There are several places on your computer where you can install a keyboard layout. The main difference between them is who is able to see and use the keyboard layout. If you want the keyboard layout to be visible only to yourself and no other users on your computer, install it in the folder ~/Library/Keyboard Layouts where ~ means your home folder. In other words, this is a folder called “Keyboard Layouts” (which you can create if it doesn’t already exist) in the Library folder inside your home folder. If you want the keyboard layout to be used by any user of your computer, the folder to install is: /Library/Keyboard Layouts That is a folder called “Keyboard Layouts” in the Library folder at the top level of your startup disk. Again, you can create it if it doesn’t already exist. Finally, if your computer is used as a server for other Macs, you can put the keyboard layout in the folder: /Network/Library/Keyboard Layouts That is a folder called “Keyboard Layouts” inside a folder called “Library" inside the Network folder at the top level of your startup disk. Again, you can create these folders as needed. One final important word about installing a keyboard layout. The operating system scans these folders when you log in, and loads the keyboard layouts only if the folder has changed since you last logged in or the computer was restarted. Generally, this means that you can install your keyboard layout, log out, log in again, and the keyboard layout is available for use. The difficulty is when you modify an already installed keyboard layout. In this case, the keyboard layout file has been modified, but the folder has not changed, and so logging out and logging in again does not load the new version. In this case, what you should do is to drag the keyboard layout file out of the Keyboard Layouts folder, say to the desktop, and then drag it back in. This changes the folder, so that logging out and logging in again will load the new version. Next page Up to "Using a keyboard layout"
