Thanks Dave. I figured it out. I was trying to Export rather than Save As. Bonehead move.

It used to be easy, but I can't find a way to save a 2019 file back to the 2018 version.

I have no idea what happened, but everything was working fine on the MBP. I now believe something was wrong with the file.

However, I returned the MBP and got a 21.5" iMac. 2.7 GHz, i5 quad with the 6770, 512 MB GPU. Wow, what a machine! I haven't had a desktop in decades and this is real treat for me. SU is blisteringly fast on this thing.

Cheers!

This is strange. I have been using a MBP for some time, however its running an nV grahpics card. I also tested an iMac last week using an ATI card and it worded well.

Just a stab in the dark! Would it be worth checking to see if your system needs some GC driver updates?

Mike, do you remember what kind of ATI card the iMac had...or it's speed? I'm seriously thinking of upgrading my MBP to the next higher unit; one with a 1 GB card. It's not cheap ($400 more) but I may just go ahead.

My apparent lack of a Materials library is due to my inexperience with the interface. I get it now.

I'll check for GPU driver updates, but I think I'm good there. I haven't been here for years, so I appreciate knowing you guys are every bit as helpful as you've always been. What a great resource you are!

The latest SUp v8M2 had some tweaks to make it compatible with OS Lion...
Are you using this version?

Where would I find SU v8M2? In another thread, I gleaned that one should activate "Install Extension.." from the Preferences>Extension window, which I had already done. Is this what you're talking about?

@dave r said:

Out of curiosity, have any of you experimented with the OpenGL settings in Preferences?

I have disabled and re-enabled Hardware Acceleration as well as Fast Feedback and don't sense any difference. I'm running 8.11751. It's just sluggish and not crisp like my old XP machine with Nvidea.

Edit: Sorry..disabling Hardware Acceleration has the expected effect of eliminating anti alias-ness, which is unacceptable.

Hi Driven and TIG,

Driven...I have since loaded on some basic plugins, but initially, the only plugins I was running were the native ones.

TIG...I'll download the update and report back.

The problems I'm having are: I have a small 6mb model that continues to rotate after I'm done and generally slow navigation. I should change my profile to show my new system which is 15" MacBook Pro, 2.2 GHz, i7 chip with AMD Radeon 512 MB HD 6750M GPU. I wonder if I should return this think for a better GPU..

Thanks for the quick reply...Ron

Edit..I can't access Materials. I see the folder under Google Sketchup 8, but it won't open while I'm in SU. I think an uninstall in is order here. This may be the solution.

I'd sure like to get an understanding of this as well. I purchased a MacBook Pro with Lion a week ago and SU is unworkable. I'm getting used to the Mac interface, but may have to go back to Windows unless there is some kind of work around.
