This appeared on my screen when I started Music Collector on my Macbook Pro, MacOs Tahoe 26.4.1.
It´s from Apple (Using Intel-based apps on a Mac with Apple silicon - Apple Support)
Using Intel-based apps on a Mac with Apple silicon
Rosetta enables a Mac with Apple silicon to run Intel-based apps. Support for Rosetta will end in a future version of macOS, so check with the app’s developer for an updated version.
If you get a notification that support is ending for Intel-based apps, and that the app or a component used by the app will not work with a future release of macOS, learn how to update Intel-based apps for Apple silicon.
About Intel-based apps, Rosetta, and the transition to Apple silicon
In 2020 Apple announced the transition from Mac computers with Intel processors to Mac computers with Apple silicon. Rosetta was designed to ease this transition by automatically translating Intel-based apps for use with Apple silicon. This has given users and app developers more time to update their apps for Apple silicon.
Rosetta is currently available for any Mac with Apple silicon, and it will remain available through the forthcoming macOS 27 — the next major macOS release. Starting with computers using macOS 28, Rosetta functionality will be available only for certain older, unmaintained games that rely on Intel-based frameworks. Find out which macOS you’re using.
For optimal performance and future compatibility, you should update your Intel-based apps, plug-ins, extensions, and other add-ons for Apple silicon.
What will happen to Music Collector when Apple updates to MacOs 27 this fall? Will I still be able to use the program in the Future?
