Excel for Mac where is Trust Center

Using Excel on a Mac to catalogue photos.   Have cells (lots of them) with hyperlinks to

individual photos stored on the Mac. Every time I try and open a hyperlink I am

asked to "grant access" to the file. 

If I was using a Windows version of Excel the solution would be to go to

the File-Options-Trust Center and enable accessing the file (without being

requested to "grant access") 

Alas, I cannot find Options-Trust Center in the Mac version of

Excel.  Where is it? If it does not exist,

is there another way to solve the problem?
