Mac software was historically distributed on 3.5-inch floppy disks. Today, you can read these disks on modern Windows computers using the MacDisk utility.
When the Macintosh debuted in 1984, it lacked any form of mass storage, such as hard drives or SSDs, relying instead on a 3.5-inch floppy disk drive developed by Sony. Before the widespread availability of the Internet, software for personal computers was commonly sold through floppy disks, progressing from 8-inch floppies to 5.25-inch disks used with the Apple II and IBM PC, and finally to the 3.5-inch disks.
Steve Jobs made a special trip to Japan to negotiate with Sony for the rights to use the 3.5-inch drive in the Macintosh. Although Apple considered a dual 5.25-inch floppy model for the Mac, this idea was ultimately scrapped.
Instead, they released external floppy drives with capacities of 800K and 1.44MB that connected through a proprietary Apple connector. Users often faced the inconvenience of constantly swapping floppies to access both the operating system and applications.
The Macintosh SE was the first model to incorporate an internal SCSI hard drive along with an internal floppy drive, enhancing user accessibility. Although some later SE models offered dual floppy drives, the transition to modern storage formats began in the late 1990s when Apple ceased including floppy drives in their Macs.
Early Macs used a proprietary disk format, complicating file transfers between Macs and PCs. Although some third-party solutions emerged, such as AccessPC, and Apple released its own PC Exchange software, transferring files from Mac to PC remained challenging due to differences in file architecture.
Today, utilities like MacDisk allow users to access vintage Mac disks on modern Windows systems, although it primarily supports the later 1.44MB floppies. Apple stopped including floppy drives in the mid-to-late 1990s, leading to the introduction of external USB floppy drives, which can be used with contemporary Macs.
MacDisk is straightforward to install and use, enabling users to read, write, and format Mac-compatible 3.5-inch floppies. It offers additional features such as the ability to create new Mac disks from existing content, making it a versatile tool for accessing vintage Mac software.
