Before performing a new clean installation, I suggest you that to do a clean uninstall for both A.N.A and A.N.A 2 DEMO from your MAC, afterward you can also upgrade your macOS to 10.13.5 (17F77) which was released a few days ago.
Even if it should not be related to your macOS version, this could help with things like files permission under macOS.
Next to that are you using capitals letters or special characters in your macOSX HDD name ?? Or do you know if your macOS HDD is using a "case sensitive" format option ( you can check this with Disk Utility / get Info ).
Ok let's go for clean uninstall & install :
Clean Uninstall :
You need to delete all these files :
ANA plugins :
ANA 2 plugins :
Assuming you don't have Kick or Kick 2 installed, delete the folder Sonic Academy
yourmacHDD/Library/Application Support/Sonic Academy
Browse to yourmacHDD/Users/yourUSerName/Library/Preferences/ and delete any Sonic Academy folder if you have one as well as any file starting with com.sonicacademy.
( if your user library is not shown by default under your system please refer to this : Use “Go To Folder” and Open ~/Library/ Directly. All you need to do is hit Command+Shift+G from the Mac desktop (or Finder > Go > Go to Folder) and type in ~/Library to temporarily access the Library directory in the Finder.
Once you've perform all of the above, you should be good with the clean uninstall process.
Then I suggest you to reboot your Mac and to upgrade to 10.3.5
* Also check the A.N.A Support page with links to useful videos & "how to" informations :
New Installation :
After upgrading, be sure to use a clean archive from A.N.A 1.5 ( new download from Sonic Academy ) to avoid any corrupted archive issue. Use Keka to unzip it and be sure to use the x64 version of the A.N.A installer as mentioned below :
- Latest version for A.N.A is 1.5 , upon download you have this archive file Sonic_Academy_ANA_V1.5_ALL.zip
Keep it on your desktop & be sure to use a trusty app to expand the archive, the free KEKA app is a reliable one.
Once you have uncompress this .zip archive, be sure to use the MacOS x64 bit installer version for A.N.A
Finally, there's often files permission issue happening on macOS, so you could use the disk utility to fix permission or also a free app like Permission Reset http://www.ohanaware.com/permissionsreset/ to fix permission on specific files such as the A.N.A 64bit pkg installer, the .au plugin itself, the full Sonic Academy folder in yourmacHDD/Library/Application Support/Sonic Academy
Going through all the above steps will make sure we've trouble shoot the basics of a clean installation procedure, hope that will help to fix tis issue.
