The roll and the crossing
The roll is a mark for every app and add-on; the crossing shows which carry on past the macOS 28 line and which stop at it.
The Overview shows your Mac two ways under the answer.
The roll
One mark for every app, A to Z, then one for every add-on. Most are short and quiet: they run natively. The few that need you stand tall.
- A short mark: runs natively.
- A tall mark: stops after macOS 27, or a game that may.
- A short mark with a tall part: the app opens, but parts of it stop.
- An outline: already can’t open.
- A dashed outline: Vernacular couldn’t read it.
Hold the pointer over a mark to see its name and verdict. Click it to open that app or add-on.
The crossing
A line for now, on macOS 27, and a dashed line for macOS 28.
- One thick band holds everything that runs natively, with how many apps and add-ons it is, “Carry on.” and See all apps.
- Below it, a lane for each thing that needs you, and for each that already can’t open. A lane that stops at the dashed line stops working in macOS 28. A lane that carries on with a mark at the line opens, but some of its parts stop there.
Each lane has a short note, such as “Stops: Intel only.” or “Opens. Its login helper and Share extension stop here.”, and a button: Open Wayfarer for an app, See the parts, Show the driver, Show the plug-in, Show it or Show in Finder.
The macOS 28 line
The line is where Apple’s change to Rosetta begins. Vernacular never gives a date for it: it quotes Apple instead. At the foot of the page: “Apple says Rosetta stays a general tool through macOS 27, and from macOS 28 runs only certain older games.” Apple’s own words on Rosetta
