My iMac is a 2009 model. I just had a new bigger hard drive installed. Now when it is woke up, it shows the desktop, then a black screen, wakes up and then a black screen, continually. The only way I get it to stop, is shut it down, the reboot it. Then it is ok until the next time it goes to sleep, then it starts all over. Any suggestions on how to fix this?
