I am using mac m2. can I follow this course on a VM with linux installed ? the p...

Yeah its not a problem it just might run a bit more slow depending on the processor. If your Mac processor has a compatible instruction set with x86 instruction set then youll be able to do emulation on the hardware its self which is faster, this is automatic in most cases due to virtual box having virtualization enabled. However if you dont have a comaptible instruction set the emulation will be slower as it will be in software only. However this shouldnt impact your ability to follow the course

I think m2 uses ARM architecture so even if I install linux through VM. it wont be enough. right? I need to have a linux machine for this course?

Hey Daniel, waiting for your reply.

Hi,
My original advice applies, you should use a virtual machine with Linux installed on it. You shouldnt have a problem. Also I believe there are ARM Linux distributions so you should be fine, even if you choose AMD or Intel distribution it will be emulated so dont worry.
For faster contact you can reach me directly daniel@dragonzap.com

Apologies for the delay
Thank you
Dan

Here are the steps install virtual box software, download Ubuntu ISO from Ubuntu website, create a new virtual machine on virtual box software, attach the ISO as a disk image on the virtual box software, now install ubuntu on the virtual machine, I found a tutorial online for you for installing virtual box on Mac: https://www.youtube.com/watch?v=hd0Lbtly41Y
