update mavericks to high sierra

I want to upgrade my MacBook Pro (Retina 2014) running Mavericks OS to High Sierra. I understand I must first update to Yosemite, but I do not see it as available at this time. I have a lot of business data backed up on an external Drive via Time Machine so I want to be sure to do this properly in order to transfer it over to my machine after installing High Sierra.

MacBook Pro (Retina, 15-inch, Mid 2014), OS X Mavericks (10.9.5), iTunes 12.6.2.20

Here is a better Apple web page that lists the requirements more clearly

And as to your client data, you should be making a backup before attempting any major install. I always recommend 2 backups, using 2 different backup utilities, going to 2 different back devices, because "Murphy's Law" doesn't care if you have "Naughty or Nice" 🙂


Time Machine

SuperDuper (free for a full clone; which is what you want before an upgrade)

Carbon Copy Cloner (1 month fully enabled demo)

Applications -> Utilities -> Disk Utility -> Restore (where the source is your boot disk, and the destination is the backup disk)

Have you read:

Can your Mac use High Sierra?

High Sierra requires any of the following Mac models and versions of macOS

MacBook Pro models from mid 2010 or later - OS X Yosemite


Mine is a 2014 WITHOUT Yosemite. What am I missing? Are you saying their columnar/line list should not be interpreted as a matrix? Have you actually done an update yourself outside this matrix and were able to regain your data via Time Machine?


Sorry for the challenge when you are trying to be helpful, but I have too much at risk. I have client data which if lost will set me back years and a lot of $$.


Thanks for your patience wit me.
