Apple is warning at least some people replacing custom MacBook Pros about extended wait times, says AppleInsider. Representatives are reportedly quoting 4 to 6 weeks as an average replacement time, but in extreme cases the wait may be as much as 8 weeks. The company is allegedly willing to offer refunds if the delay is too long. Alternate options given to people are said to include switching to a stock configuration, or getting a computer from a retail store.
