Hi all, My MBP had been running very slow for a while - beachballs, apps taking forever to open etc. So i backed up, deleted the HD and formatted, reinstalled Yosemite (it was running slow on Mavericks also). I only put a few apps back on but its is still as slow as ever. Its a bog standard machine, no upgrades. Any help much appreciated
