No need. Byte ordering was historically different in the IBM vs Apple worlds, but all imaging software made even since quite a while ago is able to read both, and the headers in the TIFF file say which ordering is used. Unless you use an archaic program, or something extremely specialized, you can use either and it truly makes no difference. I just save without even looking at which option it's defaulted to. I'm sure from receiving many photo files from customers, I probably have quite a few of each in my system.
