System Monitor Version History
Release 1.3 (Build 130506)
- Added new feature to list Macintosh volume names as comment lines in the menu for monitored disks. This helps users to more easily identify which volumes are located on which disks.
- Added new preference setting to display paging operations as transferred memory sizes, instead of as counters.
- Bar chart displays shown in the menu bar have been slightly redesigned to provide a more elegant look.
- In the list of possible providers for WAN IP address lookups, the service of “The Privacy Ecosystem” has been replaced by the service of Amazon Inc.
- Corrected a problem where the activity indicators of network interfaces did not work correctly when all activity indicators for disk drives had been disabled.
- Corrected a problem where the first digit of numerical displays of temperature readings in centigrades or of total system load may have been suppressed by the menu bar layout when a value of 99 was exceeded.
Release 1.21 (Build 120402)
This is a maintenance update which enhances network monitoring behavior on systems where complex changes regarding network environment or network hardware occur at runtime.
Release 1.2 (Build 120210)
- Added new monitor item to display the main temperature at the first processor and all fan revs.
- Added support for new features of Mac OS X 10.7 Lion.
- Added new feature to optionally display the top 5 memory consuming processes with absolute real private memory readings instead of percentage values.
- Added new feature to display the bandwidths of network interfaces as bits instead of bytes.
- Added new feature to optionally suppress decimal places for large numeric displays in the menu bar.
- Added new feature to control the widths of graphs displayed in the menu bar.
- Added new feature to change the order of the different menu bar items.
- Added new feature to take over preference settings from a possibly installed trial version of System Monitor.
- Enhanced the layout of two-line menu bar displays.
- Readings per second are now displayed with a cleaner layout.
- Corrected a problem where peak values for disk throughput and accumulated data transfer readings for network interfaces could be displayed incorrectly under certain circumstances.
- Mac OS X 10.6.6 and 10.6.7 are no longer supported. The minimum requirement for usage is Mac OS X 10.6.8 or later.
Release 1.1 (Build 110411)
- The space needed for numerical elements in the menu bar will no longer be optimized on each refresh. This avoids any distracting “width flicker” when the menu bar has been configured for numeric displays.
- Alternative to the display of total CPU load, the individual loads for each single CPU can now also be displayed in the menu bar.
- When displaying network activity, new alternative icons more reflecting the meaning “upload / download” can be selected.
- Two-line displays for numeric data in the menu bar use a larger font size now.
Release 1.0 (Build 110228)
First official version of System Monitor.
