Hurry up, some new stuff!
Apple has just released the new version of macOS, Catalina (10.15). Great, I absolutely need to download this jewel right now!
No, no, no, no!
Absolutely not! In a production environment, you must be careful with new releases!
In addition, this new version of Apple’s OS breaks the compatibility of 32-bit applications, which means that many applications will no longer work after this system update!
In particular, not all our dear graphic applications are compatible yet. Apple changes the specifications of its software until the last moment, so software vendors must wait until the official version is released before doing their intensive testing and releasing a compatible update of their software.
To date, we strongly advise against updating.
To check the extent of the damage to your working environment, we recommend using Go64 from St Clair Software, a freeware that will list all applications involved (remember to choose “All Executables” to test plugins as well, not just applications”).

So be very careful!
This is the perfect time to remind you this computer adage:
If it ain’t broken, don’t fix it!
[Update]
I just received an email from Enfocus about this – I share it with you here:
Soon, Apple will release macOS Catalina.
The current Enfocus products will not officially support macOS Catalina when it is being released. We strongly advise customers not to upgrade their mac to macOS Catalina until we release officially supported updates to our products.
PitStop 2019 update 1, Connect 2019 and Switch Fall 2019 will officially support macOS Catalina, and will be available shortly after the macOS Catalina release. The reason for this delay is that we want to test with the officially released version of macOS before we can guarantee compatibility.
Kind regards
The Enfocus Team
