So, for the benefit of any tech enthusiasts and at the risk of chasing away everyone else, here is what the innards of my iMac looked like when I finally succeeded in the tooth-grindingly difficult operation of opening him up. The diagrams drawn by the Genius who kindly advised me at the Apple store were more or less useless, probably applying to a different Mac model altogether, but with patience, doggedness, brute force and a look at some tech videos on the internet, I managed to work it out and only lost one of the teeny weeny screws inside the patient. But since he's unlikely ever to recover I suppose it doesn't matter that he's got a loose screw somewhere in his electronic brain.
And here is my hard drive which I succeeded in removing for subsequent plugging into my laptop and copying the files therein.
That's the end of this techy saga, although having to abandon the use of software such as Dreamweaver for uploading my website is still a problem. I'm looking into other alternatives but meanwhile, attention to computer-language has brought out my philosophical, metaphor-seeking tendencies.
For instance: take one of the options under the History menu on the top bar of your browser screen (I assume your browser has some tabs up there? Mine has, whether I use Safari or Firefox or Chrome). One of the items in that menu is:
Isn't that wonderful? With one click we can clear our entire history and start anew, unburdened of our past mistakes and the mistakes anyone else made concerning us, free of all our procrastinations, self-defeating habits and repetitious behaviour. One click and it's all gone!
So all we have to do is to figure out what that metaphorical CLICK means in ordinary, real-life language. What is the trigger in our minds which could instantly set off the CLEARING HISTORY process?
And look at those tabs at the top of your browser again: they are all wonderful advice - think about it:
What more do you want?
