Never an issue on my iMac, but I do love updates. Curious thing is this IS an issue on my 2011 Macbook Pro. Minor inconvenience if anything. Going back to the fact that I do LOVE updates.

I have this issue with my Fall 2010 11" MBA. When I open the lid from sleep sometimes the wifi won't connect or will connect to another network. I hope this issue is addressed for my model as well.

Well, this would be useful if I hadn't long since given up on wireless with the iMac and hooked up an ethernet cable.

It fixes it! Finally! I thought it was something on just my system. It also fixes finding wi-fi on reboot as well. No more manually trying to get on a wi-fi network that takes up to 30 seconds after waking from sleep. Now it is automatically reconnecting to my wi-fi network and loading a web page within 5 seconds of wake up.

I found that this update caused some of my music applications to fail, specifically MOTU Digital Performer and the EastWest "Play" virtual instrument.

Fortunately, I make nightly backups, which is what is restoring right now.

Oh well...


Your machine was likely already broken, or broke for a completely unrelated cause. Look at the update in Pacifist, it hardly changes anything and does not touch anything that is related to those applications, at all...

"This update resolves an issue that may cause an iMac to not automatically connect to a known Wi-Fi network after waking from sleep."

Read the article text, if you've got this issue this is relevant to you.

If you've got slow wifi, wifi that drops out while the Mac is awake, grey screens or no Internet once connected I don't see why this update or this topic applies to you, it's most likely a different unrelated problem(hardware probably in most cases imop).

Personally I have been using the frustrating "disable Bluetooth" fix on my MBA and that's worked fine. I've now had chance to try the 10.7.4 beta and it seems like it might be finally fixed...
