Tested on a MacBookPro using Nadia, MATE Edition.
When I install LinuxMint, the ethernet works fine but I can't use the wireless. To use it, I have just to open source software and enable the proprietary wireless driver (in my case it's "Broadcom 802.11 Linux STA Driver from bcmwl-kernel-source").
The problem is I need to be connected (so I must have ethernet connection) to enable it (because it's being downloaded), and this is so unconfortable if you have no possibility to ethernet connection (e.g. I'm a student and here at university there is wireless access only).
I strongly suggest to include the wireless driver for all laptops in each Mint release, they are no so big.
