What happened?

Txt2img is taking too long in Macbook Air M1. After running a fresh install of the git repository, added a model, a VAE, an some LoRas, the generation process takes almost 1 hour per image of 768x1152, with/without upscaling/refining. Is this normal?

Steps to reproduce the problem

On a fresh install of Forge WebUI in Macbook Air M1, using this configuration:

Time taken: 47 min. 26.2 sec.

What should have happened?

As far as I understand, long generation process shouldn't take longer than 5-10min. One hour seems excessive to me, but maybe I am missing something important here.

What browsers do you use to access the UI ?

Mozilla Firefox
