Path of Building (PoE2) — Native macOS Port

An offline build planner for Path of Exile 2, running natively on Apple Silicon macOS.

Side project notice: This is a personal side project. It may contain bugs and is not officially supported. I use this app actively and will keep it updated as best I can. Feedback, bug reports, and contributions are very welcome — thank you!

This is a native macOS (Apple Silicon) port of Path of Building Community for Path of Exile 2.

It keeps the original Lua application and the entire calculation engine unchanged — every offence/defence calculation, the passive tree, items, skills and import/export logic are identical to the upstream project. Only the Windows-only SimpleGraphic runtime has been replaced with a native macOS host (SDL3 + LuaJIT + a bitmap font/DDS renderer), so it runs as a real .app instead of through Wine/CrossOver or the Windows .exe.

⬇️ Download

Download the latest release — grab PathOfBuilding-PoE2-macos-arm64.zip from the assets, unzip, and move Path of Building (PoE2).app to your Applications folder. See Install below for the first-launch (Gatekeeper) step.

Requirements

• Apple Silicon Mac (arm64)
• macOS 13 (Ventura) or newer

Install

Download the latest PathOfBuilding-PoE2-macos-arm64.zip from the Releases page, unzip it, and move Path of Building (PoE2).app to your Applications folder. On first launch, macOS Gatekeeper may require you to right‑click the app and choose Open (it is not notarized).

Your builds and settings are stored under: ~/Library/Application Support/Path of Building (PoE2)/

Is it safe? (account sign-in & privacy)

Yes — and you don't have to take that on faith. This app talks only to Grinding Gear Games' official servers, has no telemetry, and never sends your account, tokens, or builds to anyone. Sign-in is optional and uses the standard OAuth + PKCE flow: you log in on pathofexile.com in your browser, and the app never sees your password. See SECURITY.md for the full breakdown (including how to verify or build the app yourself).

Features

• Comprehensive offence + defence calculations:
  • Calculate your skill DPS, damage over time, life/mana/ES totals and much more!
  • Can factor in auras, buffs, charges, curses, monster resistances and more, to estimate your effective DPS
  • Also calculates life/mana reservations
  • Shows a summary of character stats in the side bar, as well as a detailed calculations breakdown tab
  • Supports all skills and support gems, and most passives and item modifiers
  • Full support for minions, party play and support builds
• Passive skill tree planner:
  • Support for jewels including most radius/conversion and timeless jewels
  • Alternate path tracing (mouse over a sequence of nodes while holding shift, then click to allocate them all)
  • Fully integrated with the offence/defence calculations
  • Can import PathOfExile.com and PoEPlanner.com passive tree links
• Skill planner: add any number of main or supporting skills; toggle auras/curses/buffs on and off
• Item planner: paste items straight from the game, search trade, craft items, and browse a unique/rare database
• Import your characters directly from your Path of Exile account (OAuth sign-in)
• Share builds with other Path of Building users via build codes

Building from source

See docs/macos.md for full build/package instructions. In short:

brew install cmake ninja sdl3 luajit curl zlib zstd
tools/macos/build_app.sh      # builds build/macos-arm64/PathOfBuilding-PoE2.app
tools/macos/package_app.sh    # produces dist/macos-arm64/PathOfBuilding-PoE2-macos-arm64.zip

What's different from upstream

The calculation engine, data, passive tree, skills, items and UI logic are unchanged. The changes below are what make it run natively on macOS:

• Native macOS host (macos/) replaces the Windows-only SimpleGraphic runtime: a Cocoa + SDL3 window with layer-correct draw ordering, a bitmap font renderer, DDS/TGA texture decoders, libcurl-backed HTTPS downloads, a loopback OAuth sign-in server, and background sub-scripts. The app loads its bundled Lua from inside the .app (Contents/Resources), falling back to the source tree when run from a checkout.
• macOS-native conventions: keyboard shortcuts use Cmd (e.g. Cmd+1–7 to switch tabs, Cmd+S to save, Cmd+` for the console), and user data is stored under ~/Library/Application Support/Path of Building (PoE2)/ instead of the Windows path.
• Windows runtime removed: the .exe/.dll binaries are not shipped. Only the shared Lua sources, fonts (runtime/SimpleGraphic/Fonts) and Lua libraries (runtime/lua) are retained.
• Updates: there is no in-app auto-updater on macOS. The Check for Update button instead opens the Releases page so you can download the newest build, and each release ships a SHA-256 checksum to verify the download (see SECURITY.md). The About dialog links to this repository.
• Versioning: releases keep the upstream engine version and add a macOS build counter (e.g. tag v0.16.0-macos.1), shown in-app as Version: 0.16.0 above macOS Port (build 1). See RELEASE.md for the scheme.
