iMac can’t open any applications after updating to Catalina

Question

iMac can’t open any applications after updating to Catalina

i have a late 2013 iMac and whenever i try to open google chrome or a game application, it just bounces for a while and then says it’s not responding. i can open safari, but i can’t use the online game i play that uses flash.

i had yosemite before updating, and then i got catalina. it was working fine on yosemite; but i updated because i wanted to use final cut pro. i tried undownloading final cut pro because i thought it might be a part of the problem, but it didn’t help.

how can i fix this or figure out what’s wrong, why can’t i open applications?

i tried shutting it down, unplugging it, and waiting for a while. i also tried shutting it down and when i turn it on pressing d, but it said no issues. i’m not very tech-savvy, but i’ll try any advice

Sorry, but old 32bit applications no longer work in macOS Catalina.

see > 32-bit app compatibility with macOS High Sierra 10.13.4 and later - Apple Support

FWIW, that doesn't work so well in Catalina. There is no longer a 32/64bit column so you would have to click on every app to check.

I found the site but I can't test it without an account which I'm not willing to create. Sorry.

That can't be the case seeing you have Google Chrome installed. That doesn't come with a Mac.

Ack' my bad, thanks for the heads up. I haven't fully made the transition to Catalina and only occasionally run it on an external SSD.

Just curious, which online game? Safari is the last Mac browser that still supports Flash.

in the software tab, it just says “no information found”. i don’t think i can download a software to do that either because i can’t open any application that didn’t come with a mac
