Unable to Install Leopard on G4 iBook 1.2Ghz

I have a 15" G4 1.2Ghz iBook with 1.2MB of Ram. I have 13GB of available disk storage.
I get an error of "Unable to install 10.5 on this computer" when I run the Leopard installer. According to the specs I should have no problem installing it.
Any ideas??
TIA,
Jack

Hi Jack
"Apple makes me buy another version for each machine??"
Apple don't 'make' you buy anything, as do Microsoft or anyone else for that matter. If you want Leopard functionality on an older mac model that meets the minimum qualifying specification that's up to you. For that you are going to have to buy the Universal Leopard Installer. This was true for 10.2, 10.3 and 10.4.
As for Steve Job's Ferrari requirements (which could be seen as speculation and therefore not allowed by the rules of these forums to which you've agreed) that's neither here nor there. You can't with a good conscience blame him or Apople for your lack of understanding? As Kiraly points out its all there in the EULA.

Unable to install Leopard on a Dual G5 2Ghz

Okay...I am trying to install Leopard on my Dual G5 2.0GHZ computer with 512mb ram (also tried 1gb and also tried various ram). I keep getting the same result. Computer goes to a gray screen stating, "There was a problem trying to install 10.5 onto this computer." The computer shuts down. I have another 2nd Dual G5 2.0GHZ that's doing the exact same thing. However, Tiger installs quite quickly and runs perfectly. WHAT'S UP WITH THIS?...LOL Has anyone come across this?

PRAM didn't do it. Only an apple keyboard and apple mouse are attached. I've tried 2 other sets of ram which I use in another computer from which Leopard starts. I can't even load the Leopard disc and boot by either internal or external methods because it brings up this error message first (screen turns gray) and then shuts down. Can't even save the message or errors listed because it shuts down immediately. Again, Tiger installed very quickly.
I can boot perfectly from an external hard drive with Leopard on it. With the computer in target mode, I can boot another computer. However, installing Leopard on the hard drive with computer in target mode took quite a long time.
So after installing the Leopard by placing the computer into target mode, guess what it does now?...lol It gets to a blue screen with the curser in the top left corner, which does move to my mouse, it stays like that for about 3 secs. It then blinks one time and in about 2 seconds, the screen is back to blue with the curser in the top left corner. It just repeats that process. Both computers do this.
Any other suggestions?
Thanks for the 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.

Installing Leopard on an iBook with a CD-ROM only

How can I install Leopard on my iBook that only has a CD-ROM? Can I request Leopard on CDs, or can I use an external USB DVD-ROM drive?

Can I request Leopard on CDs,
no.
or can I use an external USB DVD-ROM drive?
you can if your ibook is intel. if it's PPC then you need a firewire DVD drive not USB. also, if you have another Mac, you can boot your in target mode, connect it to the second computer and install leopard from there. The second mac has to have the same architecture as yours (both intel or both PPC).

Unable To Install Leopard to ibook G4

I'm currently using mac os 10.3.9 and I would like to install the new leopard using firewire. After i restart the mac it shows a dialog box stating that i could not install the leopard. Why?

Welcome to Apple Discussions!
A MacBook can't be used to install Leopard on a G4/933 unless your MacBook predates Leopard, and you follow these directions exactly with the Leopard retail installer disc which looks like *:
http://discussions.apple.com/thread.jspa?threadID=1418365&tstart=10
MacBook installer discs labeled as such can't be used on a G4/933.
MacBooks newer than Leopard's release date of 10/26/2007 can't use the retail installer for Leopard unless it was revised since that date, and is newer than the MacBook in question.

Unable to install Leopard

I followed the install instructions. When I select my internal HD as the place to install Leopard I get a message that tell me unable to install on this disk. It suggests I do a GUID Partition and warns me everything will be erased on my drive.

Yes, apparently Apple failed to point out that the old disk format will not support Leopard.
If you run your disk utility app and select your drive on the left you should see, below,
Format : Mac OS Extended (Journaled)
You will probably see Apple something or other.
The only solution is to backup everything, format the HD with the new file system and then install Leopard. At that point you "should" be able to copy back those applications you wish to keep.
There seems to be no other solution to this problem other than not upgrading that computer.
Why did Apple not point this out in their system requirements?

Question about installing leopard on my iBook G4?

I purchased an iBook G4 in very good condition. It came with leopard already installed on it but the seller didn't include any discs with the iBook. Therefore I purchased a family pack (Retail Version) of Leopard off the of ebay for $60. I only have 1 Apple computer but I bidded and luckily won this Leopard Family pack.
Anyways, my question is if anything goes wrong with ibook and have to reinstall the Operating System, will the Family pack of leopard work?
Also will I have to reinstall all the other programs that are already on the computer as well; MS Office 08, iLife 08 etc. ?

Yes. You can legally have Leopard installed on up to any five computers at a time.

Yes, you will. Some iLife apps are included on a Full Retail Version installer, although it is usually earlier versions of those apps. The full suite of iLife apps comes only on the original disk shipped with the computer, or by purchasing iLife separately. There is not a computer specific version of Leopard for the iBook G4, so iLife would have had to be purchased separately. While a new computer wwould have to be purchased separately.
I recommend that you purchase an external firewire HDD and clone/backup your entire computer to it. If you use a utility like SuperDuper or Carbon Copy Cloner you can make a bootable copy of your HDD, which you can update regularly. For more information on external HDDs and cloning please post back and ask.
cornelius
Thanks for replying to my post. Yeah I did purchase a 250GB (Firewire) external hard drive, downloaded Carbon Copy and saved my entire internal hard drive to it. So since I made a copy of my hard drive, do I still need this Retail Copy Leopard Disc?

I'm trying to install leopard onto my ibook G4...why won't it work?!

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.

Leopard is no longer available at the Apple Store but may be available by calling Apple Phone Sales @ 1-800-MY-APPLE (1-800-692-7753).
If you can't obtain a retail install DVD from Apple, look on eBay or Google the installer part numbers to possibly find at an on-line store. Here's what to look for:

Unable to install Leopard... help?

It's my 4th time trying to install Leopard on my Imac G5.
When i put the DVD in and choose the restart option as stated, the computer restars but i never get to see the intall screen. It stays on the apple grey screen and nothing happens...
I have to restart and hold the eject key to be able to get the DVD out...
Once the DVD is out, my computer works just fine, but as soon as i start the installation process again, the same problems happen.
Anyone had the same problem?
thanks

I understand your need to preserve your applications and files. Formatting always takes up so much time. However, when troubleshooting, it does eliminate your pre-installed stuff as a source of the problem.
Another alternative would be to do an archive and install. That will at least keep your applications and files. Needless to say, you should have a backup of everything, so you should be prepared for everything on your boot drive.

Unable to install Leopard on MacBook Pro G4

I have a 2.16 GHz PowerBook G4 with 2 Gig of memory. When I try to install Leopard, I get as far as the restart. That it won't do. It comes up and says that it cannot be used as a start up disk and to make sure that the install disk is loaded. Well it is loaded, obviously, so what is happening? Why won't it continue into the installation. This is a brand new purchased disk.

I do not recall it being a G5
There was never a laptop from Apple with a G5 processor.
so it must be a G4 unless that designation is not used for the Core 2's.
"PowerBook" and "G4" only applied to the earlier laptops from Apple that contained the PowerPC G4 processor. Neither term applies to the current Intel-based Mac laptops of which the MacBook and MacBook Pro are examples. It's not a "technicality"; it's critical to identify correctly what model of Mac you have so that people give you appropriate advice. What works on one model of Mac doesn't always work on a different model.
That said, I repeat my question: have you tried booting it by inserting the CD, restarting, and holding down the "c" key? If not, try that and see if that will boot the system.

Installing Leopard on my Ibook G4

Hi everybody !
I have recently bought a late 2004 Ibook G4, 1,25 gb RAM, and so on, which is running under Tiger OS (10.4).
In my home, I also have (and to be honest, that was my first mac) an Imac, whole aluminium shaped, early 2008 I think, on which Leopard was installed with, and upgraded to Snow Leopard.
My question is than can I Install on my Ibook G4 Leopard OS with the installation CDs (well, the grey/green ones) which were in the box with my Imac ? (Possibly not as an upgrade, but from O).
Thank you a lot for your answers,
Best Regards,
T.

Hey all,
I have a quick question, looking for some support. I have an iBook G4 with my specs listed below:
Machine Model: iBook G4
CPU Type: PowerPC G4 (3.3)
Number Of CPUs: 1
CPU Speed: 933 MHz
L2 Cache (per CPU): 256 KB
Memory: 640 MB
Bus Speed: 133 MHz
I am currently running OS X 10.3.9 and am wondering if my situation is sufficient enough to upgrade to Leopard. From what I understand it should be fine, I am just looking for a second opinion..
Thanks for any insight

Unable to install Leopard on Mac Pro tower

Hi all,
I have a Mac Pro w/ 1gb RAM. It installs and runs Tiger just fine but is having problems getting up to Leopard.
When I try to boot to the DVD, it just sits at the grey Apple logo with the spinning icon (not beach ball). I've let it sit for hours and nothing comes up on the screen. No audible noise coming from media drive or the hard drive.
I've tried Target mode which yields the same results. There are no external devices or non standard PCI devices attached to the computer.
I am using a legit Leopard DVD installer and the Mac Pro has been wiped clean using disk utility. I've also reinstalled a clean version of Tiger and tried to upgrade (vs. clean install of Leopard), which also gives me the same results.
If I try to boot to the hard drive, I sometimes get the "purple space" Leopard screen, but all I do is watch the beach ball spin. Whats even more odd is that I never went through the Leopard install so I don't know where that's coming from.
Help!
Thanks in advance everyone

Thanks for the reply.
OK, I get none of those options as I never make it to the setup screens. I would like to do an erase and install, but again when the disk is blank or has a fresh Tiger install, I still don't make it past the Grey Apple icon screen.
I'd even take an Upgrade install at this point, but its not letting me do that either. After I did the erase/install Tiger install, I upgraded to 10.4.11 and popped the drive in. Clicked the installer icon which asks me to reboot, and I start all over with the above problems.

Unable to install Leopard from install disc

My MacBook stopped booting recently due to a "INvalid Sibling Link" error and I decided to reinstall Leopard from the installation disc. I booted using it but I get an error saying "Leopard cannot be installed on this computer."
THe log says
"Installation checks failed.
Installation check failures: This software cannot be installed on this computer."
Apple's help says that I need to update my firmware but my laptop came installed with Leopard. Why is it not installing now?

Possibly:
1. You need to reformat the hard drive.
2. You are trying to install when an existing version is on the drive.
Before you reinstall OS X do this:
Extended Hard Drive Preparation
1. 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 drop down 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 then click on the OK button. Click on the Partition button and wait until the process has completed.
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.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
After formatting has completed quit DU and return to the installer. Complete the OS X installation.
