Hello again, Juha, you have actually indirectly helped me out. When you spoke about how easy it was to achieve on Linux, I was thinking what a shame that option isn't available to me. Then I realised that of course, it is available to me! I already have Lazarus 1.6.4 installed on a Windows 10 virtual machine under Parallels, and of course, there's nothing to stop me installing Lazarus on one of my Linux VM's.
I guess I had become blinkered thinking about Lazarus on the Mac, and it took a mental prod from you to jolt me out of that. Thanks very much!
Cheers,
Carl
