Question: upgrading operating system and hdd on Macbook pro mid 2010
I have a 15" macbook pro mid 2010 2.66 GHz Intel Core i7 8 GB 1067 MHz DDR3 running on OS X Yosemite 10.10.5.
In the past I removed the cd and replaced it with my old 500 gig hdd and used the hdd slot for a ssd 500 gig which my system runs on. (so now i have two hard drives: sad and hdd)
I would like to upgrade my hdd capacity, what is the maximum size i can use? and what model is compatible?
I would like to upgrade my operating system, what is the latest I can use?
Many thanks :-)
MacBook Pro, iOS 8.1.2
