No apologies necessary alto, I feel your pain. Been there, worn the T-shirt.
Shame it's Apple. If it were MS or Linux, I could maybe help (or rather my personal sys admin could help)
For others, I run Linux - Arch Linux to be specific. But any of the Ubuntu/Linux/KDE OS are great, and you're bound to find a distribution to suit your needs/expertise/lack of expertise and your hardware. No matter how old or how small, there's a Distro that will help
By the way, I'm still looking for the LC tank, will tag you if I find it
