System software from Tiger can be run in Leopard. Faster?

[vddrnnr]

Hi all,

Yesterday I tried running some software from OSX Tiger in Leopard ( Terminal ).
It runs very well and it seemed faster and looks more or less the same.
Has anyone tried running other software from Tiger?

Hi all,

A quick update.
System Preferences Run and DVD Player also runs.

On a side note I did a CPU load comparison while playing a DVD in Tiger and Leopard
and a PB-G4 1.25Ghz plays a DVD with less CPU load on Tiger than a DLSD on Leopard.
Any Ideas?

I've never shaken the notion that every process under Leopard is slightly more demanding because the OS was written and optimised for Intel?

Leopard is a more complex system. It has more overhead, so Tiger will always run faster.

If Tiger is your thing, run Tiger. For myself, I only run it on systems that can't run Leopard. Leopard is far more robust than Tiger and I depend on that as well as it's ability to run later versions of apps.

I don't believe that to be the case, although I may be wrong. I see it as Leopard simply being more complex because features were added or improved.

Which is definitely the case but there was a huge system requirement increase between Tiger and Leopard.
Between Puma and Tiger, still worked on G3 needed 256Mb instead of 128Mb.
Between Tiger and Leopard, minimum 867GHz G4 and 512Mb plus ideally Core Image GPU.
I know Leopard can function on less but just going with the official figures.

I used to run Panther's system prefs in Tiger all time, I liked the customizable top section. I don't think Panther's will work in Leopard though.

Hi all,

Been tinkering a little more with DVD player in Leopard.
Now it's running with Tiger's DVD Playback and DVD frameworks copied from a tiger install.
Load is definetelly lower ( +- 5 plus percent ).
Unfortunatelly DVD Player from Leopard complains about missing symbols.
I've also "copied" most of the artwork from the leopard version so it's looking like this.

I'm wondering why you don't just run Tiger?

Is there some feature or part of Leopard you can't go without that Tiger doesn't have?

Hi eyoungren,

I'm just trying to optimize the system using less CPU hungry apps but still
retaining the Leopard "Looks" and functionality.
By using this version and it's frameworks ( it plays DVDs just like the Leopard version ) but my
temps are lower and fan speed is also lower so overall a better experience

My idea is that maybe we can have other software/libraries from Tiger that do not
affect the system so much and so we may have the best of both worlds for our systems.

Gee..reading this has got me wondering if I should re-install tiger on my ibook G4..and have another try. Been a while since Ive used tiger.

Or maybe even - get Tiger's UI running on top of Leopard. ?

Hi all,

From my testing there seems to be two factors in this equasion.

1. Tiger and maybe the early Leopard builds seem to be more optimized for powerpc hardware.
That's why I think in Leopard Tigers DVD Player using Tiger's frameworks use lowec CPU ( not comparable to tiger
running the same app, but still a reasonable improvement ). In the case of DVD Player you also get a bonus because
the version from Tiger as a vertical mode if you prefer it.
2. Leopard without a dought is eavier than tiger so it performs worst in powerpc hardware which is not uptodate
with the OS requirements especially in the later builds.

PS. One of the things I had already noticed when I started iusing PPC Macs two years ago is that the last
security update is a performance killer and I do not install it on any powerbook I have.

@eyoungren
. I do want to keep using Leopard as it is a superior OS in functionality more uptodate and also offcourse
the available software.
. I also need spaces to keep my daily workflow so out of the box I need Leopard.
. I am also a sucker for looks and for me Leopard "loloks better" ( IMHO ) .

Very cool stuff you're uncovering, void.

What is this last security update, and what does it do, if you know? Could it fulfill the same purpose as AudioIPCDriver.kext, and do you think the same exists for Tiger, or perhaps other versions as well?

I am not surprised at these findings. Fits right in line with how Apple thinks and does.

Hi Z,

The security update is the one that shows on software update the 2011-004.
I noticed it first when I installed it on my PBG4 12inch 1.5Ghz it started playing youtube videos
slower and system seemed less quick.
I reinstalled the PB again and just left the 10.5.8 combo update and it seems faster.

I also found this link posted here on macrumors ( it's from 2018 I think you might have
seen it already ).
