macOS Big Sur 11.7.11 Update Released Years After Retirement

macOS Big Sur 11.7.11 Update is now available!

Well this is a new one… Apple just released macOS Big Sur 11.7.11 (20G1443) Update!

Apple ended support for macOS Big Sur in September 2023. With this release, Big Sur now ties OS X Tiger (10.4.11) for the most point‑release updates in macOS history. Who would have thought we’d see another update for Big Sur? We did get a hint last week when Apple pushed out several older iOS updates, but I still didn’t expect any new macOS releases. I’m glad I was wrong.

This will allow important services like device activation, FaceTime, iMessage and other services to continue to work after the current certificates expires in January 2027.

I applaud Apple for doing this. We need to recognize that for many people, older computers are their only means of communication. Not everyone has the resources to buy a new device. This update will help those users continue using their Macs and iPhones. It’s especially important to remember how impactful this is in impoverished areas around the world.

Even though Apple updated Big Sur to address these certificate issues, it’s important to remember that the OS is no longer security‑supported. No security updates have been released for it in over two years. If possible, please use OCLP or upgrade to at least the last supported version, macOS Sonoma.

Big Sur Update Quick Overview

macOS Big Sur 11.7.11 Update – This update extends the certification required by features such as iMessage, FaceTime, and device activation to continue working after January 2027.
Big Sur 11.7.11 Full installer is available!
Apple stopped releasing M1 IPSW restore files after version 11.6.
Safari update = 16.6.1 is the latest version available

macOS Big Sur Update Summary

New Features – None
Resolved Issues – Multiple certificates were updated
Security Fixes – None

macOS Background Security Improvement Update (BSI) Database

macOS Tahoe Background Security Improvement Updates (BSI)

Apple has just released the very first macOS Tahoe Background Security Improvement Update: macOS Tahoe 26.3.1 (a) 25D771280a)

UPDATED: 3/19/26

If this sounds familiar, you are right! Starting in macOS Ventura, Apple added a new security feature called “Rapid Security Response” or RSR for short. This new update system was designed so that Apple can quickly deploy a small targeted security update. Users would no longer have to wait for a large OS updates to be fully protected from security vulnerabilities.

Database of all Tahoe BSI Updates

This database will contain changes in the OS Tahoe version number. It will also contain changes in the Safari version number. These changes will occur if there is any, when a BSI update is made available.

NOTE: I’ve included a direct Apple download link for each BSI. The update can’t be installed manually, but you can inspect it. The BSI manual download file format is .aea

Tahoe 26.2	No BSI

macOS Tahoe BSI Safari Updates

Ventura RSR Version	Safari Version	Date
Safari 26.3 Beta	None	No RSR
Safari 26.2	None	No RSR

NOTE: BSI and macOS Updates are cumulative.

Example: Tahoe 26.3 (a) <– Tahoe 26.3 (b) <– Tahoe 26.4

Each new version of macOS includes the earlier fixes.

Thanks

[FIXED!] Lion Recovery Error Can’t download the additional components needed to install Mac OS X.

Multiple OS X Lion Recovery Errors – Install Error Can’t download the additional components needed to install Mac OS X.

As of 2025, Mac Internet Recovery versions from 10.7-10.13 are online, but have additional issues . In this article we will focus on the OS X 10.7 Lion install issues from Recovery

In my current quest to fix every single macOS Recovery version from 10.7 to 10.13, the most popular version requested was actually OS X Lion! While that article was helpful if you booted to OS X Lion Internet Recovery, users could have additional problems. One of those problems is this error “Can't download the additional components needed to install Mac OS X” This error can happen with both internet recovery and with a USB Installer. You can also get the error ” An error occurred while preparing the installation. Try running this application again.“

OS X Lion was actually the very first version of Internet Recovery. So it is now the oldest version still online. The fact at Apple is still maintaining Lion’s Internet Recovery server is great, but it is now completely broken.

Keep in mind, this is NOT the Date and Time issue that most articles point to. That fix worked in the past but does not work anymore. So internal recovery (command R) and Internet Recovery are currently unable to download and install OS X Lion in its current state.

Previously I provided fixes and workarounds for macOS High Sierra and macOS Sierra Recovery issues.

The other OS X Lion Recovery problem error is – An error occurred while preparing the installation. Try running this application again. You can go to this article for that issue – https://mrmacintosh.com/fixed-lion-recovery-an-error-occurred-while-preparing-the-installation-try-running-this-application-again/

Let’s get jump in and get Lion Recovery fixed!

What is the root problem?
How to fix the issue?
Fix #1 Downloading OS X Lion from Apple and creating a USB installer.
Fix #2 Downloading OS X Lion from INSIDE Lion Recovery and using it to Install Lion with it!
Extra Option: Creating a OS X Lion USB installer drive INSIDE OS X Lion Recovery!
