This week’s support document looks to answer the following questions:
What are the possible combinations for the internal drives on a Macintosh SE and SE/30?
Turns out, there are a lot of them:
The Macintosh SE chassis is capable of holding two 3.5-inch storage devices. The Macintosh SE and Macintosh SE/30 logic boards use the same amount of space in the Macintosh SE chassis. The Macintosh SE/30 logic board has only one internal floppy-drive connector.
Just look at this glorious list of possible combinations:
- Macintosh SE logic board; one 800K floppy drive.
- Macintosh SE logic board; one Apple SuperDrive (formerly Apple FDHD).
- Macintosh SE logic board; two 800K floppy drives.
- Macintosh SE logic board; two Apple SuperDrives.
- Macintosh SE logic board; one 800K floppy drive, one 3.5-inch hard drive.
- Macintosh SE logic board; one Apple SuperDrive, one 3.5-inch hard drive.
- Macintosh SE/30 logic board; one 800K floppy drive.
- Macintosh SE/30 logic board; one 800K floppy drive, one 3.5-inch hard drive.
- Macintosh SE/30 logic board; one Apple SuperDrive.
- Macintosh SE/30 logic board; one Apple SuperDrive, one 3.5-inch hard drive.
This week on MPU:

Loren Grush at The Verge:
After nearly two decades of effort, Elon Musk’s aerospace company, SpaceX, successfully launched its first two people into orbit, ushering in a new age of human spaceflight in the United States. The flight marked the first time astronauts have launched into orbit from American soil in nearly a decade, and SpaceX is now the first company to send passengers to orbit on a privately made vehicle.
The two astronauts — veteran NASA fliers Bob Behnken and Doug Hurley — rode into space inside SpaceX’s new automated spacecraft called the Crew Dragon, a capsule designed to take people to and from the International Space Station. Strapped inside the sleek, gumdrop-shaped capsule, the duo lifted off on top of SpaceX’s Falcon 9 rocket from NASA’s Kennedy Space Center in Florida at 3:22PM ET on Saturday. The rocket dropped the Crew Dragon off in orbit about 12 minutes later. Now, the pair will spend roughly the next day in orbit before attempting to dock with the International Space Station on Sunday morning.
A new era of spaceflight is here.
Adi Robertson at The Verge, writing about Trump’s executive order concerning how Twitter, Facebook and others should moderate user content:
The order follows a feud with Twitter after it fact-checked one of Trump’s tweets, but it’s been brewing since at least 2019 when a social media “bias” rule was rumored but never revealed. An unfinished draft of the order leaked on Wednesday, full of nonsensical demands and pointless blustering, with many dismissing the rule as simply illegal.
But the final order released yesterday is significantly different from that draft — and a good deal more troubling. It’s still a tangle of vaguely coherent bad rules, legally baffling demands, and pure posturing. But it’s easier to see the shape of Trump’s goal: a censorship bill that potentially covers almost any part of the web.
Spend some time this weekend looking at this.
SpaceX had just conducted yet another static fire test of the Raptor engine in its Starship SN4 prototype launch vehicle on Friday when the test vehicle exploded on the test stand in Boca Chica, Texas. This was the fourth static fire test of this engine on this prototype, so it’s unclear what went wrong vs. other static fire attempts.
This was a test in the development of Starship, a new spacecraft that SpaceX has been developing in Boca Chica. Eventually, the company hopes to use it to replace its Falcon 9 and Falcon Heavy rocket, but Starship is still very early in its development phase, whereas those vehicles are flight-proven, multiple times over.
This rocket has nothing to do with the Falcon 9 poised to take American astronauts Douglas Hurley and Robert Behnken to the International Space Station. That flight will mark the first time astronauts have left Earth from American soil since the space shuttle program ended nine years ago. Still, not great timing for the company.

Mike at Bombich Software, the makers of the excellent Carbon Copy Cloner, writing about a change in the newest version of Catalina:
Early last week we discovered an APFS filesystem bug in a beta of macOS 10.15.5. The technical details of the bug are laid out below, but the short version is that we’re no longer able to use our own file copier to establish an initial bootable backup of a macOS Catalina System volume. To be very clear – existing backups are unaffected, and this has no effect on CCC’s ability to preserve your data, nor any effect on the integrity of the filesystems on your startup disk or your backup disk. The impact of this bug is limited to the initial creation of a bootable backup.
Check out the full post for the technical details, but in short, it’s hard to tell if this is a bug or a change in Apple’s security policy concerning the Mac. If it’s a bug, I have questions about what sort of change could impact this toward the end of an OS’ active development, and if it’s a change, it should have been documented when it first shipped in the beta.
This week on Connected:
Stephen keeps trying to make #GreenGate a thing, Federico has a new friend and Myke has large lungs. Then, an in-depth conversation about what should come next for Shortcuts.
There’s a real tension in Shortcuts between being an app for everybody, and an app for power users.
