As was suggested earlier in the list, the best download manager for the Mac is ... none.
Sorry...I don't get that statement.
A download manager will re-start a partially downloaded file.
A download manager will parallel download to speed up downloads eg...I am at present downloading through my mac at 500KB/sec from a site
Using Internet Download Manager (windows) the same file will download at 2.4MB/sec and be able to be resumed at will.
How on earth is no download manager better ?
I am at present trying folx which seems to meet most of my criteria....will probably purchase the pro version to allow parallel downloads
