Infinite Mac is a collection of classic Macintosh and NeXT operating systems and software, all easily accessible from the comfort of a web browser.

Pick any version of System Software, A/UX, NeXTStep, Mac OS, BeOS or Mac OS X from the 1980s, 1990s or early 2000s and run it within a virtual machine. An “Infinite HD” disk with representative software from that era is also available. You can also run a custom version with your choice of machine and disks. On some operating systems files and disk images can be imported and exported using drag and drop and virtual CD-ROMs can be mounted – refer to the welcome screen in each machine for more details.

You can learn more, embed instances into your own site, monkey around, see what's changed recently or donate to support this project.
