RAM and MacBook crashes
Issues with RAM may be behind problems affecting some MacBook buyers, anecdotes indicate. Select MacBooks, including ones newly-received from Apple, appear to be crashing within minutes or hours of booting. The lock-ups also appear to ignore the intensity of whatever software a user may choose to run, and diagnoses made using Apple Hardware Test reveal no discernible hardware errors.
The root of the dilemma may lie with expanded RAM options, whether from Apple itself or third-party companies such as Crucial or OWC. Systems with the default 2GB of RAM are said to be stable, but introducing another 2GB may lead to crashing. Some users report a fix after replacing a notebook's RAM entirely, but Apple is also known to be accepting returns of MacBooks with crashes, so long as the official return time window is in force. The company has not responded with an explanation or solution to crashes.
