Hi I have a 2010 iMac and I installed the latest update of Mavericks and it takes for ever to do anything. I have to wait 2 minutes to see whats inside a folder. I restarted with rebuilding the PRam. I ran disc repair from an iMac via firewire target disc mode. From target disc mode I can open all the files just fine, so is not a problem with the hard drive. I ran disc repair and it resolved some issues but not a big deal. It seems is a problem indexing everything. But I saw the Spotlight and is not indexing anything. I left it running overnight because yesterday started like that after I installed Compressor 3.5 from the Final Cut Studio. I have several computers running FC7 and no problem at all. I even started to force quite several times from the console but nothing... the computer is slow. The hard drive is running all the time like looking for things. Any help? Thank you guys. --- Doing a search it seems is Spotlight, I am going to shut it down from Terminal.
