Leopard hang fix

inio · 24 Feb 2009, 00:40

Hello all,
I am about to buy a month old imac 24 2.8, but I am concerned with this slowness. I had the opportunity to try the pc, and install SKP (version 6) on it to feel how it went. It was all ok, apart from a certain slowness in orbiting. Well it wasn't really slow... the orbit movement wasn't exactly fluid, it came in steps, not in a unique animation.

I don't know what version of Leopard was on that machine (i forgot to ask, but I assume it is the latest), and I am wondering if this package will solve my problems or not.

Thank you for any answer on this!

As I said in the last post - this patch won't help general slowness. Just specific, unreasonable hangs AFTER particular actions (not during). In your case, it sounds like it was maybe using the software renderer instead of OpenGL.

that's strange, I had just installed the software on the computer :S

oh well, I'll ask to take a further look!

i must say the hang problem is not restricted to the card mentioned by barry a couple of posts before. my macbook pro has a geforce8600 and i have the same problem with the latest SU7 build (10035). i will revert to the original build (8656) to see if the patch will work.

Short answer: If you have Intel GMA950 graphics (early MacBooks and all Mac Minis?) and SketchUp is locking up after you box-select or just randomly after you try to select objects, this download my resolve the issue. The latest versions of MacOS and SketchUp that this patch has been confirmed useful with are 10.5.6 and 7.0.8656.

does it work for the latest build (10035)? is it restricted to Intel GMA950 graphics? it seems that the same problem afflicts other macs running 10.5.6 as well.

There should't be anything build-specific about the patch. It just causes a certain OpenGL call (glClear) to make an extra call (CGLFlushDrawable) when it's called after drawing to the front buffer. As long as SketchUp follows the same call pattern, it should continue working.

It's possible that this bug exists in other drivers. I'll test on a current-gen MacBook tonight if I remember. Other than that I don't have any other Intel macs available.

thanks. for what it is worth, i own an intel macbook pro 2.4ghz and its graphic card is the geforce 8600M GT.

Make sure you're not affected by http://support.apple.com/kb/TS2377.
We also look at http://developer.apple.com/graphicsimaging/opengl/capabilities/ but you should be OK with that list.
Send me the model, steps to test, and time, and I'll write an automation script to repeat it and time it with multiple tries.
Look at Mitchel's 3D Basecamp presentation on working with large models: http://www.youtube.com/watch?v=hnhkei2dSrY if it's not hardware related.

Hope that helps.

My Macbook Pro T9300 2.5Ghz,4GB RAM, VGA 8600M GT,Leopard 10.5.7 run SU 6 & 7 very slow,in rotate,move,....(working on a large model).I try Thawup,maybe it not work, I don't see different.
In Window,SU run smooth!! Maybe VGA driver support for MAC not good!
Any ideas ???

Chris Fullmer · 23 May 2009, 14:27

Hi Lehieu, you can try updating your Mac video card drivers directly from the video card makers website. Also, there's no need to write in bold like that. We can all read it even easier if its plain type. Thanks

Chris

chris,

there is no update for mac drivers at the makers' site. it seems that only PC drivers can be updated.

jeff hammond · 23 May 2009, 20:00

right. nvidia, for instance, doesn't develop OS X drivers and they are provided by apple. The driver updates are included with the normal software updates.

It's probably just a case of a big SU model acting sluggish and lehieu didn't actually say the same exact model is smooth with windows but not on his mac..
i'd be interested in knowing how large the model is (model info->stats)

there is also the issue of model organisation. if he does not use layers and scenes to organise the model and its visualisation no graphics card will be able to handle it.

thank you....worked like a charm

I was reinstall MAC OS 10.5.6 (come back from 10.5.7) and install SU7,SU6,ThawUp (Thawup is only install in SU6 folder).Sketchup on MAC OSX still working slow (in rotate,view...action,fps is down). In Win,it's faster,smooth (on large model). I don't know the problem ?? Who can help me??

Just installed it. You total star! I've lived with is bug so long I've got used to it.

I'm usually just grateful if SketchUp doesn't crash. It's a great program but massively unstable on Mac OS which is a huge shame.

Your patch has speeded up performance on big files amazingly too.

Sketch Up still hanging after install on OSX 10.5.7. Thaw Up seems to work for me and sometimes not. It's extremely frustrating when I am trying to do a project. I've done the Leopard graphics update at 10.5.2 and installed Thaw Up shortly after. The problem really hasn't seemed to go away all up to now. Any ideas?

Also I have a partition of an early Snow Leopard developer edition (Build 10a222). It still seems persistent in there as well.

I have this same issue on my Macbook. My setup is: GMA x3100 video card v10.5.7

I am working on a very basic sketchup model, I get a long lag time when I selected an area with the rectangle tool. I tried the Thawupinstallerbut it did not seem to help. Anyone know anything else that could be the root of this problem? Since I'm using SU7 will this not work for it? Thanks.

I'm experiencing hangs as well; the usually occur when trying to select a line. The hangs take about 10 seconds. They occur only when "Hardware acceleration" is ticked in Preferences. Installing the ThawUp patch did not help.

hi&thanks for this great patch!

i got pretty frustrated to see that my old p4 pc running sketchup on winxp easily outperforms my macbook due to the mentioned freezes...
disabling fast feedback only did not help. if i disable hw acceleration, the freezes vanish. but of course you get visibly better performance using the patch. (btw, rotating large structures without hw accel on the mac looks about as "smooth" as with hw accel on the mentioned pc with geforce fx 5200 go)

i wonder if 10.6 works any better - according to http://developer.apple.com/graphicsimaging/opengl/capabilities/ opengl implementetion has been worked on since 10.5.8 (version 2.0 for gma x3100 and 1.4 for gma 950 instead of 1.2 for both in leopard).
