Truecrypt for Mac在OSX 10.10反而不能安裝問題

Truecrypt 7.1a for Mac在OSX 10.10.3反而會顯示需要10.4以上才能安裝，估計是一個bug。


網路上找到解決方案：

方法一成功了，但比較麻煩。

方法二好像比較簡單，但不知道怎麼解決唯讀問題。


以下節錄上述網站：

First method

• Open the .dmg
• You’ll find the .mpkg. Right*click and “Show Package Contents”
• Open Contents Dir
• Open Packages Dir
• Install each of the 4 packages in this order: OSXFUSECore.pkg, OSXFUSEMacFUSE.pkg, MacFUSE.pkg, TrueCrypt.pkg (It is possible MacFUSE.pkg will install the two before it, but we ran each to play it safe.).

That’s it; it’s Truecrypt has been working fine for us using this method.

Second method

• Open the .dmg
• You’ll find the .mpkg. Right*click and “Show Package Contents”
• Open Contents Dir
• Edit Contents/distribution.dist using Text Editor
• You'll find the code as below
  function pm_install_check() {
•   if(!(system.version.ProductVersion >= '10.4.0')) {
•     my.result.title = 'Error';
•     my.result.message = 'TrueCrypt requires Mac OS X 10.4 or later.';
•     my.result.type = 'Fatal';
•     return false;
•   }
•   return true;
• }
• 
  
• change it as follow:
  function pm_install_check() {
•   return true;
• }
• 
  

Now, you can install .mpkg without error.
