Programs crash, getting Exception Codes: EXC_I386_DIV (divide by zero)

I get this in the error report that gets sent to Apple but still have no solutions. Happens in many different programs including the finder. Not consistently, can go the whole day without it happening, then it happens.

This is in all reports, only thing that looks the same no matter what program crashes. Exception Codes: EXC I386DIV (divide by zero)

I have done all the usual things, disk utility, third party utilities, reinstalled system OS, etc.

Mac Intel tower, Mac OS X (10.6.5), 8GB RAM 1TB HD

Does the diagnostic disk just check hardware only, no software?


That's right. Given the wide variety of software, it's hard to perform "diagnostics" on that.

Does anyone know what that error (Exception Codes: EXC I386DIV (divide by zero) means?


It means that a program is dividing two numbers, but one of them (the divisor) happens to be zero, when presumably it shouldn't be. This in turn can result from sloppy programming or, more commonly, but corrupted data.

There are several ways to identifying the cause of such crashes. These first two may make routine use of a Mac difficult.

- Boot into "safe mode" by holding down a "shift" key during the boot process. Among other things this prevents some third-party software from loading. If any of that is causing your problem, this should eliminate the crashing. However, the lack of third-party software may prevent some of your programs from working properly. Note that "safe mode" booting isn't intended to "fix" the problem but only to help isolate the problem.

- Create a second user and work in that user for a while. (Since in that mode you won't have access to files in your original user's folder, you may have to move some of them over via the "Shared" user folder.) If the crashes stop, then the problem is due to something in the original user's folder.

- Launch the Console utility. In the left column navigate to FILES -> ~/Library/Logs -> CrashReporter. Look for a crash report for one of the crashing applications. Post the content here and someone should be able to help you decipher it.

If you are getting a divide by zero error in the Finder, there is something corrupt on your system. Since the disk verifies ok, besides re-istalling the OS, I'm not sure what might fix it.

When you get that in the Finder, what are you doing? From what device to what device? e.g. "copying a file from Western Digital MyBook to internal hard drive."

As posted, this is either very sloppy programming or something is corrupted. Could also be RAM. If it is failing, it might be returning wrong address locations and resulting in Div by zero.

Panics are usually hardware, and running AHT is a good first start. It finds some errors but not all, but Extended Test and Loop anyway. Follow up with Rember/Memtest (if you have a lot of RAM, pull half and run, then other half). Memory errors are harder and stability and stress tests even on RAM can go for hours.

A clean install of the OS can give you ground zero to rule out and start to look for other issues.

If it is a new Mac Pro then it default boots to 64-bit and needs 64-bit drivers as well.

If AHT kicks out an error, then you know you need to take it in and while we can guess, we don't have a list of what those codes are or mean.

And do clone your system when it is working, then don't just verify, but boot from another drive, and in addition to using Apple DU First Aid, throw in Disk Warrior to the mix and regular preventative maintenance and repair.
If you have a crash/freeze etc then be sure to at a minimum do SAFE BOOT (shift key until desktop appears), as the directory and cache files are usually damaged or in need of repair or have bad contents.
When the problem is resolved, a clean solid OS as a foundation.

Right now, I would not trust verify's results, I would assume one or more frezes caused trouble and only add new problems to make matters worse, and until those are resolved you can't peel back the onion to see what is underneath.
