Can I install Tiger on my iMac slot loader running OS 8.6?

I'm keen to upgrade my iMac DV bondi blue slotloader running OS 8.6 to Tiger so I can take advantage of wireless networking. Do I need, say, OS 9 first? or can I just go to Tiger directly.
Also - does anyone have experience of putting a new OS on an old machine - is it actually worth it or am I asking for trouble?

Hi Macnabbs,
yes, you can install Tiger on your computer. However, you will have to upgrade to at least 9.1 (better 9.2.1: ) before that, then upgrade your firmware and install at least 256 MB RAM (better: 512 MB). Also make sure you have at least 5 GB of free hard disk space! MacOS X needs a minimum of 1.5 GB of free hard disk space at all times in order to run properly.
The short version goes like this:
0. Confirm your Mac meets the minimum hardware requirements: Built-In firewire, 256 MB RAM (512 MB recommended), 5 GB free hard disk space (System Requirements)
1. Update to 9.2.x: Mac OS 9: Available Updates
2. Upgrade your firmware: Mac OS X: Chart of Available Firmware Updates
3. Download the Mac OS X Update 10.4.5 Combo update: Mac OS X Update 10.4.5 Combo
4. Unplug all peripherals but the original Apple keyboard and mouse.
5. Install Tiger
6. Repair permissions before and after an update!
7. Apply the 10.4.5 Update
8. Repair permissions before and after an update!
9. Run software update from the Apple menu.
10. Repair permissions!
Keep the order!
If you cannot select your hard disk as a destination volume and your computer is quite old this article might help:

Can't install OS 9 onto G3 slot loading - have restore cd with oS 9.0 only

I am trying to update my G3 to OS X. I purchased OS 10.0.3, OS 10.1 update and OS 10.1.5 update plus other stuff. I successfully got it all working, airport and all but had when I installed one of the updates I had to install and erase. It therefore wiped out my OS 9.2.2 that I had. Then I tried to re-install my OS9 (my machine only came with OS 9.0 restore cd) and an article I read on how to install it recommended I do a "clean install". After many, many hours of upgrading... I lost all of what I did to upgrade to OS10. NOW, I can't install OS 9! It tells me it can't install the OS9 system folder on the destination disk... What do I do? I don't want to have to start over again!!! It also won't recognize my airport card now! HELP!

Installing Tiger to a iMac G3-700 SE

Hi everbody,
Recently purchased a DualCore G5 2GHz. Awesome machine. It came with pre-installed Tiger OS. I'd like to upgrade my older computer as well. Therefore I have a few questions, all help is highly appreciated.
1: Can I install Tiger to an iMac G3-700? Or is there a minium hardware requirement?
2: I assume Tiger installer CD is a DVD-Rom. Therefore my iMac was not able to read it. Is there any other way to use the installer CD toward older computers without DVD reading capabilities? What if I cpoy the installer CDs to an externa hard drive, can I run the install from there?
3: Do you think an iMac G3-700 (512mb ram) would be too slow on Tiger OS?
Thanks in advance!

Mac OS X Version 10.4 requires a Macintosh with:
PowerPC G3, G4, or G5 processor
Built-in FireWire
At least 256MB of physical RAM
A built-in display or a display connected to an Apple-supplied video card supported by your computer
At least 3.0 GB of available space on your hard drive; 4GB of disk space if you install XCode 2 developer tools
DVD drive for installation (get CD media for $9.95)
The Tiger retail install package and the Tiger install package that ships with a new Mac purchased is on DVD media.
The Tiger install package that ships with a new Mac purchase is model and system configuration specific and cannot be used to install Tiger on another Mac model. If this were possible, it would be a violation of the single user license agreement that you agreed to and against the law.
If your iMac meets all other minimum system requirements except for having a DVD drive, purchase the Tiger retail install package and if the iMac is capable of Firewire Target Disk mode, you can connect your old and new Mac together this way to install the Tiger retail install package on the iMac.
If not, you can use Apple's Media Exchange Program to exchange the Tiger retail DVD media for CD media.

Can you install tiger on a power mac g4 with out a DVD drive if so how, I do have have a 2011 iMac can I use that in target disk mode with a FireWire cable any help would be appreciated

Hello,
You need to put the Tiger Install Disc in the 2011 iMac, boot the 2011 uMac into Target mode...
http://support.apple.com/kb/HT1661
Boot the G4 holding the Option or alt key, hopefully the Install Disc in the 2011 iMac will show as a boot choice.
We just want to use the 2011 iMac as a big expensive FW Optical drive, it cannot be installed osing the 2011 iMac itself.

Can I install Tiger in my NEW 21.5" iMac ?

Can I install Tiger on my NEW 21.5" iMac ?
Machine bought new - Nov. '09.
While I do like some of the features in Snow Leopard... almost all my existing software plus the Sims 2
games will apparently NOT run (or run well).

Rosetta does exactly that. It was created to run MacOS X programs that only ran on PPC macs to run on intel processors. Rosetta would translate PPC machine instructions into intel instrucions on-the fly.
Classic Mode was a whole separate operating system. Rosetta merely translates PPC to intel so it is generally invisible to the user.
I have used Quicken '05, iMovie HD, AppleWorks and Microsoft Office under Rosetta with no issues. Photoshop 7 was the only program I have that choked and would not run. I would guess that the Sims program would be most likely to not run. They might have an intel update available, I know that Zoo tycoon 2 had a patch to allow for intel processers, The Sims might, too.
Some programs have "fat binaries" with both versions. If you are curious, you can see whether you are running intel or PPC-translated by using the activity monitor.
You don't need to run Rosetta separately, if it is needed it turns itself on, so the programs install normally. In fact, some programs needed Rosetta just to run the installer, the actual software ran on the intels.
I think I have the same machine as you, I just bought my new 21.5" iMac last month. I love it by they way, a DVD that would have taken all night to burn was done in a little over an hour!

Re-installing 10.2 on Blue iMac slot-load

About a year ago, I converted a slot-loading blue iMac from OS 9.2 to 10.2 with a legal set of disks. I went through the upgrades to get to 10.2.8. Lots of great music on iTunes!
Suddenly it won't even boot. An Apple Store guy suggested I boot from the OSX.2 disk and do a "clean install" (or something like that).
Did that, but can't get any of the upgrades to unstuff. It tells me that Diskcopy has an error. Help won't work at all.
Also, what is with the new folder called "Previous Systems?"
Hopefully, one of you smart people can send me in the right direction because I'm too frustrated to think straight.

Trouble installing tiger on an iMac DV+

I tried installing new Tiger software on an iMac DV+. When I click on the Install Mac OS X icon in the installation folder, I get the following message: "Mac OS X cannot be installed on this computer. Please consult the documentation for the list of supported computers."
My computer should be supported. I'm currently running OS 9.0. I found some info online that said that I have to upgrade to 9.1 and then do a FirmWare update 4.1.9 before I can then install Tiger. Well, I upgraded to 9.1 and then tried to do the FirmWare update, but I think the Firmware update will only work if you have a CD for it in your CD/DVD drive.
Does this all sound right? Do i really have to get a FirmWare disk before I can do all of this? It sems so circuitous and roundabout. I'll spend more money, but I want to be sure first.
Can anyone help me?

You do not need a firmware CD to run the firmware updater on your iMac.

IMac Slot Loader Problems Upgrading from os 9 to Tiger

I have an iMac Slot loader that i want to bring up to tiger. The firmware is at 4.1.9, it runs panther fine, but when i install Tiger via Firewire it freezes on the reboot.

ok. I did everything that the reference document told me to do. The onl thing i get now is a Gray screen with the startup music that u get when you get ready to setup tiger. The firmware is up to date i know that i checked it before starting the install. I have gotten rid of all third party ram and still that is all i get i am so lost and confused on this one. I am about ready to give it the parking lot slide. Anyway thanks for the help but we are closer but close doesnt count except for in horse shoes, hand grenades, and atom bombs.

Can't install tiger v. 10.4 please help!

I may be being incredibly stupid here but how I am supposed to install Tiger if my iMac doesn't have a dvd drive?? I currently run OS v.10.2 and need to upgrade, I bought Tiger and now I find I can't install it because I can't run the installation DVD! Surely there must be a way around this which doesn't involve me paying out for a DVD drive. If anyone can offer me any help if would be much appreciated!
Many Thanks,
Linsey

Hi,
you can exchange your DVD for installation CDs. I'd call Apple to get that done. Since we don't have Apple Stores around here I don't know if you could also go there and have your media exchanged. Alternatively you can hook up a DVD-equipped Mac via Target Disk Mode and install it that way.

Can you install Tiger onto a drive with data?

Hello,
I would like to ask if you can install Tiger onto a hard drive that already has data files on it. I have a 250 GIG hard drive and it already has 10 GIGs of data on it. Can I install Tiger on this drive or might it corrupt my files?
Its a long story but here is a quick summary of why I am attempting to do this:
I have a 350 MHz Blue and white G3 (rev 1) with two hard drives: the original 12 GIG ATA drive and a 250 GIG SATA drive (internal) connected with a 1S2 Seritek SATA controller.
My 250 GIG drive has two partitions but only one is available to Tiger. You see, by accident I originally formatted my 250 GIG drive with an extremely small partion (32 Megs). I meant to type "30 GIGs" and by accident I typed "30 Megs". Oops That was supposed to be my OSX 10.4 volume. Its too late now - its too small. So I only have two choices for a place for TIger: my 12 GIG drive or the other partition of my 250 GIG drive. I am reluctant to choose my 12 GIG drive because it already has an older OS on it (OS 8.6).
I was concerned about installing TIger on the data partition of the 250 GIG drive because that is where all my valuable data files are - 10 Gigs of data. I don't want to risk scrambling this data in any way.
Is it safe to install Tiger onto this partition with my data files? Or is the possibility it might do something to my data.
Its only a temporary install so that I could burn my 10 GIGs of data files to DVD for backup and then I will start all over again and erase the entire hard drive and reinstall from scratch onto the 250 GIG drive once my data files are safely backed up. (I will not partition the 250 GIG drive i nthe final install - it will be one big partition.)
One other question:
When you format a disk in Tiger are there options to "low level format" or "zero all data" or will just a straight "erase" do the job sufficiently? I bought my 250 GIG Hitachi SATA drive new and so I am not sure if it worth the time to re-erase it with "zero all data" (if that is an option in the Tiger Disk Utility). What is the best formatting option to prepare this drive in the most beneficial for Tiger?
Thanks for any suggestions.

Thanks scb and Jeff,
Jeff, you have me thinking now. I think I will be safe and try another idea. I have a 4 GIG internal SCSI drive I could use to backup my data in 4 GIG sections at a time via my Adaptec 2430 SCSI card. I could then move this hard drive over to my other G3 onto its 40 GIG hard drive. This would be done three times to take off all my data and essentially provide a backup before I install Tiger. Good idea. You are right. It is better to play it safe.
By the way 8.6 can handle HFS+. And yes, I should eventually buy an external drive solution - probably an enclosure. I saw one called "coolmax" [1]. It could hold a SATA drive and it had USB, firewire and also an external SATA port.
And also Jef thanks for the info about formatting drives. I am glad to hear it is not important to zero all data if you don't have to. I am not concerned about havig anything to hide and so yes, I will just click "format" - that should be fine. Zero all data takes such a long time and I would rather avoid using it if I don't need this feature. Thanks for the advice.
Thanks for the new safer direction.

Can I install Tiger in a Dual 500 MHz PowerPC G4?

Can I install Tiger in a Dual 500 MHz PowerPC G4, or is it better to stick with 10.3.9? I'm having some problems so I was going to wipe he hard drive and re-build everything from scratch o I was wondering if migrating to OS X 10.4.9 is worthwhile or even compatible with this PCU. Thanks.

Yes you can run 10.4 on your dual 500, I have a dual 450 (I overclocked it to 550...) and it runs pretty fast. You need a minimum 192 MB of RAM to install it and a minimum 128 MB of RAM to run it. I would suggest having at least 512 MB of RAM when running 10.4.
What problems are you experiencing? If it's just lagging and seeming slow it may just be worthwhile to clean some temp files and clean up your disk. IMHO, 10.4 is a much better system than 10.3, and runs much smoother. I can guarantee you that your system will run much smoother if you wipe the disk clean and put a fresh install of 10.4 on there, and also get a decent amount of RAM in there. After I upgraded my RAM to 1.5 GB, I noticed a substantial difference in speed, and got a lot less spinning color wheels. But one thing that you need to always keep in mind is to KEEP YOUR DISK CLEAN!!! Clean the temp files often and limit your internet downloading. If you keep your computer on all of the time, restart it every once in a while. There's a lot of little things you can do to increase speed in OS 10.4. Use spotlight and recent applications. Fill up your dock. Don't clutter the desktop, etc. There's plenty of articles on the net to help increase speed without adding anything else to your system, just navigating through the OS differently.

Can I install Tiger on Mac OS X 10.6.2 Snow Leopard?

I am using Mac mini and my OS version MAC OS X 10.6.2 Snow leopard and it was as default with my Mac mini,
Can I install Tiger 10.4 on my current Mac mini in different location as dual boot?

Welcome to Apple Discussions!
No Mac can install an older Mac operating system than shipped with it.
The only minor exception is Macs which shipped with Mac OS 9 and Mac OS X, but those ones only could run the Mac OS 9 that came with it and newer one, and Mac OS X that came with it and newer one up to the limitations of the hardware.
Also no Mac can install an operating system disc from a different Mac that is different either in model or vintage.
If you are missing compatibility with your new Mac Mini for a specific application, please check
