Arc 1.4.1
Arc 1.4.1 includes an update to license activation on Mac.
Previous release
License activation update for Mac
Windows 10/11 (64-bit), or macOS 11+ on Apple Silicon.
Highlights
- Arc now ships its own certificate trust store, so secure connections to the license server work on a fresh machine without extra setup.
Fixes and refinements
- Activation on macOS no longer fails with “could not reach the license server” on a healthy connection, and a genuine certificate problem now reports itself clearly with the exact next step.
System requirements
Windows 10/11 (64-bit), or macOS 11+ on Apple Silicon.
