How backwards compatible is OmniGraffle and how much can I ignore upgrades?
Like if everyone else on a group project is on a newer version, will I have to constantly bug people for older versions?
Also, what are the minimum mac requirements?
Basically I don’t want to have to buy a mac just to use OmniGraffle, but if I do then I would like to not spend too much money.
I don’t think the file format has changed for a while. I have used since early 7 series and no file changes noted; almost all the upgrades are for functionality as far as I know. Kind of where new features are hitting a bit of a road block in terms of maintaining compatibility. Maybe when they go to version 8?
For requirements, you can check the App Store and https://www.omnigroup.com/omnigraffle.
