The Mailvita PST to EML Converter for Mac enables users to convert PST files into EML format without data loss. The utility lets users choose particular PST files or folders for export, hence supporting selective conversion. From To, From, Cc, Bcc, subject, and attachments, it preserves the email structure and metadata throughout the process. It runs without Outlook installation and supports all main macOS versions. Those moving from Outlook to Windows Live Mail, Thunderbird, or another EML-supported email client will find it particularly helpful. Users are capable of working with both Mac and Windows OS with no restrictions.
