From 666820c918f4dbbb99ff6456ec25ff59aeea1eea Mon Sep 17 00:00:00 2001 From: JetSquirrel Date: Wed, 30 Sep 2026 13:34:24 +0800 Subject: [PATCH] Compress the dmg with LZMA UDZO (zlib) packed the current build into 32 MB; ULMO (LZMA) packs the same app into 19 MB. Every macOS DuckLocal supports mounts it, and the installed app is unchanged.
