Apparently it's bad enough to wait a few months.
How about Adobe Photoshop Elements 11 and 14?
Glad some folks have Catalina working.
I see more than enough gripes to hold off 'til at least Christmas.
I agree with previous comment that Apple has seriously deteriorated in QC. Upgrades should work for everyone-always-right away.
With 43 years in IT, I've been using Macs since the Little Mac in '84 and have watched the degradation sadly. Upgrades worked fine until Cook, Beats and Co. replaced Jobs and became a telephone company with no interest in the "next new thing".
There haven't been any. Apple is now a utility like Microsoft. Competing with Samsung for iterative phone upgrades. They still make great hardware and software-after they get the software working right in a year or so.
Mojave is stable enough and iTunes is quite satisfactory to maintain my 15,000 and growing, track music library on my iMac, external on and off line hard drives and DVDs, Classics, iPads, and 7th generation Touch. Catalina will probably be the last OS my early 2013 27" iMac will run anyway.
At 88, I'm quite comfortable with the fantastic capabilities of all my Apple products. I remember the wonder of my first HP digital calculator about 40 years ago. I think the need for instant upgrade to Catalina is vastly exaggerated. My house is full of Apple products and Alexa devices that they already talk to.
Sometimes it pays to be able to say "Enough". If it ain't broke, don't fix it, and Mojave ain't broke.
Sounds like Catalina is, if only slightly.
The beta process is still underway.
