You can normally go about your business and Mac OS X will take care of managing the proper file permissions as you create and modify files on your Mac. There are a few cases however, such as copying files from other user accounts, when file or folder permissions may get set incorrectly. This can cause a variety of issues and symptoms including the following. Simply select the file or folder in question and choose the Get Info command from the File menu or right-click on the file or folder and choose Get Info from the pop-up menu that appears.
This section is simply a graphical user interface GUI to display and control the underlying Unix file permissions system. In its simplest state these permissions consist of a set of single owner, group and everyone settings.
Examining the files permissions in the Get Info window will often show the following strange result, 2 entries for everyone with one of them set to custom. This second everyone entry is an ACL entry that causes the file to be read-only. Before making any changes to file or folder permissions you should first back up all data on your Mac. Is there maybe a Plist I can change to go back to 10?
I always had the impression that the critical number was related to your screen size - I'd get more info windows before switching to the summary window on my desktop than on my macbook.
For example, on my macbook, the new limit is 7 rows of 4 info windows, and then when I add the 29th item, it goes to the summary info window. On my Mac Pro, I get 60 items 12 rows of 5 before switching to the summary. That said, I agree that a smaller number would be useful. Perhaps should submit a bug report to apple, and could suggest that they add a button to the "summary info" window that would allow you to expand it to individual info windows. That way the default threshold could be quite small like 5 or 7 , and you could still get the individual windows easily enough if you wanted them.
It's just 34 for my 15" MacBook Pro. This hint brings back memories of the old days in Mac OS 7 where I would repeatedly use the Shift-Command-Right Arrow shortcut to expand the folder tree of my hard drive and then do a select all and get info. The screen would slowly but surely fill with a get info window for everything I had selected. A Command-Option-W after it finished would close everything, one at a time. Good times. A related tip is if you do option-command-i it will show an "Inspector" meaning it will show you the "Get Info" window on whatever you have selected at any given point it changes when you change selections.
Lost your password? This change is a welcome one, for it makes comparing more than one file or folder quite simple. But what if you want to get this same summary info for a selection of 10 or fewer items? The Summary Info window, as seen at right, will open. Alternatively, just use the handy Control-Command-I keyboard shortcut. So, instead, we can select both files together and then use a special form of the Get Info command to view the combined total size.
To select multiple files or folders in macOS , you can either click and drag over both items at once using the mouse or trackpad which is good for just a few items like we have here , or you can use the Command or Shift keys in combination with your mouse or arrow keys.
