Mac Update 10.9 Download

Tech observers were seriously taken aback when Apple took several days to address a security flaw in OS X 10.9 Mavericks after quickly fixing the same bug in iOS. The vulnerability comes from an improper implementation of SSL and TLS—the standard encryption systems used for secure Internet connections.

PCMag security expert Fahmida Rashid said users should update immediately, noting that the bug allows attackers to 'launch a man-in-the-middle attack and eavesdrop on all user activity.' It does this by incorrectly validating the certificates that prove that, for example, the Web page you're seeing is really coming from your bank. An attacker on the same Wi-Fi network could spoof the bank's site and see any information you send.

Mac Update 10.9 Download Free

The latest software makes your Mac device compatible with the new technological developments. Still, it also makes the existing OS obsolete. That's why most Mac users with old devices try to update their Mac to OS X El Capitan. However, you can't update your Mac to El Capitan 10.11 if your Mac runs on software later than Mac OS X 10.6 Snow Leopard. Firefox version 78 is the last supported Firefox version for Mac users of OS X 10.9 Mavericks, OS X 10.10 Yosemite and OS X 10.11 El Capitan. These users will be moved to the Firefox Extended Support Release (ESR) channel by an application update. This will provide security updates until the next ESR update in July 2021, after which the affected users will no longer receive security updates.

How to Update

Luckily, Apple has patched the vulnerability—and added a few desirable user feature enhancements, too boot. Here's how to get the update:10.9
  • Make sure that you're on a trusted network such as your home or work connection.
  • Back up your Mac using Time Machine or another backup system. (But if you don't have access to these, it's more important to perform the upgrade, even without a backup. You could just save cricital files to external storage as a half measure.)
  • Make sure your Mac is plugged in if it's a laptop.
  • Tap the Apple icon at the top left of your Mac's main menu bar, and choose 'Software Update...'
