How to update your USB-C to MagSafe 3 cable

If your MacBook only chargers with USB-C, or uses an older MagSafe standard (2015 or earlier), this update won’t apply. Keep in mind, this applies to the MagSafe 3 cable that works with the recent MacBook Pros and MacBook Air. Unless someone was hacking MacBooks through the MagSafe cable, I doubt that’s the reason for this perplexing update. We know, for example, that iOS 16.3.1 and macOS 13.2.1 exist chiefly to patch zero-day security vulnerabilities that actively put your devices at risk. Unlike other updates, Apple never officially acknowledged this one’s existence, so there are no release notes detailing the reason for the patch. Perhaps charging is now more efficient? Maybe the charging indicator is now more reliable? It could be Apple is actively messing with us, and updated the cable simply because they can. This update is specifically for the USB-C to MagSafe 3 cable. Why did you issue a firmware update for a cable? It’s not even for the power adapter, either. Update your settings here to see it.Īpple, you have some explaining to do.
