The MacOS analog of .exe is .app. The installer package is .dmg for Mac.

Please ignore the other info here, you can log into several accounts on gmail without any other work in the browser or having to create multiple profiles or any of that, since Google supports this with gmail

But just in case you can/want "merge" info and don't care about user identification on multiple accounts.
