macOS cannot open PST files. They are a Microsoft format, and without Outlook for Windows there is no built-in way to read them. MailRaider Pro fills that gap — it opens PST archives directly on your Mac, no Microsoft software required.

Drag your PST file onto MailRaider Pro and it opens immediately. You get the full folder hierarchy from the archive — Inbox, Sent Items, and any folders and subfolders that were set up in Outlook — with all email displayed exactly as it was originally composed, including formatting, embedded images, and attachments.

From there you can:

What you can do	How
Browse the full folder hierarchy	Double-click any folder to navigate into it; double-click .. to go back up
Sort email by sender, subject, or date	Click any column header in the email list
Search across the entire archive	Type in the search field — searches subject, sender, recipient, and body text
Read any email in full	Double-click the row, or click the magnifying glass icon next to its name
Save attachments	Open the attachments drawer and drag files out, or select and click Save
Export to Apple Mail or Thunderbird	File > Export > MBOX — folder structure is preserved in the export
Export to PDF, EML, or XML	File > Export — bulk export applies to the current selection or folder
