Best would be to raise this with our Support team, as this most probably can be addressed through changing the client (project/files storage location) or server-side (permissions, like missing Edit Project) configuration.
In technical details, we don't have any native macOS version of Trados Studio available, and it always needs to be run in a form of virtualization (e.g. through Parallels). This type of virtualization still runs Trados Studio in a (virtual) Windows environment inside the macOS. In such a virtual Windows setup, Trados Studio in this context should behave the same as run in native Windows. Our Support team will be able to assist you with identifying the cause for the automatic disabling of providers.
