![]() ![]() By default, the operating system will refuse to run applicationsdownloaded from the internet, unless Apple considers it trustworthy(because it is digitally signed by a developer registered with Apple).Gatekeeper is in some ways a good idea, but some people consider it asone step along the way to making OS X like iOS, where no softwarecan be installed without Apple's permission, and emulators areforbidden, including Mini vMac. The other issue is caused by Gatekeeper, added in OS X Mountain Lion(10.8). Another option is to tell macOSnot to do Path Randomization for Mini vMac, using the xattr command,as described in more detail below. One work around is to put the imagein one of the other places that Mini vMac looks, as describedin the ROM sectionof the Emulated Hardware Reference. The silly way that Applehas chosen to prevent this is to in effect move the applicationsomewhere else before running it, so it can’t find the library code.It can’t find anything else in the application’s folder either, whichis a problem for Mini vMac, which looks for things in its folder,such as the ROM image file. This is fundamentallyincompatible with the Mini vMac Variations Service (which needsto finish in a few seconds), and is anyway disturbing.Fortunately, for now at least, using the xattrcommand will allow Mini vMac to run without notarization.Ī second issue is caused by Path Randomization,added in macOS Sierra (10.12).If an application that Apple thinks is trustworthy is bundledtogether with malicious library code in the same folder, themalicious code may be run by the application. Starting with macOS 10.14.5, Apple wants software to be“notarized”, which involves sending it off to Applefor their computers to inspect and sign it. Quick Fix : run “xattr -cr ” inthe terminal. Source: RetroMacCast Image: All photos by John Leake, used with permission.There are three issues in recent versions of OS X that causeproblems for Mini vMac. When can we order one? Leake with his newly birthed creation. More info is available in the latest RetroMacCast, which is rapidly approaching its 300th episode! Nice work, John. “It’s not as bad as I thought,” he says, “especially since to get Mini vMac to run at full screen I had to adjust the boot config file to get it to output at 512×384, which is then being shoved onto a screen with a resolution of 320×200.”Īnother video gives more details of the design and shows the Mini Mac in action (there’s no sound, apparently the audio output of Mini vMac on the Raspberry Pi is a bit glitchy): Leake was worried the tiny screen would be completely unreadable, but things turned out OK. On top of this is the Mini vMac emulator running System Software 6.0.8. On the software side, the Raspberry Pi is running Rasbian, a modified version on Debian Linux. Back in 2010 he converted a Mac Plus into the infamous Banana Junior from the comic strip Bloom County. This may be the only Compact Macintosh in the world with an HDMI output port!Ĭustom creations are nothing new to this Mac über-fan. The last thing I had to do was to solder wires directly to the Pi board to bypass the power connector.” The rear case sports two USB ports, an HDMI port, and an ethernet jack. I also had to cut away quite a bit of the USB cable on the top to get it to bend below the top of my case. “On the Pi, I had to cut the SD card down almost flush with the edge of the Raspberry Pi board. To make everything fit, Leake had to make a few modifications. On top is a two-port USB charger that powers the Raspberry Pi and the monitor. One of the inside ports holds a Wi-Fi dongle, the other a Bluetooth dongle. The cramped innards contain a Raspberry Pi (left), a few USB hubs and power supplies. Two USB ports are facing out and two facing in. The Raspberry Pi (aka “the motherboard”) sits on the left next to a four-port powered USB hub. ![]() ![]() The monitor is a 3.5-inch composite LCD panel, held in place with two brackets and a few Velcro tabs. Mini Macintosh next to the full-size model. If he decides to make more of these super-cute miniscule Macs, he may employ a 3D printer rather than manually crafting elements. The sides, bottom and front were glued together to make one piece and the top and back a second piece.ĭuring the podcast discussing Mini Mac, Leake notes that the assembly took about twelve hours total. He then used files and sandpaper to shape the bezels, with extra care taken around the curves near the screen. Leake made the case using sheets of PVC plastic ( white 3M Sintra) which yields easily to an X-Acto knife.
