Yup, that's the first sign of the hard-drive dying.
huh?
It's been stuttering for years. We tried to fix it with an upgrade to Lion but that didn't seem to solve it. At least not in Firefox or Safari (though he hasn't tried Chrome yet). In fact, flash video stuttering has been common on Macs for a long time, but I haven't noticed much of a problem on my 2011 MBP. Google it. There's a reason why long-time MBP owners have a strong dislike or Flash, and it's not because the shit has a history of good performance.
Anyway, it's not a HDD issue. Not sure why you mentioned that you thought it was.
I guess I'm just wondering if the new OS has anything under the hood (performance improvements) that may alleviate the issues, and if a clean install is necessary on Macs like it is on Winboxes.
Well it's worth a try, Macs tend to get cluttered over time (especially if you dont uninstall Apps properly) and the performance will deteriorate.
alright. If a straight upgrade yields the same issues, I'll just clean install it for him. Hopefully the former will be okay. Formatting and reloading always fucking sucks.
