Installing Leopard(10.5) keeping Tiger(10.4)

Hi everyone,
How do I install Leopard keeping Tiger to be able to switch between the 2 operations system? Will I be running in endless problems If I do such a thing? The reason, is that I need Leopard to run OsiriX 3.1(processing software for medical images) and was told that CS2 is not agreed with Leopard, so need to keep Tiger.
Hopefully they could get along!
Thanks!

I have Power PC G5 (not intel), and already using the other SATA connection on motherboard (only 2) for external hard drive for Final Cut pro 5. I think the best would be another hard drive with Firewire which I would use only for OrisiX. Is is pretty straightforward to install an operation system onto an external hard drive?
Thank you for your time!

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.

As a vision-impaired user of a 1.25GH ( 1.25MB RAM) iMac G4 I am very reluctant to try to install Leopard on it (running Tiger at the moment). I want to have all my old non-Apple apps there. Robert Davis.

As a vision-impaired user of an iMac G4 (1.25GH and 1.25MB of RAM) I am very wary of putting Leopard on my system. I know if I do a clean install I'll have to put all my software back on which would take me ages as I have stuff in OS 9 as well running in Classic, but if I do an archive install I know the Apple software will go in but what happens to all my other apps? The preamble on the disk doesn't make this really clear. If it is too difficult then I guess it's time for a new Intel model but I like the G4 as I can get my face right up in the screen without having to move the computer, something you have to do to with the new models. Can anyone help - I don't want to be stuck for a month without a computer until my stepson comes back from holidays as he is head of IT at a school school that run all Macs. Please excuse any faux pas in this - I am new to the support community.

You could use A&I, selecting Preserve Users and Network Settings. This should keep your third party apps but you will lose Classic and OS 9, which are not supported by Leopard. Before upgrading, I would also check to see which third party apps may not be Leopard compatible or will need updating.
If you still want to proceed, you should definitely have a cloned bootable backup of your current setup, in case you need to revert, or find something possibly missing after you upgrade. I wouldn't make a move without one. I use Carbon Copy Cloner. You could keep the old setup that includes Classic and OS 9 on a separate partition on an external drive and still be able to work from that when needed.

You might find some apps that are not Leopard compatible.
You will also need enough free drive space to accomodate the new OS, as well as the Previous System Folder.
I don't see why you wouldn't be able to get your face right up to the screen of any of the new iMacs. And you can have a much bigger screen, 27". But you will be stuck running Lion, which will try to turn your computer into a giant iPad. A refurb might still be able to run Snow Leopard.

I am upgrading from Tiger to Snow Leopard. I keep getting an error when I try to load the Mac Os x update combined. It says that it was corrupted during download. Have try loading from Apple website V10.6.7 upgrade combined but it still won't do it?

I have an Intel Desktop iMac and I am upgrading from Tiger to Snow Leopard. I keep getting an error when it tries to load the Mac OS X update combined. It says that it was corrupted during download. Have try loading from Apple website Mac OS X V10.6.7 upgrade combined but it still won't do it? Any other suggestions. The printer is not working either - I am not sure if they are connected. Everything else is fine.

Please excuse, but I have to ask an obvious question: Did you already update using the Snow Leopard Retail install DVD? (You must do this first; 10.6.7 is just an update if you already have 10.6.) Are you, then, trying to update from whatever version was on the install DVD to 10.6.7?
Otherwise, I'd keep trying. The 10.6.7 Combo is a huge update.

Upgrade to Leopard and keeping Tiger just in case?

I have a dual 867 G4, 2 Gig ram, on 10.4.11 and runs great. I had held off Leopard because of slowdown concerns. Logic Pro also is fine. I will be getting a new machine by spring, but now some of my app upgrades are leopard only. I wanted to keep Tiger around just in case Logic etc. slows down in Leopard or if Leopard didn't work with some older apps. How can I do this the best way, or is it not worth doing at all? I don't use haxies but my system goodies go beyond the Apple install which I want to use on both OS's. thanks.

You could clone your current internal drive to a firewire external drive before you install Leopard. This way you have backup in case the upgrade goes badly and if all's well you can keep the backup as a Tiger boot drive.
Make sure you use the correct partition map for you Mac, ie. Apple Partition Map for non intel Macs and GUID Table for intel.

ITunes keeps unexpectedly quitting after installing Leopard

After installing Leopard, iTunes keeps unexpectedly quitting? I've tried recreating the iTunes library with no help.

i had the same problem. finally i found out what was going wrong. it was the digi core audio extension that messed up my itunes. so if you are using pro-tools you should have a look into this possibility.
if not you might want to try and remove any non-apple audio extension and see what happens. don't trash them as you might be able to pin point the problem to only one extension.

Install Leopard & Tiger on different Mac.

I just purchased Macbook (Leopard). Usually when we purchase a Mac computer, the OS will include. Can I Install Leopard on my old Mac computer (MacBook Pro-Santa), and Tiger on my new Macbook? I just purchased Macbook (Leopard). Usually when we purchase a Mac computer, the OS will include. Can I Install Leopard on my old Mac computer (MacBook Pro-Santa), and Tiger on my new Macbook? I need some opinion. Thanks. Sorry for my English.

To expand a bit on Niel's answer, you cannot instal an OS on any machine that is older than the machine itself. If your machine comes with Leopard, you can't put Tiger on it, and the Leopard install discs that come with your new MacBook are machine specific and won't work with your old machine.

New Macbook Pro + Tiger Pre installed Leopard Connectivity Problems!!!

hey guys... well let me try for the 2nd time to post this before it loses connection and crashes!!!!
on Friday i brought a new Macbook Pro 2.2ghz, for the last year i have been using a MAcbook 1.8ghz Core 2 Duo... worked flawless and loved it... but with Leopard out, i decided to take the plunge and move up to the next level and have something with better graphics and more features... so it seemed!
i erased the hdd and installed Leopard, which i had purchased for my Macbook, but decided to hold till i got this...
install went smoothly and got into OS and did the update center... started downloading... fine.... went and got a coffee... came back.... still on the first file of the update donwload.. hmmmmm weird.. normally be halfway or finished by now! i checked the wireless and noticed the send/receive was just hanging.. *not disconnected from the wireless router..* anyway i decided to hard reset the router and let it reconnect so it was fresh.. connected fine... started donwloading again.. same happened... anyway i left it donwload and do its stuff as i saw there was a key chain update which resolved some wireless issues.. great i thought.. Apple must have seen there is a problem and fixed it.. yay!!.......... heck no!
rebooted the laptop after install was done... SAME problem... not only that... i couldnt be on iChat/MSN for more than 5-10 minutes before it decided that it was going to fall asleep and stop doing anything before realizing that ****... someone is still wanting some connectivity.... by that time its disconnected/timed out from server/webpages... Webpages take about 15-30 seconds to load on intermitent basis...
Next is the bandwidth... i usually download between 180-205kb/s in Tiger on Macbook... in leopard im lucky to break the 100kb/s barrier for more than 30 seconds before it goes to 10-30kb/second!!!!!!!!! and upload speed is killed too!!!
i have read through various threads on the boards and have entered different tcp/rwin commands and turned off ipv6 in wireless but still same happens... no airport2 file either to remove..
i'm really annoyed as it seems from wanting to go to a better laptop ive only gone and brought defective hardware which i dont understand why Apple didn't test this prior to release
FIX IT quick please, i feel like taking this thing back... what use is it if i cant browse the internet which is a basic function on any laptop now a days yet vital it works!
maybe reinstalling Tiger is the only option left, there goes a weekend of installing programs/games/updates!!!!! annoyed

cheers for reply dude
will see how this gets on, also changed the channel to 6, see how that gets on..

seems ok?
Although RWIN TCP/IP analyzer seems to point out problems...
MTU = 1442
MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput. If you are using a router, it could be limiting your MTU regardless of Registry settings.
MSS = 1402

Default TCP Receive Window (RWIN) = 65330
RWIN Scaling (RFC1323) = 0 bits

For optimum performance, consider changing RWIN to a multiple of MSS.
Other RWIN values that might work well with your current MTU/MSS:

Help - tried to install leopard over tiger on iBook G4 and cannot boot up

My ibook G4 apparently does not have enough disk space to enable me to install leopard; shame, BUT in process of finding this out I cannot restart in Tiger - machine spends 3-4 mins trying then powers down to black screen.
Any help/advice gratefully received...
Thanks, Bob

Hi Bob, and a warm welcome to the forums!
Do you have a Backup?
Do you have a bootable external drive?
Do you have another Mac around so you could use FW Target Mode to clear some space...
http://docs.info.apple.com/article.html?artnum=58583
If none of the above, then using your Install Disk to Erase everything and start over completely is about the only ting left.
Due to temporary files, RAM Discs, VM, you need twice what they say minimum to install... 20 GB free.

How do I source install media to upgrade from Tiger 10.4.11 to Leopard 10.5

My aim is to upgrade my macbook to snow leopard 10.6 from Tiger 10.4. I bought the media for 10.6 but didn't realise that my macbook should be at a minimum of OS X 10.5 to be able to upgrade to Snow Leopard.
Does anyone know if 10.5 upgrade media is still available?
My Macbook has a 1.81Ghz Intel Core 2 Duo processor and 1GB Ram, is that enough for Snow Leopard? Anyone else in this situation?
Any help and advice is welcome. Thanks in advance.

Hi hdereland, and a warm welcome to the forums!
Does anyone know if 10.5 upgrade media is still available?
You have to call Apple to see if they still have it available, the Stores no longer have it.
My aim is to upgrade my macbook to snow leopard 10.6 from Tiger 10.4.
Many just install it anyway from 10.4

De-installing Leopard and re-installing Tiger

After installing Leopard, my Final Cut Express won't work, so I want to de-install Leopard and Quick time 7 and re-install Tiger and earlier versions of Q Time. Do I do this?

By erasing your hard drive then reinstalling Tiger and all required updates. Be sure to backup your files first so they can be restored after the reinstallation.

Disk Warrior 4.0. Can I install it on Leopard to use on Tiger disk?

Hi,
I have a Mac Pro with 2 boot disks, 1 Leopard and the other Tiger. Can I install Disk Warrior V4.0 on my Leopard volume then boot into Leopard to use DW to diagnose/repair my Tiger volume... which is the one I still use? I had heard V4.0 was not Leopard compatible... but I am not sure if that means you can't run DW V4.0 from a Leopard volume or just not to repair a Leopard volume.

Nothing, or buy a new iPhone. Your 3G cannot use iCloud, which you need for Find My iPhone.

Best way to clone Tiger before installing Leopard

OK, so I am ready to take the plunge. I want to back up my Tiger HD before installing Leopard but have some confusion about the best way to do this. I have Super Duper and a FireWire LaCie external HD with sufficient space to clone my Tiger system. However, there are other files on the LaCie and it is not partitioned. If I clone the Tiger HD to the LaCie, are all the other files going to be erased? Will the clone be bootable? Or should I transfer the files from the LaCie first, erase it, partition and reinstall the files on one partition and the Tiger HD on the other? Or should I clone to a disk image?
Thanks in advance.

that's one option. If you have enough space on the drive you can partition it on the fly without erasing the stuff first. I'm not sure if Tiger's disk utility can do that but leopard's certainly can. you can therefore boot from the leopard install DVd and do it from disk utility there.
Thanks in advance.

Install Leopard over tiger from cd, overwrite or update?

I want to install leopard on my macbook with tiger 10.4.8 from cd.
Can i install leopard from cd on my macbook without overwriting everything.
So when i install leopard over my tiger, will it overwrite everything else or will it update the os with all files and setttings in tact?

Hi gizeh12,
I'd recommend backing up (on an external HD, CD, DVD, thumb drive, etc) any important data. While the upgrade option is designed to preserve all of your data, settings and applications, Apple strongly recommends (as do many users on these boards) that you always maintain a current backup of your data. While the percentage is very small that you'll have a hardware or system failure during the upgrade, it's always better to be prepared then in panic mode.

Install Leopard over Tiger Server

Hi,
I want to "archive and install" Leopard over existing Tiger Server. Will not be installing the server version of Leopard, just the normal OS.
Are there potential problems (other than the usual suspects) with doing a simple "archive and install" over the existing Tiger --server-- OS? Can I just do new install without sinking the ship? (Fairly experienced w/macs, know the usual routine re OS installs but am shaky when it comes to server stuff)
Thanks,
Ron W.

Actually the Server version is only required if you are going to be backing up your server over the network. If you run Retrospect on the server itself, you can get by with the Workgroup edition. The developer has a chart that explains it all:
http://www.emcinsignia.com/products/smb/retroformac/comparison/
I don't recall the details, but I even think there was an upgrade path from the Desktop version to the Workgroup version, although I had to call the developer and specifically ask for it. Regardless, the prices aren't that bad. Check smalldog.
