This is just a note about upgrading FNC Core.
I've done this many times, and have had no problem.
Today, I ran the update and got a build error.
After one thing and another, it turned out that it was because I had never built a OSX64 app, although I had selected the platform in the Delphi install (forever optimistic).
So after creating and building a quick app (a single button), running the TMS Core update ran fine.
For those interested, the clue was in the 33,000 lines of install log. There were missing folders containing 'OSX64', 'release' etc.
