[Spanish, saw, sierra, from Latin serra, saw.]
si·er′ran adj.Word History: In English, the word sierra is probably best known for the names of certain mountain ranges, such as the Sierra Nevada (in Spanish, the "snowy sierra") of Spain, the similarly named Sierra Nevada of Eastern California, and the Sierra Madre (the "mother sierra") of Mexico. The English word sierra, "rugged range of mountains having an irregular or jagged profile," is a borrowing of Spanish sierra. In Spanish, sierra literally means "saw," but the word is also used in the extended meaning "line or group of mountains with a jagged profile." As a further example of how a word meaning "saw" can become a word meaning "mountain range," we need only mention the Sawtooth Mountains of central Idaho.sierra (sɪˈɛərə) n (Physical Geography) a range of mountains with jagged peaks, esp in Spain or America[C17: from Spanish, literally: saw, from Latin serra; see serrate] siˈerran adj

http://sierra.com /.SierraVersion 10.12 of the Mac operating system. Introduced in 2016, Sierra was officially rebranded macOS Sierra and not OS X Sierra (the OS X moniker was used by Apple for 17 years). Sierra is not supported on older Macs, although it may run depending on the model. The official support is for Mac computers built in 2010 or later, except MacBooks and iMacs, which can be 2009 or later.
More Integration of Mobile Features
Siri is integrated into Sierra, and an Apple smartwatch can be used to unlock the machine. iCloud files can be accessed via the Mac as well as mobile devices, and user files are uploaded to iCloud if local storage becomes insufficient. The Photos and iTunes apps have been enhanced. For better support of solid state drives (SSDs), a new file system is used in Sierra (see APFS). Picture-in-picture allows a video to appear over a full-screen application, and the clipboard can be shared across other Macs in the network. See Mac OS X and High Sierra.MedicalSeeSIRISIERRA
