If this has been posted elsewhere, please link me. I have tried 3 times to install Mojave on my Mac mini Late 2012. It technically installs but it's unusable. It's so ridiculously slow. Lag times are 30 seconds + for clicking on anything. And the wifi doesn't work. When I click on the wifi icon at the top, it says "no wifi card found." I tried when Mojave just came out. I tried again after a couple 10.14.x updates and had the same issues. I see it's up to .5 now and just curious if any one has had similar issues or has any ideas on how to get a good install. Thank you!
