如何在没有恢复分区的情况下在Mac上安装MACO？

如果Mac没有恢复分区，可以通过创建外部可启动安装器来安装macOS。具体步骤如下：1. 使用至少12GB的U盘下载macOS安装程序（如Ventura、Monterey或Big Sur），并通过磁盘工具将其格式化为“Mac OS Extended (Journaled)”。2. 在终端中运行createinstallmedia命令，将U盘转换为可启动安装器。3. 关闭Mac并插入U盘，开机时按住Option键选择U盘启动。4. 进入macOS安装环境后，使用磁盘工具选择内部硬盘并格式化为APFS或Mac OS Extended。5. 最后按照屏幕提示完成macOS安装，安装过程大约需要20至40分钟，完成后Mac会自动重启进入设置助手。

If your Mac doesn't have a recovery partition, installing macOS might feel tricky at first, but it's definitely doable. The key is to create an external bootable installer and use that to get the job done.

Here’s how you can handle it step by step:

Create a bootable macOS installer on a USB drive

To install macOS without a recovery partition, you’ll need a USB flash drive (at least 12GB or more) to make a bootable installer. Apple provides tools for this, and it's straightforward if you follow the right steps.

• Download the macOS installer from the App Store (like Ventura, Monterey, or Big Sur — depends on what your Mac supports).

  

• Plug in your USB drive and format it using Disk Utility: name it something like “MacOS Install,” and choose "Mac OS Extended (Journaled)" as the format.

• Open Terminal and run the createinstallmedia command. For example, if you downloaded Ventura, the command would look like:

  sudo /Applications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/MacOS\ Install

This process will erase the USB drive and turn it into a full macOS installer.

Boot from the USB installer

Once you’ve created the bootable USB, you’re ready to start the installation process.

• Shut down your Mac.
• Plug in the USB drive.
• Turn on your Mac while holding the Option (⌥) key — this brings up the startup manager where you should see your USB drive listed.
• Select the USB volume and press Enter to boot from it.

From here, you'll land in the macOS Installer environment, which includes Disk Utility and the actual macOS installation option.

Use Disk Utility to prepare your internal drive

Before installing macOS, you need to make sure your internal drive is formatted correctly.

• From the installer screen, go to Utilities > Disk Utility.
• Select your main internal drive (not just a partition), and click "Erase."
• Choose APFS (or Mac OS Extended if needed) as the format, depending on your Mac model and macOS version.
• Give it a name like “Macintosh HD” and proceed with erasing.

Once that’s done, close Disk Utility and proceed to install macOS on the newly formatted drive.

Install macOS from the installer

Now that your drive is ready, the last step is to actually install macOS.

• Follow the on-screen instructions — select your target disk (the one you just erased), and let the installer do its thing.
• It may take 20–40 minutes depending on your hardware.
• Once installed, your Mac should restart automatically and boot into the setup assistant.

Make sure to keep your USB installer handy in case you ever need to repair or reinstall macOS again.

That’s basically all there is to it. You don’t need a recovery partition if you've got a bootable installer ready. Just remember to match macOS versions to your Mac’s compatibility, and double-check the formatting steps so everything boots properly.
