Glimpses Icon

Today, Glimpses v2.1, an app that creates Still Motion Videos in just a few clicks, is available for download from the Mac App Store.
It’s a free upgrade for everyone who purchased it before.
A free, 15-day trial is available for download here, even if you’ve tried it before.

What Is Glimpses?

When you want to show your awesome photos from your recent vacation but there are just too many, you can either sort through them and heavy-heartedly decide which ones to toss aside, or you show them all – with a Still Motion Video.
Still Motion Videos show photos in very rapid succession, usually for the fraction of a second. Mix that with a soundtrack, and you can make your video action-packed and powerful, or mellow and soothing. Or even both.

Glimpses lets you create such high-quality videos with just a few clicks.
Import your photos (from your Photos.app library, a hard drive, Flickr or Instagram), add one or more soundtracks and you’re set – Glimpses figures out the rest.
The app creates your video in a smart way:

  • The video’s resolution (ranging from 240p to 4K) will be calculated by looking at the smallest photos you supply
  • Its duration is based on the amount of photos you imported, and the duration of the soundtracks you supplied
  • Soundtracks that turn out too long will automatically fade out smoothly at the end of your video, whereas short soundtracks can be looped
  • Pillar- and letterboxes can be eliminated, if the photo’s resolution allows for it
  • Due to built-in facial recognition, photos are positioned in a way that faces aren’t outside of the video’s frame

However, control is always at the user’s fingertips. For example, soundtracks can be edited so only your favorite part of it is used, in an easy-to-use, yet powerful way:

Additionally, every other aspect of your video can be manually set up:

What’s New in v2.1?

  • Improves integration with macOS by providing a QuickLook plugin that offers an easier and quicker way to identify Glimpses project files
  • Improves integration with Photos.app by supporting drag and drop from the app and offering a Share Extension so photos can be imported to Glimpses without leaving Photos.app
  • Photos can be edited using external editors
  • Shuffle photos to add a random touch to your video
  • Performance improvements, refinements and bug fixes throughout the app

In my app ScreenFloat, I use the command line tool screencapture via NSTask to create screenshots. On OS X El Capitan and earlier versions of Apple’s operating system, this worked perfectly fine. Now, on macOS Sierra, I’ve been getting reports that screenshot creation didn’t work anymore, so I investigated.

At first I thought it might be the keyboard shortcut API that has undergone some changes, but that doesn’t seem to be the case, as I saw something actually occurred when I pressed the keyboard shortcut – Xcode’s console printed:

screencapture: cannot run two interactive screen captures at a time

Since I was absolutely sure I’m not launching screencapture via NSTasktwice, I took to Console.app to see if anything unusual was reported there. And there it was:

Sandbox Violation of ScreenFloat on macOS SierraThe output in Console.app when trying to launch an interactive screencapture with NSTask.

deny mach-register

So registering a global Mach service is denied on macOS Sierra. In the back of my mind, I remembered a temporary exception entitlement, but it wasn’t quite the same – com.apple.security.temporary-exception.mach-lookup.global-name. I tried adding it to ScreenFloat’s entitlements file, with com.apple.screencapture.interactive as its value (this temporary entitlement expects an array of string values), but that didn’t help – the same denial and console output occurred. On a hunch, I tried using …mach-register.global-name instead of …mach-lookup.global-name and – tada – it worked!

So I’m all set, right? Well…

Temporary Exception Entitlements

Apple offers a couple of temporary exception entitlements. They may or may not be granted to your app during Apple’s review process. But going through the list, it’s clear that …mach-register.global-name is nowhere to be found, so it’s kind of a private entitlement – which makes it even less likely for it to be granted to your app.

Digging Further

Seeing as the sandbox denial points explicitly to com.apple.screencapture.interactive, not just com.apple.screencapture generally, I tried creating a non-interactive screencapture session with NSTask. To my surprise, it worked – without the entitlement.

So I tried a different command line utility – which. (which will return the executable path to the given command line utility, for example, which screencapture would return /usr/sbin/screencapture). Again, it worked. And again, without the entitlement.

It makes me believe (and hope) that the behavior we see for com.apple.screencapture.interactive is not desired, so I’ve filed a bug report with Apple in the hopes that they can set the record straight soon.

For now, I hope ScreenFloat will be granted the temporary entitlement just so it is functional again on macOS Sierra for the time being. However, if this is in fact the desired behavior, I will have to write my own screencapture utility so ScreenFloat can remain on the Mac App Store.

Bug Reporting

For anyone who’s interested or in a position to view it, here’s the bug report I’ve filed with Apple: rdar://27610157. I do hope to get an answer soon.

Update August 2nd, 2016

As I stated above, com.apple.security.temporary-exception.mach-register.global-name isn’t documented anywhere. Which is also the reason you get an error when trying to submit an app with such an entitlement to iTunes Connect:

ERROR ITMS-90285

So, no dice on the temporary exception. Having to write my own screenshot utility seems more and more likely. I hope I can make it in time for macOS Sierra.

Update September 9th, 2016

The temporary exception is now valid and will go through to Apple’s App Review without a hitch. My own solution is not necessary at this time, but I’m still going to be working on it – you never know.

Yoink Mac App Icon

I’m happy to tell you that today, Yoink 3.2 is available for download from the Mac App Store.
It’s a free upgrade for everyone who’s purchased it before.
You can download a 15-day trial for the app here, even if you’ve tried it before.

What Is Yoink?

Yoink simplifies and improves drag and drop on your Mac.

Simplify.

It simplifies drag and drop by providing a temporary place for files you drag, so you can navigate more easily to the destination of the files.
It’s especially useful when trying to move or copy files between different windows, Spaces or (fullscreen) applications.

Moving a file with Yoink

When you start moving a file in Finder, or app-content like an image from a website, Yoink appears at the edge of your screen, offering a temporary place for you to drag the files to.
Without having to keep the mouse button pressed, you can now get to the destination of your file quicker and easier.

Improve.

Drag and drop is improved in several ways, including:

  • Collect multiple files from different locations you’d like to move to one destination without having to go back and forth
  • Split up a multiple-files-drag so you can move files to different places without having to go back and forth
  • Copy files to multiple locations more efficiently

Customize.

You can customize Yoink’s behavior so it fits in perfectly with your workflow. Aside from having to option to show it at either edge of your screen (at the top, center or bottom), you can set it up to only appear when you drag files to the edge of your screen or to appear directly at your mouse cursor when you start dragging, making drag and drop even faster.

Yoink appearing at the mouse cursor

For applications where you don’t need Yoink, add them to a “blacklist”, so Yoink doesn’t interfere with your work.
A keyboard shortcut (by default, F5) lets you manually show or hide it, should you need it anyways.

What’s New in Yoink 3.2?

Force Touch Support

Force Touch in Yoink allows for quick actions, i.e. selecting all files, revealing files in Finder, QuickLooking files, splitting up Stacks and pinning files to Yoink, all available with one Force Click.

Yoink's Force Touch Preferences

For instance, Force Touch makes dragging out all files at once a much nicer process than before. Force Click onto one file and all are selected. Ease up one pressure level and start to drag, and you’ll drag all files instantly.
Additionally, Yoink can give you haptic feedback when dragging to it, so you know when you’ve entered Yoink’s window with files.

Deletion Warning

Yoink does not keep a copy of the files you add to it behind the scenes, so it’s important for users to know that if they Trash a file that’s in Yoink, it will be gone if it’s deleted.

Trash warning in Yoink 3.2

This one-time-per-app-launch warning notifies the user about what’s going on.

UI Enhancements

In previous versions of Yoink, when you moved your mouse cursor over a file, this happened:

Yoink 3 Icon Behavior

Some users felt that this results in a moving target (as the icon moves away), and that is definitely a bad user experience (in my defence, I didn’t think of it creating a moving target, because not only the icon, but also the background can be dragged).
Anyway, point taken, I’ve changed it to a simpler, and in the end calmer, animation:

Yoink 3.2 Icon Animation

What you can also see in the two GIFs above, I’ve changed the lock icon so it’s easier to tell if a file is pinned to Yoink or not.
Speaking of the lock, I’ve added a new animation that will let you know that the file can not be removed because it’s currently pinned to Yoink:

Yoink Lock Icon Jiggle

Further Improvements

  • File paths can be copied from Yoink’s contextual menu
  • Reduce Motion Setting
  • Text snippets can now contain images
  • Performance and resource management improvements when accepting files, dragging files out, clearing all items, splitting up stacks, opening the “Open With” menu
  • When Yoink is shown on a different screen than the mouse cursor, the keyboard shortcut (by default, F5) summons it to the screen of the cursor
  • Yoink reflects changes in the Finder’s “Show all filename extensions” setting
  • Mails dragged from Yoink work again with all applications. To create an event in iCal from a mail message, keep the option-key pressed as you drag the mail out of Yoink
  • When a file is re-saved in Finder, Yoink updates its QuickLook Preview Icon
  • When a snippet is added to Yoink, it has a proper filename instead of “Snippet”
  • And many more improvements and bug fixes throughout the application

Pricing and Availability

Yoink 3.2 is available for purchase on the Mac App Store for the price of $6.99 / £4.99 / €6,99.
It is a free update for existing customers of the app.
You can download a free, 15-day demo version here, even if you’ve tried Yoink before.
Yoink runs on Macs with OS X Lion 10.7.3 or newer. OS X Yosemite or newer is recommended.

In iOS Simulator, you can, via a menu item, quickly simulate memory pressure for the simulated device to see if your app behaves correctly under low memory conditions (releasing caches, cleaning up resources, and so on).

Recently, I had the need for it on the Mac (where such a menu item is not available), while working on an XPC service for Yoink, to see if it terminated properly under certain conditions.

Meet the memory_pressure tool

OS X comes with the Terminal, and with the Terminal come some awesome tools. Among them is memory_pressure. Its man page says it all:

Apply real or simulate memory pressure on the system.

Usage of memory_tool

sudo memory_pressure -S -l critical

What this does is simulate (-S) a memory pressure of a critical level (-l critical).
sudo is needed, otherwise it will probably fail with an “Operation not permitted” error.

memory_tool’s options

-l:   Two levels of pressure are supported: ‘warn’ and ‘critical’.
-p:  For real pressure, this lets you define how much memory should remain free, in percent of total memory.
-S:  Simulate memory pressure, don’t really allocate memory.
-s:   If applying real pressure, this is the duration to wait before allocating or freeing memory.
       If it’s simulated pressure, the system will be maintained at an artificial memory level for this duration.
