OTRUtility 0.2.1 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software lies within System Tools, more precisely File Managers. This free Mac app is a product of Oliver Langer. We recommend checking the downloaded files with any free antivirus.
