Leopard hang fix

[heckler]

Thank you so much Inio!
Your fix was too helpful!

Inio, your fix is also useful in sketchup's update dating 5th of december.
It really speeds up sketchup on the Mac Book, great work!

[GaryWith1R]

Thanks Inio - Sketchup was unusable even after the latest update with constant hangs. I've been searching for a cheap alternative to complete a project I'm in the middle of, but couldn't find anything as powerful - so this fix has saved the day!

Good to know. The fix should be pretty harmless - in the worst case it will cause graphical artifacts and a very slight slowdown in future versions once they fix the problem directly.

edit: that said, it should be uninstalled once the problem is fixed. There's no reason to keep it around and it could conceivably cause minor problems. This is why I included the uninstaller script.

Thanks.. that fixes my problems.. I thought it was because I had installed earlier a patch for the pro... Cheers

Worked for me as well! Thanks for taking matters into your own hands!

just got SU6 installed on my new macbook and is really disappointed at the problems I'm facing on getting it to function 'normally'. I've been using Sketchup since the first versions and is very impressed with how its grown. However, that was when I was still on Windows. Incredibly, SU6 works so much faster on my 2 year old Dell XPS (centrino duo).
Been searching around the whole day today and turns out that its got something to do with the macbooks GMA 900 video card that's now working with OpenGL and sketchup which caused those little dots to follow the cursor. Turning OpenGL of, solves it but also slows it down so much that its not exactly functional or usable.
I'm still on Tiger and on a 2.16ghz macbook 1Gb RAM and the older video processor GMA 900.
Should I try this install?

Trying it now. SketchUp has sucked for me all around since the upgrade to Leopard.

Edit: The fix seems to work perfect. Very appreciated!

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

[kiddo]

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,

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

Inio,

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.

[JasonWD]

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
