這邊講的替代方案不是換掉 Teams，而是找其他的方法連上 Teams 伺服器，畢竟用 Teams 的人大多都沒得選...

在「Teams is killing my Mac every day (microsoft.com)」這邊看到的一些資料可以嘗試，裡面有很多抱怨 Teams 的問題，但還是有些人有給出一些 workaround。

大家主要遇到的問題除了 CPU 吃很兇以外，另外就是記憶體這塊。

一種方法是是用 Edge 瀏覽器的 extension 來跑，我本來想看看 Linux 上的 Brave 能不能裝，但沒有看到對應的安裝連結，大概是 Edge 限定：

If you don't want to use the Microsoft Teams app (which uses a lot of resources), you can:

1. Install the Microsoft Edge Web browser on your Mac

2. Log into https://teams.microsoft.com

3. Click ... > Apps > Install this site as an app

This will create an Edge app for Teams that uses almost no resources but has feature parity with the regular Microsoft Teams app.

We tell all of our students to do this, and it has solved all Microsoft Teams performance issues on student Macs (both Intel and Apple Silicon).

另外有人提到其實官方是有放 M1 的 preview 版本的，雖然不是正式版，但總是比 Intel 版本會好一些：

If you're running an Apple Silicon Mac you can get an early build of Teams osx-arm64 from the exploration build link listed here.[0]

I've been running a daily build for a few weeks and it's noticeably better than the Intel build on an M1 Pro. It launches in half the time and feels far more responsive (probably due to not needing to use the Rosetta JIT for Electron). That said it's still a daily "exploration" build so YMMV.

據說會少吃一點點記憶體，就真的大概一點點：

Can confirm it is snappier on a M1 Macbook Pro and using *less* RAM, maybe about 10% less.

但據說這個 preview 版本在自我更新時會跳到 Intel 版本，還要再找一下 workaround 關掉自動更新：

How do you prevent it from automatically updating to the Intel version? I keep downloading the preview builds and they keep getting updated.

後面還有看到有人說他直接實體隔離，把這些肥滋滋的 app 跑在另外一台 Mac 上，然後透過 Universal Control 使用，大多數的情況下都夠用，真的有需要分享畫面時再跑在自己機器上，用完就可以關掉：

Thanks for the tip. I'll give this a try!

For work, I have to run Microsoft Teams, Slack, and Discord. Of those 3, Slack surprisingly uses the least amount of memory (~700 MB), and Teams uses the most (~1.5 GB). I dusted off an old Intel Mac (literally) and interact with it using Universal Control. It only runs those 3 chat apps + mail. It's turned out to be a great way to offload resource hogs and as an added benefit, it minimizes distractions. I'll occasionally glance at the dock to see if there are any notification badges, whereas on my main Mac, I'd feel compelled to deal with notifications immediately.

When I have to share my screen or focus on a conversation, I'll fire up one of those 3 apps on my main (M1) Mac and quit it when I'm done.

Universal Control still feels rough around the edges, but it has saved me from ditching my Macbook Air and shelling out for an M1 Macbook Pro. Sometimes there are issues with reconnecting to the Intel Mac, but it seems to resolve itself if I wait a bit or turn off/on wifi.

大家都在找方法 XDDD
