Mac OS Extended (Journaled/HFS+): If you didn't update your Mac OS to High Sierra, the default file system on your Mac shoule be Mac OS Extended. Mac OS Extended (encrypted) would be an ideal option if you probably carry your laptop or external drive here and there. You can encrypt it so that no one can access the contents on your drive.
MS-DOS FAT (aka FAT32): In addition to Mac, it can also be written and read by Linux and Windows. It enables you to regularly share files with your friends who own a PC. Nevertheless, this older file system is limited to no more than 4GB and there might be security issue and disk errors.
ExFAT: It is similar to ExFAT which can be read by both Windows and Mac, but it can store more than 4GB files.

Summary :
Want to format an external hard drive for Mac and Windows PC? Do you know how to do this work easily? This MiniTool article will show you specific methods to make external hard drive compatible with Mac and PC, which are easy and safe to complete.
Quick Navigation :
As we know, external hard drives are widely used to backup data or interchange files among different computers. Well, is there an external hard drive that could be shared between Mac and Windows PC? Of course, there is. Actually, most external hard disks could be compatible with Mac and PC as long as you format them correctly.
Why Need to Format External Hard Drive for Mac and PC
To put it simply, if you want to share external hard drive between Mac and PC, you need to format an external hard drive for Mac and PC.
Currently, hard drives for Windows PC are always formatted with NTFS, while hard disks for Mac are formatted with HFS+. However, when we connect a NTFS formatted disk to Mac, Mac OS X doesn't allow us to write files to the drive neither edit files, though it can read a NTFS drive. Similarly, Windows OS will ask us to format the HFS+ formatted drive when we connecting such a disk, let along edit files saved on HFS+ formatted hard disks unless we resort to third party programs.
But luckily, there are file systems well supported by both Mac and Windows PC, and they are FAT32 (it might be called MS-DOS on Mac) and exFAT. As long as we format the external hard drive to one of these 2 file systems, it can be shared between Mac and Windows.
Further Reading
Both FAT32 and exFAT have advantages and disadvantages.
FAT32: FAT32 works with all versions of Windows, Mac OS, Linux, game consoles, etc.
However, single files on a FAT32 drive can't be larger than 4GB. If your external drive saves files larger than 4GB or you plan to save larger files to this drive, converting to FAT32 is not recommended.
In addition, a FAT32 partition must be not more than 32GB if you create it in Windows Disk Management. Of course, there is free partition manager that can help create a FAT32 volume up to 2TB, which also functions correctly.
exFAT: exFAT has very large file size and partition size limits, which means it's a good idea to format your external hard drive to exFAT.
Nevertheless, a lot of users complained that exFAT is slow, and they highly suggest using FAT32 if you can avoid file size constraints.
Three Options for Accessing NTFS Drives on Mac
Paid Third-Party Drivers
Some paid third-party NTFS drivers for Mac can be used to access NTFS drives on Mac. They work well and they have better performance than the free solutions which will be mentioned in the following part. Paragon NTFS for Mac is such a driver.
Besides, you can also use the paid third-party file system converters to convert NTFS to FAT32 or exFAT which are compatible with both Mac and PC. MiniTool Partition Wizard is one representative.
Free Third-Party Drivers
FUSE for macOS is a free and open-source NTFS driver that can enable write support. But, this solution is slower relatively. And the automatically mounting NTFS partitions in read-write mode can be a security risk for your Mac computer.
Apple’s Experimental NTFS-Write Support
The Mac OS has an experimental support for writing to NTFS drives. Usually, it is disabled by default and needs some messing around in the Mac terminal to enable it.
It doesn’t work properly all the time and could lead to potential issues with your NTFS file system. For example, it had corrupted data before. Thus, we don’t suggest using this tool and we believe it is disabled by this reason.
Here, we recommend using the paid third-party tools since they are easy-to-use and can do good work for you.
Then, we will introduce these three options for you in the following content.
The Best Paid Third-Party Driver: Paragon NTFS for Mac
Paragon NTFS for Mac can write, edit, delete, copy, or move files on NTFS volumes from your Mac computer. It offers a 10-day free trial. If you want to use it all the time, you need to pay for it.
With it, you don’t have to fiddle with terminal commands to mount partitions manually. Additionally, it can mount partitions automatically and safely. More importantly, it can code with the potential corruption. If you purchase a Seagate drive, you can even get a free download of Paragon NTFS for Mac.
All in all, it does its works well and gives you good user’s experience.
The Best Free Third-Party Drivers: FUSE for macOS
FUSE for macOS is a free solution to access NTFS on Mac. But it is less secure.
If you want to make automatically mount NTFS partitions in read-write mode on Mac, you need to temporarily disable the System Integrity Protection and replace one of Apple’s built-in tools with a binary that is more vulnerable to attack. Thus, your Mac is in danger when using this driver.
However, you can use it to manually mount NTFS partitions in read-write mode if you never mind using the Terminal. This will be safer, but you need to do more work. You can go to google the steps and see how complex they are.
Apple’s Experimental NTFS-Writing Support: Don’t Do This, Seriously
Although we mentioned this method in our article, we still don’t recommend it because it is the least tested. It is just for educational purposes, and it is available on Mac OS 10.12 Sierra. Perhaps, it will be unstable forever.
