Check compatibility

You can upgrade to OS Yosemite on any of the following Mac models. Your Mac also needs at least 2GB of memory and 8GB of available storage space.

MacBook introduced in 2009 or later, plus MacBook (13-inch, Aluminum, Late 2008)
MacBook Air introduced in late 2008 or later
MacBook Pro introduced in mid 2007 or later
Mac mini introduced in early 2009 or later
iMac introduced in mid 2007 or later
Mac Pro introduced in early 2008 or later
Xserve models introduced in early 2009

To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple menu . If your Mac isn't compatible with OS X Yosemite, the installer will let you know.

Make a backup

Before installing any upgrade, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.

Get connected

It takes time to download and install OS X, so make sure that you have a reliable Internet connection. If you're using a Mac notebook computer, plug it into AC power.

The invisible Library subfolder of your Home folder is the repository of everything that OS X needs to customize your Mac to your tastes. If you want to add something to a Library folder, it’s usually best to add it to your Home/Library folder.

You won’t spend much time (if any) adding things to the Library folder or moving them around within it, and that’s probably why it’s now hidden from sight. Still, it’s a good idea for you to know what’s in your Home/Library.

The public Library folder is used to specify preferences for all users on this Mac. This Library folder, however, is all about you and your stuff.

Be cautious with all Library folders. OS X is very persnickety about how the folders and files within it are organized. You can add items to and remove items safely from most public or Home Library folders, but leave the folders themselves alone. If you remove or rename the wrong folder, you could render OS X inoperable.

It’s like the old joke about the guy who said to the doctor, “It hurts when I do that,” and the doctor replies, “Then don’t do that.”

To find your hidden Home/Library folder, do this:

  1. Hold down the Option key on your keyboard.

  2. Click the Go menu.

    The (formerly) invisible Library folder appears in the Go menu as long as the Option key is pressed.

  3. Select Library and release the mouse button.

You should see several folders in the Home/Library folder; the exact number depends on the software that you install on your Mac. You probably have folders called Mail, Safari, Logs, and Preferences, for example.

If you don’t want to have to do this dance every time you want to open your Home/Library, select your Home folder in the Finder and choose View→Show View Options (or press Command+J). Enable the Show Library Folder check box and your Home Library will be visible evermore (or at least until you deselect the check box).

Some of the most important standard folders in the Library folder include the following:

  • Application Support: Some applications store their support files here; others store theirs in the main (root-level) public Library folder.

  • Fonts: This folder is empty until you install your own fonts here. The easiest way to install a font is to double-click its icon and let the Font Book utility handle it for you. Here’s how to install a font manually:

    • To install a font that only you can use: Drag the font file’s icon to the Fonts folder in your Home/Library. The font is available only to this user account (because other users can’t use fonts stored in yourHome/Library folder).

    • To install a font for all users of this Mac: Drag the font file’s icon into the Fonts folder in the public Library folder — the one at root level that you see when you open your hard drive’s icon.

  • Preferences: The files here hold the information about whichever things you customize in OS X or in the applications you run. Whenever you change a system or application preference, that info is saved to a file in the Preferences folder.

    Don’t mess with the Preferences folder! You should never need to open or use this folder unless something bad happens — say, you suspect that a particular preferences file has become corrupted (that is, damaged). Just forget that you know about this folder and let it do its job.

    If you don’t know why you’re doing something to a folder (other than the Fonts folder) in your Home/Library, don’t do it. There must be some good reasons why Apple decided to hide the Home/Library folder in OS X Yosemite, and one of them is to keep you from accidentally screwing something up.
