Testing
Every review is based on a real installation on at least two Macs, real use for two weeks, timed benchmarks where relevant, and a reading of the published documentation, source (when public) and privacy statements. Where we could not test something, the review says so.
Scoring
Six criteria, each scored 0–100 by two editors independently and averaged: format support, ease of use, speed, encryption and security, price and value, support and updates. The overall rating is a weighted average on a five-point scale.
Corrections
Email corrections to the address below. Material corrections are noted at the bottom of the page with the date.
Updates
Reviews are re-checked at least twice a year and whenever a developer changes pricing or ships a major version.
