Proper permissions are required for every file in macOS to function correctly, without chmod 755 & chown root:wheel Kexts will not work in macOS
For your reference:
chmod 755 (you allow everyone to read and execute the file, and the file owner is allowed to write to the file as well) chown root:wheel (root is a superuser and wheel is a group of super users)
Before starting any process below, you must Disable System Integrity Protection, but if you have never disabled System Integrity Protection, then you do not need to repair permissions at all.

One way to share information from your Mac is by setting permissions in your folders. As you might expect, permissions control who can use a given folder or any disk (or partition) other than the startup disk.
Why can’t you share the startup disk? Because macOS won’t let you. Why not? Because the startup disk contains the operating system and other stuff that nobody else should have access to.
You can set permissions for
To help you get a better handle on these relationships, a closer look at permissions, owners, and groups is coming right up.
Contemplating permissions
When you consider who can use which folders, three distinct kinds of users exist on the network. Here’s a quick introduction to the different user types:
macOS is the owner of many folders outside the Users folder. If macOS owns it, you can see that “system” is its owner if you select the folder and choose File → Get Info (or press ⌘+I).
Folders that aren’t in the User directories generally belong to system; it’s almost always a bad idea to change the permissions on any folder owned by system.
If you must change permissions on a file or folder, select its icon and choose File → Get Info (⌘+I) and then change the settings in the Sharing & Permissions section at the bottom of the resulting Get Info window. Don’t change permission settings if you’re not absolutely sure of what you’re doing and why. And by all means think twice before deciding to apply changes to all the items in a folder or disk; change permissions on the contents of the wrong folder and you could end up with a mess.
For the purpose of assigning permissions, you can create your own groups the same way you create a user account: Open the Users & Groups System Preferences pane, click the little plus sign, choose Group from the New Account pop-up menu, type the name of the group, and then click the Create Group button.
The group appears in the list of users on the left, and eligible accounts appear with check boxes on the right.
If you want people without an account on this Mac to have access to a file or folder, that file or folder needs to go in your Public folder, where the people you want to see it can log in as guests.
Sharing a folder
Suppose you have a folder you want to share, but it has slightly different rules than those set up for the Public folder, for the Drop Box folder within the Public folder, or for your personal folders. These rules are permissions, and they tell you how much access someone has to your stuff.
Actually, the rules governing Shared and Public folders are permissions, too, but they’re set up for you when macOS is installed.
It is suggested that you share only those folders located in your Home folder (or a folder within it). Because of the way Unix works, the Unix permissions of the enclosing folder can prevent access to a folder for which you do have permissions. If you share only the folders in your Home folder, you’ll never go wrong. If you don’t take this advice, you could wind up having folders that other users can’t access, even though you gave them the appropriate permissions.
By the way, you can set permissions for folders within your Public folder (like the Drop Box folder) that are different from those for the rest of the parent folder.
Don’t forget that anything said about sharing a folder also applies to sharing any disk (or partition) other than your startup disk. Although you can’t explicitly share your startup disk, anyone with administrator access can mount it for sharing from across the network (or Internet).
To share a folder with another user, follow these steps:
