Okay, I'd love to take a laptop with me to shows after last night. It would just be easier for me to put everything in at the time to save time and me having to calculate things (and sometimes getting it wrong.) But I thought I remembered that some people were having difficulty with PP and Macs. My laptop is a Mac, so I don't want to load PP on it if it's not going to help the situation. Does anyone have any info about this? tia
