Add as a preferred source on Google

Apple has pushed a new build of OS X Mavericks version 10.9.3, dubbed 13D28, to developers today, according to MacRumors. As has been the case in the past, the developer-only update is available through the Mac App store and Mac Dev Center at this writing.

Mavericks 10.9.3 13D28 is the third version of the OS X Mavericks 10.9.3 beta that has been released to developers. The second build, 13d21, was released only a week ago. It has been almost a month since Apple made the original 10.9.3 beta available to developers.

With the 13D28 build, Apple is pushing developers to work on graphics drivers and audio. To this point, the OS X Mavericks 10.9.3 beta includes support for 4K displays, offers Retina display resolution settings, and adds 60 Hz support to the Macbook Pro with Retina.

In other Mac OS X Mavericks news, Internet advertising network Chitika recently reported that OS X Mavericks has been adopted by 40 percent of U.S. and Canadian-based OS X users since it was released back in October. However, those numbers have varied slightly from one stat tracker to another, with Net Applications indicating that adoption was at 45 percent in February.

It’s currently unclear when the final version of OS X Mavericks 10.9.3 will be released to the public.

This new Mac malware won’t let you use your computer until you surrender your password
This Mac malware turns your own computer against you
AI Generated Image

A newly discovered strain of macOS malware is taking social engineering to an unsettling new level. Instead of exploiting a software vulnerability or silently stealing information in the background, it simply refuses to let you use your Mac until you type in your login password.

Dubbed ClickLock, the malware repeatedly shuts down key macOS processes, disables notifications, displays convincing Apple password prompts, and effectively traps users in a loop that only ends when the correct password is entered. Once that happens, it doesn't just steal the password. It goes after browser data, cryptocurrency wallets, saved credentials, password managers, and much more.

1Password lets Claude inside your accounts without handing over the keys
Claude can now sign in on your behalf while your password stays hidden, though trusting it after login is a separate decision
1Password official

1Password is giving Claude a way into your online accounts without making your passwords part of the bargain. The new 1Password for Claude integration can fill login details while keeping the credentials hidden from Anthropic’s AI agent.

Available now on Mac, the feature kicks in when Claude reaches a sign-in page during a task. Claude requests a saved login, then you approve or deny it. If approved, 1Password submits the credentials through a separate encrypted channel. Passwords and one-time codes never enter Claude’s context or Anthropic’s systems.
