The last time I bought low-voltage processor was several years ago. It couldn't handler running as the presenter when teaching online using something like GoToMeeting. The screen sharing and audio was just too much for it - the CPU would sit at 100% and the whole machine would lock up. Have any of you tried this with the new 2017 MacBook? I would likely go with i7/16GB to minimize the risk of having a problem, but I'd feel more confident if I hear some of you have done it successfully Thank you!
