Solved - Old Mavericks OS X 10.9.5 to High Sierra

[Francart]

Hi,

We have created a configuration with your recommandation and thanks for it to your site and we are very happy with it. But for reasons of compatibility and software update, we want to pass it on High Sierra. The version of OS X currently in use is Mavericks 10.9.5.

Mac Pro configuration
GIGABYTE GA-Z87X-UD5H
INTEL CORE I7-4770K 3.50GHZ
ASUS GTX770-DC2OC-2GD5
CRUCIAL 32GB KIT (8GBX4) DDR3 CL8 BAL. TACTICAL
SAMSUNG SSD 2.5" SERIE 840 EVO 500 GB

CORSAIR CARBIDE SERIES AIR 540
CORSAIR CX750 MODULAIRE 80+BRONZE
NOCTUA NH-U12S

What is the best way to get to the update of High Sierra. We can reinstall the SSD if needed.

Thank a lot for your help and thank you to exist.

Maxime

One more thing, I can't download, via Mac App Store, OS High Sierra. they tell that my config isn't compatible with this OS. Where could I find the install file to follow the installation procedure. Thank you,

You may need to change your system definition.
