I'm running Catalina 10.15.4. Downloaded the .DMG, mounted it, dropped the app in the app folder, ran it, gave it my password but after trying to install the driver for a few seconds, the window goes away although the icon in the dock bar is still lit, so when CMD+TAB back to it, it shows this:

So first, I shut down all running apps and tried again without success, then I rebooted and tried it first thing after login without success... then I ran the terminal uninstall command you have posted on the web site ... that didn't work either.
Is there a more direct way to get the driver installed? Like a sudo method perhaps?
Thank you
Try brew cask install eqmac
I have the same issue.
I tried uninstalling eqmac (remove from applications, run cleanup command in terminal), then installing the latest (v0.3.0) version manually from GitHub. Homebrew cask still only knows about v0.2.0, so I didn't try that. MacOS 10.14.6 (18G5033) here.
Can you please read through #317 and try some of the steps the user went through there. Make sure to use v0.3.1 when you try.
Restarting my mac.... oof, that's a big step to ask from a pro user like me! ;)
JK. I'll try that later, and the other steps described! Thanks for the response.
Haha! I know it's not ideal. The installation process is trying it's best to not have to restart, but unfortunately this process is not very predictable :(
Just rebooted, still cannot install driver. I'm not sure what steps I can take from #317, because it seems that that user does have eqMac running successfully, but had troubles _upgrading_ the driver. I cannot even open eqMac from a clean installation without the driver install failure.
Try running these commands in Terminal:
sudo cp -f -r /Applications/eqMac.app/Contents/Resources/eqMac.driver /Library/Audio/Plug-Ins/HAL/
sudo launchctl kickstart -kp system/com.apple.audio.coreaudiod or just restart your Mac
@nodeful Thanks man! sudo worked for me! Catalina 10.15.5.
@nodeful
macOS version 10.15.7
download the latest available eqMac.pkg from https://eqmac.app/
I've got the same dialog as @EasyG0ing1
Unfortunately, the abovementioned commands did not help me:
sudo cp -f -r /Applications/eqMac.app/Contents/Resources/eqMac.driver /Library/Audio/Plug-Ins/HAL/
cp: /Applications/eqMac.app/Contents/Resources/eqMac.driver: No such file or directory
Rebooting also did not help.
Is there anything I am missing or I can provide to you for father investigation and resolution?
