If you are using SAM on a Mac with Mojave in Dark mode, some user interface elements will not be visible. This is due to an issue with the user interface platform that SAM is based on:
trac.wxwidgets.org/ticket/18146
To work around this issue, please change to Light mode as shown in this Apple support article:

Best regards,
