I switch back to Mac from Linux so I could have grep, pipes, sed and all the UNIX stuff alongside real commercial applications like Word, Excel and Photoshop.

I switch back to Mac from Linux so I could have grep, pipes, sed and all the UNIX stuff alongside real commercial applications like Word, Excel and Photoshop. The irony is now I run Linux in a VM because the toolchains for the embedded work I do all run there. In principle I can make it all work in MacOS, but it already works in Linux.
