macOS Apps

Articles about OS X applications.

See the launch date and time for any app or process

I was working on something with Peter about Moom and its disk usage (it doesn't use much), and I was curious as to just how long Moom had been running on my Mac. I last rebooted my Mac a week ago, but I often quit and relaunch our own apps to run test versions.

Finder has this info, but that requires finding the running app in Finder. I wanted a quicker solution. In Activity Monitor (and ps in Terminal), you can see how much CPU time an activity has taken…

…but that doesn't really help at all with knowing when the app (or process) launched. As long as you're in Activity Monitor, you can get the information by doing the following:

  1. Click once on the app or process of interest.
  2. Press Command-I or click the small 'i' icon in the toolbar.
  3. In the new window that opens, click Sample, then wait.

When the sample is complete, you'll see its output, and included there is the selected item's launch date and time:

...
Analysis of sampling Moom (pid 89861) every 1 millisecond
...
Parent Process:  ??? [1]

Date/Time:       2017-02-15 07:41:18.611 -0800
Launch Time:     2017-02-13 19:44:11.957 -0800
...

That's all fine if you're in Activity Monitor, but a bit of a pain if you need to launch it, find the app, run a sample, etc.

As you might expect, there's another way via Terminal: The lsappinfo command, which queries CoreApplicationServices about any app or process on your Mac.

A possible fix broken search in macOS Mail

Over the weekend, I wrote about my totally useless search in Mail. I got so frustrated by my inability to search in Mail that I decided it was time to for a complete rebuild. I exported all my locally-saved mail, deleted my accounts, quit Mail, trashed its prefs and data files, rebooted, then rebuild it mailbox by mailbox, account by account.

I started with my iCloud account, which I barely use for anything—it has a total of seven messages in the inbox (four of which are iTunes Store receipts), and only 121 sent messages. As a test, I searched for Linea, an excellent drawing app that I had recently purchased. No matches.

At that point, I decided to quit Mail and force Spotlight to rebuild its index overnight. In Terminal, sudo mdutil -i on / will do just that (and take many hours). Today, opened Mail, and search was still dead. Argh! (I had also tried this suggested fix, but it made no difference.)

But doing some random testing today, I discovered a fix! It's a weird fix, but it seems to work:

If I move all the messages from an inbox or local storage folder into a different local storage folder, they'll be indexed and findable. I can then move them back into the inbox or source folder, and they remain findable.
Even more important, newly-added messages seem to be properly indexed, in both the inboxes and the local storage folders.

This doesn't make any sense to me, as any one of my recent actions—rebuilding mailbox indexes, reimporting, and redoing the entire Spotlight index—should have been enough to force a rebuild. But for whatever reason, only manually moving the messages seems to force a rebuild.

Now pardon me while I go back to manually dragging a quarter-million email messages around…



Transport the cursor to the center of frontmost window

My home workspace is a 27" Retina 5K iMac (2560x1440) paired with a vertical 4K display (scaled to view 1440x2560). While I love this setup in general, there's one time it's annoying: When I need to move the cursor between displays, and it's located far away from its destination.

There are many ways to solve this problem, including our own Keymo, which I still use when I want to teleport a drag across displays. But what I really wanted was a fast way to move the cursor to the other display when I switched to a window on the other display—because generally, if I've activated the window, I'm probably going to use the mouse in that window at some point.

Using Keyboard Maestro, it's possible to create a macro to make this happen automatically:

This macro will activate every time you switch applications, and then move the mouse to the center of that newly-frontmost window and highlight its location with a quick circle. Having tested this, however, I can say it's a non-ideal solution: Most of the time when I switch an app, I do not want the cursor to move. I found it more annoying—much more annoying—than useful.

As useless as the above macro is, with one minor change it quickly became one of my most-used macros…

macOS app: Use HoudahSpot for enhanced searches

As I lamented in a recent entry here, macOS Mail search is totally broken for me. I pointed out that I can use Spotlight, but also alluded to a third-party app. That app is HoudahSpot, and it's what I use to not only search Mail, but any time I need a more-powerful search than I can get through Spotlight's interface.

Houdah's UI is a large multi-paned window, with search criteria on the left, results in the middle, and one of file info, Quick Look preview, or text preview in the right-hand pane. Here's how it looked for the same search that failed in Mail:

Using HoudahSpot for a search like this, though, is really overkill—I'd see similar results in Spotlight, because it's a very specific search term that's not going to find a lot of matches. Where HoudahSpot shines is in its ability to build more complex search queries.

On the uselessness of search in macOS Mail

For the last couple macOS releases, I've had nothing but trouble searching in Mail. Note that I didn't write "trouble searching mail," but rather, "trouble searching in Mail." For example, today I needed to find an email from my business partner Peter about a hidden pref in Butler. (I was hoping this pref could help a user who was having problems with the pasteboard in a certain app.)

Update: See this post for a possible solution.

Based on a document on my hard drive, I knew the name of the default was Pasteboard Normalization Interval, but I couldn't remember the syntax of the defaults write command to set its value. So I searched in Mail…

So clearly, no emails in my database contain the words I'm looking for, right? Here's the exact same search, run in Spotlight:

Not one but two email messages match my search, and provided the needed syntax for the command.

Wait, I know what you're thinking: "Ahh, look, it's in quotes!" Doesn't matter; searching Mail for "Pasteboard Normalization Interval" still results in zero matches. Searching on even one word of the phrase, like Normalization, also finds no matches.

Again, I know what you're thinking: "Oh, I bet the Mail index is screwed up." Nope; even after rebuilding the index on all 250,000+ messages in my database, no matches are found. (And yes, I let the index complete its rebuild, which took hours.)

I've heard from others that search in Mail works for them. But it's a no go for me, and I know, for others. So something's wrong, but I don't know exactly what it is, nor how to fix it.

So for now, I have to rely on Spotlight to search Mail…or a third-party app, but more on that in a bit.



macOS app: Test DNS servers with namebench

If you've got a speedy internet connection at home, but it seems slow, it's possible its' not the connection itself but the speed of your chosen DNS server.

To figure out if the DNS servers are part of the problem, check out namebench, a DNS server benchmarking app. namebench compares your existing DNS servers to a large list of other DNS servers, and shows you how they all perform.

When namebench launches, you'll see a window populated with your current DNS server addresses, and a few other settings you can modify:

Click Start, then go ahead and find something else to do for a while—the benchmarking process may take 15 minutes or more, depending on how many name servers it can see.

macOS app: BackupLoupe examines Time Machine backups

I'm somewhat paranoid about backups—I have many of them, both online and offline, onsite and offsite. I test my backups to make sure they're good. In short, I do my best to make sure a hardware failure or natural disaster won't take out my data.

My backup strategy includes Time Machine, mainly for recovering from "oh crud I didn't mean to delete that!" moments. We also use it, via a Time Capsule (RIP, sigh), to back up our laptops.

While I love how Time Machine works, I dislike that it doesn't tell you anything about a given backup other than how big it was. Enter BackupLoupe, a $10 "honorware" app. BackupLoupe examines your Time Machine backups and computes a "diff" for each one, letting you know exactly what was backed up in a given run:

Each backup is color coded—on the left of each backup's name, the color indicates the size of the backup, and on the right, the deviation of that size from the norm.

Transforming text via Keyboard Maestro

Recently, Melissa Holt wrote about transforming text via the Transformations menu. After seeing this article, a reader named Hunter wrote to me with this comment:

Today in The Mac Observer Melissa Holt wrote about using the TextEdit/ Edit/ Transformations command to change the case of a sentence or paragraph. However, there is no option to perform, "Sentence Case", i.e., capitalize the first letter of the first word, and keep all other words in lower case.

Is there a way in Terminal, or maybe Keyboard Maestro to add this option to Transformations? It seems to me that the given choices have rather limited uses.

In addition to not offering sentence case, the Transformations menu has a few other drawbacks:

  • Not all apps have a Transformations menu.
  • Only three very basic transformations (upper, lower, capitalize) are supported.
  • The transformations are buried in a sub-menu, requiring lots of mouse navigation to reach.

While I don't believe it's possible to modify the Transformations menu, it's pretty easy to use Keyboard Maestro to build a "Sentence Case" transformation…or more usefully, as seen at right, a palette with many more transformations. Unlike the Transformations menu, the Keyboard Maestro solution will work in any app where you can copy and paste text.

Create a workload for your CPUs

Over the weekend, I was testing how some of our apps work when the CPUs are busy. One way to load the CPUs is to rip a Blu-ray disc, but I was looking for a more controllable CPU load.

A quick search through the Mac OS X Hints archive (use this tip to search the site) found the answer from 15 years ago: Just say yes in Terminal to generate sizable CPU loads…

More specifically, use this command in Terminal:

yes > /dev/null &

If there's an award for strangest Unix utility, yes might just be the winner. All it does is output y (or whatever you list after the y; the man page suggests an expletive) until you kill the task.

The above command sends the output (via the > redirect) to the null device, which discards it. The ampersand sends the job to the background, so you get your Terminal prompt back.

You can run this command multiple times, each loading the CPU even more heavily (the screenshot shows three yes tasks running). Keep an eye on Activity Monitor to see just how much CPU it takes—as shown above, it does a great job at loading the CPU.

You can kill the tasks by issuing the command killall yes in Terminal, or by quitting Terminal—you'll be told that quitting will terminate the tasks.



How to make Sims 3 work in macOS Sierra

When we upgraded all our Macs to macOS Sierra, my daughter was upset because Sims 3 broke. After much scouring of the internet, I found the solution and tweeted about it:

It dawned on me, though, that if that forum post ever vanishes, I'll be in trouble with future new Macs and/or reinstalls, so I thought I'd document it here, too. Read no further unless you (or a family member) play Sims 3 and want to get it working in macOS Sierra. And really, try the linked forum post first; this is just a backup plan.
