Hello there, sdfcvoh.
It seem you are having issues with your built-in camera being recognized on your MacBook Pro. The following Knowledge Base article offers up some great pointers for pinpointing the issue. You've done some great troubleshooting on your own that is covered in this article, but you may find additional steps for troubleshooting:
How to Troubleshoot iSight
Important: Follow these instructions in order. Test the camera between steps to see if the issue is resolved.
These steps are for iSight cameras that are built into a computer, such as the iMac G5 (iSight) or later, the MacBook, or MacBook Pro.
- See if the issue is application-specific.
Try another application (iSight works with applications like iChat, PhotoBooth, and iMovie HD 6) to see if the iSight camera exhibits the same behavior in all applications. If it only happens in one application, try reinstalling that application.
- See if the issue is user-specific.
Test your iSight camera in another user account. If the issue only occurs in one user, the issue would be isolated to user settings.
- Find out if the computer recognizes the iSight
Check System Profiler (in the Utilities folder, inside the Applications folder). Under the USB header, check to see if the iSight camera is detected.
- Reset SMC or PMU
Reset your computer's SMC or PMU, and then check System Profiler again. (SMC reset instructions for iMac G5 (iSight), Intel-based iMacs; PMU reset instructions for MacBook and MacBook Pro.)
If your built-in iSight camera is still not behaving correctly after trying all these steps, you may need to contact Apple or an Apple-Authorized Service Provider for service.
If you need some help testing in another user, this article has the information you're looking for:
How to test an issue in another user account on your Mac
If you're seeing unexpected behavior on your Mac try these steps first:
Try searching Apple's knowledge base for the specific symptom or alert message you're seeing. There might be simpler steps you can take to resolve the issue.
Try starting your Mac in Safe Mode. Restart your computer. Hold the Shift key when you hear the startup sound. Release the Shift key when you see the Apple logo appear. This starts your Mac in Safe Mode. Safe mode performs a directory check of your startup disk, and removes some cache data. After your Mac finishes starting up, restart your Mac normally (without holding the Shift key) and see if the issue is resolved.
Make sure your software is up to date. The issue you're seeing might be addressed by installing available updates.
Check to see where the issue happens. If an issue appears before you see your desktop, it's less likely that it's related to a user account or setting. If an issue happens with a website, see if pages from other websites load correctly first. There might be an issue with the site and not your Mac.
You can figure out if unexpected behavior is related to user file or setting by trying to reproduce the issue from another user account. This process includes creating a new user account, logging in to it, and testing for the issue.
Create a test user account
- From the Apple menu, choose System Preferences.
- Click the Users & Groups icon in the System Preferences window.
- Click the lock icon, then enter an administrator name and password.
- Click the Add button ( + ) below the list of users.
- Choose a type of user from the New Account pop-up menu.
- Give the user a full name, account name, and password.
- Click OK.
- Close the System Preferences window.
If there are documents from your original user account that you want to test with, place a copy of these items in the Shared folder in the Users folder. Press the Option key while dragging a file to this folder to create a copy.
Log in to the test user account
Log out of your current user account by choosing Log Out from the Apple menu, then log in to the new account you created. If you're prompted to sign in with your iCloud account or Apple ID when you log in, skip this step.
Try reproducing the issue
Try the same steps that caused the unexpected behavior to appear before. For example, if you were unable to print, try printing from this user account. If you were unable to connect to the Internet, try browsing a website from this user account.
If you were using any specific settings that testing depends on (such as using a specific email account or iCloud account) set up the same account in the test user. For email and most other settings you can use the Internet Accounts pane in System Preferences to set up these kinds of accounts. If files from your home folder are needed for testing, copy them to Shared folder in the Users folder (/Users/Shared). After logging in as the test user, copy these items to the same location in the test user's home folder to test with.
If performing the same steps in a test user account doesn't result in the same unexpected behavior, you most likely don't need to reinstall any apps or OS X.
- If an issue only happens in one app, check the app's documentation or support website for instructions on troubleshooting specific preference or setting files.
- If you need help with a specific alert message or issue, search the Apple Support website for the text of the alert message you're seeing.
If the same unexpected behavior happens in more than one user account on your Mac, try checking for software or hardware issues.
After you've finished testing, log out of the test account by choosing Log Out from the Apple menu. Then log in to your original user account.
You can remove the test user account you created when you're done. Make sure you're completely finished testing, and that you don't need any of the files or settings you created or copied there before you remove it.
If you need more help with a software or hardware issue, contact Apple Support. If you work with an Advisor, Genius, or service provider to resolve an issue, be sure to mention any steps you've already tried and the results. Also mention any alert messages you've seen as part of the issue. You can take a screenshot of any messages that appear so you can refer to them later.
Thanks for reaching out to Apple Support Communities.
Cheers.
