I only have the one keyboard - given it works OK as I log in makes me think there is an odd setting been applied. I haven't tried safe mode so I can give this a go. Anything I should do once in safe mode?
Please let me know if that didn't work, so we can continue troubleshooting. Don't Rate my answer until you are satisfied.
Thanks - that works. What does turning it on provide? I have had an enthusiastic visitor who I have discovered has been experimenting with the settings which looks like the main source of my issues. I may find other odd things so is there any guidance as how to set system preferences (hopefully its just the universal access that has been altered and now changed back)?
Thanks - and is there any guidance available on best settings for system preferences? (I've learnt more about my mac over the last day that I have since I bought it 4 years ago). Thanks again for your help - let me know about any guidance and then I'll rate your excellent service.
