When running in a default white terminal, the text is grey on white. I can change the terrain via the profile for mactop, but would it be possible to change the text to be black so that it's easier to read on a default terminal?

BTW, great program - nice to see that info in a terminal when needed

I attempting to install mactop with brew on a M2 Max:

brew tap context-labs/mactop https://github.com/context-labs/mactop

brew install mactop

Problem

For what it does, this tool uses an insane amount of compute resources. mactop appears to have two threads, each using 50% of a CPU, so in total around 1 CPU constantly. Whereas similar tools, such as top uses between 5-10% of a single CPU. We're talking 10-20x worse in performance for an (arguably) similar tool.

I don't know what the source is of the high cpu usage, you'd need to profile or perhaps disable certain widgets in your dashboard one at a time to isolate and determine which one(s) it is coming from. Once isolated, doing some research into why/how it is so poorly performant and fixing it would be great!

I'm running mactop v0.1.8 on a M1 Pro MacBook Pro and the P-Core Usage bar randomly spikes and overflows to the right of the terminal and the displayed percentage is absurdly hight (above 2000 %) and does not match with any real workload spike on the system (the system is at rest). During those spikes other tools such as top, Activity Monitor or Mx Power Gadget all show a flat and low P-Core usage and frequency.

The function:

How about moving it into one of these (ref)?

• /Library/logs
• /var/log

Does not work properly with maxed out Macbook 16' m3 max (128GB)
E-cpu is constantly on 100%
P-cpui is on 0% and every second flickers to 50% than back to 0%

I noticed that mactop has quite a high CPU use. If I compare mactop and asitop at the same time and measure with Activity monitor, you can see this stark difference, the python process running asitop uses ~1.5% and mactop is using ~79%.

I worried it might be some issue with activity monitor, but htop shows the same differential (pid 12388 @0.7% vs pid 12342 @89%):

This isn't a contention issue, killing asitop and mactop still uses the same proportion of CPU.

It would be nice to replace Activity Monitor with this but what I like is its Memory Pressure graph:

Mactop always shows ~50% P and E, even when the machine is otherwise idle. Here is what mactop and activity monitor show at the same time, note the P cores seem to be idle in AM and 50% active in mactop, the E cores are more active in AM but still not 50%:

I've tried htop, gotop, zenith and some others and they all largely agree with AM, only mactop shows this 50% CPU use...

.

Latest 0.1.6, same on behaviour after brew upgrade mactop from 0.1.5 and after brew uninstall mactop && brew install mactop.
New powermetrics output is in the attached txt file

the text is barely legible with a regular black-on-white terminal, but it seems to work on the M1 Pro on my desk

At least brew update and brew install mactop are giving me a:

~ ❯ brew install mactop
Warning: No available formula with the name "mactop". Did you mean ctop, atop, mackup or mytop?

I saw this just now:

Updated 2 taps (homebrew/core and homebrew/cask).

brew install mactop is all I needed to get it downloaded. Congratulations on getting into Homebrew!
