Lately my Macbookpro has been..acting up..lagging. The dreaded biacthball shows up more often and my USB thumbdrives take a long time to mount..while waiting for it..nutt;n works. They do work fine( quick to mount) on my Imac.
It is older( 2009) battery says replace soon but it acts up regardless if I have it plugin in or not
Plenty of harddrive space and I am not overtaxing it with applications etc
I run clamXav and I stay away from the really bad Pron sites:)..any ideas
