Preparing To Upgrade My Mac Os

What is the highest Mac OS that Sibelius version 7.1.3 can run on? 10.10(Yosemite) or El Capitan?

I currently have 10.8.5

Thanks!

Here you have some information.

I use Finale, and there were problems with El Capitán. Finally they were solved, but it took about 3 months. Meanwhile, I had to work with a backup (with Yosemite) I had in an external drive.

Thanks for the info, Luis. I am trying to get Yosemite, but the app store doesn't carry it anymore, and Apple is not being all that helpful. I'll probably upgrade to El Capitan but then it will cost more money because Sibelius and my DAW will have to be upgraded too. I don't enjoy this, but I guess we all have to do it sooner or later.
