What is the best format for USB drive on Mac?
The best format for a USB drive on Mac will depend on your specific needs and intended use for the drive. Here are some common considerations:
1. Compatibility: If you primarily use the USB drive with Mac systems, then the default format, macOS Extended (also known as HFS+), is a reliable choice. It offers excellent compatibility and performance with macOS.
2. Cross-Platform Compatibility: If you need to use the USB drive with both Mac and Windows systems, it is recommended to use the ExFAT file system. ExFAT offers good compatibility between macOS and Windows, allowing you to read and write files on both operating systems without the need for additional software.
3. Security: If you’re concerned about data security and want to encrypt the USB drive, you can consider formatting it as macOS Extended (Journaled, Encrypted) or APFS (Encrypted). These formats provide built-in encryption options, ensuring that your data remains protected even if the drive gets lost or stolen.
4. File Size Limitations: If you frequently transfer large files (over 4GB) to and from the USB drive, opting for ExFAT or APFS is recommended. Both formats offer support for larger file sizes, whereas macOS Extended has a file size limitation of 4GB.
To format a USB drive on a Mac, follow these steps:

How do I force a USB to format on a Mac terminal?
To force format a USB drive using the Mac terminal, follow these steps:
1. Connect the USB drive to your Mac.
2. Open the Terminal application. You can find it in the Applications > Utilities folder, or you can use the Spotlight search (Command + Space) to locate it quickly.
3. Type the following command to list all the connected disks and find the identifier for your USB drive:

diskutil list
"`
Look for your USB drive, which might be labeled as something like `/dev/disk2` or `/dev/disk3`. Note down the identifier for reference in the next step.
4. Run the following command to unmount the USB drive:
"`
diskutil unmountDisk /dev/disk
"`
Replace `
5. Finally, enter the following command to force format the USB drive using the FAT32 file system:
"`
sudo newfs_msdos -F 32 /dev/disk
"`
As before, replace `
Please note that this process will permanently erase all data on the USB drive, so ensure you have a backup if there’s any important data present. Use caution while performing these steps to avoid formatting the wrong disk by mistake.
Should USB be NTFS or FAT32 Mac?
When it comes to choosing the file system format for a USB drive on a Mac, there are a few considerations to keep in mind. Here’s a professional perspective on whether you should opt for NTFS or FAT32:
1. Compatibility: FAT32 is a universally supported file system that works seamlessly across Mac, Windows, and Linux platforms. If you frequently exchange files between different operating systems or share your USB drive with others, FAT32 is a safe choice. On the other hand, NTFS is primarily used in Windows environments and may have limited compatibility on macOS and Linux systems. Therefore, if you primarily use your USB drive on a Mac, FAT32 may serve your needs better.
2. File Size Limits: One crucial factor to consider is the maximum file size that each file system supports. FAT32 imposes a file size limit of 4GB, which may be a constraint when working with large media files or disk images. NTFS, on the other hand, supports much larger file sizes, theoretically up to 16TB. If you frequently work with large files, NTFS may be more suitable for your requirements.
3. Advanced Features: NTFS offers several advanced features, such as file encryption, permissions, and journaling, that provide improved security and robustness. If you require these advanced features, especially for data protection and access control, NTFS would be the better option for you. However, please note that macOS has limited support for writing to NTFS out-of-the-box, and you may need third-party software to enable full NTFS write access.
Considering these factors, it is recommended to use the FAT32 file system if you frequently share your USB drive across different platforms and file size limitations are not a concern. If you predominantly use your USB drive on a Mac, have large files beyond the 4GB limit, or require advanced features like encryption and permissions, using the NTFS file system may be more appropriate.
Is FAT32 or exFAT better for Mac?
When it comes to choosing between FAT32 and exFAT for Mac, there are a few factors to consider. Here’s a professional point of view on which file system is better:
1. Compatibility: FAT32 offers better compatibility across different operating systems, including macOS, Windows, and Linux. It allows for easy file sharing between Mac and Windows machines without the need for additional software or drivers. On the other hand, exFAT is also compatible with both Mac and Windows but may require some additional drivers on certain systems.
2. File Size Limitations: FAT32 has a file size limitation of 4GB, which means you cannot store files larger than that. If you work with large files, such as videos or disk images, this limitation can be a hindrance. In contrast, exFAT supports much larger file sizes, allowing you to store files over 4GB without any issues.
3. Disk Size Limitations: While FAT32 has a maximum disk size limitation of 2TB, exFAT doesn’t have such restrictions. If you’re using large external hard drives or SSDs with capacities larger than 2TB, exFAT would be a better choice to make full use of the available storage.
4. Data Recovery: If you accidentally delete files or encounter data corruption, FAT32 provides better data recovery options. There are more data recovery tools available for FAT32 compared to exFAT, which can be helpful in critical situations.
5. Security: In terms of security, both FAT32 and exFAT do not offer built-in file system-level encryption or security features. If data security is a concern, it’s advisable to rely on third-party software solutions or macOS’s built-in encryption methods, irrespective of the file system being used.
In summary, while both FAT32 and exFAT have their advantages, the choice ultimately depends on your specific requirements. If you need broad compatibility across different operating systems, especially older ones, and do not work with large files, FAT32 is a viable choice. However, if you frequently work with large files, storage devices over 2TB, or want a modern file system with better overall performance, exFAT would be the better option for your Mac.
