How to fix error in Mac OS X El Capitan and Yosemite: "This copy of Mac OS X can't be verified." 

Getting Error "403 Forbidden" when Signing in through apple ID

For everyone that’s experiencing the Apple ID sign in pop-up or the 403 error, I have finally found a potential fix. Do not get upset if this doesn’t work, as I’m only intending to help, not provide invalid information. Please try this and tell me if it fixed the error. You must upgrade your Mac to the latest Mac OS X version it supports. I have been able to fix this problem everyone’s having by doing that. Also, a person had success after upgrading. Here’s how I recommend doing the process: Acquire a USB flash drive. It’s usually better to use a 16 GB one or more. 1, Google the top OS X version for your Mac. It may be El Capitan, or High Sierra. An example might be “What is the latest supported macOS version for MacBook Pro 2009”. 2. Find the version, then download the DMG file, or if it’s High Sierra then download via the App Store. I recommend using Apple’s website. If you got the DMG, open it and drag the application into your Applications folder. 3. Once the app is in the Applications folder, open up a blank Terminal window on the Mac. Open the Resources folder of the macOS app you downloaded. This can be done by right clicking on the application in Finder and selecting “Show Package Contents”. Open the Contents folder, then the Resources folder. Locate the createinstallmedia executable in the Resources folder. Type without the quotes “sudo [drag createinstallmedia executable here] -volume [drag USB flash drive here] -applicationpath [drag macOS Application file here]. Follow this command exactly, then press Enter. You will be asked to enter your Mac login password. Enter it. And do not worry if nothing shows up while typing it, as the sudo command doesn’t show any output. Wait for the process to complete. After it’s done, eject the flash drive and shut down the other non-working Mac. Insert the flash drive into the Mac, then press and hold the Option key before you hear the boot chime. Select the flash drive to boot and once you are fully booted you can continue the installation normally. I really hope this helps some people out!
