I found that I was missing several files that, if not present, will cause the app to crash when QWebEngine is used:
qtwebengine_resources.pak
qtwebengine_resources_100p
qtwebengine_resources_200p.pak.pak
QtWebEngineProcess.exe
icudtl.dat
If I use the windeployqt.exe tool, it properly places these files with my exe.
Hi and welcome to devnet,
AFAIK from the Chromium project, builds for 32bit Macs have ended by the end of 2014.
Snow Leopard was the last version supporting 32 Bit processors.
