Macs include the OS on a separate quantity of the disk. It’s read-only, and cryptographically sealed in order that it can’t be modified. Solely Apple’s installers have the certificates to have the ability to replace this quantity.
Every little thing else — apps that you simply obtain, your paperwork, all of your preferences, settings, caches, temp recordsdata — all of them go on one other quantity of the disk, referred to as “Knowledge”. (Often “Macintosh HD – Knowledge”.)
Because of the division, merely erasing the Knowledge quantity restores your Mac to a ‘manufacturing facility state’.
There may be usually by no means a must erase the entire disk and reinstall the OS.
Not like some PC producers, Apple doesn’t promote area on the disk to third-party software program, so there is no such thing as a ‘bloatware’ as such.
While you first get your Mac, it would run the Setup Assistant, the place you may arrange your consumer account and switch any information from one other pc. As soon as that is executed, you may head to System Settings > Normal > Software program Replace, and see if there is a new OS model. If there’s, simply click on “set up”, and it’ll undergo the motions.
Additionally in contrast to Home windows, there is just one OS ‘picture’**, which works for all supported Macs. There are not any extra driver packages or no matter that want updating and putting in.
One different level: Macs do not really want any ‘upkeep’ to enhance efficiency. And you do not want any utility apps that promise to keep up your Mac.
** Effectively, okay: if Apple releases a model new mannequin after an OS launch, then it could want a particular construct that features new drivers for that new {hardware}. Nonetheless, the subsequent basic launch of the OS will then have these drivers included.
