We know that Icrontic has a small but fervent core of Rails/Mac developers, so this piece from Julie Cameron of MetaSpring on upgrading the Rails environment for the release of Snow Leopard is particularly timely.
Now that Apple has released their new OS, Snow Leopard, thousands of devoted Mac web developers are jumping on the upgrade bandwagon – and for good reason! Snow Leopard has implemented a ton of nice little tweaks to make your Mac faster and more reliable, resulting in a much smoother development environment.
One of the biggest changes in Snow Leopard is the shift to 64-bit computing. While this change will make for huge speed increases and optimized memory usage, it also means that you’ll need to upgrade or re-compile any 32-bit applications or libraries still lingering around (that is, if you installed Snow Leopard on top of your existing system rather than doing a clean install).
So to make your lives easier, I’ve put together a list of all the steps that I had to take to get back down to business. These instructions should work for most Mac/Rails setups, though you may need to tweak certain steps or take a few more should errors arise.
The whole piece is easy to digest and comes jam packed with links to great content from other developers, so if you’d like to put a certain spotted kitty on Rails, give it a try.
