I had both releases running on my Mid-2014 MacBook Pro (16GB, 1TB SSD) and had constant issues whenever a heavy disk access process occurred, such as copying a file or installing something. Basically, everything would freeze for about 5 seconds. The mouse would still move, but anything I clicked on would not respond. Then, it would all back again and any delayed clicks would fire. Due to this, I've gone back to 8.1 where it is completely stable. Something tells me it's a driver issue - both times (Windows 8.1 and 10) I'm installing the Bootcamp 5.1 drivers. Has anyone else experienced this on a Mac? Anyone running on Bootcamp WITHOUT issues? Any thoughts or advice? Thanks all!
