In macOS, when trying to execute built 4D applications, users may encounter the following errors:

- Can't find form "ErrorRuntime". 4D Resources are probably wrong.

- Error code: 3588 (COCO). The operation couldn't be completed. (Cocoa error 3588.)

- Error code: 1010 (xbox). Failed to load library [...]WebViewerCEF.bundle

These errors are usually caused by wrongly copying 4D application files from one location to another, especially over the network.

The solution to this problem is compressing the application files (as .zip, or .rar) before transfer.
