Your Mac is up to date – macOS Mojave 10.14.2 I knew this model would upgrade to the latest macOS (10.14.6). Redux: I'd bought a reconditioned MBA (11-inch, Early 2014) in excellent physical condition but with its macOS (10.14.2) in poor shape. I offer my own answer to report for others' benefit what finally worked for me. Success, but there are many gotchas and blind alleys on the way. But it would be nice to have Xcode on the MBA flash drive instead, even if it's a back version. Now when I look at Xcode on App Store the GET button is enabled. I've tried attaching an external USB drive and (discovering this link: -which fires up App Store showing Xcode 10.3) I can install Mojave 10.14.6 onto it, provided I reformat it as APFS, as the error messages instruct me. System Prefs tells me my software is up to date (at 10.14.2) BUT the latest Mojave is 10.14.6.Ĭan my MBA be fixed to upgrade to 10.14.6? If not (or too difficult) where can I get a back level of Xcode which will install under Mojave 10.14.2?īTW. Not surprisingly the 'GET' button is disabled in App Store. I want to install the latest Xcode 10.3, which says it needs macOS 10.14.3 or higher.
