UPGRADE to MacOS High Sierra? Our plan…

Hi all,

as every year, please allow me to remind you of having a backup – or better: a clone – of your current production machine, if you plan to upgrade to the newest version of MacOS once Apple releases it on Sep 25, 2017.

As there is no built-in way to revert to an older MacOS, please create a clone before upgrading: ... if-needed/

Though we do not know of any serious issues of QuarkXPress 2015. 2016 or 2017 with the Golden Master of High Sierra, Apple might still implement substantial changes before release.

As every year we will need to first test the release version of Apple's newest version of MacOS, so High Sierra aka 10.13, before being able to certify it. Apple communicated Sep 25 as the release date. In the past our certification took between 5 to 21 days, after the final release of a new version of MacOS (same is true for Windows) was available.

We will most likely release an Update for QuarkXPress 2016 and QuarkXPress 2017, which add High Sierra support, on Oct 6, 2017.


P.S.: Always have a recent backup!
