Making unison ignore file property differences

I use unison (the GUI) to synchronize two folders; unfortunately, one of them is a Windows drive mountpoint with properties set to 0777 - and unison shows that as a difference which requires synchronization.

How can I make unison (specifically, the GUI) ignore these property differences and only look at the rest of the criteria (dates, sizes etc.?)

Solution 1:

As indicated in the Preferences section of the Unison User Manual and Reference Guide, you can set:

perms=0
dontchmod=true

in your preferences file (.prf).

On a computer running OS X, you can find these .prf-files in the directory /Users/username/Library/Application Support/Unison/
