bootcamp support software which version for early 2009 macbook?
I have an early 2009 Macbook w/ Core 2 Duo 2Ghz, nVidia 9400M display, 4Gb DDR2. Tried to use bootcamp to install windows but I got stuck at bootcamp claiming that there's error saving the bootcamp windows support software. So I intend to go thru the manual software installation route: I searched around and there seems to be two version: 5.1. 5621 or 5.1.5640.
Boot Camp Support Software 5.1.5621
Boot Camp Support Software 5.1.5640
Both webpages do not list my model and I'm suspecting that might be the problem causing the above error. In any case, can someone tell me whether I should go with 5621 or 5640?
MacBook, OS X Yosemite (10.10.4), Early 2009 Macbook White
