    They were supposed to fix a wifi bug but instead its created new issues for me. After a wake from sleep, wifi will not work correctly and performance will be beyond bad, super slow. Turning wifi off/on doesn't fix it.

    The only way to bring wifi back to normal after sleep is to restart entirely!

    Late '13 13" rMBP.

    Might have fixed it - repaired disk permissions and rebuilt my kextcache. Maybe something didn't go correctly during the update process.

    Though I had the issue with wifi both times after leaving it asleep overnight, this test I just did was only after a few minutes. I don't think there's 2 separate sleep states anymore on the SSD based platforms like the MBA/rMBPs, so it shouldn't matter how long it was asleep?
