A new build of the latest beta for the forthcoming OS X Yosemite 10.10.3 was issued on Monday specifically for the few present -- and all future -- owners of the latest 13-inch MacBook Pro. Following the release of the beta last Thursday, which included a warning of a known issue that meant testers should not install it on the new 13-inch MBP, the new build removes that warning -- suggesting that the issue may be fixed.
