Apple releases fix to safety flaw in Mac working system

Soon after the discovery of the vulnerability, an Apple representative told reporters MacRumors that the company is aware of the issue and is working on a software update to fix it.

For these users, the security update can be installed again (in fact, it would be automatically installed at some point) after updating to the new version of the operating system. With the bug in the operating system, any person or malicious program that tried to log into a Mac computer, or install software, or even change settings, could do that by simply entering root as username on the prompt, and they were able to bypass the prompt to gain full access to the computer. All Macs running High Sierra appeared to be affected.


You'd think that would be the end of Apple's software troubles for this week, but you'd be wrong.

Apple released an update to its latest operating system for Mac computers and said it's changing development practices after a significant security flaw was disclosed Tuesday that allowed people to log in without a password, potentially making private user data vulnerable.


Forbes writer Thomas Fox-Brewster wrote yesterday that the bug "may go down as one of the most embarrassing vulnerabilities in Apple history". Those who have Macs running High Sierra 10.13.0, an older version, have found that downloading the security patch solves the critical problem, but when they update to the latest version of High Sierra, 10.13.1, the root bug resurfaces, undoing the patch's effectivity. This, in particular, provides access to the login screen in Mac blocked. To enable the Root User and set a password, please follow the instructions here: https://support.apple.com/en-us/HT204012. However, the bug is not fixed in that case until the user reboots the computer.

"A password prompt that authenticates as root with an empty password would be a black eye for any OS". The next day Apple released a security update for High Sierra and apologized to all Mac users for the mistake. When that happens, "Make sure to update your Macs and MacBooks at your earliest opportunity after it is released", he added.
