I just had someone ask me about some folder’s they found on there system…  They were concerned that they folder’s in question where taking up a bit of space, and they wanted to clean up there hard drive…

For example:

• /Developer (from old Mac)
• /opt (from old Mac)

The common factor, was the “(from old Mac)”…. I was able to safely say that it was safe to remove the folders, assuming they had removed any data they needed from the folders…  Why could I do safely say that?

“(from old Mac)” is what the Migration Utility add’s to folders that it is copying over from your OLD MAC, when there is a naming conflict.

In otherwords, it didn’t overwrite the new developer tools that came with your new system, it gave the old copy from your old system a slightly different name by appending “(from old Mac)” to the folder name.

Yes, you can safely remove them, assuming there isn’t some data that you need from those folders…
