klayout
KLayout is a free, open-source layout editor and viewer for microelectronic design, widely used by chip designers, semiconductor researchers, and academics. It supports viewing and editing GDS, OASIS, and other standard microelectronic layout formats. The application includes schematic editing, cell browsing, layer manipulation, and scripting capabilities via Python and Ruby. KLayout is particularly popular in academia and among smaller design houses as an alternative to expensive commercial tools like Cadence Virtuoso.

1 suggestionKLayout has no official native Apple Silicon build in its standard distribution. The project's lead developer has stated that pre-built binaries are Intel-only and recommended compiling from source for M-series Macs. However, KLayout currently runs acceptably under Rosetta 2, and users have confirmed success building native arm64 versions directly from the GitHub source code using Homebrew and the project's build4mac.py script — a process that takes approximately 12 minutes on typical hardware. Since Apple is removing Rosetta 2 in macOS 28 (September 2028), KLayout's Intel-only pre-built binaries will stop working at that point. If you wish to continue using KLayout after that date, you have two options: (1) contact the KLayout maintainers to ask about an official native build timeline, or (2) build it yourself from source now using the documented Homebrew method so you understand the process before the deadline. Compiling from source gives you the latest features immediately and ensures you will have a working native binary after Rosetta 2 is retired. For users who prefer not to compile, consider reaching out to the KLayout community forums or GitHub issues to express interest in an official native Apple Silicon binary.
