Epsilon https://www.lugaru.com/ https://www.lugaru.com/ Comes sufficiently close to be worth testing the free trial. I don't know the file size limit, but it handles multi-GB files. Does not fulfil the hex requirement. Recognizes and edits binary files but is not a hex editor. The previously suggested https://hexfiend.com/ https://hexfiend.com/ looks better for that. Unlimited line length, and can either horizontally scroll long lines or wrap them for display purposes. Fast regex. Unlimited undo/redo, including search/replace.
