How do I access my old files from an old Macbook HDD with Lubuntu? I wasn't sure if I should put this on the Apple or Linux stack exchange but here's my problem. So my old Macbook died a while back and I realized that it might have had some important information. My main PC now is a Lubuntu Desktop. So what I did was I bought a SATA with an HDD power connecter to USB cord and I plugged the SATA side into the HDD and the USB into my PC. I was able to get into the HDD's files, but when I was getting into the documents file it said that I could not access it due to permissions. So I changed the permissions and when I clicked apply it said "Error setting permissions: Read-only file system". Can someone tell me how to save the information on the HDD while being able to access it?
This is probably due to your FS type and your old disk which is probably HFS+.
You need to add extra packages to read it.

Here's the copy paste of the answer :

First, make sure that you have hfsprogs installed. Example installation command:
sudo apt-get install hfsprogs

Next, mount or remount the HFS+ drive; commands need to be as follows:
sudo mount -t hfsplus -o force,rw /dev/sdXY /media/mntpoint

or
sudo mount -t hfsplus -o remount,force,rw /mount/point

Finally, if the drive was improperly unmounted or has otherwise become partially corrupted run fsck.hfsplus ... as such:
sudo fsck.hfsplus -f /dev/sdXY
