Hi there! Sorry to hear you're having trouble logging in to the MAC.BID app with your email, [email protected]. Let’s work through this together.

First, just to clarify a couple of things:

1. Are you entering your email and password exactly as registered? Sometimes a small typo can cause login errors.
2. Have you recently reset your password or changed any account details?
3. Are you seeing any specific error messages besides "Error in log in"? For example, something about incorrect password, account locked, or network issues?

While you check that, here are some quick steps to try:

1. Make sure your internet connection on your Mac running OS X 10.15.7 is stable.
2. Quit the MAC.BID app fully (Command + Q), then reopen it and attempt to log in again.
3. If possible, try logging into MAC.BID on a web browser to see if the issue is with the app or your account specifically.
4. If you suspect the password might be an issue, try using the "Forgot password" option to reset it securely.

Could you please try these and let me know what happens? If it still doesn't work, we can get into some more detailed troubleshooting steps!
