MCG at Mac App Store analyse

MCG lets you analyse your application profile data natively on macOS. With call tracing, function summaries, graphs and treemaps, you’ll easily be able to detect and correct any parts of your application that are taking longer or using more memory than they should. MCG requires callgrind profiling data for your application, which can be generated in many languages such as PHP, Ruby and Python, or can be baked in for compiled languages like C/C++. FEATURES: • Super fast parsing of most callgrind files, regardless of language. • Structural analysis graphs including call depth, class methods call count and cost, and function type. • Supports compressed callgrind and multi–profile files (supported by Xdebug 2.3+), and 10 ns (supported by Xdebug 3+). • Various treemap visualizations for MCG’s Outline and Flat data modes, including heat map gradients (please read app help for why treemaps aren’t accurate in profiling tools) • Outline call tree view for PHP Xdebug shows exact execution path/tree. • Click navigable to follow calls, treemap nodes and graph points. • Text search filter. • Generic cost support, including Seconds, Milliseconds and Microseconds for time costs, and MB/KB/b for memory. • Supports dark mode, macOS 13 Ventura, macOS 14 Sonoma, macOS 15 Sequoia, both Intel and Apple Silicon. • Did we mention that it's super fast? • The original native profiler for Mac. * Note that some technical knowledge of stack trace/call trees and code performance tuning is required to make use of MCG’s analysis and displays.
