my mac has been perfect for years, but just today . . . it started with this yellowish 'mask' on the text boxes and drop down menus and the safari page is almost entirely yellow . . . . what gives?? Are there known graphics card issues with the MacBook Pro? How can I get an update for the Graphics Card? I checked for updates and it says there are none . . . how can I get this fixed?
If it's just Safari where you see the mask, might not be the graphics card.
From your Safari menu bar click Safari > Preferences > Extensions. If you have any installed, turn that OFF, quit then relaunch Safari to test.
If it's not an extension issue, select the Security tab in Safari > Prefereces. Deselect: Enable plug ins
Quit then relaunch Safari to test. If the mask disappeared, you need to troubleshoot Safari add ons > Safari: Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues
And check Safari > Preferences > Advanced. Where you see: Style sheet
Click the pop up menu. Select: None Selected
If it's not a plugin or style sheet issue, then run the Apple Hardware Test
