How to check compatibility of macOS Sequoia on MacBook Air?

According to that Preview page, any MacBook Air whose hardware release date is 2020 or later will be able to run macOS Sequoia. I.e., Sequoia will support all of these MacBook Airs.

• MacBook Air (Retina, 13-inch, 2020) – the last Intel-based model
• MacBook Air (M1, 2020)
• MacBook Air (M2, 2022)
• MacBook Air (15-inch, M2, 2023)
• MacBook Air (13-inch, M2, 2024)
• MacBook Air (15-inch, M3, 2024)

The M2 and M3 MacBook Airs have several significant advantages over the M1 models.

• They have MagSafe 3 charging ports. Since there are only two multi-purpose USB-C / Thunderbolt ports, the ability to charge either over USB-C or over MagSage 3 may help in juggling peripherals and ports.
• They have better sound systems.
• If you need 24 GB of RAM, you can get them with 24 GB of RAM. (Note: RAM is non-expandable in all of the machines listed here.)
• They're further away from the date when Apple will consider them vintage or obsolete for repair purposes.
• You can get M3 MacBook Airs in 13" or 15" sizes, and once had the same choice for M2 MacBook Airs. M1 MacBook Airs came in any size you wanted as long as that size was 13".

The M3 MacBook Airs have a couple of other enhancements.

• The M3's GPU has hardware-accelerated ray tracing, which might be useful for gaming.
• The M3 MacBook Airs can drive two monitors when the lid is closed (and only when it is closed). The second monitor has a lower resolution limit – so if it is a 4K monitor, you won't see any settings between Retina "looks like 2560x1440" mode and native 3840x2160 mode. (If you want a Mac notebook that can drive two external displays with the lid open, you need a MacBook Pro with a 'Pro' or 'Max' chip.)

The problem is after watching Apple's WWDC 2024 for macOS Sequoia and looking at the website it says it only supports the M1 MacBook Air.

Nope. That’s not what it says.

Sequoia supports the M1 MacBook Air and later. You should purchase the most recent model you can afford.

You should purchase the most recent model you can afford.

i would suggest try for an m3 air if you can afford it because of the ssd speeds. if you dont care about that get an m2. if you dont care about a device being previously owned, then get an m1 air
