Michael Tsai - Blog - How Kernel Prelinking Works on macOS Catalina (or Not)
(On updating kernel extensions being broken (as of 10.15.0))

“‘When you reboot or shut down your machine, launchd stops all processes. Then it remounts the system volume in read/write mode. This is possible because launchd has the entitlement Then it runs /var/install/shove_kernels to copy the new kernel.’

“But apparently this doesn’t actually work. So to update a kernel extension you need to disable System Integrity Protection or manually trigger a kernel update after booting into macOS Recovery.”

Michael Tsai - Blog - iTunes XML and Music in Catalina
(On iTunes breaking access through its XML file:)

“According to Apple, the new Music app, which replaces iTunes, removes support for automatically syncing playlists with third-party apps using XML. XML file support is a popular organizational feature for DJs who use it to sort tracks into playlists and utilize the “Share iTunes Library XML with other applications” option to seamlessly transmit data between apps.”


“A statement from Apple initially said XML would not be supported within the app. This story has also been updated to clarify that Music supports a new method for automatically syncing playlists that third-party apps can be updated to support.”


“In the macOS Catalina Music app, you can no longer have this file created automatically, but you can create it manually.


“To do this, choose File > Library > Export Library, name the file, and save it.”

Michael Tsai - Blog - How to Flip an App for Profit
“Background used to be a good app. You can tell from its early reviews that its users genuinely enjoyed browsing and making use of its hand-curated selection of iPhone wallpapers. In fact, its reviews are generally positive up until late June, when an update began causing some issues. From that point on it becomes clear that Background is no longer owned or updated by its original developer. It’s been flipped.


“The gold standard seems to be a 3-day trial that moves into a $9.99/week subscription, but there’s flexibility here, depending on precisely how evil you want to be. Make sure to hide these new payment options from your pre-acquisition users. After all, you don’t want them updating their glowing past reviews. Oh, and for those new users you’re about to acquire? Make sure it’s darn near impossible for them to find the ‘x’ to close your subscription view (or, for fun, make it completely nonfunctional!).”

Michael Tsai - Blog - Per-Build Release Notes
“Most Mac websites only report that Apple released a new Beta, but don’t mention any of the actual changes. This article is meant to save you time going through the notes to find what is new and what is still leftover from the last beta. I went through both Beta 6 and the new 10.15 Beta 7 (19A546d) release notes to find all the changes. Like usual, I also have included the entire patch notes list as an archive.”

Michael Tsai - Blog - Mojave Finder’s Preview Column Shouldn’t Prioritize Thumbnail Size
“Mojave puts a lot of information at your fingertips in Finder windows. However, the priority given to different components isn’t currently right. In particular, too much vertical space is reserved for QuickLook thumbnails (icons).

“Even in a very deep Finder window in Column mode, a shallow QuickLook thumbnail is given so much space that you have to scroll in order to be able to see that file’s metadata and the Quick Actions bar below it. This is in a Finder window on a 5K display at ‘looks like 2880 x 1620’ mode: it gets much worse on a laptop.”

And then one of the commenters replied with this tip:

“Try selecting a file type in the Finder and choosing ‘Show Preview Options’ from the View menu. It has checkboxes to show/hide filetype-specific metadata as well as the Quick Actions.”

Michael Tsai - Blog - on macOS 10.15
On Catalina’s new Music app to replace iTunes:
“As I dig deeper, I find that a lot has been simplified. There are tasks I had described in my book that had multiple steps that are simpler, and there were often several ways to do something, whereas, now, there is generally just one. I find myself cutting large sections of my book’s content because of this simplification.

“I will miss the column browser; I used this tool constantly to navigate my library by Genre, then Artist, then Album. With Artist, Album, and Genres view, it’s hard to get the big picture. If you have, say, 135 Grateful Dead albums, you need to scroll through the Grateful Dead entry to find the one you want, whereas in the column browser, I could quickly scan a concise list. Or when I wanted to listen to Kind of Blue, it took a few clicks, a quick scan, and I found the album.

“The other feature I’ll miss is that in Songs view – that’s the one where you see items in a list – you can no longer display album artwork. I used that extensively, together with the column browser, as you can see above, because it’s a quick way to scan content to find what I want.”

Michael Tsai - Blog - Sidecar
“The core experience of using Sidecar is fantastic. Part of the reason is that running an iPad as a second display for a Mac with Sidecar is immediately familiar to anyone who has ever used multiple displays. The added screen real estate, portability, and functionality are part of the appeal too. Of course, there are differences that I’ll get into, but Sidecar is so close to a traditional dual-display setup that I expect it will become a natural extension of the way many people work on the Mac.”

Michael Tsai - Blog - Amazon Has Ceded Control of Its Site
“In practice, Amazon has increasingly evolved like a flea market. It exercises limited oversight over items listed by millions of third-party sellers, many of them anonymous, many in China, some offering scant information.

“A Wall Street Journal investigation found 4,152 items for sale on Inc.’s site that have been declared unsafe by federal agencies, are deceptively labeled or are banned by federal regulators—items that big-box retailers’ policies would bar from their shelves. Among those items, at least 2,000 listings for toys and medications lacked warnings about health risks to children.”

Michael Tsai - Blog - The Fate of the iTunes Store in macOS Catalina
“In early betas of macOS Catalina, the iTunes Store was visible, but in recent betas it did not show up in the sidebar of the Music app if the user was signed into Apple Music. That seems to be the default now: if a user has an Apple Music account, they won’t see the iTunes Store. You can display it, if you wish, in the Music app’s Preferences, on the General pane, but if you’re a streamer, you won’t see it by default.

“You’ll note that in the screenshots on Apple’s macOS Catalina preview pages, the iTunes Store is not visible.”

Michael Tsai - Blog - Lowercase Passwords
“Your master password should be at least 12 lowercase characters or five words. Why use lowercase characters or words when you’ve probably been told (and coerced) to use uppercase characters and symbols in the past? If you have to enter the password on a device with on on-screen keyboard (like your phone’s), each uppercase letter or symbol may require extra key presses. You can get the same security, and save yourself a great deal of frustration, by making your all-lowercase password just 30% longer than if it were mixed case. In other words, a randomly-generated 13-character lowercase password, which can be entered with 13 keystrokes, is as secure as a 10-character mixed password, which may require many more.”

Michael Tsai - Blog - MacUpdater 1.4.15
(Well, this looks pretty neat.)
“I have only really tried MacUpdater, and it’s become one of my essential tools to have on the Mac. I have only had a quick look Latest, and it only covers app that use the Sparkle framework plus apps that are from the Mac App Store. Sure, those are already a lot of apps covered, and it’s free, but with the license for MacUpdater you get support for apps distributed via Sparkle, MAS, Homebrew Cask, individual developer appcasts, releases via GitHub etc., and CoreCode also maintain their own database of apps, which includes apps that users have installed/updated manually… even some of my own Platypus apps have found their way into the CoreCode database. And last, but not least, you can ask CoreCode to add apps to their database, if they’ve missed some special/obscure software.”

“Whether your pump advertises it or not, however, there’s a handy way to shut the dang thing up. There’s an array of buttons along the side of the screen.

To figure out which one, just start at the top and start pressing each button until you find the one that gives you the blissful silence you’re looking for.”

Michael Tsai - Blog - ScanSnap 64-bit Software Update
From one of the comments is this tidbit about VueScan, that alternative scanning software for older ScanSnap scanners:

“Try taking a look at VueScan. They do have drivers for Fujitsu drivers, including the ScanSnap S500

“I used VueScan with my PlusTekOpticFilm Film scanner to scan several hundred of my Dad’s old slides (plus a couple of my own color negatives) and was very satisfied with the results. I felt it was better than the software that was packaged with the scanner.

“I wrote about it a couple of times on my blog; the first entry is here:”

(And there’s also this comment:)
“Ditto that. The first time I used VueScan years ago (when someone passive-aggressively gifted me a scanner that only had Windows drivers – and VueScan worked), I stopped worrying about how good a scanner’s Mac drivers were. If VueScan supports it, you’re in business. It’s almost worth the price to save you the time trying to learn how to get first-party drivers to work.”

(And this comment too:)
“I agree with @Ted and @Ruffin. I only buy scanners supported by Vuescan. You sometimes still need a basic driver from the manufacturer so it’s not full proof, but the crap software bundled is no longer a concern.”

(And then there’s this comment that vouches for ExactScan:)
“I use ExactScan, which still supports these older scanners, as well as Fujitsu scanners which have never been supported on the Mac (I have an fi- 6140) as well as hundreds of scanners from other manufacturers.

“It supports all of the high-end features of these scanners, like duplexing, media detection, blank page detection, automatic OCR, and imprinting. You can also build out custom workflows and configurations (email, copy, PDF, etc.) It’s very well supported and one of the best pieces of software I’ve ever purchased. It breathed new life into this 9-year old, $1400 scanner.”

They are Mimeo Photos and Motif. (Unsurprisingly, the companies behind both apps seem to have been past suppliers for Apple’s book-printing services… so this is their way of staying in the game.)”

Michael Tsai - Blog - Apple Event Sandboxing in macOS Mojave Lacks Essential APIs
“I ran into another usability challenge that Felix didn’t itemize: the problem of denying authorization to an application and then living to regret it. I guess at some point I must have hastily denied permission for Xcode (Apple’s software development app) to control the Finder. This resulted in a seemingly permanent impairment to Xcode’s ‘Show in Finder’ feature. I’m often using this feature to quickly navigate from Xcode’s interface to the Finder’s view on the same files. After denying access once, the feature has the unfortunate behavior of succeeding in activating the Finder (I guess that one is whitelisted), but failing silently when it comes to revealing the file.

“OK, that’s fine. I messed up. But how do I undo it? Unfortunately, the list of applications in the Security and Privacy preference pane is only of those that I have clicked ‘OK’ for. There’s no list of the ones that I’ve denied, and no apparent option to drag in or add applications explicitly. For this high level problem, I filed Radar #42081464: ‘TCC needs user-facing mechanism for allowing previously denied privileges.’”

One thing I found that helps is to take my iPhone and try to share something (I usually use a web page) via AirDrop with the Mac.

Michael Tsai - Blog - You Are Probably Using the Wrong HDMI Cord
“There may be 13 different HDMI standards (see also, but there are only four HDMI cable types: standard (4.95 Gbit/s), high-speed (10.2 Gbit/s), premium (18 Gbit/s) and ultra (48 Gbit/s). The differences are entirely a matter of how much bandwidth they can reliably deliver and have nothing at all to do with HDMI version numbers.

“This is because every HDMI version defines a large collection of features. Some features require more bandwidth than others. If you have a new "HDMI 2.1" device but it is only using those features that require 10.2 Gbit/s or less, then you don't need an "ultra" cable. The only people who will require that are those using high-end HDMI 2.1 features (like 8K video) that are not supported by any consumer devices at this time.”

Michael Tsai - Blog - Faster Swiping Between Pages
“One of the irritations is that, if you’re using a trackpad, it reloads the page each time you two-finger swipe to go back. This can be slow but also infuriating if you’re scrolling through an auto-updating webpage list, for example, because the page will reload and you’ll be thrown back to the top of the list.

“The solution is to activate three-finger back gesture—and then train yourself to make use of it. Here’s why: For reasons only known to Apple software engineers, using this gesture instead of the standard two-finger swipe means the page isn’t reloaded. It’s looks just as it did when you clicked away from it and it instantly appears without any redrawing or rendering.”

Michael Tsai - Blog - External MacBook Pro Displays
(Hmm—this thing is actually kinda tempting.)
"I wanted a larger, portable external display for my MacBook Pro, so a few months ago I got an AOC e1759Fwu. It’s a 17-inch display with a fold-out stand that easily fits in my laptop backpack. It connects via a USB cable (no separate power connector) and, once you install the kernel extension, the Mac sees it as a regular external display (though Night Shift is not supported). It supports both portrait and landscape modes. I prefer the portrait, which at 900 × 1,600 pixels (it’s not Retina) is the same height as a 30-inch display.”

"The AOC’s USB 3 connection is a big improvement over the square-SCSI SuperMac adapter that I once used to connect a color display to my monochrome PowerBook, but it does feel laggy compared with a regular display connector. The picture quality isn’t great, either: a bit fuzzy, uneven brightness, and so-so color."

Michael Tsai - Blog - Hiya: Filter Spam Calls
"Out of desperation, I’ve tried a few of these Apps claiming to screen or block suspected spam callers as they’ve popped up in the App store. Thus far the only one I’ve found that has worked somewhat reliably is Hiya. (Glenn Fleishman writing for Macworld has a more extensive review)


"One concern of note, Hiya requires users to provide access to their contacts, a request that always makes me leery. Hiya told Macworld the data is required to add contacts to its whitelist and the information is kept private. Still, be aware. After a few months of use I’ve found Hiya overall accurate with a few bugs that have been fixed by uninstalling and reinstalling the app."
