I made the leap to upgrade to Catalina in early December. However, I wish I waited!
- I love the updates to the Photos app. However, I had to update my old Aperture library. The good of that is that the Photos app seems much better than Aperture which had not updated in many years.
- Overall, the upgrade seemed easy. Then again, I had plenty of extra space on the 2TB boot drive of my 2019 MBP.
