Many Tricks (http://manytricks.com/) has updated Leech — a Mac OS X download manager that lets users queue, pause and resume downloads, download from password-protected servers and store their passwords in their system-wide, secure keychain — to version 2.0.4. The upgrade installs a new version of the in-app purchasing module.
To use you open Leech, drag your URLs and start downloading. You can: limit the number of concurrent downloads; mark URLs for download without actually starting the download ; and shut down your Mac when all downloads are done. Leech supports drag and drop and the Mac OS X Keychain.
It’s Universal Binary so runs natively on both PowerPC and Intel Macs. Leech requires Mac OS X 10.5 (“Leopard”) and costsUS$15.
