Hello. I have Sketchup Make 2017 on my iMac that is running OSX 10.11.6. I do my drafting work on this machine because of the big screen. However, when visiting clients, I copy the .skp files into my flash drive and show it to clients on my Macbook Air laptop which is running OSX 10.9.5
While I had the earlier version of Sketchup, I was able to transfer and open .skp files between my desktop and my Macbook Air. But now, after upgrading to Sketchup Make 2017 on my desktop, I cannot open any of the new .skp files transferred there.
My problem: I cannot upgrade my laptop to OSX 10.11 as I never downloaded the upgrades since 10.9.5 and now the only option is to upgrade to OSX 10.12 (Sierra). However, from the Sketchup site, I see that Sketchup make will not run on Sierra.
What can I do to get back to the previous state where files could be transferred and opened between my two machines?
I’m changing the title of this topic, as it actually has to do with transfer between computers running different SketchUp versions, not with OS X versions. As Dave noted, the answer is to downsave to the oldest version.
