MacWiFi helps you answer the question that speed tests don’t: will this connection actually hold up for calls, streaming, browsing, and real work? This a perfect companion for anyone who is always on the go and has to deal with flaky internet connection on a daily basis. I cannot tell you how many times when the internet was slow and then I went and did a speed test and everything looks perfect. But when I attend my call and it is still same shitty connection.
