How to Delete iCloud on Mac in 2 Easy Ways!
There are a multitude of reasons why you might want to delete your iCloud account from your computer. Perhaps you recently paired it up with another device and the iCloud synchronization is not working correctly, or maybe you just don’t like everything Apple anymore. The choice is yours, but if you do decide to go ahead and remove your iCloud account from your machine then there are a few things that we need to cover first, such as:
The good news is that once you have successfully deleted your iCloud Account from your computer, all of the services will continue to function in exactly the same way when they were before; however this does not mean that you won’t be unable to sync certain data through iCloud.
Now that your iCloud account has been removed, this should enable you to be able to sync with Gmail & Exchange accounts while still retaining any important information that was previously backed up using iCloud. However if you also want to remove these additional services then please carry out the following steps:
Select Other for the type of account you are adding. You can then add any other email accounts that do not rely on Apple’s Mail software (e.g., Gmail). If you already have one or more accounts set up using Apple’s mail service, make sure to delete these first otherwise it will conflict with whatever else you are trying to achieve here.
Once all desired accounts have been added, open Google Calendar and go to Preferences… → Accounts tab. Now repeat steps 3–5 by following this path: Preferences → Accounts tab → Delete Account
Click the words, then go to your Apple ID account page. Look for the Data & Privacy option at the bottom of the screen and click Manage Your Privacy. To delete your account, click Delete Account. Request to Delete Your Account is where you should do so.
Yes, If you don’t want to have iCloud on your PC any longer, it’s easy to remove. You won’t be able to access any of your iCloud files or photographs directly on your PC anymore. If you need a file/photo from iCloud on your PC, go to iCloud.com in your browser.
At the bottom of the page, click Sign Out. To launch Control Panel, press and hold down the Windows key on your keyboard. Type “Control Panel” and hit Enter to open it. Uninstall a program by clicking Uninstall a program in Control Panel. Select iCloud from the drop-down menu at the top of the window then Change it by clicking Change. Select Remove and click Next to confirm that you want to remove iCloud. Yes
To remove an iCloud account from a device, simply hit “Delete Account.” To do so on a Mac, go to System Preferences and select iCloud before clicking the “Sign Out” button. The following notifications will be identical whether you press the “Delete Account” button on an iOS device or the “Sign Out” button on a Mac.
