System requirements

macOS

Solidly requires macOS 26 Tahoe or later.

Supported releases are macOS 26 Tahoe and macOS 27 Golden Gate.

Hardware

Solidly requires a Mac with Apple silicon. The application is built for arm64 only and does not run on Intel Macs.

Internet connection

The direct download needs an internet connection to sign in, to start the free trial, and to buy Solidly. After that, it confirms the Solidly account at least once every seven days, and it can be used without a connection between confirmations. See Connecting to the internet.

The Mac App Store build needs a connection to the App Store to start the free trial, to buy Solidly, and to restore purchases.

Memory

There is no fixed memory requirement. The amount of memory installed determines how large a model Solidly will attempt to load; see Advanced settings.
