- Added support for detecting network interfaces of type "WiFi-Aware Neighbor Awareness Networking" in macOS 27. - This version returns to machine-based license checks, avoiding issues with specific configurations. It is now possible again to use the app without a permanent App Store log-in.

- Added new setting to allow the use of warning colors for the main temperature display in the menu bar when the system encounters elevated readings. - This version tries to avoid a rare crash situation that could occur when there are several rapid network configuration changes while the app is starting up. - Minor internal improvements and modernizations.

- Added support to correctly identify the new super cores when monitoring processor load on Macintosh models with M5 Pro and M5 Max processors. - Several small additions to the reference manual.

- The line widths used by the graphical elements of monitor items in the menu bar have been unified and carefully reduced. History graphs now use slightly rounded corners. Some designs were still optimized for the previous Lucida Grande typeface of macOS and have been revised. - Unmonitored hard disks and network interfaces are now automatically sorted in the settings tables for easier handling. - Added a workaround for an operating system failure where a monitor item in the menu bar may not always shrink to the correct width when removing sub-items. - The VoiceOver support was enhanced for some elements in the preferences window. - The Release Notes have been revised for up-to-date versions of macOS.

The user interface and processing in cases where the App Store requests a revalidation of the license have changed. The program now quits during the procedure, preventing the possible optical illusion that the app would be part of license checks or the handling of Apple Accounts. These tasks are carried out exclusively by macOS. Users have to restart the app manually when the App Store prevented a successful launch.

- Integrity and license checks have been modernized to remain compatible with the latest versions of macOS. For this reason, support for macOS 11 and 12 had to be removed. The minimum required operating system version is now 13.5. - Modernized organization of language support files. - The reference manual adds information about temperature sensor selection on Macs with M4 processors. (For installations together with System Monitor Plus.)

- Added new layout option for the menu bar to suppress labels in small two-line display items. This can further reduce the necessary widths on small screens. - Added workaround for an issue of macOS 14 Sonoma where the operating system could prevent that the current status of individual IPv6 addresses is shown as help tags (tool tips). - The preference pane to control layout settings for menu-bar items was redesigned. - Better help tags for the available menu-bar items of the processor load section. - Fixed a problem where a misleading "less than or equal" symbol could be shown for the temperature readings of inactive CPU cores of M3 Pro or M3 Max processors when they entered a special power-saving mode.

- Added new feature for modern Macs with Apple Silicon to monitor whether the Apple Neural Engine is currently in use. This is a new, separate monitoring item. It is not available for Macs with Intel processors. - Added new option to ensure that history graphs for processor load won't auto-zoom, even if the system is never put under high load. This way the scale of history graphs is guaranteed to match the scale of the bar indicator. - Modernized organization of language support files.

- This version adds preliminary support for future versions of macOS. - Added new feature to detect situations where the system is an overload status in which additional load created by acquiring process statistics should be avoided. The "top 5" process monitoring functions will now automatically pause for one or two minutes when such a situation arises. System Monitor Plus 1.8 or later is required for this feature to take effect.

This is a maintenance update which fixes an issue with the list of volumes that can be configured for monitoring. On very specific circumstances, depending on the individual upgrade path of the App and of the operating system, the system volume could disappear and temporary APFS backup snapshots could mistakenly appear in the list. It may be necessary for some users to re-add missing volumes to their monitoring preferences.

- Virtual APFS snapshot volumes are no longer offered for continuous monitoring in the Storage Volumes settings. - Fixes a problem where storage volumes have not been monitored automatically before confirming the "menu only" settings when updating from version 5.6 or lower. - A cryptographic security feature was removed to ensure the App can be imported to France again.

- Added new feature to choose which of the disk volumes that are selected for monitoring should be included in the total sum shown in the menu bar. - Added new feature to select between predefined colors to show secondary items in the menu bar, e.g. the load of efficiency CPU cores or the second value in two-value graphs. - The layout of the configuration window was optimized. It now has a larger minimum height. - Disk volumes and APFS snapshots that are assumed to be temporarily connected to the computer only are now immediately removed from the configuration table for storage monitoring instead of marking them offline. - More network interfaces for which macOS does not provide meaningful designations are now presented with readable names. - The strategy to search for copies of System Monitor Plus has been optimized.

This is a maintenance update which fixes a problem where the storage size readings of the main volume could not be monitored. From the previous version: - The automatic switching between normal operation of the user interface with windows and reduced operation in the menu bar will now work more consistently if multiple windows or special auxiliary windows are open. - For specific Mac model series with Apple Silicon, an additional reading for total internal electric power can be added to the list of sensors. This feature requires the free add-on System Monitor Plus version 1.3 or later. - Sensor access will no longer be generally rejected for Mac model series released in 2022. - The code base was modernized to prepare for future operating system versions.

- The layout of the System Monitor Plus preference pane was optimized. - Better user guidance in cases where access to temperature sensors is deactivated via preferences. - Enhanced behavior in cases where the network configuration changes while launching the App.

- Added new layout feature to automatically reconfigure the selection of display elements for each monitor item to a recommended setting for width-limited screens. This can be helpful for Macs with small display or camera notch. - Added support for expected changes in upcoming versions of macOS. - The policy for the selection of GPUs to monitor has changed. The program no longer suppresses readings for GPUs that are inactive during application launch. This will make monitoring of GPUs that are dynamically switched off for energy saving more consistent. However, this will also enable the display of GPUs that are inactive by default, e.g. the CPU-integrated GPU of Intel-based iMacs with discrete GPU. - Memory readings for GPUs whose drivers provide incorrect data are now filtered out. - System Monitor can now check for available updates of the System Monitor Plus add-on application. - Internal diagnostic features have been added. - Security certificates have been updated.

- Added support for processor type detection on the new M1 Pro and M1 Max systems. - Added more guidance for users who like to enable the display of absolute temperature values and fan revolutions. - Added guidance regarding possible restrictions on Macs with camera notch.

- Added new feature to processor monitoring which will now clearly differentiate between different processor types at the related overviews if available. For Intel processors with Hyper-Threading feature, physical and logical cores are indicated. For Macs with Apple chips, performance and efficiency cores are shown. - Added new option for individual processor load indicators in the menu bar. If the different processor types mentioned in the previous item are present, they can be shown with different shades of gray. - Adds protection against a problem where maintenance jobs executed by macOS in sleep mode could silently block the data link between System Monitor and the optional System Monitor Plus.

- Adds a new temperature indicator for the general thermal system status managed by macOS. - Adds full sandbox support for enhanced security. - Adds new indicators for specific temperature sensors of Apple Silicon Macs which are not always active and have a measuring range with a minimum value that cannot be fallen below. - Features to monitor load and memory data of other processes, as well as all hardware sensor support have been removed because they are no longer permitted in the App Store. All affected functions can be reinstated in System Monitor by downloading a separate add-on software. This download is available for free and anonymously. Separating these items in a second application makes sure that we gain permission to add new features to System Monitor in the future. - Adds a workaround for a defect in some operating system versions, where the system provides only 32 bit network statistics although 64 bit have been requested. The number of transferred bytes no longer wraps around to zero when the readings exceed 4 GiB.

- Added preliminary support for future versions of macOS. - The position of the information window when switching between application modes has been optimized to better support small screens. - Adds a workaround for failures of legacy drivers for third-party network interfaces that could prevent them to be usable for the network activity indicators in System Monitor. - Adds a new workaround for rare issues where macOS could quit the application due to file management problems if any of the "top 5 processes" features was enabled by the user.

- To provide a permanent control menu at a known location, System Monitor now adds an additional application icon to the menu bar. This makes sure inexperienced users always have a base menu easily accessible. Pro users can remove this icon to save space. - When switching between full user interface and operation in the menu bar only, the app now shows an additional notification that explains the change of control mode. Experienced users can disable this notice. - To reduce flicker during startup, the application no longer tries to temporarily open its control window. - Fixes a problem where spacer elements have not always been shown with the same picture quality in preview bars. - Fixes a problem where diagnostic messages could be written to the system log when specific monitor items have been activated.

- Fixed a problem with the layout of specific numeric displays in the menu bar, where the font size or the total width could be slightly too large. - The animation effect when deleting elements from the menu-bar layout control has been made more consistent. - Fixed a rare compatibility issue with macOS 11 where the hierarchical table in the sidebar of the control window would not show all items or would not react to clicks on each of its lines.

- Added compatibility regarding symbol font changes in macOS 11.3 and future versions of macOS. - Added a FAQ section on autostart to the reference manual. - Corrected a build issue which resulted in the security features for "hardened runtime" not to take effect. The build was now created with a revised version of Xcode. - Fixes a rare memory management issue caused by an undocumented change in macOS Big Sur. This could result in unexpected program termination if any of the "top 5 processes" features was enabled by the user.

- Fixed an issue where a wrong item of the configuration window could be selected under specific circumstances. - Fixed some minor issues with the layout of the configuration window. - To avoid problems with the service management of macOS, which could launch the menu-bar part twice or could unexpectedly duplicate menu-bar items under specific circumstances, the app no longer uses separate processes for configuration window and menu-bar.

- Fixes a problem where the widths of some menus was not correct under specific circumstances, which could cause labels to be clipped unexpectedly. - Fixes a problem where header cells could be mistakenly shown for tables in the activity pane of the configuration window. - This version further ensures that the presentation of temperature sensor values has a similar level of detail on Macs with Intel(R) and Apple Silicon processors.
