Is ARM support available only for Genymotion SaaS?

High Confidence (78%)
so arm is allowed only for SAAS ?

No. ARM is supported in Genymotion Desktop on Mac M, and in Genymotion SaaS for arm64 images. Genymotion Desktop on PC and old Mac Intel uses x86/x86_64, while SaaS is moving to arm64-only for Android virtual devices.

Are you trying to run an ARM-only app on Desktop or in SaaS?
