do you have any other frontends available on linux?

it could be the main database, or the database as used by one of the
frontend plugin...

in anycase, you need to run a mythfrontend as recent as the mac one,
that will perform the upgrade before you can start the mac one.

that, or install mysql on your mac and make sure it's in the path, so
mythfrontend can perform the database backup

normally, no

doesn't mean it's the last one

because it's always done that way

prior upgrading the database, it attempts to make a backup. If the
backup fails then the upgrade won't occur.

the mac can perform the upgrade, but not the backup unless you
manually installed mysql and made it available in the PATH

because you are running a version identical to the one in your
backend. so it doesn't attempt to perform an upgrade.

the mac one is more recent and needs an updated version.

what's so hard to understand?

none of the data you have provided so far contradict what I posted
earlier, quite the opposite, it made it even more obvious about what
the problem is.

now, either you do what I tell you to, or you can try your own way....
it's up to you
