I only got to install it on Ubuntu, as for any reason in MacOS X it never finds “vMac.ROM” file inside the same folder.
Installing and configuring Mini vMac
1. Download latest version from official link
2. Expand archived file
2. Download ROM file “vmac.rom” from this link
https://sites.google.com/site/minivmacapplicationsv6/disk-images-and-roms
3. Place “vmac.rom” in the same folder as where minivmac executable has been placed.
4. Rename “vmac.rom” to “vMac.ROM”
Running and launching Mini vMac
1. Open minivmac executable. A floppy disk with a question mark must be displayed.
2. Drag and drop a .dsk file (bootable image) to the minivmac window.
Dragging and drop a .dsk file to this window would be as inserting a floppy disk.
Extracting files from Mini vMac
1. Download program
