Hey guys, I've got a: MacBook Pro "Late 2011" (was purchased apr. 2012) (MacBookPro8,2) and I just installed, the following components: ***2x Samsung 850 Pro 512gb SSD (both internal)*** http://www.amazon.com/dp/B00LF10KTO/ref=twister_B00M0QYEWC ***16gb replacement RAM - patriot 16gb ddr3 1333hz 10600 SO-DIMM*** http://www.amazon.com/gp/product/B006BMBUAA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 I used the OWC Data Doubler to remove my SuperDrive/Optical Drive, and mount in my 2nd Samsung 850 Pro 512gb SSD.. I flashed a 64gb USB drive with the OSX Recovery thing, so I just went ahead and installed both SSD's at the same time.. The weird thing was that the OSX Recovery Assistant window came up, with the standard options on it "Reinstall OSX, Disk Utility, etc, etc.." I partitioned both drives with 1 partition, made sure GUID, tried to do the Install OSX from the menu, kept getting error message when selecting a drive, went back and made only 1 of the GUID, and just reformatted the other one "Mac Journaled Extended", tried again, still no luck.. Luckily for me, I had an Apple Time Capsule with several recent backups of my HDD on it, so I gave the "Time Machine Backup" a try, and luckily for me, everything booted up perfectly.. I was planning on doing a fresh re-install (not a restored Time Machine backup), so I went ahead and ran the system wipe from the beginning, since now it has a stable OSX to do so from.. So far, I've ran hardware tests, both the short and extended ones that OSX offers.. everything came back working properly, including both of the SSD's and additional memory I had added.. I have also purchased the "TRIM Enabler 3.0 Pro" from: http://www.cindori.org/software/trimenabler/ I have it turned ON, and it's showing everything in working, positive, successful order.. so that's good.. This is my first MacBook Pro, as well as my 1st laptop upgrade experience.. I would say that it's a fairly simple task but may not be suitable for the novice.. Is there anything else I should be doing to further optimize this upgrade installation? Here are the things I've done: -Ran both OSX hardware tests, regular and extended, both 100% success -Ran Fix Disk Permissions -Installed all updates in App Store -Installed "TRIM Enabler Pro" (100% successful reports) This is my first time with a MacBook Pro and I just want to make sure I've covered all my bases and that there's nothing that I've left out.. Thanks everyone!
