Editing Carbon (API) (section)

===Deprecation and discontinuation===
In 2012, with the release of OS X 10.8 Mountain Lion, most Carbon APIs were considered deprecated. The APIs were still accessible to developers and all Carbon applications still ran, but the APIs would no longer be updated. On June 28, 2017, Apple announced that 32-bit software for macOS, such as all Carbon applications, would no longer be supported “without compromise” on versions of macOS after [[macOS High Sierra|macOS 10.13 High Sierra]].<ref>{{cite web|url=https://developer.apple.com/news/?id=06282017a|title=64-bit Requirement for Mac Apps|author=Apple Inc.|author-link=Apple Inc.|date=2017-06-28|access-date=2018-02-18|archive-url=https://web.archive.org/web/20180130123005/https://developer.apple.com/news/?id=06282017a|archive-date=2018-01-30}}</ref> [[macOS Catalina|macOS 10.15 Catalina]] officially removed support for 32-bit applications, including all Carbon applications.<ref>{{cite web|url=https://www.macrumors.com/guide/32-bit-mac-apps/|title=32-Bit Apps 'Not Optimized for Your Mac' to Stop Working on macOS Catalina|author=MacRumors|date=June 4, 2019|access-date=August 10, 2019}}</ref>
