There has been plenty of evidence that Apple is planning for ultra high resolution Mac displays. In July 2011, we first detailed the existence of a new "HiDPI" mode in OS X Lion. This HiDPI mode was put in place in anticipation of the day that Macs would have double-resolution (4x the number of pixels) "Retina" Displays.
As on the iPhone, Apple's plan was to make it easier on developers to jump to exactly 2x the linear resolution. For example, a 1440x900 pixel screen would go straight to 2880x1800 pixels. This would allow applications to automatically scale up by a factor of two without necessarily having to include high resolution artwork. Apple already made such a transition when going from the iPhone 3GS's screen (320x480) to the iPhone 4's Retina Display (640x960).
In iOS, Developers can include high resolution versions of their artwork designated by the "@2x" suffix. From the developer documentation:
The inclusion of the @2x modifier for the high-resolution image is new and lets the system know that the image is the high-resolution variant of the standard image.
A look at some of the resources from Apple's new Messages app shows several graphics that come in multi-part TIFFs that include regular and double resolution versions. In fact, if you look at the information embedded within the images, you can see the resources were at one point named in the same "@2x" convention. So, it seems Apple's Messages App is already building in support for Retina displays on the Mac.
Rumors have even suggested that we might see our first Retina Display Macs in 2012. One early report claimed Apple was working on a 2880x1800 MacBook Pro for the middle of this year.
Apple is expected to launch an all-new ultra-thin iPhone 17 Air later this year, and while there have been plenty of rumors about the camera's overall design and thinness, we haven't heard any details about the device's weight and battery capacity until now.
According to the leaker going by the account name "yeux1122" on the Korean-langauge Naver blog, the 6.6-inch iPhone 17 Air has a weight ...

Google made waves yesterday by showcasing a set of lightweight smart glasses featuring deep Gemini integration and an optional in-lens display. The demo has reignited interest in Apple's own smart glasses project, which has been the subject of rumors for nearly a decade. Here's a recap of where things stand.

The Worldwide Developers Conference (WWDC), Apple's annual developer and software-oriented event, is less than three weeks away. We haven't heard a great deal about macOS 16 ahead of its announcement this year, so we could be in for some major surprises when June 9 rolls around. Here's what we know so far about the next major update to Apple's Mac operating system.

Love it - hopefully in a month I will hold an retina display iPad in my hands and maybe by end of the year a retina display MacBook. Only thing missing than to my happiness is a version of iBooks on my Mac (yes, I think there is a use for at least some books on the computer).
I just removed the app. It crashed and even my whole Mac froze!
You are aware that the beta label means 'likely to crash or have problems' ... If you are not comfortable with that, don't even bother installing. I hope you filed a bug report with crash log so that Apple can fix the problem (which is the point of beta releases)
that said, I installed it on three of my macs without any problems (Just wish I also could add my phone number to the list, not only my emails - messages send to my phone number don't show up).
