My apologies if this has been covered - I've searched extensively and can't find the answer and would like some help, please.  All of the trees and MMPs have disappeared from my latest city. I gather this is a result of "prop pox." So I read each of the following carefully:

https://community.simtropolis.com/forums/topic/70495-game-framework-compatible-dll-loading-and-other-modding-discoveries/ I downloaded the sc4macinjector and ran it. All seems unchanged - no harm done. (I backed up plugins and regions just in case.) I downloaded sc4fix - which seems to be doing wonders for our Windows friends - YAY!!! It is a .dll file. I have no clue what to do with it. My VERY basic computer knowledge is that .dll files can't run on Mac. Regarding the sc4macinjector it says the following on its page: "What does this do
SC4MacInjector allows the Mac equivalent of .dll mods to be loaded on Aspyr's port of SimCity 4 for Intel Macs. Note: you will not be able to use Windows .dll mods directly. They need to be targeted specifically for Macs as .so files." OK. I comprehend those words, but haven't a clue as to what that means in action - or if there is something I can do to target a .dll file as an .so file. <insert very confused llama, perhaps > 1. Do I actually have prop pox? Have I made the correct assumption that the pox caused my MMPs and props on small residentials to disappear?
2. Can someone guide on what, if anything, there is to be done about it? I feel clueless and in way over my head from a technological standpoint. Like... I understand technology better than your 90 year old grandma who just made you those amazing cookies*, but ... sometimes... not much. *A hypothetical grandma. Now I want cookies.
