Light Blue compatibility with macOS 15 Sequoia and iOS 18

Next week, Apple are going to be releasing major upgrades to macOS and iOS. iOS 18 and macOS 15 Sequoia are going to be released on 16 September.

We’ve been testing the current versions of our macOS and iOS apps on the prerelease versions of macOS 15 and iOS 18 and haven’t found any issues. However, please read on for our usual health warning about the dangers of installing a major operating system update as soon as it’s available!

Health warning

As with all major operating system updates, it is a very sensible idea to be cautious about updating your computers until Apple have had a chance to fix some of the bugs that will inevitably be present in macOS Sequoia. Although our testing of Light Blue 2024.1.1 on macOS Sequoia has been positive, there is every chance that Apple could change something that breaks compatibility or that we’ve missed something because we can’t test every conceivable combination of devices and settings.

If you rely on Light Blue to run your business, we would therefore recommend holding off from updating your operating system as soon as macOS Sequoia is available. At the very least, if you really really want to update on day one, make sure that you have at least one computer on the ‘old’ operating system until you’ve had a chance to test that all of the features that you depend on are fully functional.

Also, please note that our testing has been has been focussed on the latest version of our desktop app. The vast majority of our subscribers are already using Light Blue 2024.1.1, and if you’re using an older version of our desktop app then please update to the latest version to ensure that you’re able to take advantage of all of the new features and bug fixes that we’ve been adding. You can update the desktop app by using the ‘Check for updates’ command (in the ‘Light Blue’ menu if you’re on a Mac, or in the ‘Help’ menu if you’re using it on Windows).
