Forum members: To aid Martin and those who wish to help, I’d kindly suggest adding your current “setup” to your signature. This makes it easier to eliminate issues indigenous to PC or Mac.
For instance: 2018 iMac OSX 10.13.6
I7 Quad Core 4.2 gig 32 bit ram(Apollo X8 interface)
Moderator…please feel to move this post if necessary. Just want to help!
