Sports Interactive has patched Football Manager 2005 to version 5.0.2 on PC and Mac, and we've taken the trouble to mirror them on Eurofiles. Here be PC, here be Mac. And, for the record, it was trouble. Oh the faffing.
Anyway, SI's plan with FM 2005 is to release fewer patches but fix more things at once, as you can see from this vast list of changes on the SI forum, and the developer is also keen to find out how fans of the game feel about this approach. So comment.
It's about 15MB in size on the PC and a bit larger on the Mac, and SI says that save games will generally be fine between versions; any exceptions are outlined in the abovementioned thread. And with that: patch.
