Scratch

Though the problem never occurred, it's great that you've taken the time to share your solution to others! This would be a great topic to make "sticky" if any mods or admins are reading!

Hi, delza.

Thanks for reporting this problem. It does help others.

At least two other people have mentioned this problem with Apple's Parental Control software. It sounds like a bug in the Parental Control software, especially since it crashes the entire computer, which is difficult for a normal application to do. (I would guess that any program that tries to upload a large file to a website the the same parental control settings would also cause a crash.)

If you happen to notice which particular control setting causes the crash, please post here. It would probably help others work around the problem. I will also do some experiments and see if I can reproduce it.

P.S. As you suspected, the messages about the Autorelease pool are harmless. We've been seeing those since the last release, but they do not cause any problems. It appear that a few objects allocated at startup time are not released correctly, but since it's not an ongoing memory leak it doesn't cause any problems.

This always happens to me too. HOWEVER:

1) I do not have parental controls on.
2) It does not crash; it has a kernel panic and displays Terminal-type stuff on the screen, ending with "We are hanging here..."

I'm having the exact same problem on my macbook, so I had to move my file to the family shared computer, and upload it on that computer. I perfer it that way for me.

Hi folks,

Whenever my son tried to share a project recently, his computer crashed.  We're running on a fairly new Intel Mac with the latest version of the OS, all security and stability patches, everything up to date, and the latest version of Scratch.  This was a hard crash, had to restart the machine, and it happened every time.

I know other people have been having this problem too, so wanted to post how we've solved it for now. In one of the forums someone suggested that using the OS X "managed account" could be causing the problem.  So I turned off "managed account" for him and the problem stopped, at least we've been able to successfully share a test project.

There are a couple of further details.  First, my daughter also had a managed account, but with fewer restrictions.  She was not having this problem, but I haven't had time to track down what difference causes the crash.  Second, in the Console there were several warnings coming from Scratch about autoreleasing without an Autorelease pool being in place, just leaking.  These would be memory leaks from using Cocoa incorrectly.  I have no idea if it is related (probably not), but wanted to let the Scratch folk know.

I hope this helps others with the same problem.

Well with me my computer logs me out ever 5 minutes instead of crashing my comuter.

I bet you have to type in the address of the Scratch server into the always allowed sites list. Can someone from the Scratch team tell me the address so I can test my theory?

a beta version of scratch 1.3 is out and I can test to see if it uploads on leopard

I use the same version. Are you with leopard? Scratch might not like it if its not because i use the same version of OS with leapord and intel and it works completely fine.

by the way, SonicMariofan, OMG WHERE IS IT?!??!!?!??!!??!!??! thx

We're not allowed to post links, but you can go to the home page then search "1.3 beta" (don't just search in the forum page because that will only search the forums)

hi! um...i tried 2 download scratch on my computer, it worked, but 1 minute later, it told me 2 abort! dude!!
now im kinda confused. wat do i do? 

Okay, let's back up a bit...when you say "it worked", do you mean you successfully installed Scratch and got it up and running?

When you say "it told me 2 abort" - can you supply the exact words that were in the message?  A screenshot would be even better.

The more details you can provide, the better chance people have of figuring out what is going on.  Thanks.

yeh it waz successfully installed, but afterwards sumthin came up sayin that it might "harm my computer" and that i should abort but i said ignore. so it came back up saying the exact same thing so i think i  had 2 abort.
