G Tech mobile SSD need to reformat on a Mac

G Tech mobile SSD I need to reformat on a Mac to a format that can be can be read and write to on both Mac and intell PC.
If this is not possible I am looking for other solutions.

Try Installing NTFS for Mac or any other similar software on your Mac machine.
It will allow you to read/write data on your SSD.
No need to reformat it.
