This installs SW Rack 1.0.0 for macOS 11 or later (Apple silicon and Intel):
SW Rack.component → /Library/Audio/Plug-Ins/Components/SW Rack.vst3 → /Library/Audio/Plug-Ins/VST3/Both formats are selected by default. An administrator password is required (system Library install location).
Before installing: quit all DAWs. This package does not install or remove the Signalwork Suite plugins (EQ, Comp, Color, De-Ess, Gate, Limit). Preferences are preserved.
Older copies: after the new system-Library bundle is confirmed present, the installer removes matching older system-Library Signalwork Rack.* for the same format, and matching user-Library SW Rack.* / Signalwork Rack.* for the same format only, so a leftover user copy cannot shadow the system install. Other plugins are never touched.
