Dear all,

I just switched to a new 2016 Macbook Pro and noticed that R is very slow when used over the R app. Using R via the terminal is significantly faster.
Especially, drawing figures in quartz is really slow and sometimes the following error message is printed – but this might be unrelated to the speed issue:

IMKInputSession presentFunctionRowItemTextInputViewWithEndpoint:completionHandler: : [self textInputContext]=0x0 *NO* NSRemoteViewController to client, NSError=Error Domain=NSCocoaErrorDomain Code=4099 "The connection from pid 0 was invalidated from this process." UserInfo={NSDebugDescription=The connection from pid 0 was invalidated from this process.}, com.apple.inputmethod.EmojiFunctionRowItem


Is this a known issue related to Sierra and/or the new Macbook Pros? Are there any workarounds or fixes?


Thanks for any suggestions!
