QX 2020 doesn't work with MAC OS BIG SUR?

Greetings yves299,

Thanks for visiting the Apple Support Communities! It seems an app isn't working with macOS Big Sur.

Check out the troubleshooting in the following article: If an app freezes or quits unexpectedly on Mac - Apple Support

Reach out to the app developer if the app continues to have problems:

Kind regards.

You should visit the Quark site and determine when they will have a Big Sur compatible version of their software ready. They have had months to make their software compatible, and apparently that was insufficient.

There have been a couple of threads on this and it boils down to the following:

QX needs an update. Apparently Q will release an update sometime in December.

What then happens is the posters all announce that they will decamp to InDesign or Affinity. Mind you, if they haven't gotten tired of Q by now, they never will IMHO. But there you go.

All other queries need to go to Q.

Decamping despite subscriptions, document interchange, and learning curve. 🧐 We have heard it all before…
