Hello,
Sorry about the issue! We have gotten some reports of this issue, particularly from users who have the game installed on a traditional hard drive, rather than an SSD. In some cases it’s necessary to just wait for a longer period of time for the game to start.
However, looking at the specifications of your Mac Mini, it seems it doesn’t meet the system requirements for Last Epoch, in particular the GPU portion. Your Mac Mini only has graphics hardware that is integrated into the CPU, which is much weaker than a discrete graphics card from AMD or Nvidia. As such, we can’t guarantee the game will function optimally.
If you’d like a refund in light of this information, you can do so through Steam if you purchased the game there, or by emailing [email protected].
