Where Is the Option Key on Apple Keyboards?

The Option key on Apple keyboards is located between the Control key and the Command key, on both the left and right sides of the space bar. It is labeled “Option� on most models, and also shows the symbol “⌥�. On Mac notebooks, the left Option key sits directly to the left of the space bar; on desktop keyboards, the same layout applies.

Background: How the Option Key Got Its Name

The Option key has been part of Apple keyboards since the 1980s, originally introduced on the Apple Lisa and later the Macintosh. Its name reflects its primary purpose: to provide alternative characters and alternative functions. Unlike the Shift key, which mainly changes letter case and symbol access, the Option key unlocks a whole layer of additional characters (like ©, ™, and €) and modifies menu commands, such as Option+Click to close all windows or Option+Volume to adjust sound in smaller steps.

On older Apple keyboards (pre-2007), the key was labeled solely with the ⌥ symbol and the word “option.� In 2007, Apple began printing “alt� on the key as well, to align with PC users who were switching to Mac. The key still functions identically to the PC’s Alt key in many contexts, but it also has Mac-specific uses. This dual labeling can confuse new users, but the physical position has remained constant for decades.

How the Option Key Works on Mac

The Option key is a modifier key, meaning it changes the behavior of other keys or clicks when held down. Here are the most common functions:

• Typing special characters: Hold Option and press a letter or number to type symbols like Option+2 = â„¢, Option+3 = £, Option+4 = ¢, Option+5 = âˆ�, and Option+8 = •. The exact characters depend on your keyboard layout (e.g., US vs. UK).
• Menu shortcuts: Many menu items change when you hold Option. For example, in Finder, holding Option turns “About This Macâ€� into “System Information,â€� and turns “Copyâ€� into “Copy as Pathname.â€�
• Clicking shortcuts: Option+Click on the red close button closes all windows of an app. Option+Click on the Wi-Fi icon shows detailed network information. Option+Click on the volume icon lets you choose input/output devices.
• Boot options (on Intel Macs): Holding Option at startup opens the Startup Manager, letting you choose a different boot drive. On Apple Silicon Macs, the power button serves this role, but Option still works in some recovery contexts.

On a Windows keyboard connected to a Mac, the Windows key maps to Command and the Alt key maps to Option. That means the physical key labeled “Alt� on a PC keyboard will function as Option when used with macOS.

How to Choose the Right Option Key for Your Needs

If you are buying a replacement keyboard or a new Mac, consider these factors:

• Keyboard layout: Apple keyboards come in US, UK, and various international layouts. The Option key is always in the same position relative to the space bar, but the labels and symbols on other keys may differ. For example, UK keyboards have a “£â€� on the 3 key, which you type with Option+3.
• Notebook vs. desktop: MacBook keyboards have a slightly smaller Option key to fit the compact layout, but it is still the second key from the left on the bottom row. Desktop keyboards (Magic Keyboard) have full-size keys with the same spacing.
• Wireless vs. wired: The Magic Keyboard (wireless) and the older wired Apple Keyboard both have identical Option key placement. If you use a third-party keyboard, check that it has a Windows/Alt key that can be remapped, or look for a Mac-specific version.
• Accessibility: If you have limited hand mobility, you can use macOS’s Sticky Keys (System Settings > Accessibility > Keyboard) to press Option once and have it stay active until you press another key. You can also remap the Option key to act as Command or Control via System Settings > Keyboard > Modifier Keys.

Common Problems and Fixes with the Option Key

Users occasionally report that the Option key doesn’t work as expected. Here are the most common issues and their solutions:

• Key not responding at all: Check for debris or liquid damage. If the key is physically stuck, gently clean around it with compressed air. If it still fails, it may be a hardware issue that requires service.
• Option key acts as Control or Command: This happens if the modifier keys have been remapped. Go to System Settings > Keyboard > Keyboard Shortcuts > Modifier Keys and set Option to “Option.â€�
• Option key works but types wrong characters: Your keyboard layout may be set to a different region. Go to System Settings > Keyboard > Input Sources and ensure the correct layout is selected (e.g., “ABCâ€� or “U.S.â€�).
• Option key not working in a specific app: Some applications (especially games and remote desktop tools) may ignore the Option key or require you to enable “Use all F1, F2, etc. keys as standard function keysâ€� in System Settings > Keyboard. For remote desktop, check the app’s settings for modifier key mapping.
• Option key on a Windows keyboard: If you’re using a PC keyboard with a Mac, the Alt key should work as Option. If it doesn’t, install a key remapping tool or use the built-in modifier key settings to swap Alt and Command if needed.

Option Key vs. Alt Key: What’s the Difference?

On a Mac, the Option key is often labeled “alt� as well, but it is not identical to the Alt key on a Windows PC. In Windows, Alt is used to access menu bars and shortcuts like Alt+F4 (close window). On a Mac, the Option key provides alternative characters and modifies commands, but it does not trigger the Windows-style menu access. When you run Windows on a Mac (via Boot Camp or a virtual machine), the Option key behaves as the Alt key, so Alt+F4 works. In macOS, the equivalent to Alt+F4 is Command+Q (quit app) or Command+W (close window).

Another difference: the Option key on a Mac is more like the AltGr key on some international PC keyboards, because it gives access to a third layer of characters. For example, on a US Mac keyboard, Option+e followed by a vowel creates an accented character (é, ñ, etc.), which is similar to how AltGr works on European keyboards.

Alternatives to the Option Key

If you don’t have an Option key (e.g., using a keyboard without one), you can still access most of its functions:

• Use the on-screen keyboard: Go to System Settings > Accessibility > Keyboard and enable “Show Keyboard and Character Viewer in menu bar.â€� The Character Viewer lets you insert any special character without using the Option key.
• Remap another key: In System Settings > Keyboard > Modifier Keys, you can change the Caps Lock key to act as Option. This is a popular choice for users who want an extra Option key on the left side.
• Use keyboard shortcuts without Option: Many Option-based shortcuts have alternatives. For example, instead of Option+Click to close all windows, you can use Command+Option+W (which still requires Option). But you can often use the menu bar: hold Option and click the app name to see the hidden menu items, then click the command.
• Third-party keyboards: Many mechanical keyboards allow you to program any key to send the Option keycode. You can also use software like Karabiner-Elements (open source) to remap keys on any keyboard.

Frequently Asked Questions

Where is the Option key on a MacBook Pro?

On all MacBook Pro models, the Option key is the second key from the left on the bottom row, directly to the left of the Command key and to the right of the Control key. It is labeled “Option� with the ⌥ symbol. There is also an identical Option key on the right side of the space bar.

Why does my Option key show “alt� instead of “Option�?

Apple began labeling the key with both “Option� and “alt� in 2007 to help users transitioning from Windows. The key functions the same regardless of the label. If your keyboard only shows “alt,� it is likely a third-party keyboard designed for Windows, but it will still work as Option when connected to a Mac.

How do I type the Apple logo (?) with the Option key?

On a Mac, you can type the Apple logo character (?) by pressing Option+Shift+K. This works on most Mac keyboards and in most applications, though some fonts may not include the glyph. If it doesn’t appear, copy it from the Character Viewer (Edit > Emoji & Symbols).

Can I use the Option key to boot into Windows on a Mac?

On Intel Macs, holding the Option key at startup opens the Startup Manager, where you can select the Windows partition if Boot Camp is installed. On Apple Silicon Macs, press and hold the power button instead, then choose the startup disk. The Option key does not directly boot Windows on Apple Silicon Macs.

Why is my Option key acting like a Control key?

This usually means the modifier keys have been swapped in System Settings > Keyboard > Modifier Keys. Open that setting and check that “Option Key� is set to “Option.� If you’re using a third-party keyboard, its firmware may also remap keys; check its configuration software.

What is the symbol ⌥ on the Option key?

The ⌥ symbol is called the “option sign� and is used on Apple keyboards to denote the Option key. It resembles a diagonal line with a small vertical notch, and it is used in menus and documentation to indicate Option key shortcuts. The symbol is derived from the original Apple keyboard design and has no official meaning beyond representing the key.
