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?
