I have a Macbook (2.16 GHz, 2 GB RAM) which I recently updated with
Leopard. I am new to Sketchup, but I noticed that there were
performance problems. A couple of weeks ago I downloaded the version
that presumably solved the issues with Leopard, but I am still seeing
problems.
Performance is poor and choppy. The more things I add to the drawing,
the slower it goes, and the less responsive controls are. I may move
some item, release the button, and move the mouse to perform the next
operation, and the item is still moving. Sometimes you select the
push-pull tool, and nothing happens.
