I just hooked up my brand new iMac 2.0 duo core and am wondering if there are any must have updates, widgits, performance downloads that I should install? I heard there's one for making the processors run cooler?
Software update is always a good thing with a new machine. After that, name your machine, load up iTunes, iPhoto, customize the dock, and go searching Apple.com for widgets.
Also, check out the forums to see what software people recommend.
I'd suggest in no particular order: BBEdit, Awaken, Album Cover Finder, iConquer, RDC, Mac the Ripper, Fetch, Airfoil (if you have an Airport Express), CoverBuddy, MacJournal, Firefox (for dodgy websites), Flip4Mac, and Graphic Converter.
I'd suggest iStat and the Minesweeper widget (to calm Windows users ).
Also, enabling the Debug Menu in Safari is pretty handy because it let's you change the user string in Safari and pretend to be a Windows computer, or immediately change the browser to Firefox in case a website doesn't render properly.
