same problem here. max6.0.2 osx10.5.8

Have you contacted support? In my experience they get back to you pretty fast.

Overly zealous antivirus software, perhaps?

I'll contact them asap I found what is the bug exactly. I just noticed the GUI was very slow but overdrive wa off. but I don't understand why overdrive was off without changing it. so I wait just to see if i made a mistake or not. and no time to instigate now...

@ark "Overly zealous antivirus software, perhaps? what do you mean by that ? what is a virus on mac ?

fp: Welcome to 2012. Malware and viral infections can and do happen on Mac OS X. Seriously.

2012. already ? oups... I'll wake up sooooon. :-) serioulsly ithappened only with max 6. is it a virus just for max 6 ?

I was simply responding to you question regarding viruses on mac. :)

I don't suppose you've done something like run the Activity Monitor or run "top" from a terminal windw to see what process is sucking cycles. It's unlikely to be a virus

didn't experience it here :-S any answers from support ?

@vade I understtod what you mean. i was joking. sorry.

no time now to investigate more. maybe I've made a mistake. I'll see that later and yes 'll have a look at activity and terminal...

Malware and viruses on Mac OS X? Aside from proof-of-concept exploits, I've only heard about Mac Defender, and the OS quarantines that automatically. Sounds like FUD to me.

I work freelance in the field in post, visual effects and video engineering , I've seen malware/viral infections on Mac OS X systems first hand and have had to deal with them. I am not saying this is the cause, I was merely addressing the sentiment that it does not occur. It does. Wear a rubber.

If by "wear a rubber" you mean "never install or run anything on your Mac if you don't know what it is, especially if it's asking for the admin password" then yes, I agree.

Vade, all due respect, but if you'd found a virus on OS X you'd the first Mac user in 10 years to do so.

Here's a good post that explains the differences between malware, trojans and viruses:

This is veering wildly off topic. That said, I am well aware of the differences between all three various types of nefarious software :)

To be fair i was using the common colloquial term for "virus" - sort of encapsulating worms/malware etc.. To be verbose and nit-pickey, I disagree - there are some pain in the ass infections you can get in some circumstances. There are actual, self propagating 0 interaction viral infections on Mac OS X that exist today, and have for *years*: MS Office has a runtime that hosts Visual Basic scripts. Office documents have been infected with a virus (a real self replicating, on disk, spread to files infection) which can be and has been an issue in any Mac workspace which uses MS office, which also cross infects PC users running windows Office. It makes running Office a pain in the ass. This is so common its almost insane. While this does not infect the OS, it infects files, and the runtime of a major day to day component of the system.

Take a look at http://ithreats.net/ for an idea of how many malware, trojan, worm and remote admin/spyware software gets made for Mac. Many of these exploit issues with default configurations of Safari which unarchives and runs dmgz and zip files i.e.: "secure files".

OSX/Leap-A / OSX.Oomp

Internet worm that spreads through instant messaging via iChat. Infects Power-PC based machines running Mac OS X. The file, latestpics.tgz, masquerades as a jpeg image and sends itself to people on your buddy list.

This one I've seen int the wild too. Most of the issues are strictly speaking malware (i.e. Mac Keeper and all of the ongoing permutations thereof) coming from torrent either downloads or users with non-updated OS'es who have trust issues. My point remains - use a rubber :)

There are lots of threats and risks. Every time I cross the street I'm at risk of being knocked down. Chances are still very low. Before everyone jumps to the conclusion that this is a virus, lets wait for the tests to be done, I.e what does the activity monitor indicate?

Pluralitas non est ponenda sine necessitate!

Who said this was a virus causing Max to be slow? No one, unless my reading comprehension is incredibly poor. Lets drop the stupid virus thing...

cmon guys its not a virus, Im having huge differences in GUI performances between MAX5 and MAX6, MAX6 takes maybe 5 times longer to start up, load heavy patches, open new objects, create and move wires in a heavy patch etc. etc. if not GEN i would still be working on 5, and still flip back and forth for some times because of speed reaction troubles.

What I found useful was to turn off the curved wires animation.
