Because of the unique design of the MacBook Air, MacBook Pro and iMac, these particular models have, in the past, not been able to attach mobile privacy filters to protect sensitive on-screen data from peering eyes. 3M has changed that with its Mac Confidential privacy filters (http://macte.ch/BzBWB).
3M — yep, that 3M, the company that specializes in adhesives through their iconic Scotch Tape brand, has created three new designs of privacy filters specifically for these devises. The filters use a clear, adhesive strip to attach a privacy filter that doesn’t detract from the Mac’s aesthetic and can be repositioned hundreds of times. Depending on monitor size, they range in price from US$33 to $134.
