Developing and testing web apps that target Microsoft SQL Server are a breeze on Windows because you can leverage SQL Server Express LocalDB. This is not the case when developing on a Mac as LocalDB or SQL Server full are not available natively. The options are then to either target a remote database, either on-prem or cloud, which quickly becomes expensive and pushes out the inner loop development time. Another option could be to use SQLite when in development, as this is supported on a Mac, but then you risk having unforeseen problems when deploying to production as the two databases are not equivalent.
