This has to be the strangest problem I have ever encountered in my 20+ years of Apple software/hardware issues.


My MacBook Pro is unable to type a period only in Safari. I have no problem in any other app.


What I end up doing (as I am here) is type a perion in stickies and copy and past from there.

Very annoying!


If anyone has any idea what is causing this please let me know.

It is driving me nuts!

    Open the Finder. From the Finder menu bar click Go > Go to Folder


    Type or copy paste the following:




    Click Go then move the Cache.db file to the Trash.



    Quit and relaunch Safari to test.

    Please read this whole message before doing anything.


    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.


    Step 1


    The purpose of this step is to determine whether the problem is localized to your user account.


    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”


    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.


    Test while logged in as Guest. Same problem?


    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.


    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.


    Step 2


    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, or by corruption of certain system caches.


    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.


    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain models.  The next normal boot may also be somewhat slow.


    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.


    Test while in safe mode. Same problem?


    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

    It worked in the guest account (step 1) but did bit work in safe mode (step).

    From the Safari menu bar, select


    Safari Preferences Extensions


    Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.


    If you wish, you may be able to salvage the errant extension by uninstalling and reinstalling it. Its settings will revert to their defaults. If the extension still causes a problem, remove it permanently or refer to its developer for support.
