Open in new tabDownload PDFAbout this MacBook Air 13-inch Retina A2179 (2018–2020) (820-01958) board
This page is generated from the board file itself, so the map above is the manufacturer layout rather than a redrawing of it. The board carries 3,456 components and 2,199 named nets across 12,294 pads, with 747 test and probe points marked in amber for when you want to measure rather than desolder. About 100% of the components are surface-mount, so the top and bottom side filter is usually the difference between finding a part in one pass and searching both faces.
The schematic is 86 pages and covers the usual blocks you would expect on a board this size — input power, PPBUS/G3 hot, rails, clock, storage, display and audio output. The page index under the viewer gives you the heading on each sheet, so you can jump straight to the block you are chasing instead of scrolling.
This is the logic board fitted to the A2179 (2018 – 2020), covering the 2018–2020 production run. Check the board number before you order parts: several of these machines shipped with more than one board revision, and a component taken off the wrong revision frequently has the same designator and a different footprint.
Frequently asked about the MacBook Air 13-inch Retina A2179 (2018–2020) (820-01958)
What board number is the MacBook Air 13-inch Retina A2179 (2018–2020) (820-01958)?
The MacBook Air 13-inch Retina A2179 (2018–2020) (820-01958) uses logic board 820-01958, the board fitted to the A2179. There is more than one revision of some of these boards, so check the number on the board itself against the one on this page before you order a part — a component from a different revision will often not fit or will not reference the same nets.
How many components and nets are on the MacBook Air 13-inch Retina A2179 (2018–2020) (820-01958)?
The board file records 3,456 components (3,445 surface-mount, 11 through-hole), 2,199 named nets and 12,294 pads, plus 747 test and probe points. The board measures 181 × 44.98 mm. Roughly 100% of the parts are surface-mount, which is why the top and bottom side filter matters — a lot of this board is only reachable from one face.
How do I use this MacBook Air 13-inch Retina A2179 (2018–2020) (820-01958) boardview?
Type a designator such as a component reference, or a net name, into the search box above. A net name takes priority and highlights every pad on that net across the whole board. Clicking a component outlines it in white and lists every pad it has with the net each one belongs to; clicking one of those nets jumps the highlight to the whole rail. Use the side filter to isolate the top or bottom face, and the designator toggle to hide the reference text when you are zoomed out.
Does the MacBook Air 13-inch Retina A2179 (2018–2020) (820-01958) come with a schematic?
Yes — the full 86-page schematic is embedded above and downloadable as a 5.2 MB PDF. The page index under the viewer lists the page headings so you can jump to a circuit rather than scrolling through every page. The schematic's text layer is also published as text on this page, which means you can search it with Ctrl+F on any browser, including the ones where a PDF in a frame refuses to be searched.
Can I download the MacBook Air 13-inch Retina A2179 (2018–2020) (820-01958) boardview file?
Yes. The original 603 KB BoardView file is linked below under downloads, named macbook-air-13-inch-retina-a2179-820-01958.brd. Open it in BoardViewer or any other tool that reads the .brd format. The interactive viewer on this page is for looking things up quickly; the .brd is what you want when you are at the bench with the board on the mat.
Schematic text — searchable without opening the PDF
A PDF inside a frame is invisible to a crawler and often unsearchable in the browser. Here is the schematic’s text layer as plain text, so you can use Ctrl+F on this page to find a rail name, a component reference or a page heading.
