Short answer: download 'Airdroid' app onto your phone to wirelessly transfer data and control your phone.
The solution is in more detail below.
Hope it helps
I've had this problem repeat itself with changing Mac osd and with android firmware updates. There is a free Android App in PlayStore called, 'Airdroid'. I found the basic version brilliant and intend to buy the pro version in gratitude.
Download the app, create an account and sign in.
Airdroid will open on your phone with instructions to open http//web.airdroid.com on the Mac/pc. Here on this site, on your Mac, you can sign-in or more simply scan the displayed 'QR' symbol with your phone by pressing 'scan QR'. The page will then change to a file tree view of your phone.
This will enable up/down loading of files/pics/videos, texting... view contact listings, remote find phone with gps, change lock codes, wipe phone....
