Would Tiger be available for G3?

At school there is a Blue G3 tower with Jaguar installed, i dont think its had any updates nor any work done to it as it is the hardrive is named My Computer. Its 450mhz and i think its got 380mb ram not sure. But even though its abit slow its still good enough to do stuff.
So i think tiger may run pretty alrightish on a G3 then
 
Basically it's like this: Ever since Mac OS X Public Beta, every update and upgrade to OS X has improved performance for any given Mac that officially supported the OS version. 10.2 was faster than 10.1, 10.3 was faster than 10.2 and 10.4 will be faster than 10.3.

There are specialised things in any of the OS versions that tend to be optimised for a certain processor generation. I bet there isn't much G3 optimisation going on in Tiger's development, but still _general_ PPC optimisation will let G3s become faster under Tiger, too.

Spotlight indexing is _at first_ a 'slow' process (from a user's viewpoint), since at first, everything has to be indexed. Once your Mac (be it a G3, G4 or a G5) has a working spotlight index, however, you won't notice much of a degradation. In fact, you simply won't. Maybe slow harddrives in older machines will try and make this noticeable, but I really guess that no, you won't notice it once the Spotlight index is built.
 
Why does/will Tiger require built-in Firewire? I have an iMac DV+ from around 2000 that has built-in Firewire. My sister has the base model iMac from that same generation, without Firewire. Does that mean Tiger will run on my iMac, but not hers? That seems very strange.

I'm very sorry to hear that the initial Spotlight indexing is automatic and unstoppable. That's going to kill a lot of people's first impressions if they don't change it. When I install Tiger, I know I'm not going to want to wait for however many hours to enjoy it. I'm gonna want to USE it for a good long while at 100% performance, then let it do its indexing while I sleep so I can play with Spotlight the next day.

I also have to wonder how big these indexes will be. If I don't have a whole lot of free disk space, is it going to crash and burn? I only have 8 free gigs right now, and I expect a lot of that to be taken up by Tiger itself.
 
No, Tiger won't take as much space, not for the index, anyway. Also: They just _can't_ let you enjoy spotlight before it's done indexing. They should maybe say so at installation time, would be better. But Spotlight's going to be a feature people want to enjoy about Tiger, so the first indexing is important. And when you try to access Spotlight while it does its first indexing, it tells the user what's happening, so that's good.

And about the G3 iMacs: That's been like that with Panther, too, IIRC. Built-in FW was a prerequisite for them, too. They _have_ to leave some old hardware behind, because if they just let the supported hardware list grow and grow, the amount of work to support all those machines in every OS release would grow too much. Plus: Jaguar's a fine system, too. (And they _do_ want you to buy a newer machine, of course. New, probably, serves them best.) ;)
 
What's this about needing built-in firewire to run Panther or Tiger??? :confused: I am running Panther on the original iMac G3 (no firewire) and it is fine. The only thing is I don't benefit from Open GL/Quartz Extreme, because the VRAM is capped at 6 MB. Likewise, according to Apple, Tiger will run on any Mac that currently supports OS X, just some older machines will not be able to take advantage CoreImage/Video. Still any Mac that does support Tiger at all will benefit from over-all performance tweaks. And the retail box of OS X 10.4 will be on CD, not DVD, according to Amazon.

Before Panther's release, word had it that older G3 Macs would not be able to handle it, that it would require a lot more RAM than Jaguar. Turned out that Panther actually made the most noticeable speed improvements in these older Macs, and did not use any more RAM than Jaguar. :)
 
Yeah, what do they know (amazon). ;)

Well, let me define "officially supported" differently, then. Goes like this:

Customer Support: "Tell me about your problem, sir..."

Customer: "Well, I've just installed Tiger on my bondi blue iMac, and..."

Customer Support: "I'm sorry to tell you, but Tiger is not officially supported on those machines anymore. You might find help on macosx.com, but chances are, they'll tell you the same."

;)

Just kidding. If it installs, it can also be supported. Not by Apple, though, probably.
 
I've had no problem's running Panther on my sister's 233mHz iMac. Sure, it's not exactly a dual 2.5Ghz G5 but it does the job.
i can't imagine Tiger being any different.
 
Sadly, Apple will at some point define in the code whether a system runs on a certain Mac, whether your sister likes it or not. It has already happened for some systems that were able to run Mac OS X Public Beta, 10.0 and 10.1 without a problem when Jaguar came out. There still was an unsupported way of installing Jaguar on those systems, but the older those Macs get, the less likely it is that their hardware will have any drivers left in the system's code.

How did you install it? I have a clamshell ibook 300 without fw (just 1 usb port), 6gb hd, 384mb ram and CD drive.
I first installed osx 10.1 on it. In a couple of months it crashed, and I decided to try some linux distros on it. First I tried Debian, and after some struggling everything went fine. Then I tried Ubuntu. Everything worked very well from the beggining. I even managed to make work my Longshine USB wifi adapter (after some compiling and modules tweaking).
After making a backup of both Debian and Ubuntu through the network with Ubuntu Live CD and partimage (so I will not have to install and tweak everything again), I decided to go back to osx again.
Now I'm on installing osx 10.3, but it's impossible, it freezes.
After the language sellection screen, when I hit the Continue button whatever language I choose, It hangs on the Wellcome screen (you can move the mouse, but nothing else works - I have to turn it off.
If I try to enter the Disk Utility instead of choosing a languaje, I get this error:
Error starting Disk Utility background process
Disk utility started, but a background process needed in Disk Utility didn't start properly. Please, quit and restart Disk Utility.
Maybe there's some problem with the ext3 partition?
I have tested the cds on other mac and they are ok. I even borrowed the installation cds from a friend, but I reached the same point.
I have tried to reset the PRAM with ALT+OPT+P+R, but same results.
Maybe I can't install osx 10.3??
Of course, I would prefer Tiger, but I'll update in some time.
