Still, if you prefer a USB drive that works for transferring files between Windows and Mac computers, set FAT32 or exFAT as the format. Don't forget to share the method that works the best for you online to help more USB owners change the file system format for free:
FAT32, as one of the oldest file systems, was first introduced in Windows 95 to replace FAT16 on Windows PCs. FAT32 has ideally become the standard format for most computer systems. Most flash drives available today use the FAT32 file system as their default format, offering high compatibility across Mac and Windows.
However, the FAT32 file system is limited to support a maximum file size of 4GB on Windows 10 and older systems. If you tend to transfer or save files larger than that, exFAT would be an ideal file system format.
The exFAT or Extended FAT file system was introduced in 2006 with Windows XP and was planned as a great means of overcoming the limitations of the FAT32 system. The exFAT file system is optimized for flash drives and works great for both internal and flash drives.
Key differences between ExFAT and FAT32:
| Comparison | FAT32 | exFAT |
|---|---|---|
| Introduced In | With Windows 95 | In 2006 with Windows XP |
| Compatibility with Flash Drives | Easy to use, quicker | Best meant for USB flash drive & external USB drives |
| Windows Compatibility | Works with all Windows versions | Works with all Mac versions |
| Special Configuration | Not needed | Mac device needs additional software |
| Size Limit | Max file size limited to 4GB, no limit on Windows 11 | No size limit |
Obviously, according to the comparison table, the exFAT file system should be the right choice when compared to the FAT32 for a wider range of reasons that have already been outlined above.
In a word, we'd suggest you take exFAT as the default file system format of your USB if you take your USB drive for multiple uses.

1. How do I make my flash drive compatible with Mac and PC?
To make your flash drive compatible with Mac and PC, you'll need to set the file system format to FAT32 instead of NTFS or APFS. FAT32 is compatible with both Windows and Mac computers.
2. Is exFAT compatible with Mac and Windows?
Yes, exFAT is compatible with both Mac and Windows computers. You can set this file system format to an external hard drive so as to use it for data transferring between Mac and Windows without any read or write issues.
3. Is FAT32 or exFAT better for Mac?
For data reading and writing speed, FAT32 and exFAT perform almost the same on Mac computers. The only difference is the limit of partition size on FAT32. When the storage capacity on your devices is 64GB or larger, you can only set it to exFAT on a Windows computer.
Fortunately, this limit doesn't exist on Mac computers. So you can use either FAT32 or exFAT on your devices for Mac usage.
