Engineered for macOS Power Users & Developers
Native performance meets deep system control. Take back command over your workspace topologies.
Two-Tier Topology & Window Memory Restoration
Reconnecting monitors or waking from sleep compresses your windows onto the primary display. MacDeck detects display counts and resolutions to restore windows to their designated screens and Spaces.
- Chrome Multi-Profile Isolation: Distinguishes between separate Google Chrome profiles (Personal, Work, Sandbox).
- Fullscreen Space In-Place Retention: Retains fullscreen Spaces via SkyLight private frameworks without animation stutter.
- Hardware-Aware Display Aliasing: Adapts reliably even when monitor hardware UUIDs shift.
- Zero-Background Footprint: Automatically terminates after restoration to free 100% of memory.

Frequently Asked Questions
Details regarding security, permissions, and architecture
Why does macOS show "Apple cannot check it for malicious software"?
MacDeck is completely free and open-source software, distributed independently without paying Apple's $99/year commercial developer program. This is standard Gatekeeper behavior for independent binaries.
Simply open Terminal and execute this command to clear the quarantine flag:
xattr -cr /Applications/MacDeck.appWhy is Accessibility permission required?
Under macOS sandbox policies, manipulating and repositioning windows of other applications requires the native Accessibility API. MacDeck never records keystrokes or screen captures. Configurations are saved locally as plain JSON in ~/.config/macdeck/.
Does it support Intel-based Macs?
Yes. While the system dossier highlights Apple Silicon architecture, the window restorer, environment doctor, and package hub fully support Intel Macs running macOS 13+.
Does MacDeck drain battery in the background?
Not at all. You can even check 'Auto-quit after restoration'. It launches, completes calculations in milliseconds, and exits cleanly.
