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.
