I forget where I downloaded that 4L5 update but I ended up reburning my drive. It did improve responsiveness on my B&W G3 400/ 384MB...but....it also seemed to make it more unstable. I wasn't really experiencing regular kernal panics until I installed that.
My thought is that if Apple hasn't released it by now (a week later) then it is probably a beta or there were things to be fixed befored release.
VGZ made it sound like 4L7 has been released, it hasn't. 4L7 is another illegally circulated update off of Carracho. My god man, we don't even know if it really came from Apple... but hey, as long as you are taking the risks, feel free to tell me exactly what it did/did not do for your system... =)
Well, it worked, and I have not expirienced any dificulties, but I can't say I have noticed any differences either. On the other hand I have not even expirienced any of the dificulties that a large number of people are complaining about either. Maybe I am just blessed.
These are leaked internal builds. I don't mind installing them but I always back-up my computer before hand and test to make sure everything still works. Be very careful if you are going to install one of these builds. I don't mind breaking my system because I like to mess with it and I have a backup to use if it breaks.
Software Update won't show the update on the updates list if you already have installed earlier builds of the update, because it recognizes your OS as already up to date.
So here's how to install the update over older updates:
Simply delete the 10.0.1Update.pkg file located in >Library>Receipts. Remember to empty the trash. You may have to boot into OS 9 to do this.
