Hi
Thanks for all your replies.
All sorted. What peeps weren’t including in their kind suggestions was that there are two ABSOLUTE MUSTS besides using Safari.
One: delete any files that might inc High Sierra
Two: Use ethernet connection and disable wifi.
Perhaps those kind enough to reply to my previous expected me to know that already, but sadly I did not.
I’m loading High Sierra as I type this and so far (knock on wood) it’s working!
probably have to Home install some more RAM though as some have said it can slow things down.
oh yeah and being an insomniac I did a lot of searching last night and took the general advice that it’s not a great idea to use any free download links like the one I was enquiring about.
This really occurred because after receiving an iPad for Christmas back in ‘17 I just stopped using the MacBook so fell out of the habit of doing upgrades. So lucky this forum exists and there are so many gracious and helpful members.
Namaste
ps thanks ‘leroydouglas’ I’m in Oz but am taking your advice and buying a 2015 13” MacBook Pro. They run about $700-$900 aussie for an as new 8 gig running Catalina. My only hesitation is wether the whole used Mac market will take a big hit when Apple Silicon rolls out? I’ll make a thread 😅
