Workaround for the 27 inch iMac Flash lag?

This week I finally received my 27in i7 and I experienced huge lags while browsing the Internet with firefox. I decided to plug in directly instead of using wireless and that fixed it completely for me. I had my old 24in NOT running SL and had no issues with wireless ever.

I've had lots of beachball action on my '07 MacBook Pro, both with Leopard and Snow Leopard, so its not a strictly a 27" issue, nor is it 10.5 or 10.6 specific.
Mostly my problems pop up in Safari because its my default browser, but also when I try in Firefox. Sometimes I get a flash 10 script warning, but usually not.
Disk Utility gives me DOZENS of un-repairable permissions errors in 'Library/Internet plug-ins/Flash player/...' plus a pair of SUID file problems that 'will not be repaired'.
I've uninstalled and reinstalled Flash 10 5 or 6 times but the issues keep coming back. Snow Leopard seemed to solve things, but only for a few weeks and the problems returned. The permission problems go away after the uninstall, so all evidence points at Flash.
I don't know where to go from here, but a HDD format and virgin reinstall seems like the next step.

Please Apple and Adobe, sit in a room together and work your shit out!

Try to launch your Safari in 32-bits mode. It solved the high CPU usage problem in my Macbook. Funny thing is that, the so called "Flash player (Safari internet plug-in)" didn't show in Activity Monitor when running Safari in 32-bits.

haha i don't really care b/c there's a big blue area right where i live!

I have a 27" 3.06ghz C2D - I have my mac permanently connected to wireless. This slowdown isn't just for flash, has nothing to do with it in my opinion, it really is workstation wide (and really does seem more prevalent in both Firefox and Safari).

Just read the above suggestion to disable airport and re-enable it, and immediately the machine was again up to speed. No doubt in my mind that this will be a software related issue, as the same behaviour (ie. hogging resources, slowing the machine down) are not seem on my Windows 7 partition in boot camp.

There should be an update out soon by Apple - it's now finally good to know that it's not just me that is having the problems system wide (as most pages will tell you it's only flash related.)

Cheers!

Hello All,

I have a new 27" iMac. Even it never was as bad as some readers experienced, I was looking for improvement. I have read somewhere on Apple Forum an advice to disable "Hardware Acceleration" for Flash plugin. I think it helped a lot. I wonder if more people can benefit from the advice.

To do that, load a page with flash object in Safari. Right (control) click the object and select "Settings..." from the pop-up menu. Select the first tab (on the bottom) and un-tick "Enable hardware acceleration". Click the "Close" button.

I hope it will help to some.

This is also happening on my new Macbook Pro 13" loaded with Snow Leopard. Just purchased it, and it is lagging on flash pages. I never had this problem on my other Macbook before this one running just Leopard. SO yes, it's a software issue, an issue with Snow Leopard. Come on, Apple. Post a fix for this now!!

I think the problem is more likely that Flash simply sucks on the Mac. Always has, and probably always will.

I have a 27" iMac bought Sunday (after the TUAW warning/post, oops). The system slow down happened three times, once with my Parallels VM (not flash!). Both times it happened after my internet research, turning off Airport resolved the issue instantly. Airport is my only internet connection. Both times, I instantly tuned Airport back on. The first time I tried this Pandora never stopped; it never reached the end of its buffer. My unsubstantiated theory is that it has to do with sleep, airport, and processor intensive tasks. I have a Apple Care issue open, I haven't heard back. I hope Apple figures it out soon!

I had this problem on my 27inch iMac. I uninstalled anything flash related then reinstalled 2 days ago and everything has been working perfect since. Im pretty sure this is totally software related. Maybe a problem with SL or 64bit vs 32bit etc. Hopefully they resolve this soon.
