The 'Mid-2012' Retina Display MacBook Pro models can be identified externally by a unique EMC number- 2512- as well as the serial number. So even if I change to Macbook Air 2017 the differences in speed and multi-tasking capabilities wouldn't be significant. The regular 'Mid-2012' MacBook Pro models only can be externally differentiated by the serial number courtesy of s Ultimate Mac Lookup feature or the the EveryMac app. If that's your thing go for it, otherwise it's pointless. The only upgrade you will get is the battery life on the Air is insane due to the low powered SSD/CPU and RAM. The 2012 i5 is 3210M and the 2017 Air comes with i5-5350U assuming you will get the cheaper one and not the i7.Īccording to PassMark the 5350 scores lower than the 3210. In terms of the performance difference, the MacBook Air SSD is faster but you will hardly notice the difference in normal workload. The 2015 air is exactly the same laptop as 2013 air but with upgraded RAM and CPU. The 2017 Air is exactly the same laptop as 2015 but with upgraded CPU. This model is more like an iPad with an embedded keyboard than a laptop. No upgrade, no data if something happens. If you are unlucky enough for it to fail after apple's keyboard service program ends you will pay for the replacement.Īlso, the 2018 Air is with soldered on SSD. All MacBooks after 2016 excluding the Air 2017 are with terrible keyboards that WILL fail.
