As mentioned Quicksilver and Audio Hijack Pro are great programmes.www.pure-mac.com
is also a good site with recommendations. www.versiontracker.com/macosx/
is good, too.
Other Mac-specific apps I'm using on a constant basis:
- Appzapper (for uninstalling programmes)
- SuperDuper (for doing backups - the shareware lets you do backups but with the full version for $30 you can do smart backups which only takes 3 minutes if you already have a previous backup)
- Parallels Desktop (for the few programmes that aren't available on Mac)
- Adiumx (msn, yahoo, aim, etc.)
- Toast (the Nero for Mac)
- Perian (codec package for Quicktime; otherwise VLC has various codecs already integrated)
- Onyx (cleans and optimizes your system, to be used from time to time)
More specific use apps
- X-Chat Aqua (best IRC client)
- Fetch (great FTP client)
- Max (codec converter but it's not as good as dbpoweramp)
- Shapeshifter (for changing themes)
- Iridium (my favourite theme and the one I'm using, which is simply Mac's Aqua with platinum colour instead of brushed metal, very easy on the eyes)
Then of course the Windows programmes that are on Mac such as Office, Adobe CS, Skype, etc.
Another thing is that it takes a bit of time to get used to Apple's Mail, address book and iCal, but I find it to be a coherent and more easy-to-use package that I prefer it over Microsoft Entourage (Outlook on Mac). Mail also lets you access exchange servers.
Macs aren't perfect either but the times where I just want to punch the computer screen has been reduced to a mininum since I got a Mac. And you can always use Parallels Desktop for the few Windows programmes that aren't so good or not available on Mac, or Boot Camp if you're into games.
Which plug-ins are you using in Audio Hijack Pro?
