Just updated: Mac OSX
and Version 6.2.31.6349 (Sep 24 2026)
Dorico 6 AudioEngine Version 6.1.1.25
Looks like a font problem. What is your default music font set to, would restarting the computer or checking the Mac font utilities help?
As far as I know Steinberg doesn’t make OSX so if the only change was an OS update you might want to ask Apple?
I don’t think this is as helpful as one might think. Dorico 6.2.3 was not fully compatible with macOS 27 (Golden Gate). Thus the latest Dorico update.
Perhaps it would be more helpful to respond as @Derrek did with ideas for checking various things like the font. And, this forum is as much for assistance with issues after OS updates/upgrades as it is anything else as far as I can tell.
Hi @Fred_van_de_Biezen ,
as already @Derrek proposed, please restart your computer and see how it looks like after the reboot. I expect it to be fine again.
I did restart yesterday several times without results. This morning I restarted again and first tested Dorico and what happend… the fonts correct and every part of Dorico is working fine again.
kasky1 your right! Sorry about that, I just have seen one too many “it worked yesterday but now that I upgraded my OS it doesn’t, fix it!” posts over the years and it gives me a itchy trigger finger 
I’m glad everything worked out in the end!
