•Operating System. Runs under the 64-bit versions of Windows 10 and 11. Prism 10 does not support 32-bit editions of Windows.

•CPU. x86-64 compatible. Note: Prism Windows is not currently offered in a version compiled to run natively on ARM chipsets (i.e. Qualcomm Snapdragon). However, Prism Windows can run on ARM-powered devices using x64 emulation which is now generally available with Windows 11

•RAM. For comfortable performance and responsiveness, Prism requires the following amount of RAM:

o2 GB RAM for up to 2 million data cells in currently open Prism files

o4 GB RAM for 2-8 million data cells

o8 GB RAM for 8-16 million data cells

o16 GB RAM for greater than 16 million cells

•Display. The minimum display resolution is 800 x 600, but the recommended display resolution for comfortable work is 1366 x 768.

•HDD. Requires about 100 MB (megabytes) of space on the hard drive.

•Internet. Prism must connect to the internet to verify the license when it is first activated. It will also attempt to connect upon every launch, and every 24 hours if the application is not closed. To continue operating, this connection must be successful once every 30 days (or 20 attempts, whichever comes sooner).

•Additional Information. Prism requires that the Microsoft Edge WebView2 rendering component be installed to correctly display pages in the Welcome Dialog. This is already installed by Microsoft on most new devices, but will be included with the Prism installation if it is missing.

Prism 10 for Mac

•Operating System. Runs under macOS X 10.15 (Catalina) or later. If you use macOS 10.14, Prism will launch and seems to run OK, but we haven’t tested Prism thoroughly under this version of macOS and can’t provide much support. If you use 10.14, we urge you to update macOS.

•RAM. There is no particular requirement for RAM on Mac. Prism will run fine on all standard configurations of Macs manufactured by Apple.

•Display. Requires a display with a resolution of at least 1024 x 768 pixels.

•HDD. Requires about  130 MB (megabytes) of space on the hard drive.
