Themes... a la Extras.rsrc
Okay first off I use the AlumiteX theme... futuristic, easy to look at, very functional and intuitive to me as far as that goes. Get it here:
http://www.stretch.tc/aquaworld/themes/themes.html
now for those of you who have tried apps like Duality or Themer, etc. Stop. They have corrupted many peoples systems and it can be a real pain to get everything back to normal without reinstalling your system.
Follow this tip from a poster at Versiontracker instead.
" I beg you DO NOT DOWNLOAD THIS APP (Themer:Anche)... instead do this: 1) Open Terminal application ... 2) Copy and paste this: "cp /System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HiToolbox.framework/Versions/A/Resources/Extras.rsrc ~/Documents" (without quotes) and press Enter. [This makes a copy of the Aqua Extras.rsrc file into your home's Documents folder. Keep it.] ... 3) Type "sudo cp" (without quotes) and a single space ... 4) Drag the new theme's Extras.rsrc file into the Terminal window and drop ... another space.. 5) Copy and paste this: "/System/Library/Frameworks/Carbon.framework/Versions/A/Frameworks/HiToolbox.framework/Versions/A/Resources" (without quotes) and press Enter ... 6) Enter your administrator password and press Enter ... 7) log out and log in , thank yourself and enjoy your new theme. To go back to Aqua repeat process using your saved Aqua copy of Extras.rsrc. "
It is a very simple and straight forward way to change your theme. Most importantly you know what you did and can undo it.
Barring that make sure to use a Backup utility before you switch themes with shareware/freeware.
Personally Aqua was nice for a while and I may go back to it for Jaguar, just to see what Apple has done with it. Until then I love AlumiteX on my TiG4, it just looks and feels 'right'.
Finally, never underestimate the power of RAM. Fill your machine up with as much as possible. 2GB if you can. If your machine has a 133 mhz bus then make sure you get PC133 RAM, if not get the PC100 equivalent. When we get new Powermacs and Laptops with DDR support get as much of the fastest RAM you can. It really does make all the difference. Video RAM is just as important, especially in today's non-GPU accelerated world on OS X... Jaguar should change all this but until then and even after, get RAM.
Your hard disk is in the end the ultimate speed bottleneck. By the fastest Hard drive you can for your system. Store stuff on a big lumbering drive if you need space and can't afford speed, but buy a smaller 10 - 20 GB drive with a speed rating of 7200 RPMs or more for your OS install and with the fastest supported transfer rates, eg. ATA 100, 133, 166 where higher number is better.
All of these hardware considerations are OS agnostic. What works for a OS X works for Windows works for Solaris works for RedHat Linux.
Hardware is hardware and the faster it is the faster your OS will run. A Computer is made up of components so they all have to be fast for it to realize it's potential. This is what the X86/PC world has been getting for the last 2 years that we have been missing.
Our CPUs are great but the rest of the system is way behind. Response rates for a PC can be 4x as fast because their bus speeds are 2x as fast and their RAM speeds are 2x as fast, this is now standard and improving every month.
They get faster components because the manufacturers can recoup their investment in R & D by selling much larger quantities in a given time. Macs usually end up with a better product though because we get ours after the R & D has been perfected to allow for more efffective processes and higher quality returns, but we have to wait for it. This happens with all technology.
Strangely though Apple seems to be the company to innovate new tech while the PC world implements the performance improvement part much more rapidly.
God that was a long post. Oh well. I feel better for having put it out there after reading so much uneducated commentary.
