InfoClick is a great tool for searching and finding email in Apple Mail. However, to get the most out of InfoClick you need to have it analyze and index your email constantly. Also, I’m impatient and I want things when I want them. The best way to do that is to have InfoClick launch at startup so that it can index new emails in the background.
To do this, go to your InfoClick preferences and check “Open InfoClick automatically when you log in.”
Once you do that InfoClick will launch at startup and will be ready to go when you need it.
