Currently, Genymotion Desktop requires Rosetta to work on Apple Mac M series, due to dependencies to Intel-based libraries for the graphical interface.
However, you are receiving this alert because Apple plans to remove Rosetta support in macOS 28, which should be released by fall 2027.
We are aware of the situation, and we are working hard to remove all the old dependencies to make Genymotion Desktop 100% arm64 in future releases.
For the moment, and until fall 2027, you can safely ignore the alert and keep using Genymotion Desktop on macOS.
