Remote Desktop Manager for Mac Free Edition is indeed free, but requires registration after 30 days to be able to use the application. To enable you to fully test the Free Edition prior to providing your email address, we have granted a 30-day grace period during which no registration is necessary.
Upon every application launch, the Register the application window is displayed. It provides the number of remaining days in the grace period, and the source choices for the registration data.
Every holder of a Devolutions Cloud account (also free of charge), is assigned a license serial for all our complementary products.
By selecting Use registration from Devolutions Cloud, a credentials prompt is displayed upon clicking OK. The license serial will be retrieved automatically from the provided account.
