SOLVED Hello, I have quite puzzling issue with my external drives. I have macbook pro from 2010 with Mavericks and old macbook from 2006 with osx server 10.6.8 I tried to share all folders between both (via get info window) when i choose to do so, I also used apply to enclosed items option. That took a while, and after that I experienced severe problems on both computers and external drives. My rights got totally messy. I had to reinstall mavericks on the newer laptop, and on the server laptop I can only get to the single user or verbose mode. On the old macbook with osx 10.6.8 i can't get to GUI at all. I Also lost rights to my external drives. All rights are set to custom mode and I cant change it. I simply reinstalled mavericks on the newer laptop, but cant access external drives. There is a pop up message about insufficient rights when i try to open it. Is there any way to access those drives and change the rights so that I can actually use them? Is the any way I can access GUI on the old macbook? in single user mode i type ls and i can see all folders and files, just cant access gui. Any idea how i can fix it?
