There is a distinction between terminals, and users. ;-p -- PeterN There's a joke in that... Whatever, webservices and terminals are basically the thing.

http://www.theregister.co.uk/2015/08..._exploit_wild/ "The amusing vulnerability in Apple's OS X that grants administrator-level access to anyone who asks is being exploited in the wild by malware. Yeah, malware exists for Macs, this isn't the 1990s. Anyone logged in to a vulnerable OS X computer, or any software running on it, can use the security hole to gain the same privileges as the powerful root user, meaning they can install new programs, change files, remove or add new users, wreck the system, and so on, at will. According to Adam Thomas of Malwarebytes, dodgy software distributed on the internet is now exploiting the vulnerability to inject the VSearch and Genieo adware plus the MacKeeper junkware on to Macs, and point users at an app to download from the official App Store." ... more I just went through an update session of my w8 laptop... 107 patches... Whatever, I feel blindfolded on Windows in comparison with the OSX or Android operating systems. -- teleportation kills |

Only Installer and Software Update can do that, and only using Apple-signed developer packages. There is no "real root". sid: The real root user is the one that signs the packages if they are the only things that can write anywhere. Sandman: No, as I said - there is no "real root". The system is built so that no user privileges, including root, can write files to specific locations unless they are being installed using a specific application using a signed certificate. Which is just what I have been saying. Even if you log on as root you can't actually write everywhere, ergo you are not really root. And this is where we have corrected you - you ARE "really" root. There is no other root that the root account. You're basically saying that if tomorrow the president lost his power to launch missiles, he's not "really" president. Well if you stretch the missiles bit to 'any important decisions' then yes, who ever actually makes those decisions is really in charge, regardless of the name you give to either. And to be clear I am using the term root as it would traditionally be used not how it is being misused in the upcoming OSX There is no "misuse" or "traditional" use. http://www.linfo.org/root.html "root Definition" "root is the user name or account that by default has access to all commands and files on a Linux or other Unix-like operating system. It is also referred to as the root account, root user and the superuser. Root privileges are the powers that the root account has on the system. The root account is the most privileged on the system and has absolute power over it (i.e., complete access to all files and commands). Among root's powers are the ability to modify the system in any way desired and to grant and revoke access permissions (i.e., the ability to read, modify and execute specific files and directories) for other users, including any of those that are by default reserved for root." See also https://en.wikipedia.org/wiki/Superuser sid: Being "rooted" doesn't mean only access to a users home directory has been achieved does it? Sandman: Indeed, and in El Capitan, these locations can't be "rooted". I'm unsure whether you don't know how the root account works in unix I do. As I said, I'm not so sure, given what you've said thus far. Sandman: or if you don't know how OSX works right now. Which bit in particular? Are you asking me what parts of OSX you are ignorant about? No. -- sid Well..? It seems that Apple is going the SELinux way by defacto replace Roots superuser privileges with those of an administrator... No, I don't like it either! Now: Guess who the original sponsor for SEL was?;-p https://en.m.wikipedia.org/wiki/Security-Enhanced_Linux -- teleportation kills |
