I use Thunderbird on a MacBook Air (Apple Silicon). Just be warned that it seems to use a lot of CPU resources (when seemingly not doing anything) and therefore uses up the battery faster than it should. It's not a deal breaker. I tend to keep it closed until I check my mail, which isn't ideal, but then again, it's not the worst productivity/stay focused habit to have. This is as of May 2023 and earlier. Hoping the update/integration with Firefox may improve this.

High cpu usage has been the case with Thunderbird on MacOS since forever. I've long wanted to switch to apple mail due to battery drain, but I just can't work with a unified accounts. I have multiple accounts and like keeping them separate.
