Can't Install Leopard, Won't Recognize Tiger

Hi - I want to install Leopard on an iMac currently running the latest edition of Tiger (10.4.11 or so?). It meets all of Leopard's tech requirements as well. However, when I begin the process, the Leopard install system says it can't install on my iMac because I'm NOT running Tiger.
This is incorrect - in fact, the iMac came with Tiger pre-installed, and that's the only OS it's ever run. How can I convince the Leopard install disc of this fact? I don't see any options for communication besides the "OK" button. It's doubly frustrating because when it then tells me I have to restart, and asks which disk to boot from, it shows my iMac RUNNING TIGER as one of the options.
Is there a way to tell the Leopard OS disk that I DO in fact have Tiger currently installed?
Thanks in advance -

I'm most confused - not hard to do on a weekend morning with only one cup of coffee. If you have the retail Leopard installer it doesn't matter what version of OS X your iMac has. I used the same disk to install Leopard on top of 10.3 and 10.4 so something weird is going on. BTW, BootCamp should have nothing to do with it - my own computers had BootCamp beta when I upgraded to Leopard.
What kind of upgrade are you attempting? Archive & Install or Erase and Install? If you are attempting the A&I what the installer might really be trying to tell you is that there's not enough disk space to perform that installation. Then again, I know that Leopard's installer is able to give that error message properly. The installer might be coming across a weird error when it is checking the drive so run Disk Utility and make sure the drive doesn't need to be repaired.

Can't install leopard, won't even go to installer.

I installed bootcamp on my mac pro. While playing a game I had a serious crash lead to my keyboard and mouse not being reconized when plugged into the monitor.
I decided to reformat. I removed the bootcamp partion and loaded my osx leopard disk. Rebooted, then it would load the apple load screen, but will never go any further. finally I would get a grey screen and I will say that I need to "reboot either by holding down the button or press the reset button. I have never gotten to the install screen.
I even tried my tiger disk and the same thing happened.
I need help!

So I tried just want you said, but no luck I can't get past the apple and the little timer, without getting the restart message.
I tried the disk in my macbook and it worked fine. Could have installing bootcamp have cause some type of problem?
I am going to try a disk clean to see if the optics are clean, but I just installed xp yesterday and it seemed fine.
I do not suspect the HD, being it is loading from the disk.
Urg, I just what to reinstall.

Can't install Leopard onto Sawtooth

Can't install Leopard onto Power Mac G4 AGP Graphic with a 2GHz processor (upgrade).
Tiger runs splendidly!
Any sugestions?!
Thanks

+Just got off the phone with apple support, because I had the same problem. What the problem is here is that the installer looks at the System Profiler to gather this information to make sure that it meets the requirements. Since these upgrades are not yet supported it reads 0mhz processor speed, if it's under 867mhz, it won't install.+
That's is my problem to start with!
I have 2 internal 120GB HD's, the one set as a master runs Tiger and the one set as a slave
have 4 partitions of which 3 partitions are running OS9, Panther, Tiger
and one partition I left to install Leopard.
When I try to install Leopard a pop up window comes
telling me that I can't install it on this computer,
utilities of the Installation disc will read 0MHz.
Try booting from a "virgin" Tiger, just bare OS on the separate drive and partition,
same thing will happened.
some solutions I find @ XLR8 :

But, no joy, just yet.
Never give up!!!
Yes, processor upgrade is not from Apple, but Apple should be more helpful.
If somebody who had a luck with straight install, can put some words of to this post.

Update 10.4.10 destroyed Macbook, can't install Leopard on reformatted HD

Hello,
I recently installed update 10.4.10 on my Macbook. After the update was installed, I was unable to drag any icon outside of it's existing window, firefox, adium, and thunderbird would no longer open, I was unable to run my music recording software and the computer became pretty much inoperable. So I figure now would be the best time to do a full and fresh install of Leopard.
I went out and bought a copy of Leopard and did an erase and install, to rid myself of any problems that may have been internally caused by update 10.4.10 and I get an error that says "Install Failed. The source media may be damaged. Try the install again." So I returned the disc to the nearest Apple store and tried the install with the new one. I got the exact same error, even after reformatting my HD. Every once and a while I'll get an install error that says there is a problem with /MacHD/Volumes/... (which is beyond me). I've ruled out the possibility of an HD problem or CD drive problem because I can still install my original version of Tiger. I've also tried just upgrading from Tiger to Leopard and I get the same error messages. Can some Please help me on this.
I bought a Mac so I wouldn't have these kinds of problems and now my business is suffering because my (new) Macbook can't run the (new) operating system. I feel that Leopard should beable to run on my new machine.
ps. I contacted apple support over the phone and they are sending me a new copy of leopard in the mail.
ANY HELP OR IDEAS WOULD BE GREATLY APPRECIATED.

Not so fast. I'm an admin servicing about 3 dozen Intel iMacs (the white ones) and 2 out of the 6 I've gone to upgrade to Leopard (via archive install) have given me the same message.
I've also had an intel MacBook Pro (1 out of 12 we have) give me this message as well, but it snapped out of it. I've also noticed on several of the MacBook Pro upgrades to Leopard that the hard disc did not show up in the Select Drive install window. I found that if I let it sit there a while (anywhere from 2-15 minutes) eventually the hard drive suddenly appears and I can install.
The white intel iMac I'm dealing with now (regarding the Bad Media) message is a dead end. I've tried two different Leopard discs. Then I tried putting the Leopard disc in a powerbook, booting the iMac into FireWire mode and mounting it to the powerbook. Then running the Leopard install from the powerbook but choosing the intel imac hard drive. I did this to eliminate a bad CD/DVD drive in the imac. No dice.
Finally I opened the thing and replaced the hard drive. After trying to install Leopard into the iMac with a NEW hard drive I still got the message "Can't install ... bad media source ... " etc. message.
Right now I'm installing on another identical iMac and it is proceeding as normal. When done I'm going to use CopyCatX to dup the install.
Never had anything like this with new installs of Apple OS's.

Can you install leopard from an external usb disc drive?

I don't know if the disc drive is fast enough for leopard or something. It's taking forever to open the installer, and when I restarted into the installer it just booted back to my desktop. I have an external disc drive I want to try. Can you install leopard from and external disc drive?

****, I just tried it and when I restarted it didn't go into the installer. I think my disc drive in my old mac mini might be too slow. It takes forever to recognize the disc and just to double click on it and it up. And when I tried to install it the first time from the internal drive it just booted right into my desktop again.

Can I install Leopard on an external drive to run my computer?

Since it seems my hard drive has totally bit the dust, can I install Leopard on the external drive I use for Time Machine, and run my desktop from that drive? Could I run it from an external drive totally dedicated to Leopard? I am buying a new desktop soon, but I need info off of this machine. Can I plug in my Time Machine drive to my laptop and be able to use it without losing data?

Thanks so much.
Youa re welcome!
I figured I would have to use a second drive. At least when I get my new desktop I will have a drive for Time Machine for both desktop and laptop.
If you really plan to keep the laptop around after you get your desktop, I would recommend replacing its internal hard drive. While running your laptop off an external is possible, it should be considered a stopgap measure. i wouldn't do it on a permanent basis. For one, as you'll find out, it's quite a bit slower than when using the internal drive.

Mountain Lion can't install but won't let me quit the installer!

Mountain Lion can't install but won't let me quit the installer! How can I get back to the desktop?

I was having the same problem with my iMac. Couldn't left click with the wireless mouse, i tried all the steps above to no avail. I then tried to use another mouse, this time bluetooth and still had the same problems. I decided to see if my trackpad, which sits in the corner of my desk and never gets used, and then i realize that my cat is lying on top of the trackpad which was causing my problem the whole time.
I hope your fix was as simple as mine.

Leopard does not recognize Tiger install DVD as startup disk

I upgraded my MBP to Leopard. After that, the MBP never recognize Tiger install DVD and Tiger installed extra HDD as startup disk. They have never appear in the startup disk window in system preference. and I tried to use the option key or c key at startup, but they also could not work (just start from Leopard installed internal HDD). On the other hand, Leopard install DVD has been recognized.
I could not find out the same problems in net work.
Does anybody know good solution?
Thanks.
N.B.

In fact, this is the most disappointing feature in Leopard.
Under Tiger I had partitioned my hard disk, with OS 9 running on one partition.
The startup of clean OS 9 worked fine with OPTION key at startup. Now, OS 9 is not recognised any more, none of my old applications are, the volume is no longer recognised as startup option under preferences or when starting with the option key, and I cannot even try to reinstall OS 9 on the partition (in case something was damaged during the upgrade process), as the CD is not recognised when starting up with using the C key... Very frustrating, and I had not heard or read about this problem before.
Only solution right now seems to be> get as much as possible on a DVD or CD, move it to an older Mac, convert, if necessary (eg old Quicktake or PICT pictures, using Graphic Converter) and move them back to the leopard machine. What a waste of time.

WT• Just installed Leopard - won't open any OS 9 programs

Oh God . . .
I purchased Leopard - ONLY because I needed it in order to install Adobe Flash CS3 - which (which I just laid out $800 for . . .
I have purchased through the years, a very extensive library of applications (around $22,000 worth) wich I COULD use in my OSX.3 . . .
Now it seems as though I CANNOT USE THEM ANYMORE!!! ????? IS THIS TRUE?
Tell me there is a patch or something . . anything
NOT ONCE DID I SEE A WARNING on this disk or sales materials: - hey, if you install this-count on throwing away just about every program you bought - and spent HARD DOLLARS ON in your life - cause OS 9 won't work.
God I hope I'm wrong about this, and it's just another install problem.
Pleas help.
Thank you,
Luke

In addition to Tiger on an external disk you can also partition your HD and install Tiger there. You will have to reboot into Tiger, but it will work.
Insert the Leopard Install disk and click Install. After the restart go to Utilities in the menu bar and choose Disk Utility. Select your HD (not the Volume) and click Partition. Follow the instructions to create a new partition (you will not have to Erase the disk—a new feature in Leopard).
After the partition is created, quit Disk Utility and restart. Eject Leopard and insert the Tiger Install disk, click install and go on from there.
When the install is complete you can drag your Classic Apps and other things to the Tiger partition.
Hope this is a small light at the end of the tunnel.

Imovie HD with Leopard won't recognize my Canon ZR40

I have been making movies with imovie HD with Tiger for a long time. I have just now installed Leopard and 10.5.1. Tried to start a new imovie project and imovie won't recognize my canon zr40 which has been working with imovie fine until Leopard was installed. It says no camera attached when I hook it up and try to import. Any ideas? I know it's a Leopard problem since that;s the only thing that has changed in the last couple of years. Hope Apple fixes this because I'm dead in the water here.

Figured it out. From this link:
http://docs.info.apple.com/article.html?artnum=61603
I had an external HD attached by firewire on back of Mac and camera attached on front of mac and I guess this bus conflicts. Unplugged HD and camera recognition worked. I had this before a long time ago with an isight camera but not since then. Weird.

Can I install Leopard on my laptop?

I recently purchased a new IMac,20" G5 with Leopard. I also have a PowerBook, 12" G4 that is running Tiger. Can I install the disks that came with my new computer on my PowerBook? Will Leopard run successfully on that machine? Or am I asking for a whole pile of trouble?
Incidently, when I purchased my new Mac, Apple "migrated" old files on my last desk top to my newest. While it appeared to work fine in the store, within a week there was trouble with every application. I wound up having to re-install the Leopard disk on my brand new computer.
Can anyone clue me in on what went wrong?
Thanks!

The iMac disks are specifically designed for Intel hardware and won't work on the PowerBook (PowerPC).

Mid 2009 macbook pro (10.7.2)- can i install leopard and lion on partitions?

Hello,
I have just bought a refurbished macbook pro and want to install 10.5 leopard on a partition of the hard drive so that I can run my original software that I use on my 2008 Imac (eg Protools 7.4 which would cost hundreds to upgrade as protools 7.4 won't work with snow leopard and protools 8 that would work with snow leopard won't work with my original mbox so would have to buy a new mbox/protools!). The disc 10.5 (leopard) disc that came with my 2008 Imac doesn't work with my macbook pro but would another Macbook pro specific disc work?
Thanks in advance!!
Specs-
15 INCH, MID 2009 MACBOOK PRO
Processor 2.53 GHz Intel Core 2 Duo
Memory 4 GB 1067 MHz DDR3
Graphics NVIDIA GeForce 9400M 256 MB
Software Mac OS X Lion 10.7.2 (11C74)

That machine should have shipped with Leopard, so yes you can install Leopard on a separate partition. However, you will need the original install disk to do so...they are model specific, and you can only obtain these through AppleCare. Call them & see if they will ship you such...there will be a small fee.

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....

Can't install Leopard on Quad 2.6 10.4.11

Finally made the jump to Leopard because all third party plug-ins I use are now compatible (LP8/Abelton Live). Problem: Can't upgrade to Leopard! I put the Leopard disc in, read the install, clicked on Leopard for restart, waited awhile then got a visual of Leopard's Aurora borealis (whatever it is) backdrop and thats it. There was no install option, 'click here,' 'start,''select folder,' or anything else...only the colorful backdrop. It next took me 5 minutes to reset the computer to revert back to Tiger. Everything works, internet, applications, so forth. I called Apple support spoke to them for about an hour and nothing. I also discovered, I can't even Re-install the older Tiger OS either...Holding down C on start up, it goes straight to the Desk-top...the Install disk will not override the system. I even tried to re-set the e-pram holding Apple/Command P and R and got no results. Tiger or Leopard will not install...yet all software works, internet, etc. I've tried to install from the start up disc, holding down C, holding down option, NOTHING. Any input before I take into Apple and pay $75 per hour. Anyone think Techtool Pro or other utility would help?

I failed to mention that I have already run the Tiger DU and repaired permissions...this did nothing. Pertaining to RAM: Apple service asked me about the RAM as well. This is puzzling...I purchased third party RAM but it is completely Mac compliant as far as I know. It was purchased at Fastermac.com. How does the RAM I installed hinder an OS upgrade. When I installed it, I switched the two 512's behind the two newer 2gigs. Do you think if I switched them around again, that this may help? Someone explain why third party RAM has anything to do with it. The RAM I purchased was matched with the exact Quad Pro I own. I've also disconnected all peripherals before install and this did nothing. There are no third party cards. The DVD seems ok. I've ripped movies and audio and continue to do so...I can also install software and updates to other software...just not Leopard. Lastly, Leopard is a dual layer burn?
