However, what occurs when this F3 button suddenly ceases its functionality? Fear not, for the following paragraphs will enlighten you on a plethora of common remedies for this predicament.

If F3 does not lead you to “Mission Control,” there are multiple potential solutions to resolve the issue.
1. Reboot the computer
If you’ve ever worked as a tech assistant, you’re well aware that the ultimate remedy for any issue is to give the computer a fresh start. Occasionally, when encountering a system error or awaiting an update, a mere restart can work wonders. To initiate a restart on your Mac, simply click on the Apple icon positioned at the top left corner and select the option “Restart.”
2. Use “System Preferences” to modify your keyboard configurations.
Should restarting fail to yield results, consider modifying your keyboard settings. Simply click on the Apple icon and select “System Preferences.” Among the array of options presented, opt for “Keyboard.”
When the dialog window pops up, keep an eye out for the phrase “Utilize F1, F2, etc. Keys as regular function keys….” Right beside it, you’ll find a checkbox that can be marked or unmarked. Give it a try by marking (or unmarking) this box and then closing the window.
When the option “Enable standard function keys using F1, F2, etc. Keys…” Is activated (with the box checked), you will gain the ability to effortlessly utilize the conventional F3 function either by pressing the designated key or by simultaneously pressing the “fn” button located at the lower end of your keyboard.
3. Utilize “System Preferences” to modify your modifier keys.
One can explore an alternative approach to resolve the issue with the F3 key by utilizing the “System Preferences” feature. Simply tap on the Apple icon, select “System Preferences,” locate the option or icon corresponding to the “Keyboard,” and within the ensuing dialogue box, keep an eye out for a distinctive button named “Modifier Keys.”
By pressing this button, a captivating dialog window will emerge, unveiling a mesmerizing array of keyboard key functions. Delve into the dropdown list to ascertain if your “fn” key is presently engaged in another captivating task. Select the illustrious “fn function” from the list or simply grace the “Restore defaults.” Button with a click.
4. Restart the System Management Controller (SMC) for
If these common solutions using System Preferences and Keyboard Settings do not work, there are various other alternatives you can attempt.
The system management controller (SMC) is the mastermind behind an array of system operations, encompassing thermal regulation, battery charging, sleep/wake functionality, and keyboard controls. Resetting the SMC of your computer varies slightly depending on the Mac model you possess, as certain Macs employ a distinct internal chip dedicated to safeguarding sensitive tasks, such as touch sensor operations (like keyboards) or password-related activities.
If you are using a Mac equipped with the new M1 chip, you won’t find the SMC, so a simple restart would do the trick. However, for Macs with a T2 chip like Macbook Pro or Macbook Air, you need to get a bit more creative. Hold down the right Shift key, the left Option key, and the left Control key simultaneously for a minimum of seven seconds. After that, press and hold the power button for another seven seconds to restart the computer. As for older computers with a T1 chip, you’ll need to press and hold the Shift, Option, and Control keys on the left side, and then press the power button while holding down all of these keys for a solid ten seconds during startup. By resetting the SMC using these methods, you might just find that your precious F3 key is restored.
5. Reset the NVRAM on your computer
NVRAM, a fascinating segment of your computer’s memory, serves as a sanctuary for crucial fragments of information regarding the inner workings of your beloved machine. It holds the secrets of your startup disk and screen resolution, among other intriguing details. Should your keyboard’s functionality falter, fear not! A rejuvenation of NVRAM might just be the solution you seek. To embark on this mystical journey, bid farewell to your computer and prepare for a grand restart. As the machine awakens, grasp firmly onto the keys of power – Command, Option, P, and R – and hold them steadfast for a duration of no less than twenty seconds. If your trusty MAC possesses the charm of an audible chime at startup, be prepared to hear a second enchanting melody before you release the keys and allow the magic to unfold, bringing forth a normal booting process. With this enchanting remedy, the vexing F3 problem may soon become a distant memory.
6. Use a terminal program to run the command “killall dock”
In case the F3 key remains unresponsive, one may consider exploring a terminal program and executing the command “dillall dock.” This particular command effectively reboots the computer’s application “dock” situated at the bottom of the screen, thus reinstating the default settings. Typically, the dock houses various applications, including the “Mission Control” app linked to the F3 key, hence rebooting the dock might potentially restore its functionality.
What is a function key?
Similar to personal computers, the majority of Macintosh computers feature a series of keys positioned at the top of the keyboard, labeled F1 to F12. However, unlike their PC counterparts, Macs assign specific functions to these keys, such as adjusting volume or brightness. In certain Mac laptops, a compact touch strip has replaced this section. To access the conventional function keys, one can simply press the “fn” button located at the lower part of the Mac keyboard.
