On May 25, Apple released a mass of “Product Security Updates.” These cover most of their most commonly used devices and some specific pieces of software.
- APPLE-SA-2021-05-25-1 iOS 14.6 and iPadOS 14.6. An update to all currently supported iPhones and iPads. There are currently about 1.8 billion iOS and iPadOS devices.
- APPLE-SA-2021-05-25-2 macOS Big Sur 11.4. This is a comprehensive update to Apple’s current operating system for the Macintosh.
- APPLE-SA-2021-05-25-3 Security Update 2021-004 Mojave. This is a partial update to macOS Mojave 10.14. Though it doesn’t result in a version number change, the update covers a long list of potential vulnerabilities and stability issues.
- APPLE-SA-2021-05-25-4 Security Update 2021-003 Catalina. This is a partial update to macOS Catalina 10.15. Like the Mojave update, it doesn’t result in a version number change, but just the index to the update covers several pages.
- APPLE-SA-2021-05-25-5 Safari 14.1.1. This update specifically brings Safari (and the underlying WebKit infrastructure used by many other pieces of Mac software) up to Safari 14.1.1 on macOS Catalina and macOS Mojave. This update is also bundled into the macOS Big Sur 11.4, iOS 14.6 and iPadOS 14.6 updates mentioned above.
- APPLE-SA-2021-05-25-6 watchOS 7.5. This is an update to all currently supported Apple Watches.
- APPLE-SA-2021-05-25-7 tvOS 14.6. This is an update to all currently supported Apple TV 4K and HD devices. Among other things, it offers support for the new Apple TV Remote.
- APPLE-SA-2021-05-25-8 Boot Camp 6.1.14. Boot Camp is not used by many Macintosh users, but it allows you to partition your boot drive and install Windows on it.
If you have a device that uses any of these operating systems, it is strongly recommended that you update the device immediately.
And — if you have an older device that cannot support these updates, remember that your device is vulnerable to attack.
