Can you be more specific as of what is slow and how to reproduce it? There was a report that the console UI gets slower in Sierra as the length of the output increases - you can clear the console to avoid that, but the cause is so far unknown, likely related to Xcode 8.3 an Sierra interaction since the problem has not appeared in Mavericks builds for R (try using R 3.3.3 to see if you see the same problem).
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
I have not seen that error, is it reproducible? Cheers, Simon
Is this a known issue related to Sierra and/or the new Macbook Pros? Are there any workarounds or fixes? Thanks for any suggestions!
