Mactracker is a piece of software that gives you access to detailed information about Apple products. It also enables you to compare the specifications of 2 different Apple devices, find out information about your own iOS gadgets, and check details regarding the latest OS versions.
This utility might prove to be of good use if you plan on acquiring a newer version of your Apple device and wish to compare its specifications with the ones of your current gadget. Simply select the products in question from the program's records and hit the Command+K keys.
Besides offering you information about Apple devices like desktop computers, laptops, smartphones or tablets, this tool also gives you access to details about macOS versions, Wi-Fi products, early Apple systems, and many others.
What's more, its latest version provides you with info about the newest Apple technology: iPhone 8, iPhone 8 Plus, Apple TV 4K, macOS 10.13 High Sierra, iOS 11, watchOS 4, tvOS 11, etc.
My only problem with this utility is the fact that it occasionally runs slow, especially when selecting products from the list and loading their correspondent info.
Still, the app comes without a price and provides you with many important details regarding the Apple technology.
