During my stay in Melbourne, with only my Macbook Air, I had no access to Astrolog, my go-to software tool for astrological analysis. Let's recall that the usual Windows emulation software doesn't work on the new Silicon Macs. Having returned to home base, I've been able to install Astrolog on my old 2013 Macbook Pro using Bottles.

USB Drive Difficulties
![]() |
|
Here is a little interaction that I had with Gemini concerning my USB drive difficulties:
Question:
Is there a free disk utility that I can download that will resurrect my USB memory stick? Apple's disk utility will not reformat it and it is quite new, having been used only a couple of times since purchased a month ago. I used the software tool "balenaetcher" to turn my USB memory stick into an Ubuntu boot disk for a mini-PC that I had been given. As a boot disk it did its job of installing Ubuntu on to the mini-PC but after that I wanted to reformat it so that I could use it to back up files on my Macbook Air. However, it is this reformatting that I've been unable to carry out.
Response:
This is a very common and frustrating problem when using tools like balenaEtcher. The reason this happens is that balenaEtcher doesn't just copy files; it writes an entire image to the USB stick, which includes a different type of partition scheme (like the one used for Linux boot drives). This can make the disk appear to have multiple, small, or unreadable partitions that macOS's Disk Utility has trouble with, especially if it's set to the default "Show only Volumes."
Fortunately, there are several powerful, free methods you can use to "resurrect" your USB stick. Since Disk Utility isn't working for you, here are the most effective alternatives:
1. The Terminal Method (Most Recommended)
This method is the most direct and powerful way to completely wipe the disk and create a new partition map that Disk Utility can understand. It's essentially a more forceful version of what Disk Utility tries to do.
Step-by-step instructions:
Open Terminal: You can find it in
Applications > Utilities > Terminalor by searching in Spotlight (Command + Space).List your disks: Type the following command and press Enter:
diskutil listThis will show you a list of all connected drives and their identifiers (e.g.,disk0,disk1,disk2).Identify your USB stick: Look for a disk with the correct size. For example, if your USB stick is 32GB, you'll see a line that says something like
/dev/disk2 (external, physical)and lists its size. Be absolutely certain you have the right disk number! Wiping the wrong disk could erase your Mac's internal drive.Erase and reformat: Once you've identified your disk (let's assume it's
disk2), use the following command. This command will first unmount the disk, then erase it completely, create a new GUID partition map, and format it as exFAT with a new name.diskutil eraseDisk ExFAT "MyUSB" GPT /dev/disk2
eraseDisk: The command to erase and format the disk.
ExFAT: The file system format you want to use. You can also useFAT32if you prefer.
"MyUSB": The name you want to give the drive.You can change this to anything you like.
GPT: The partition scheme. This is a modern, highly compatible standard.
/dev/disk2: This is the crucial part. Replacedisk2with the identifier you found in step 3.Press Enter and let the command run. If it's successful, you'll see a series of messages confirming that the disk was unmounted, partitioned, and formatted.
2. GParted (Linux-based Solution)
If you have access to another computer or are comfortable with running a live Linux environment, a tool called GParted is a very reliable way to fix this. It's a graphical partition editor that is often more robust than macOS's built-in tools for dealing with non-standard partition layouts.
Create a new bootable Linux USB: Since your current USB stick is non-functional, you'll need another one. Use balenaEtcher again to create a bootable USB with a lightweight Linux distribution like GParted Live or a minimal version of Ubuntu.
Boot your mini-PC from this new USB: Start your mini-PC from the GParted Live USB.
Run GParted: GParted will automatically launch.
Select your faulty USB stick: In the GParted interface, select your original, faulty USB stick from the drop-down menu in the top right corner.
Create a new partition table: Go to
Device > Create Partition Table. Choosegpt(GUID Partition Table).Create a new partition: Right-click on the "unallocated" space, choose
New, and create a new partition with the desired file system (e.g.,exfatorfat32).Apply the changes: Click the green checkmark to apply the changes.
Re-attempt on your Mac: After this, the USB stick should be fully readable and writable on your MacBook Air.
Why did balenaEtcher cause this?
BalenaEtcher's job is to create a byte-for-byte copy of a bootable image to the USB drive. This process overwrites the entire drive, including its partition table and file system. The Ubuntu image you used has a different partition layout (often with multiple small partitions for things like EFI and the bootloader) that macOS's Disk Utility doesn't always handle gracefully, especially when trying to "erase" it in the typical way. The Terminal and GParted methods are more powerful because they completely destroy the old partition table before trying to create a new one, which is exactly what's needed to fix this issue.
Fortunately, the first method proposed by Gemini (using the terminal) worked and all is well again. I've included the information in this post as a reminder in case I encounter a similar problem in the future.

Macbook Air M1
Having acquired a Macbook Air M1 for my birthday, I set about getting Astrolog to run on it under Wine. I succeeded under Linux but it's proving frustrating using the Macintosh operating system running on the newer non-Intel chip. I've had Astrolog running quite happily on my 2013 Macbook Pro when the Mac OS was installed. The error message when trying to get WINE to run the astrolog.exe mentions "bad CPU type" so the newer CPU seems to be the problem.
There is a Macintosh version but it only seems to work in the terminal and produces output as shown in Figure 1. As the documentation says:
The main difference from the Windows version is that it does not offer a Graphical User Interface, and so you will not find a mouse-driven menu system or dialog interface. However, it offers just about everything else. You can even draw temporary squiggles/annotations with your mouse ona chart displayed in X11.
This is clearly of limited use and takes me back to the bad old days of the late 1980s using MS-DOS on a 286 PC.

Figure 1 |
I have installed WINE on my Macbook Air but it will not run astrolog.exe. I keep getting an error message. Here is what it says. If you can understand it, you're a better man than me (I then copied the entire error message).
The error message you provided indicates an issue with running astrolog.exe using Wine on your Apple Macbook Air with M1 chip. Here's a breakdown of the error and potential solutions:Understanding the Error:
"Bad CPU type in executable": This is the core issue. Wine expects a program compiled for a specific CPU architecture (likely x86 for traditional computers). However, your Macbook Air uses an M1 chip with ARM architecture, which is different. Astrolog.exe is likely compiled for x86 and incompatible with your Mac's CPU.Why Wine Doesn't Work with M1 Macs (for now):Wine typically translates instructions from Windows programs to work on the underlying system's architecture. However, M1 chips are a significant departure from Intel x86 architecture, and full compatibility with Wine is still under development.Possible Solutions (Limited)There are unfortunately no guaranteed solutions to run astrolog.exe directly on your M1 Mac with Wine at this time. Here are some possibilities to consider, but keep in mind their limitations:Alternative Software: Explore if there are alternative astrology software programs that are native to macOS or have web-based versions.Crossover (Paid Software): Crossover is a commercial alternative to Wine that attempts to run Windows applications on macOS. It might have better compatibility with M1 Macs than the free Wine version, but there's no guarantee it will work with astrolog.exe specifically.Virtualization with Windows on ARM (Experimental): There are ongoing efforts to run Windows on ARM processors through virtualization. While Microsoft does offer a limited preview of Windows 11 for ARM on compatible devices, it's still in development and might not be suitable for everyday use yet.Recommendation:Since Wine isn't a reliable option for astrolog.exe on your M1 Mac at this point, investigating alternative software or waiting for potential future compatibility improvements in Wine or virtualization solutions might be the best course of action.
Of course, there's paid astrology software for the Mac but I've gotten used to using Astrolog for free over many years and it does all I need it to do.

WiFi Connectivity Problems with LinuxMint
I found that if I use my laptop in the bedroom where the signal strength is about 50% then the WiFi constantly prompts me for the password which should be automatically stored. Once supplied, I'm often prompted again and again and again. Sometimes it's satisfied but only for a while, then the prompts begins again.
The problem doesn't occur as much where the signal strength is stronger. I turned to Linux Forums and discovered the following suggested fix:sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*
echo "options rtl8723be ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
After entering this into the terminal and rebooting, all seems well. No more prompts. Fingers crossed that the problem doesn't recur. Oops, just as I typed this the problem did recur. Well, sort off. The connection dropped briefly and then restored itself without prompting me for a password. I can handle those sorts of transient disruptions if they're not too frequent.
What I'll do is to get on with my normal workflow and I'll report back on what's transpired in an hour or so. It's now 10:51pm ... so it 12:14am and the WiFi did drop out a couple of times but it soon reconnected and I was never once prompted for my password. While things are not ideal, I must say that overall I can live with the current minor disruptions.

Installation of Linux Mint 20.3
You can't say that there's no technological excitement in my life. I finally had to abandon the use of Ubuntu on my 2013 MacBook Pro. The keyboard, trackpad and mouse freezes were becoming too frequent and numerous reboots were required to activate these devices. Finally no amount of rebooting could activate them and so I turned to Linux Mint.
The installation went smoothly enough but the boot up process was, and continues to be, interrupted by a series of error messages. That is a minor irritation but far worse was to come. I discovered that the OS didn't recognise the WiFi adapter in the laptop. So, for the moment, no WiFi but thankfully I have an Ethernet connection. I had an old TP-LINK WiFi dongle that must be at least a decade old and I tried that out but no luck. Perhaps a can buy a more up-to-date dongle that works. This is a matter for deeper investigation but for the moment, as long as the keyboard, mouse and trackpad don't freeze up on me, I'll be happy.
My initial attempt to install the Chrome browser failed but then I was reminded that flatpak is built into Linux Mint and, by using that, the installation of the Chrome browser and also Calibre was straight forward. So far, after a couple of days of using Linux Mint, I've had no problems and I hope things stay that way.
I've put out a request for help on the Linux Mint Forums and hopefully help will be forthcoming. So far 20 views but no comments. However, it's been up less than an hour.

Ubuntu: Reinstallation
I really do need to remember that, the next time my mouse, keyboard and trackpad freeze, I should try holding down the option key while rebooting and then choose the only boot option available. Last time I did that I regained full functionality. However, just recently I forgot to do that, and instead reinstalled Ubuntu with all the problems that inevitably entails.
I did try to reinstall Mac OS but that didn't get far. Figure 1 shows the error message. Numerous attempts failed. I was using an Ethernet connection and not WiFi for the download but still it failed. The Time Machine was an option but I long ago abandoned that method of backing up. It was probably for the best as I'm sure the laptop would have been overly sluggish.

The Experiment Is Over
It was exciting while it lasted but after a few days, the flaws began to outweigh the attractions. I'm taking about the installation of Chrome OS Flex to replace the Mac OS on my 2013 Mac Book Pro. In summary, the defects of the installation included:
- a frustrating time lag between opening the lid of my laptop and seeing an active screen: I never timed this precisely but it started to get under my skin because I would stare at a blank screen for what seemed like a minute or more and no amount of key presses would make a difference.
- unresponsiveness of the track pad: having long abandoned a mouse when using my laptop, it was frustrating to have to rely on a mouse again but it was necessary as the pointer would become unresponsive every few seconds. This rendered it virtually unusable. Worse still, once I connected the laptop to an external monitor, even the mouse became "twitchy".
- total lack of support for Linux: even though I'd apparently installed Linux, there was no way to open to get a functioning terminal window. I was always confronted with an error message and so no installation of Linux apps was possible.

Chrome OS Flex Update
Having installed Chrome OS Flex on my 2103 Mac Book and replacing the Mac operating system, I've been using it successively to carry out my everyday tasks. On the plus side, the WiFi glitch that so bedeviled my Mac with the old operating system has gone. The problem arose when I tried to access the WiFi from a repeater. I would get an IP conflict error message. Not anymore.
On the negative side, the touch pad remains problematic. The pointer works but sometimes is not responsive for a few seconds and this makes it impossible to use for sustained periods of time. Fortunately the mouse works just fine. However, when connected to an external monitor, the mouse becomes "twitchy" and suddenly jumps from the laptop screen to the external monitor. This becomes quite an irritation when using dual screens for extended periods of time.
I've tried to download Linux but so far I've not been successful. Figure 1 shows what happens.
| Figure 1 |
Setting up a recovery image on my USB drive also fails as can be seen in Figure 2.

I don't print anything so I've no idea what problems there are with printing. I would suppose many but fortunately that's not an issue for me. I've learned about PWAs or Progressive Web Apps, defined by Wikipedia as:
A progressive web application (PWA), commonly known as a progressive web app, is a type of application software delivered through the web, built using common web technologies including HTML, CSS, JavaScript, and WebAssembly. It is intended to work on any platform that uses a standards-compliant browser, including both desktop and mobile devices.I've set one up for Twitter so that I'm saved from needing to open it via the browser. Here is some additional information from Wikipedia:
In 2017, Twitter released Twitter Lite, a PWA alternative to the official native Android and iOS apps. According to Twitter, Twitter Lite consumed only 1-3% of the size of the native apps. In July 2019 Twitter started serving all website users to Twitter Lite by default. On June 1, 2020, Twitter deactivated the legacy website layout, leaving the progressive web app version as the only option.
Starbucks provides a PWA that is 99.84% smaller than its equivalent iOS app. After deploying its PWA, Starbucks doubled the number of online orders, with desktop users ordering at about the same rate as mobile app users.
Several businesses highlight significant improvements in a wide variety of key performance indicators after PWA implementation, like increased time spent on page, conversions, or revenue.
As I take many screenshots, I was relieved to discover the following keyboard shortcuts:
- Take a screenshot: Press Ctrl + Show windows
- Take a partial screenshot: Press Shift + Ctrl + Show windows , then click and drag.
Another issue is that my poor quality webcam does not work which is unfortunate but it's something that I never use so it's no great loss to me. Obviously, it could be a deal breaker for some who need to use the device on a regular basis.
Additionally, my Express VPN does not support Chrome OS which seems odd but I'll investigate the matter further and will consult with the company's technical support if I can't resolve the issue.
Overall I'm happy with my new operating system that is still in unstable beta release. I'll look forward to some of my existing problems disappearing during future updates to the operating system.

Resuscitating Old Laptops
An acquaintance asked me some time ago to resuscitate an old laptop that had ceased to function. It had been running Windows. The laptop, an Asus X401U, dates back to about 2012 when it was being sold for US$280 as a cheap netbook. It has a Celeron processor running at 1GHz with 2GB of RAM and a 320GB hard drive. The graphics are integrated Radeon and eat into the already meagre memory. Most versions of this laptop came with 4GB of RAM but not this particular model. See Figure 1.

Raspberry Pi
Unfortunately, Minecraft and Wolfram Mathematica are missing because the licensing agreement only applies to the OS running on a physical Raspberry Pi. No matter, it's still good to be able to experience and work with the software in a virtual environment.
PIXEL represents our best guess as to what the majority of users are looking for in a desktop environment: a clean, modern user interface; a curated suite of productivity software and programming tools, both free and proprietary; and the Chromium web browser with useful plugins, including Adobe Flash, preinstalled. And all of this is built on top of Debian, providing instant access to thousands of free applications.
