### Operating system:
Sæterprosjekt requires a 64 bit operating system. It uses [Unix epoch timestamps](https://en.wikipedia.org/wiki/Unix_time) (in milliseconds) in order to calculate time differences, and those values are too large for 32 bit operations (you could technically work a hack to seperate and store them in two 32 bit allocations but that would open another can of worms).
You can run the program in the following environments:
* Windows 7,8,10
* Linux
* Intel based Mac OSX (version 10.12 or higher). M1 silicon is not natively supported yet
### Multi user (network) environments
The program is not intended to be used by multiple users simultainiously. It will technically work, but because there's not coded routines (yet) in the program for IO locking operations, you risk to loose your data if more than one person edits the same record at the same time.
