Older versions available?

Hi! Is there any way to get this on high sierra? The mac app store will not let me download this.

I'm afraid no. Core Shell and Core Tunnel support macOS 10.14+ by now, you can re-download last compatible versions only if Core Shell/ Tunnel has been installed before.

You can browse your download history by going to App Store and tap the circle face on the bottom left corner of the window.

Kindly Regards,

Ok, thanks! I just found your software and was really eager to go for it.
Thanks for the tips, but I have not downloaded it before.

Cheers,
