Hi All, First post - long time mac user. I have a new rMBP arriving tomorrow. I am currently using a mid 2010 C2D MBP that I have the Yosemite public beta on. I have time machine back ups and was planning on using these when my new laptop is here for migration. I have read that this may cause issues if trying to use my yosemite back up onto my new mavericks MBP ? Would I be better off downloading the Public Beta onto my new machine before trying to migrate my back up data over? Thanks in advance!
