Basically, a Mac application has a
.app
extension, but it’s not really a file — it’s a package. You can view the application’s contents by navigating to it in the Finder, right-clicking it and then choosing “Show Package Contents”.The internal folder structure may vary between apps, but you can be sure that every Mac app will have a
Contents
folder with a MacOS
subfolder in it. Inside the MacOS
directory, there’s an extension-less file with the exact same name as the app itself. This file can be anything really, but in its simplest form it’s a shell script. As it turns out, this folder/file structure is all it takes to create a functional app!Carbon on Mac OS X is effectively deprecated - it does not and will not support 64 bit apps. If you really really want to use c, use Qt Creator Which is now free and the trolltech SDK includes Qt 4.5, which while it is a c framework it internally uses Objective-C to interact with MAC OS X, so then you are not limited by Carbon. Defaults write com.apple.dock expose-animation-duration -float 0.12 && killall Dock. Make Hidden App Icons Translucent in the Dock. Hiding open apps has long been a useful feature of Mac OS, but by default there’s no easy way to tell what’s hidden and what’s not. To understand how to create an explicit app ID, create provisioning profiles, and enable the correct entitlements for your application, so you can sell your application through the Mac App Store or use iCloud storage, see App Distribution Guide. For a general survey of OS X technologies, see Mac Technology Overview.
Apple includes some useful handwriting features in OS X. Based in part on some of Apple’s handheld software for its ill-fated Newton (one of the first personal digital assistants, released before its time), the handwriting recognition in OS X gives you the capability to write text on a compatible tablet in your favorite applications.
Enter appify
After this discovery, Thomas Aylott came up with a clever “appify” script that allows you to easily create Mac apps from shell scripts. The code looks like this:
Installing and using appify is pretty straightforward if you’re used to working with UNIX. (I’m not, so I had to figure this out.) Here’s how to install it:
- Save the script to a directory in your
PATH
and name itappify
(no extension). I chose to put it in/usr/local/bin
, which requires root privileges. - Fire up Terminal.app and enter
sudo chmod +x /usr/local/bin/appify
to make appify executable without root privileges.
After that, you can create apps based on any shell script simply by launching Terminal.app and entering something like this:
Just at least wanted something that would do the basics. Mac midi controller app. Reason is a bugger so there is little to choose from that will do job.' So, lots to learn but with the covid virus to deal with like many others I am going nowhere soon!
Obviously, this would create a stand-alone application named
Your App Name.app
that executes the your-shell-script.sh
script.After that, you can very easily add a custom icon to the app if you want to.
Adding a custom app icon
- Create an
.icns
file or a 512×512 PNG image with the icon you want, and copy it to the clipboard (⌘ + C). (Alternatively, copy it from an existing app as described in steps 2 and 3.) - Right-click the
.app
file of which you want to change the icon and select “Get Info” (or select the file and press ⌘ + I). - Select the app icon in the top left corner by clicking it once. It will get a subtle blue outline if you did it right.
- Now hit ⌘ + V (paste) to overwrite the default icon with the new one.
Note that this will work for any file or folder, not just
.app
files.Examples
Chrome/Chromium bootstrappers
I like to run Chrome/Chromium with some command-line switches or flags enabled. On Windows, you can create a shortcut and set the parameters you want in its properties; on a Mac, you’ll need to launch it from the command line every time. Well, not anymore :)
The
&
at the end is not a typo; it is there to make sure Chromium is launched in a separate thread. Without the &
, Chromium would exit as soon as you quit Terminal.app.Launch a local web server from a directory
Say you’re working on a project and you want to debug it from a web server. The following shell script will use Python to launch a local web server from a specific directory and open the index page in your default browser of choice. After appifying it, you won’t even need to open the terminal for it anymore.
More?
Needless to say, the possibilities are endless. Just to give another example, you could very easily create an app that minifies all JavaScript and CSS files in a specific folder. Got any nice ideas? Let me know by leaving a comment!
