Apple have released a new OS update yesterday called El Capitan.
As with most OS updates, things change, and this is no exception. Thankfully, when it comes to Delphi and C++ Builder running on El Capitan, its pretty straight forward, the only thing required is to update the PAServer. The update is available from Code Central http://cc.embarcadero.com/item/30398.
