Answer 1

Hello,

MAUI search bar is rendered by UISearchBar on iOS/Maccatalyst platforms. This glass is an icon, and it cannot be clicked by default. Please see Apple's description: UISearchBarIconSearch | Apple Developer Documentation and the searchbar section in iOS Human Interface Guidelines

If you want to trigger the command to search, you can press the return/enter key on your Mac's Keyboard.

Best Regards,

Wenyan Zhang
