"I bought iMac in 2011 and worked perfectly fine until 4 days ago. The first sign was everything became so slow. Every task took about 2 minutes to finish or the mouse cursor spinning forever. Then I started rebooting the system. The problem remained. Then I realized, since I bought iMac, I never used time machine or external drive to set up the backup files. I wonder if anyone could tell me a solution to recover all my files in iMac."
