System Requirements

System Requirements

Mac: Accordance 12.1 and up runs natively on Mac OS X 10.7 and above (Lion to High Sierra). The App Store version of Accordance 11 requires OS X 10.8.5 and above. Versions 10, 11, and up to 12.0.6 also run on Mac OS X 10.6 (Snow Leopard).

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.

Windows: Accordance runs on many different versions of Windows. The full compatibility list includes Windows 10, 8 (including the Surface Pro and other tablets), Windows 7, and Windows Vista. Accordance 12 does not run on Windows XP. Older versions of Accordance may run on Windows XP, but XP is no longer supported by Microsoft. Accordance does NOT run on tablets with Windows RT nor on Windows 10-S.

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.


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?

Bible Study with Accordance (v. 2) is available in the iTunes AppStore for the iOS, and runs on iOS 8+ for iPhones, iPads, and iPod Touch. There is a new app in preparation for the Android platform. Mobile tablets that run true Windows systems (not Windows RT) do support the Windows version of Accordance.
