I have just updated the OS to High Sierra, Rhino for Mac is now running so slow and clunky, just moving the cursor and drawing poly lines is not good. Since updating the OS I have also noticed that I keep getting a system preferences warning to update the Cuda Nvidia driver, I have updated to the latest driver, yet I keep getting this message pop up when starting up my MacBook Pro, is this whats affecting Rhino to run so slow ??
Release version or WIP? Please copy and post system info from Rhino.
both Rhino release version and WIP, will post system info later, just wondered if anyone else has had similar issues

Any difference in Safe Mode?
I’ll try try restarting in safe mode and running Rhino later, here is a screenshot of the warning I keep getting to update cuda , I have updated and there is no newer version ?? Maybe the problem is here with the Nvidia card ?? I’m not really knowledgable with all that kind of stuff 
Via MacOS update or by direct download from NVidia?
Rhino shows com.nvidia.CUDA (1.1.0) and Nvidia 9.0.222. This could be real or just confusing numerical nomenclature. Would not be the first time. Other possibilities too.
If you let MacOS do the update, might try direct NVidia download and run again. Released this month for 10.13.x
BTW - I have not installed Rhino onto a 10.13.x box yet…
Safe Mode is an attempt to isolate issue, but may or may not indicate anything.
thats the driver I already installed directly from Nvidia today 
, just checked a few forums, seems this window popping up is a common problem, and many others having same issue for other software like Adobe stuff
Bummer. 
I have a test box of 10.13.1. If I have time next week will load Rhino and report back.
Little solace now, but in general, on a production box, wait at least 3-6 months to update to new major release (new OS name) or perhaps until x.x.3 or x.x.4 minimum.
Unfortunatly, Apple is ‘in-your-face’ with their annual releases…
@ec2638 seems to be running fine now 
, very strange indeed 
@milezee That’s good news! All good here too!
I did just load WIP (5E292w) onto the fresh 10.13.1 box. Opened a relatively complex model, rotated it around, drew a few boxes, and all seemed normal in a few minute test.
My test differs from your system, I assume, in that it is ‘nuke and pave’ clean, in that the drive was formatted APFS and 10.13.1 was laid down direct from the Apple retail 10.13.1 installer.
I did not not install the CUDA 9.0.222 driver, and the OS has not asked for it. I assume CUDA 9.x is not there from the OS installer, but I have not dug any deeper into 10.13.1.
@dan Does Rhino Mac need/want/benefit the CUDA 9.0.222 driver at present?
Thanks
No, it does not.
