Apple Acknowledges “White Lines” Issue in Mission Control on Retina Macbook Pros

Fix offered in “the latest Mac OS X updates for your computer,” says the company

A new support document has appeared on Apple’s web site titled “Macbook Pro (Retina, 13-inch, Late 2012): Subtle white lines may appear in Mission Control.” The Mac maker acknowledges a graphical glitch on 13-inch Retina systems, offering a fix.

The Cupertino giant says “When you use Mission Control on your Macbook Pro (Retina, 13-inch, Late 2012), you may notice a few fine lines appear on the desktop,” as shown in the image above (courtesy of Apple).

Acknowledging the issue, the company says users can easily fix it by installing fresh updates from the Mac App Store.

“To resolve this issue, install the latest Mac OS X updates for your computer. See OS X: Updating OS X and Mac App Store apps for instructions,” reads the documentation.

Apple doesn’t specify exactly what updates these users are required to install. However, the company trusts that the Mac App Store will recognize users’ system configurations, determining whether or not they’re affected by the bug.

In case they are affected, users will be presented with the option to update their software using one of the latest releases from Apple.

A good first guess would be MacBook Air and MacBook Pro Update 2.0, which Apple rolled out earlier this week saying it “includes graphics performance and reliability enhancements and improves compatibility with some USB devices.”

However, the knowledge base article describing the contents of the update also states that “This update is recommended for all Mac notebooks introduced in June 2012.”

Retina, 13-inch, Late 2012 doesn’t fall in this category, and Apple fails to mention the name of the patch users should see listed in the Software Update section.

For what it’s worth, affected customers can follow Apple’s instruction set and see where it takes them.
