System Requirements

System Requirements

Mac: Accordance 10 and 11 run natively on Mac OS 10.6 and above (Snow Leopard to Yosemite). The App Store version of Accordance 11 requires OS 10.8.5 and above.

Windows: XP and above (including Vista and Windows 7 and 8).

Access to internet is required to download and validate modules, but not during normal use of the program. Any reasonably new computer is large enough and fast enough to run Accordance well.

For older Macs: Accordance 9 comes in two versions: a Universal Binary version for Intel or PowerPC with OS 10.4 or above and a 68K version for Classic systems including 10.1-10.3.


Why Macintosh?

OakTree Software, Inc. is committed to producing software of the highest quality, software which offers unparalleled power and ease of use. We develop for the Macintosh because doing so enables us to make the most efficient use of our resources. The Mac is widely known for its ease of use, integration of hardware and software, and relative lack of support-related issues. These and other qualities make it easy for us to focus on developing Accordance into the most advanced Bible study program available.


Why Windows?

We decided to develop Accordance 10 and 11 for the Windows market when it became technically feasible to do so from the same core code. This means that our Windows users now enjoy the same speed and power, and gain the same new features, as our Mac users. They can run the same modules, and transfer their user content between Mac and PC. Only the interface has been slightly adjusted to conform to the Windows experience.


What About Mobiles?

Accordance is available in the iTunes AppStore for the iOS, and runs on iOS 7 and 8 for iPhones, iPads, and iPod Touch. There is currently no app available for the Android platform. Mobile tablets that run true Windows systems (not Windows RT) do support the Windows version of Accordance.
