I was sort of shocked when after posting on one of these forums that I shut down my mac pro after each use that someone replied that doing so was harmful to my computer. Is this true? Am I better off putting my Mac in "sleep" mode instead of shutting it down? I know that on PCs, it was never a good idea to constantly put your computer in hibernation or standby. Even I noticed that after doing so for a few days, Windows just started acting flaky. ...but this is OS X and Mac Pro. Perhaps I need to rethink how I operate my hardware. Would love to hear advice on the proper way of turning off my computer. Thanks!
