@bla32123 Only just uploaded that today I’m still busy even with everything locked down due to my job.... I uploaded an updated PKHeX.app select the newer one. After downloading open terminal and run the following command on the still compressed download   xattr -d -rs com.apple.quarantine “drop wrapper here”   Then press Enter, now unpack the download and love into ~/Applications   Now the application should run without issue on 10.9>10.14 macOS
