rbx_cookie fails to find logged-in cookie on MacOS

[sasial-dev]

Describe the bug
rbx_cookie fails to find a cookie if mutiple users are logged into Roblox Studio on a mac. I'm not sure about windows.

To Reproduce
Steps to reproduce the behavior:

1. Log into two accounts in Roblox Studio
2. Try to get the cookie through the library

Expected behavior
It should default to the currently logged in user in studio or error?

Hey, thanks for raising. Can you provide more details on what exactly you're experiencing?

I didn't know it was possible to login to two accounts at once.

[sasial-dev]

Studio actually lets you log into mutiple accounts! (But i'm only logged into one atm)

But once I've done that, rbx_cookie just thinks I'm not logged in at all.
I'm not sure if this works on windows though, but it is an issue on my mac.

I'm actually failing to pick up the cookie with a single account now. When I run rbx_cookie --verbose I see a bunch of these warnings:

[2025-03-02T21:25:04Z WARN rbx_cookie::binarycookies] cookie parse failure: c string non null terminator

And no cookie is returned.
