VMware Fusion and the vmmon broken pipe error

As part of my struggles to fix my constantly-crashing suggestd process (and the Spotlight failures that it seems to cause), I reinstalled macOS Mojave a couple of times using the Internet Recovery partition. These were in-place reinstalls, so I didn't start completely clean, but the OS is reinstalled from scratch—so much so that I even had to run the 10.14.6 updater and a couple of security updates again.

In the end, not only did this not fix the suggestd problem, but it also broke my all-important VMware Fusion virtual machines. When I tried to launch any of them, I was greeted with an error message:

Error: Could not open /dev/vmmon: Broken pipe

This is apparently so common that VMware has a knowledge base article on the issue. The error is due to VMware Fusion not loading its required kernel extensions, but nobody seems to be sure of the cause of the problem. However, that article is supposed to fix it…unfortunately for me, it did not. I never saw an entry in the Security & Privacy System Preferences panel to allow VMWare's extensions. As a result, they didn't load.

Here's the tl;dr for the fix that did work: Rebooting in Recovery mode (hold down Command-R at startup) and deleting the KernelExtensionManagement folder located in /private/var/db. There was a lot more to it than that, though, which I cover for my own possible future needs in the rest of this post, in case the linked sources ever vanish.

My iPhone 13 Pro and its ultra-short battery life

Yesterday on Twitter, I bemoaned my new iPhone 13 Pro's surprisingly short battery life:

I've been seeing very short battery life on my iPhone 13 Pro—it barely makes it from 5am to 8pm despite it just sitting here on the desk most of the day.

Battery usage shows a sustained constant drain—and neither Music nor App Store were even running today.

WTF?

You can see full tweet thread with follow-ups, but here's the key graphic:

Each day, the battery would drain smoothly and continuously—you can see the pattern repeating on the prior day, as the battery dropped to under 20% by 9:00pm. This was happening despite the fact that I work at home and rarely use the phone while here—I might look at Twitter occasionally or launch an app or two, but it mostly just sits on my desk.

As Apple touts up to 22 hours of video playback for the iPhone 13 Pro, I didn't think it should be draining to under 20% in about 12 to 15 hours of non-usage. So the debugging started.

If you want the tl;dr, here it is: I turned off wifi sync, and the problem seems to have vanished. Read on for the details and a before-and-after comparison image.

A mini review of a mini arcade cabinet game

Being a person of a certain vintage, I have a soft spot in my heart for the arcade video games of the 1980s—Asteroids, Pac-Man, Missile Command, etc. I've long wanted to get an original game in its full-sized cabinet, but they're large, increasingly expensive, and complicated to maintain.

So I use MAME to run such games on my Mac, but it's just not the same as a physical machine. I've considered building my own cabinet, but then remembered that I have essentially no carpentry skills (or tools!). Enter Arcade1Up, who offer smaller (yet still substantial) cabinets with fully licensed versions of many classic arcade games.

After watching for sales for a while, I saw a deal on the BANDAI NAMCO Entertainment Legacy Edition Arcade Machine (wow, what a name). This cabinet includes 12 games, though only three—Pac-Man, Galaxian, and Galaga—were of much interest to me. The kit also included the riser, making it playable while standing up.

The kit retails for $449, but I caught it on sale at Walmart (via slickdeals, a site that either saves or costs you a small fortune, depending on how you view it) for under $300. I wasn't quite sure what the quality of the kit would be, as even at $449, it seems relatively inexpensive.

I had the kit sitting here for a bit before I had time to put it together, but now, as you can see by the image at right, it's done. If anyone else is in the market for one of these, I thought I'd share my thoughts on the kit and using the finished product.

Remove tracking data from copied URLs

A while back, my friend James and I were discussing the amount of tracking cruft in many URLs. In my case, I subscribe to a ton of email newsletters, and I noticed that those URLs are just laden with tracking information—and most go through a URL processor, so you don't really see those tracking details until you've clicked the link, at which point it's too late to avoid any tracking.

I wanted a way to clean up these URLs such that the least-possible tracking information was sent to a server—and in particular, to prevent any browser cookie creation. In addition, if I want to share a link with friends, I don't want to send them a crufty tracker-laden link—I wanted a nice clean shareable URL.

Note: I wrote all of this before I knew about Jeff Johnson's Link Unshortener, which does all of this (and more) in a "real" app. If you'd like the easy solution, Jeff's app is the way to go. Mine is definitely a do-it-yourself concoction that's not for the faint of heart.

tl;dr version: Install this macro group (v8.1) in Keyboard Maestro to remove tracking details from copied URLs in a set of defined apps.

Latest Update: Dec 5 2021 I made a fundamental change in when copied links are opened in the browser—they now only open if you hold the Option key down while copying the link. I also made some changes that should make future updates easier for those who customize this macro. Please see the release notes section for more details about these changes, as well as notes on prior updates.

See the update notes section for details on how to update the macro if you've already installed a prior version.

The Impossible Move™

A while back, I lamented on Twitter about the non-functional Apple Configurator 2, which had been my preferred way of organizing apps and folders on my iOS devices:

As an example of why it's so incredibly frustrating to try to do this on an iOS device1I've confirmed the issue on both iOS and iPadOS., I offer you The Impossible Move™, otherwise known as TIM (sorry to all the Tims out there). The steps to demonstrate TIM are trivial:

  1. Create a screen full of apps and folders, such that there's no remaining space.
  2. Position a folder in the rightmost lower corner of the screen.
  3. Attempt to drag an app from another screen into that folder.

Off to the right, you can see just how impossible TIM is: Completely impossible.

When you first drag the icon over to the target screen, you can watch the target folder literally disappear. Where'd it go? Perhaps it went back to the screen you came from…but if it did, as soon as you drag back to that screen, the folder returns to its original location.

Argh!

I know of only two solutions to this problem. One, of course, is to not completely fill the screen, which is my general approach. (I created this screen layout just for the purpose of the demo video.)

But that's not always possible, at least on my phone: On the first screen (the "home home screen?"), I have a large full-width widget. The presence of that widget seems to require the screen to be 100% full of icons in its remaining space—if I drag one off, then some other one is randomly placed in its spot, insuring the screen stays full. (Even worse, the widget gets relocated to the middle of the screen, with icons above and below.)

The only solution I've found that works for all cases is this one:

  1. Move the target folder to another location on the screen.
  2. Move the target app into the target folder.
  3. Move the target folder back to its original location.

To reiterate my earlier tweet…please, Apple, provide an official solution for home screen management using a Mac. The larger screen and ability to select multiple items using the mouse makes short work of organizing an ever-growing collection of apps and folders. On-device organizing is nothing but an exercise in frustration.

Archiving and version control for Keyboard Maestro

As much as I rely on our own Many Tricks' apps every day, there's one I rely on more: Keyboard Maestro (KM), the macro app for macOS that can do pretty much anything. How much do I rely on it? The shrunken image at right lists all of my macro groups—not macros, just the groups holding the macros. In terms of actual macros, there are over 425 at present. (These are not all user-facing; many are macros that support other macros.)

I use KM for everything from gathering monthly utility bills to inserting HTML code in blog posts to generating replacement license files for users to controlling iTunes to decrufting URLs when copying (future post coming on that one) to automatically naming and filing documents I scan to storing snippets for insertion into our apps' help files to opening oft-used URLs to adding key functionality to many apps such as Excel, Mail, Messages, Photos, Preview, Safari, etc. In short, it's the single most-used app on any of my Macs.

For as much as I love KM, it has one major shortcoming: All of those macros live in one large XML file. Yes, I back it up to many local and cloud locations, so I'm not worried about losing it. It does mean, though, that if I mangle a single macro while trying to fix something, there's no easy way to get back to the working version (assuming I've gone past the point of multiple undo steps).

But now I can recover from such stupidity, thanks to the amazing Macro Repository Suite from Dan Thomas. This suite consists of two macros: One that updates (and initially creates) the repository, and one that restores a given macro from the repository.

We have (semi) new robotic vacuum overlords

In late 2019, I wrote about how we were using two Deebot robotic vacuums to help keep our floors clean. And while these vacuums worked well, they had two issues that became more annoying as time passed:

  • They clean using a random path method
  • There's no way to map out obstacles they should avoid

The Deebots are basically non-intelligent robot vacuums. They have the ability to avoid bumping into things, and they won't fall off drop-offs, but that's about where their intelligence ends. They clean using a random path, which works but seems very inefficient. Much worse, though, is that there's no ability to mark areas you don't want them to clean.

For me, that meant I had to close the door to our laundry room so it wouldn't try to clean and get stuck in there. And block off access paths to other areas where it could get stuck. And put one shelf on risers, as the Deebot seemed to be able to get under it, but not back out!? And I had to do this any time I wanted to run the vacuums. That gets old pretty quick.

I wanted to find a vacuum that would clean in a more orderly fashion (using some sort of room map), and to electronically block off areas where they shouldn't clean. The problem was most vacuums that offered these features were (at the time) $350 or more, while the Deebots had cost us only $170 or so. So I kept searching and waiting.

tl;dr version: We bought two Wyze Vacuums with LIDAR and restricted area capabilities, and love them. Ours cost $225 each, but the price today is $267 each. Read on for a much more detailed review, if you wish.

Remember, kids, RAID is not a backup!

Major update: The QNAP box failed tonight (Aug 3) after running flawlessly for three days straight. I went out to grab some dinner (I shouldn't leave, ever, apparently), and came back to the RAID offline with just a power light, no USB or drive lights.

I moved the drive from a USB hub on a long cable to directly into my Mac on a short cable. Same problem. I then pulled the drives from the array and dropped each into my drive dock, and they were both fine. (All my data was gone, though—thankfully I had literally cloned the drive just before I went out.)

Needless to say, the QNAP box is going back. I've ordered a different unit, with a different chipset in it, but it won't be here for about a week. In the interim, I've put my new drives in external enclosures, and I'll just use Carbon Copy Cloner to mirror them every 30 minutes or so. I've edited the post to reflect my experience.

I'll edit and repost this once the new box is here and (hopefully) working, though I might wait more than three days after it arrives, just to be sure!

On my iMac, I have a fair amount of data—somewhere around eight terabytes or so spread across 15TB of drive space. Until last week, I had it split between the internal SSD (work and personal files I access a lot), an external 6TB USB drive (archive stuff I want to keep but not regularly access), and an external 8TB RAID box (a whole bunch of music, movies, home videos, work videos, etc.)

Being paranoid, I also had relatively good—but not bulletproof, as I discovered–backup strategies for all of these things. And it's a good thing I did, as last week, my external RAID box died in spectacular fashion. While I was out of town, no less. And that's why they say, "RAID is not a backup!"1Many RAID levels duplicate your data, but if something happens to the RAID box itself, the data is toast.

So what happened, how'd I recover, and what's my new plan going forward?

Avoid a text selection bug in Excel

I like Excel. I cover it often here, and I use it in projects where it probably would make more sense not do to so. Like my current task, which is developing a stats tracking package for a billiards training game (yea, obscure, I know).

While working on this workbook, I ran into a problem where I couldn't effectively select text in the formula bar: Whenever I tried, the selection would continually grow back to the left, regardless of what I did with the mouse. I also couldn't click on a location in the formula to place the cursor there; it would instantly start selecting text. It looks like this:

But this didn't always happen—in fact, it didn't happen very often at all. And I didn't seem to see the problem in new workbooks, only this one, and then sometimes seemingly randomly, in others. After way too much troubleshooting, I figured out the cause and the solution:

If you resize the pop-up menu at the left of the screen, that triggers the selection bug. Resizing after that, even back to where it was, won't help. You can either close and reopen the workbook, or drag the slider to remove the box. This video shows the entire process, from working to broken and back again:

I don't know how old this glitch is—it exists at least as far back as Excel 16.33 (16.46 is current). I'm trying to get someone at Microsoft's attention, but if you can help, please do—it's a very annoying bug.

A problem of time with Big Sur screencasts

As part of my job, I occasionally have to make screencasts, usually demonstrating features in our various apps. Sometimes I need to record the entire screen, as I'll be demonstrating things that require activating and selecting menu items. I have a demo account I use for these recordings that lacks all of my usual menu bar add-ons, so the look is quite clean.

And in versions of macOS prior to Big Sur, I also hid the menu bar clock (via System Preferences → Date & Time → Clock, uncheck "Show date and time in menu bar.") But in Big Sur, the menu bar clock is also the button you click to open Notification Center…so there's no way to remove the clock from the menu bar.

Most of the time, this isn't a problem. But when recording screencasts, it's a big issue. I often record segments across days, and at multiple times a day. I then splice those bits together, often times not in a linear fashion. With the default Big Sur settings (displaying the full date and time), this leads to a real annoying time travel experience as the clock jumps around like crazy.

The following two tips help greatly with this problem, though being able to hide the clock entirely would be a much better solution…
