How to Download macOS to USB

If you're planning to download macOS Sierra, also known as Mac OS X 10.12, to a USB flash drive, this article will guide you through the process. Before we begin, it's essential to note that the installer and Disk Utility of macOS Sierra are more buggy and slower compared to previous versions.

To start, open the 'App Store' application on your Mac and search for 'macOS Sierra.' The macOS Sierra installer is available from the Mac App Store. As you download the installation file, be prepared to wait patiently, as the process can take significantly longer than expected (up to 50 minutes).

Once you've downloaded the installer, follow these steps to create a bootable USB flash drive:

1. Select 'System Preferences' from the drop-down menu.

2. Click on the Apple icon in the upper left corner of your Mac's screen.

Using a bootable USB flash drive containing the macOS Sierra installer is recommended for a clean installation of the operating system.

With the bootable USB drive ready, you can now use it to install macOS Sierra. Simply insert the USB drive into your Mac, restart your computer while holding down the 'Option' key, and select the USB drive as the startup disk.

How to Download and Install macOS Updates

When an update becomes available for your macOS version, it's crucial to download and install it as soon as possible. Apple releases updates regularly, which often include bug fixes and security patches.

To check for updates, click on the Apple icon in the upper left corner of your Mac's screen and select 'System Preferences.' Click on 'Software Update' to see if any updates are available. If an update is available, click 'Update Now' to download and install it.

Security Vulnerabilities Fixed

The latest update, macOS 12.5 Monterey, fixes several security vulnerabilities. According to the release notes, the update addresses:

* A vulnerability that could allow maliciously crafted web content to execute arbitrary code.

* An issue that may have allowed an application to execute arbitrary code with kernel privileges.

Apple recommends installing this update immediately to protect your Mac from these vulnerabilities.

In conclusion, downloading macOS Sierra to a USB flash drive can be a bit challenging due to the installer's buggy nature. However, by following these steps and being patient, you can successfully create a bootable USB drive and install the operating system.

Remember to always keep your macOS up-to-date with the latest security patches and bug fixes to ensure your Mac remains secure and stable.
