Find a Mac’s serial number in Recovery Partition or the macOS installer

I couldn’t find this anywhere, so I thought I’d blog about this. Thanks to the #general channel on the MacAdmins Slack for the help.

To find a serial number for a Mac when booted into the Recovery Partition or the macOS installer, to go Utilities and choose Terminal, type in ioreg -rd1 -c IOPlatformExpertDevice | awk -F'"' '/IOPlatformSerialNumber/{print $4}'

That’s it, it will output the serial number for the computer.

NetGear ReadyNAS Time Machine Backup

It seems you cannot mount your Time Machine backup on a ReadyNAS device using normal credentials. Time Machine is segmented off with a special user. Which means I needed to restore my computer using Migration Assistant. It took FOREVER over wifi. However, I seem to be missing my Aperture Libraries. What’s the solution? Assuming it was backed up, I need to find the sparsebundle. It took a lot of searching, but I found it, and will share my brilliance with you in case you ever need to find it, too.

/data/.timemachine

To access: SSH in as root. Then copy the files to a SMB or AFP accessible directory.

cd /data/.timemachine
cp -R * /home/<yourusername>
