I thought I would try this with no expectations that it would actually work. I
have an apple MacBook Pro from around 2011 installed with the Raspberry Pi
version of Linux.
I tried Andy's " sudo apt-get install linuxcnc" but as you can see below it
fails. I am up to date with update and upgrade.
Is what I'm trying to do even possible? I do have LinuxCNC running on a Pi4.

Your problem is probably the mac's kernel, running the raspian buster,
the kernel has no realtime support.
The git pull of the src is exactly the same. I can use the buildbots rpi
version here on my rpi4b, or I can build
it from a git clone of linucnc's src tree right on that pi.. No
detectable difference.
How does that old mac boot? If it is a "u-boot"er, then there is an odd
chance my kernel can run it. Also, I /think/ the
arm kernel of: pi@rpi4:~ $ uname -a
Linux rpi4.coyote.den 4.19.71-rt24-v7l+ #1 SMP PREEMPT RT Thu Feb 6
07:09:18 EST 2020 armv7l GNU/Linux
Might run on your mac. I /think/ its also available from linuxcnc.org.
If it is mine, install is just unpacking the tarball, seeing two directories
in it, and copying each to the same directory on your mac, u-boot will
need /boot/config.txt edited to select the alternate /boot
to get the above output after a reboot.
Make recovery backups first of course.
My nearly 80 yo 11x54 Sheldon is being run by an rpi4b, works fine. Has
been for several years, starting originally with
an rpi3b, slower by quite a bit.
Take care & stay well, John.

oh oh, bullseye, Last time I checked, bullseye's python was too new,
busters works fine.
