Q: Booting from external SDD (running Mavericks) on new MBP Retina with Yosemite.
Hello,
I just bought a new Macbook Pro 15" Retina (2.2 ghz) because my previous laptop stopped working. I was previously running Mavericks, and I'm trying to use my old SDD drive as a startup disc (through USB 3 enclosure) but its not working. I get a grey screen with a circle and line through it. I just came to know that I will not be able to startup up Mavericks on a laptop that came with Yosemite. Is this true?
If I chose to recover the data from the disc or Time Capsule (using command + r) on starting up, will my data get copied to the new drive with no issues? Or is it best to run the old drive and update it to Yosemite to be able to use it as a start up disc?
Thanks,
MacBook Pro with Retina display, OS X Yosemite (10.10.5), Boot from Mavericks drive
