During installation PATH environment variable should be updated. For example to make permanent changes for PATH variable /etc/paths file should be modified and that requires administrative privileges.

For Alpha release we could be running installer with sudo

sudo open DevSuite.app

Another option to investigate is using AppleScript and run the same shell script above with elevated privileges like this

do shell script «open DevSuite.app» with administrator privileges

that would trigger standard UI Dialog requesting user login/password with administrative privileges. This should be included int DevSuite.app package configuration after it is assembled by electron packages.
