Anything anyone can add to the previous discussion — to allay my trepidation and paranoia — would be gratefully received in anticipation of my upgrading to El Capitan tomorrow.
From all I've been given to understand, the process should go rather fluidly:
• Open the .dmg file in Applications and then, if necessary, run the Combo Update and Security Update.
• Update to current versions all third-party OS tools (such as Onyx and TinkerTool), as well as Firefox and Thunderbird.
• Pray that everything goes according to Hoyle (who, admittedly, never had a clue about the internet, but who is still the patron saint of the rule book).
Anything else?
Vis-Ã -vis Time Machine: I've been told to disconnect my TM hard drive prior to upgrading, then once everything has been installed and tweaked to reattach the hard drive and back up the changes.
Any specific recommendations in this regard?
And will Recovery HD be functional (and backed-up) by so doing?
