[Bug 1573160] Re: [Mac hardware] package fwupdate 0.5-2ubuntu4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Mario Limonciello]

Originally the design was supposed to install fwupdate during ubiquity so
that decisions like that could be made. That ended up not happening and
it's instead seeded to all installations.

I think a possible consolation is to in the postinst script  either test
for running on a Mac or instead test for installation to an hfs+ partition
of the bootloader and abort that step. Neither are really ideal however.
