Have you encounterd this situation unluckily?

One day,you are extremely interested in a good project from others and upload that into your usb , get ready to learn it well after you are back home.In the evening ,you are free and insert pendrive into apple pc,what happened ? there is nothing shown on screen.Well,take usb out of there,and try again ,still nothing is there.You are rushed to ask google for reason.............

The fact is the content of the USB memory stick is full, it is unrecognizable to plug in the MAC system. This is not a quality issue and allows customers to try to delete some and try again. Because the Apple system writes some os auxiliary files into it when reading the external storage,

The files and caches written by the Apple system depend on the size and type of files in the USB flash drive. In short, the use of U disk on Apple computers requires cache space and cannot be copied.

 If the disk format of the U disk / removable hard disk is NTFS, and the Mac operating system does not support the disk of this format, the file cannot be written. Customers need to manually change the U disk format to: FAT / FAT32 / EXFAT format

Note the factory default format of U disk: below 2G: FAT 4G-32G: FAT32 64G: EXFAT

If a customer specifically requests the NTFS format, the customer needs to be informed that the format does not support the Apple system. If the customer changes the U disk format or mass production can not be deleted or quality problems caused by other programs, our company does not guarantee

FAT FAT32 does not support copying of a single file larger than 4G

EXFAT NTFS supports a single file greater than 4G

Note the factory default format of U disk:

Below 2G: FAT

4G-32G: FAT32

64G: EXFAT

128G: EXFAT

Now,you are supposed to be more familiar with your favourite usb.
