Microsoft Publisher is a desktop publishing program that is included with Microsoft Office 2010. Opening Publisher files can be performed on the Mac by changing the file extension to a format that a Mac program can open. If you own Microsoft Office for Mac, you can change the extension to a .doc or .docx format. If you do not own Microsoft Office for Mac, you can change the extension to .txt, .rtf, HTML or Unicode formats. These formats can be opened using TextEdit, which is the default Mac word processing program.
Click "File," then "Save As" on the Windows version of Publisher.
Click the drop-down menu next to "Save as type:" and select an extension that can be read on word-processing software on the Mac. The Publisher program can save files in .txt, .rtf, HTML formats, Unicode text, and Word .doc and .docx formats. Click the "Save" button after you have selected the format you want.
Transfer the file from your Windows computer to your Mac computer by e-mailing the file to yourself or using an external memory device such as a flash drive.
Open the word processing software on your Mac. Most Macs come pre-installed with TextEdit, which can open .txt and .rtf file formats.
Click "File," then "Open." Search for the file you wish to open, select the file, then click "Open."
