Fixed, finally found it. Selected all photos in Aperture and Relocated Originals. I will then import into LR.
Some people are using Adobe's plugin for that.
I think there was also a 3rd party plugin - dunno which is better.
Some folks have had problems with Adobe's but dunno how many haven't..
I suspect an internet search would allow you to find it expediently.
You're welcome, but did you find the plugin(s)? did you look?
There is also a help doc for doing manually, if you prefer, e.g.:
So, what's the plan??
No, what I ended up doing was selecting all photos in Aperture followed by selecting "Relocate Originals". All the originals were then placed in a folder of choice, which I then imported into LR.
If you can get it to work, most folks should use the Adobe Plugin. Although the manual method is good, especially if you tag data beforehand, you have the ability to transfer more information, more automatically, with the plugin. For example, stacks can be transferred. Adobe says Faces should work, but that piece still has bugs.
Most importantly, the plugin will allow you to copy both masters and previews (at the ore-specified, generated resolution). The manual method makes combining these difficult two, especially stacking the two.
