Inside macOS, Apple started using the concept of points, rather than pixels, as its way of measuring screen dimensions. For older non-Retina displays, Apple decided that pixels and points would be the same size. So all the previous conventions about screen layout still worked. On the new Retina displays, however, Apple said that 1 point equalled 2 pixels, so there are twice as many pixels as points in each direction.
So when a developer creates a dialog button as 18 x 90 points , it is still 18 x 90 pixels on a non-Retina display, but 36 x pixels on a Retina display. Because the Retina display has double the pixel density, the button on both the non-Retina display and the Retina display have the same apparent physical size, slightly less than 1 inch wide.
Apple updated all the controls and text drawing so that buttons and text drawn on a Retina display draw using twice as many pixels and all applications continue to work as before without change. But graphics programs like Rhino need updated to take advantage of the new Retina displays.
As we mentioned, macOS now generally works by using points for its drawing. But when Rhino is drawing your model in a view, it needs to know the size of a view in pixels, not in points. So Rhino queries macOS to determine this, and uses the appropriate pixel values when drawing. If you visually compare your model on a non-Retina display like a MacBook Air with the same Rhino model on a Retina display, you will see that the Retina version is much crisper and clearer.
Rhino is drawing four times as many pixels when drawing to a Retina display. Changing this is generally a bad idea for Rhino for Mac. For example, do not use the scaling setting below. See the comment Using a scaled resolution may effect performance? That is very true in Rhino for Mac. This panel lets you change the dimension of your display in points , not in pixels. Obviously you cannot change the number of physical pixels in your display.
If you think the screen resolution is in pixels, Apple's presentation on this control panel can be confusing. The screen resolution presented in System Preferences is actually in points. To measure the difference these settings make, we instrumented Rhino to report the actual viewport sizes. We started Rhino and made the Rhino drawing window full screen and a single viewport.
The MacBook Air and inch MacBook Pro the one with the optical drive were the only holdouts -- though it looks like the inch MacBook Air is sticking around for now. Now, Retina is the new normal. It's not special anymore -- but it is a pretty incredible bump in clarity if you haven't experienced it before. Check out all of today's Apple news here. Update at p. PT: It looks like the inch MacBook Air is sticking around after all, so we may still have one non-Retina screen to choose from.

Various factors play into the weight difference, including that iconic tapered design. Despite all of the display improvements, and the reduced footprint, Apple rates the new MacBook Air similarly to its predecessor when it comes to battery life. Even though the battery in the new MacBook Air is smaller, The MacBook Air features a single processor option — a 1.
Compared to the chips in the previous MacBook Air, which were 15W, this processor is designed to draw less power. For most people in the market for a MacBook Air, I think the 7W i5 processor is okay, and will do everything you need for day-to-day tasks.
Word processing, web browsing, and media consumption will all perform well on the MacBook Air. If you set the right expectations, even light video editing and other tasks that typically require more power, will perform decently. Cinebench R15 results paint a similar picture. Neither machine is impressive when it comes to graphics performance, but the MacBook Pro is the winner by default. For me, as someone who works with video on a day in and day out basis, Final Cut Performance is a big differentiator.
For most people, the answer to that question is: No. Keep in mind that when you configure a larger SSD, the write speeds will significantly improve. The new keyboard features keys that are individually backlit, which looks more uniform when typing in dimly lit settings. The updated keyboard addresses some of the well-documented issues that plagued previous versions, but it will still take some getting used to for anyone coming directly from the previous MacBook Air.
Alongside the keyboard is a stand-alone Touch ID sensor, the biometric technology that lets users quickly unlock, authenticate with macOS and third-party apps, and make Apple Pay purchases. For more information about the Apple T2 security chip, be sure to read our Mac mini review.
The MacBook Air was the last Apple laptop to use the diving board trackpad mechanism, so this is another welcome change. Along with the speaker improvements, a new three-array microphone makes an appearance as well. The microphones are geared towards lending better sound input for FaceTime calls, and improving the accuracy of Siri communication. The new MacBook Air includes a pair of Thunderbolt 3 ports on the left side of the keyboard, which also happen to be the same ports used for charging the machine.
The downside is that Apple has gone all-in with Thunderbolt 3, and left other handy ports like an SD Card reader behind. As a result of the adoption of Thunderbolt 3, the MacBook Air ditches the popular MagSafe connector for charging. It means that one of the USB-C ports will be occupied any time you need to charge the machine.
It also means that you lose the utility that MagSafe, a magnetic-attaching power connector that easily disconnected if someone happened to trip over the cable, brought to the table. Depending on how you used the previous MacBook Air, the model is a downgrade in some ways. Performance on the new MacBook Air is better than the previous-gen model, but it may not be as drastic of an improvement as one might have been hoping for in a MacBook Air redesign. But make no mistake, the MacBook Air is a major upgrade over its predecessor in a lot of ways.
The IPS-enabled Retina display is a welcome presence, providing much-improved viewing angles and better colors as well. What are your thoughts on the new MacBook Air?

Change the resolution of your display Your Mac automatically chooses a default resolution that is optimal for your display. Click Displays. If you have multiple displays connected, click Display Settings, then select your display.
Select Scaled, then select any of the four or five scaled resolutions, depending on your Mac model. With scaled resolutions, text and objects can appear larger and more visible, or smaller to provide more space for windows and apps.
If you're also using an external display If you're using an external display to extend your desktop, you can choose a preferred resolution for each display. Using apps with a Retina display If an app looks different than you expect on your Retina display or high-resolution external display, try opening the app in low-resolution mode: Quit the app. Open the Applications folder.
Click the app once to select it, then choose Get Info from the File menu. When your Mac is using the Apple-supplied Windows Support Software, Windows starts up with the maximum dpi pixels it supports, which is dpi, or percent magnification. As a result, items on the display appear small, with a lot of space. You can use the Windows Display control panel item to adjust this setting in Windows.
