As answered by people managing JavaScript Operator Lookup and MacCove.
MacCove's answer:
Swift, built as a native macOS app.
MacCove's answer:
Professionals who have spent years on Windows Excel and recently switched to a Mac, especially heavy keyboard-driven users such as analysts, finance professionals, and administrative staff.
MacCove's answer:
It lets Mac users keep using the Windows-style Excel keyboard shortcuts they already know, like Alt+E+S+V for Paste Special, instead of relearning new ones. It runs natively and locally on macOS with zero data collection.
MacCove's answer:
It preserves years of built-up Excel muscle memory instead of forcing users to learn a new shortcut system, is local-first and privacy-focused with no tracking or data leaving the device, and is Apple-notarized, with a free trial and affordable paid tiers.
MacCove's answer:
The team noticed that switching to a Mac is easy, but leaving behind years of Excel keyboard muscle memory is not, since every small shortcut interruption adds up over a workday. MacCove was built to map familiar Windows Excel shortcuts directly onto Mac so existing habits keep working.
