Currently the only way to utilize the "John Deere Data Manager", which is a windows program used to upload data off of thumb drive or memory card, is to install it on a windows operating system, dual boot your mac, or use client virtualization. 

As for using the online MyJohnDeere and Operations Center, it will work well with the exception of printing. I have found that printing on certain macs distorts some of the data. This is due to the MacOS encoding process when they take website data and convert it into a printable .pdf. The only solution I have found is to change paper type to A4.
