Format Drive For Mac
Format external drives to Mac OS Extended before using with Aperture Tips on preparing a new external hard drive for use with Aperture. You may wish to use an external FireWire or USB hard drive to store your Aperture Library, referenced images, or Vaults. Fortunately, there is a file system (actually two, I'll explain) that you can format your flash drive in order to be fully compatible with Mac and PC. In other words, you can access the drive and transfer data without any hassles.
If your Mac is running macOS High Sierra or later, you have two options for file formats: APFS and Mac OS Extended. Which should you choose? The key point is that disks formatted as APFS won’t be recognized by Macs running versions of macOS older than High Sierra. So if you think you might need to plug the USB drive into a Mac running an older version of macOS, format it as Mac OS Extended. APFS is optimized for SSD (solid state drive) such as flash drives, so if you reformat a flash drive on a Mac, you should definitely choose APFS (unless you plan to use it with a pre-High Sierra Mac, of course). Even on hard drives, however, APFS is faster and more reliable than Mac OS Extended. Finally, if you plan to use the USB drive as a destination for Time Machine backups, choose Mac OS Extended.

Avoid the Mac-only Apple Partition Map (APM) scheme. Click the “Erase” button when you’re done and Disk Utility will format your disk with the settings you specified. This will erase all the files on the drive! You’re now done–be sure to eject the disk before you remove it from your Mac. You can do this by clicking the eject icon to the right of the disk in the Finder or Disk Utility windows. You can also right-click or Option-click the drive in Finder or on your desktop and select the “Eject” option. Macs do have some limited support for other file systems–for example, Macs can read files on Windows-formatted NTFS volumes, but.
Once done with this process, the remaining space will display as unallocated space. Now, create another New Simple Volume in the remaining unallocated space for the next partition.
Name the hard drive. Select exFAT (or FAT for FAT32). Naming and Labelling Hard Drives If you will be using multiple external hard drives on a project, you’ll want to make sure to keep them organized. This includes the way you name the drive and how you label it. One of my personal tricks is naming all drives after an actor. For instance, one project had several external drives, all of which were named after different characters — Mugatu, Megamind, Lord Business, and Ron Burgundy.

The other limitation is the total size of the partition. If you format your FAT32 drive in Windows, the drive partition cannot be larger than 32GB. If you format it from a Mac running 10.7 Lion, the drive partition can be up to 2TB. Much better, except for that pesky 4GB limit. ExFAT The exFAT file system eliminates the two major deficiencies of FAT32: the largest partition and file sizes it supports are virtually unlimited by today’s standards.
How to format a USB drive to FAT32 on a Mac The main reason for formatting a USB drive as Fat32 on a Mac is that you want to be able to use the drive on a Windows PC, as well as a Mac — perhaps to transfer files between the two machines. You may also be preparing the drive for use as, say, a storage device for a media player or to record TV programmes on a TV with a USB port. 
The fact that Fat32 can be read from and written to on both Mac and Windows makes it very versatile. However, there is a significant limitation — individual files have a maximum size of 4GB. So, if you’re using the USB drive to store large video files, you may run into trouble.
