How do I upgrade from OS X 10.6.8 to 10.11 or higher?
Lame question, I suspect. I have lightly refurbished my partnerʻs A1342, except for the HD, which will be replaced with a 1TB SSD (I know the SATA 3.0 is overkill, but it is downwardly compatible, so Iʻm OK with that).
Installed full 8GB RAM, a new display, fan, speakers, battery, and trackpad. Logic board, keyboard, and optical drive still perfectly functional. She wants to pass it on to one of the grandchildren, but OS X 10.6.8 is simply not going to cut it for their needs.
How can I get 10.11.6 installed on the current drive and on a subsequent SSD upgrade (I want to make sure the A1342 wonʻt get excessively overloaded by OS demands)?
