SpellList 1.0 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available.
Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. The program lies within Productivity Tools, more precisely Office Tools. The actual developer of this free software for Mac is Mark Noble.
From the developer:
SpellList is a utility application which lists spells from the Pathfinder RPG with a semi-natural language filter. The bottom text field is where you enter the filter queries to filter down the spells listed. When the query is typed in, the text will be one of three colors: red is for syntax errors or invalid attributes, verbs or fields, blue stands for bracer mismatch, and black is for valid.
You may want to check out more software for Mac, such as PitStop Extreme or FileOpenInstaller, which might be similar to SpellList.
