App Tamer

What is new in this release:

• By default, App Tamer will now slow down Microsoft Edge when Edge is running in the background.
• Added support for Coherence and other apps that create site-specific browsers based on Google Chrome.
• A warning is shown when you slow down Spotlight, as this may adversely affect applications that depend upon Spotlight.
• App Tamer's performance has been greatly improved when apps like Epichrome or shell scripts make frequent, repeated calls to the sleep, kill, and lsof shell commands.
• If App Tamer is configured to run in the background (not showing its icon in the Dock), it will ignore Command-Q when its window is open so you don't accidentally quit it.
• Google Chrome apps are now handled correctly. If a Chrome app is configured not to slow down, Chrome will be kept running at full speed so that it can serve as the "engine" for the app without compromising the app's performance.

What is new in version 2.3.5:

• Resolved a problem with App Tamer progressively using more and more RAM when run for long periods of time.
• App Tamer's total run time, amount of CPU saved and the number of apps it has automatically quit are now shown in the Stats tab of its preferences.
• Localized application names are shown in the process list when they are available.
• The sorting of the Managed Processes list will no longer get confused when the mouse is over the list when it refreshes.
• Corrected problems with the menu button in the lower right corner of App Tamer's window becoming unresponsive under certain conditions.
• Fixed a bug that caused App Tamer to crash on macOS 10.8 and 10.9.
• Improved VoiceOver support.

What is new in version 2.3.4:

• App Tamer can now be set to quit applications after they've been idle in the background for a certain amount of time. Note that if the application pops up alerts about unsaved changes, etc, those alerts will still pop up. App Tamer doesn't auto-OK them or otherwise intervene.
• There were situations in which App Tamer's management of CPU usage could fail for apps that have multiple sub-processes, like web browsers and Spotlight. This issue has been fixed, so managed apps should stick more closely to the CPU usage you've set for them.
• When you turn on Time Machine Acceleration, App Tamer checks to see if Time Machine is also configured to be slowed to a particular CPU limit and will put up an alert to let you know that these settings are at cross purposes.
• App Tamer's own CPU usage has been reduced.

What is new in version 2.3.3:

• Added the ability to change a process' priority. While this generally doesn't make much of a performance difference, it can help when multiple processes are competing for disk or network access. Hold down the Option key while clicking on a process in the process list to access the priority slider.

What is new in version 2.3.2:

• App Tamer's window is now resizable.
• Fixed a bug that could result in App Tamer not correctly slowing a process even when it showed that it was managing it.
• Worked around a macOS issue that could result in App Tamer warning about an application's CPU usage even after being told not to.
• App Tamer's default settings have been changed: Preview and OmniOutliner will no longer be managed by default, Safari will be slowed to 2% CPU usage rather than being stopped in the background, and iTunes will be slowed to 10% rather than stopped.

What is new in version 2.3.1:

• If Spotify is playing music in the background, App Tamer will no longer stop or slow it down.
• Corrected a logic error that prevented App Tamer from correctly slowing apps that have lots of helper processes (such as Spotlight and Google Chrome).
• When Chrome and Spotlight are slowed by App Tamer, their CPU usage is now more steady.
• Fixed several small memory leaks.

What is new in version 2.3:

• New "Detection" feature that alerts you when an application or background process starts consuming excessive CPU time.
• Updated user interface that's consistent with the look of El Capitan and Sierra.
• App Tamer will no longer stop iTunes when iTunes is ripping a CD.
• When it launches, App Tamer now automatically quits any other copies that are running.
• All Spotlight indexing processes (and their aggregate CPU usage) are now displayed as a single task.
• Fixed a bug where App Tamer considered the frontmost app "in the background" when you clicked on App Tamer's icon in the menubar.
• Eliminated a crash that could occur when macOS supplies incomplete process information to App Tamer.
• App Tamer will never stop VoiceOver.
• Fixed VoiceOver support in the Quick Start windows.
• App Tamer now requires macOS 10.8 or higher.

What is new in version 2.2b3:

• Further improved efficiency on El Capitan and Sierra.
• Fixed a launch-time bug that caused crashes on macOS 10.9.
• Made contextual menus (when clicking on processes in App Tamer) behave consistently.

What is new in version 2.1:

• Compatible with El Capitan.
• Refined the logic that detects when App Tamer is having trouble monitoring Chrome's download activity.
• The AppleScript command for turning autostop on and off now returns the old setting as its result.
• Updated support for NetNewsWire, the App Store app, Go for Facebook, Leaf, Reeder and Fluid browsers.
• Improved "Show in Finder" so that it works with system daemons and other non-application processes.

What is new in version 2.0.5:

• If your Mac has more than four processor cores, you'll now get a dialog offering to change the cpu history graph to a logarithmic scale. This mode shows much more detail when cpu usage is a lower percentage of total capacity (which is very common because you're rarely using all cpu cores on 8 and 16 core Macs).
• Fixed problems with 64-bit Safari plugins not being stopped and started correctly.
• App Tamer now shows more helpful error messages when it can't connect to the internet to validate your license number.
• When installing its helper application, App Tamer will try to fix permission errors for you when it encounters them.
• When App Tamer reenables itself after being turned off for a period of time, it now displays a notification in Notification Center on Mac OS 10.8+ .
• Corrected a bug that would mistakenly hide both stopped and slowed apps when the "Hide applications when they are stopped" setting was turned on in your preferences. Now App Tamer doesn't hide apps that have just been slowed down.
• Improved the appearance of the CPU history graph.

What is new in version 2.0.4:

App Tamer has been updated to fully support Mac OS 10.10 Yosemite.

Limitations:
