After several reboots I managed to close most of my applications but the problem presisted. My free disk space is disk0s2 i/o error about 11GB. I opened “Spotlight” and saw the file indexing process in progress. After waiting for about half an hour I have decided to turn the indexing off, and did that through terminal. The slow performance persisted and when I opened the “Console”; I am getting PM kernel: disk0s2: I/O error Every second. As per Google search this is an HD problem. But how and why? Among this error I am also getting a bunch of repeating messages: Aug 4 22:37:03 MacBook–Air–2 com.apple.launchd[1] (com.apple.iCloudHelper[4459]): Exited with code: 1 Aug 4 22:37:03 MacBook–Air–2 com.apple.launchd[1] (com.apple.iCloudHelper[4459]): XPC Service could not exec(3).
