Thanks everyone for the software suggestions, I've added a few to Infinite HD (and also some CD-ROMs to the drawer). This includes SheepShaver, so you can emulate a Mac while emulating BeOS while running in a browser virtual machine. Runs best on more recent […] [Original post on hachyderm.io]

Extended Infinite Mac's screenshot function to do screen recordings too. You can now dissect zoom rects and other Mac animations frame-by-frame at your leisure. There's also a keyboard shortcut (Command-Option-Shift-2).

I've started to add BeOS to Infinite Mac - you can see the first few versions on infinitemac.org/?filter=beos Not having been much of a user back in the day, I'm looking for suggestions of software to make sure to include, or pointers to canonical […] [Original post on hachyderm.io]

Infinite Mac now has a built-in screenshot function, making it easier to do a full-fidelity capture of what's on the emulated Mac's screen. Enjoy the jaggies! (thanks to @michaelsteeber for suggesting this feature)

I've switched over Infinite Mac's classic Mac emulation to @twvd's awesome Snow, which unblocks A/UX emulation: infinitemac.org/?filter=aux There's a behind-the-scenes blog post at blog.persistent.info/2026/09/infini… detailing this and other site updates.

The Macintosh Garden is an amazing resource, but it can give Russian nesting doll vibes when installing software - apps inside of disk images, inside of StuffIt archives, etc. Inspired by @nulleric's What the .SIT?! site (bluescsi.com/what-the-sit) […] [Original post on hachyderm.io]

The Mac Classic had an usual feature where you could boot it from ROM (i.e. without an internal startup disk) all the way to the Finder. For fun I've made it an optional feature of Infinite Mac […] [Original post on hachyderm.io]
Mac Classic as emulated by Snow running inside of Infinite Mac. It has been booted from its ROM by holding down Command-Option-X-O at startup."Brought to you by" folder in the Mac Classic ROM Boot Disk. It contains Bruce Leak, Gary Davidian, Gary Rensberger, and additional folders for the hardware and software teams.

I’d spotted a few “Infinite HDs” lurking in screenshots in David Pogue’s _Apple: The First 50 Years_ - it was great to see this callout at the end.

Why should mobile have all the fun? I also added a full-size keyboard for desktop use, in case you want to trigger harder-to-replicate combos like Command-Shift-3 or Command-Power (for MicroBug and/or MacsBug)

Playing around with adding BlueSCSI Toolbox protocol support to DingusPPC. Though somewhat roundabout, the end result is that you can transfer files in and out of more emulated machine types on Infinite Mac. As a bonus, it also makes the Macintosh Garden library […] [Original post on hachyderm.io]

Classic Mac's OS file system innovations (resource forks, metadata) were often lost in transit when the Internet took off in 1995, and the same is still true 30 years later in Infinite Mac. I figured out a workaround using modern macOS's built-in .zip archives […] [Original post on hachyderm.io]
