Today I tried to start my virtual linux machines (created in vmware workstation on windows to install/upgrade eBS environments) on my MacBook Pro. I downloaded a trial version of Vmware Fusion. When trying to start a virtual machine, Vmware would show me the following error 'Read only file system' and the machine would not start. It seemed I could not write to the folders containing the Vmware files. So, this is a Mac problem ?
It seems my Mac cannot work with the NTFS filesystem on my external disk. To solve the problem I downloaded the following file 'ntfs-3g-2010.5.22-macosx.dmg' from http://www.macupdate.com/info.php/id/24481/ntfs-3g.
After installing the file, I was able to open my virtual machines on my MacBook Pro.
