macOS Tahoe (26.x) — MT5 main window auto-closes after visual Strategy Tester completes

[Reihan Hafidz]

Environment:

- MetaTrader 5 for macOS (native MetaQuotes Wine wrapper)

- Wrapper build 5.0.5834, terminal build 5833

- Wine 11.1, winemac driver

- macOS 26.5.2 (build 25F84), Apple Silicon (arm64)

Bug:

After a Strategy Tester backtest in Visual mode finishes, the MAIN terminal

window is destroyed/closed automatically, while the visual tester chart window

stays open. The process keeps running, but the main window cannot be restored

via Dock click, Cmd+`, the Window menu, or Mission Control — only quitting and

relaunching the app brings it back.

This did NOT happen before updating to macOS 26.5.2. It reproduces every time.

Request: please fix winemac window-lifecycle handling for macOS Tahoe.

Please launch the Mt5 from the system terminal and after the crash send the crash log to [e-mail].

/Applications/MetaTrader\ 5.app/Contents/MacOS/MetaTrader\ 5 > ~/mt5.log 2>&1

or

/Applications/MetaTrader\ 5.app/Contents/MacOS/MetaTrader\ 5 2>&1 | tee -a ~/mt5.log

or

stdbuf -oL -eL /Applications/MetaTrader\ 5.app/Contents/MacOS/MetaTrader\ 5 2>&1 | tee ~/mt5.log

Also check if the moment of fall coincides with the sound signal.
