Hi there, I have an iMac 27" 5K (Mid 2015) mit 3,3 GHZ Intel Core i5 is has an Bad Logicboard … I can buy an working Logicboard from an Late 2015 iMac 27" 5K - without CPU So … does the Late 15 Logicboard fits in the Mid 2015 iMac ? Does also fit the i5 GPU in the Socket ?
Apple uses a base logic board in this series: iMac Intel 27" EMC 2806 Logic Board. But before you replace the logic board make sure your CPU is OK. IFIXIT doesn’t offer the newer Late 2015 - 2017 logic board.
