MenuMeters works fine on my Mojave, but from reading release notes it would appear to run on BigSur as well. MenuMeters for OS X El Capitan 10.11 and later https://member.ipmu.jp/yuji.tachikawa/MenuMetersElCapitan/ and https://github.com/yujitach/MenuMeters

Wow, didn't know there was a new version — thanks! I recently booted up my 2008 iMac to get some old files, and I was reminded how much I liked MenuMeters.

Confirmation here: it works fine on Big Sur too.

Pluto requires macOS 11 (Big Sur). It doesn't work on 10.15 (Catalina).

It works, but honestly it needs a visual update because it looks very err... hacker-ish?

I've been extraordinarily happy with iStat Menus for showing a variety of system info in the menu bar.

I used the MenuMeters forks up until a few months ago when I purchased iStatMenus. Love it and well worth the money, especially since I can used the unified view (so my widgets don't get moved around arbitrarily by menu bar reorganization).

One thing I recently discovered is that macOS has no capacity to deal with overflow of the "menu bar widget" area.

I had rotated my 27" 5K displays to portrait mode, which I find better for coding. That made the menu bar narrower. The widgets in the menu bar on the left side just don't appear when the frontmost app's menu is too wide.

Since I use iStat Menus for this purpose, which puts (in my configuration) 6 different widgets there, and have several others as well, lots of icons were simply inaccessible.

That is one argument for Pluto's approach here.

Bartender app is great for that (and should have been sherlocked like 4 releases ago :))

Oh, great point! I forgot about that app, and indeed it would have saved the day.

(Ultimately, I decided I wanted at least one of my monitors landscape anyway... I realized this the first time I wanted to watch a video program, ha ha.)

I'm not certain I know what you mean, but have a look at https://bjango.com/mac/istatmenus/

Give it a try, we think its a lot nicer than the tiny menu bar stats most apps provide -- they just don't display the right amount of information.

You can quickly collapse it away when you want it out of the way by clicking on the left mode "PLUTO" label.

Thanks! I mostly want to see CPU and wifi activity, so a menubar widget covers most of my bases. I also don't have a big multi-screen setup, so I have a stronger preference for menubar widgets than some people.

You can display only your CPU & Wi-Fi in Pluto. It becomes quite compact then. The CPU view can be compacted further, too.
