Re: Putty Alternative For Mac User

Well, let me put it that way: Putty is an app for doing genuine **nix stuff on a Windows OS. So why not try the onboard MacOS terminal?

Re: Access Point & Pihole on the same unit

Well, Pihole basically is a DNS Server, able to act as a DHCP server as well. Everything else needed is an ethernet-WLAN bridge. I am pretty sure, even a Pi2 will do the job. On the downside a Pi typically will not achieve datarates of modern wlan routers with MIMO and beamforming. I am afraid, your...

Re: Raspberry pi 4 cluster

... Certainly USB networking is potentially faster than Ethernet, as long as you use USB3 on the Pi4B. However, you need some hardware in between to allow to USB hosts to talk to each other (AFAIK). Using an Ethernet cable for two Pis needs just that -- one cable. You have to give both of them stat...

Re: How can I shrink Raspbian main partition by maximum before backup?

You are asking for shrinking partitions, then backup. Why not going the other way round, since any repartitioning draws some risk?
Have a look at rpi-clone for cloning and fitting partitions without.
For shrinking even more, give pishrink a try.

And leave your source partition unaltered..
