5 hours to install Leopard 10.5 on 24" iMac 2.8 (2008-Dec purchase)?

We were running SL on the 24" iMac for several months w/o a glitch, then after a power failure (Storm in DC), every action was taking forever and the spinning color ball was present more than not. So, we ran Disk Utility (DU) and found internal HD in need of repair. We booted from SL CD (box set) and tried to repair, but found the disk unrepairable. We erased the disk using DU (as we have TM backups) and tried to complete install of SL, but install failed.
I again erased disk using DU, verified that disk was OK using DU, then tried a second time to do clean install of SL-- after several hours, failed again.
Next, I dug up the 10.5 disks that came w/ the iMac and began clean install after running DU to repair the HD. So far, the 10.5 install has been running for a couple hours and status bar shows 4 hours to go. This cannot be normal or is it?
The install Error Log has 3 line items, something like:
-(65)Folder Mgr is being asked to create a folder...while running as UID 0
-(144) same msg as above
-(375)File doesn't exist, will create...
Can it possibly take this long to install? Given two different install sets failed (10.5 and 10.6), I'm guessing there is either a disk problem or some other HW problem.
Any suggestions?
iMac is under warranty, but we're under 2+ feet of snow and accumulating here in DC (Alexandria, VA actually). Spouse is Architect and needs iMac to design while we're snowed in...boy, this is a double dose of Snow...

agree with sig. definitely sounds like a bad drive. I suggest you interrupt the install and 5 hours for an erase and install isn't normal. you may want to run apple hardware tests to see if something else is possibly afoot. reboot with the original leopard disk inserted and hold "d" at the chime. this will boot you into AHT. run all tests.

12 Hours to Install Leopard? Combo update 4 hrs

Hello and TIA
I have the unit below, and it required 12hr to install Leopard 10.5.2 from disc. (erase and install)
The combo updater as indicated by the Software update is now requiring about 4 hours. Is this normal
The reason I did a complete erase and install was my MPro was getting slow and the beach balls. I ran checks on the disc, appears fine? RAM appears fine also
HELP!
Don
I unplugged all the unessesary devices and etc, ran Disk Utility after install?
Any ideas?

Curious and perhaps helpful. Your ratio of installing Leopard to the update is 3:1 which is very close to what I got, only much slower. I just thought of this.
Your numbers are consistent and it takes your optical drive out of the equation.
Your HD may have bad sectors or you may not have enough RAM, but whatever it is, it's simply slower.

Install Leopard with Firewire on G4 imac

I bought a 1ghz G4 imac with 768mb memory. I am using firewire to install Leopard on it from a Macbook 2008. I create a new partition, I apply GUID. It installs fine. On the Macbook screen it shows up fine. When I disconnect the firewire, drag the hd image of the G4 to the trash on the Macbook screen and turn on the G4, all I get is the flashing folder/face. I hook it up again with firewire to the Macbook and the install shows up. What step did I miss???

Are you using a retail copy of Leopard? If it's the one that came with your MacBook, it's machine specific and won't install on your G4. GUID is an intel partition method, you need Mac OS Extended (journaled).

Install Leopard on new 27" Intel iMac

We're still a CS3 house, no funds to update all the hardware and software to enable us to upgrade all our users to CS4 ... until late next year. In the meantime, everyone is running Leopard (G4s, G5s, and up).
In the meantime, however, we've purchased several new 27" iMacs, all of which come with Snow Leopard, which we cannot downgrade. I spoke with an Apple tech today, and was told that I could partition the hard drive to install Leopard and Snow Leopard, but I don't know how to do this. Since the new iMac will NOT boot to the Leopard DVD, how do I get Leopard onto the second partition? I've created the partitions and Snow Leopard is running on the smaller partition. Migration Assistant will move the users, apps and files over to the other partition, but not the O.S.
Can I simply just copy the Leopard System Folder from the old QuickSilver (which the iMac is replacing) onto the partition on the iMac which I want to run Leopard? I know this used to work in the olden days ( ... sigh), but I'm doubtful that it's that easy these days.
Thanks for your help.

I understand how the budget is the budget--and that it will only stand so much.

Unfortunately, the tech gave you bad advice. You won't be able to run Leo on your machine.

Unfortunately, no. The good old days are gone. You won't even be able to run Leo on an external drive.

Installing Leopard (OS 10.5) on iMac G5

I have tried several times to upgrade the operating system on a G5 iMac but have been unsuccessful. I am using the retail family pack DVD, have removed all peripherals except for keyboard and mouse, but cannot get further than attempting to reboot from the DVD. It starts to load but gets hung up on the spinning little spoke-like wheel thing on the gray background, which spins endlessly until I turn the power off. I have tried using my other iMac as an external drive with a Firewire in the target-host mode but get the same result. Any suggestions are welcomed!

1. Unless you have a family pack, you shouldn't use the same disc on more than one Mac.
2. If your Mac has a drive issue with its optical drive, and is a G5, you will need a Firewire DVD drive to load Leopard.
3. An iMac G5 will not boot from any system specific disc for any other Mac.
4. 'C' key is not reliable for booting. Try the Startup Manager, if you believe your optical drive should work. That's described here:
http://support.apple.com/kb/TA27043?viewlocale=en_US
Only you'd select the Leopard installer disc, and not the hardware test.
5. If your iMac has 10.4.11, and you are upgrading, be sure to follow these steps to upgrade*:
http://www.macmaps.com/upgradefaq.html
6. Target Disk Mode installs only work between similar models and vintage Macs:
An iMac G5 can't install to an iMac Intel. Only an iMac G5 from August 2005 will install to another iMac G5 from August 2005.
For more on installing to broken optical drives, see this article:
http://discussions.apple.com/thread.jspa?threadID=1418365&tstart=0
7. Before assuming your drive is broken, if it is more than 4 years old, you may need to replace the clock battery. After which point you may need to zap your PRAM:

Disk Utility Issues Wait to Install Leopard

Dear fellow Mac users,
Rather than a question, this is a recommendation to those who are wondering whether to install Leopard now or to wait until it gets really stable.
My experience in installing Leopard has not been positive and I chose to revert to Tiger. After discovering several issues and going to the "Genius Bar" of the local Apple Store, I fortunately have been able to restore all my previous settings.
The loss has been mostly time and money, and they frightened me up suggesting that I had to change my hard drive. For those who might experience similar problems, let me provide some details.
1. Installation of Leopard
After carefully making a bootable backup of my HD on an external drive, I installed Leopard choosing the Option "Erase and install." This occurred without visible glitch. After updating the system to its latest version, I migrated all my data and settings. The result was an incredibly slow system, completely useless. It cannot have been the results of my settings, because I also created a "clean" account called "Maintenance," with the same results. On the recommendation of the "Apple Genius" I also added 1 GB of memory, getting a total of 1.5 GB of RAM installed to the cost of $150. It did NOT improve the situation.
2. Disk Utility
Because I suspected problems with privileges, I tried to run the Disk Utility. The result was an endless spinning wheel. After waiting several hours, I had to force quit the application. Tried to run it from the install DVD of Leopard, with the same results. People at the Genius Bar also tried their disk utility after booting from an external drive, without any success. They diagnosed a probable failure of the hard drive and recommended that I replace it. Fortunately, I didn't trust this groundless recommendation and made a last attempt by erasing Leopard and reinstalling Tiger. Now it runs just fine, and there is not the slightest mechanical problem. Apparently, and I only discovered this today, the whole disk check procedure changed with Mac OS 10.5, and at this stage it is a complete mess, with enough bugs in Disk Utility to keep the developers busy for a couple of months. I came across discussions of this on the Mac FixIt Website.
Thus, my recommendation at this stage is that if you have Mac OS 10.4.11 running fine you JUST STICK WITH IT and be patient for a few more months. Upgrading at this stage amounts to loosing time, energy, and money. Of course, I am sure that Mac OS 10.5 has many promising features and look forward to using it in the future, but not now. I would be happy to hear contradictory opinions, if any.
Best wishes for patience.

Nerowolfe,
I have installed Leopard and have had nothing but problems as well. Perhaps you can help me. I am ready to roll back to Tiger. These are just a few:
1. I cannot mount my external firewire drives. I have separately tested each and they work fine, I booted with the Tiger disk and they mounted fine, I reset the firewire port and when I connected them they mounted on my desktop, but not in the finder window and when I tried to open one, it just hung. I have been unsuccessful after many attempts to mount one of them with Leopard.
2. I appear to get random hangs. I have a 160GB hard drive and 2GB memory. I have 42 GB space left on the hard drive....yet I continue to have random hangs, especially when I try to open disk utility
3. Spotlight just does not work, period
4. I keep finding locked folders. Right now my CS3 is locked and even after going into get info and unlocking it, it just locks back and I am unable to open the application. I am a photographer and have been unable to do any work for the past 2 weeks while I am messing around with my computer. Now I have Christmas photos to sort and can't access the photos on the external drives or even open CS3
I have searched the forums, tried many of the recommendations, but nothing is working for me....perhaps since you have been successful you could give me a hand with these issues.
I wait for help.......
Other than that, how do I uninstall Leopard and reinstall Tiger????

Mountain Lion won't install on 10.7.4. Suggestion from Apple is to completely erase harddisk and install Leopard Snow Leopard Mountain Lion. Is there no other way to install Mountain Lion

Mountain Lion won't install on 10.7.4. Suggestion from Apple is to completely erase the harddisk and install Leopard > Snow Leopard > Mountain Lion.
Is there no other way to install Mountain Lion?

I tried and failed for several hours to install Mountain Lion, and was repeatedly getting the "Recovery System" cannot be created error. I tried all the tricks: resizing the drive partition, booting from an external boot drive, all to no avail. After reading other users struggling with the same issue, I had determined it to be a boot camp drive error. However, I didn't want to have to erase and begin anew when I came upon a possible solution. I had long ago renamed my boot camp drive with a "." (".windows" for me) in order to avoid having the partition show up on my desktop. So, I boot into windows and renamed the c: drive without the "." ("windows"), and reboot into os x. The install then went off without a hitch. I hope this will be helpful for others struggling with this issue that may have renamed their boot camp drives in a similar manner.

Unable to install Leopard onto my iMac G5

This is my first post here so please be patient with me if I do not do a good job explaining my problem.....here we go.
I have a 20" iMac G5 purchased back in 2004. It is what I believe was referred to as a special edition and came with a wireless keyboard and mouse. It currently has the minimum 512 megs of ram (I've ordered 2 Gigs for it yesterday), 150Gig HD, 1.8Ghz (not at the computer right now so cannot confirm the CPU speed). It currently is running OS 10.4.11. Ok, now onto the problem.
I tried to install Leopard Family edition, which I purchased at an Apple Store. I have tried and failed to install 10.5 four times now. The first attempt would not even pass the DVD check. It says the install DVD is damaged. That is not true because it loaded just fine on my wife's 12" Macbook.
In any event, I do have an external HD which is used for backup, via SuperDuper. Therefore, I have not lost data in case you are wondering. Each time I installed I would select the erase and install option. Each time, I get a different error. It will pass the DVD check then fail about 15 minutes into the install. It will give a yellow triangle window and say the Source Media is damamged. Another error in another install attempt says something to the effect that it cannot find something (cannot remember what) on the destination drive.
After these attempt, I reinstalled 10.4 and managed to get the system running again. I repaired permissions and ran the Verify Disk from Disk Utility and everything checks out. I had a technician come help me and ran DiskWarrior and seem to believe the HD and permission are fine.
I have had a few problems prior to the Leopard install, which may be the problem to begin with. Mainly two problems, the computer will not always come out of sleep mode when clicking the mouse and/or keyboard. I also have had many Kernel Panics. These two issues have ocurred over the last year but have increased in frequency. Have not seen a Kernel panic since I reinstalled 10.4.11 but still will not always come out of sleep mode. BTW, I did get a USB keyboard (not apple) and a mac mouse and have been using them since last night.
Ok I will stop here for now. I aplogize for wordiness and disorganization. Please help..

I received my external DVD drive and tried to install Leopard. No success. I get the same error. It appears to fail about the same time. It spends some time doing work before it calculated the estimated install time. Just after it calculated an install time (about 3 hours) that is when I get installation failed error. To me, it would eliminate the internal optical drive.
At this point, I am at a loss of options. I could replace the Hard Drive next I guess. I am beginning to wonder if I should just save my money and buy a refurbished Intel iMac....
I did buy 2 Gigs of RAM (EDGE) which is supposed to be compatible with my system. When I installed it the computer would start buy the screen stays dark. About 30 seconds after startup the cpu fans spin up to full rmp and the computer remains that way until I hold in the power to power down. I tried removing the RAM one at a time and still no joy. I finally removed it and reinstalled the 512 ram and the computer booted no problem. I have already talked with the site I bought it from and I am going to send it back.
If anyone has anymore comments I would be most appreciative for additional help.

Should I install Leopard on my iBook G4?

I have read some of other people's experiences in these Apple discussions but want pose the question again with the specs of my own computer. I have an iBook G4, purchased in early 2005, running 10.4.11, with a 1.33 GHz processor and 1.25 GB of RAM (I just upgraded from 768 MB of RAM). I am liking Leopard on my new iMac and would like to upgrade to Leopard on the iBook, especially since I could then use Time Machine to back it up easily to an external hard drive. Should I take this step? How much free space on my 80 GB hard drive should I have in order to make this move? (I now have only 11.75 GB, which I know is not enough, as Leopard takes 9 GB, but I use the iBook for work and could conceivably take off some personal items such as music and photos. By the way, I purchased the iBook myself for work, so I am not breaking any work rules to have personal stuff on the computer.)

Thanks to all of you who gave me the confidence to install Leopard on my iBook G4. I did it very methodically. First, I purchased 1GB of RAM, which, when installed, gave me the maximum of 1.25GB of RAM. Then I pared down my music and photo libraries so that I had a much bigger chunk of free space on the 80GB hard drive. Then I installed Leopard. First I waited for the DVD to be verified (a longish process), but then the installation went very smoothly. All in all, it took under 2 hours. I realize I won't have some of the graphic animations in Dashboard, but I think the advantage of having Time Machine will outweigh that. Thanks again, folks, for your advice.

+ 2 hour upgrade to Leopard from Tiger on Brand New imac 20"

Forgive my upcoming ignorance as this is my first Apple Computer and I know very little about Apple overall but I know a LOT about PCs and Windows.
I just purchased an imac, 20" Intel 2ghz Core Duo, LAST NIGHT.
From out of the box, to plugging in the computer and peripherals, to getting into Tiger for the first time and putting in the Leopard upgrade disk.
Is 2+ hours normal to do this upgrade.. this upgrade took FOREVER. I've installed many operating systems on PCs, mind you I'm installing Windows but it's never taken me 2+ hours to install an Upgrade to an OS on a reasonably fast machine. I've installed / upgraded linux in less time.
I can't believe this is normal and have some concern as to there being an Issue with the Combo Drive or something else?
There's no lights to indicate disk activity or anything during the installation, this is something I'm quite used to in the PC world, to be able to tell if the computer is accessing the Hard Drive or the CD/DVD drive with little lights or even noise. The only noise I heard was scattered disk noises and a random spin up of the CD Drive every so often.
The only visual indicator on the screen was the progress bar during the installation with a Time indicator that seemed to be having as much difficulty as I was in figuring how long this should take. Frequently it would jump from 1 hour 40 minutes to as much as 2 hours and 50 minutes estimating installation time.
Any experts here have any insight on this? Is this normal? Am I missing something here... I would hate to endure another upgrade or install that will be this painful in the future.
Thanks for your input and time on this!

Ah yes, I remember 95, infact, I did install this version from floppy, it was 27 floppies if I remember correctly.... at least I was doing something if it took just as long, so I don't think that install was as agonizing as this. Thanks for the memories.
C'mon though... what's up with not having any indication that the computer is doing anything at all while it's installing.... Couldn't apple make the little Apple logo on the front blink or something when there's disk activity. Seriously, I like that the Mac is quiet, but I don't like having to put my ear to the side of the case to hear if it's doing anything. If I hear the cd whiring or the disk crunching I have a good indication there's activity but through this whole process the CD only spun up in short spurts every so often.
I was wondering if this install was recompiling kernals or doing something ... the time indicator bar as my only means to an estimated guage is very silly to me!
I thought about that when I installed and even posted about those seemingly long times when nothing seems to be happening and cautioned the rush-hour crowd to be patient.
I think I have an answer, but it may be stretching things: many Mac users, I have noticed don't like things like desktop items, even if it's only one or two. One did not even like the Dock and wanted it gone - not hidden as most of us set it, but gone. Finito! And for years there were only one-button mice available and no BSD under the hood. So I think this lack of information is only annoying to people like me who came recently from the PC world (and am still in it) but the Macophiles probably like those blank information-less screens. I do recall once that Apple ran an ad saying "Who cares about MHz, GHz GBs and such - it's the color (flavor?) that counts. Fortunately, Apple has come a long way from then and attracted people like myself who do care about what is under the hood.
I suspect as more and more get involved in the BSD stuff and X11 and such, that these indicators will become more prevalent. At least I hope so.
An obvious bug when using DU, in 10.5.1, however, is that when doing a verify, my odometer says 1 minute left for about 5 minutes and then backs up and says 13 minutes left and drops about 1 minute every few seconds. In 10.5.0 the barber pole spun for a long time with no information.
Still, these are reasonably minor glitches and certainly not show-stoppers.
All-in-all, I look at Leopard as a distinct improvement over Tiger in almost every area. I miss Sherlock - which is why I keep my bootable Tiger clones up-to-date and working properly.
Interestingly, I have 3 Macs and 2 PCs and 5 Windows programs running on them.
Contrary to what others say about Vista, I find it running quite boringly well on this MBP. It's the 64-bit version and I did have to find the network drivers on my own.

Install Leopard on an External Drive on a Snow Leopard Mac Book Pro

Hi
I have a MBP 17/CTO 2.66GHz i7, which came installed with Snow Leopard.
I've used boot camp to install Windows 7.
I've attempted to install Leopard 10.5.4 on an external drive.
The steps I've taken:
1 - Connected my WD Passport on the Firewire Port
2 - Partitioned the drive. The first partition is 100GB, Mac OS/X Extended (journal) and I've selected the GUID Partition Scheme
3 - Inserted the Mac OS/X Leopard DVD, and followed the instructions to restart
4 - On restart I have three options. Mac OS, Windows and Install Mac OS\X
5 - I select Install Mac OS\X.
6 - The disc spins for a few moments and then the laptop freezes
Beware of the following issue:
1 - On restart more often than not, the DISC will spin and then the laptop will freeze.
2 - To overcome this, restarting pressing the ALT (option) Key.
3 - You should see your boot options. If you do not see "Install Mac OS\X", then eject and reinsert the disc.
The question maybe why would I want to have an Leopard Installation when I have Snow Leopard. The software I develop has thrown up a number of differences between Leopard and Snow Leopard, hence I need both OS's to support my software.
I mentioned this to the Apple Store before I purchased my machine. They put me through to a senior technician at Apple Care, who told me it would be possible to have the set up I am after; and to contact Apple Care if I ran into any difficulties.
After I received my laptop and ran into the problems I described above I contacted Apple Care, only to be told by a senior technician that it should be possible to install Leopard on an external drive, but Apple Care cannot provide any support or assistance.
I really do like the laptop and would much rather not return the laptop; but I really do need the setup described.
Anyway I have tried a number of different approaches:
1 - Having no partitions (so just the single partition)
2 - Trying all three Partition Schemes:
- GUILD Partition Table
- Apple Partition Map
- Master Boot Record
All resulting in the same problem.
I can confirm the external drive does appear as bootable in disc info.
My guess is one of the following is preventing the install:
1 - It is simply not possible to install an earlier version of Mac OS\X than 10.6 on the laptop I have, even if I tried to install on an external drive. This restriction is built into some hardware confirguration. So even if I wiped the internal hard drive or added a new partition to the internal hard drive, I would not be able to install 10.5.4. I say this may be a reason as the second technician told me the CPU has built into it a process which prevents installing older versions of Mac OS/X, but that it should NOT restrict installation on an external harddrive.
2 - When trying to install Mac OS/X, a search is carried out for an external drive which has the correct format. For some reason it may be that this search is not finding my external drive?
I'm a little stuck here and quite disapointed that the support promised by Apple Care for assistance in setting this up, is now not forth coming.
Any help or suggestions would be appreciated, as ideally I would prefer to keep and not return the laptop, it's a beautiful piece of machinery.
Cheers
Parmy

The mystery continues...
I have an older MBP (2.33 GHz Intel Core Duo) which came installed with Tiger. I can confirm I purchased a genuine copy of Leopard (10.5.4) from the Apple Store and it’s not an OEM version. I installed 10.5.4 without a hitch on my old MBP internal drive. It is the only OS installed on my old MBP.
Using my older MBP (which through software updates is now running 10.5.7), I managed to install 10.5.4 onto my external HD (WD My Passport Studio – 640GB FireWire 800).
However; on the final restart, the screen remained grey and 10.5.4 did not boot from the external drive.
I restarted the machine holding down the ALT (option) key, and only two options appeared, Macintosh HD and the Install DVD. I selected the Macintosh HD and opened System Preferences.
In System Preferences --> Startup Disk, I discovered the partition on my external HD which contains 10.5.4. I selected this partition and selected restart.
On restart my MBP displayed a grey screen, and the blue light on my hard drive flashed slowly. I left this for an hour, however; the OS did not start and the screen remained grey.
I then plugged my external HD into my new MBP which I started holding down the ALT key.
To my surprise I found 3 boot options (Macintosh HD, Windows and Leopard). Leopard being the partition on my external drive, which now has 10.5.4 installed.
I selected Leopard, but sadly after 30 minutes, the OS failed to boot.
Although this deviates slightly from this post, I fail to understand the problem here:
1 – Why can’t I boot 10.5.4 on an external drive, from my old MBP? Surely this is not because my old MBP is now running 10.5.7?
2 – Why can I see 10.5.4 as a boot option on my new MBP but not on my old MBP when I start the MBP holding down the ALT key?
I doubt there is a problem with my external drive, as it seems to read, write, etc... in all normal cases.
Whilst it definitely appears that I won’t be able to boot 10.5.4 on an external drive from my new MBP, I should be able to at least boot it from my old MBP, which would give me the option of installing Snow Leopard and Windows on the internal drive of my old MBP.
Apologies for keeping this post going, but I hope by getting to the bottom of this, it will help other Mac users as well.
I’ve run out of ideas of things to try, so I will give Apple Care another call in the morning, and will report back.
Any suggestions of other things I can try?
Cheers

Installing Leopard on new hard drive

Want to replace HD on my dual 1.8 G5.
How do I go about starting, formatting and installing Leopard on a new blank drive.
My old drive is backed up on an external using TimeMachine.
After install I plan to pick and choose what to replace from TimeMachine.
Thanks for any help.

First:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must 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 or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Quit DU and return to the installer. Have your TM backup drive already connected. When installing you will be provided the opportunity to restore an old system from a TM backup. I believe this will appear after completing the Setup Assistant.
If your old drive is still functional then you can put it in an external enclosure, boot from it and clone it to the new drive after the new drive has been prepped per the above.

I can't install leopard on my powerbook G4

I have all of the system requirements needed to run leopard 10.5 on my computer. First I bought leopard and cleared the disk verification, I get the "base system error." I called for support for 2 hours and the man said it was an error on the installation disk. However, after exchanging it for a new disk I encountered the same error. So I took my laptop down to the store and a genius said it was a problem with the hard drive and that once I got it back leopard would be installed with a new HD. NO, despite the claims on the terms of the apple care contract they had not installed the most recent version of OS X, which I paid for. When I got my laptop back after 2 weeks of ordeals of shop repair, i get back what appears to be my RAM in a bag and a now scratched leopard disk. So I try to install leopard in the store and once I put the disk in the screen turns black with the pin wheel of death. Now it won't even make it to the installation phase! What is going on! They took it back and now I'm out of a computer for another week. So I would appreciate it if anyone knows anything about my problem and what happens if apple is unable to fix my computer. Do I get a new computer that is able to run leopard like apple claims? Do I ask for a refund of my 2000 dollars I paid for the computer? Thank you. <Edited by Moderator>

+"I can't see that it's too much to ask to be able to use those purchases as I wish, do you?"+
You are entitled to use the software that came with your computer +on that computer+. Period. Each machine comes with it's own software. If you want to upgrade the software that came with the computer, you have to pay for the new software. So, in this regard, yes, it's too much to ask. "Piracy" is an accepted term for misusing software in violation of the EULA which you must agree to when you install the software. If you violate the terms of that agreement, you are acting illegally. If you don't want to call it piracy, how about stealing? Ripping off? Whatever. Prisons are full of people who figured the law did not apply to them or that the law was "wrong" or "excessive". But it's still the law....
