Apple Obsoletes Mid 2010 15-Inch and 17-Inch MacBook Pros
The older notebooks and server rack hardware are now classified as vintage in the United States and Turkey, and obsolete in the rest of the world, according to Apple.
Macs and other products on the vintage and obsolete list are generally no longer eligible for hardware service, but OS X El Capitan still supports many older Macs back to Mid 2007. Apple defines vintage products as those that have not been manufactured for more than five but less than seven years.
The new additions come less than three months after Apple obsoleted select early 2008 to late 2009 Macs, including the iMac (21.5-inch, Late 2009), iMac (27-inch, Late 2009), MacBook Air (Mid 2009), Mac Pro (Early 2009), MacBook (13-inch, Early 2008), MacBook Pro (15-inch, Early 2008), and MacBook Pro (17-inch, Early 2008).
The MacBook Pro models obsoleted today were originally announced on April 13, 2010. Read how to identify your MacBook Pro model.
