Does your service provider differentiate between standard or "premium" IDD and "budget" IDD like mine does? Typically, the standard + international call prefix will default to the premium option, but to use the the cheaper option, usually via voice-over-IP (VoIP), one has to specific a different carrier-defined prefix, e.g. 12300 (I just made this up, check with your telco). I can't find a built-in way to do this on iOS... enter the Workflow App!

Remember the time I waxed lyrical about using Google Sheets to track my stock portfolio? Well, it's going to be a "standard feature" of spreadsheets soon, with the introduction of the capability to retrieve stock data with today's update of Numbers on iOS (3.1) and macOS (4.1).

Here's how to retrieve and display the latest exchange rate for two currencies with the Workflow App (though one could just use Numbers on iOS or macOS too).

I've been playing with the Workflow.is App recently, and this one is pretty cool - using Workflow to scan and generate a QR Code with Contact information.

I love that iOS includes the Oxford Dictionary. I dislike that iOS has not provided a simple way for me to lookup a word, unlike on macOS, which has Dictionary. Here's the fix with the Workflow.is app!

Apple acquired Workflow today, and Workflow is now free in the App Store! Workflow (http://workflow.is)is a powerful yet simple rule-based automation tool. One pre-built workflow is to lookup your next calendar meeting, retrieve the location if there is one, and pop up directions in Maps - all this from a single button click.

If you are new to Workflow, here is a short tutorial to use Workflow to track travel expenses.

Since 2012, all apps on the Mac App Store must run in an app sandbox, which restricts access to system resources unless explicitly required. The secure sandbox isolates the app and defines access controls, protecting users from malicious code with undesired behaviour.

Here's how to setup a sandbox for an app downloaded from outside the Mac App Store.

Want to extract files from a macOS installer package with a .pkg extension?

Wine 1.9.22 development (dated Oct 28, 2016) has been released! See the release notes for changes. Alas, I encountered errors trying to compile it "on top" of the Wine 1.9.21 installation, following the steps from my post Compiling Wine from scratch. I spent a whole day searching for the problem, and resolved it as below.

So a couple of days ago, I documented how I compiled Wine 1.9.21 with Retina Mode from scratch on macOS Sierra. After that I though I might as well figure out how to bundle all these files into a .app bundle, which Finder presents as if it were a single file.

I have been using WineBottler to run my favorite Windows applications in macOS. Here, I describe how I compiled Wine from scratch and configure for my MacBook Pro's Retina Display.

I recently discovered an alternative to remote control my Windows 7/10 desktop PC, instead of using Microsoft Remote Desktop. This method requires a computer with a modern NVIDIA graphics card with GameStream and works with iOS and macOS using a client called Moonlight!

The Magnifier seems like it'd be useful. Here's how to setup the Home button Triple-click with multiple Accessibility Shortcuts and to avoid physically triple-clicking the Home button with the AssistiveTouch floating Home button.

I wanted a simple stock portfolio monitoring tool. I failed to find a simple and free app, but happily discovered that Google Sheets does what I need perfectly!

Apps, even after being removed from the Launchpad or Applications sidebar in Finder, do leave preferences and other files scattered around. Where are they, typically, and how does one find them?

My previous Terminal Tweaks post had an incorrect prompt (PS1) setting, that caused lines to wrap on themselves! This is now corrected, with more details on the color options...

I discovered that Xcode includes a diff tool called FileMerge. Where is it and how do you launch it?

I, like many other iPhone users, turn on AssistiveTouch so that I don't have to press the Home button. Historically, this button has been quick to fail, so using the on-screen icon will save some wear-and-tear. And with iOS 9, AssistiveTouch has become customizable! Shocking (for Apple, not much is customizable)!

To clean install Windows 10, you need more than the product key from an upgraded instance of Windows 7/8. You'll need a file called tokens.dat created during the upgrade process.

Some tweaks to my OS X shell (Terminal.app) that I've found useful.
