We could only determine the WLAN performance in combination with a Linksys E4200 802.11n router. 3G / 4G or LTE is only available via Bluetooth, WLAN or USB Tethering (USB Tethering with Android only via third party drivers like HoRNDIS). Ethernet is only available with a USB or Thunderbolt adaptor. The MacBook Pro Retina only supports the wireless standards 802.11 b/g/n/ac (2.4 and 5 GHz) and Bluetooth 4.0. With the low weight and the thin case, the MacBook Pro 13 is clearly a subnotebook, but its powerful processor stands out from the competition in this class. Our review unit was not provided by Apple, we just bought it in the online store. Our review unit is the configuration with a Core i5-4258U processor, 256 GB SSD and 8 GB RAM. That is not a big difference to the 17 mm of the 13-inch MacBook Air, but the case does not get thinner towards the front. Apple was also able to reduce the thickness of the case from 19 mm to 18 mm thanks to the reduced energy consumption of the platform. The Haswell update of the 13-inch MacBook Pro Retina does not only include new components. For the original German review, see here.
