Swiss Railway Clock 1.1

Bug Fix

Fix macOS Sonoma legacyScreenSaver high CPU/RAM issue

On macOS Sonoma (14.x) and later, third-party screensavers have a system bug where the legacyScreenSaver process doesn't exit properly when dismissed, causing high CPU and RAM usage.

Solution

Implemented in-frame orphan detection that checks every ~1 second:

• Window no longer exists
• View detached from superview
• Window no longer visible

When detected, the process exits cleanly to prevent resource waste.
