macOS Security is not letting Aeolus VST3 through

[AlexEddington]

Hello! I just discovered Aeolus and I love it.

However I'm trying to use the VST3 it in music notation apps (Dorico) but when the app scans plug-ins, it is blocked by OS Security.

Usually I can open System Preferences / Security and then click "open anyway". That option is given, but it doesn't work.

I have tried with older versions of Aeolus.vst3. No luck.

I have also tried following these instructions (from the Dorico team). No luck.

In a Terminal window, type:

sudo xattr -d com.apple.quarantine

followed by a space. Don’t press Return!

Then drag the plug-in onto the Terminal window. Now press Return.

You will asked to type in your admin user password.

Also worth noting that my older MacBook Pro (2014) running Big Sur could not open Aeolus Standalone 0.2.0 but does open earlier versions.

Thank you for your help with this!

Hi, glad you like the project!

As for your issue, both standalone and VST3 should run on macOS, Intel and Silicon (I've just checked on Intel mac running macOS Ventura and M1 macBook to be extra sure).

Could you please check that:

• You are not using a multibus variant of the plugin.
• You unpack and copy the Aeolus.vst3 to ~Library/Audio/Plug-Ins/VST3 folder on your mac.
• When you first download and unzip the plugin it will be indeed quarantined. Please check that you have removed the quarantine flag (run xattr Aeolus.vst3 from within the plugin folder in the Terminal).
• If you do see quarantine attribute, please remove it by running xattr -r -d Aeolus.vst3.
• Rescan the plugins once again after removing the quarantine flag (most hosts will blacklist plugins they failed to load so you need to force them to rescan).
• Do you have any VST3-able DAW you could try (e.g. Reaper)?
• Could you use AU plugin instead of VST3?

Earlier versions (around 0.1.8) were built on a very old system (macBook from 2008), which may explain why you could run them versions on your 2014 mac. Could you tell me which latest version does actually run on your older mac?

Could you please check that: - You are not using a multibus variant of the plugin. I downloaded this initially, but deleted and downloaded the correct

version after first failure to load.

- You unpack and copy the Aeolus.vst3 to ~Library/Audio/Plug-Ins/VST3 folder on your mac. Yes - When you first download and unzip the plugin it will be indeed quarantined. Please check that you have removed the quarantine flag (run xattr Aeolus.vst3 from within the plugin folder in the Terminal). - If you do see quarantine attribute, please remove it by running xattr -r -d Aeolus.vst3. I did these things (it couldn't find the file unless I gave the full

folder path), but it did not work. After the second command (removing quarantine) Terminal gave no reply, just a new prompt.

- Rescan the plugins once again after removing the quarantine flag (most hosts will blacklist plugins they failed to load so you need to force them to rescan). Dorico scanned again. Same problem - I can't get it past Security ("Open

Anyway" doesn't work)

- Do you have any VST3-able DAW you could try (e.g. Reaper)? Best I've got is Audacity. And no luck.

I'll try VCV Rack ...

- Could you use AU plugin instead of VST3? Not in Dorico, sadly. Earlier versions (around 0.8.x) were built on a very old system (macBook from 2008), which may explain why you could run them versions on your 2014 mac. Could you tell me which latest version does actually run on your older mac?

The latest standalone version that runs on my Mac is 0.1.12. Thank you for your help! Alex

FYI - I tried opening the VST3 in Max 8. Again no luck. Whereas the Audio Unit version opens.

If you still see the security warning, this means the plugin is still quarantined. Please make sure that xattr does not show any flags after clearing the file:

Version 0.1.12 was the last compiled on macOS 10.11 (El Capitan) all further versions were compiled for the latest macOS.
I can provide you with an ad-hoc build if you still want to run the latest Aeolus on Big Sur.

BTW Audacity can only load effect plugins, it won't show instrument plugins. You may try with Reaper (it is very small to download and try: https://www.reaper.fm/download.php)

It's working! I hadn't been using the correct syntax to remove the quarantine attribute in Terminal. Thank you for your help!

Oh, great then! Enjoy.

thanks it worked for me too on MacOS Ventura 13.6.1
