2 mac OS questions

[Fifteen20s]

These may be basic questions, but one is a nuisance I have lived with and the second is a curiosity

1. How do you / can you open multiple calculators


2. Does "Clear History and Website Data" in the Safari tab completely remove that history / Data / Cookies, or is there another folder somewhere that should be cleared too?

1. Use the Dashboard.

2. It sends it covertly to the NSA. You're still screwed.
