Here’s so I did several times on a past job:
My work machine was a windows machine, so I formatted my portable drive to NTFS, which allowed the Windows machine to consolidate media to that drive.
I then purchased a copy of Tuxera, which will allow your mac to read/write to that NTFS formatted portable drive.
The only catch was that my Avid project/bins had to exist on a mac formatted drive. So, I simply copied the project/bins to my mac desktop, while leaving all the Avid MediaFiles on the NTFS drive. Worked very well.
