Changelog for Hotfix (added 03 April 2019):

MacOS
* Default "fullresolution" value has been changed to "desktop".
* Settings submenu has been expanded and now allows users to set their own values for fullscreen and windowed resolutions when needed.

NOTE: Windows version have that critical "bug" (fullresolution) too. I dont know where GOG find this broken launcher build.

Current offline installers - MAC v2
warcraft__orcs_and_humans_enUS_1_2__hotfix__28499.pkg (about 488,9 mb)
WIN - v1:
setup_warcraft_orcs__humans_1.2_(28330).exe (493,3 mb)
(yeah, two "_ _" symbols)

P.S. WAR1.bin and .cue have 7 audio tracks, but seems that miss MAC version, only where that .cda music originally work.
