I fear there is nothing that can be done with what I've managed to do with my Mac Mini.
I have a Mac Mini that is running OS X Lion. I'm a complete newbie to Macs although I am an experienced PC user.
Quite how I've managed to do this I honestly don't know and if it's any consolation I'm really p****d with myself but, in the process of loading a new keyboard layout for UK keyboards (it was driving me nuts that the @ symbol was swapped with the " symbol) I've managed to completely delete all the native keyboard layouts that were in a .bundle file. Although the custom UK layout remains and it works if you type within Mac Office Word 2011, it does not work elsewhere. All that remains of supported keyboards are various Chinese, Korean, Tamil and Vietnamese layouts!
So, why not 'obtain' the missing file and load it? Quite how I can get hold of it I don't know but that's not really the biggest issue...the problem is that each time I try and do anything in the system I'm asked for a password. I know the password....God knows I know the password!!...but I'm unable to type it in because I have no keyboard layouts that are recognised!
I fear I've backed myself into a corner and there's nothing I can do. I can't load BootCamp to get Windows installed on the drive because I need to be able to type; I can't install any other keyboard layouts because I need to be able to input the password...and so on and so forth. Oh, and the system will not let me type the password into Word and then copy and paste it into the dialogue box - the usual shortcut keys do not work and right-clicking doesn't bring up a menu so here I am going round and round in ever decreasing circles until I disappear....well you know where I'm headed!!! :)
So folks, have you got any magic beans that you can spare? I'd be everso pleased to hear from you if you can offer any form of solution....no matter how convoluted!
