Maybe there is something wrong with the hardware or the system installation.

It works fine on all Macs that are part of the official isabelle-dev
test infrastructure. See also Admin/PLATFORMS (Isabelle/c360f3b603f8):

  x86_64-darwin     Mac OS X 10.10 Yosemite (macbroy31 MacBookPro6,2)
                    Mac OS X 10.11 El Capitan (macbroy2 MacPro4,1)
                    macOS 10.12 Sierra (macbroy30 MacBookPro6,2)
                    macOS 10.13 High Sierra (!?)
                    macOS 10.14 Mojave (!?)

This also shows that 10.13 and 10.14 are presently not covered: there
has been a general decline in Mac support in recent years. Isabelle on
macOS presently hinges on a somewhat pathetic Mac Mini that I have at home.

It would be great to recover some old vigor concerning isabelle-dev
platform coverage: via regular OS installations with regular SSH access.
Maybe even with nightly build_history measurements via isabelle_cronjob
(not Jenkins).
