hi chesterbigbird - i'm trying to help my daughter, who has a similar problem that you helped solved for a poster a few years back, namely, her data and mods viz Sims are filling up the folder that EA automatically created on her Mac Air HD. the video tutorial you sourced was great, but it was for PC. do you know of something equally helpful but geared toward Mac users? The basic task is the same: shift Sims data / mods to external HD, and instruct the program/EA to use the xternal drive for storage, vs the mac's integrated drive. really hoping you can help!
