Question: My kid likes to listen to music on her iPad, but she can't read yet (she's working on it) so she has to play each song for a few seconds to find the song to which she wants to listen. Is there a way to enable VoiceOver for just the Music app? Enabling it for the entire device is annoying. Or is there an alternate way to play music that will speak the song titles?

Answer: 
Are you on a VPN of any sort (like a work network)? 

This error warns you of a Man in the Middle Attack (MITM). This means that there is potentially someone sitting between you and the website (main.yahoo.com) and trying to intercept the back and forth communication. Chrome thinks this because mail.yahoo.com uses `https` and `https` sites are supposed to provide a certificate. In this case Chrome thinks the certificate that it gets is not a good certificate (That's why `CERT_AUTHORITY_INVALID`). 

This happens if there is a really someone spoofing the network or if you are on a VPM of some sort like a work network. Some work networks use a self signed certificates that Chrome generally does not like. Some anti virus, firewall or other kind of network software may also cause this.

The most common cause of this issue is an incorrect date & time set on your PC. Chrome makes sure that your computer's clock matches the clock in a Google server farm, and if it doesn't, will block the connection to HTTPS sites for security reasons. 

**To fix your issue, set your computer's clock to the correct current time.** 

1. Go to System Preferences
2. Choose Date & Time
3. Navigate to the Date & Time tab
4. Change the current time to the correct time (accurate to the nearest minute will do).

**Edit:** If it's not your computer's fault, it's just a Chrome security feature. Chrome detects malicious activity going on with the site (like malware-laced ads, breach by hackers, etc.) and automatically warns you to protect you if it believes your security or safety might be at risk. If you want to override the warning, just hit `Advanced` -> `Continue to site`.
