What Does a Mac Operator Do?

macOS is a proprietary operating system developed by Apple for the Mac products. macOS is a pre-installed system for Apple's Mac series of products, embodying the purpose of simplicity everywhere.

When Apple Computer released the Mac OS X system, it was announced that

• Full 64-bit technology, you can switch between 64-bit and 32-bit through the third-party Mode Selector.

• Grand Central Dispatch. Helps program compilers use multi-core compilation to enhance software multi-core support.

• Compared to Microsoft Windows, there are some comments about the lack of upgrade prices for macOS; users of the previous version must pay the full price for the new version. Depending on whether macOS retail packaging is considered "upgraded" or not, there is some semantic controversy. On the one hand, it can only be used on Macs. All Macs are sold with some versions of macOS, so it is a controversial upgrade. On the other hand, there is no price difference between upgrades from 9.0 or 10.3 to 10.4. Assume that consumers bought a full license of one of the two versions, that is, at least they did not get any benefit during the upgrade. In addition, after the release of the new version of macOS and when it started to pre-install on new machines to ship, consumers bought Macintosh computers, and usually can get the upgraded version for less ($ 95.95 ~ $ 19.95). At the same time, the upgrade price of Windows actually changes according to the purchase quantity agreement, such as Home Edition vs. Professional Edition, etc., which makes direct price comparison between the editions quite difficult. In some cases, the price of an upgrade to Windows exceeds the price of OS X, so this review is impractical.

  The Open Group also criticized Apple for the use of the word "Unix" in OS X advertising, and Apple has not officially certified the operating system, and his use of this word may constitute trademark violations. Apple claims that they use the word as a general mark and that the cost of obtaining certification will make the operating system more expensive, but The Open Group states that the certification fee for a company is capped at $ 110,000. Even though OS X is Unix-based and features BSD Unix compatibility, it is not compatible with the Single Unix Specification. From OS X Lion already has official UNIX certification.

  However, as of OS X 10.9, macOS has enabled free upgrades. Users can download updates directly from the App Store.
