1、下載地址
https://www.eclipse.org/mat/downloads.php
2、開啟彈出下面對話方塊
3、檢視日誌如下：
java.lang.IllegalStateException: The platform metadata area could not be written: /private/var/folders/js/9_2jl105695f5tqf4pfl7xzr0000gn/T/AppTranslocation/F356ED05-60E9-4756-B644-EB4670F5B797/d/mat.app/Contents/MacOS/workspace/.metadata. By default the platform writes its content
under the current working directory when the platform is launched. Use the -data parameter to
specify a different content area for the platform.

4、解決辦法
這是eclipse的一個bug，記錄地址：https://bugs.eclipse.org/bugs/show_bug.cgi?id=339647#c5
解決辦法: 右鍵mat顯示包內容，進入Contents->MacOS下面，會有一個MemoryAnalyzer的命令。
開啟終端，進入此路徑找到MemoryAnalyzer，執行
./MemoryAnalyzer -data dump檔案所在資料夾路徑
即可啟動成功
