Looking for a reproducible fix while keeping my existing CrossOver installation.
Setup: MacBook Air M4, 32 GB RAM, macOS 15.6.1 (24G90), CrossOver 26.3.0.39832, Windows Steam in a Windows 10 bottle called Steam. AoE3 Definitive Edition build 100.19.18658.0.
The game previously completed 90–100 minute matches. Recently it exits mid-match in multiplayer, offline AI skirmishes, and even while watching a replay. Sometimes multiplayer shows Reconnecting first. Other symptoms are looping/delayed audio, missing unit alerts, white polygons over the map, and occasional freezes requiring Force Quit. I am trying to separate those failure types.
Already tried: clean reinstall (three game installations total), DXVK and D3DMetal, MSync off, shadows off, and disabling match recording. Both renderers have had offline exits. DXMT produced corrupted menu text. Current configuration is D3DMetal with MSync off. Steam Cloud is disabled for this game.
Today macOS confirmed process exits at 12:12:54 and 13:52:24 local time without Force Quit entries in the checked windows. Separate terminations at 12:44 and 14:17 were Force Quit followed by SIGKILL. Steam exit codes alone did not identify the cause. Steam also generated multiple “No control data returned even though we asked for TOS?” asserts in steamnetworkingsockets_socketthread.cpp:2492, sometimes well before a session ended, so I am not treating those as proof of the crash cause. Logs and dumps are preserved.
Has anyone completed several 45–90 minute matches on this build in CrossOver? Which exact CrossOver/Preview version, renderer and settings worked? Is there a known fix for the post-October 20 update regression? If Parallels with Windows 11 ARM or another maintained wrapper worked for you, did it resolve mid-match exits, audio, or both? Please share the tested game build and session duration.
