Change that value from 1000 to 501, and when you reboot your user will be listed in the login screen. To do this, just open a Terminal and run gksudo gedit /etc/fs and search for UID_MIN in the text file. You may also want to fix your login screen, since by default Ubuntu won't list users with a UID of less than 1000. Now, you should be able to read and write to both your Mac and Linux user's home folder, no matter what OS you're logged into. This will change your Linux user's UID to 501 and fix your home folder permissions so that you still own them. Sudo chown -R 501:yourusername /home/yourusername When using Disk Utility 16.3 with macOS Sierra to format a 'thumbdrive' USB 3 Lexar flash drive (64 gigs), when I choose a Format of ‘Mac OS Extended (Journaled)’, I get a list of three Scheme items: GUID Partition Map. Then, open up the Terminal and type in the following commands, once again hitting enter after each one (and replacing yourusername with your Linux user's username): sudo usermod -uid 501 yourusername Type in a new password for the temporary user when prompted. Apple has long offered two versions of the same HFS+ partition formatting scheme used to create a filesystem for a Mac-mountable volume: Mac OS Extended (Journaled) and Mac OS Extended. Journaled is a bit slower than non-journaled, though. It both prevents a disk from getting into an inconsistent state and expedites disk repair. So, run the following commands in the Terminal, hitting Enter after each one: sudo useradd -d /home/tempuser -m -s /bin/bash -G admin tempuser Journaling is a technique that helps protect the integrity of the Mac OS Extended file systems on Mac OS X volumes. First, we're going to add a temporary user, since we don't want to edit a user that we're currently logged into. In this section, we will see how to add a partition to a disk formatted with Mac OS Extended (Journaled). 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. That doesnt seem different (in fact since the journal is probably far form the data to be written you have some extra cost from seeks). 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.
