Past for iChat 4+

Past for iChat is a little application to open and view old chat log files created by Apple's iChat application (.ichat and .chat files) on macOS Big Sur, Monterey and later. iChat was the predecessor of the new and improved Messages app.

Starting with macOS Big Sur the refreshed Messages application doesn't support opening old iChat chat log files anymore. Past for iChat keeps your history alive by allowing you to open those.

The application also features a simple Markdown export of the chat logs and a Quick Look plugin for previewing chat logs in Finder, Spotlight or other applications.

Note: This application is only useful for people with older iChat chat log files (usually older than 5 years). I.e. this app does neither open files created by Big Sur/Monterey itself, not iPhone chat logs.
