Customize The Launchpad, Mission Control And Login Screen Backgrounds With Lion Designer

Since Lion launched we’ve covered a few hacks that describe how you can change Mission Control’s and Dashboard’s background, as well as how to change the background of folders in Launchpad - but most of them have required some level of manual file editing and replacement. Fortunately, developer Moritz Wette has made it a whole lot simpler to customize the look of Lion with his app, Lion Designer.

Lion Designer lets you customize the Mission Control, Dashboard, Launchpad folder and the login screen background as well as the Launchpad folder icon. The developer suggests using PNG images that are at the resolution of your screen or are images that can tile - otherwise you’ll end up with something that looks messy. Though if you don’t like how something looks after you’ve changed it, or something has gone wrong, you can easily click the reset button and Lion Designer will return it to the stock look. I gave the app a quick spin and found it worked fine, with my Dashboard now displaying the familiar and soothing linen pattern. Lion Designer is available for free, but be sure to send over a small donation to Wette if you find the app useful to you.

If you’re looking for some other apps to tweak and customise OS X Lion, have a look at these apps that we have covered in the past:

  • Lion Tweaks - Lets you turn various features in Lion on or off, examples include removing the system Window animation, disable spelling correction, enable permanent scrollbars and many more.
  • Launchpad-Control - Hide any app you want from being displayed in Launchpad
  • LaunchpadCleaner 2 - Also allows you to hide apps from Launchpad as well as some more in-depth features.

Apple Pushes Back Mac App Store Sandboxing Requirement To March 2012

In an email to developers today obtained by iClarified, Apple has informed them that all apps submitted to the Mac App Store must implement sandboxing by March 1st, 2012. Originally Apple had told developers that the sandboxing requirement would take place this month. It isn’t entirely clear why Apple has delayed the introduction of this requirement but it does give developers a few more precious months to implement the restriction and resolve all issues that it might cause for their app.

In the email Apple notes; “Sandboxing your app is a great way to protect systems and users by limiting the resources apps can access and making it more difficult for malicious software to compromise users’ systems”. For those who aren’t familiar with the technical ‘feature’, John Siracusa has a great (and in-depth) discussion of the feature in his Mac OS X 10.7 Lion review on Ars Technica. In short, sandboxing restricts the number of actions that an app can do so that if the software is compromised, the amount of damage it can do is greatly minimised.

In Lion, the sandbox security model has been greatly enhanced, and Apple is finally promoting it for use by third-party applications. A sandboxed application must now include a list of “entitlements” describing exactly what resources it needs in order to do its job. Lion supports about 30 different entitlements which range from basic things like the ability to create a network connection or to listen for incoming network connections (two separate entitlements) to sophisticated tasks like capturing video or still images from a built-in camera.

In its email to developers, Apple also notes that if an app requires access to “sandboxed system resources”, the developer must also include justification for why it needs those entitlements when submitting the app to the Mac App Store. Finally, Apple notes that it is willing to offer developers additional, temporary, entitlements if the app is being re-engineered for sandboxing - but only on a short-term basis.
