These are the apps that have stood the test of time with me. Others have come and gone, but these have endured:
Utilities
- Launchbar (Quicksilver is great but Launchbar is more stable IMHO)
- Compost trash utility
- Macaroni system maintenance
- DefaultFolderX so I can tag files as I save them
- Filespot for searching file tags and metadata
- TypeIt4Me for speeding up regular text entry
- Hazel for defining folder rules
- Growl for system messages
- Interarchy for FTP (also have Transmit but Interarchy seems more reliable)
- Keyboard Maestro for macros
- Pathfinder for enhancements over Finder
- SuperDuper for image backups
- Chronosync for file and folder sync'ing
