Apple migration/software update discussion traces a bizarre update loop back to a BOM bug, describes a bad Time Machine migration fixed by migrating from a clone, and discusses issues involved in migrating from an old iMac to Catalina.

macOS Catalina notes touch on virtualization, sleep bugs, 32-bit software elimination, forced update fiascos, a vexing file-open problem, and more.

MacInTouch Community updates also include the following topics (among others):

Anker USB-C Ethernet adapter

Anker USB C to Ethernet Adapter [Amazon] provides a Gigabit Ethernet (10/100/1000 Mbps) connection for Macs, Windows and Linux computers with USB ports but which may lack Ethernet ports of their own. The device’s  built-in USB-C cable plugs into a host computer USB-C port or you can use it with standard USB 3.0 Type A ports via an inexpensive adapter (e.g Onvian USB C to USB 3.0 adapter). Other features include a compact enclosure with aluminum or space gray exterior and three helpful status indicator lights.

Anker USB C to Ethernet Adapter has a list price of $19.99 but is typically discounted at Amazon. Onvian USB C to USB 3.0 adapters were priced at $4.99 for two, when checked.


BBEdit is a professional HTML and text editor from Bare Bones Software Inc., aimed at web and software developers. Features include pattern matching (“grep”); search and replace across multiple files; the ability to edit columns (in “delimited (CSV, TSV) text files”); function navigation and syntax coloring for numerous source code languages; code folding; text and code completion; FTP and SFTP open and save; AppleScript support and a “text factory”; Unix scripting support and a complete set of HTML markup and clean-up tools.

Version 13 was a major update, first released last fall, that includes “Pattern Playgrounds … for learning, developing and testing regular expression search patterns (‘grep patterns’) in a safe environment” and “live display of both literal and regular expression matching while entering a search string in the Find window”, plus an “Apply Transform command, which provides a powerful, immediate means to apply any single text transformation to multiple files and folders”, among many other improvements.

BBEdit 13.0.3 is priced at $49.99 for macOS 10.14 and later. The BBEdit download runs for 30 days with all features enabled for evaluation and then continues with a reduced feature set free of charge. (The free BBEdit mode replaces BBEdit’s earlier TextWrangler app.)

MacVim is an enhanced version from Björn Winckler and others of the widely used text editor with its old Unix user interface that predates modern, graphical Macintosh “apps.” In fact, Vim is included in the macOS Unix command-line libraries accessible via Terminal, and MacVim may best serve as a training ground for learning Unix-style editing.

MacInTouch Community updates also touch on the following topics (among others):


BusKill is a simple system/method from Michael Altfield for protecting your data from laptop thefts, etc.

Let’s consider a scenario: You’re at a public location (let’s say a cafe) while necessarily authenticated into some super important service (let’s say online banking). But what if–after you’ve carefully authenticated–someone snatch-and-runs with your laptop? Maybe you can call your bank to freeze your accounts before they’ve done significant financial harm. Maybe you can’t. Or maybe your laptop was connected to your work VPN. In less than 60 seconds and with the help of a rubber ducky, the thief could literally cause millions of dollars in damages to your organization. Surely there must be some solution to trigger your computer to lock, shutdown, or self-destruct when it’s physically separated from you! There is: I call it BusKill. Surprisingly, I couldn’t find a low-tech solution that implements a laptop kill cord, so I decided to build one myself for ~$20 and a simple udev rule.

Satechi Backlit Bluetooth Keyboard

Satechi’s Compact Backlit Bluetooth Keyboard offers a somewhat rare combination of features: Mac-style keyboard layout, backlighting, compact size with numeric keypad, rechargeable battery, USB-C charging port, and Bluetooth 5.0 wireless connectivity with the ability to switch instantly among three different host devices.

SpyderPrint is a product from Datacolor for creating print calibration profiles with the help of a spectrocolorimeter and cross-platform software. The process involves printing “targets” on your particular printer and paper then using the spectrocolorimeter to scan the printed patches to build an ICC color profile that you add to your system in order to accurately predict and optimize results with that printer/ink/paper combination, from editing and soft-proofing to final output (assuming your display is also calibrated). Other features include a SpyderProof function with “carefully selected” sample images and a variety of controls and options. (See Users Guide [PDF] for more details.)

SpyderPrint (S4SR100) lists for $349 ($344 at Amazon when checked) for OS X 10.7 through macOS 10.12 or Windows. SpyderX Pro is a monitor calibration system from the same company (but you can use a different monitor calibration system instead, if you choose).
