For example, they cannot access data that is owned by other user-installed applications on the device. There is a very extensive set of privacy controls contained within iOS with options to control apps' ability to access a wide variety of permissions such as the camera, contacts, background app refresh, cellular data, and access to other data and services. Most of the code in iOS, including third-party applications, runs as the "mobile" user which does not have root privileges. This ensures that system files and other iOS system resources remain hidden and inaccessible to user-installed applications. Companies can apply to Apple for enterprise developer certificates. These can be used to sign apps such that iOS will install them directly (sometimes called "sideloading"), without the app needing to be distributed via the App Store. The terms under which they are granted make clear that they are only to be used for companies who wish to distribute apps directly to their employees.
Want to spend a bit less? Check out the more affordable desktop computer options recommended further down the page. Read our Dell XPS Desktop 8950 review. If you're looking for the most affordable Mac out there, the news is good nearly all around. Apple's smallest desktop computer was among the first to get upgraded to the lightning-fast M1 processor, which runs rings around comparable Intel-powered Macs in terms of speed and performance. Unlike MacBook laptops, the Mini boasts legacy ports like USB-A and HDMI, too. The 256GB and 512GB models will run you $699 and $899, respectively, at the Apple Store, but the good news is that they're now frequently on sale at other retailers for $50 to $100 less. More and more Mac apps are adding compatibility for the M1 platform, and Apple's Rosetta 2 software runs most legacy apps in a fairly speedy compatibility mode, but if you still want native Intel support, a Core i5 version of the Mini remains in the line for $1,099.
