The disk has an operating system (macOS Big Sur), and user data (apps, etc). And since you only have one disk, this is your startup disk: all 500GB. A Mac with two disks will have the storage divided between them. The Mac drive with the OS on it is the startup disk while the other drive is just used for storage of files. The logical reason would be that there is some fault on your usual OS volume that prevent it from booting, or it is being instructed to do so. Given that you state that you get to this recovery screen regardless of what volume you select to boot from, it seems the former is more likely.
The Dock is a prominent feature of the graphical user interface of macOS. It is used to launch applications and to switch between running applications. The Dock is also a prominent feature of macOS's predecessor NeXTSTEP and OpenStep operating systems. The earliest known implementations of a dock are found in operating systems such as RISC OS and NeXTSTEP. iOS has its own version of the Dock for the iPhone and iPod Touch, as does iPadOS for the iPad.
Apple applied for a US patent for the design of the Dock in 1999 and was granted the patent in October 2008, nearly a decade later.[1] Any application can be dragged and dropped onto the Dock to add it to the dock, and any application can be dragged from the dock to remove it, except for Finder and Trash, which are permanent fixtures as the leftmost and rightmost items (or highest and lowest items if the Dock is vertically oriented), respectively. Part of the macOS Core Services, Dock.app is located at /System/Library/CoreServices/.
Overview[edit]
OpenStep Dock
In NeXTSTEP and OpenStep, the Dock is an application launcher that holds icons for frequently used programs. The icon for the Workspace Manager and the Recycler are always visible. The Dock indicates if a program is not running by showing an ellipsis below its icon. If the program is running, there isn't an ellipsis on the icon. In macOS, running applications have been variously identified by a small black triangle (Mac OS X 10.0-10.4) a blue-tinted luminous dot (Mac OS X 10.5-10.7), a horizontal light bar (OS X 10.8 and 10.9), and a simple black or white dot (OS X 10.10-present).
In macOS, however, the Dock is used as a repository for any program or file in the operating system. It can hold any number of items and resizes them dynamically to fit while using magnification to better view smaller items. By default, it appears on the bottom edge of the screen, but it can also instead be placed on the left or right edges of the screen if the user wishes. Applications that do not normally keep icons in the Dock will still appear there when running and remain until they are quit. These features are unlike those of the dock in the NeXT operating systems where the capacity of the Dock is dependent on display resolution. This may be an attempt to recover some Shelf functionality since macOS inherits no other such technology from NeXTSTEP. (Minimal Shelf functionality has been implemented in the Finder.)
The changes to the dock bring its functionality also close to that of Apple's Newton OSButton Bar, as found in the MessagePad 2x00 series and the likes. Applications could be dragged in and out of the Extras Drawer, a Finder-like app, onto the bar. Also, when the screen was put into landscape mode, the user could choose to position the Button Bar at the right or left side of the screen, just like the Dock in macOS.
The macOS Dock also has extended menus that control applications without making them visible on screen. On most applications it has simple options such as Quit, Keep In Dock, Remove From Dock, and other options, though some applications use these menus for other purposes, such as iTunes, which uses this menu as a way for a user to control certain playback options. Other Applications include changing the status of an online alias (MSN, AIM/iChat etc.) or automatically saving the changes that have been made in a document (There is no current application with this feature made available for macOS). Docklings (in Mac OS X 10.4 or earlier) can also be opened by using the right-mouse button, if the mouse has one, but most of the time either clicking and holding or control-click will bring the menu up.
Stacks in grid view.
In Mac OS X Leopard, docklings were replaced by Stacks. Stacks 'stack' files into a small organized folder on the Dock, and they can be opened by left-clicking.Stacks could be shown in three ways: a 'fan', a 'grid', or a 'list', which is similar to docklings. In grid view, the folders in that stack can be opened directly in that stack without the need to open Finder.
In iOS, the dock is used to store applications and, since iOS 4, folders containing applications. Unlike the macOS dock, a maximum of 4 icons can be placed in the dock on the iPhone and the iPod Touch. The maximum for the iPad however is 16 icons (13 apps and 3 recently opened apps). The size of the dock on iOS cannot be changed.
When an application on the Dock is launched by clicking on it, it will jump until the software is finished loading. Additionally, when an application requires attention from a user, it will jump even higher until its icon is clicked and the user attends to its demands.

Design[edit]
The dock, as it appears in OS X 10.8 to 10.9
The original version of the dock, found in Mac OS X Public Beta to 10.0, presents a flat white translucent interface with the Aqua styled pinstripes. The dock found in Mac OS X 10.1 to 10.4 removes the pinstripes, but otherwise is identical. Mac OS X 10.5 to 10.7 presents the applications on a three-dimensional glassy surface from a perspective instead of the traditional flat one, resembling Sun Microsystems' Project Looking Glass application dock.[2] OS X 10.8 to 10.9 changes the look to resemble frosted glass with rounded corners. OS X 10.10 and later revert to a two-dimensional appearance, similar to Mac OS X 10.4, although more translucent and with a iOS 7 blur effect.
In iPhone OS 1 to 3, the dock used a metal look which looks similar to the front of the Power Mac G5 (2003-2005) and Mac Pro(2006-2012 or 2019-). iPhone OS 3.2 for iPad and iOS 4 to 6 adopted the dock design from Mac OS X 10.5 to 10.7 which was used until iOS 7, which uses a similar dock from Mac OS X Tiger but with iOS 7 styled blur effects.[citation needed] In iOS 11, the dock for the iPad and iPhone X is redesigned to more resemble the macOS dock.[3][4]
Related software[edit]
The classic Mac OS does have a dock-like application called Launcher, which was first introduced with Macintosh Performa models in 1993 and later included as part of System 7.5.1. It performs the same basic function.[5] Also, add-ons such as DragThing added a dock for users of earlier versions.
Microsoft implemented a simplified dock feature in Windows 98 with the Quick Launch toolbar and this feature remained until Windows 7, where it was replaced by the Superbar, which implements functionality similar to the macOS Dock.
Various docks are also used in Linux and BSD. Some examples are Window Maker (which emulates the look and feel of the NeXTstep GUI), Docky, and Avant Window Navigator, KXDocker (amongst others) for KDE and various other gdesklet/adesklets docks, AfterStep's Wharf (a derivation from the NeXTstep UI), iTask NG (a module used with some Enlightenment-based Linux distributions such as gOS) and Blackbox's Slit.
Criticism[edit]
Bruce Tognazzini, a usability consultant who worked for Apple in the 1980s and 1990s before Mac OS X was developed, wrote an article in 2001 listing ten problems he saw with the Dock. This article was updated in 2004, removing two of the original criticisms and adding a new one. One of his concerns was that the Dock uses too much screen space. Another was that icons only show their labels when the pointer hovers over them, so similar-looking folders, files, and windows are difficult to distinguish. Tognazzini also criticized the fact that when icons are dragged out of the Dock, they vanish with no easy way to get them back; he called this behavior 'object annihilation'.[6]
John Siracusa, writing for Ars Technica, also pointed out some issues with the Dock around the releases of Mac OS X Public Beta in 2000. He noted that because the Dock is centered, adding and removing icons changes the location of the other icons.[7] In a review of Mac OS X v10.0 the following year, he also noted that the Dock does far too many tasks than it should for optimum ease-of-use, including launching apps, switching apps, opening files, and holding minimized windows.[8] Siracusa further criticized the Dock after the release of Mac OS X v10.5, noting that it was made less usable for the sake of eye-candy. Siracusa criticized the 3D look and reflections, the faint blue indicator for open applications, and less distinguishable files and folders.[9]
Thom Holwerda, a managing editor OSNews, stated some concerns with the Dock, including the facts that it grows in both directions, holds the Trash icon, and has no persistent labels. Holwerda also criticized the revised Dock appearance in Mac OS X v10.5.[10]

The rainbow-colored circle is a painful sight to see for Mac users. If you’re lucky it disappears in a few seconds, but more often it remains for minutes, leaving you helplessly locked out of the app or your whole Mac. Since it’s not always clear how to deal with with the wheeling cursor or what caused it in the first place, let’s break it all down. In this article we’ll take a look at what is the spinning beach ball, why and when it shows up, and what you can do about it.
What is a spinning color wheel?
Initially, it’s a system indicator. It’s official name is the Spinning Wait Cursor, not so official — the Spinning Beach Ball of Death or SBBOD. The ball signifies that your Mac cannot handle all the tasks given to it at this moment.
Every app on your Mac has a so-called window server. When an app receives more events than it can process, the window server automatically shows you the spinning ball. It usually takes about 4 seconds for the app to decide that it’s non-responsive.
Why does the Mac spinning wheel of death appear?
Well, the reasons are countless. First, it can be a stand-alone issue with a certain app. Second, it could be faulty hardware or insufficient RAM. We’ll go over each possible issue and see how it can be fixed, depending on the cause. Sometimes, the only way out it getting a new Mac, but most of the cases can be fixed with the right software or system commands.
How to stop the spinning ball on Mac?
In case you just need unlock one frozen application, that’s a job for Force Quit.
To fix an application stuck with a spinning cursor right now:
- Click the Apple icon in the top left corner.
- Choose Force Quit (or press cmd+alt+esc).
- Select the app that won’t respond.
- Click Force Quit.
Simply shutting down the process is a brutal way of problem solving and it doesn’t address the issue that caused the freezing. It could have been an accidental glitch in the program, but if it keeps freezing or spreads further to other software and services, you need to look deeper.
What if the application keeps freezing when you open it again?
Reset or reinstall the freezing application. Macs don’t have a proper uninstaller and moving applications to the Trash bin leaves plenty of app leftovers. Some of them could be the reason why the spinning wheel showed up, so if you leave them the issue will stay.
How to reset a Mac app to its default settings or uninstall it
There are two ways to reset apps: one would be to use application’s own preferences or settings and look for reset options there. But in case the app won’t let you do that (because it keeps freezing), you can turn to third-party solutions, like CleanMyMac X for instance. It’s a handy app for Mac maintenance and cleaning with plenty of useful tools, including reset and uninstallation.
- Download CleanMyMac X, an app for Mac maintenance.
- Open it and click on the Uninstaller.
- Select the app you need to reset from the list.
- Click on the small arrow next to the application icon
- Click Applications Reset.
If the beach ball keeps rolling when you use the app again, reinstall it completely by pressing Uninstall instead or Reset. Remember, simply moving the app to the Trash doesn’t do the trick, since its leftover files remain on your hard drive.

Important: if you have a licence for the paid app, makes sure to save the number somewhere.
What if your whole Mac becomes unresponsive?
Possible issue: Overworked processor
One of the reasons for the wheel to show up could be that your Mac is getting old. You can figure out if that’s the case by checking the CPU usage. To check the CPU usage, turn to Activity monitor. Find it in the Applications/Utilities folder or run a Spotlight search. Or, if you have CleanMyMac X, use it’s Menu in the top bar.
The bottom table shows System load in percentage. If it’s way above 50% and remains there for long, especially without any specific reason like games or heavy rendering programs, this might be the signal your processor is the bottleneck.

Fix: If your processor is overworking regularly, only buying a new Mac will fix the problem entirely. Sorry.
Possible issue: Low disk space

You don’t even need to have a full startup disk to see the nasty ball. Just a heavily loaded hard drive, with lots of large files can already cause troubles with loading.
Fix: Hard drive cleanup. Thankfully, that’s an easy task. You can get CleanMyMac X and in free up tons of space in a few minutes. With CleanMyMac you don’t need to dig into folders and look for files you don’t need, the app will find and sort them, plus all the system junk your Mac has been accumulating for months.
Possible issue: Insufficient RAM
Another possible hardware issue is insufficient Random Access Memory. To figure out if you need more RAM, open the Activity Monitor again. It’s in the Applications/Utilities folder. In the Memory tab, you can see Memory pressure table with a graph. If the graph is red and your memory is constantly strained under all the running apps, you’ve found the problem.
Fix: You can upgrade RAM by buying and installing more of it. It’s usually enough to have 8 GB for most tasks and applications, apart from heavy video rendering and the likes. Here’s a detailed guide on how to upgrade RAM on Mac.
That’s about it concerning the spinning beach ball and how to deal with it. We hope this guide has been of help and you’ll stop the spinning wheel of death on your Mac once and for all.
