If Apple (AAPL) does release its next-generation MacBooks this spring, it seems they’ll come with super-fast Wi-Fi capabilities. 9to5Mac reports that the latest version of OS X that Apple seeded to developers this week contains code supporting the 802.11ac standard, also known as “5G Wi-Fi,” that is capable of delivering theoretical peak speeds of 1.3Gbps and is a major step forward in the evolution of Wi-Fi. The added code confirms a report from earlier this year about Apple and Broadcom (BRCM) teaming up to bring gigabit-speed 802.11ac chips to the 2013 Mac lineup. Asus (2357) became the first company to produce a notebook with 802.11ac connectivity last year with its G75VW gaming laptop.
