84291 Is there anything I might be able to do to recover my /home?
I am going to make several assumptions:
(1) Your Macbook is old enough to have a 2.5" SATA hard drive;
(2) Despite the lack of a boot partition, the hard drive is otherwise not damaged;
(3) Your Macbook is user-servicable, in the sense that you can open the case and remove the hard drive;
(4) Because the Macbook has been freezing and shutting off, it is probably wearing out, and you plan to use the Thinkpad as your Solus laptop going forward;
(5) The Thinkpad is currently running Solus;
(6) Your Thinkpad has at least one USB Type A port; and
(7) Your objective is to recover your data now on the Macbook and move the data to the Thinkpad.
If those assumptions are correct, you may be able to open the Macbook case, remove the SATA hard drive, use a specialized cable to connect the SATA hard drive to the Thinkpad via USB, mount the SATA hard drive data partition on the Thinkpad, and copy/move your data to the Thinkpad's data partition.
The specialized cable you will need is a SATA to USB Cable compatible with a 2.5" SATA HHD, available from online retailers for about $10 US. You may even be able to borrow one from a friend who does self-maintenance on computers. If you are planning to recycle the Macbook but would like to keep the Macbook's hard drive as an external backup drive for the Thinkpad, a USB external hard drive enclosure/case for 2.5" SATA hard drives will work as well, and can be purchased online for $15-20 US.
I've done this procedure a number of times for myself and for friends, mostly Windows-to-Windows but in one case Linux-to-Linux.
