and i am a newbie in mac so i tought a clean install would be good at that point
After reinstalling i had my user folder backed up i moved the files back to their original place, and organized everything because it was messy, and then started a timemachine backup on an external drive
so in short:
i reinstalled mac
restored my iPhoto Library to the Pictures folder
Updated everything to the latest version ( since the photo library was created with the latest version )
when i tried to open iphoto it stayed reloading for an hour then i gave up and searched online
my pictures are all there i can copy them and start a new library but that is not what i want
i want my events as i sorted them i want my faces as i sorted them i spent a lot of time making these pictures as they were
please help
Things i already tried:
vacuuming the *.db sqlite files
removing the faces.db so that if the faces are the problem i would know
tried removing all *.db files
tried to import my photos to a new library but that is not what i want
right now i have 2 libraries, a new one wih ****** event names
and the old one that is corrupt

Using your original library try the following: make a temporary, duplicate copy of the library and try the three fixes below in order as needed:
Fix #1
Delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/Library/Preferences folder, launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding the the Option key. You'll also have to reset the iPhoto's various preferences.
Fix #2
Launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library.
Select the options identified in the screenshot.
Fix #3
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
