The only negative side of Total Commander is I'm extremly used to it - been using it since mid 90s. When I compare alternatives on Mac I'm searching for exact keyboard commands, navigation patterns, etc. I'm using Crax Commander, but it's not the same.

TC is probably one of the reasons I don't care that much about problems in newer versions of Windows, I don't use Explorer, I don't use windows search, text is viewed with Lister and not Notepad...
