System Monitor

2.6
16 October 2019

Activity monitor from the maker of TinkerTool.

Overview

System Monitor is an application for the menu bar of OS X, designed to inform you unobtrusively about the activity of your computer. You can retrieve up-to-date technical data any time, like process load, main memory consumption, storage space, disk activity, communication on network interfaces, etc. By positioning the app in the menu bar, minimum screen real estate is wasted. The program monitors your system continuously and is readily available when you need it.

If desired, System Monitor can also simulate the flickering activity lights of hard drives or network sockets in the menu bar. This is possible either in color or, perfectly integrated into the design of OS X, in inconspicuous black-and-white. PC switchers who miss this feature on Mac computers can easily retrofit this function with System Monitor.

What's new in System Monitor

Version 2.6:
  • This version adds full support for macOS 10.15 Catalina.
  • Legacy technology has been removed from the App. The minimum required OS version is now 10.11.
  • As side effect of adding support for Catalina, System Monitor now strictly follows the guideline not to monitor hidden storage volumes. This avoids confusion with the swap space volume, local Time Machine snapshots, App Translocation volumes, or the data part of the Catalina system volume. When choosing volumes for monitoring free storage space, the App uses enhanced user guidance to present the relationship between physical disks, APFS containers, APFS volume groups, and APFS volumes.

Been using this app since 2014, it's pretty stable and always delivers its promises. It would be cool to be able to see which 5 apps are using the network bandwidth though.

Oh damn, why did it take so long for the update? Now I've already bought iStatMenus. But if System Monitor is only half as good & stable as Tinker Tool System and Tinker Tool, both of which I highly recommend, then this app will be worth a lot more than $4.99. :)

I also gave it a spin however it is menu bar hog with all the statistics it puts up. Now that i see all the info in my menu bar what do i do about it and so what? It seems to me that i can get the same info by launching activity monitor which eats up no menu bar space. If i were to spend the 5 bucks to buy this app i would like to see some icon for this System Monitor in the menu bar with a drop down menu to select the processes that this application is monitoring. However, my basic question is, so what ? I have used Macs for more then twenty years and never worried about all those processes that System Monitor monitors. If my Mac burns up so what just use apple care to replace it. So right now I am going to use app delete to trash this programme unless it has a built in uninstaller.

I gave it a spin. It's quite complete, though I haven't enough room in my menu bar for all the items it monitors. The biggest problem I have with it, though, is the Lion/Mountain Lion style grayscale interface. That is to say, it's double ugly. That's a deal breaker for me. Until they have decent color options, I won't even consider buying it. I use a hack to restore color and custom icons to the Finder window sidebar in Lion. And I currently use MenuMeters to monitor system functions in the menu bar. It uses color and takes up relatively little room in the menu bar compared to System Monitor. Color enhances usability. Just because Apple decided to ignore this basic fact is no excuse for developers to do the same.

Its not bad but I still prefer iStat Menus. System Monitor uses about 0.5% up to 10% when idling. iStat Menus only about 0.5%. If the dev can fix the high cpu usage I would certainly take another look at it. ATM .. promising but not good enough.

This app seems promising alternative to iStat Menus. I would like to see:      • an option to configure the font sizes      • an option to view the fan exhaust on the menubar      • an option view the infos on the right side of the menubar Please add these to the update list! Looking forward to future releases.

Just purchase this app from App Store. First four stars for its lower CPU consuming (less than 0.5% most of time) than other simliar apps. It has a concise drop-down menu for us to read. One point for this. But I have to say that its Preference Setting Interface is awfully ugly... Another important feature seems missing in this version… It looks like the app couldn't detect the Fan speed, Temperature, and the Battery Life.

Update: The Developer responses so quickly. Now the new version of System Monitor can show temperature and fan speed now. Thanks.

@developer: Could we have a little deeper understanding as to what the advantages of this over iStat Menus may be?

Looks like it is similar to iStat Menus and MenuMeters. But it only costs 1/3 the price of iStat Menus. iStat Menus = $16.00 System Monitor = $4.99 MenuMeters = FREE The only question I have is which one is more stable and doesn't have a memory leak. iStat Menus has been fantastic - with a modern interface. MenuMeters is FREE can can't be beat for the price, though it has a more primitive interface. I would chose whatever has the interface one is most comfortable with. I already have iStat Menus so I probably won't be purchasing this version - though the price is great.

Agreed @Psychiatry, I've used MenuMeters for years and it did a great job, but graduated to iStat Menus and it has been fantastic. I don't see a need to switch, but am open to a superior option, particularly if it has a smaller memory and cpu footprint for the same functionality.

In most cases and in this case, if you go to the developer's site you can get a trial download.

I'm quite certain that wasn't there yesterday when I first saw this app posted here. The developer's site does show that the trial was posted today, so it had to have been since then. Thanks for bringing it up.
