free just dwn loaded it. seems to work well, last a time an fixes issues. slooow on the old hardware.

for the thrifty gay boy, having aged apple hardware, this version fixes issues. That is if you MUST use Yosemite.

Owning old hardware; both a mid 2007 and a 2010 macbookpro that i put the original Yosemite on. seems 10.10.3 has fixed many bad issues.

good luck
