I think I found a solution. I did this and the app opened
Downloaded the App and copied into my Applications folder
Launch the Terminal on your Mac.
Type the following command and hit Enter. Make sure to replace the path with your app’s path.
xattr -d com.apple.quarantine "/Applications/Evernote Legacy.app"
App launched! Not sure if I will get issues or if it will keep working but for now it does.
Now waiting on EN to fix this font size thing.
Thanks and I hope it helps others.
