New Mac experiencing multiple minor issues

<< 12) The “spinning rainbow circle” is appearing more and more. >>

That is the WAIT cursor.

The wait cursor, often referred to as the "spinning beach ball," appears on macOS when an application is busy processing tasks and cannot quickly respond to user input. It indicates that the application is performing a lengthy operation or may be unresponsive due to issues like heavy resource usage.

Other unexpected causes are things like too many Apps left open, and not QUIT, even if they do not have active windows. Not enough real RAM memory can contribute. Less than 20 percent disk space FREE on the Boot Drive may contribute.

By far the easiest way to cause poor performance, instability, overheating and crashing is to install ANY third-party speeder-uppers, Cleaners, Optimizers, Third-party Virus scanners, Bit Torrent, or a VPN that you installed yourself. 

Activity Monitor, which you already mentioned, may be useful in determining exactly why you need to wait.

<< 13)   On web browsers, when pressing Shift + down, instead of highlighting the text, it just takes the page down more quickly. >>

I don't think this is a Mac issue, but rather an issue of certain web pages.

Every web page is free to provide its own response to those buttons. Some work like a lot of other web pages, some have invented their own meanings for those buttons.

You can almost always double-click to select a word, triple-click to select a line (or possibly a sentence or paragraph) or drag across the text that you want to select.

if you bought DIRECT from Apple, not from a Reseller of any description, you typically have 14 days to return your Apple products for a full-value refund.

if you would like Users on this forum to discuss and possibly help you solve your issues, I suggest you break that long list into related sub-lists, and post them separately. This will allow users with deeper expertise in ONE area to assist you.

if you would like help from Apple Support, use the link at the bottom of every forum page:

<< 9) Safari and WhatsApp (and some other apps) are preventing sleep mac activity monitor. >>

is likely closely related tomthis one:

<< 8) It warms up sometimes, even when put to sleep. >>

when you close the lid on your Mac, that is a REQUEST to Sleep.

If any apps are still running that prevent sleep, your Mac will continue to run with the lid closed, and Not sleep at all. Running with the lid closed does not cool as well as with lid open, so your Mac may get warm. This is because your request to sleep could not be satisfied, and your Mac continues to run normally with the lid closed.

Macs are the product of thousands of person-years of hand-made hardware and software. The complexity of the overall system is mind-boggling.

Your list does not appear to my experienced eye to show any signs of pervasive failures or pervasive problems, but rather, several clumps of related issues. I think each of those areas have solutions.

--------

I do know that Font, language, and writing-system problems with Microsoft Apps are extremely common, because Microsoft tends to implement these settings and changes inside their own Apps, IGNORING Mac system settings, Fonts, and preferences.

I work exclusively in US English, so I have no applicable experience to address your system seeming to slip back and forth between Arabic and English from time to time. But we DO have Readers who work in multiple languages daily, and a few that work deeply in language encoding, translation, and use of Fonts. They may know rules and 'tricks' that can quiet the apparent chaos in that area. A query with a more-focused title in that regard would get you far more focused and detailed information.

--------

Wi-Fi is an area that for most users, "just works".

But I and others can address some issues in that area

<< 1) After being disconnected from Wi-Fi, every time asks for the password >>

System Settings > Network > Wi-Fi > ...

Setting "Ask to Join networks" will ADD networks that you previously joined (and their saved passwords) to a list of networks to potentially be joined every time your Mac wakes up.

the list of Known network is available under the (Advanced) button there.

You can remove your neighbors' Router from that list, for example.

<< 5) Shows connected to WiFi but not really connected. >>

what EXACTLY is the manifestation of that?

do you get "self-assigned" IP address?

do you get an error message?

are some web sites unreachable? are ANY web sites reachable?

is your system TIME correct within five minutes?

Any web browser's logic for closing is the same:

The "Red" button closes the core, clearing the open tabs.

The "quit: button only takes the browser away from our eyes, while all open sessions remain there for the next recall.

I understand it.

My problem is that sometimes even the "quit" function closes all my open sessions and behaves like the "Red" close button.

And I didn't get your point about being logged in.

I am not trying to reload. Naturally (and if chosen in the web browser's settings), whatever previous sessions should reopen when restarting the browser. That happens to me sometimes, and sometimes it doesn't, especially in Safari and Firefox. I dont dare to push the Quit button!

I think you are attributing FAR more "smarts" to the Internet connection than it deserves.

When you;

• close a Window (with one or more Tabs open) with the red button, or

• Quit a browser, or

• Restart your Mac with the "re-Open all Windows from the last session ..."

... your Mac remembers only a VERY small set of things:

• the URL of the web page, including any subdirectories or flags explicitly added to the URL

• the cookies and databases that web site set up one your Mac.

That is the end of the list.

The text and images of the page itself is generally NOT saved, and if the web site simply throws an error message, that is not a defect -- that is what it was programmed to do.

<< For #5, I see the Wi-Fi icon as white (= connected), but I still can't access the internet. No modification I have made. No self-assigned IP, and no error message. Any website unreachable (would it matter since it should be a black-and-white matter?).

My system's time is exactly correct. >>

when this happens when you are at home, it could indicate a Wi-Fi issue that we can pursue with a little more information from you.

When this happens when you are trying to access a Public Wi-Fi,

Launch a browser and enter this easy to remember all-numeric IP address:

1.1.1.1 

in the address bar,  and press return.

If you get the CloudFlare** splash page, your internet is working, but DNS lookup may not be working.

**CloudFlare is NOT part of the solution, they just own the easiest to remember all-numeric IP Address (Does not require a DNS lookup.).

if instead, you get a login page, that is also likely working -- the Public Wi-Fi has intercepted your web page request for 1.1.1.1 and sent you their login page instead. Just follow their directions, and all may be well soon.

Regarding 3, this is a bug to report to Apple, see

https://discussions.apple.com/thread/256247006?sortBy=oldest_first

Regarding 4 and 11, MS apps can have some annoying behaviors relating to keyboard and proofing tools settings, better to ask in the MS forums devoted to those products.

<< 2)  Restore from the last session doesn’t work for Firefox and Safari or if it works sometimes, it is not reliable.   >>

I think you may be mis-understanding that function.

When active, Safari and/or Firefox will re-load the URLs of the web pages that were open before, ONLY.

They DO NOT and CAN NOT restore the previous session or state.

Things are likely to be different, due to the passage of time. You are likely not logged in (you can't be, because time has passed and you were likely auto logged out). In some cases, attempting to re-load some pages will simply produce an error because they are only available to logged-in users, and you will appear to be a different and not logged-in user.

<< For #1, I'm not connected to any Wi-Fi network other than mine. When my router dies (for any reason) and the Mac disconnects, after the connection is re-established (as indicated by the Mac's Wi-Fi icon), a small window appears asking for my Wi-Fi password, and yes, my Wi-Fi is listed under the known networks. >>

Seeing your network shown in that box says it is among the 'currently detected' networks.

Seeing that box at all says that you did not enable "Ask to join... " so that your Mac was told to attempt to re-connect automatically, when any Network on your list of Known (and password-saved) networks is detected.

counter example:

on my phone, I have a LONG list of known network. That list includes my home network.

That list also includes every coffee shop, doctor's and dentist's office Wi-Fi I have ever visited.

Since I am old, that list is quite long.

Regarding 7, this is presumably connected to some 3rd party app or setting on your machine. Do neither shift nor caps lock work to type C right here? Also in chrome or Firefox?
