On as administrator and couldn't open my own files within my own Documents folder. (A quote from Apple is not research.) I jumped from Snow Leopard to El Capitan (supposedly a supported action), and El Capitan created hundreds of permission problems. Perhaps you should do more research before making such a sweeping statement.
In El Capitan Safe Boot fixes a lot more things that can go wrong than previous versions of Mac OS. Regardless of the technicalities, just know that doing a Safe Boot is both diagnostic and curative. My personal favorite is Drive Genius, but there are several others. If you want more detail about what's going on while your file system is being repaired you can use a disk utility to perform disk maintenance. A messed up directory or catalog B-tree can cause symptoms that can be mistaken as permissions problems. You don't get to see what was broken and what was fixed during a safe boot, so any of these problems fixed during a safe boot can result in a Disk Utility runs and fixes directory problems and other problems with files, catalog B-tree, and more. The system font cache is emptied, so if a bad font was cached it isĭismissed. Among them: only a limited number of fonts load, so if you have a bad font it won't come into play.

Microsoft, software installers, have always altered Permissions when installing. This would be true and could even be removed altogether except for Microsoft products. It seems Apple has decided either through misinformation, or their own choice, people are unnecessarily repairing Permissions. Where permission are automatically fixed. To repair permissions now, you must restart computer in In fact Disk Utilities has been renamedįirst Aid and does all other task that were in Disk Utilities. As of El Capitan Repair Permissions is No long in Disk Utilities.
