No go - don't stress over it though, not like it's super important :tongue: ``` systems-samm-imac ~ % cat /Users/samm/Library/Logs/Homebrew/gls/01.xcodebuild 2015-09-08 15:33:38 +1000 xcodebuild -project gls.xcodeproj SYMROOT=build Build settings from...

OK issue with 10.11 BETA 6, looks to be related to the rootless setting which can no longer be disabled? ``` samm-mbp ~/git/mac-pixel-clock-patch % ./macPixelClockPatcher.command Detected unpatched IOKit on 10.11...

SwitchresX does work in 10.11 though - I'm currently on Beta 2 about to upgrade to 3 later today. ``` samm-mbp ~ % md5 -q /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit 516bea2790cd6bfcb41959aa66122623 ```

Thanks :)

Here is the md5 for 10.11 beta 5: ``` md5 -q /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit git:master* 798a8e362e89e38e8f9cf6e59fda5184 ``` Thanks,

FYI for this to work on 10.11, you need to disable rootless (don't do this unless you understand the potential security implications): ``` sudo nvram boot-args="rootless=0" ```

``` samm-mb ~ % md5 -q /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit 798a8e362e89e38e8f9cf6e59fda5184 ``` Latest dev beta (5?) as of 8/8/2015

I find that 4k is limited to 30hz on any device 2+ years old.

FYI - This is the card I'll be using, and what @ross-w is already using in his own trials of implementing a pi-kvm.
