As a Mac user, you may have stumbled upon a key on your keyboard that seems mysterious and often goes unnoticed – the Eject key. Located in the top right corner of your keyboard, this key has been a part of Mac keyboards for decades, but its purpose and functionality have changed over time. In this article, we will delve into the history of the Eject key, its original purpose, and its current uses on modern Macs.
A Brief History of the Eject Key
The Eject key has its roots in the early days of personal computers, when floppy disks and CD-ROMs were the primary means of data storage and installation. The key was originally designed to eject the floppy disk or CD-ROM from the drive, allowing users to remove the media and insert a new one. This was a crucial function, as it prevented users from accidentally damaging the disk or drive.
As technology advanced and Macs began to adopt newer storage formats, such as DVDs and USB drives, the Eject key remained a staple on Mac keyboards. However, with the introduction of slot-loading optical drives in the late 1990s, the need to physically eject media became less necessary. Despite this, the Eject key persisted, and its functionality evolved to accommodate new uses.
The Original Purpose of the Eject Key
The primary function of the Eject key was to eject the media from the optical drive. This was achieved by pressing the key, which would trigger the drive to open and release the disk. The Eject key was also used in conjunction with other keys to perform additional functions, such as:
- Forcing a disk to eject: By holding down the Eject key and the mouse button, users could force a disk to eject, even if the drive was malfunctioning.
- Ejecting a stuck disk: If a disk became stuck in the drive, the Eject key could be used to try and dislodge it.
Using the Eject Key with Older Macs
If you’re using an older Mac with a built-in optical drive, the Eject key still functions as intended. You can use it to eject CDs, DVDs, and other media from the drive. However, it’s worth noting that many modern Macs no longer have built-in optical drives, making the Eject key’s original purpose less relevant.
The Eject Key on Modern Macs
So, what happens to the Eject key on modern Macs that no longer have optical drives? The answer lies in the key’s new functionality. On newer Macs, the Eject key has been repurposed to perform different actions, depending on the context.
- Ejecting external media: If you have an external USB drive or SD card connected to your Mac, the Eject key can be used to safely eject the media.
- Displaying the Notification Center: On Macs running macOS High Sierra or later, the Eject key can be used to display the Notification Center. This is a convenient way to quickly access your notifications and widgets.
- Customizing the Eject key: Using the Keyboard preferences in System Preferences, you can customize the Eject key to perform a different action, such as opening a specific app or triggering a keyboard shortcut.
Using the Eject Key with External Devices
When using the Eject key with external devices, it’s essential to understand the correct procedure to avoid data loss or corruption. Here’s a step-by-step guide:
- Connect your external device to your Mac.
- Ensure that the device is properly mounted and recognized by your Mac.
- When you’re finished using the device, press the Eject key to safely eject the media.
- Wait for the device to be fully ejected before disconnecting it from your Mac.
Alternative Uses for the Eject Key
While the Eject key’s primary function may have diminished, its versatility has increased. Many users have discovered alternative uses for the key, including:
- Assigning a custom keyboard shortcut: Using the Keyboard preferences, you can assign a custom keyboard shortcut to the Eject key, allowing you to perform a specific action or trigger a macro.
- Using the Eject key with third-party apps: Some third-party apps, such as those designed for video editing or audio production, may utilize the Eject key as a shortcut for specific functions.
Customizing the Eject Key with Keyboard Shortcuts
To customize the Eject key with a keyboard shortcut, follow these steps:
- Open System Preferences and select Keyboard.
- Click on the Shortcuts tab.
- Select the action you want to assign to the Eject key from the list on the left.
- Click on the Add Shortcut button.
- Press the Eject key to assign it to the selected action.
