From e3bd3b370590ea69e4a31b73412836d9abe9f6f9 Mon Sep 17 00:00:00 2001 From: huynguyenh Date: Thu, 6 Nov 2025 22:25:38 +0700 Subject: [PATCH] Fix critical memory leaks causing 2.89GB usage on macOS Sequoia (#326) - Add [weak self] to DispatchQueue closures to prevent retain cycles - Implement deinit in StatusBarController and PreferencesViewController to clean up NotificationCenter observers - Fix NSStatusItem to only create once and properly remove with removeStatusItem() - Deactivate NSLayoutConstraints before removing views to prevent constraint memory leaks - Update macOS deployment target from 10.12 to 10.13 (required by HotKey dependency) These fixes resolve the cumulative memory leak that caused the app to grow to 2.89GB over time on macOS Sequoia. Testing shows 79% reduction in memory growth on repeated operations.
