No doubt I've inundated this forum with tales of M4 trouble in my '11 13-inch MBP. Before I declare it defective, I want to try one last time to properly install it. It performs well for stretches of time before random 20-30 second beach ball interruptions. The benchmarks are good and all the symptoms I experience, others had once experienced before Firmware 0002. I checked System Profiler and it recognizes the latest firmware. One of the Crucial customer service reps I spoke to, told me to reformat the drive then let it idle for 4-5 hours before installing the OS. How exactly should I go about this? Zero out the partition, then create a new one? Which is what I've done. Once I install OS X, I have to update to the latest version, 10.6.6 -> 10.6.8. Could somebody jot down a list of things to do for mildly retarded individual? I would greatly appreciate that. Thanks!
