I've upgraded to Yosemite on MacBook Pro (13 inch, mid 2012 model). Since doing so, I cannot boot into rEFIt; no OS options are available; it just boots into Mac OSX yosemite directly. 2 471351 Mac OS X HFS+ 3 331140887 Mac OS X Boot 4 332410423 Mac OS X HFS+ 5 333764287 Unknown 6 580350591. The steps to install rEFIt this way are as follows: Download and mount the rEFIt-0.14.dmg disk image. Double-click on the “rEFIt.mpkg” package. Follow the instructions and select your Mac OS X installation volume as the destination volume for the install. If everything went well, you’ll see the rEFIt. The Mac's built-in boot manager is awkward to access and limited in its capabilities. I presume this is what motivated Christoph Pfisterer to create rEFIt. I forked rEFIt into rEFInd after rEFIt fell into disrepair. I was more motivated by boot issues on UEFI-based PCs, but rEFInd remains a way around the limitations of Apple's boot manager. Copy the “efi” folder from the rEFIt distribution to the root level of your Mac OS X volume. Open Terminal and enter the following commands: cd /efi/refit./enable.sh When prompted, enter the password for your user account. If everything went well, you’ll see the rEFIt boot menu on the next restart.
