Hi there! It looks like you've encountered a security notification regarding a potential Man-in-the-Middle (MiTM) threat from HealthEquity. I understand that can be concerning. Let’s work through this together.

First, to clarify, a MiTM threat generally indicates that there could be unauthorized access between your device and the server, which means your connection may not be secure. Here are a few steps you can take to address this situation:

1. Check Your Internet Connection: Make sure you're connected to a secure network. Avoid using public Wi-Fi if possible.

2. Refresh Your Browser: Sometimes, these messages can be the result of temporary connection issues. Try refreshing your page or reopening your browser.

3. Update Your Software: Ensure that your Mac operating system is updated and that your web browser is the latest version. Go to Apple Menu > System Preferences > Software Update to check for macOS updates.

4. Clear Browser Cache: Sometimes, old data can cause warnings. You can clear the cache by going to your browser's preferences and finding the relevant option under privacy or history.

5. Scan for Malware: Run a security scan with an antivirus program to make sure your device is clean.
