Two weeks ago, I bought a used 1.5GHz G4 mac mini. I swapped out the hard drive for a new 120GB 5400RPM Seagate and upgraded to 1GB RAM. Meanwhile, my iBook had gotten bogged down with a lot of apps I never use, so for the mac mini I decided to go ONLY with apps I will use for sure. What an opportunity! I did an install of OS X Tiger 10.4.2 from the installation discs that came with the mini - but I skipped all the printer drivers, since there were no drivers on it for the printer I use (Samsung). With all the apps I installed (including 3rd party) - my entire HDD uses only 3.51GB! Out of 111.8GB available - 3.51 GB used! How did I do it? First I used monoligual to get rid of all languages except the various flavors of English, French and Swedish. I also got rid of most keyboard layouts. And I got rid of the non-PPC frameworks and the G5 64 bit frameworks. Then I got very disciplined with software I installed - ONLY APPS that go on, are ones I'm sure to use, or which it's dangerous to uninstall without damaging some other functions of OS X. I did NOT install the iLife that came with it - sorry, I don't use iPhoto, iMovie (I use FCP 4.5 HD on my iBook instead), iWeb, iDVD (I got DVDSP on the iBook) or Garageband. I did NOT install any trialware or iWork etc. I updated to 10.4.10 using software update, but I also stripped out some OS X software I never use: Sherlock, iChat, Stickies, Chess, Nasaurus, Marble Blast, and some widgets, like: yellow pages, espn, snow report, stocks, clock, calculator, games etc. Then I installed the apps I knew I'd use (even if some I'd only use occasionally like MS Excel and Word from MS Office 2004). Here's my final list of apps: 1) Address Book 2) AppleScript 3) Automator 4) Bookit 5) Calculator 6) Dashboard 7) Dictionary 8) Disk Inventory X 9) DVD Player 10) Final Draft 11) Final Draft Tagger 12) Firefox 13) Flip4Mac 14) Font Book 15) Google Notifier 16) iCal 17) iDefrag 18) iGTD 19) Image Capture 20) info.xhead 21) Internet Connect 22) iSnip 23) iSync 24) iTunes 25) KoalaCalc 26) Little Snitch 27) MacTheRipper 28) Mail 29) MainMenu 30) MS Word 31) MS Excel 32) Overflow 33) PopChar 34) Preview 35) QuickTime 36) Safari 37) Service Scrubber 38) SuperDuper! 39) System Preferences 40) TextEdit 41) The Unarchiver 42) Toast Titanium 43) Utilities 44) VLC 45) VoodooPad Plus widgets: 1)GMail Widget 2)Delivery Status 3)Address Book 4)Weather 5)Dictionary 6)Egg Timer 7)Unit Converter 8)PEMDAS Calculator 9)Flight Tracker 10)iStat Nano 11)k-Notes 12)NotePad And that's it, folks! And here's the amazing part - I have a lot of documents, including 450MB worth of icons - so without the icons, I'd be a hair over 3GB hard drive space used! The result is a zippy computer - very fast, and very clean. I use iDefrag and MainMenu to keep it in shape. Now, granted, I use my iBook as well for video and music editing and specialized work, but for everyday ordinary use, the mac mini is just great. So what is YOUR app list, and your hard drive space used? Post the list and the number!
