Atom won't open on Mac

Hi. I have a fully updated MacBook that I am the administration on and am trying to download Atom. Everytime I have tried to download it and run it, no window pops up but my computer says it is open. I have allowed it to be downloaded from the internet. Please help if you can! :slight_smile:

I am having the same problem. My Atom was working about 30 minutes ago, then I just updated my MacOS, then it stopped working. There must be a compatibility issue with the new MacOS Update. Hopefully they will fix it soon.

Having a similar issue here. Last night I updated to MacOS Big Sur from a MacBook Pro medium-high tier acquired 2 weeks ago, and today my Atom is extremely slow. Taking up to 5 seconds each time I click inside the code to somewhere else, same for typingโ€ฆ Even the settings are extremely slow when opened, took more than 2 minutes to fully show up all the packages that I have installed.

Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.

I finally found a way to open atom editor on updated Mac. Using a installer instead of the atom.io download site.

this one worked for me.
