I'm wary of upgrading to the first point release of new OSX releases. There's always something that seems to break my dev environment.

broke my homebrew and gave me weird warnings in tmux :(

dang sorry to hear that man :/ that's exactly why I don't want to upgrade just yet.

I guess it's time to roll the dice and see how much of homebrew and my build environments break.

Dice rolled, lots broken (it seems). Now to start trying to fix things...

Exactly what I'm doing.

None of the features I see really interest me, it's just stuff that integrates with their other services none of which I don't use anyways.

I'm really confused. There already were two posts today regarding the new MacOS release:

If you're using a Razer mouse, don't upgrade :) Causes kernel panics and a reboot loop (remove RazerHid kext to fix and launchctl remove all com.razer stuff, then replace Synapse with something like SteerMouse).

This was sure a weird one - everything works fine until you start moving a mouse at which point you catch a kernel panic.

List of petty annoyances:

- Can't reinstall haskell-stack from Homebrew.

- Karabiner can no longer remap keyboard keys, and seems to be no longer being maintained because development moved to another project.

- CPU is stuck at 100% doing some sort of "optimization"

- Macs Fan Control stops/starts controlling fans randomly

I've had 0 issues with Homebrew since upgrading at beta one. The only reason it broke with last years OS update to 10.11 was because of rootless.

Also note: They removed support for PPTP vpn. While good for security may screw you if that's all you can use.

Well, this broke Junos Pulse and Outlook 2013 sending

Do I need it? Not sure.

Do I want it? Way ahead of you!

Update: Outlook Unclear
