The PLATFORMS file documents the current situation for Isabelle support of certain Mac OS X versions, see http://isabelle.in.tum.de/repos/isabelle/file/4f0acbd97491/Admin/PLATFORMS#l25 In the past we've had particularly enthusiastic Mac system administration at TUM, but I don't see that at the moment. So I am reluctant to change a running system, especially macbroy2, which is very important for the Isabelle administration and release process. After the release, we can probably discontinue Mountain Lion, and update macbroy30 to El Capitan or Sierra. Both macbroy30 and macbroy31 are MacBookPro6,2 from Mid 2010, so it looks like Sierra still works, but that might be also the latest possible version. Note that in the long run, it is more important to have reference system installations for older Mac OS versions that for newer ones: the newer ones are more likely to be installed by current users, although that is not really a systematic test. Generally, the reference systems according to Isabelle/Admin/PLATFORMS are required for three main purposes: * Compilation of Isabelle components (via ssh) -- on the *oldest* supported version. * Routine batch-builds of Isabelle + add-on tools -- on *all* supported versions. This is usually done by the administrative cronjob. * Occasional interactive tests (via Screen Sharing), to figure out GUI portability problems, to test the Isabelle.app integration etc. We have come quite far in the Isabelle platform support, not just on Mac OS X (or mac OS). It would be sad to loose that for no particular reasons.
