10.12 breaks the function keys

Can support is no longer on < FN > 10 or < FN > 11 to get to the office with all the hidden windows.

Cannot see the open windows tiled on F3 or < FN > F3 etc. that is printed on the keyboard.

It worked for (let's see now...) a dozen years...

10,12 macOS Sierra broke which is an essential part of any user to be able to work.

Needs to be repaired.  Quick.

See if that fixes the problem:

Install OS X from scratch

Backup if possible before proceeding.

  1. Restart the computer. Immediately after the chime hold down the command and R buttons until the Apple logo appears. When the Utility Menu appears:
  2. Select utility disc in the Menu Utility, then click the continue button.
  3. When loading disk utility, select the volume (entered into withdrawal, usually Macintosh HD) from the list of devices.
  4. Click Delete in the main window of disk utility. A panel will fall.
  5. Define the type of Format Mac OS extended (journaled).
  6. Click on the apply button, then wait for the done button to activate and click on it.
  7. Quit disk utility and re-enter the Utility Menu.
  8. Select reinstall OS X and click on the continue button.

  • HP Envy 17: Reverse the function keys

    Hey guys,.

    My laptop is a very good laptop, with a good graphics card nvidia an i7 cpu and even 16 GB of ram. Even with a 17 inch screen full HD 1920 * 1080, making incredible games! Even GTA V for Pc works quite well on this laptop powerful.

    All of these things are an amazing gaming PC, however, it has a match no one back which makes it almost impossible to play a game with good fluidity.

    Present a defect of fatal game is actually the keyboard, but to be more precise, it is the function keys. The HP Envy 17 has two F1 - F12 and INSERT key. However, these are the secondary keys. Primary keys are keys system that changes the brightness or volume. That means if I want to use F2 in a game, I have to hold the function key, and then press F2.

    This seems minor, but when you play, it can be annoying to have to hold down a function key just to use one of the F keys.

    Dies, does anyone know how to get this fixed and reverse the trend, in this way if I want to cut my cell phone that I have to press the function, then the F6 key. I hope that people know what I mean and please if you know of a fix would be great if you could post it below.

    Thank you

    Hello

    Yes, I used the F1 - F12 keys on a daily basis for the last 35 years or so, but fortunately I always use external keyboards using laptops (on or off a docking station). You may not share, but disable. Please use the following article:

  • Re: How to change its use of the function keys?

    The function keys on my laptop P870 are keys to double action. You must press the FN key at the same time as the key function F1, F2. In particular, I use the F2 key a lot but have to use 2 hands (unless you have extremely long fingers) to operate the function keys driving me crazy.

    Any suggestions?

    Change of cell function special mode reboot and test how it works.

    Thank you
    Mike

    Hello

    In my opinion one of the important gift of drivers or utilities work and, therefore, you cannot use the FN keys.

    If your have installed XP on your test of the G20 to refresh the Toshiba common Modules.
    It is an essential tool that controls the FN keys.

    The common Modules can be downloaded from the page of European driver of Toshiba.

    Check it out.

  • Is there a documentation about the configuration of the function keys (program)

    Is there a documentation about the configuration of the function keys (program).

    Dell Dimension 1400, model XP SK8110 keyboard.   Yes, I know there are 7 years old, but running like a champ.

    Hello

    You can use various function keys to activate certain features and commands only. The following list details the current functions keys, what they do, and when you can use them.

    Three keys can be used when Setup is loading and when you are prompted to press the F6 function key to install some third-party small computer system interface () SCSI and host controller drivers:

    • F5 - for computer type or hardware abstraction layer (HAL) selection
    • F6 - to install the SCSI controller drivers and third-party host
    • F7 - to run Setup without Advanced Configuration and Power Interface (ACPI)

    When the "Welcome" screen is displayed, the following function keys can be used:

    • F2 - to automatically start the process (ASR, Automated System Recovery).
    • F10 - to bypass the menu screens and to load the Recovery Console

    During the GUI (GUI) - Mode Setup, the following function keys can be used:

    • SHIFT + F10 - to enable access to a prompt during the installation in graphical Mode
    • SHIFT + F11 - to display "old" wizards that give more detail.

    Thus, it is not possible to configure the function keys to perform this task. However, you can use your favorite search engine to perform this task.

    Warning: Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.
