I'm upgrading my Macbook to El Capitan. Is there a developer guide somewhere with hints? There used to be things with brew not working etc.

I just did this and used these: https://ohthehugemanatee.org/blog/2015/10/01/how-i-got-el-capitain-working-with-my-developer-tools/ https://jimlindley.com/blog/yosemite-upgrade-homebrew-tips/

@alexmiller: thanks

Just finished the upgrade. Everything seems to 'just work' until now.
