Fetch Softworks has announced the availability of Fetch 4.0.1 — an update to the company’s popular FTP application. Version 4.0.1 fixes an incompatibility between Fetch 4.0 and Mac OS 10.1. Fetch 4.0.1 is a free upgrade from 3.0.3 or 4.0; the serial numbers for those releases will also work in 4.0.1.
