I'm having problems with My MacBook Pro ever since downloading the new OS..

I downloaded

Mac OS X Lion 10.7.2 a few weeks ago, and now I've noticed weird glitches. For instance, my WiFi is SUPER spotty (even though we have RoadRunner top speed), and then I am having these random, yellow QR code-looking things that pop up on my screen whenever I change webpages or open up a new page on my browser (Google Chrome). Any help?

MacBook Pro, Mac OS X (10.7.2)

Well for one get rid of Chrome and use Safari. Chrome is not reliable with Lion and should be avoided. Safari and Firefox are the only two really reliable and effective browsers.


Secondly, reinstall Lion:


Reinstalling Lion Without the Installer


Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.


Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.


When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.


Reinstall Lion: Select Reinstall Lion and click on the Continue button.


Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

I've had problems with Chrome ever since I got my new MBP with Lion pre-installed in July. The two have never worked together for more than a few minutes. It seems that many users have similar problems, but I've read of plenty of users who experience no problems. So far I've got no idea what accounts for the difference. I'm a big fan of Chrome and would like to be able to use it, but it's absolutely impossible in the current configurations. (Nothing special about my Chrome setup either.) I found this thread while looking, for the umpteenth time, for a solution, and thought it was worth adding a note to clarify that the problems are quite real for some of us.
