Apple has decided to give its older devices a significant boost with a series of Updates for macOS 11 and various branches of watchOS Designed to keep essential services like iMessage and FaceTime running, these aren't major updates packed with new features, but rather quiet revisions that address the core of the system: the certificates that allow these devices to continue communicating with the company's servers.
For those who continue to use a Older Macs or Apple Watches from several generations ago in Spain and the rest of EuropeThe move is especially relevant. These updates will determine whether they can continue sending messages and making video calls normally for years to come, without suddenly encountering activation errors or being blocked by expired certificates.
What Apple has updated in macOS 11 and in the different branches of watchOS
The core of this round of patches consists of macOS 11.7.11, watchOS 10.6.2 and watchOS 9.6.4These updates are accompanied by other more specific revisions such as watchOS 6.3.1 and even a security update for macOS Catalina identified as 2026-001. They all aim for the same goal: to extend the lifespan of computers that can no longer install the latest major system versions.
On the Mac, the protagonist is macOS Big Sur 11.7.11 (build 20G1443)This update is intended for computers stuck on this version and incompatible with newer macOS versions. According to Apple's support documentation, this update extends the certification used by features like iMessage, FaceTime, and device activation, which is crucial for their continued functionality beyond January 2027.
In the smartwatch arena, Apple has made moves on several fronts. For one thing, Watch 10.6.2 It reaches watches that were already on the tenth generation of the system but will not be able to upgrade to the latest one. On the other hand, watchOS 9.6.4 (build 20U512) It is positioned as the last major version for models that rely on iPhones locked to iOS 16, and is complemented by a series of parallel patches.
Along with them, the company has published watchOS 6.3.1 (build 17U224) for even older watches and macOS Catalina Security Update 2026-001 These updates are for computers that remained on that version of the desktop operating system. They may seem modest, but they ensure compatibility with critical services and strengthen the security of systems that would otherwise have been left virtually unusable.
These reviews are in addition to recent iOS 16 updates designed for phones that haven't been able to upgrade to iOS 17. iOS 16.7.13 arrived alongside some of these watchOS versions, and later Apple released iOS 16.7.14 to fix a bug detected in the previous revision, keeping features like iMessage, FaceTime, and other native apps stable.
Renewed certificates: the key to continuing to use iMessage and FaceTime until 2027
The most important change of macOS 11.7.11, watchOS 10.6.2 and watchOS 9.6.4 It's not immediately noticeable because it doesn't add new icons or different menus. The relevant aspect lies in the technical side: all these versions They extend the validity of the certificate used for device activation, iMessage, and FaceTime. to communicate securely with Apple's servers.
These certificates function as digital credentials These credentials are displayed by the system each time you try to activate a Mac or Apple Watch, sign in to iMessage, or make a FaceTime video call. If they expire without an update to renew them, the user may start experiencing connection errors or crashes when trying to use services that, until then, worked without issue.
Apple explains in its support notes that the extension introduced will allow iMessage, FaceTime, and activation processes will continue to function normally after January 2027 on covered devices. In other words, a period of several years is guaranteed during which these services will continue to accept connections from devices running macOS Big Sur and the affected versions of watchOS.
In practice, this means that Anyone who owns a Big Sur-compatible Mac or an Apple Watch from previous generations You won't have to worry, at least in the short and medium term, about a sudden disruption to your communications due to a simple expired certificate. The hardware can continue to be used for encrypted messaging and video calls within the ecosystem without needing to update the device solely through software.
In addition to avoiding connection errors, Updating the certificate helps maintain the expected level of security in services that handle sensitive information and personal communications. Without this update, many users would be tempted to seek alternative or less secure solutions, with the consequent increase in risk.
Mac models with Big Sur that receive macOS 11.7.11 and extra support
The update macOS BigSur 11.7.11 It's designed for a specific list of computers that, due to hardware limitations, can no longer upgrade to macOS 12 or later versions. Among the compatible devices are several models still very common in Spanish homes and offices.
Apple mentions the following as recipients of macOS 11.7.11 to devices such as:
- MacBook (12-inch, 2015).
- MacBook Air (2013 and 2014 models).
- MacBook Pro (2013 and 2014 models).
- iMac (2014 models).
For these computers, the new patch means a few extra years of stable operation with iMessage, FaceTime, and activation processesThis is especially important in contexts where the goal is to extend the lifespan of hardware as much as possible. It's a common situation in small businesses, educational institutions, and many homes in Spain and other European countries.
In addition to Big Sur, Apple maintains a basic level of support for even older machines through macOS Catalina Security Update 2026-001This rapid update focuses on closing vulnerabilities and ensuring compatibility with essential services, without altering the interface or adding flashy features.
The systems receiving this security patch include:
- 2012 MacBook Air.
- 2012 MacBook Pro.
- Mac mini from late 2012.
- 2012 and 2013 iMac.
In all these cases, the philosophy is the same: to keep the system secure and ensure access to Apple's cloud services whenever possible, so that users can continue working, studying or browsing with a reasonable level of security despite the age of the hardware.
Apple Watch with watchOS 10.6.2 and 9.6.4: Who gets extra usage time?
In the wearables sector, Apple has deployed a similar strategy to ensure that its older watches continue to work seamlessly alongside older iPhones. watchOS 10.6.2 and watchOS 9.6.4 These are the two main branches that concentrate these improvements.
On one hand, watchOS 10.6.2 is available for Apple Watch Series 4, Apple Watch Series 5, and the original Apple Watch SEThese are models that can no longer access the latest generation of the system, but with this patch they receive an effective extension of support: renewed certificates, security patches and greater overall stability.
For another, watchOS 9.6.4 is geared towards iPhone-linked watches that are stuck on iOS 16, such as the iPhone 8, iPhone 8 Plus and iPhone X, which cannot be updated to iOS 17. This version is presented as the last major revision that these devices will receive, so its role is to close the chapter with updated credentials and reinforced security.
Meanwhile, Apple hasn't forgotten about even older models and has released Watch 6.3.1 for those who remain in that generation of the system. Here, the objective is once again to maintain Enough bug fixes and security patches to keep the watch paired with the iPhone and using communication functions without serious incidents.
All these versions of watchOS share a long-term maintenance approach: to ensure that the watch continues to securely receive information from Apple's serversThis allows services like iMessage and FaceTime, used via the iPhone, to remain unaffected by expiring certificates or known vulnerabilities.
iOS 16 updates that accompany macOS and watchOS patches
The round of revisions isn't limited to computers and watches. Apple has continued to take care of its customers. iPhones that couldn't make the jump to iOS 17 with new versions within the 16.x branch, a practice that, while not daily, has become relatively common when bugs appear or potential security risks are detected.
Alongside the release of watchOS 9.6.4 for watches paired with these phones, the company launched iOS 16.7.13 for devices such as the iPhone 8, 8 Plus, and X. These are devices that were locked on iOS 16 because they were not compatible with later versions, but they still have a large user base in Europe.
Shortly afterwards, Apple also released iOS 16.7.14 for the same models, with the intention of correcting a bug detected in the previous update. The revision is focused on improving the stability and security patchesas well as ensuring that key applications such as iMessage or FaceTime continue to function normally.
As explained, version 16.7.13 caused problems with some mobile operators in Australia, which led to Temporarily withdraw the update and quickly prepare for 16.7.14 as a solution. Although the impact in Europe was limited, it is still recommended to install the latest update to minimize risks and keep the system up to date.
Taken together, these iOS versions demonstrate that Apple Continue to pay attention to devices that have fallen a step behindoccasionally releasing specific patches to close vulnerabilities or correct specific errors, even though they are no longer part of the system's first line of development.
How to install macOS 11.7.11 and the latest versions of watchOS
Installing these updates is done through the usual methods, without any special steps. In the case of computers, macOS 11.7.11 can be downloaded from the "Software Update" section. within the Settings app or in System Preferences, depending on the version each device has.
Once in that section, the system It automatically detects the availability of macOS Big Sur 11.7.11 For compatible Macs, it allows you to start the download and subsequent installation. It's recommended to have sufficient battery power or to have the computer plugged into a power source, and as always, to have a recent backup in case of any unforeseen issues during the process.
On watches, the procedure necessarily involves a paired iPhone. To install For watchOS 10.6.2 or watchOS 9.6.4, you need to open the Apple Watch (Watch) app.Access the software update section and follow the on-screen instructions until the process is complete.
The Apple Watch must be connected to the charger or with sufficient battery and near the iPhonewhich in turn requires a stable Wi-Fi connection.

Impact in Spain and Europe: more years of use without giving up iMessage and FaceTime
In markets like Spain, where it is common for a Macs from 2013 or 2014 are still in use many years after purchaseThese updates have a significant practical impact. The same is true for Apple Watches, which are passed down from parents to children, repurposed as assistive devices, or used in work environments where technology isn't constantly being updated.
Without the certificate renewal introduced in macOS 11.7.11 and the various branches of watchOSMany of these devices would have faced, within a few years, the inability to use basic services like iMessage or FaceTime, despite still functioning correctly at the hardware level. This would have forced users to purchase new devices earlier for purely software-related reasons.
With the change implemented, Apple is aligning itself in some way with the European trend towards promoting durability and repair of electronic productsExtending the lifespan of software and maintaining compatibility with essential services is complemented by initiatives such as the right to repair or the obligation to have spare parts available for a longer period.
For the average user, the message is quite simple: If your Mac with Big Sur or your Apple Watch appears on the compatibility list for these versions, it's worth updating.There won't be any surprises at the interface level, but there will be significant improvements in security, stability, and continuity of services used daily.
Ultimately, The combination of macOS Big Sur 11.7.11, security updates for macOS Catalina, and the new versions of watchOS and iOS 16 This shows that, even though the spotlight is on the latest releases, Apple continues to dedicate resources to its older devices. This extra attention allows many users in Spain and the rest of Europe to continue using their older Macs and Apple Watches with fully functional iMessage and FaceTime, giving them several years before they need to consider upgrading.
