Language switching is different for different operating systems. If in Windows you are accustomed to one keyboard shortcut, then when installing another OS, you will have to get used to the new method of switching certain functions.

PCKeyboardHack program
Instructions
Step 1
While in the text editing window, press the Alt + Space key combination. Check if the layout switch worked. The role of the alt="Image" key in the iMac is basically the CMND button (it can be used to denote it).
Step 2
If you want to assign the keyboard language change to a different command key, download and install the PCKeyboardHack utility. After installing it, restart your operating system. When it boots up, open the system settings menu in this program.
Step 3
Find the item responsible for the settings and operation of the keyboard in your computer. In the open window, click on the modifier key configuration menu and for Caps Lock, cancel any action.
Step 4
Save your changes, but without closing the window, go to the shortcut settings tab. Open the "Keyboard and input text" item and find the previous input source in the menu window for selecting the previous input source, there may also be "Next", but there is no fundamental difference between them.
Step 5
Double-click on the combination that is used for this command. Then press the F19 button. In some cases, it crashes and the window becomes inactive, in which case just repeat the sequence of operation. If everything worked out right for you, then remove the Simulate F19 icon if you are using it (in case there is no such key in the keyboard), since you will no longer need it.
Step 6
Return to the main menu of system settings in the PCKeyboardHack program. Check the box on the left side of the Change Caps Lock screen, and on the right, change the value from 51 to 80. After that, save all the changes made using the application and restart the operating system. Check if switching layouts using Caps Lock now works.
