I just upgraded from OS X 10.11.6 to macOS 10.12 developer beta 8. I notice that I can't use "shift + left click" to select text any more. Is that a known issue or if there is any settings to set this? Thanks. --- Post Merged, Aug 30, 2016 --- It seems like the problem on my Corsair K65 RGB. It was not designed to work in macOS. However, I managed to use it in macOS using a third party drive ckb.
