Hi. Downloaded to the Mac's Hard Disk. Unzipped there. Launcher works.

Hi Frode. Forget my last two messages (I leave them there because maybe there is something useful, but I think the problem was the loading of the database didn't occur because a problem with the pen drive).

I think I've got the solution for the first of my today's posts: Changing the pen drive. I think that for whatever reason the pen drive that I was using had something wrong, was corrupted or whatever...

So, in summary, 2.5.5dev3 works correctly on portable devices in OS X 10.9.3 and in a MacBook Air with an Intel Core 2 Duo (tested also in a newer Retina MBP Core i5 and also OK). 2.5.4 didn't launch in the MacBook Air, so the change you've made in this release definitely has worked. I think we now have all the problems with the OS X version solved:
- Core 2 Duo and up support
- Retina Display support
- Portable version in pendrives correctly working.

Thank you very much.
