Mac OS X Hints

Zoom zoom zoom

Today's tip is simple, yet for me, critical—it's one of the first things I do when I set up a new Mac or user on an existing Mac, as it solves a vexing issue: Small fonts that can't be modified within an app's preferences. As my eyes get older, these small fonts get more and more annoying.

Thankfully, there's a fix in the Accessibility section of System Preferences, specifically on the Zoom tab: Easily zoom the screen via keyboard or gesture shortcut. Here's the setup screen:

You can choose to use keyboard shortcuts to zoom (top section of the full screenshot), or (my preference) a scroll gesture with a modifier key. There are also some useful options in the "Zoom style" section.

Microsoft’s public-by-default file sharing site

This morning on Twitter, I saw that @rosyna had retweeted this tweet from @GossiTheDog:

https://twitter.com/gossithedog/status/845446263244050434

That seemed insanely scary, so I did a quick search on docs.com for password 1I am not revealing anything secret here; the original tweet went to thousands of people, and many have already noted the number of shared password files.. The results were quite shocking—hundreds of files containing full login information to major sites—Apple, AT&T, Facebook, Gmail, Linkedin, Netflix, PayPal, Twitter, etc.

It seems crazy to think that these users are intentionally sharing this information with the world. I wanted to see how it was happening, so I logged into docs.com with my Office365 account to see. I created a simple file to upload as a test. After uploading, you have to set a bunch of options before you save the file; one of the settings is the Visibility, and this is the default setting:

Yes, docs.com defaults any uploaded file to world-visible, "giving it a larger audience." Yikes!

Use macOS VMs in VMware Fusion in retina mode

I use VMware Fusion often—I have virtual machines that span Mac OS X 10.6 to macOS 10.12.4 beta. I use the more-recent of these for supporting our customers on older versions of the OS, and keep the really old versions just for nostalgia purposes. (I have a bunch of non-macOS virtual machines, too, but they're not relevant to this tidbit.)

In all the time I've been using Fusion on my retina Macs, though, I've never enabled this setting…

…well, I enabled it once, but turned it off, because the end result was too small to see: In Retina mode, every pixel is an actual pixel, not a doubled pixel. On my 27" iMac, that meant the macOS VM thought it was running at (for example) 2560x1600 instead of a retina resolution of 1280x800. VMware even warns you of this in their Knowledge Base:

Mac OS X running in a virtual machine is limited to an approximate resolution of 2560 x 1600, and treats the display as a standard DPI device. This makes the text and icons to appear small in the OS X interface.

However, today I stumbled across this solution from Patrick Bougie—and it's brilliant in its simplicity. Patrick's post has all the details; I'll reproduce them here in abbreviated form, just in case his page ever vanishes.

Edit long Terminal commands in a visual editor

Here's a quickie tip for those of us who occasionally string together complex commands at Terminal's prompt: You may want to add this simple line to your .profile (or whatever init file you use):

set -o vi

What does it do? It tells Unix/Terminal to set the input line editor to vi. When might this be useful? Let's say you've typed a long command, like the one to launch a background screen saver:

/System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -module "Arabesque" -background &

Before you hit Return, you notice a couple of typos early in the command. You could use cursor movement keys to move around, of course, but with the above command in place, just press Escape and hit v: The entered command will open for editing in vi. Make your changes, then do the usual :wq vi exit dance, and your edited command will then execute.

Note that if you edit a command but then don't save it (i.e. you press :q!, you may have to hit Return on the command line to get out of an odd "waiting for v to edit" mode. (At least that's the only way I found to return to normal typing.)



An odd fix for ‘jpeg’ vs ‘jpg’ filename extensions

I recently reinstalled macOS Sierra, due to my annoying Bluetooth issues. I hadn't noticed any side effects of the reinstall until I went to save a JPEG image from Acorn.

On save, I noticed that the image's extension was .jpeg rather than what I thought was the usual .jpg. As both of my other Macs save with the .jpg extension, I figured something was messed up on the iMac. So I (of course) tweeted about the issue. A while later, Shawn King replied with this seemingly odd suggestion:

So I tried it, and sure enough, changing the screen capture file format via defaults write com.apple.screencapture type jpg and then restarting the SystemUIServer with killall SystemUIServer changed my default JPEG extension in every app to .jpg.

What's really strange is that I then switched the screenshot format back to png, and the .jpg extension remained. I even went so far as to delete the pref (defaults delete com.apple.screencapture), and still, the extension remains .jpg. So whatever change occurred when switching the default screenshot format, it appears to be permanent.

I tried the same trick for the .tiff extension (which I rarely use, so it doesn't bother me as much), and it sort of worked: Captured screenshots got a .tif extension, but images saved from apps still got the four-letter .tiff extension. Weird.

If anyone knows exactly what's going on with the .jpeg vs. .jpg extension, I'd love to hear the explanation.



Watch a screen saver in the background

Another oldie but goodie, and it's best demonstrated by example:

Yes, that's a screen saver running in the background, behind whatever work you're doing. And if nothing else, it's a great example of the progress of our CPUs and GPUs since 2002. In the original hint, I noted:

On my G4/733 with the GeForce3, this is simply amazing. The new "flurry" screensaver is running right now on the destop at 1600x1200 in thousands, iTunes is playing, the ink recognition floater is open, and yet the CPU utilization is averaging at or below 50% of thereabouts

Today, I'm testing it on a 5K iMac (5120x2880) with a second connected 4K (3840x2160) display—a total of 23,040,000 pixels, or 12 times as many pixels as in 2002—with Flurry running on both screens, and the CPU usage is somewhere around 10% to 15%. (Flurry does send the iMac's fans into a tizzy, though.) Other screen savers are even less intensive, and don't send my iMac's fans into high gear.

I can't imagine actually working this way for very long, but it is kind of interesting. Here's how to start (and more importantly, perhaps, stop) a background screen saver.

Open URLs in either frontmost or default browser

Between Many Tricks and this blog, I spend a lot of time in browsers. Most of the time, I use Safari, but I do occasionally work in Chrome and Firefox, too—most often to check how a page looks or functions.

I keep my "permanent" bookmarks in Safari, and don't presently use any sort of cross-browser sync. (I used to use one, but had a lot of trouble with duplicates, so I stopped.)

I wanted a way to open a limited number of URLs in either Safari (if that's what I was in, or if I wasn't in a browser), or in the frontmost browser, if that browser were frontmost. I could just create the subset as bookmarks in each browser, but if I wanted to add or remove a page from the list, I'd have to do so multiple times.

In the end, I came up with a set of Keyboard Maestro macros that do exactly what I want. I access my short list of multi-browser URLs via Keyboard Maestro's pop-up palette, as seen at right.

This appears when I press ⌃1; after that, a single digit opens the desired URL. But how does it know whether to open the URL in Safari or one of the other browsers? It takes one helper macro, then one macro for each URL that I want to open in this manner.

One possible solution to macOS Sierra Bluetooth issues

A while back, I wrote about some very annoying Bluetooth issues in macOS Sierra: My headphones would pop and crackle when I moved my mouse around, and the mouse, keyboard, and/or trackpad would randomly disconnect and reconnect.

The other night, due to some stupidity on my part1I installed an app I suspected might have infected my Mac. It was a false alarm., I felt it was time to reinstall macOS Sierra. I logged into my other admin account, launched the Mac App Store, and then reinstalled macOS Sierra2There are other ways to reinstall, i.e. from the recovery partition; they're detailed on the support page..

The nice thing about the reinstall is that it's nothing like a reinstall from days of yore—you're not starting from scratch, so you won't have to reinstall everything when done. Apple makes this clear on the support page:

You can install macOS over the same version or earlier version, without removing your data. You don’t need to remove or disable the existing system first.

I say this with crossed fingers, but it seems that this reinstallation has potentially solved my Bluetooth issues. For the last two days, I've used my Bluetooth headphones without any static issues at all. In addition, none of my Bluetooth devices have disconnected. There is one comment from slajax on the original article that states this didn't work for them:

I’ve been having the same issue but with the gen 1 track pad and keyboard. I reinstalled the OS, PRAM etc replaced them with the gen 2 key board and track pad and also had the apple store replace the bluetooth antenna but still having the same issue.

If you've reached the breaking point with your macOS Sierra/Bluetooth issues, it might be worth the 30 minutes or so a reinstall takes. But please, if you go this route, make sure you have a good backup first, just in case. And if it works for you, please post in the comments (either here or on the original post), so that others might see, too. I promise to do the same if my now-working Bluetooth turns out to again be not-working Bluetooth.



Make your macOS Dock suck

Now, some may not like the Dock and say it already sucks. But I'm actually referring to a really old hint that ran on Mac OS X 10.0's release date—March 24, 2001.

The hint explained that the Dock has three minimization modes available; back then, you had no choice of which to use. Now we have a choice between two: Genie (the default) and Scale, selectable on the Dock System Preferences panel. If you'd like to see the hidden third mode, Suck, issue these two commands in Terminal:

defaults write com.apple.Dock mineffect suck
killall Dock

Your Dock will restart, and when you minimize a window, it will be sucked into the Dock. The best way to compare these three animations is by watching them in slow motion—hold down Shift1That's called a hidden hint—hold Shift to see any macOS animation in slow motion. while clicking the yellow button on any window. Or just watch this video…

I personally use Scale, though I am surprised that Suck has survived intact over all the intervening years.



Install and use a non-GUI connection speed test tool

Yesterday on Twitter, Dave Hamilton tweeted…

What is this speedtest exactly? And what is brew, you may also be wondering? You may also be wondering why, if you have brew, Dave's command doesn't work…that's because it's actually brew install speedtest_cli…but I'm getting ahead of myself.

speedtest is a command line interface (i.e. Unix app run from Terminal) to the connection speed tests at Speedtest.net—you get the results without the fancy animated graphics. And Brew is "the missing package manager for macOS." In other words, it's an app to help you install (and uninstall) other apps.

Here's how speedtest looks in its default mode—note that I've sped things up greatly for the GIF…

Much nicer to me, though, is the simplified version:

$ speedtest_cli --simple
Ping: 9.482 ms
Download: 94.23 Mbit/s
Upload: 68.66 Mbit/s

No animated dots, just three lines with the results. As you might expect if you read here regularly, I also wrote a Keyboard Maestro macro (of course I did!) that makes it really easy to run the simple version of the test, and does some editing of the output to simplify the display:

If you'd like to install speedtest (and maybe add the macro)—even if you don't want to install Brew to do so—keep reading…
