MacBook Air (13-inch, Early 2015)
No longer receiving security updates
The newest macOS this device can run is macOS Monterey (12).
macOS Monterey (12) last got a security update on 29 July 2024. (799 days without a security update)
If your Mac runs an older version, this does not apply to you. Upgrading to macOS Monterey (12) is free and is what this status assumes.
What we do and do not know about a Mac
For an iPhone, Apple names the device in the advisory. For a Mac it does not: it only says "Available for: macOS Tahoe". So we do not know that this Mac got a patch, but that a patch exists for the newest macOS it can run. That is a weaker statement and we keep it that way here.
According to Apple it also runs: macOS Big Sur (11).
