Adobe PageMaker was desktop-publishing software from Adobe. PageMaker 4 for Mac used ALD4 files for documents containing page layouts and their associated text and graphics references.
The format is intended for the Macintosh version of PageMaker 4 and is now a legacy format. Modern versions of macOS do not normally run the original software, so opening an ALD4 file may require an older compatible Macintosh environment.
Open the .ald4 file with Adobe PageMaker 4 for Mac. Because this is a legacy Macintosh format, the original program may need to be run on a compatible older Mac or in a suitable classic Mac environment.
If the file opens in PageMaker or a compatible later PageMaker version, use that application to save or export the document to a more current format, such as PDF.
