How to Create a New User Account if You Cannot Access Your Admin Account
I had to sign out of the Skype application on the Mac, click the link to reset my password and select a new Microsoft account password. Then use that one to sign in. It seems the Skype account and Microsoft account are connected, but for some reason, using my correct password on the Skype account stopped working. Step i) Restart your MacBook Pro and immediately press and hold the SHIFT key. Step ii) Release the key when the login window appears. Enter the correct credentials to log in. Step iii) Reboot your MacBook Pro and resolve the MacBook Pro not booting issue. When your MacBook Pro shuts down, hangs, or restarts in Safe Mode, then repair the Mac.
Reboot the computer. At the chime press and hold down the COMMAND-S keys to start into Single-user Mode. You will boot to a black screen with scrolling white text, release the keys and wait until it finishes. Enter the following lines at the command prompt pressing RETURN after each:
mount -uw /
rm /var/db/.applesetupdone
reboot
After you reboot the computer you will be taken to the Setup Assistant. When you get to the point where you are asked to set up your new user account, create a new admin account. Be sure to name this user account something different than the admin user account that already exists on the system. When you finish the Setup Assistant, it will automatically log you into the new account.
You can transfer your files from the old account to the new one. See Transferring files from one User Account to another. Once you have moved all your files into your new account, you can delete the old account using Users & Groups preferences.

How To Refresh Macbook Pro
- First, let’s make sure that there are no network connectivity issues. Make sure that your Mac is connected to the Internet. Check to see if websites load in Safari or in other browsers. If not, you may try the following troubleshooting tips:
- Restart your Mac. (Apple menu > Restart).
- Restart your router/modem (Unplug the power supply, wait 30 seconds and then plug it back in).
- Turn off and on Wi-Fi. (Click the Wi-Fi icon in the menu bar).
- Contact your Internet service provider and confirm that there are no outages.
- Make sure that Apple Mac App Store servers are up and running. Go to Apple’s System Status website and check. It is possible that the App Store service is having issues with its servers or systems. For instance, currently, it is saying “Mac App Store – Completed Maintenance. 1.7% of users were affected. Customers may have been unable to make purchases from the App Store, iTunes Store, iBooks Store, or Mac App Store.” As you can see, the Mac App Store was down for some users, and but now it is fixed. If this the case, there is little you can do. Just wait. You’ll know when the service is working again.
- Launch iTunes. From the top menu bar, click Account and then Sign out. After signing out, sign back in.
- Open the App Store on your Mac and then click Store (top menu bar) and click Sing Out and then sing back in.
- If you are using a VPN or proxy to connect to the Internet, disable them to see if that fixes your problem.
- Update your Mac. Make sure that your operating system is up to date. If you are running macOS Mojave or later, go to System Preferences > Software Update and then click Check for Updates. If there is an update available, update the software on your Mac by following the on-screen instructions. If you are running an earlier version of the macOS software (e.g., macOS High Sierra, etc) then you will need to open the App Store and click Updates.
- On your Mac, make sure that the date and time settings are done correctly. Go to System Preferences > Date & Time to check this. You may also want to check the box for “Set date and time automatically”.
- Restart your Mac in Safe Mode. You can restart your Mac by pressing and holding the Shift key as your Mac starts up (turn off your Mac then turn on and immediately press and hold the Shift key). Try the App Store in Safe Mode and then restart your Mac normally (this time, do not press the Shift key).
- On your Mac, complete the following steps:
- open the Keychain Access app (Applications > Utilities > Keychain Access).
- Click “System Roots”.
- Double Click “DigiCert High Assurance EV root CA”.
- Click “Trust” to expand it.
- Change “When using this certificate” from “Use System Defaults” to “Never Trust”.
- Now restart your Mac.
- And, when your Mac is on, follow the same steps to change “When using this certificate” back to “Use System Defaults”.
- On your Mac, follow these steps:
- Open Finder.
- From the top menu, click Go > Go to Folder and enter the following:
- /var/db/crls/
- Click Go.
- Delete these files: “crlcache.db” and “ocspcache.db”. You may have to enter your admin password.
- And then restart your Mac.
If everything above fails and the issue persists, you could contact Apple.
