Leopard hang fix

georgetemplemanmac.com · 31 Dec 2007, 13:16

I have been struggling with SU since the purchase of my new mac pro with x1900xt graphics card. The lag during use and the hanging when importing images was unbearable.

I have just installed the fix and repeated the the previous import problem and all seems to be well

Many thanks indeed

The fix is in & working. Thanks for saving my Canadian bacon for the holiday homework. Hopefully there aren't any other Leopard bugs lurking about. Cheers

Inio,

Thanks for the patch! Works fantastic! Nothing was working in SU. Nothing.

Cheers,

Kris

Another big thanks, the fix is working fine. I was going crazy restarting Sketchup every 10 minutes.

BTW, if anyone's wondering 10.5.2 and it's Graphics Update do NOT fix the driver bug that causes this.

Looks like I was right. The attached "input manager" seem to resolve the freezes as far as I can tell. It causes visual artifacts in a few cases when dragging rectangles, but that hopefully isn't too big of an issue.

(bare Input Manager obsoleted by dedicated installer package above).

Here's the source code, if you're interested. If you want the full project, let me know and I'll post it.:


@interface ThawUp ; NSObject 
{
}
@end

#import "APELite.h"
#import "OpenGL/gl.h"
#import "OpenGL/OpenGL.h"

static void (*orig_glClear) (GLbitfield mask) = nil;
static void new_glClear(GLbitfield mask);

static void (*orig_glDrawBuffer) (GLenum mode) = nil;
static void new_glDrawBuffer(GLenum mode);

static BOOL wasFront;

@implementation ThawUp
+ (void) load
{
    if(![[[NSBundle mainBundle] bundleIdentifier] hasPrefix;@"com.google.sketchup"]){ return; }
    NSLog(@"ThawUp loaded as input manager");
	
	wasFront = FALSE;
	
	orig_glClear = APEPatchCreate(glClear, new_glClear);
	orig_glDrawBuffer = APEPatchCreate(glDrawBuffer, new_glDrawBuffer);
}

static void new_glClear(GLbitfield mask) {
    if (wasFront) {
		wasFront = FALSE;
		NSLog(@"ThawUp causing CGLFlushDrawable");
		CGLFlushDrawable(CGLGetCurrentContext());
	}
	orig_glClear(mask);
}

static void new_glDrawBuffer(GLenum mode) {
	if (mode == GL_FRONT) wasFront = TRUE;
	orig_glDrawBuffer(mode);
}
@end

Thanks for trying this with 10.5.2. For now, this patch is the best solution I've seen.

Hi .... I have recently bought a macbook with leopard (osx 10.5). I want to buy sketchup pro but thought that I would download a trial version to check it out. There are many hang problems which (compared to Sketchup 5 on my old pc) drive me nuts... Its seems that this is a problem experienced by other users and it also seems that there may be a solution... Can you help ? markodd

Are the hangs related to trying to rectangle select? If so, download the patch in the first post of this thread.

inio you are a Genius

I sometimes like to use my girlfriend's macbook at home (I normally use a MacPro at work) and found the hang time on SU was just unbearable.

Your fix has totally sorted it; amazing... how come Google don't sort this on a release, or even put your patch on the help site?

It is even making me wonder whether to save the cash on the difference between buying a MacBook Pro vs MacBook for my home machine...

Hi,

I'm on a MacBook Pro 2.4GHz with Mac OS X 10.5.2 and using SketchUp 6.4.120 (latest version, far as I know).
Both with and without the patch, I'm getting full system hangs periodically, usually when I pan or orbit. It's not completely debilitating, but it is of course kind of annoying...

If I leave the system when it hangs, it still seems to save out an Autosave file, but it's otherwise completely unresponsive. Does this sound like the same issue or something different?

(Also, with the patch installed, I would occasionally get a similar system hang in Adobe InDesign CS3 when switching palettes around...)

Thanks!

David

i'm also getting the hang... 10.5.2 w/all updates + SU 6.4.120

i notice it in two situations:

if there is an image imported. this causes a hang that requires a hard restart about every 15-20 min.
the beach ball hang... which i can't define with specific actions, but happens pretty frequently hanging for 10-60 seconds at a time.

anyone talk to google?

i just installed the thaw-up... thanks! i'll post my results...

antioche · 3 Apr 2008, 09:12

I've been looking for a way to sort that beachballing bonanza every time I selected something in Sketchup with a rectangular selection on my Mac Mini Dual-Core. This worked like a charm! The selection is now almost instant!

Thanks a lot for working out this great patch!

howdy · 14 May 2008, 06:01

didn't work for me. leopard still beach balling away. really too bad.

inio · 14 May 2008, 15:06

You may need to restart, or at lest log out, after installing it for it to take effect.

bigstick · 1 Jun 2008, 10:33

I too am getting OS X Leopard SU instability and lockups. Mainly due to using the pushpull tool - I think. The fact that people are still posting about this 5 months after you uploaded your fix, leads me to believe that the latest updates haven't fixed the issue. I'm going to try it and see if things improve, even though my issues don't seem to be the same.

Thanks for the time you have spent on this inio!

inio · 1 Jun 2008, 17:16

Yeah, I'm a little surprised this issue hasn't been fixed yet. Three OS updates (four if you count the "Graphics Update") and one SketchUp update later :/.

(BTW, confirmed to be needed with 10.5.3)

PeterPritchard · 26 Jun 2008, 12:11

hiya

currently using macbook pro running su pro 6 and 10.5.3

mine hangs when just rotating simple models

i assume your fix may help address this - is it a problem you've found

Edson · 21 Aug 2008, 10:31

i've read 10.5.4 fixed the problem.
