Updated and republished for macOS 11.5.2; skip it unless you really really care about all the macOS releases. Originally published on November 14th, 2005.
Below the break is a table showing all major releases of macOS (previously Mac OS X) from the public beta through the latest public version, which is 11.5.2, as of August 11th, 2021—the 153rd release in total.

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.
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.
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.)
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.
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…
This thing was surprisingly inexpensive, at only $27 (on sale for $20 when she bought it). I let it sit for a couple weeks, then decided to put it togther—how bad could it be, I figured, with a target age of eight years old? And only four to six hours to assemble? (That's not just Costco's estimate, it's on the back of the box, too.)
As it turns out, it could be bad, really bad. It was still a fun project, but both "four to six hours" and "eight years old is fine" are complete fabrications.
I recently received my Apple M1-powered 13" MacBook Pro, which is primarily going to be used for testing our apps on Apple silicon, and supporting customers using these machines. But that doesn't mean this is a work machine; it's a personal purchase as I'll use it for my own needs as well. (Thankfully, it only had a net cost of $33 after I sold my 16" MacBook Pro.)
By now, you've probably read a slew of stuff about both the MacBook Pro and its slightly-lighter MacBook Air cousin. Between unboxing videos, extensive benchmark suites, and multi-thousand-word reviews, there is no lack of coverage of these machines. (However, I will add that I did make a video of my MacBook Pro—with its 16GB of RAM—opening 75 apps in just over a minute. Not bad for an entry-level machine!)
I'm not going to try to replicate those reviews, because they do an excellent job of covering the new M1-powered Macs in a level of detail that I just don't have time to get into. Instead, here's what I'll be discussing…
I ordered my 13" M1 MacBook Pro with 16GB of RAM, as I felt buying the most offered was the best bet for future proofing this "entry level" M1 chipped Mac. Later today I'll be posting a detailed writeup of my time so far with the new machine, but for now, here's a little over-the-top demo.
I selected everything in the Applications folder—excluding Time Machine, Siri, Launchpad and a few other similar non-apps—and opened them all at once. I did this with a timer running, while recording the screen, and here's the result…
As you can see at the end of the video, it took one minute and seventeen seconds to open all 75 apps—do the math, and you'll see that's about 1.5 seconds per app (it was notably quicker than that at first, and slower than that at the end). For 75 apps. On a machine with nowhere near enough RAM to fit them all in active memory. I was amazed at how rapidly it was able to complete this task.
These weren't even all native apps, it was a mix of Intel, Apple, and Electron (both native and non-native) apps.
I tried a similar test on my MacBook Air, but as it's an 8GB RAM machine, I limited it to opening 37 apps, which took it well over three minutes (about 5.5 seconds per app). I didn't bother to try on my iMac—it has 40GB of RAM, but it's also got a slower SSD, so I don't know that it would've matched the MacBook Pro's performance.
I've been having an odd issue with the Mac App Store app on my Mojave-running iMac: Sometimes the App Store app will fail to install an update for some app. When that happens, I see a dialog with this text as the title:
We could not complete your purchase.
Below that is a single word, "cancelled," and that's all. Searching the web, I came across this thread on stackexchange.
What finally worked for me was a combination of things listed there—none of these steps on their own seem to fix the problem, but all together do, at least until it occurs again.
Quit the App Store app.
Switch my DNS to another provider.
In Terminal, paste this command and press Return: open "$TMPDIR/../C/com.apple.appstore/"
Confirm that the Finder opened a window to the com.apple.appstore folder, then drag everything there to the trash.
Back in Terminal, paste this line and press Return: killall -9 appstoreagent
Relaunch the App Store app.
This method has worked for me each time I've had this issue. It's annoying that it keeps recurring, but at least the fix is relatively simple.
