I am starting a project in Joomla. Web server is Apache on Mac.
The database I would like to run on is a remote Microsoft SQL server. I am only given the option of installing with mysql when I hit the install page.
Microsoft provides PHP drivers, but they are Windows only.

Are there any other options?
It won’t work, MS SQL is not supported by Joomla at this time. The problem you will run in to is that they have very different implementations of SQL syntax. Basically, the queries used for MySQL don’t necessarily work in MSSQL. You would need to rewrite all of the queries in the Joomla framework to use MSSQL syntax, which would be a tremendous undertaking and would make it near impossible to add extensions or Joomla updates.
