What is new in PureMac 3.1.0

## PureMac 3.1.0

Universal binary (Intel + Apple Silicon). Signed with Developer ID + notarized + stapled by Apple.

### What changed

- Simplified Chinese completed and runtime strings routed through the catalog (#180), German (#167) and Italian (#174) added; every interface string is now localizable.
- A Settings page in the sidebar with appearance, language and Full Disk Access in one place; the standard Settings window shows the same page (#169).
- Check for app releases from Settings, user-initiated only; the unused Sparkle framework no longer ships (#170).
- Startup and background items collapse, and Performance shows app CPU and memory usage on demand (#172, #173).
- XcodeBuildMCP and MobileBuildMCP DerivedData in Xcode Junk, opt-in and Trash-only (#162).
- The Protection check recognizes the firewall's block-all mode (#183), and the Homebrew cask no longer warns about postflight (#182).
