Macos big sur update time11/11/2023 You could always install macOS Big Sur on its own partition (for now) The Review Files option helps you find large files you may no longer need or apps your system can’t use, and the File Browser sorts your various key folders by size you can see what’s eating up so much space on your Mac. You can also click on the Apple icon in your Menu Bar and select About This Mac > Storage > Manage, which pulls up a handy little list of options for optimising your Mac’s storage (say, by deleting Apple TV movies or shows you’ve already watched). Run through Finder and delete any apps you’ve installed that you haven’t used in forever, which should be obvious if you sort by “Date Last Opened.” Screenshot: David Murphy Other than that, you might as well take some time to do a little housekeeping before you install macOS Big Sur (or while it downloads). (Obviously, anything you do on your Mac between the backup and the Big Sur installation will disappear, unless it was automatically backed up somewhere else.)

Speaking of, if you have any kind of external storage sitting around, such as a spare USB drive or one of Apple’s fancy Time Capsules, run a Time Machine backup. It wouldn’t hurt to duplicate your documents and photos elsewhere (on Google, perhaps, or any number of other cloud-storage services). At minimum, I’d triple-check that you’ve been saving your precious documents, photographs, and everything else to iCloud (via System Preferences > Apple ID > iCloud). Otherwise, I would recommend fully backing up your Mac, because it might be a lot harder to save your files if an upgrade disaster strikes - if you even can. If you’re moving from an older version of macOS, however, you’ll want to make sure that any 32-bit apps you’re using (viewable via the Apple button > About This Mac > System Report > “Legacy Software,” under the Software section in the left sidebar) are compatible with the 64-bit app requirements of macOS Catalina and beyond - which includes macOS Big Sur, of course. If you’re moving from macOS Catalina to macOS Big Sur, I don’t think you’ll have very much to do to prepare. I’ve never had an issue installing new Apple system updates, but that doesn’t mean problems can’t pop up from time to time. Should I do anything before I update to macOS Big Sur? Then, update to the final version of macOS Big Sur as you normally would. If you’re prompted to restart your system, do that. That should pop up this window: Screenshot: David MurphyĬlick on “Restore Defaults” to unenroll from the beta program. If you’ve been playing around with macOS Big Sure via its beta, you can unenroll your system prior to updating to the public release macOS Big Sur by clicking on the “Details” link under “Software Update” in the similarly named screen. I like to stick with a stable build until there’s something truly interesting in a new beta that’s worth trying out early. That way, I can decide if I want to hop into subsequent betas for the next minor updates Apple is working on. Though it’s typically not an issue, I like to remove my beta profiles before I upgrade to the final release of an operating system. What if I’m already using the macOS Big Sur beta? After that, click on “Update Now” to launch the process. Make sure you’ve checked the “Automatically keep my Mac up to date” box if you want to do just that in the future. Once macOS Big Sur releases today, you’ll only need to click on the Apple logo in the upper-left corner of your Mac, then open System Preferences > Software Update. (Screenshot: David Murphy)Īs always, the process couldn’t be any easier. This is just an example using the macOS Big Sur beta. How do I install macOS Big Sur? You’ll see slightly different language for the actual macOS Big Sur update. Until then, you can at least use this tool to practice stuffing macOS Catalina on your even older system, if it doesn’t have it. It’s certainly possible we’ll see some kind of third-party installer that lets you slap macOS Big Sur on an unsupported system, but one is not available yet. If you don’t have a compatible system, then your macOS trip ends with macOS Catalina, the previous operating system. However, just in case you have an incredibly old system, here’s a list of compatible Apple desktops and laptops: MacBooks Most Macs systems released over the past seven years will be able to enjoy a free upgrade to macOS Big Sur.
