I HAVE seen other threads on similar topics but haven't seen an answer for my set of circumstances. I have fast internet at my business premises. I have the lowest speeds possible at my home. I have an iMac in both places. Each iMac has my one iTunes account installed. When I try to download app updates at home it can take 3 hours for one to finish. When I am in work it takes any where from a few seconds to 7 minutes. Big difference! I want to download all my updates at work and bring them home. I tried doing this by simply copying the Mobile Applications folder on to my external hard drive then moving them over to the same folder on the home iMac. (I renamed the original and kept it, then added the new ipas to a new folder called Mobile Applications.) HOWEVER. . . Although this ought to have worked when I went back into iTunes it still said I had uploads to download and it looked like the new folder wasn't being taken into the equation. At this point I backed away carefully, deleted the new folder and put back the renamed folder to where it belonged. Is my theory right? Should it have worked? How do I make iTunes see that the updates have already been done? I'd very much like not to have to tie up my internet for hours doing these updates when a few minutes in work is all that is required. HELP?
