Macbook USB どこに表示される？
The location of USB ports on a MacBook may vary depending on the specific model you are referring to, but in general, you can find the USB ports on the sides or back of the laptop. Here are some steps to locate the USB ports on your MacBook:
1. Look at the sides of your MacBook: Many MacBook models have USB ports on both sides. They are typically rectangular ports that you can use to connect USB devices such as external storage, printers, or accessories. Check for any rectangular ports with the USB symbol (a three-pronged trident) next to them.
2. Check the back of your MacBook: Some MacBook models may have USB ports located on the back near the hinges. Look for rectangular USB ports with the USB symbol around the back area of your MacBook.
3. Refer to the user manual: If you’re still having trouble locating the USB ports, consult the user manual that came with your MacBook. The manual will provide detailed diagrams and descriptions of your MacBook’s ports, including the USB ports.
Remember that with the advancement of technology, Apple has been moving towards USB-C ports in recent MacBook models. USB-C ports are smaller and have a reversible design, allowing you to connect devices without worrying about plugging them in the wrong way. So, it’s worth considering if your MacBook has USB-C ports instead of traditional USB ports.

Macの起動ディスクにUSBが表示されないのはなぜですか？
When your USB drive is not showing up as a startup disk on your Mac, there could be a few reasons behind it. Let’s explore some possible causes and steps to troubleshoot the issue:
1. Incompatible or faulty USB drive: Ensure that your USB drive is compatible with your Mac and functioning properly. Try connecting the USB drive to another computer to check if it is recognized. If not, try using a different USB drive.
2. Incorrect USB port or connection: Verify that you are using a USB port that is compatible with your USB drive. Sometimes, connecting the drive via a USB hub or extension may cause issues. Try connecting the USB drive directly to a USB port on your Mac.
3. Improper formatting of the USB drive: Make sure your USB drive is formatted with a file system that macOS supports, such as FAT, exFAT, or macOS Extended (Journaled). If it is formatted with a different file system, your Mac may not recognize it as a startup disk. You can use Disk Utility to format the USB drive correctly.
4. Secure Boot settings: Check if the Secure Boot feature is enabled on your Mac. Secure Boot restricts booting from external drives for security reasons. You can disable Secure Boot by restarting your Mac and holding down the Option key while it boots up. Then, go to the Startup Security Utility in macOS Recovery and disable Secure Boot.
5. Startup disk preferences: Ensure that the USB drive is set as the default startup disk in your Mac’s System Preferences. Go to the Apple menu, select "System Preferences," then choose "Startup Disk." Select the USB drive as the startup disk and restart your Mac.
6. Software or firmware issues: Ensure that your Mac has the latest macOS and firmware updates installed. Outdated software or firmware can sometimes cause compatibility issues with external drives. Update your Mac’s software by going to the Apple menu and selecting "System Preferences," then choose "Software Update" to check for updates.
By following these steps, you should be able to troubleshoot why your USB drive is not appearing as a startup disk on your Mac.
