Apple's AirPrint supports the Brother MFC-J995DN and J995DWN models without any Brother software or drivers installed. Visit System Preferences : Printers & Scanners panel. Right-click on your J995 device and choose Reset Print System… . This will ask for an admin password, and remove the device from that panel, and pop another panel showing that Apple's Bonjour service has detected the wired/wireless device.
Click on the Bonjour printer entry, and a re-add panel will appear displaying your last used Brother drivers. Ignore that, and on the selection, choose either the visible AirPrint, or auto-select which should also choose Air Print. Re-add the printer and make it your default device. Print something.
