Editor crashes on Mac

[TheAdder]

I just tried to create a new dungeon in the editor on Grimrock 2 on my 2010 iMac. The editor loaded, I created a new dungeon, pressed Create and everything appeared normally. I drew a few floors and walls and pressed save. Everything fine. But, later when I reloaded the editor and opened the dungeon I created, the dungeon appears in the window but as soon as I click anywhere in the window the spinning beachball appears and the editor crashes with the error below.

I then opened the Grimrock 1 editor and loaded a dungeon I last worked on in 2013. Again, the dungeon appeared in the window but then clicking anywhere crashes the editor. What's changed on my system since 2013? Well, obviously OSX has updated several times but software should be compatible - and that wouldn't explain the Grimrock 2 editor crashing when I only downloaded the game a few days ago.

What gives? How do I load my old Grimrock 1 dungeon in the editor or start a new Grimrock 2 one?

What's changed on my system since 2013? Well, obviously OSX has updated several times but software should be compatible

Apple ain't Microsoft in that regard. Under OS X each new security patch can mean that something ceases to work.

[TheAdder]

Well I doubt that very much, especially as I'm a programmer and the only thing that has ever broken in any of my programs was they changed the colour of prompt text in a text field between versions and now you can't see where it says "Type a command". But the software didn't break. If an OS update broke existing software, they'd be sued out of existence by every software company on the planet.

But none of this explains why software downloaded last week doesn't work the first time I try it.

[TheAdder]

Ok. It seems to be obvious what's happening - Neither Grimrock 1 and 2 is compatible with the full screen mode of OSX Yosemite, which is odd as the game only came out a few weeks ago for Mac and Yosemite has been around since last year. The issue seems to be, looking at the error log, that the crash occurs during a window resize operation after reloading a dungeon, even though I am not manually performing one, so presumably window resize is called as part of the window loading. Whatever the reason, the editor crashes after reloading any dungeon editor file.

The following is what the screen looks like if you bring up the editor and manually press the maximise/full screen button. Obviously, this needs to be fixed and a new version of both Grimrock games released that are compatible with the screen resize

Just to clarify, I've been running Grimrock 2 since the beta on OS X Yosemite and it works just fine for me. With hardware from 2010, I would make sure you are running on Low Graphics mode and it's worth trying it with Low Resolution textures too (just to see). Apple have never really made machines for gaming (a few more recent models are okay-ish) so I expect that an iMac from 2010 is going to be pushing it in terms of Video Memory for all of the assets in the game.

[TheAdder]

The problem is the editor, the game runs superbly - as does World of Warcraft at 2900x1400 resolution without a pause.

To be clear - the Grimrock 1 editor also now does the same thing, but only on Yosemite. Both editors run flawlessly on my less powerful MacBook running the previous OS.

Aye, it could be the gfx hardware, perhaps even just their drivers.
In 2010 Apple was all into ATI cards so maybe checking the AMD page for OS X drivers might help.

[JohnWordsworth]

By 'running Grimrock 2 on Yosemite', I do mean the editor! I made most of the GUI Toolkit on OSX which took maybe 30 hours and I only ever had crashes when it was my fault.

I would definitely look into GFX card stuff though. I wouldn't expect my 2009 iMac to run Grimrock 2 as the ATI card in that had only 512MB RAM. Luckily, I don't use that old beast for much any more!

[TheAdder]

As I said, there cannot be anything wrong with the graphics because I've played the game through from start to finish and there were no graphics problems, speed issues or crashes. Furthermore, the editor works perfectly if I load the game up, go into the editor, start a new dungeon and spend hours designing it - no problems at all. The problem only happens if I reload the dungeon later, then it locks up and then crashes on loading.

That's not a graphic issue, is it? Graphics don't decide they're going to work perfectly while using the software as long as you haven't saved and reloaded. That makes no sense whatsoever :/

And also, clearly a graphic issue wouldn't stop Grimrock 1 from loading a dungeon in the editor which it previously loaded without problems in Mavericks. Grimrock 1 is 3 years old.

You miss the point. When the same software does no longer run on the same hardware there must have been a substancial change within the underlying OS oder driver support. 3 years ago there was Mountain Lion and the drivers supplied by Apple back then were different.

Simplest thing to do is to re-install Mountain Lion on a spare disk and check the games and the editors on your hardware.
