We happened across a macbook6,1 that only had 2 GB of RAM and an old spinning hard drive. Knowing the machine just needed a faster internal drive and more memory to be completely usable, we quickly focused on potential upgrades.

For cost purposes, a 240 GB Kingston SSDNow (SUV400S37/240G) replaced the old hard drive and  the RAM was upgraded to 8 GB, but it took some research on the RAM to figure out what would work best.

Others have reported that 8 GB Crucial RAM kits will work in the macbook6,1, including:

• CT2KIT51264BC1067
• CT2C4G3S1067M
• CT2K4G3S1067M

We purchased this listing on Amazon and at the time we purchased it the last two part numbers, above, were part of the listing; however, the present Amazon listing only seems to include part number “CT2K4G3S1067M” and when our package arrived, the label on the RAM was “CT2K4G3S1067M”. We installed the 8 GB kit on October 2016 and it has been working fine ever since, leaving our macbook6,1 much faster and without kernel panics.

The only slow down my son whines about is the machine not sleeping and waking as fast as it use to, but I told him if this is true, it makes sense. The machine now has to write 8 GB of RAM to the SSD whenever it goes to sleep and it reads this same amount from the SSD when it wakes up. I don’t notice any slow down after the upgrade, but if you believe my 11 year old has noticed this, then the reason above may be in play…
