I can confirm after a rendering of 410 hours-01 minute 49s on a MacBook Pro (Retina, 13-inch, Early 2015), 2.9 ghz, intel core i5 / 16 gigs, OS 10,14,6 Mojave that the Terragen 4 software latest version is very stable on Mac intel (and my macbook pro also for not crashing for 410 hours non-stop, wow). The Terragen software did not crash once in 410 hours of really complexe 72000 x 5000 px rendering.
My only worry, I want to change my Mac this fall and Apple is removing the Intel chip to replace it with their own M1 chip.
I am told that Terragen will still work with Rosetta 2 in new Mac. Anyone have any info? Thank you !
