theres a couple stuff i have in my game, maybe this can help fix the issue, i tried doing that but nothing was working, a lot of my hairs, clothing like tops, jeans, dresses. aren't popping up, and its weird that its just those things, the eyes custom content works fine. its just tops, jeans, dresses, hair custom content that i know of right now isn't popping up. i recently downloaded a mod the sims sims 3 folder https://modthesims.info/wiki.php?title=Game_Help:Installing_Sims_3_Package_Files/Setup_and_Files
that way so my game would help locate the mods that i am installing. another thing if it helps i am running it on imac m4 sequoia version 15.6.1 with the game version of 1.70.305.024017
i also have this installed as well https://modthesims.info/d/654691/eyelash-mesh-terminator.html the hairs that wont pop up are from shlmydim and lealillith both on the sims resource.com which i downloaded both of them before on my gaming laptop before it was broken with no problems. every thing i downloaded was popping up before.
