I have a mac that is running a dual boot with OSX and Ubuntu. I just updated my OSX to the new OSX Mavericks, but when i restarted my computer and tried to enter Ubuntu from r EFIT I just got an error message saying After a lot of searching for solutions, I also found myself in similar situation. The Mac is on pure EFI (non-hybrid), pure 64 bit Linux.
Download the latest r EFind (currently 0.7.4) and issue this command from OS X: I ended up with a long menu of all my Linux kernels and was able to boot directly into Ubuntu / Debian without GRUB menu.
Now at least I can get into Linux and rework the GRUB and look at EFI configurations. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
I had a similar problem but when I tried to launch Ubuntu it came up with something along the lines of "please insert boot disk". After I updated it I had to boot into Mavericks and restart it again but then launching Ubuntu Linux worked fine. Would you like to answer one of these unanswered questions instead?
I fixed the problem by restarting my computer and when the r EFIT screen comes up launch the "Start Partition Tool".
GRAPHISOFT is maintaining compatibility for Archi CAD 17 and 18 and connected products (BIMcloud, BIMx, BIM Server, BIM Server Manager) on OS X 10.10 Yosemite.
Based on GRAPHISOFT’s first tests Archi CAD 17 and 18 generally work well on 10.10 with some issues that are detailed in this article.
BIMx desktop users should note, that BIMx cannot be run until the first compatibility update for Archi CAD.
The compatibility update for Archi CAD 18 has been released.
Archi CAD 13-16 version can run on Yosemite, though these were designed to work well with older versions of the operating system.
As a result there is no technical support for operating system specific problems, like the ones explained in this article.
Archi CAD 12 and older versions cannot run on OS X 10.10 due to technical limitations.
