I haven't tried it yet. I simply found this discussion today and have been reading through the comments to see if my 2009 iMac model is compatible with the patch and Mojave. So again I'd like to ask, are there any late 2009 27" iMac owners who have gotten the Mojave Beta (with patcher) to work?
Thanks to dosdude1's Mojave Patcher your machine until the current Mojave beta version is almost totally supported except for a little bug in the App Store we were discussing about before.
