M2 Macbook Air dual display possible with two older 27” Apple displays?

The M2 MacBook Air only supports one external display.

You can connect the Thunderbolt Display (using an Apple Thunderbolt 3-to-2 adapter), or the LED Cinema Display (using a USB-C to Mini DisplayPort adapter), but the M2 MacBook Air can only drive one of those displays. Even if there were Macs for which daisy-chaining the LED Cinema Display to the Thunderbolt Display might work, yours is not one of them.

Thank you very much for your detailed responses! Much appreciated. I'm a moron though: I remember now I have the 15" 2023 MacBook Air, not the 13"-- so have to revisit my research a bit.

The answers are the same for the MacBook Air (15-inch, M2, 2023) as for the MacBook Air (M2, 2022). It has the same chip (a plain M2 chip), and in this case, it's the chip (not the size of the built-in screen) that matters.

"Simultaneously supports full native resolution on the built-in display at 1 billion colors and:

• One external display with up to 6K resolution at 60Hz"

There are third-party workarounds, using DisplayLink and the like, that can let you drive extra monitors in a second-class way. Such workarounds would require installation of special driver software on your Mac, and may come with assorted compromises.

As far as I know, none provide Thunderbolt output. You'd need to hook up your Thunderbolt Display using hardware video output (and an Apple Thunderbolt 3-to-2 adapter), and your LED Cinema Display using something like:

• SonnetTech – USB 3 DisplayLink Dual 4K 60Hz DisplayPort Adapter or
• Plugable – Plugable USB-C or USB 3.0 to DisplayPort Adapter (UGA-DP-S)

These are "for examples", not recommendations.

With any DisplayLink-based product, you might need to visit the Synaptics site for drivers and support articles.

Note that despite the similar names, DisplayLink is not the same thing as DisplayPort (the video standard).
