Hi it's me again.

Hi all,
A fellow user has posted the following workaround, which MOTU recommended for UAD plug-ins on the MOTUnation forum. It also worked for the VE Pro 6 plug-ins here on our systems!
Workaround fix for VE Pro 6 plug-ins in DP 9.51 on macOS High Sierra:
1.) Run the latest Vienna Ensemble Pro 6 (OS X) installer from https://www.vsl.co.at/en/MyVSL/software_installers. Restart the computer.
2.) Open the Applications folder and drag the Digital Performer application to the trash. If you have multiple versions of DP, be sure to drag all versions to the trash.
3.) Hold the Option Key while clicking on the Finder's "GO" drop-down menu, select Library, then open the Preferences folder. Find the com.motu.MotuAudioSystem folder and drag it to the trash. Empty the trash.
4.) Download the DP 9.51 installer available at motu.com/downloads and run the installer.
5.) Find the VST folder (System HD/Library/Audio/Plug-Ins/) and rename the folder to anything other than “VST” (for example, “VST_temp”).
Your Audio Unit and MAS VE Pro 6 plug-ins will now be available in Digital Performer 9.51. Please be aware though, that your VST plug-ins will of course NOT be available after renaming the VST folder!
I hope that helps until MOTU and our developers can find a real solution!
Best, Marnix
Can confirm after doing myself that this ONLY WORKS ONCE! In order to get it to work 'every time', you must delete the audio unit and VST (more in the edit) CACHE files inside the com.motu.MotuAudioSystem folder EVERY TIME after you have closed out of DP. If you've customized which plugins you're loading, especially VST's (see below) then do NOT erase the Audio Plugin Prefs file. The downside to this is that it rescan's the plugin's every time you start the program after deleting the cache's -- not a terrible solution if you work in one solid chunk on one single project the entire day and you dont have a million plugins.
Also, to a few someones out there, telling people not to upgrade is basically telling them to 1) accept security flaws that could put their identity/finances/computers at risk and 2) accept that developers don't have to care about getting upgrades correct. Shame on you.
EDIT: I can confirm after some testing that you can have DP load VST's through this method, though it takes FOREVER. Therefore you do NOT need to change the VST folder name, of you can change it back to normal if you go through the above steps, then select which VST's you wish to load through preferences. This will add a Audio Plugin Prefs file, which you'll need to keep so that all the plugins you desire will load after deleting the cache's. I suggest, however, not loading the VEP VST, because that's probably the issue, but since this is a Mac only problem just use the AU. The other methods described on other forums don't work unless I'm doing it wrong. It's a bad solution, but a solution nonetheless.
