It was a nuisance and there were things in my Trash Bin I needed to recover and under the necessity for a password, no files were showing in the Trash Bin. Once unlocked I could once again access them.

Apple Support solved this for me. I'm a Mac novice so I may not say this in 'mac-eese'. The first sequence of steps took about 5 or so minutes and it did nothing (that I know of), but follow along anyway - it's just a handful of minutes. First they had me open Disk Utility and run a few checks. That did nothing, but just in case, you can run these steps: Go to Applications/Utilites and select Disk Utility.

Run Verify Disk and Disk Repair (if needed). Then run Verify Permissions and Repair Permissions. This took a fair amount of time and I received some kind of ACL issue and then it said it was repaired.

As a side note, it wasn't because it also happened the second time I ran Repair Permissions. Next came the steps that worked and I'm not sure if the previous steps are required or not.

From the basic 'home' screen without anything running other than Finder, select the 'Go' command in the top row of your screen and select 'Home' from the drop-down menu. A Finder window will open that should have a little house as the icon. Once that appears, press 'Command i' (command button and the letter i). This brings up an Info window for Home.

In the preview section of the Info window you should see the House icon. If you don't you are not in the right place.

At the bottom of the Info winow select/highlight Computer Name (me); where Computer Name is whatever you named the computer. Regardless of the name, '(me)' will be next to it. To the right on that you should see read/write. If not, change it to read/write for that row only. At the bottom right, unlock the lock (click on it and you proably need your password to unlock).

At this point the lock should be unlocked and your computer name is selected/highlighted. Click on the gear wheel and select the option 'apply to enclosed items'.

It may take a short amount of time for the computer to repair or apply the setting to your items (which should be everything). After that, everything was back to normal. This second sequence of steps takes about one minute to do. Michael I used your 'sudo chown' etc to fix the deleted file into trash, on my new Lion OS, and it worked. Thanks very much.

Now I find another glitch elsewhere. If I try to move a document or file etc onto the hard drive icon with Lion I am now asked to authenticate and have to type in my password each time for it to move on to the hard disk. I didn't have to do that with Snow Leopard. What is the answer please? Is it another set of words into the Utilities folder? If so what are they and what do I do? Michael Thanks for that.

Unfortunately despite carrying out your ideas to the letter. It doesn't work for me. If I want to move any file/doc/picture to the HD it still says 'doc etc can't be moved because Mackintosh HD can't be modified' It gives me the option to authenticate or cancel.

Obviously by clicking authenticate and putting in my password it allows me to put it into the HD. A pain of course. But it does work.

The other gliche I find on Lion is that if I go to the HD and bring up a doc or picture out of it, it has the name that I have given it, say' xyz', at the top of the item with 'locked' in grey letters next to it. If I then try to add or edit the item it says 'You don’t have permission to write to the folder that the file 'xyz' is in. You can duplicate this doc and edit the duplicate. Only the duplicate will include your changes.'

It gives me the option to cancel or duplicate. If I click duplicate the duplicate doc appears with the same name 'xyz' with copy in black next to it. I can then amend/edit it and once saved it has 'xyz' with edit next to it. Html5 css code. All very weird. I didn't get any of this on Snow Leopard.

Is this a new feature of Lion? Apple Footer • This site contains user submitted content, comments and opinions and is for informational purposes only.
