https://forums.macrumors.com/thread...s-tolerating-osx-starting-with-tiger.2112845/ Good news everyone! More has come! A simple automated script has been built that optimizes Tiger out the wazoo! - - - - - - - - - - - - - - - - - - - - After an exhaustive amount of research and trial / error, I've devised a script that effectively combines our collective findings to increase performance on Tiger thus far that automatically disables Dashboard, removes AudioIPCDriver, all modem kexts, redundant frameworks, relevant libraries, etc. at the cost of rendering several seldom-used and already broken applications nonfunctional (i.e. Sherlock, iChat). From a fresh install, this results in a very noticeable speed increase in boot times, Finder operations, application launching, and other all-around usages. Not only that, I've noticed that it also may more than double uncached write speeds (unfortunately, this was not the case on my B/W G3), though other benchmarks remain largely unchanged. I've been testing the execution and aftermath on several machines for under a week now, and so far nothing has proved unstable or worse off since running it, but only more responsive overall. Theoretically, it should also work on Intel. 1.42ghz G4 Before: 1.42ghz G4 After: On a 400mhz G3, TenFourFox launch times have gone from roughly 30 seconds to 24 seconds. On a 1.42ghz G4, TenFourFox launch times have gone from roughly 20 seconds to 10 seconds. On a 2ghz G5, TenFourFox launch times have gone from roughly 10 seconds to 5 seconds. I've also included a reverser script that replaces everything TFT has removed, as long as the trimmings are exactly where TFT left them. Needless to say, I think this is the closest G3 machines will ever come to Snow Leopard, at least in terms of optimization and compatibility. (As a companion project, I've also made a custom prefs.js for Camino 2.1.2 specifically for speed and site compatibility; particularly useful for light G3 browsing.) - - - - - - - - - - - - - - - - - - - - TenFourTrim and the optimized Camino builds / prefs.js have been added to Macintosh Garden. They can both be found here: (http://macintoshgarden.org/apps/tenfourtrim) (http://macintoshgarden.org/apps/camino-212) Alternatively, I will also be offering TenFourTrim below as an attached file. Make sure to process the Read Me, as it contains all other relevant details. Note: There will be a much larger difference if running this after a fresh install as opposed to an already manually optimized install. Note 2: After running, please allow time for all of the system and application caches to regenerate, which for some configurations may sometimes take up to several days. Multiple reboots will not accomplish this, but sustained ordinary usage will. Thank you.
