A clean install SL or Downgrade to Leopard?

Hi,
Since I've try out every single troubleshooting and c'ld not resolved the "no airport card installed" issue, I'ld like to try to clean install.
S'ld I clean install "Snow Leopard" or back to "Leopard" to test/try my luck to resolve the issue above?
Thanks for suggestion!!!

sig,
SL which made me facing the issue above!
Do you mean "Erase and Install" is the only way from MBP Installer Disk in stead of just Reinstall and remaining everything?

How to sync iPod after "clean install" of new OS Snow Leopard

I just upgraded my iMac to Snow Leopard, doing a "clean install".When trying to sync my iPod nano, 41 items couldn't be copied, as "not authorized", although all were purchased purchased from the iTunes Store. Following directions to click on "Store" in iTunes, and "Authorize this Computer", I received a message that this computer was already authorized. How do I go about getting these 41 items on my iPod?

I figured out the problem. I used a different email address when registering my Apple ID after the OS upgrade, and neglected to list other email addresses. Apple now thinks this computer is two different computers.
After signing in with the old email address and resetting the password, I am able to sync the rest of the songs onto the iPod.

Snow leopard app store not working after clean install. Anyone else having this problem?

The App store has stopped working after a clean install of OS X Snow Leopard. The get/install buttons go grey after I've clicked on them then nothing....
It doesn't hang, all the navigation buttons work fine, and I can log into iTunes fine. Just can't buy anything...

Try resetting the App Store and Clearing Cookies.

ILife gone after Leopard clean install

Hi, I just made a clean install of mac os x leopard on an old macbook pro (2004). I just realize that it comes without iLife. How can I get iLife back? I don't have the original grey install dvd's anymore. Thanks.

Your pre-bundled software is reinstalled using the Optional Install package in the same-named folder on your original installer disc. Since you don't have them you have to purchase replacements:

Can I do a Clean install on 1 drive of a 2 drive setup?

I have 2 internal drives, 1 a 300gb which is full, and a new 1tb empty.
I want to do a clean install and upgrade to Snow Leopard on drive 1.
So I've just cloned hard drive 1 onto drive 2, with the excellent CCC. So drive 2 is an exact bootable copy. Can someone please give me some advice on my next move...
Is it ok to remove internal drive 2 from the machine, so i don't accidentally erase this disk (i cannot risk any chance of losing my files) while I clean install drive 1 with an upgrade of Snow Leopard?
Can I then re-fit drive 2 and copy over my software, preferences and settings to drive 1? even though drive 2 will be 10.5.8 - Is this ok?
Will all it's contents be seen when I re-fit the drive? - or will there be an OS clash? As both drive's will contain an OS - Does the OS only run from the drive which is specified on start up?
Thanks everyone

Is it ok to remove internal drive 2 from the machine, so i don't accidentally erase this disk
Yes, but as long as you are reasonably careful to select the 1 TB drive for the Snow Leopard installation, it isn't necessary to do this. In fact, if the other drive is almost full, the installer may not let you choose it.
Can I then re-fit drive 2 and copy over my software, preferences and settings to drive 1?
If it is full, then you could not do this in the first place. In the second, some of the software installed with Snow Leopard won't be compatible with 10.5. IOW, don't do it.
Will all it's contents be seen when I re-fit the drive?
Yes. Each drive will appear separately. If you give them different names there will be no confusion about which is which.
or will there be an OS clash?
No.
Does the OS only run from the drive which is specified on start up?
Yes.

Clean install with 29$ single?

Can the 29$ box do a completely clean install with just the snow leopard disk? I currently have Leopard installed to the latest updates and XP on a BC partition.

Thanks, but I have no problem booting the DVD that came with the box. Only the upgrade DVD.
I called the Apple store and they told me to return the product. That might also explain why the upgrade process went so quick (17 minutes) but utterly painful afterwards with dozens of kernel panics).

G5 with leopard 10.5.8 running slowly, attempting to clean install but only have original 10.4.2 discs

My dad has an iMac G5 1.9GHz running 10.5.8 with 2.5GB ram which is running extremely slowly. I want to back up the hard drive and then do a 'clean install' to attempt to fix the issues. However, he only has the original discs for 10.4.2, having upgraded to leopard using my brother-in-law's family upgrade disc.
My question is, if I erase the hard-drive and then install Tiger, will I be able to use Timemachine to access his backups, as they were done using 10.5.8?
And if my brother-in-law no longer has his Leopard upgrade discs will I be able to get a copy?
I don't want to downgrade the machine if there's no way of getting it back up to 10.5.8
Many thanks in advance

Before you erase the drive see the following:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard. These utilities have limited or no functionality with Snow Leopard and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc. Other utilities are also available such as Onyx, Leopard Cache Cleaner, CockTail, and Xupport, for example.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Backuplist
Carbon Copy Cloner
Data Backup
Deja Vu
iBackup
JaBack
Silver Keeper
MimMac
Retrospect
Super Flexible File Synchronizer
SuperDuper!
Synchronize Pro! X
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup

How many times can you clean install leopard on the same computer?

How many times can you clean install leopard on the same computer? Will the leopard dvd run out of installations and not let you install anymore?

Hi colman Prez;
Now that the funny comments have been made, I have a serious question and that why are you worry about reinstalling Leopard with an Erase & Install which is what I take that you mean when you say clean install. In actually fact there is no such thing in OS X as a clean install.
I am curious because in all the years I have used OS X, I have yet to do an Erase & Install yet.
I know with Windows that they suggest reformatting and reinstalling at the drop of a hat but that isn't true with OS X.

How can I do a clean install of Snow Leopard with out losing iLife applications?

I bought my Macbook pro in 2009 and am currently running the Leopard software. I want to do a clean install of Snow Leopard, but I do not want to lose my iLife applications. I lost the DVD's that came with the computer. Is there any way I can do a clean install of Snow Leopard with out losing my iLife applications?
Will a regular installation of Snow Leopard allow the App store to recognize that my computer has iLife and mark it as a purchased item in my account. If it can, then would I be able to do a clean install and re-download the apps for free.
Any help would be appreciated!

1. Install Snow Leopard normally; this will keep the applications intact. An actual clean installation involves either erasing the partition or creating a blank one, and neither of those will carry the applications over.
2. The previous iLife installation won't carry over to the Mac App Store, and the Mac App Store versions are incompatible with Snow Leopard.

How do I import my address book after doing a clean install of Leopard?

I just finished doing a clean install of Leopard and I realized that I forgot to export an Address book archive before erasing my hard drive. I still have all the Address Book files stored in Application Support in my Library (on my backup hard drive) but I don't know how to get those files into Address Book. Whenever I try the different import options they are all grayed out.
I also have the Address Book files stored on my iPod Touch but syncing with my Touch doesn't seem to bring them into my computer. Is there anything I can do at this point besides entering them in one at a time?! Copying and pasting the files from the backup to the current folder doesn't seem to do any good either. It will tell me that the files I am trying to write over and in use. It says this even after I close Address Book.

Ok, I got is to work by selecting the folder itself and copying it over. Aparently it does work if you open the folder, select all the contents and then paste it. I didn't think it would matter which way you did it.

How can I restore my contacts from a snow leopard time machine to clean instal of Lion

I recently did a clean instal of Lion (which was wayyyyy to difficult by the way--why this wasnt an easy option to begin with I do not know and am not happy about).
In my sleep depravation from the previous problem I accidentally synced my contacts from mobile me to take my computer contacts (deleting all my contacts from my phone and computer).
Fortunately I have a back up on my time machine from my previously installed Snow Leopard.
I tried to restore these files, but they seem to not be compatible.
Steps I took:
1.) -Opened Address Book in Lion
-Opened time machine
notes: i could not go backward in time with lion address book
2.) -Copied files from time machine address book to desktop
-completely unable to open files.
I do not want to use migration assistant because it seems to want to take ALL my files over and frankly thats not what I want to do at all.
PLEASE HELP!

Issues with clean install of Snow Leopard in Leopard MacBook

Hi all,
This is the sequence of events:
1) MacBook from 2007, running Leopard.
2) Got Snow Leopard, did the install on top of the existing OS, just as an "update".
2) After machine restarts, several issues were detected, apparently all OS related: Finder crashed, Apple Mail didn't even open, etc.
3) Download software update from Apple.com (for "performance improvement"). Installer itself crashes!! Can't install update.
4) Decided to go for a clean install with complete restore of hard drive
5) Put in Snow Leopard DVD, boot from it, erase and format hard drive. Got a "Can´t install... contact the manufacturer" error.
6) Don't have my original Leopard OS DVDs at hand at the moment, but will try that later.
Question is: to do a clean install, after restoring the hard drive, do I need to install Leopard first, and only after that Snow Leopard?
(I tried installing Leopard from the DVDs of another MacBook (2008), that didn´t work either. I gather it could be small hardware differences, so I'm still hopeful for when I try with my original restore DVDs...)
Any help will be greatly appreciated!! I mean, this is was supposed to be a no-brainer... :-/

1. You have some peripheral or RAM that is not compatible with the installation.
See my FAQ*: http://www.macmaps.com/badram.html if there are no peripherals attached. You need a minimum of 1 GB of RAM to install Snow Leopard.
1. No peripherals. RAM is only what came with original machine. Have 2GB.

2. Your machine has some hardware issue preventing installation:

3. You are using the wrong installer disc. For a 2007 machine, only a copy of Snow Leopard which looks like * that does not say Upgrade or DropIn or OEM will work.

Thanks a lot for the input! Greatly appreciated.

Clean install of Snow Leopard fails

Dear all,
As the title says my current issue is that I'm unable to perform a new installation of Snow Leopard after performing a single-pass secure erase of the Mac partition of my hard drive. However, some background to the problem is probably useful.
My troubles begin after attempting to transfer files from an USB stick to my Macbook pro. Drag/drop or copy/paste in finder resulted in nothing happening. I ejected the USB drive (which flashed to let me know the drive itself thought it had been ejected) however the USB stick did not disappear from Finder. Further attempts to eject the stick using finder did nothing. Attempting to reset Finder produced the well known "The application Finder.app can't be opened. -10810" error (see http://discussions.apple.com/thread.jspa?threadID=2135129&tstart=45). After reading through that thread and trying some of the suggestions I eventualy had to resort to a hard reset of my macbook. After restarting the macbook ran very slowly for a couple of minutes before producing the same Finder error as before (though no external drives/devices were involved this time).
After coming up against the same problem again and again I decided to verify and repair the drive using the OS X installation cd that came with my macbook pro. The hard disk itself seemed ok (S.M.A.R.T: verified), which I expected as I have Windows 7 running under bootcamp on a separate partition. (As a quick aside, Windows 7 was and still is running fine, and in fact I could successfully access and open all the files on my Mac partition from within windows. This allowed me to grad up-to-date copies of all my important files before taking more drastic action.) Verifying the mac partition resulted in a message saying the disk needed repairing. Attempting to repair the disk initially resulted in errors saying a clean install was required, though the repair succeeded on my 4th attempt. This repair failed to fix the problem and I was still getting the very slow running leading quickly to the same Finder error.
Eventually i decided my only option was to perform an erase and install of Snow Leopard. Initially I simply erased the partition using Disk Utility after booting from the install disk (default option) and then attempted to install Snow Leopard. The install failed repeatedly, alternating between 'An error has occured in the installation process' and 'Unable to install supprting files' error messages. I also tried repairing the disk after erasing and then installing with the same errors. I then performed a single-pass secure erase on the Mac partition (again from Disk Utility via the startup disk), verified the drive (finding an unassigned node error), successfully repaired the drive (twice, just to make sure) and attempted another installation, which again failed with the 'An error has occured in the installation process' error.
So I currently have a formatted Mac partition which refuses to accept a new Snow Leopard install and a fully working copy of Windows 7 running under bootcamp on a separate partition of the same disk. Is there anything else I can try other than reformating the entire hard drive and losing my bootcamp installation?

try this idea: Do a leopard install to an external disk then do a Disk Utility "restore" function to that clean partition. So you restore from the external to the internal partition. Should leave Bootcamp untouched.
