Q: 2009 MacBook reinstallation.
Hello Everyone.
I have a white MacBook from 2009 which shipped with SL but is currently running Yosemite, and I've been thinking about erasing and reinstalling as it's been a little sluggish lately, which I assume is due to it's age and the fact it's never been wiped and stuff before.
If I booted it into Recovery Mode and erased/reinstalled OS X would it reinstall SL or Yosemite? I've tried googling it but I get mixed answers.
If it does reinstall Snow Leopard, I have a 2014 iMac so could I just take the Yosemite installer app and put it on a USB and "drag and drop" it onto SL to reinstall? or would I need to format the USB a specific way for the installer to work as I don't think apps worked on that OS. Sorry if this doesn't make sense.
Thank you
MacBook, OS X Mavericks (10.9.4)
