I  know….i know that Speed Download is the best available download manager for Mac…but it’s not free.

Progressive Downloader is a  good free alternative as download manager for your Mac. It supports multi-thread downloading and mirror search which means that it allows user to download files faster as every thread can use its own server.

Another nice feature is the Filehosting services plug-in. There’s no need to wait for the download button to appear anymore. Just add your links to Progressive Downloader and it will automatically do the rest. Just to name a few of the supported hosts: RAPIDSHARE, SENDFILE, MEGAUPLOAD, FILESONIC, FILEFACTORY, and more.

I really recommend this download manager and you can download directly from HERE
