IDEFRAG FOR MA PRO
There are three third party utilities Drive Genius, TechTool Pro and iDefrag will perform actual file and/or disk defragmentation on OS X. However, both of these built in functions tend to increase disk fragmentation. There is another function where files in a certain size range are automatically placed on contiguous sectors. There is one function called hot banding where the most often used files, almost always system files, are identified and automatically move the that part of the hard drive that offers the fastest access. There are some automatic features in OS X that do at least some of that, on the fly.
It resets the ownership and permissions of the OS X Systems files and those applications that have installed Reciept packages with a bill of materials (BOM) in /Library/Receipts.ĭefragmentation, reordering of files so they are on contiguous disk sectors and/or removing all the gaps between files is a completely different process. The repair permissions function in Disk Utility does exactly that. Repairing permissions is in no way the same thing as defragmenting a drive. There is a built-in application to do this called 'Disk Utility' which you can find here.
Firstly, using the Mac OS, we would call it 'repairing permissions'.
