When Should You Should Upgrade to macOS 15 Sequoia, iOS 18, iPadOS 18, watchOS 11, tvOS 18, and visionOS 2?
The calendar has flipped over to September, so Apple will soon release major upgrades for all its operating systems. iOS 18 and watchOS 11 will undoubtedly ship alongside new iPhone and Apple Watch models mid-month. iPadOS 18 is likely to accompany iOS 18, as are tvOS 18 and visionOS 2. Although Apple has sometimes delayed the release of macOS until later in the year, we anticipate that Apple will release macOS 15 Sequoia earlier this year, probably with its siblings. That’s because the company has already said it will release the initial Apple Intelligence features in iOS 18.1, iPadOS 18.1, and macOS 15.1; those will probably debut in October or November.
Apple previewed these releases at its Worldwide Developers Conference in June, and many people have been testing the public betas since. Once Apple judges each of its operating systems to be ready for public consumption, the question arises—when should you upgrade?
Note that we say when and not if. There’s no harm in delaying a major operating system upgrade until Apple has sanded off any rough edges that slipped through testing. But waiting too long puts you at risk from security vulnerabilities, increases compatibility annoyances, and prevents you from taking advantage of new features. Plus, when you buy a new Mac, iPhone, or iPad after these operating systems have shipped, you’ll get the latest version, which could pose problems for your existing apps or compatibility with older hardware or workflows. It’s best to be prepared if you have to replace a device unexpectedly.
Given that we don’t know precisely when each operating system will come out, here’s our recommendation for the general upgrade order that we anticipate and how long we suggest waiting after the release appears. We also share a few new features that might encourage you to upgrade, assuming you have a device that’s new enough to take advantage of them.
Remember, always make a backup before upgrading a Mac, iPhone, or iPad so you can revert if necessary.
iOS 18
It’s usually safe to upgrade iOS fairly quickly because Apple puts significant effort into ensuring that the new iOS version is a good experience for those who buy the new iPhones that come with it. However, because iPhones are so crucial to our everyday lives, it’s worth delaying the upgrade to iOS 18 for a week or two, just in case. After that, you can install it and enjoy the new features.
Even before the Apple Intelligence features start appearing in iOS 18.1, there’s plenty to look forward to in iOS 18. Messages via satellite will let you stay in touch even when there’s no cellular or Wi-Fi service. You’ll be able to personalize your Home Screen layout more by placing apps and widgets wherever you want. App icons and widgets get a new Dark look, and you can even tint them all a certain color. Keep prying eyes out of sensitive apps by requiring Face ID to open them. You can now rearrange and resize controls in Control Center, plus create groups of controls accessible with a single continuous swipe. You can even swap out the flashlight and camera icons on the Lock Screen for other controls. Photos has been redesigned (and simplified after public outcry during the beta). Messages lets you use bold, italics, underline, and strikethrough, but more interesting is the ability to send tapback responses with any emoji or sticker—it’s a great way to respond quickly to messages. Maps gains topo maps and trail networks, including all US national parks, and a new Passwords app extracts your logins and passwords from the Settings app.
