Reinstall Mac App Store Apps from the Command Line – from Knightwise

Brew install mas in terminalThis week the irrepressible Knightwise of knightwise.com sent in an awesome tip via audio, and it’s too good not to share in text as well. I’ll do my best to do it justice. I’ll start with the problem to be solved (of course) and then give a little bit of background and then his tip. Finally, I’ll give you bonus tip from me.

The problem to be solved is finding the easiest way to reinstall apps you’ve previously downloaded from the Mac App Store, especially when doing a nuke and pave, or moving to a new Mac but you don’t want to bring along the cruft you’ve collected over the years.

Tiny Tip – Vimmy & Oh Sh-t Git! By Caleb Fong

Caleb FongThe review below is from Caleb Fong, aka @GeekoSupremo on Twitter. Caleb is a long time NosillaCastaway who is also following along with Programming By Stealth. His review is pretty geeky (goes well with his Twitter handle) so I thought it might help to explain a couple of terms he uses.
He’ll use the term *nix which is a term that means any UNIX-like system. *nix can mean any kind of linux, or even macOS since it’s based on FreeBSD which is a descendent of UNIX.

He also talks about Vim. Vim is a text editor in *nix operating systems. It’s a descendent of the original Vi, and in fact, the name stands for Vi IMproved.

Tiny Tip – Show Hidden Files

HiddenThis week’s Tiny Tip is from Bart Busschots. The problem he is solving is how to easily show hidden files in the Finder. There are various tools to do this, including using the defaults write command in the Terminal:

defaults write com.apple.finder AppleShowAllFiles YES

After which you have to relaunch the Finder. It’s not hard to do but you always have to look it up, and after you’re done looking for the hidden file in question you have to flip the switch to NO, and relaunch Finder again.

The Tiny Tip Bart discovered has been available since Sierra, but I sure never heard about it. It’s a beautiful thing.

With the Finder in focus, simply hold down command-shift-. And instantly all windows will show all hidden files! Hit the same keystroke again and they disappear.

I LOVE this tip. The keystroke is even easy to remember because . is often at the front of all hidden files, so command-shift-. Is entirely memorable.

Taming the Drobos

Drobo5nI’ve been working on a super challenging technical project for months now. I’ve wanted to tell you about it but I have run into so many barriers that I was unable to overcome, there wasn’t a good story to tell. I still have not conquered my original task but I’ve had some partial success so I want to do a mini celebration about that.

The Problem to be Solved

Some of this story you may heard before but I want to bring everyone up to speed. A while ago we bought a new Drobo 5N to replace our aging (and never that good in the first place) Drobo FS. The 5N is a dream, with its SSD for caching, it’s super fast and makes a terrific place to store giant and small files alike. I set up a Hazel script to automatically pull over my audio file so my internal MacBook Pro drive doesn’t get filled up any more. Steve stores his giant Final Cut Pro X libraries over on the 5N when he’s done with them. It’s awesome.

Drobos use RAID-like proprietary tools to protect our files from a drive failure, so we do have some fault tolerance but this isn’t technically a backup since our data is only in one place.
