Are you using linux operating system on a macbook and you also have some partitions which are formatted in HFS+ (journaled) ? Normally the mac partition is automatically mounted in linux system with read-only permission, means you cannot create or delete any files or folder in mac partition.
Actually there is a workaround for this access by disable journaling with these following steps:
- Boot into mac os x
- Launch Disk Utility
- Select the partition you wanted to access from Linux
- Hold option Key still, and browse the file menu and choose 'Disable Journaling'
Done !!. Restart and boot into linux system, from there after you have full access to the mac partition.
Note : By default, Mac OS X formats volumes injournaled HFS+ volumes. Journaling is a feature that improves data reliability, and unfortunately it makes HFS drives read-only in Linux.
