The Calculator app has been a part of macOS for a long time. It has four modes in macOS Sequoia. Apple’s Calculator app can be found in the /Applications folder at the root of your Startup Disk. It is one of the simplest macOS apps and was one of the first utilities included with Mac OS X in 2000. The original Mac also came with a basic Calculator app as a desk accessory.
The Calculator app has remained largely unchanged over the years with some minor cosmetic UI changes. In macOS Sequoia, the Calculator app has four modes: Basic, Scientific, Programmer, and Convert. You can switch between these modes by clicking the small calculator icon in the lower left corner of the app window.
Basic mode offers simple calculations, while Scientific mode provides a wider interface with standard scientific formula buttons. Programmer mode is tailored for programming calculations with features such as bitwise operators and hexadecimal display. Convert mode allows for currency conversions and other unit conversions.
The Calculator app also includes features like logical and bitwise operations, byte flipping, ASCII, Unicode, and display buttons. It offers a convenient history feature to view past calculations. The advanced features in macOS Sequoia’s Calculator app are beneficial for programmers and scientists.
For more detailed information, you can refer to the Calculator User Guide on the Apple website, although it may need to be expanded to provide more comprehensive information.
