My MacBook Air is suddenly possessed - help!!

[PacificDogwood]

It was all fine this morning.

Nobody has touched it all day.

Tonight it is no longer passcode protected, I cannot open some TIO due to a parental lock being in place, I have to 'click' the touchpad rather than just touch it to click anything, all my past history is gone (bookmarks etc).

It's all backed up on an AirPort, so I am not too worried about content.
But what on earth happened?
Apparently my firewall is switched off. I cannot reset it because I have no clue what my administrator username and password might be. It does not seem to be my Apple password.
To say I am is an understatement…

Can anybody shed any light on this??

I am off to bed hoping you lovely geeks are night owls

Please??

At the very least I have to figure out how to get the parental lock off - I cannot read a discussion about the morning after pill FFS!

I will have to speak to Apple, won't I?

Ha!

I figured it out all by myself
Now if only I could figure out how to stop talking to myself…

Well done!

Where were you when I needed you?!

I so need a 'MacBook for Dummies' kinda guide - any suggestions?
I know there is an actual 'MacBook for Dummies' but it gets very mixed reviews on Amazon, so I have not pressed the checkout button yet
Any recommendations?
I need an actual book I can have open next to the laptop, not an online 'help' - they make me despair!

Oh gawd! I'm in the same boat!! I'm about to buy one but I need the very same book! I've just posted for advice I have no idea about computers so feeling very nervous about spending all that money then only being able to admire how beautiful it is!! Good luck

It is beautiful, isn't it?
Maybe I should just keep it as a piece of sculpture on the mantlepiece…

You are not help! Really!! Outrageous!

I think I am going to keep bumping this thread until somebody knowledgable comes along...

Probably best sorreeeeee!!

mac basics for dummies,some of the stuff on there is very basic but it may help.

Oh, Chanatan, thank you, that looks good

I am so aware that I am using about 0.00001% of my lovely device's abilities…. I need help.
