Very Lightweight and handy DM for Mac(and Windows) with perfect browser integration and easy video downloading features.
Really worths a check.
Ranked in these QuestionsQuestion Ranking
Pro Lightweight and fast
Downloads are quite fast due to the concurrent download technology and the fact that the program is compiled in C##.
Pro Like IDM on Windows
Pro Great workaround for Google Chrome's annoying download interrupting "security" feature
Neat Download Manger for Mac is a great way to stop Google Chrome from interrupting file downloads with it's annoying "safety" feature that requires user intervention to keep a download or delete it. Somehow the browser extension enables Neat Download Manager to bypass Chrome's native download function.
Pro Can change the default Download directory
And no, it won't create a default folder structure based on categories.
