Machine: iMac G5 iSight, 500Gb HD (240Gb available), 2.5Gb RAM. 3 years and 4 months old.

In the last 4 months or so I have noticed the machine has generally slowed down and this is most notable when watching video in iTunes and separately via Quicktime. Nearly every video (no matter what size or quality) will stick and playback will be jerky.

The only software I have added in the last 4 months was the MacUpdate bundle in January that included VirusBarrier X5 and Drive Genius 2 (the two reasons I bought it). The only app of that bundle I have left installed is Drive Genius.

I have run ‘repair permissions’ in disc utility but that doesn’t seem to have made a difference. Is it worth running defrag in Drive Genius or is there something else someone can suggest to get the ‘snap’ back?

I posted this question on the Apple Discussion Forums and got replies that I carried out but to no avail. They were, emptying caches (I installed OnyX for this) and doing an Archive and Install. The final thing I did was run the Apple Hardware Test from the install disc and it reported a clean bill of health!

Do I just have to accept the machine is over 3 years old so is going to be slower? It does seem strange that it just started happening for no apparent reason.

Same thing has happened with my 1.8DP G5 that is over five years old. Videos are not being as smooth as they once were.

I think the issue stems from the universal code base, personally. Having so much bloat takes time and CPU as well as video card resources that ends up being stutter in video. I can’t watch an HD video on YouTube, but can watch HD native in Quicktime.

I think it is something we just have to accept, as I have done everything in and not in the book to try and get it back to no avail.
