[General] What crashes a Mac user?

[Tal'Rarity]

I am working on a crash guide and would like to know the problems for mac users, I appreciate any help on this. Hope some of you know something so we can form some kind of guide for this to help others.

Thanks in advance.

I know that there's terrain deformation issues for Mac users or was.

Textures with dummy mipmaps (to save filesize) crash macs. The lowest available mipmap must always be 1x1 or 1x2 in size.

Cool, thanks Zwiebelchen. The fix for textures is making the mipmap 1x1 or 1x2?

I think the problem is it Being a Mac =P

But on a serious note: Can't something to do with alpha channels on icons also cause it to crash?

No, I think for Mac compat you need all mipmaps, not just the last one.

Joke...

Either...

Or...

Although not technically a crash, there is a difference between Windows and Mac versions of WC3 as to how the terrain is deformed and produced from deformation natives. This means GetLocationZ can return different results for the same terrain geometry.

This is not limited to mac however as Windows users will be affected by the following. Walkable destructibles will have different animation positions based on visibility. Walkable models may have different geometry based on model quality setting. Terrain deformations might have different quality based on physics quality settings.

What is known is that MAC terrain deformations even at the same visual settings are still different in some way from Windows ones.

Would one not include them all? I would imagine most loaders would either expect all or none seeing how it makes no sense to have only some. Also there are apparently better mipmap algorithms one can use that are generally not applied for automatically created mipmaps during load.

The simplest way to generate these textures is by successive averaging; however, more sophisticated algorithms (perhaps based on signal processing and Fourier transforms) can also be used.

Otherwise there would never be any need for mipmaps in a texture format in the first place.

Why would vex's map optimizer crash a Mac user? Also does programs like http://www.wc3c.net/showthread.php?t=101586 cause problems for macs as well?

Vexorian's optimizer doesn't cause any problems on a Mac. Wc3SLKOpt will cause a crash if the ZIP BLP is set to mip1 or mip2 AFAIK.

Wc3SLKOpt seems to be causing some kind of crash for mac's, there's also an icon/texture causing a crash so I think the two are related.
