Looking back, we realize that there have been several versions of the systems we use today. The evolution has been fantastic and the systems are increasingly more robust and intelligent.
macOS 8.1 works perfectly on Windows, Linux and macOS
It's been 29 years since the launch of macOS 8.1. With technology and innovation from the 90s, Apple's system ran apps like Photoshop 3, the web page development kit, Premiere 4 and several games, including Duke Nukem 3D, Alley 19 Bowling and Dungeons and Dragons.
These apps and games are also available in this new app that occupies only 250 MB and, despite some limitations, is fully operational.
Compared to current machines, macOS 8.1 also doesn't need a lot of hardware resources (at the time, Apple machines had Motorola GPUs). Felix Rieseberg also says that with this version of the system it is even possible to transfer files and mount disc images.
The virtual machine emulates a 1991 Macintosh Quadra 900 with a Motorola CPU that Apple used before switching to the PowerPC architecture.
Unfortunately the system does not allow users to connect to the internet, however, the Internet Explorer and Netscape are installed as well as the “Web Sharing Server” for those who want to play. This virtual machine is available for machines with 32-bit and also 64-bit architecture.
