Since Microsoft does not make a native version of SQL Server Management Studio for the Mac I have been forced to run it under Parallels which works but sometimes can be a bit cumbersome. RazorSQL came up in my search as a great way to duplicate the functionality of SQL Enterprise Manager from a native mac application. I really like Querious but it does not connect to MS SQL Server. I’ve used to extensively the past few days on a project and it seems to be friendly to both hard core programmers and know enough to be dangerous folks like myself. I have found the simple double click to edit a field option very useful and then it writes the T-SQL for you to update the table. Anywho… it is good enough for me and priced fairly.
