Since I am still struggling to find a computer for Linuxcnc,
I tried the Live Usb on my Macbook Pro 2012
Latency seems to be ok.

So I installed Linux CNC on an externel hard drive as well as on a USB stick.
Firtst Grub installation failed. After I Connected my computer to the internet via eternet cable from a Wireless extender installation was a breeze no issues at all.

My question is wat is better External USB hard drive or USB flash drive. I am concerned if the USB flash drive will last, especially the swap partition. On the other hans Usb flash drive is much more convenient.

Hard drive is faster, much faster.
USB will last plenty but are inherently slow at everything.

Just wonder in my case
Hard drive is Usb2
Usb Stick is usb3

In this case is the Hard Drive still faster?

Have you a plan to connect hardware to the Macbook, or is this just for simulation?

Ethernet is probably the only option, and I am not sure if they had dropped Ethernet on Macbooks by 2012.

It is the Last Macbook with CD drive built in.
Yes it has a Eternet port.
I don't get wifi to work. Because for driver installation it wants to install a different kernel as well. Latency seems to be ok.

I plan to use it for getting started with my plasma table.
When I find a Good Computer for it I will replace the Macbook.

I keep meaning to try compiling LinuxCNC on a Mac. Linux and OSX are not _that_ far apart.

But, I have so many other ways to waste my time instead.

True it’s a waste of time.
If you port it to OSX you have all these functions that you don’t want. Sleep mode energy saving mode etc. That you don’t want and you have to disable them. I rather stick to Linux. I have a MacBook 4.1 for the kids it is a great Linux machine.

Just some update.
I found Gmocappy Interface is a bit too Lage for a MacBook 13 inch with no Retina display. Part of it gets covered by the bottom panel of Xfce. Apparently The Gmocappy Interface can not be resized because it is already at minimum hight.

I found two workarounds so far.

Move the bottom Xfce panel to the side.

Or use full screen mode.
