MAMP上的TYPO3无法登录安装工具(TYPO3 on MAMP can't log into install tool)

 在OS X上使用MAMP PRO 3.2.1在本地设置TYPO3 4.5.40站点（升级到6.2）后，一切正常 - 除了登录安装工具。 
 
 没有关于错误密码的反馈，只有超时后的错误500。 
 
 设置为CGI模式时，apaches错误日志显示： 
 
[Tue May 19 18:00:40 2015] [error] [client ::1] FastCGI: incomplete headers (0 bytes) received from server "/Applications/MAMP/fcgi-bin/php5.3.29.fcgi", referer: http://site.dev/typo3/install/index.php
 
 运行PHP作为模块，它仍然谈论fastCGI，奇怪的是： 
 
FastCGI: process manager initialized (pid 11681)
 
 它也没有帮助。 
 
 更改PHP版本或禁用OPCache也没有帮助（之前已通过CodeKit禁用了OPCache）。 
 
 我之前已经拥有它（使用6.2！），并通过在新目录中设置网站来解决它。 但如果这种情况一直发生，我需要知道原因。 
 
 我在哪里看？ 是什么让安装工具登录与BE登录不同，哪个工作正常？ 可能是MAMP的一些设置吗？ 

After having set up a TYPO3 4.5.40 site (for upgrading to 6.2) locally with MAMP PRO 3.2.1 on OS X, everything works fine - except the login into the install tool.
 
There is no feedback about a wrong password, only an error 500 after the timeout.
 
When set to CGI mode, the apaches error log says:
 
[Tue May 19 18:00:40 2015] [error] [client ::1] FastCGI: incomplete headers (0 bytes) received from server "/Applications/MAMP/fcgi-bin/php5.3.29.fcgi", referer: http://site.dev/typo3/install/index.php
 
Running PHP as a module, it still talks about fastCGI, strange:
 
FastCGI: process manager initialized (pid 11681)
 
It doesn't help either.
 
Changing the PHP version or disabling OPCache doesn't help either (OPCache has been disabled by CodeKit before).
 
I've had that before (with 6.2!), and solved it by setting the site up in a new directory. But if that happens all the time, I need to know the cause.
 
Where could I look? What makes the install tool login different to the BE login, which works fine? Could it be some setting in MAMP?
