If you've been updating your Mac OS to the latest version macOS High Sierra and the download is pretty damn slow, though you have a fast internet connection. We've tried figuring out what is the cause of the problem or there are secret hidden settings to enable to fasten its download speed. Upon checking and testing different ways to resolve the problem, we've come in to solution. The problem is when you're connected into a 2.4Ghz Wifi and your macbook tends to download pretty low or limited if you're connected to it. The solution is you must have a Wi-Fi that has 5G capable, most fibr home wifi has this feature and if you connect your Macbook pro laptop into it, your download speed will fasten same as your internet bandwidth. On our experiment, when we're using 2.4GHz connection we barely gets 100Kb/s to 200Kb/s download speed and it takes 5 hours to complete the macOS High Siera Updates which is the size is 5.20 GB. But when connected to 5GHz we get the full bandwidth of our internet connection which is 3.5Mb/s and it only takes 30 minutes to complete the update. These are some of the issue of the newer macbook pro's laptop and if you have other alternative to fasten your internet connection, please leave a comment down below!
