No sound? -- Fixed

After the latest release I noticed I don't get sound for my notifications anymore. I have allowed them on the System preferences and Slack preferences. All of the other applications are able to play sound.
Edit: Updating my review; I found what the issue was: I don't know why but Slack was using as default sound input/output something that wasn't even connected, instead of the built-in stuff. Raising the rate, since support also got in touch!

Developer Response ,

We're sorry for the sound hassles. Please drop us a line at, we'll take a look under the hood.

Useful app; terrible implementation

Slack's underlying technology, Electron, is incredibly inefficient. It doesn't behave like a native app, stealing focus multiple times during its slow startup process. It always has multiple processes at the top of actvity monitor, using more of both CPU and memory than any other app. More than Safari. More than Photos.

Slack is now a company with money, startup excuses for cross platform rubbish have expired. Hire a competent programmer for a month to do this properly!

That said Slack is useful and that is the only reason we tolerate it. Slack became the most popular chat app only recently. Perhaps the next app to become the most popular just has to do the simple tasks Slack does while not wasting resources on the older computers most people have?

App and mulitple workspaces

If you try to switch workspaces, the app takes you to the browser to switch workspaces but then keeps you in the original workspace not the one you want to switch to. I recommend that you keep a busy Slack in the app and use the browser for all the others.... EDIT eventually creates a bar on the left and you can sign into each workspace. Does not always "take" so sign in a few times in the browser (restarting the app doesnt help).
