Create a macOS Catalina Bootable Drive for Installation
Roman Loyola shares a tip for Apple users looking to upgrade: Creating a macOS Catalina bootable drive.
An external drive that you can use as an installer for macOS Catalina is a handy thing to have. If you have multple Macs to upgrade, it’s a lot more efficient to plug in the USB installer drive and run the installer than to log into the App Store, download the 6.5GB OS installer, and then run it.

32BitAppCheck Helps You Transition to macOS Catalina
32BitAppCheck is an app that scans for 32-bit apps on your Mac. It can help you prepare for macOS Catalina because this release will end support for 32-bit apps. It takes about 30 seconds to scan your computer (longer if you have hard drives plugged in). Once it’s finished it will present a list of all the 32-bit apps it found, which you can save as an .RTF file.
Information then collected in the app’s window begins with a list of 32-bit applications, followed by 32-bit preference panes found in System preferences. Then, you will see 32-bit system extensions, and 32-bit system frameworks. These software will include both Apple and 3rd-party software. You can then edit the information, changing fonts, and adding notes. Click Save to save the information in an RTF file. The most recent information with you edits is also saved within the app.
You can download the app here. As this is an app outside of the Mac App Store, I scanned it for malware using VirusTotal, and it appears to be clean. For an additional resource I’ve also written about Go64, which does the same thing and the UI is a bit more friendly.

The Origins of Unix - Now 50 Years Old
ars technica has posted at terrific story by Richard Jensen on the origins of the Unix operating system back in the late 1960s.
Maybe its pervasiveness has long obscured its origins. But Unix, the operating system that in one derivative or another powers nearly all smartphones sold worldwide, was born 50 years ago from the failure of an ambitious project that involved titans like Bell Labs, GE, and MIT.
A derivative of the original Unix OS, in the family tree of BSD, is the basis for macOS, iOS, and is even running in your Apple Watch.
Rumors Still Live for Apple's Bluetooth Tile Competitor

All About Apps Phoning Home. And Firewalls
The Eclectic Light Company writes:
A few years ago, most Mac users had firewalls in their routers which blocked all incoming connections, and that was all they wanted. Over those years, we’ve increasingly installed software firewalls on our Macs to block outgoing connections. This article looks at some of the issues that arise from doing that.
The rules of the game keep changing, and this article brings us up-to-date.

About the macOS Transparency Consent and Control System
The Eclectic Light Company writes:
The Transparency Consent and Control (TCC) system [in macOS] maintains a database of each user’s consents.
This article explains what you must do when uninstalling software in Mojave, and presumably Catalina, in order to remove previous consents for access to protected resources.
If you were to reinstall that software, you would see that it was immediately granted the same access as when it was removed, without your consent being sought again.
This is an interesting and informative article about the seldom discussed macOS TCC.
