IDA Pro is awesomesauce, Wireshark for binaries. So much better than Turbo Debugger and ICEs in the olden days.

Just FYI it's no surprise that the IDA Pro wine torrent for OSX (magnet ...116a37) floating around out there has malware in it. Best to get it directly from a friend at a large shop. If you're a pentester or researcher, buy it obviously.
