Now that you're all set, it's time to install Sierra on your computer. Step 6: Install macOS Sierra on Your Computer So, close out of the installation screen that pops up, if any. If you do, it will auto-erase the file when your system gets back up and running, which means you won't have the file for your USB drive. Step 1: Download the macOS 10.12 Installerĭownload the new macOS 10.12 Sierra from the Mac App Store-but don't install it when it finishes downloading. So downloading it once and making a bootable USB stick is an easier, faster way to go. The download for macOS Sierra is about 5 GB, and could take some time downloading on each computer individually. If you have multiple computers that need the macOS Sierra upgrade, you'll want to create a bootable install flash drive. You can also use Apple Pay in Safari, unlock your Mac with your Apple Watch, keep all your Mac's desktops and documents in sync, and use all the cool new iMessage features that iOS 10 already sports, among other things. Another great one is the ability to copy/paste between your iOS 10 device and Mac. Siri is definitely the most tempting feature in macOS Sierra, which is more powerful than its iOS equivalent. You will need another Mac to write the installer to create a USB installer from, using Install Disk Creator.While it hasn't gotten as much attention as iOS 10, Apple's big 10.12 update to their Mac operating system is finally out for all to enjoy-and you can download it for free from the Mac App Store right now. Reset the nvram, then try a different thumbdrive using Install Disk Creator.Įl Capitan can be downloaded here. it won’t let me download from the internet, I don’t have another Mac and I can’t seem to get a usb to work to boot from, can anyone help or point me in the right direction? I have a 2009 MacBook and I’ve been trying and searching for a week on how to restore OS X. But since El Capitan, Apple has included a createinstallmedia script inside the installer, and I've just used that to great success. This article was what I originally followed when making this drive, although instead of using DiskMaker X like the article recommends, I found Install Disk Creator had better compatibility with some of the older macOS installers. Please make sure the USB is formatted as GPT. I used Install Disk Creator to download the Ventura 13.0. Obviously don't use the same USB-drive that all. If you don't want to create the installer disk manually, I think you can use this app. This is what I do, in fact I bought a few cheap 32 GB USB-drives on Amazon-a 5-pack costs maybe $25-and install different versions of macOS on them when need be. If for some reason installing directly from the installer file doesn't work-you can create a bootable installer disk. Planning to downgrade from Ventura to Monterey You can download the image of OS X El Capitan from apple. I can’t enter to restore mode MacBook Pro 2009 13” After you have the usb boot it by holding ALT. Check your macos version eg High Sierra then use or to create the usb. You can create one using another mac or that mac if it boots up enough. Then you need usb containing macos install media.

Other than using Terminal or DiskMaker X, you can purchase an installer for 10.11 from Amazon or eBay, but who can say if they did it right.Īnything I can do about this? Happens on startup. There is no app or software (that I’m aware of) that you can use to make the installer on a Chromebook, and using TransMac on Windows hasn’t worked for the last couple of years. The verified working methods for creating an installer are using Terminal or DiskMaker X. As far as I know, TransMac hasn’t worked since before 2020 for creating a bootable installer for macOS and although I am not familiar with Anyburn, it may have the same problem. That model of MacBook Air shipped with OS X Mavericks (10.9) and can officially handle up to macOS Big Sur.
