Expecting value line 1 column 1 (char 0) or “Error While Installing” pop-up on Mac is a message that may appear in the form of pop-up on your macOS and could be caused by unwanted software or even malware, trying to modify certain aspects of your Mac. Not just this, but also be advised that these pop-ups could be caused by a nasty Trojan, that may aim to steal certain information from your Mac, like your passwords or download other viruses on your device.
