USB Version? – Apple Community

September 9, 2025

USB Version? How can I determine my USB version? I have a MacBook Pro 15″ bought in 2010, running OS X 10.9.5. I think it’s 2.0, but I’m not sure. I’ve looked in my system profile and there are several USB listings. I’m wanting to purchase an external hard drive and want to make sure it’s compatible. Do I have to get USB 2.0 or can I use 3.0?
