Intermittent freezing/typing lag with El Capitan
Experiencing intermittent freezing (typing lag) since upgrading to El Capitan on my Early 2008 15" Macbook Pro. Regardless of application - while typing, the cursor will freeze and withhold characters and then pickup the typing again. Difficult to log into sights requiring passwords because it will freeze while typing a password. It actually has frozen several times while typing into this forum causing me to retype words as I go. I saw something about resetting the SMC on another forum and so I tried that - fixed the keyboard light issue I had been experiencing - but freezing/lagging continues. Any suggestions?
Macbook Pro 15", Mac OS X (10.5.7), 2.6 ghz - Purchased May 2008
