Installing AD-1 — Tsukuba Onkyo

AD-1 carries no Apple developer signature. Because of that, macOS marks the downloaded files as quarantined. While that flag is set, your DAW will not load the plug-in. To install it, the flag has to be cleared.

The bundled install.command does that for you. But since the operation amounts to stripping a security attribute from software of unverified origin, what the script does is written out below. Please read it before running it.

Steps

Get the zip from the download page and unpack it
Double-click install.command inside the folder that appears
Terminal opens, shows what will be installed, and waits. Press Enter to go ahead, or control+C to stop
Quit your DAW completely, then open it again

If you see “cannot be opened because the developer cannot be verified”. That is because install.command itself is quarantined too. control-click the file and choose Open; the same dialog then gains an Open button.

What install.command does

It does exactly three things. No administrator password is required, because it writes only into your own user area (~/Library), never /Library.

Copy. It puts the .component and .clap from the same folder into the fixed location for each format
```
~/Library/Audio/Plug-Ins/Components/   Audio Unit
~/Library/Audio/Plug-Ins/CLAP/         CLAP
```
Clear the quarantine flag, on what it just installed only.
```
xattr -dr com.apple.quarantine <installed bundle>
```
It does not touch any other file. Nor does it disable Gatekeeper system-wide (spctl --master-disable is not something it does).
Make macOS rebuild the Audio Unit registry. It runs killall -9 AudioComponentRegistrar and waits up to 60 seconds for the plug-in to appear in the list. Open Logic without that wait and it may tell you the component cannot be found

Doing it by hand

If you would rather not run the script, you can do the same by hand. Copy the bundles into the two folders above, then run the following for each format you installed.

xattr -dr com.apple.quarantine ~/Library/Audio/Plug-Ins/Components/"Akadem Drive AD-1.component"
xattr -dr com.apple.quarantine ~/Library/Audio/Plug-Ins/CLAP/"Akadem Drive AD-1.clap"

You can check whether the flag is still set with the following. No output means it has been cleared.

xattr -r -p com.apple.quarantine ~/Library/Audio/Plug-Ins/CLAP/"Akadem Drive AD-1.clap"

~/Library is hidden in the Finder. Open the Go menu and hold option, and Library appears.

Why there is no signature

A Developer ID certificate is only issued to members of the Apple Developer Program, which costs $99 a year. AD-1 is given away, so that cost has not been taken on yet.

Any paid product will be signed and notarised, without exception. Being asked, right after paying, to run a script that strips a security attribute on behalf of a developer you cannot identify is not an experience worth selling.

If that is not acceptable to you, please do not install it. Asking anyone to strip a security attribute from software of unverified origin is not, in itself, a good thing to do. We would rather you passed on it than installed it uneasy.

Uninstalling

Double-click uninstall.command in the download. It simply removes what is at the two paths above. Your settings live inside your host's project files, so nothing is left behind on the plug-in side.
