Hi,
I recently bought an M1 Mac. I realise that I cannot run Photoshop CS3 on this machine. However, could I install High Sierra and CS3 on an external SSD and then thunderbolt this SSD into my M1 Mac and boot to the SSD for when I need to use Photoshop.
Many thanks for any help,
James

No.
A Mac can't run a macOS version earlier than which came with the Mac.

Thank you so much for the quick reply. I should have thought of that.
The other thing is, High Sierra cannot run on an M1 Mac.
Thank you. That saves me alot of experimenting.
You're welcome. I should have added you can't even run High Sierra as a VM on an M1 Mac.
Run Photoshop CS3 from SSD External
