Question: Update OS 10.9.5 to High Sierra

I have a Mac Mini, Late 2012, using OS X version 10.9.5, which must be upgraded to 10.11 or later in order to run TurboTax 2017. When i request software update from the Apple bar — it recommends High Sierra 10.13.3 and directs me to the APP Store. The Macintosh HD has 464 GB available. While it appears my computer meets the specified requirements, the recommended High Sierra will not download. The APP Store pops up — "macos High Sierra failed to download — Use the Purchases page to try again.” i have tried this many times to no avail.

your help will be appreciated.

That point applies to 10.7, but not 10.8 or newer. rcjg58 won’t be able to get El Capitan unless they already did or have access to an older Mac.

If someone’s using a configuration where it applies, they’ll be told so explicitly instead of getting an unrelated error message during the process.

As an aside what would people upgrade to if they had an option? My 2012 Mini is still on 10.9.5 (don't ask!) but has recently starting behaving in a rather buggy manner - very little use since purchased in 2014 when the 'new' Minis were announced but I need it now having killed off my 2015 MBP.

IF your 'Mac Mini Late 2012' computer - most shipped with Mavericks 10.9.x and won't run

newer version third-party software, then an upgrade to El Capitan 10.11.6 should do nicely.

Or further upgrade ~ if you have read about the issues; make suitable precautionary backups

and then hope you get lucky with High Sierra. At least you may be able to revert w/ backups.

Last Sept 2017 finally I chose to upgrade from Mavericks 10.9.5 to El Capitan 10.11.6 and

made a partition on original 1-TB HDD for second OS X install. It works OK. So it has two

OS X and dual-boots. And have 2nd internal HDD, in this server model, for other uses.

You have options because there still a link to get Sierra 10.12 from an App Store page.

{Reading though I've noted some Late 2012 Mac mini i5 and i7 users have issue with macOS

10.13.x High Sierra due to some graphics problem and some other performance complaints.

The graphics is built-in, and noticed El Capitan gives the GPU a higher output resolution, with

the same chip-set. I've used the same display; w/ max upgraded standard RAM before OS X.}

So you could test the waters 'one foot at a time' least there be swamping due to an under-tow.
