Looking for a recommendation for a tech lab file recovery software we can reuse as the need arises. Would prefer something that will work on mac / windows - or at least includes the licenses for both OSs.

Restore with original filename a bonus as well.

We have a HDD in the shop here that has failed (OSX) and using some of the trial ones, we can see some files, we would just like to make the investment worth while for us and not to have to pay out for each possible need, instead, an unlimited license
