    10.9.3 Flickering
    After this upgrade, when I wake my MBA (mid 2012), I have 1 or 2 flickering issues. This only happens if the standby is long.Should I reset PRAM ?

    Go for an SMC reset and see if that helps, if not, come back and we'll try something else

    SMC Reset

    Hope this helps

    Is there any way you could try plugging in an external monitor? If you can then this can help see if it's a graphics card issue (if the flickering remains on the external monitor too) or whether it's a loose connection (the more likely option)

    No, I donīt have a way of connecting an external monitor. What do you mean by loose connection ? Do you think itīs hardware ? It only started after 10.9.3 upgrade and only happens when I wake up the Mac from a long sleep period (hours).

    It could be a random coincidence of a loose connection, but if you're pretty sure it's because of the upgrade then i'd suggest making a full backup and re-installing the OS to see if that clears the problem.

    Try setting your power settings to Performance rather than power preserving, I had the same problem with a Macbook which flickered everytime it switched between GPU's

    Tried the power settings but still no luck. Itīs a random thing, sometimes the flickering is long, the screen goes black for milliseconds, sometimes your barely notice it. But normally always after a few hours of sleep.
