CrossOver has been and is being translated into many languages. This means it is possible to have it display in another language depending on the MacOS settings.
If CrossOver is displaying a language you would not expect, close CrossOver and verify your settings:
Go to System Preferences
Under 'Personal' select 'International'
Verify that the language you would expect is listed first
If not, click and hold the language you would expect and drag it to a higher priority
Close the 'International' window
Launch CrossOver and verify your changes were made.
Please note that Crossover respects the "English" setting but not "British English", "American English", etc. "English" must be the top-most system language, or the secondary language beneath a specific type of English, in order to Crossover to display in English.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
