MemoryGuard 1.3.1

MemoryGuard 1.3.1 makes the answer visible: every recognized group is now classified as heavy or below the selected profile threshold.

Improved

• Heavy/recognized counts in Overview and the menu bar
• Per-group active, paused and weight classification
• History clearing now leaves the history empty
• Accurate loading state before the first memory sample
• Faster, accessible and hardened product page

Validation

• 20 tests passed
• Thread Sanitizer and Address Sanitizer passed
• Apple-silicon app archive verified after extraction
• SHA-256 checksum included as a release asset

The app remains free, local-first, ad-hoc signed and not Apple-notarized.

MemoryGuard 1.3.0

Free public release

MemoryGuard is a native, local-first macOS utility for developers running multiple heavy builds.

What it does

• Watches available RAM, kernel pressure and swap together.
• Recognizes Next.js, Swift, TypeScript, Vitest and Playwright build groups.
• Temporarily pauses only the newest eligible group when at least two heavy builds exist.
• Resumes automatically after two healthy samples.

Safety contract

• No deleted files or caches.
• No terminated apps, tabs, terminals or processes.
• No telemetry or cloud account.
• The only heavy build is never paused.
