Downgrading from Tiger 10.4.11 to Panther 10.3.5?

So my old IMAC G5 (17in 512MB ram running Panther 10.3.9) recently had service at the apple store to replace the motherboard and the power supply. As a courtesy, they installed Tiger 10.4.11 when my computer shipped with disks for Panther 10.3.5.
While running the software updater, the OS update errored out and wouldn't restart from the apple menu. I had no choice but to do a cold restart which I knew would be bad. Now the computer boots past the gray screen with the turny gear and then the OS screen loads but the load bar doesn't load.
It's my assumption that I should reinstall the OS but without the retail Tiger disk I am screwed (since all I have is Panther). Any thoughts here on downgrading operating systems? I read all about it in the support section. I just want to know if anyone has actually done it and the thought of having to buy a retail Tiger version on ebay makes my blood boil (oh, that includes leopard too!) All the machine is being used for is leisure at this point, internet surfing and the like. Thoughts anyone?

Hi Karen, and a warm welcome to the forums!
Don't run the Panther's Disk Utility on the Tiger HDD, unless you want to erase things and go back to Panther.
Tough without the Install disc, but some things to try...
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...
http://docs.info.apple.com/article.html?artnum=106214
Tough without the Tiger Disk problems, but try fsck...
To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup. Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
2. At the command-line prompt, type /sbin/fsck -fy
(SPACE between fsck AND -fy important)
3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found: 
The volume (nameofvolume) appears to be OK  If fsck found issues and has altered, repaired, or fixed anything, it will display this message: *** FILE SYSTEM WAS MODIFIED ***   Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
http://docs.info.apple.com/article.html?artnum=106214
Then Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.

Upgrade Safari 1.2 to 1.3.1 after downgrade from Tiger to Panther

I wished to restore performance to my G3 iBook by downgrading from Tiger to Panther, and have been successful with that and have restored all apps to Panther versions except for Safari. The downgrade (archive and install) left Safari 2.0 on my HD for some reason, which of course wouldn't launch under 10.3.9. I dragged Safari 2 to the trash, downloaded Safari 1.2 which installed fine. However when I try to upgrade now to 1.3.1, I am told by the installer that the software cannot be used with the disc volume (the system volume) I choose to install to.
(BTW, invoking Software Update says my software is all up to date, even though I'm only on Safari 1.2.)
I've seen the other threads which have suggested removing Safari pkg receipts from /library/receipts, but this hasn't helped me in this case; I can't find any thread that had a successful resolution yet. Anything else anyone can suggest? Many thanks.

Mark:
Welcome to Apple Discussions.
You can try using Pacifist to extract Safari from your install disk and install it. You may then be able to upgrade it more easily, although I can't promise that for sure.
Unless you are absolutely wedded to Safari, I find Camino to be at least as good (I think better) as Safari, and looks almost identical, so that there should not be much of a learning curve. I also use Firefox and especially like it for the measure of security it provides.
Please do not hesitate to post back with further questions or comments.
Good luck.

Need to Downgrade from Tiger to Panther

I'm selling my iMac and need to downgrade it from Tiger to Panther, which originally came with the system. How do I go about doing this? In the process I also need to erase everything on my hard drive. Can I perform the downgrading from the original Panther installation cds, or erase the hard drive using those cds and reinstalling Panther from there?

Hello Kelly.
You need to backup all data first and use the Panther install package that shipped with this Mac and reformat the hard drive zeroing all data. Be sure to select HFS+ (or extended) with Journaling enabled when reformatting the hard drive. Instructions for zeroing all data included with this link.
http://docs.info.apple.com/article.html?artnum=107437
After doing so, re-install Panther and all software included with the Panther install package that shipped with this Mac when new. When completed, do not proceed with the computer setup assistant and shut down the computer.
When the buyer starts up the computer for the first time, he/she will be greeted with the computer setup assistant and you should include the Panther install package that shipped with this Mac as part of the sale.

Downgrade from Tiger to Panther?

Hi All,
Is it possible to downgrade a Tiger Server back to Panther? We upgraded to Tiger on one XServe to see if there were any issues. Because we have one lisence we need to downgrade that server so we can install Tiger on the good one.
TIA - Vijay

Archive and install is only for OS X Client.
If you really want to do this, the only way might be to export your OD Data using the "Archive" function in Server Admin. This puts the data in a format that looks just like when you do a command-line export of OD Data in Panther. You may be able to command-line import it to Panther Server. If you're interested in going with that, you can look up the info in the Server Documentation, or Apple Support files. I believe they have step-by-step instructions on command-line export/import of OD Data.
Besides the OD data, though... you're pretty much on your own. I don't know of a way to save all of your other services' settings.
Good luck.

Downgrading from Tiger to Panther

I installed Tiger on an old Powerbook about six months ago. Since then, it has been very noisy, and always seems to be gasping for life. The old powerbook is 867 mhz with about 640 ram -- not ideal specs for Tiger, I guess. My question then is -- how do I downgrade to Panther? Do I need to completely wipe everything off the computer before putting in the Panther discs? If anybody has any experience with downgrading, it would be great to know. Thanks.

You're welcome.
For quite a while though, I had been running it at less than
1 GB of disc space.
Copied from Problems from insufficient RAM and free hard disk space.
As a general rule of thumb: if the Available space on your Mac OS X startup disk is less than 5 GB, it is time to free some disk space. We suggest 5 GB as an absolute minimum as it generally requires that much free space to perform an Archive and Install of Mac OS X and still preserve some free space for VM swap files. However, more free space is better.
Although your Mac's specifications are plenty adequate for Tiger, this noise and potential hardware problem might be a coincidence that you are blaming on Tiger. Although most computer hardware can last a long time (especially Macs which is a factor in Apple's annual market share percentage for all computers sold since they generally don't need to be replaced as often as PCs), they don't last forever. It isn't a matter of if but when your hard drive has a partial or complete failure and although most don't experience a processor failure, it can occur.
Did a Hardware Test CD ship with this Mac when purchased? If so, I would boot the computer from the Hardware Test CD and run the Extended Tests to rule out a potential hardware problem.

Downgrading from tiger to 10.3.9. best way to do this ?

hello !
just got a new g5 dual 2.3 (not core) and i dont want anything to do with tiger ! (running lots of software that does not play nice with tigers..)
what is the best way to downgrade to 10.3.9 ?
thanks !

Hi csw, to "downgrade" to OS 10.3.9 you must first erase your entire drive, then install 10.3.x from the install disk and update to 10.3.9 with the 10.3.9 Stand Alone Combo Update
Do not use the disks that shipped with another Mac as these disks are model specific but rather the full retail Panther install disks.

Tiger/Panther install problems - won't boot from Tiger DVD or Panther CD

My Mum has an iMac G3 CRT, running at 500MHz, with 1GB RAM, a 20GB HD, & a slot-loading internal CD-RW.
The iMac in question is the model described here: http://www.everymac.com/systems/apple/imac/stats/imac500indigo.html
She only uses the machine for email & web browsing, but because it runs OS 9, it won't run a modern web browser (it's stuck on Internet Explorer 5.1.7) so lots of websites don't load properly or work at all. This is fair enough as IE for the Mac hasn't been updated since 2001.
My idea was to upgrade the machine from OS 9.2.2 to (ideally) 10.4.11, or failing that, 10.3.9, which would then let her use the current version of Safari, or possibly even Firefox. (Any thoughts on which would be easier for a currently IE-using technically-challenged pensioner would be welcome, although I prefer Safari myself, despite its shortcomings).
The iMac only had it's original 128MB of RAM until recently, but I persuaded her that it would be a good idea to spend 70-odd Pounds on 1GB of RAM so that OS X could not only be installed (which would let a modern browser be used) but would run at a useable speed. The minimum requirement for Panther is 128MB of RAM, but I suspected that it would run like treacle on a 128MB G3, and I was hoping to go for Tiger anyway, which requires 256MB.
As Tiger comes on a DVD (I have the retail/generic version) and the iMac has no DVD drive, I borrowed a friends external LaCie FireWire DVD-RW drive (the Porsche styled one). The DVD mounted first time, and the Startup Disk control panel let me select it.
When I restarted, I got the initial OS X pale grey screen with the dark grey Apple logo in the centre, with the spinning circle thing below, but after a minute or so, I could hear the DVD stop spinning in the drive, and a few seconds later the dark grey Apple logo changed into a dark grey "circle with a line through it" logo, with the normal circle thing still spinning below. This is how things stayed for many minutes, so I just restarted with the external drive off, and eventually got back to a normal 9.2.2 boot-up.
Next I tried running the "Mac OS X Install" application on the Tiger DVD from within 9.2.2. This started and came up with a big Tiger logo screen with a button labelled "Restart". Clicking it brought up an OS 9 error dialogue though, which said something along the lines of "the Tiger DVD cannot be selected as the startup disk" with a number 2 in brackets at the end of the error message - like this: (2)
This error occurs both if I select the Tiger DVD in the Startup Disk control panel prior to running the "Mac OS X Install" application, or if I select the internal hard disk. I know the DVD isn't faulty, as I used it to successfully boot my own Mac (a Power Mac G4 Mirror Drive Doors) just the other day, in order to repair permissions on the startup disk.
At this point I gave up on Tiger and tried to use the first of 3 Panther CDs that I have. These 3 CDs are burnt copies that came with my own Mac and contain version 10.3.2.
The CD refused to be selectable in the Startup Disk control panel. It's icon was greyed out, and so I couldn't boot from it. I tried running the "Install Mac OS X" application on the CD from within OS 9, but got the same error with the 2 in brackets when I clicked the "Restart" button, just like with the Tiger DVD.
Initially, I suspected that these Panther discs might be machine-specific, rather than the retail/generic version, because of the first CD being greyed-out in the Startup Disk control panel, but then the error dialogue that matched the one I got when I tried the Tiger DVD makes me think that my Panther CDs might be generic after all. Examining the first CD on my own Mac, it appears to be generic, but I'm not 100% sure, as the CDs are copies and as such don't have the usual identifying information on the labels. There are no machine-specific files that I can find on the first CD, which is dated January 9th 2004.
Various websites mention that when Tiger was current, Apple would swap a retail copy of the DVD for a set of CDs. I've looked on eBay but not been able to find any. This doesn't surprise me though, as there will be very few copies of Tiger on CD out there, and even fewer copies that people would want to sell.
There are a few retail copies of Panther available on CD, but if my current burnt copies of these discs are in fact generic, then buying a new set would make no difference. Besides, I'd prefer to use Tiger.
The Tiger minimum requirements (see http://support.apple.com/kb/HT1514) say:
"To use Mac OS X 10.4 Tiger, your Macintosh needs: DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation"
What it doesn't say though, is whether the DVD drive has to be an internal one with Apple firmware/modifications, or whether an external 3rd party one will do. However, I know from various websites that it's possible to load Tiger onto this sort of Mac, and sometimes even older non-FireWire Macs, despite what the minimum system requirements say.
If anyone has any suggestions I'd be much obliged!
Thanks.

The problem is now solved, but I'm not sure how I managed it, unfortunately.
Having read the article at http://docs.info.apple.com/article.html?artnum=75430, I checked both my Tiger DVD and my first Panther CD, and neither had the firmware updater on them, despite what the article said, so I downloaded it. However I was sure I'd applied a firmware update to the iMac a long time ago, and the 4.1.9 version number seemed familiar.
When I checked, I had in fact already applied the firmware update a few years ago!
I tried running the "Mac OS X Install" application on the Tiger DVD from within 9.2.2 again, and got the same error message as before. I was wrong about the error code though. It was minus 2 in brackets, not 2 in brackets.
The full text of the error message is:
An error occurred.
"Startup Disk was unable to select the
install CD as the startup disk. (-2)"
I tried selecting the DVD manually in the Startup Disk control panel (as before) and running the application again gave the same error message (also as before).
I then went into Extensions Manager to see if there was anything there that might be interfering with things. The only thing that caught my eye was the LaCie SilverLining control panel (which I think was version 6.4.5a). This was something that originally came on a floppy disk accompanying an external hard drive that I used to use years ago at a place I worked, and I used to find it invaluable back in the OS 9 G1 Power Mac magneto-optical external drive days!
I couldn't remember what it was doing on the iMac, but I switched it off, and then clicked "Restart", hoping that when I rebooted (in OS 9) the error message wouldn't come up when I ran the "Mac OS X Install" application.
However, I'd forgotten that I'd switched the Startup Disk control panel to the DVD, so when the iMac restarted, the initial OS X dark grey Apple logo screen appeared, and I expected the dark grey "circle with a line through it" logo to appear shortly afterwards, but it didn't! The iMac booted up from the DVD, which then let me install Tiger! I was then able to apply the 10.4.11 update, plus all the others that Software Update provided. About half a dozen restarts and several hours later, the iMac is now fully updated & configured, favourites are copied over to Safari 3.1.2, and all I have to do is teach my Mum how to use the OS X Finder, Mail & Safari, as opposed to the OS 9 Finder, Outlook Express & Internet Explorer...
Switching off the SilverLining control panel seemed to do the trick, but since the iMac then rebooted from the DVD, not the internal hard disk, I don't see how it could have possibly had any bearing on things! Very weird!
Anyway, thanks to Allan Jones & spudnuty for their advice. All's well that ends well!

Hi, I want to downgrade from OSX LEOPARD to OSX TIGER but I have a few questions regarding this. My iMac is originally from 2007 it came preloaded with tiger. I have original install tiger discs version 10.4.10. Is it safe to downgrade or not please help

Hi, I want to downgrade from OSX LEOPARD to OSX TIGER but I have a few questions regarding this. My iMac is originally from Sep 2007 it came preloaded with tiger. I have original install (2) tiger discs version 10.4.10. I want to know if it is safe and what are the necessary steps to do so. Also by downgrading im wondering if a lot of apps nowadays support tiger for example I have photoshop version 5 and 4 these are very important to me. One last question does anyone know of any reliable virus protection for mac that doesnt slow down your computer? because I have read that a lot of them do so. If anyone can help me I would greatly appreciate it! Here are the specs for my iMac

Most of the time a perception of general slow performance is the result of installing third party junk alleged to speed up, "clean" or "optimize" your Mac, or to look for viruses that don't exist. Ideally you would know what you installed so you can uninstall it, but if you don't know or aren't sure there are techniques such as Safe Mode and creating a temporary user account to confirm that suspicion.
If you open Activity Monitor it may show a process, or processes, that occupy a lot of your system's time.
Slowness confined solely to web browser activity is often the result of an inexorable progress toward websites that demand ever more processor-intensive tasks. If your slow performance is strictly limited to web browsing, you might try disabling Flash by either uninstalling it, or use utilities such as ClickToFlash that allow you to control what Flash content gets loaded. Flash in itself is not inherently evil, but there is nothing to stop websites or the advertisers who pay for them from writing horrible Flash code that can do everything from hogging 100% of your CPU's time to causing random crashes. You can watch Activity Monitor as in the above to correlate these troublesome web pages with performance degradation.
You are correct; if your computer shipped with Tiger you may certainly revert to it. I forgot that Tiger was shipping on new Macs as recently as five years ago. To downgrade it would be necessary to completely erase your hard disk and boot with the Tiger installation DVD, followed by installing it anew. Such drastic measures are not necessary and you are unlikely to be satisfied with the results anyway.
Assuming your system is free of third party parasitic junk attached to OS X in an ill-conceived attempt to improve upon it, that your hard disk drive is sound and the boot volume has enough free space to work with, by far the best performance-enhancing improvement would be to add more memory. Buy as much as your computer can use and that you can afford. 2 GB is not that much any more.

Downgrading to Tiger from Leopard on a mac mini 2.0ghz

I just purchased a mac mini 2.0ghz that came with Leopard.
Since I am relatively new to the MAC world, I assumed that I could immediately replace Leopard with Tiger on the HD using a set of mac mini install discs I had previously purchased on eBay (I'm doing this because this mini was going to be used exclusively to run ProTools - which isn't Leopard compatible)
From the little bit I've read, it looks like I may have made a $800 mistake. Most places are saying that it it absolutely impossible to downgrade from Leopard to Tiger on this late model.
Is that really true? I just find it so hard to believe that the hardware and software are so tied together that you can't ever go 'backward' even if you want to.
Could someone please state clearly once and for all if there is any possible way to downgrade or do I need to throw my new mac mini in the proverbial trash can and chalk this one up for the experience?
Thanks.

Welcome to Apple Discussions!
This issue was raised by another poster very recently (http://discussions.apple.com/thread.jspa?threadID=1497891&tstart=0). Typically Macs cannot be booted from MacOS versions which predated the release of the hardware, or subsequent firmware update perhaps, but since Leopard was not released until after the current Core 2 Duo minis, it goes without saying that at least some of these systems did in fact have Tiger installed.
If Apple have made no hardware or firmware changes to the mini (and it's a big if, because typically that information is not made available), then Tiger should install and run fine on your system, proving only that the Tiger installer you have is actually from a 'late 2007' Intel mini.
The only way you'll know is to insert the Tiger installer you have, and boot the system holding the C key down (you will need a wired USB keyboard which is NOT one of the new aluminium type). If the system boots, then you should be able to do an install. Bear in mind that you will almost certainly get an error stating you cannot install that version of MacOS on the system because it will detect that you have a later version of MacOS already installed than on the install disk. That's normal. You can get around that by clicking the 'options' button on the installer and selecting 'erase and install', which wipes the hard drive and installs MacOS.
If the system will not boot from the Tiger install disk, then in effect that would confirm that you will not be able to regress the macOS version - at least not by any conventional means. There are always some who investigate and find ways to work around some of these limitations, so there may be an unofficial and unsupported workaround out there, but there would be no way to know how stable it would be, and whether you would be able to successfully update it.

Downgrade from Leopard to Tiger after Built-In Keyboard Firmware Update?

Can I downgrade from Leopard to Tiger after having applied the Built-In Keyboard Firmware Update 1.0? This firmware update requires OS 10.5.2 or higher to be installed. Now that it is installed can I downgrade back to Tiger (10.4.11)?
I have a MacBook Pro 17 (late 2006). It ran perfect except for the occasional ignored first key press problem that these MacBook's have. In late December I upgraded to Leopard (10.5.6) and installed the Built-In Keyboard Firmware Update 1.0 that is suppose to fix the ignored first key press problem. Ever since then I have had constant keyboard & trackpad failures. When the built-in keyboard fails, thankfully I can still use an external USB or Bluetooth keyboard & mouse. I've tried everything. I've reinstalled Leopard four separate times, reset PRAM, reset SMU, repair permissions, pressure on the keyboard cable under the battery (even though I don't think this version of the MacBook has that problem). Nothing restored my internal keyboard and trackpad. During this process I tried to re-install the Built-In Keyboard Firmware Update using the original package file that I had downloaded, however I was given a message that the keyboard didn't need to be update because it already has the updated functionality and the installer package would then quit. Then I remembered that the original firmware update actually installed a Keyboard Firmware Update application in my Utilities Folder. When I ran the Firmware Update application in the Utilities Folder it instantly fixed my keyboard problem! Unfortunately the keyboard fix is not stable. It fails 2 to 3 time a week. Running the Keyboard Firmware Update application fixes the problem every single time, but this renders my MacBook useless as a portable (I have to have an external keyboard/mouse to run the Firmware application). I have, incidentally, tried all the other suggestions in the many keyboard threads in this forum (putting the computer to sleep, restarts, shut downs, PRAM & SMU resets, repairing permissions, running other applications, etc.), and nothing works except reinstalling the Keyboard Firmware Update using the application in the Utilities Folder. At this point I just want to downgrade to Tiger and go back to the way it was. I'll happily take the ignored first key press problem over a completely dead keyboard.
Please help.

Hi,
I was just wondering how you were able to get the macbook to accept the update? I had to take mine to apple store and get entire keyboard and trackpad replaced in my macbook. They then told me to ignore the update cause they did not have any other keyboards to replace if it happened again.

Installation from Tiger OS 10.4. back to Panther 10.3

I installed Tiger OS 10.4 from Panther 10.3 on my Desktop G4 Gigabit Ethernet 450 Dual because I liked to have it also on my Laptop G4 1 GB. Now I installed Panther OS 10.3 again but Wireless Internet doesn't work anymore. Why does it work with Tiger OS 10.4 but not with OS 10.3? I tried everything to get it work again but failled.
Thanks for any help
Adelbert

If there had been a related firmware update for the wireless system,
such a change could affect how an older OS X version sees it; if
that system was no longer able to administer the wireless network.
{And it may be, you could have to attempt to re-administer the wi-fi
base by Ethernet cable, in order to re-set it to work with 10.3.9.}
With a re-install of an older and more obsolete operating system,
there can be issues. Between the computing hardware, wireless
base station, and any other changes in the configuration due to an
upgrade to begin with, some of them may be harder to reverse if
they relate to a change in Firmware.
Presuming you have double checked all possible settings and have
an all new system 10.3.9 installed with no incorrect parts from 10.4
in there; & the Panther 10.3.9 also has been updated far as possible.
(There were updates in even the last few security updates, java update
+ other parts outside of the Combo 10.3.9 file, that could relate to wi-fi.)
Been a few years since I last dealt with Panther 10.3.9 and some wi-fi
and other issues; some troublesome issues related to a security update
file which had more than two possible remedies, short of a new full install.
Is the Panther install on a separate partition and if so, does the Tiger OS
still work correctly when running the computer from there? Or is the 10.3
installation a totally new from scratch install on a secure erased HDD?
The problem with asking a question, is that sometimes one invites more.
Good luck & happy computing!

Downgrade to Tiger from 10.5 w/ Windows partition

My Mac Mini came with Tiger, but I have since upgraded to Leopard. Leopard has been running slowly and I've been considering downgrading to Tiger. But, I'm worried about what might happen to my Windows partition. Will it be erased or will it even run at all?

First things first - there should be little appreciable difference in system performance between Tiger and Leopard, so unless you are running with minimal memory or running multiple applications, it might be worthwhile looking at why your system is running slowly under MacOS 10.5.x and try and resolve that rather than downgrade to Tiger.
That said, downgrading to Tiger is not difficult, and does not endanger your Windows partition. However, since you already have a later version of MacOS on the drive, you can't simply install an earlier one because the installer will baulk at doing so. You simply need to ensure that all your data is backed up, and then boot to the Tiger installer. Select the custom 'erase and install' option and ensure you pick the current MacOS partition to install onto. Once Tiger is installed, you'll get the same initial setup assistant that ran when the system was first put into service, and once you have completed that, you can install your software and restore your data from backup. As long as you do not repartition the drive, and ensure you direct the MacOS installer to the MacOS partition to erase and install on to, your Windows partition will not be affected.

Downgrade from Leopard to Tiger? Help please

I just got a new iMac that came with Leopard and I'm planning to use it soley for pro tools and pro tools isn't yet compatible with Leopard so I would like to downgrade to Tiger. How can I do this? I just ordered 10.4.8 for iMac's but am not sure if it will work or how to do it. I heard 10.4.10 disks work but have no way of getting a hold of them. Does anyone know where to get these or any that would work for a new iMac. And especially how to downgrade the operating system.

Well if you dig yourself a hole deep enough by not doing enough research, and then learn how deep you have to dig, do you quit and leave, or do you go all the way if you can afford it? The problem is Protools not following specs with software well enough to allow it to be compatible with Leopard. Maybe even ask the folks who make Protools to give you a discount on Windows because they can't write code fast enough. Or maybe now's the time to sell your Protools license and choose an alternative package like GVox Encore, or one of Apple's audio applications. There are a lot of good music software titles for the Mac if you search http://guide.apple.com/ thoroughly enough.
These are a good lessons to learn whenever buying a new Mac, or a new operating system:
1. Never expect to be able to downgrade a new Mac out of the box, as it has never been possible.
2. Research the software you intend to use before buying a new machine or operating system to find out if it is compatible with that machine's minimum operating system and within your budget. If it isn't that's the time to buy used or refurbished.
3. Buy what you need when you need it, and not before.

Downgrading from Leopard to Tiger, consequences

Because some apps don't function to well on Leopard, i need to downgrade to Tiger.
I have my old macbook cd-roms with Tiger, can i use those cd's to install Tiger on my Mac Pro?
Does downgrading have consequences for warrentee etc?

i have a macbook 2 GHz intel core duo, and i managed to get a copy of leopard and upgrade. but it made my computer really slow so i want to downgrade back to tiger (i still have my disks). i've been trying to figure it out and have read about archive and install, but when i try to do that the "preserve user settings" is not avaliable to choose. i also have my disc for microsoft office and i have kept my files backed up, but i am hesitant to erase and install. recommendations?
Erase and Install is the only safe way, but as long as you are going to the trouble, why not do the Erase and install with Snow Leopard? That should get rid of whatever was slowing Leopard. Make sure you get the latest , Snow Leopard compatible, versions of any applications you install.

Importing mailboxes from Tiger (Mail v. 2.1.3) to Panther (Mail v. 1.3.11)?

Is it possible to import mailboxes into Mail v. 1.3.11 running under Panther (10.3.9) that were originally created and stored in Mail v. 2.1.3 under Tiger (OSX 10.4)?
I have a dual boot Mac with Tiger and Panther running on separate drives; after moving over to Tiger I'm finding some incompatibilities with older software and want to move back to Panther permanently on this machine, hence I need to get all my latest mail folders back into the older version of Mail.
I've been sucessful in importing them, but they appeear as empty, and won't refresh even if I rebuild them.
Is there a way to do this?

Hi Jona,
Not sure if this is your situation but is it possible that it is a problem with Tiger's emlx format and Panther's mbox format? I'm confused though because you say that you were able to import them but they are just "empty" files.
See if emlx to mbox Converter - 1.0.3 can help. I have not used Tiger (I use Panther 10.3.9) so I am not sure that is your problem but worth looking at.
Just be careful to not delete anything before testing to make sure they have imported correctly!
If not a problem with format then perhaps with indexing.
good luck,
LS
