When I delete videos from the emulator, the disk weight doesn't go down and it's consuming space on my Mac, how can I clean up space?

In Genymotion Desktop, the disk usage can also come from Caches and the Media folder, not only from the videos inside the virtual device. Open Settings > Storage and use CLEAR for caches, then OPEN for the Media folder to remove leftover files. Genymotion Desktop Global Settings

If you want to recover more space, also check Virtual devices in the same Storage tab because inactive devices and system images still use disk space. The launcher footer shows the total space used by Genymotion and all components. Genymotion Desktop Global Settings
