Received earlier than expected after call to the supplier. Easy to configure. Wifi works perfectly on 1 27p iMac, MacBook Pro 1, 1 MacBook Air former ... I am fully satisfied because it works ur legacy systems and Mavericks. I bought it because of its attractive price, replacing 2 Canon Pixma iP5200 printers for which Canon does not provide a driver for Mavericks and did not even make a gesture of goodwill for these two printers in perfect condition but obsolete ... Thanks Canon!
