Use LibreOffice to Access .doc and .wpd Files on a Mac
As a Mac-using lawyer, I often have to solve the problem of how to work with legacy file formats. An awful lot of very good attorneys have done very good work using programs like Microsoft Word (.doc) and WordPerfect (.wpd). When these attorneys are kind enough to send me their pleadings and letters and research outlines in these formats, I use LibreOffice to open them on my Mac.
From there, I can plagiarize the work of other, smarter attorneys into my new Pages document. (A few years ago, I switched from Word for the Mac to Pages due to stability issues.)
LibreOffice is a project of the The Document Foundation (which has created office productivity programs for spreadsheets and presentations, as well). If you download LibreOffice, I highly recommend you donate to support the Foundation (though I have tried twice in the past few weeks (so that I can practice what I preach here) only to have the process of donating fail...doh!).
