Do not install the newest Adobe Flash Player 10 unless you know you can uninstall it if things go wrong. Apparently there have been issues on top of issues with this release and the biggest of all is it can cause full lock ups on computers possibly causing a reboot.
I ran into this yesterday after installing an update to Safari and then Adobe Flash 10. YouTube would work, but Fancast, Hulu, SciFi and more would quite literally lock the browser up hard.
This was the first “Windows” like issue I have had on Mac OS X in 4 years. Things just always work. An app might crash here and there, but never, never are there “Windows” type problems with random slow downs and misconfigurations or OS lockups. Never. Truth.
So, I did some debugging and noticed it was happening in Firefox 3 also. Ah ha! Not the browser or OS at all, but probably a plugin. OK. We can fix this. Long story short, tested, checked and solved by uninstalling Adobe Flash 10 and reinstalling Adobe Flash 9.
I normally would not say anything to you folks about this, but apparently this is not isolated and is actually quite a big issue. Checking just a few boards and looking at some stuff I can from Apple, shows clearly this is widespread. I even called one of my buds on the IE team and they also are having a ton of reports of lock ups and full system hangs.
To make matters worse, if you don’t have a backup of Adobe Flash 9 you might have problems getting it from Adobe or others. One thing is for sure, make certain you uninstall Flash 10 before you go to Adobe to try and download Flash 9.
To fix this lock up issue follow these instructions and the links provided.
1. Get the uninstaller for Adobe Flash 10 and check out the knowledge base article for detailed instructions by system type. You must use Adobe’s uninstaller or it probably will not work.
2. Download Adobe Flash 9 and install it.
As with all bugs, you may not be affected. After this happened I got curious and spent about 2 hours testing other machines. Hey, I don’t have to do this kind of thing usually and it was the first issue in over 4 years so, what the hay.
I managed to reproduce the effect of hanging or freezing on 4 out of 4 computers and on Safari, Firefox and Internet Explorer on all 4 machines. That is 12 reproductions with 100% reproducibility on multiple, different operating systems and hardware.
- My OS X Leopard MacBook Air
- My OS X Leopard MacBook Pro
- My Vista Ultimate MacBook Pro
- My Windows XP Sony Vaio
So for the record every machine I have is affected the same. Well, almost the same, Windows usually crashes IE or Firefox with the problem but a couple times it froze so bad I had to reboot. Everything stopped responding. OS X never stopped responding.
Oh and one more thing, YouTube does not seem to show this behavior on any machine. The only thing I found with YouTube is it was a bit slower on Vista than normal. Fancast and SciFi were 100% repeatable.
Now you see why this is so serious. I have to watch those Galactica webisodes, The Face of the Enemy.
Well, I think I rode that horse about as far as I could. Remember, you may not have a problem. However, if I can reproduce something 100% on 4 different computers running different operating systems on all 3 browser on each I figured it would be best to post some instructions on how to repair the problem.
