According to a recent KnowledgeBase article published from Apple, it’s a really bad idea to try installing Snow Leopard on one of Apple’s newly-released Mid-2011 MacBook Airs, as it can cause the machine to stop functioning properly.

Macbook Air Os Download

OS X Yosemite 10.10.2 is the earliest OS supported on your 2015 MacBook Air. Mac OS X 10.6 Snow Leopard is too archaic (released in 2009) and you won't be able to boot into it on your 2015 MacBook Air. Here is how to change your Mac’s name. This method works on both OS X Lion and Snow Leopard. Your Mac’s computer name is used to identify it on the network. By default, other computers will see your Mac as something like “Tasman Hayes’s MacBook Air“. I like to change it to something simple like “tazair“. To change the Mac’s name.

According to the article, installing a version of OS X that was released before the new MacBook Air could result in the following symptoms:

If you try to install a version of OS X (Snow Leopard or Lion) that was released before MacBook Air (Mid 2011), these symptoms may appear:

• The computer begins to start up normally to a gray screen with the Apple logo, then switches to display a progress indicator (a spinning gear) for a few seconds. Then the built-in display changes to black and the LCD backlight remains lit. This symptom usually appears when you attempt to start up with a version of Mac OS X 10.6 Snow Leopard or earlier.
• A prohibitory sign (a circle with a line through it) appears on the screen. The computer then powers off after about a minute. This may occur if you install a version of Lion other than the version originally installed on your MacBook Air.

The issue reportedly only affects the new MacBook Airs, while no mention has been made of Apple’s new Mac Minis. Fortunately, if you’ve made this mistake and are now stuck with a dysfunctional MacBook Air, Apple does provide a solution:

Reinstall the proper operating system build by restarting the computer while pressing and holding the Command and “R” keys. The right revision of Mac OS X for this computer should be available for installation through the Mac OS X Utilities pane that opens.

Further, the article points out that you can verify if you have the wrong version of OS X Lion by staring your computer in Verbose Mode, and Apple provides instructions for how to do that:

– Shut down the computer.
– Restart the computer while you press and hold the Command and “V” keys.
– The text on the display should say, “This version of Mac OS X is not supported on this platform!”.
– Exit verbose mode by pressing and holding the power button until the computer shuts down.

The KnowledgeBase article then ends by providing some sage advice to the reader: Never install a version of the operating system released before the computer. For more information, you can read the entire article here.

Mac Os X Snow Leopard Requirements

Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some other product that you want to use with your Mac? Which versions are earlier (older) or later (newer, more recent)? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You should see the macOS name, such as macOS Mojave, followed by its version number. If you need to know the build number as well, click the version number to see it.

This example shows macOS Catalina version 10.15 build 19A583.

Which macOS version is the latest?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps that are installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.
