My Macbook Pro is (A1278) Mid 2009 2.26 GHz. Can my Macbook pro use 1tb hdd? and what is the largest amount hhd can fit?
OS X El Capitan (10.11.6)
The largest single Hard Drive your Mac can use is about 8 million million Terabytes.
The limiting factor is what is available in the marketplace, not Hardware or software limits in the Mac.
