Apple may well have an update on the way that fixes the 4GB memory problem
affecting at least some new MacBooks and MacBook Pros, but it apparently isn't the firmware update that was just released yesterday
. According to jkOnTheRun, while the update appeared to have remedied the problem initially, the freezing eventually returned and, once again, going back to 3GB proved to be the only way to get the laptop back into working condition. Of course, Apple never claimed that the update would fix this particular problem, but it seems that there's an increasing number of people waiting to hear something about the matter straight from the company.
