Hello, few years ago, I used rEFIt to boot between Mac OS and Windows. When I tried to install it on my rMBP 15" 2014, the site states that it is no longer being maintained since 2013. It points to rEFInd: http://www.rodsbooks.com/refind/ Any of you tried it? Will there be a risk of losing access to Mac or Windows partition if I install it? What is the best Boot Manager for the rMBP 2014 or later rMBP? Thanks.
