If you run Mac OS X Yosemite, don't use an emoji in your password

As at least one poor soul found out the hard way, there's a very good reason that Apple's latest OS X, El Capitan, doesn't let you use an emoji in your login password.

Apple doesn't have the same rule with OS X Yosemite. A user on Stack Exchange's Ask Different forum explained that he had used an emoji in his password on Yosemite — and then wasn't able to log in to his account. He originally posted about it back in August, but it's a PSA worth repeating.

New privilege escalation exploit discovered in OS X Yosemite, also affects just-released 10.10.5

Just days after patching the DYLD_PRINT_TO_FILE vulnerability with a new OS X point release, Apple's desktop operating system has been hit with yet another zero-day exploit that would allow an attacker to gain root access without using a password.

The exploit was discovered by Italian developer Luca Todesco, who relies on a combination of attacks — including a null pointer dereference in OS X's IOKit — to drop a proof-of-concept payload into a root shell. It affects every version of OS X Yosemite, but seems to have been mitigated in OS X El Capitan, which is nearing release.

Apple on Thursday released a second beta build of its upcoming OS X 10.10.5 Yosemite update to developers for testing, including what appears to be only minor tweaks and bug fixes.

The latest beta, build 14F19a, comes a little over two weeks after the first beta version was pushed out to developers and users signed up for Apple's public beta program.

Like the first beta, today's build brings minor tweaks and bug fixes aimed at improving system stability, app compatibility and security.

You can bypass Apple's space-age security and gain administrator-level privileges on an OS X Yosemite Mac using code that fits in a tweet.

Yosemite, aka version 10.10, is the latest stable release of the Mac operating system, so a lot of people are affected by this vulnerability. The security bug can be exploited by a logged-in attacker or malware on the computer to gain total unauthorized control of the Mac. It is documented here by iOS and OS X guru Stefan Esser.

Many of Windows 10′s best features showed up in Mac OS X years ago, including virtual desktops, Expose-like window management, and a notification center. Mac OS X 10.10 Yosemite has some other ideas Microsoft should copy for version 10 of its own operating system, too.

All operating systems copy from each other, and that’s a good thing. This isn’t about who invented what first — it’s about improving the operating systems billions of people use every day.
