I've seen anecdotal evidence that macOS Catalina is slow to launch apps, but it also seems to be slow to switch between already-running apps? cmd-tabbing between different apps on a 2018 MacBook Pro sometimes takes a few seconds to show a winodw. https://sigpipe.macromates.com/2020/macos-catalina-slow-by-design/
[Notice Regarding the Transfer of the mstdn.jp / mastodon.cloud Services] We have received several inquiries showing interest in a transfer following the announcement of the end of the mstdn.jp and mastodon.cloud services. As a result of subsequently evaluating the situation and making preparations, we have decided that the corresponding services will be transferred to Sujitech, LLC. on June 30. Thank you.
