Slow on mac opening large projects

Opening any project over a certain size on the mac literally takes like 20+minutes…

Has been like this for several versions.

I think the slow down is related to scanning the asset directory… every time it seems to have to “Building Textures” for all the textures in the project…

What are your systems stats? Most Macs aren’t really all that powerful

Its not awful - 5k retina 27 inch
i5 3.5 ghz, 24gb, amd radeon m290x 2gb

Seems to have to do with how many assets are in the project - small and medium projects are fine.

But once a certain threshold is met a big slowdown happens (only on mac, same project on windwos doesnt have slowdown)

UPDATE - After opening like 3 or 4 times, it seems to start much quicker (definitely takes more than one project opening though)

I think it was converting all textures to a mac format and just does some of them each time it starts?
