Space Broccoli Mac OS
macOS Big Sur was officially released for all users in November last year, and since then Apple has released updates with bug fixes and overall improvements. However, as reported by Mr. Macintosh, Big Sur still has a serious issue that can result in data loss when users try to upgrade a Mac to the latest version of the operating system without enough space available.
Plant broccoli during the cool weather of early spring and fall. Grow it in containers or an in-ground garden. Space broccoli plants according to the label (usually 18 inches apart). Choose a location with full sun, easy access to water, and fertile soil with a pH between 6.0 and 7.0. Purgeable space mainly consists of local snapshots which your Mac makes periodically. It also contains sleep images, caches and temporary system files. DaisyDisk can locate and delete these files instantly. When you complete a scan of your hard drive with DaisyDisk, you’ll see a sector called “Hidden space”.
After noticing several reports from users on the web, Mr. Macintosh found out that the macOS Big Sur installer isn’t checking whether the Mac’s internal storage has enough free space. As the system initiates the update process, the Mac becomes unresponsive, and data can be permanently corrupted.
Apple says upgrading to macOS Big Sur for the first time requires at least 35.5 GB of available storage — and this doesn’t include the 13 GB macOS Big Sur installer. Unfortunately, even if your Mac does not have 35.5 GB of storage available, macOS will try to install the Big Sur update, and that’s when users may lose all their data.
The update process seems to run perfectly, but users get the following message near the end of the installation:
An error occurred preparing the software update.
From that point on, the Mac will no longer boot. Mr. Macintosh was able to confirm that this bug affects macOS Big Sur 11.2 installer and even macOS Big Sur 11.3 beta installer. At the same time, this doesn’t affect OTA updates from one Big Sur installation to another (such as updating from macOS 11.1 to macOS 11.2).
If you have a backup of your data, you can simply erase the entire disk and reinstall macOS. However, recovering data without a backup can be very difficult.
With FileVault enabled, you have to connect your Mac to another Mac via Target Disk Mode in order to recover your files. If FileVault wasn’t enabled on your Mac, you can try to delete some files using the Terminal app in macOS Recovery, which will allow macOS to complete the update process successfully.
Apple hasn’t commented on this bug so far, but hopefully it will be fixed with the final release of macOS Big Sur 11.3. You can read more details about this problem on the Mr. Macintosh blog.

Last year I began fiddling around with a program called A-OK! The Wings of Mercury, a computer program written by Joe Nastasi that completely simulates a Mercury space mission from the 1960s. Nastasi realized that today’s computers are sufficiently advanced that they can replicate not only the interior of a Mercury capsule and simulate its flight in video-game quality detail, they can also simulate the entire Mission Control Center.
A restricted-feature version is available for download. Paying the registration fee gets you a code to enable the missing features, which include networking a room full of Macs together as a mission control center.
Installation is straightforward. The program runs on both OS 9 and OS X. System requirements are fairly moderate – you need a G3 (333 MHz for OS 9, 600 MHz for OS X, OS X 10.7 and newer not supported) and you must have a video card that handles QuickTime RAVE (OS 9) or OpenGL (OS X).
I’ve run the program on both OSes, and it works identically. A faster processor helps, but it ran reasonably well on a 300 MHz Beige Power Mac G3 tower – well enough for me to use it as my primary machine for the simulation at school. Even though it was a bit under the recommended requirements on the website, it ran well.
On a 1 GHz TiBook it was extremely smooth in animation, although there was a small problem with the 3D rendering leaving an artifact above the rocket in flight when your point of view was below the plane of the rocket (from underneath, the screen shows a vertical bar above the rocket).
Aside from that, the program runs great, the documentation is excellent (although I have some suggestions noted below), and the simulation is fun. If you have the slightest interest in the history of space flight, simulation, applied physics, or rocketry, you will love this program. Try it out, pay for it, use it. We purchased the site license from some grant funds we used to develop curriculum for our space academy courses.
The program essentially recreates the interior of a Mercury space capsule, down to the last switch. Just to give you a comparison, here is a screen shot of the primary control panel.
For comparison, here is a screen shot of a Mercury capsule mockup exhibited at the Chabot Space center in Oakland, California this month:
Can you spot the missing indicator instrument? My students have to describe the differences between these two pictures as part of an assignment.
The question that remains for me as an educator is what do you do with this software? Do you just turn kids loose on it or do something organized?
If you run the simulator as is, there’s not a lot for students sitting at the Mission Control Center consoles to do. That’s not a flaw in the program; it’s just the nature of working at Mission Control.
Your job at Mission Control in this simulation, if you were to do the job right, would be to call for holds as necessary before launch; abort if conditions warrant; report on values of such things as fuel supply and blood pressure according to your schedule or if asked.
Space Camp in Huntsville, Alabama, solves this problem by carefully scripting a launch. When you attend Space Camp (and they have versions for teachers, adults, and whole families) you get a binder with step-by-step instructions and words to read for each person. There’s not much decision-making involved, but then you only get a couple of days to prepare for the simulated mission.
A-OK could benefit from a scripted manual for beginners that not only tells what buttons to push but what to say along the way.
Here is what my classes did this year, because I did not have time to write such a scripted manual.
First, I ran the simulator in automatic mode for a sub-orbital flight. As the program displayed on my projector screen, I talked students through the terms on a vocabulary puzzle I provided for them. They learned BECO (Booster Engine Cut Off), the name of the first American in space (Alan Shepherd), and the name of the base of the capsule (the heat shield).
After that, I gave them a packet that asked them to fill in the steps of a launch according to the timeline provided in the program’s help files, estimate the model rocket engine code that a Mercury Redstone would be rated, and guess what stations are which in a photograph of Mercury Mission Control based on the Mission Control Center simulator.
While most of the class worked on the packets, I had volunteers attempt to run through the simulation manually. That worked well, although there were a few buttons and switches that we couldn’t find or were not labeled as they appeared in the checklist (oddly enough, we could not find the Abort Handle in step one), and twice students pulled out the oxygen snorkel while trying to see if it was in the proper position during a countdown – and then discovered it wouldn’t go back in.
Eventually I changed the setup to give a little more realism by connecting an old joystick to the computer for maneuvering thruster control (which worked once I got the settings figured out for my stick – they were conflicting with the mouse when the Finder was running).
I installed two extra video cards in the PCI slots of the Beige G3 and ran three monitors – one for the astronaut, one with the clock (for me), and one with the external view and view through the window (for the class). Performance took a hit, but not so much that we couldn’t enjoy the simulation. And this was on a machine below the minimum system requirements. Pretty impressive for a REALbasic application.
I learned enough this year that we may take things a step further next year and hold astronaut applications and plan a mission from start to finish (I’ll supply the freeze-dried astronaut ice cream for the in-flight snack).
We could have done a little more with it if I had started earlier. There’s a lot of physics and math buried in here – projectile motion, Newton’s Laws, orbital mechanics, ellipses, speed-distance-time problems, logistics, nutrition, and more.
Overall, I think this is a great package and plan to use it in the future. Even though it didn’t quite capture the attention of that girl in the back who just talks constantly and does makeup when she’s not talking, everyone else enjoyed it (especially when we crashed).
