I’m back and have managed to make a short video how 32Lives freezes my MacMini (late 2012), 16 GB Core i5 2,5 GHz with a SSD start volume (1 TB, APFS, attached via USB3):
Hope that the quality is good enough to see what’s happening. I have added a Memory Clean 3 window to show the degression of free RAM. You can also see in iStatistica on the right that 32Lives eats up the whole memory; there’s no other app active. At the end of the movie my mac was frozen and I had to reboot. This is reproducible every time I start 32Lives.
