Re: Sweet Home 3D 5.7
With the free version under Mac OS X, , click on the application icon of Sweet Home 3D while maintaining the ctrl key pressed to display its contextual menu, choose Show Package Contents item, open the Contents folder, edit the Info.plist file by dragging its icon on TextEdit application and update the maximum memory in the text <string>-Xmx1024m</string>, writing for example <string>-Xmx2g</string> for 2 GB instead of 1024 MB. Finally, save the file and relaunch Sweet Home 3D.
