Essentially, the payoff for doing all those things wouldn't exceed the consequence. Many people make use of Dashboard, Spotlight, and the others (myself included). If the script disabled them, the usual reaction would just be to undo the changes, in the process bypassing everything else being offered.

And Dashboard isn't even using any resources at all if you simply do not open it. If you do, the widget DashQuit is very useful for actually quitting back out of it.

Believe me, I've already pondered this road during development...

Yes, the things I mentioned shouldn’t be enabled for everyone by default. I use spotlight a lot too by the way.

Thanks
 
Hi everyone! It's fantastic to watch this community work--truly one of the most dedicated and successful I have ever seen in developing for any platform. And of course, thank you so much to @z970mp for this tremendous work in making Mac OS slimming easy.

Thinking about which OS to install on my newly-acquired PB G4 12 inc (1.5 Ghz), and without trying to reignite the whole Tiger vs. Leopard thing...how much of an improvement in UI responsiveness does this add to Leopard? I prefer the look of Leopard, but I always found it to be draggy compared to Tiger. If this patch gets that difference close, might reinstall Leopard. I also understand @z970mp has a version for Tiger, too.

Thanks again!

Hi @sheich0608,

Others can chime in on what their post-Trim experiences are, but I've personally seen a great performance achievement on all the machines I've run these scripts on... otherwise I wouldn't have released them. ;)

Mainly, AuroraTrim will cut out useless kernel extensions that eat background CPU and memory bandwidth, irrelevant libraries, seldom-used fonts that contribute to long application launch times (TenFourFox in particular), and frameworks of applications that Apple has eventually rendered useless, like MobileMe, and Software Update. It also removes redundant debug files that Apple let slip during release, unnecessarily bloating the operating system. So, at absolute minimal, it WILL cut down on used disk space.

AuroraAccelerator will more-so enable advanced features and graphic drawing capabilities, kind of like the scripts that come with Leopard WebKit. It's this script that will do the heavy lifting for improved graphical responsiveness.

And AquaTrim / AquaAccelerator follow the same concept as closely as possible, yes.

I have the same PowerBook, though it's currently in an out of service state. If I recall correctly, the FX 5200 Go it ships with does not support a critical instruction that Core Image requires to operate to its fullest, thereby decreasing performance while still being "supported". So, keep in mind that may play a part during its experience of Leopard.

Hope I was helpful.

Is there anything that is known to break with the installation of this? I know you said that you designed this to be lower-risk than AquaTrim, but I am still curious.
 
@RogerWilco6502 The only things tested to break are built-in applications that Apple has already made unusable due to discontinuation and lack of support, all detailed in the Read Me.

Back when AquaTrim was first released as TenFourTrim, there were a very small amount of fringe kinks to work out, which has since been dealt with through minor updates. AuroraTrim came out after this, so it had time to improve on TenFourTrim, right out of the gate.

Right now, both AquaTrim and AuroraTrim are equally safe. But if for whatever reason the user has second thoughts, they are provided an Undo script, restoring everything back to the exact original configuration.

If you like what's offered here, you may enjoy what I've also archived to Macintosh Garden...

 
AuroraTrimcelerator has been updated to version 1.1.

Alongside a minor rebranding of both scripts to avoid confusion, they have also received a massive consistency improvement within the Read Me, Trimmer, and Accelerator. The New Courier font has also been removed from AuroraTrim's trim list.

All of the above changes have been mirrored in AquaTrimcelerator as well.

Cool idea to trim down Leopard and get rid of the intel stuff in it. Also, the QuartzGL optimizations are a good accelerator if the graphics card supports it by HW.

I´m in the process of doing the reverse: Bringing up Snow Leo (10.6.) to PPC in an optimized way, combining the early build(s) from SL with the PPC components of Leopard that are newer in 10.5.8 than in those dev builds of Snow Leo that actually _do_ run on PPC quite fine!

See here to get more info!
 
Monolingual trims out the Intel code, which is a recommended follow up to AuroraTrimcelerator.

The Trimcelerators remove extra fonts (which shortens application launch times), remove extra kexts (which saves memory bandwidth and idle CPU usage), and several other things which accelerate overall system performance.

No code tampering.

Is there any way I can apply the undo script if I have the files deleted? More specifically I'm looking to restore Software Update so that I can download updates for iLife.
 
@SKStrategia06 Unfortunately, no. This is why both the Read Me and the script explicitly require a fully updated system, so that the user doesn't need Software Update, and then have to face this problem.

If the trimmed files have been deleted (short of me offering the gigabyte-sized file here), you can either reinstall Leopard, or simply download the necessary iLife updates from Macintosh Garden, and then install them that way.

What I usually like to do is make a folder on my desktop to put all necessary files in, so that I can retain the data, and still have a clean desktop. Maybe this method could be useful to you going forward?
 
Hi @z970mp

There's an correct order to execute the scripts? Any other advice of in what part of a new Leopard installation to run each or both? There's any need to execute any of the scripts after some period of time? Thanks!
 
@dextructor Not really. You can execute them in any order you like.

However, I would actually recommend to you now to leave AuroraTrim alone and maybe just run the Accelerator. Once I've finished redesigning AquaTrimcelerator (not too much longer now), I'll move over to AuroraTrimcelerator and re-do that, which shouldn't take as long, given how the new base standards would have already been established with the redesigned AquaTrimcelerator.

And don't worry, there is no need to execute the scripts after any length of time. It's one and done.

Well, it's finally here. After two months+ of development, TenFiveTrim is ready for action.

AuroraTrim is an automated script that will slim down and optimize Mac OS X Leopard, removing redundant extensions, frameworks, fonts, and libraries that result in a faster and more responsive system.

It, combined with AuroraAccelerator, will probably be the closest to Snow Leopard PowerPC machines will ever get. And theoretically, it should also run on Intel machines without issue. However, a reverse script called 'Undo AuroraTrim' is also included that will restore all changes AuroraTrim has made back to the default, as long as the removed items are just where the script has left them.

AuroraTrim fills the same role as AquaTrim, while the new AuroraAccelerator enables advanced graphics APIs like QuartzGL for faster graphical performance, being especially noticeable if your GPU is Core Image-enabled.

Together, it will very likely be the closest Leopard ever comes to 10.6's speeds and optimizations, bar none.

AuroraTrimcelerator is available below.

Isn't there a program like this already called: Leopard PowerPC without intel code ? Samething ?

If anyone would like to get involved: Can somebody help me figure out a way to get mdworker to stop automatically starting upon initialization? Disabling the Spotlight and MDS .plist files as commonly referenced on the Internet, in addition to disabling every other Spotlight-relevant file does not work, and not to mention does not remove the menu bar icon as it does on Tiger.
 
Leopard has no future sadly. As I said, if PPC is to live on it must look towards ARM with universal binaries, or Linux, but it also has to be optimized to run much better than it does now.
