 Feedback received from both Motorola and the UK distributor (myhome247) is that there are no plans to provide a driver for Macintosh or Linux/UNIX OS's.The latest version of the Homesight software does run on Windows Vista and is available from www.myhome247.co.uk.The XG1000 base unit is completely stand-alone (does not require a USB internet connected host) and does not require an always-on computer but is $200 vs $100.
