Installer window doesn’t show up on macOS Big Sur

This post was originally published on this site



One of my colleagues reported the following:


“On macOS Big Sur, the installer window is completely transparent. Only the shadow around the window can be seen.

As a result no progress is visible.


The installation happens without any issue but the actual window is completely transparent.


I tried to grab a screenshot but not even that is possible.

The shadow around the window doesn’t register at all.”


The exact same installer works fine in Catalina and older versions of macOS, and we’ve never experienced this kind of display issue.


This begs the question: when will InstallBuilder add support for Big Sur?
