UE5 Lumen produces no reflections on mac

I have a tried the early access of ue5, on my pc it works like charm, on my mac the same scene that i’ve copied from the pc version is not showing reflections with lumen turned on (i’ve modified the fps starter scene, raytracing is off, lumen is on, works perfectly on pc)
Am I missing something? Is lumen fully supported with macs or does it require an rtx card to show the reflections properly (which is non-existent on macs as far as i know)?
My macbook pro specs:
MacBook Pro (16-inch, 2019)
2.3 GHz 8-Core Intel Core i9
16 GB 2667 MHz DDR4
AMD Radeon Pro 5500M 4 GB
Intel UHD Graphics 630 1536 MB

the Intel UHD Graphics 630 card has shader model 6.4 so in theory it should work
