Looking for some advice.
I have a 2009 i7 iMac. I recently installed a 500GB Samsung EVO SSD.
Fresh install of ML, then Mavericks upgrades
The system itself is blazing fast now.
However, under ML and continuing with Mavericks, the system will pretty regularly not wake from sleep. I can hear the fans running at low speed (so I know the system is on) - but from looking at the logs and trying to ping/ssh into it I know that the system is not responding.
I originally had an Icy Dock 2.5 to 3.5 adapter. Hoping that was bad I recently replaced that with the OWC Adaptadrive with no change in behavior.
Also updated to the new Samsung EVO firmware.
When I put the system to sleep (apple menu -> sleep) it seems like wake works more reliably. I can also see in the logs that the system wakes up on its own overnight and performs some functions, then goes back to sleep.
When I let sleep happen at night automatically due to settings in Energy Settings it will usually exhibit the symptoms described above by morning.
This definitely falls under the 'system sleeps more than 1 hour and won't wake' type of similar threads I've seen here and in other forums. Less than an hour or so and it pops back to life.
Apple Hardware Test found no errors. I removed and reseated the RAM as well.
I unchecked the box for hard drive sleep.
It is not hibernating. (pmset -g shows hibernate = 0)
I've also tried disabling the password on resume from sleep, and disabling the screen saver.
This is my first iMac SSD - I've installed them in a few Mac laptops and have not seen this behavior before.
So at this point do I try exchanging the drive with Samsung (or Amazon)?
Any other ideas? Anyone tracking any bugs fitting this description with Apple?
