Hi,
Thank you! Just wanted to let you know that this was incredibly helpful, and got me up and running with NAM36 on my 2012 Macbook Air running Mojave, and my 2010 MacMini running High Sierra (yes, yes I know! I'm saving up for upgrades!). I'm using the Steam version (on offer for less than a fiver! bargain!)
I'm super newbie coming back to the franchise after last playing SC2000 as a kid, and not that tech-y, so a step by step guide like this was invaluable. Thanks! Some observations of my own in case any other similarly bewildered SC4/NAM wannabies happen to come this way:
Having successfully installed the NAM according to InfiniteCities' and Mon4lisa4's instructions I had the crash-to-desktop problem experienced by a few people whenever I open a city from the region map.
I tried the messing about with JDatPacker to no avail (not really sure what I'm doing - it's too complex for me!)
But I found that just removing the "SimCity 4/Plugins/MassTransit Lots/High Speed Rail Stations" subfolder eliminated the problem.
I'm sure I've lost some gameplay options by doing this, but for someone who's brand new to the game and just wants a few more curvy road, traffic and mass transit options to play with it's good enough for me. I might revisit again to try a proper fix some time if the lack of high speed rail options proves to be a deal breaker.
Anyway, thanks again for the install guide. My SC4 journey begins!
