Just to let you know, I have inteen running in my mac with no problems. I have the version for my specifics EPs. Check if you downloaded the correct version according to the EP's you have.

Then, create in your downloads folder a new folder called #hacks (so it runs first); inside this create a new folder for every hack you have EXCEPT INTEEN. Every folder for other hacks should be named in an alphabetical name that goes after inteen. I named insiminator folder only simenator so it goes after the inteen files. So my hacks folder is organized in this way:

_enableColoroptions.GMND
censor.package
Inteenmater_A (through _F)
A folder named simenator

As Beoxboxboy suggests below, it might be necessary to delete the grops.cache file to force the game to re-read the files in the new order.

Hope it's useful.

Good choice of sites the artists here and there are superb!!!

Follow the tips in the sticky How to download a RAR file with Safari. ( I use Firefox myself)

Briefly - after you decide on the item you would like to use ... one click on the link (not a Q-Xpess link LOL) this should open a small window which will ask you how you want to open he file and where you want to save it. (I save it to my disk on my desktop) If you have one of the programs from the 'sticky' above you then need to double click the rar file to release the goodness inside.

If you find it is .package it goes in the Downloads folder if it is a .Sims2pack double click it and follow the instructions.

Hope that helps a little. Read the stickies above as there are quite a few traps to fall into. I have found the instructions there so helpful.

Enjoy your simmies!!

Slightly off topic. One of my reasons for using a mac is to keep clear of viruses. Therefore I don't like the idea of programs that work  'in the background'. Viruses by definition work in the background. So would a mac Q-Xpress which works invisibly be safe? or am I just being paranoid?
As it is now I can watch what is being downloaded in the downloads window. By the same token I can choose to do other stuff and not watch the download. I like to have that choice.

You don't, it's a pc only program, like every other sims-related program other than bodyshop...
