Hello Ken Thank you for that - that link has worked! Not quite the desired answer for Mac users though! However, as a current alternative; how does Windows 7 perform with PTE - Is it worth 'Boot Camping' (that is installing 'Windows 7' on a separate part of a Mac Hard Drive)? And, as for a point of clarification and with my, albeit limited, understanding, a Mac version just could not be 'Part of PTE' - they are simply designed and written for different operating systems! (.exe files are 'Windows 'executable' (i.e. 'playable') files, and by definition MAC files are not .exe files?) It is just that a 'Mac' Version for File information and management would be good! But can we take as a positive that it WILL WORK (IF and )when it finally arrives? (But will 'Microsoft' actually allow this development?) Regards Geoffrey
