Bulk PDF rename - Grant Access (MAC)

Hello,

I've created a macro to rename all PDFs in a single folder. Anytime I add a new files and run the macro, I have to grant access for the new files. Creating this macro to rename 500+ PDFs so I don't want to manually grant access every time I need to do this exercise. I'm having trouble with GrantAccessToMultipleFiles command. Not even sure if this is the correct route to take. Any advice? Thanks!
