从MAMP切换到MAMP Pro，无法启动mysql

Question

I was using MAMP successfully, then once I needed to have more than one local dev environment, I purchased and downloaded MAMP Pro. Now, mysql won't start in MAMP Pro, but still works correctly in MAMP.

Here is the mysql error log:

Answer 1

I uninstalled MAMP and MAMP Pro using the uninstaller found in MAMP Pro. I removed all files by dragging the apps into the trash and emptied the trash. I reinstalled a new MAMP Pro and mysql is working as expected.
