Easy as following the directions & a YouTube video
Wanted my MacBook Pro to run faster, smoother & quieter.
I remember the optical drive & placed the old HDD in it's place & then installed the SSD as the main drive for the computer.
W/ a fresh install of the OS...my MacBook Pro booted up in no time & I look forward to still using my laptop for a/v editing
Went well. I did skip a step when it came to unplugging some wires because of the age of my laptop.
Take your time. Don't rush. Be in an area where you are free of distractions.
