I finally bit the bullet and installed Lion on my Macbook Pro. Mac OS X Lion released almost four months ago and comes with some interesting features. You can read about them in detail here. What I’m going to write about here are some of the hurdles I had to overcome. Perhaps when it’s time for you to upgrade, you won’t have to experience them. Of course, YMMV.
Install XCode.appin your Applications folder. You then have to install
Install XCode.appto install XCode. Not confusing at all.
I could have easily upgraded to Lion from Snow Leopard, but I wanted a clean slate. I collected a lot of cruft over the year and a half and I thought it would be educationally rewarding to set up the development environment again, but this time without a guide. I also wanted a clean dot-file slate, learn about the commands in each dot-file instead of just accepting them and taking them for granted.
If you already have Time Machine set up (or similar backup software), then you’re already ahead of the game. I did not have any backup software installed/enabled (hard drives can fail???), so I manually copied directories and files over to my home NAS. I didn’t have a lot of stuff that I cared to back up, so this was a rather easy process.
Since I planned to wipe out the hard drive and start fresh, I needed to store the Lion installer on a USB thumb drive. Apple offers a USB thumb drive option, but why pay $69 when you can do it for free? There are many guides out there with detailed instructions on how to extract the core file from Lion installer and transfer it to your USB thumb drive.
I rebooted the computer, inserted the thumb drive, and held down the Option key. I proceeded to the Disk Utility and wiped out my hard drive. Then when I attempted to install Mac OS X Lion, I was greeted with S.M.A.R.T. errors message. If you can’t select the hard drive to tell the Lion installer the destination of your install, then chances are, you have S.M.A.R.T. errors. I googled this issue and lots of people have reported the same issue. The hard drive worked fine in Snow Leopard, Lion does not want to do anything with it.
I ordered a new hard drive from Amazon.com, waited a day for it to arrive, then tried again. No S.M.A.R.T. errors. BOOM, it let me proceed and within 15 minutes, Lion was on my machine.
First thing I did was check for Software Updates because I was well aware of the updates that had come in post Lion release date. After that, I proceeded to install software I care about (in alphabetical order):
The following tools were installed to aid my development needs:
I know some hate rvm and prefer rbenv, but I’m fine with it. I installed homebrew next. Homebrew requires XCode, and I knew
that beforehand; what I didn’t know about is that it doesn’t like XCode 4.2. The App Store only has version 4.2 (and higher
when you read this post at a later date). The homebrew notes has the link
to version 4.1. Download and install. Here’s a caveat: the dmg contains an installer. The installer installs
Install XCode.app in your Applications folder. You’ll need to run that installer to finally get XCode installed.
This confused me to no end for an hour.
Git, ctags, zsh, and tmux installations were straight forward. Homebrew is your friend. Unfortunately though, homebrew does
not have a vim formula (and probably does not plan to).
I had to install this from scratch. This is probably the
long-winded process of getting it installed, but I digress: Update: You can brew install it.
brew install https://raw.github.com/adamv/homebrew-alt/master/duplicates/vim.rb
I have been using MacVim for the past year and a half, but since this summer have been using it exclusively. I’m taking a step further and switch to vim, so I can use it in tmux sessions, over ssh, etc. I used to use AkitaOnRails’ vimfiles, but decided to adopt this vimfiles instead. I’m using this setup right now to write this blog post and so far I’m loving it.
Caveats to getting the vimfiles to work. If you’re a fan of wincent’s Command-T, then this may be troublesome. The plugin kept segfaulting, so I removed it completely from the bundle directory. This is even after compiling Command-T using system ruby. The vimfiles uses FuzzyFinder anyway, so it’s not the end of the world.
The vim that came with Lion will not work with vim plugins that need Ruby support. You can easily check this by checking
the version (
vim --version). It should have a plus next to
ruby. So if FuzzyFinder is not working for you, it’s
ruby was not enabled for the vim you have.
Hope you enjoyed the TL;DR post. I know I wasn’t very descriptive on every step of the process, so if you have any questions, let me know in the comments.
