A couple of days a ago, I noticed there was lots of chatter coming from the hard drive.* I also noticed that the Mac Pro was very slow at doing most things, lots of beach balls and applications not responding.* Right now, all I can hear is the HDD * I opened up activity monitor and noticed that a process name called - mdworker - was using 8.83GB or Real Mem and around 11.80GB of Virtual Mem.* These figures fluctuate, the Virtual Mem has gone as high as 14GB.* Sometimes the process goes down very low to say below a GB, then rises again. * I have 10GB of ram installed inside the mac.* Furthermore, I've seen 100%of CPU use though mdworker. * I've been reading about this problem, lots of advice says to move the HDD image to the privacy pane on spotlight as this is a indexing/spotlight issue, though I still want to use spotlight. Didn't mean for it to have stars in, copied this starlight from a another forum where I've posted. * Will this process ever end, or is there a way to stop it, as is using up all the resources? * The only thing I've installed of late is a music plug-in called Geist and an expansion pack which came with it. * Right now I can't rally use my mac like before, I'm writing this on an iPad. * Any help would be great, as the mac is integeral part of m work.
