I've been very happy with my iMac over the four months I've owned it. So far I've resisted installing any version of Flash plug-in. On my previous machines (PCs) I noticed that Flash seemed to be associated with all sorts of freezes, hangs, crashes, and the occasional Malware attack. Maybe I've been hypnotized by the late Steve Job's pronouncements on Flash.. But, sad to tell, it seems like a certain amount of Web content still seems to be available only via Flash. Is it safe, and/or effective, to install Flash on a late-model iMac? Is there anything to watch out for, and are there any steps I can take to minimize the potential downsides. Thanks, in advance, for any feedback.
