This installs SW Delay 1.0.0 for macOS 11 or later (Apple silicon and Intel):
SW Delay.component to /Library/Audio/Plug-Ins/Components/SW Delay.vst3 to /Library/Audio/Plug-Ins/VST3/Both formats are selected by default. An administrator password is required (system Library install location).
Before installing: quit your DAW. This package does not install or remove SW Rack or the Signalwork Suite plugins. Your preferences, licenses and presets are preserved.
Older copies: after the new system-Library bundle is confirmed, an older SW Delay of the same format in your user Library is moved to ~/Library/Application Support/Signalwork/rollback/ so it cannot shadow the system install. Nothing is deleted, and other plugins are never touched.
