Sep 29, 2015 Tip. If you want to find a given value in a range, column or row, select that range, column(s) or row(s) before opening Find and Replace in Excel. For example, to limit your search to a specific column, select that column first, and then open the Find and Replace dialog. The first release of the new OS — Mac OS X Server 1.0 — used a modified version of the Mac OS GUI, but all client versions starting with Mac OS X Developer Preview 3 used a new theme known as Aqua. Aqua was a substantial departure from the Mac OS 9 interface, which had evolved with little change from that of the original Macintosh operating. FileVault is available on all new MacOS and Mac OS X versions and Mac computers. For some history, FileVault debuted in Mac OS X 10.3, and the earlier versions of FileVault actually only locked down and encrypted the user home directory, whereas modern versions of FileVault encrypt the entire hard drive and all data. The term Mac OS stands for Macintosh Operating System. It’s a UNIX based operating system by Apple, exclusively for MacBooks and iMacs. In the market of Desktops, Laptops, and Home Computers it’s the second most widely used desktop OS after Windows. Apple's macOS, a replacement for Apple's earlier (non-Unix) Mac OS, is a hybrid kernel -based BSD variant derived from NeXTSTEP, Mach, and FreeBSD. Unix interoperability was sought by establishing the POSIX standard.
Control features on your Mac
By default, the top row of keys on your Apple keyboard control many different features on your Mac. For example, pressing the keys with speaker icons adjusts the volume.

Use standard function keys
Mac Os Mojave
Standard function keys work differently depending on the app and the keyboard shortcuts that you've set up. Some apps have their own keyboard shortcut preferences that you can customize.
To use the standard function keys, hold the Function (Fn)/Globe key when pressing a function key. For example, pressing both Fn and F12 (speaker icon) performs the action assigned to the F12 key instead of raising the volume of your speakers.
Mac Os Catalina
If your keyboard doesn’t have an Fn key, try pressing and holding the Control key when pressing a function key.
Change the default function key behavior
If you want to change the top row of keys to work as standard function keys without holding the Fn key, follow these steps:
- Choose Apple menu > System Preferences.
- Click Keyboard.
- Select 'Use F1, F2, etc. keys as standard function keys'.
If you don't see 'Use F1, F2, etc. keys as standard function keys'
If you don't see 'Use F1, F2, etc. keys as standard function keys', you might be using a keyboard not made by Apple. These keyboards might need a utility to change the keyboard functions. Check with your keyboard manufacturer for more information.
