I was forced to upgrade to catalina the other day, and so far most everything seems to be ok… EXCEPT I have 5 apps on my dock that have lost their icon and reverted to the default icon. 3 of these are commercial apps (including Xojo) the other two are apps I wrote.
funny how things happen, I just in the last 2 days moved from 10.13 to Catalina, while there are quite a few things I do not like, including how slow it seems, the icons misbehaving is not one of them yet.
but if it does happen I will now know its not my fault.
my system ‘upgrade’ was due to getting an SSD in the iMac so the install was completely fresh as opposed to updating the original OS, in case that might make a difference.
Yes it does. I had a really bad experience with a 16" MacBook Pro earlier this year and Apple attributed most of the issues were down to the Migration Assistant that Apple Care knows is broken. Apple’s own advice was to do a clean install and manually move my data, re-install my apps and so on.
Which I did and for the most part it’s more reliable than the first time, but yeah there’s a ton of stuff that just stops working.
Then I’d recommend Googling how to reset Launch Services. I could have recommend “Preview Reset”, but that was a 32-Bit app and so won’t work on Catalina or newer.
I hope this help with Catalina (no, I do not run it, yet).
I get good side effects, but my custom document does not have its custom icon (but funilly, if I changed the extension to json, it get my json custom document… )
