Catalina - Annoying Update

Final comment (maybe)

You were given the choice of upgrading or not.

You were strongly recommended to take backups.

You had the opportunity to research this forum and also the wider web to see what possible problems your mac might experience.

If you use it for work you could have taken a non-work day to test out Catalina and within  hours work out if it was for you or not. i.e. keep or revert.

Apple make it easy for you to revert to the original OS, even publishing simple instructions and a free Time Machine program, the best backup app on the market.

I did all the above researching and testing, and apart from a problem with an old version of an app it went smoothly. IMO the fastest MacOS ever. 

I already got rid of 32bit apps last year.

 If you just pushed the “Install” button to get the latest Thing with no research, no preparation, no test plan and no backout plan then you will have to accept the result.

I guess you missed this part…

If the installer shows a list of apps that are not optimized for your Mac, learn about 32-bit app compatibility, then choose whether to proceed with the installation.

Yes I forgot

Because it is a 32 bit installer

You were warned in Mojave
