If all goes according to plan, consumers could get their hands on a 5G-enabled MacBook in the second half of 2020. Apple's 2020 iPhone will also reportedly feature 5G, though not the company's rumored custom chip. That's said to arrive in 2021.
In the report, DigiTimes claims Apple will use ceramic for its 5G antenna board, rather than metal, which will apparently improve cellular reception and transmission speed.
"It is reported that the ceramic antenna board used by Apple has twice the transmission and reception efficient of the 5G signal to the metal material antenna board, but the cost is six times that of the metal material antenna board," DigiTimes said in its report.

Unfortunately, the use of ceramic might be an expensive choice, as the report claims that this material might incur six times as much manufacturing costs as opposed to incorporating typical metal-based components. This move might mean customers will have to pay a hefty premium to own the first crop of 5G MacBooks and given that the current models are already expensive, we’ll have to wait and see how the macOS-user camp feels when Apple unveils the pricing in the future.

The newly-designed 16-inch MacBook Pro is rumored to cost upwards of $3000, which can give you a brief idea of how much might Apple might charge for a 5G MacBook. However, the inclusion of a scissor-switch keyboard design might bring down the retail price. Since DigiTimes is the only one reporting about these machines, it’s best to treat the report with a pinch of salt, for now.
