MacBook 10.6.8 OS X; Intel; have Bootcamp split drive for Windows on one side and Appleworld on the other; rarely use the Windows side, and now my Appleside is bringing up a dialog every now and then telling me that my start-up disk is full .... unfortunately, that information alone is rather useless to me as nothing is indicated about how to alleviate that; OS X info tells me: capacity 49.39 GB; available 336.2 MB; Bootcamp info tells me: capacity 30.29 GB; available 20.6 GB. So -- can I resolve the "start-up drive" business by moving about 15 GB from the Bootcamp side back over to OS X? Have no need for all that capacity over there and apparently could benefit from having it on the OS X side. If the answer is, yes, you can do that ... then, how? Thanks!
