"It’s at the finish line," Sarah, the junior dev, whispered from over his shoulder. With this option enabled, the process is clear:

: Only if you just installed a trusted plugin or manually edited your userSetup file.

"That’s a tiny difference," Elias argued, though his confidence was wavering. "Probably just a bit flip? A version mismatch? If we restart the setup, we lose the morning window. Let's just patch it later." If you'd like, I can help you: Locate

Even after setup is complete, Maya Secure periodically re-verifies critical checksums (e.g., during every authentication attempt or every 24 hours). This protects against delayed-action malware.
