Why sometimes does my mac lag even after fresh install OS-X
Hello everybody,
I need help about my mac. The problem is my Mac seems to be lagging, I often encounter the spinning Colored beachball often shows up even when I'm just opening the Finder only. But when I don't do anything its fine, the problem shows up mostly when I'm copying data it will stop for sec then the process will continue again, I already installed a fresh copy of the OS-X and nothing changed, I also checked the disk with Disk Utility and any other software it seems fine,
Sorry for my bad explanation,
Thanks.
Is this a good question?
