My question is – is it possible/advisable, given the throat-slashing scenario described below?

1 Current OS: Sierra 10.12.2 2 Clicking comedy “update” button in “about” pane leads to “no app updates available” 3 I have no Apple ID/account, and cannot get one, because Thailand (I’ve tried -it’s beyond me) 4 I have found no help on-line as to which OS I can theoretically upgrade to, nor how 5 Safari is broken after an attempted update when it became truculent, cannot find any way to fix 6 Getting a Mac “Genius” to update would mean getting it sent to Bangkok and not seeing it for weeks, and then possibly with all my data erased, do not have the extra Mac box to back up my stuff, but do have several external HDs

Nothing (apart from Safari, which is a real pain) is broken. Should I be worrying myself (or anyone) about this yet? When my Mac eventually falls over, I won’t be able to afford another, so it’ll mean starting over with a *gulp* PC, for the first time in my life. Not looking forward to any of these possible futures.

In a private email, Hawkfall confesses to “not having the confidence” to start this long-overdue thread “in spite of my Mastermind Special Subject knowledge.” In the hope that he’ll join in the fun, then, let’s get some sand on our Mivvis and relive those wonderful years of sunny fun times!

(I should point out that I’m doing this as a favour. I haven’t watched the YouTube clip, from Hawkfall’s private collection, so caveat emptor.)
