When I open a website like ebay or zillow, all of the page info is lining up on the left side of the screen - so I figured I need to update my software. However, when I hit update from the apple icon I get an error that says "App store cannot verify a secure connection". It asks if I want to go ahead and if I do the screen just flashes. Help!
MacBook Pro, OS X Mountain Lion (10.8.3)
There's another way to update your Mac's software. (Going by your profile v10.8.3)
Install the OS X Mountain Lion Update v10.8.4 (Combo)
Then restart your Mac.
To avoid the flashing screen, open System Preferences > Accessibilty then select Audio on the left.
Deselect: Flash the screen when an alert occurs
If after the combo is installed and you still have problems with pages loading, if you are using Safari, empty the Safari cache by pressing Command + Option + E on your keyboard.
Quit and relaunch Safari. See if that made a difference.

Take each of the following steps that you haven't already tried until the issue is resolved. Back up all data before making any changes.
Step 1
Check the status of the service. If it's down, wait tor it to come back up. There may be a localized outage, even if the status indicator is green.
Step 2
Check that the date (including the year) and time shown by your system clock are correct.
Step 3
Restart your router and broadband device, if different.
Step 4
If you connect to the Internet through an HTTPS or SOCKS proxy server, follow the instructions in this support article, or deselect the proxy entirely.
Step 5
Boot in safe mode and try again.
Step 6
Make sure Parental Controls aren't active for your account.
Step 7
Follow the instructions in this support article to change your DNS settings.
Step 8
If possible, test on a different network, such as a public Wi-Fi hotspot or the cellular network of your phone.
Step 9
Launch the Keychain Access application. In the Keychains list, there should be an item named System. If not, select
from the menu bar and add the following item:
/Library/Keychains/System.keychain
Close the inspection window. You'll be prompted for your administrator password to update the settings. Revert all the certificates with non-default trust settings.
From the menu bar, select
Keychain Access ▹ Preferences ▹ Certificates
There are three menus in the window. Change the selection in the top two to Best attempt, and in the bottom one to CRL.
Next, select the login keychain. Delete any expired or otherwise invalid certificates.
Log out, log back in, and test.
Step 10
Launch the Activity Monitor application. Select All Processes from the menu in the toolbar of the Activity Monitor window, if not already selected. Enter "ocspd" (without the quotes) in the "Filter" text field. Is a process with that name listed?
If not, back up all data, then triple-click the line of text below on this page to select it:
/var/db/crls
Copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Move all the files in the folder that opens to the Trash. You’ll be prompted for your administrator password. Reboot, empty the Trash, and test.
Step 11
If you've moved to a different country, select
Store ▹ View My Account
from the App Store menu bar, then click
Change Country or Region
and update your billing information.
