Re: Upgrade OS from High Sierra on 2018 iMac

 

¿ªÔÆÌåÓý

I see that I made a mistake. ?When editing the way things looked, I accidentally combined macOS Monterey changes under Big Sur :-(. ?It should have said:

Big Sur:
... New Time Machine backup destinations are formatted as APFS.

Monterey:
... New Shortcuts app.
... Live Text, which allows a user to copy, paste, translate and look up text from images (something that I use almost every day).
... New Passwords Manager
... Visual Look Up makes it easy to identify objects (e.g. cat breeds, dog breeds, etc.) found within user's photos.

I captured most of it from Wikipedia. ?It has a general macOS page, as well as an individual one for almost all macOS versions. ?They have a Changes section on most of the individual macOS version pages. ?They often have extensive references to articles, which can be used to garner more info.

I tried to keep things short, so I omitted some items that may be very pertinent to some folks. ?For example, in Mojave the system drive is automatically converted from HFS+ to APFS, but all on the same volume. ?I didn't include that because she wants to upgrade to the latest possible version for her system, and that includes the automatic split of system and data to separate APFS volumes (Catalina). ?And some folks might find dark mode (Mojave) critical to them. ?(Strangely, I just realized that I always use dark mode on my iPad and iPhone, but not my Mac.) ?

For the latest macOS versions, Apple provides rather complete change lists on their "What's New in ..." webpages, but no references:
Sequoia:?
Sonoma:?
Ventura:?
Monterey:?
Big Sur:?

I have added your notes on the changes to the various OSes to my spreadsheet, Please tell me, how you gathered them up. What search term did you use, or what source?

Interesting, I never found a need for Grab, and did not even notice that Screenshot.app replaced it, since I have been using screenshots keystrokes for ages.

We have slight variations in what we suggest, but it all depends on the individual their needs and their personal workflow.?

A clean install will remove any detritus left over from prior OSes and work, but this amounts to such a small amount of storage.It is almost never an issue, and I can¡¯t cite a documented instance, where any of that left over bits caused a problem or conflict in operation. My opinion is that the leftover bits are the bits that a shared between multiple applications, _probably_ mostly third party software. Apple shares a lot of info and code between things like Contacts, Phone, Mail and Maps. Now think of Microsoft or Adobe, you may have several modules, and remove one. You don¡¯t want to remove the shared code or data, because it would cripple the ones you are keeping, so the uninstallers are written to leave those shared bits.?
