Patrick Atis securely wiped his drive, and then wanted to reinstall Yosemite, the installer for which he has on an external hard drive. However, after he booted into OS X Recovery (holding down Command-R at startup), he was only offered the option to download OS X through the App Store, and Yosemite wasn’t an option. What path could he take forward?

I'm trying to run a basic assembly file using 64 Bit Mac OS X Lion, using nasm and ld which are installed by default with Xcode. I've written an assembly file, which prints a character, and I got it to build using nasm. Nasm -f elf -o program.o main.asm. However, when I go. Feb 05, 2021 Check compatibility If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that it's too old to be opened on this version of macOS, or that your Mac doesn't have enough free storage space for the installation. It's free, so the logical approach is to go ahead and upgrade. Here is how it can be done. The Steps for Upgrading to Mac OS X El 10.11 Capitan. The following is steps for upgrading to Mac OS X 10.11 Capitan: Visit the Mac App Store. Locate the OS X El Capitan Page. Click the Download button. Follow the simple instructions to complete the upgrade. Make sure you are ready to downgrade your operating system by checking in with what version of OS X you already have and ensuring you have enough hard drive room to download the older version. Clicking the apple in the top left corner of your desktop and selecting About This Mac will allow you to see what OS X version you are currently running. Unlike previous versions of Mac OS X, Apple released OS X Mavericks onto the Mac App Store for free, meaning that the Unibeast method is now 100% free to use. However, using a distro to install Mac OS X still offers a far share of advantages: You don't need a real Mac.

Recovery will reinstall the same version of OS X that was on your Mac, even though it’s been erased. Patrick should therefore be prompted to install Yosemite. That didn’t happen in his case. With an erased 2009 MacBook Pro, as Patrick has, he can’t use Internet Recovery, which will reinstall the original operating system that came with the Mac. If that had worked, you could install that older OS, then copy the Yosemite installer, and use it to upgrade, although an intermediate OS X installation might even be required.

Since this isn’t working for Patrick, the better course is to create on another Mac a bootable Yosemite installer following Dan Frakes’ instructions. Patrick has the Yosemite installer, but if you need an older installer, you can launch App Store on a Mac and then use the Purchased tab to scroll down and find older releases—they don’t show up by searching.

Start up from macOS Recovery

Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:

Apple silicon

Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.

Intel processor

Make sure that your Mac has a connection to the internet. Then turn on your Mac and immediately press and hold Command (⌘)-R until you see an Apple logo or other image.

If you're asked to select a user you know the password for, select the user, click Next, then enter their administrator password.

Reinstall macOS

Select Reinstall macOS from the utilities window in macOS Recovery, then click Continue and follow the onscreen instructions.

Follow these guidelines during installation:

• If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
• If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
• If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
• Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.

After installation is complete, your Mac might restart to a setup assistant. If you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.

Other macOS installation options

When you install macOS from Recovery, you get the current version of the most recently installed macOS, with some exceptions:

• On an Intel-based Mac: If you use Shift-Option-Command-R during startup, you're offered the macOS that came with your Mac, or the closest version still available. If you use Option-Command-R during startup, in most cases you're offered the latest macOS that is compatible with your Mac. Otherwise you're offered the macOS that came with your Mac, or the closest version still available.
• If the Mac logic board was just replaced, you may be offered only the latest macOS that is compatible with your Mac. If you just erased your entire startup disk, you may be offered only the macOS that came with your Mac, or the closest version still available.

You can also use these methods to install macOS, if the macOS is compatible with your Mac:

• Use the App Store to download and install the latest macOS.
• Use the App Store or a web browser to download and install an earlier macOS.
• Use a USB flash drive or other secondary volume to create a bootable installer.
