New discoveries found in macOS 26.3 indicate several new Apple hardware products are on the horizon. In anticipation of Apple’s special “experience” on March 4, there are fresh references to two new models of the Studio Display, along with the frequently speculated low-cost MacBook featuring the A18 Pro chip.
### Are new Mac external displays on the way?
The references were discovered this week by Macworld within kernel extensions (kexts) in the public release of macOS 26.3 issued last week. These files mention three unreleased identifiers for Apple products: J700, J427, and J527.
J700, as earlier reported, is the codename for Apple’s anticipated low-cost MacBook equipped with the A18 Pro. This laptop is expected to debut next month, showcasing a display smaller than 13 inches. Bloomberg has also indicated that it will be constructed from aluminum and that Apple has experimented with various vibrant colors, such as light yellow, light green, blue, pink, classic silver, and dark gray.
However, what might be even more intriguing are the identifiers J427 and J527. The distinctions between these two models remain uncertain, but Macworld speculates they could either represent a larger screen size variant or a more budget-friendly version with fewer features.
Nonetheless, this isn’t the first instance revealing these two model identifiers. Bloomberg referred to these model numbers back in March. Here are the two scenarios Mark Gurman presented at that time:
> Apple is creating both and will select one for launch, or it’s a second model with an alternative screen size or specification set. After all, the Pro Display XDR is becoming a bit outdated too, so replacing that model could be logical.
Currently, Apple offers two external displays, including the Studio Display (starting at $1599) and the Pro Display XDR (starting at $4999). The Studio Display debuted in 2022 alongside the Mac Studio, while the Pro Display XDR was introduced in 2019 with the Mac Pro.
The inclusion of both external displays in macOS 26.3 suggests they are separate products still under development. Whether Apple intends to unveil both remains uncertain. We should receive more information shortly, with Apple expected to announce several new products during the week of March 2.
