First, we're going to add a temporary user, since we don't want to edit a user that we're currently logged into. If your User ID is something different from 501, replace 501 with your other UID in the terminal commands below.īoot into Linux (we're using Ubuntu in this example) and fire up the Terminal. By default, the first user in OS X has a UID of 501, but you can double check this by going into System Preferences in OS X, right-clicking on your user, and hitting Advanced Options. Unless you have a reason for choosing otherwise, we're going to change our Linux UID to match our OS X one, since it's a bit easier.

we just need to change our UID in one OS so that it matches the UID in the other. You should have read and write access to your HFS partition-however, the permissions on your Mac user's home folder will prevent you from reading or writing those files. A new option to Disable Journaling will come up in the menu. Click on your HFS partition, hold the Option key, and click File in the menu bar.

To disable journaling, just boot into OS X and fire up Disk Utility. Journaling is a feature that improves data reliability, and unfortunately it makes HFS drives read-only in Linux. By default, Mac OS X formats volumes in journaled HFS+ volumes.
