You may be familiar with the excellent IRC client for Mac OS X known as Textual. Unfortunately, it’s only available in the app store, and the app store version is sandboxed – so your logs are in a black hole somewhere and it’s a pain to install custom styles.
Luckily, Textual is BSD-licensed, so there’s nothing stopping someone from creating and distributing their own builds. So without further ado, I present a non-sandboxed build of Textual that doesn’t suck.
Also, buy this from the app store to support the author.
