Hi, I installed a Crucial BX200 SSD and did a clean install of 10.11.4 on my late 2008 uMB with 4GB of RAM. Everything seems to be working fine except two issues that I hope some of yall have suggestions on. 1. When I physically push down on the trackpad to select something (for instance to open a folder or select a web link), it doesn't work. Tapping the trackpad will work for this though. I also cannot use the trackpad grab an icon and drag it or to select text. A usb mouse is currently being used for this function. I have gone through the settings and can't see any options that I would of have missed that would turn this on. 2. I don't think my Macbook is going to sleep. When I close the lid, the little status light that is on the right front of the case remains lit solid and doesn't pulse like it used to, to indicate the laptop sleeping. If I choose sleep from the apple menu at the top left, the screen turns off but if you put the laptop to your ear the fan remains running. I can't imagine that I am not waiting long enough as I have watched the laptop for a few minutes and didn't notice any indication that it had actually slept. I have googled the sleep issues a bit but don't seem to have all of the options in my Settings -> Energy Saver menu that if I were running 10.11 on a newer laptop. On both the Battery and Power Adapter tabs, I have 'Put hard disks to sleep when possible' and 'Wake for network access' selected. Though on the timers, I have Computer to sleep set at Never for both Battery and Power Adapter as I only want the laptop to sleep when I close the lid or tell it to, not on its own.
