macOS Resizing active window

[perper]

Hi, i was wondering if its possible in the Cocoa or CGWindow api to access the current window and resize/set bounds?

Use the -setFrame: method and related methods on NSWindow.

(this only works if the window is in your process)

but is there any way to resize/move a window that is not in the same process?

There is no more direct API because that would violate security constraints, which isolate processes from one another unless they agree to accept requests from other processes. That agreement takes the form of an AppleScript scripting dictionary. The dictionary describes those things that other processes can manipulate. Things not in the dictionary can't be externally manipulated. There may be exceptions to this in some cases, but it is the general guiding principle.
