AppleInsider scored a leaked list of part numbers for new Apple hardware and it looks as though Apple is preparing a big refresh for the bulk of its Mac lineup. AppleInsider’s Neil Hughes speculates that the parts could mean as many as “14 new Mac models” arriving at Apple’s WWDC next week, which would represent a truly massive overhaul. Included on the list were parts for new versions of the MacBook Pro, the iMac 21.5, the iMac 27, the MacBook Air and the Mac Pro. 9to5Mac’s Seth Weintraub, who also received a copy of the list, speculated that there would be three new Mac Pros released: an entry-level Mac Pro for $2,999.00, a server Mac Pro for $4,599.00 and a high-end Mac Pro for $3599.00. No new Macs have been confirmed at this point, however, so we’ll likely have to wait for WWDC next week to see exactly what Apple has in store.
