I won't be making the update for at least a week. Here's the usual
minimalist "info" about the update.
I've updated and am experiencing no problems so far. This update contains a raft of security fixes, though most of them seem to be pretty exotic.
With a fairly clean install and 'fixed' problems, you're probably in the best position to update! I really think most people's problems are from not having a fully 'native' install to begin with. That's been the cause of any problems I've ever had, anyway (and no one else's experience matters!

). Of course, we are always at the mercy of less then perfect checking by for compatibility problems with current software, unfortunately, that sometimes includes Apple's...

I think it's a bit early to start "collecting the voices".

Does this translate to: "You try it, kimmer, and let me know how it goes."
You have a serious and sometimes fatal character fault! You are simply too trusting!!!
You need to practice cynicism or is that senility...
what were we talking about?

1.9.4 fixes a Wi-Fi problem, which I have not experienced.
Nor have I had trouble with it waking from sleep, or the logo problem on startup.
Safari 7.0.5 has some bugs which I dont want to get, so looks like I am going to wait for this update.
Read that YouTube videos wont play sometimes, and there have been a few reports of crashes.
Yes, I will wait till I see the go-ahead here.
I haven't seen any of those problems (YouTube videos play fine for me). The reason I recommend not waiting to install 10.9.4 is that it and the new Safari both fix a bevy of security issues, including issues that can cause exploitation of your Mac by visiting a specially booby-trapped Web site.
Thank you, I dont hit many websites that could be bad, but you never know. Was watching a news site today, and up popped a stupid video, that had nothing to do with the news or weather!I will do the update right now,,,,,,Safari seems faster and everything is just fine.Thanks for the 'courage' to do it.Jane
You don't have to stray far from major good-reputation Web sites to find badness. These days, what malware distributors do is hack legitimate Web sites and plant malware on them. A lot of high-profile Web sites have been hacked and used to spread computer viruses: delta.com, nbc.com, IMDb, ZDnet, the New York Times, and UNICEF's site have all been compromised and used to spread malware at one point or another. It's dangerous to assume you can steer clear of attack just by avoiding dodgy sites. 
Oh, Oh!The videos on the local news channel do not show any more with this new Safari update.We were warned of this. I watch the news first thing in the morning, so this is a pain in the tail-feathers. Will use Chrome or Firefox for the news until Apple fixes this one.Would think Apple would fix this right away, as videos are an important part of the news, and YouTube is very very popular too. Lots of people will be making FF or Chrome their browser of choice for now.
For some people, the Safari update seems to be inadvertently turning off browser plugins or Javascript I've seen a lot of folks complain they can't see videos in Safari after the update, and when they check their preferences, Javascript is off, plugins are off, or both.This didn't happen to me, but it's worth looking in to to see if it's the cause of your problems. Run Safari and go to the Safari->Preferences command. Click Security and make sure "Enable JavaScript" is turned on. Click Extensions and make sure extensions are turned on. For whatever reason, the update seems to be turning them off for some people (but strangely, not for everyone).

JavaScript [...], works fine on my weather sites, and some news sites. But not on my Boston news network. Some work, some dont.
Think about that behavior. If you have javascript enabled in the Safari prefs, it's obviously something that affects individual sites. What do you think you have installed in Safari that might act that way?
Many tools have settings that let you make specific actions based on the site you visit... You might be amazed at what you find simply by exploring your tools/prefs/etc. It's not magic! It's all based on logic and settings/variables, many of which you can change.
