    Hi all,

    I have a few issues with a custom build version (maxed out processor, SSD drive and RAM) of the above desktop running El Capitain 10.11.3. Two of these are the following:

    1. I put the computer to sleep by clicking on the Apple icon in the top-left corner and clicking "Sleep". I leave it overnight and when I come back to the iMac a message comes up stating that the computer and to be restarted due to a sleep wake problem. I have never seen this before on other Macs I've had. I have no software installed it yet and the only devices connected are three Thunderbolt WD My Studio drives (6TB per enclosure) that are daisy chained using Thunderbolt.

    2. When I launch Safari I get a lot of beachballs. Eg. YouTube, Google searches and the Macrumors forums!

    Anyone has a clue what could be going on here?

    Many thanks!

    reinstall OSX, I know it's new but these little bugs can often be sorted with an operating system reinstall.
