Apple details fix for 12" MacBook Setup Assistant issues
Apple on Tuesday published a support document to its website detailing workarounds for apparent system stalls some new 12-inch MacBook owners are experiencing during the setup process.
According to Apple, users setting up their new 12-inch MacBook with Retina display are being met with a spinning wheel, known colloquially as the dreaded "spinning beach ball of death," in Mac's Setup Assistant. In certain cases, the system stalls for up to 30 minutes before moving forward, Apple's support documents says.
It appears the issue traces back to user account provisioning on Apple's end, and perhaps iCloud. As noted by Apple, affected users can avoid the delay by moving through Setup Assistant without first connecting to the Internet. Registering user credentials offline of course means no data is sent to Apple's servers for verification or initialization, which seemingly bypasses the issue's root cause.
