ArkMS shares photos, videos and music from a Mac to Xbox, PlayStation, iPad and Android devices over the home network. The page lists support for 4K and 8K video, multi-streaming and wireless DLNA and UPnP speakers. A fully functional trial can be downloaded, and a lifetime licence covers two Macs.
Check that your TV or speaker supports DLNA before you buy the licence. Each voucher code for Arkuda Digital is checked before it goes live.
