Some media and some rumors suggest that Apple seems to be disregarding some of its products and possibly focus on others such as mobile devices that have made them so successful, that is, smartphones and tablets. Although it does seem that next year we will see some renewed products such as the iMac, Mac Pro and Mac Mini, for the moment these have been in the background for the Cupertino company.
That's why some wonder if your bet is iOS and your energy efficient products, why not license macOS? That would allow many other manufacturers of computer equipment, such as HP, ASUS, Dell, Acer, etc., could assemble computers and provide another alternative to the almost ubiquitous Windows. That is, to be able to have desktop PCs and laptops with macOS installed. In my opinion, this will not be the case, at least in the short term.
This move maybe it would hurt Linux more, since it would have a new competition that now it does not have in the sense that you cannot install a macOS on any non-Apple device, therefore either you buy an Apple device or you forget about macOS. And I say in principle because you already know that this is not true at all, there are modified images of the Apple system to be able to install on non-Apple computers (see Hackintosh).
Regardless of whether it would affect Linux more or less and whether they end up doing it or not, which I repeat, I don't think they will, at least in a few years to come. It is true that Apple is pouring many resources into iOS and in developing its A-Serial SoCs. The latest designs of these chips come to have quite good performances to be of low consumption. This has led some to suggest that Apple could stop relying on Intel microprocessors as it did in its day with Motorola and IBM chips (breaking the famous AIM).
Anyway ... all rumors. What do you think?
