Repairing the permissions of a home folder in Lion is a complicated procedure. I don’t know of a simpler one that always works.
Back up all data now. Before proceeding, you must be sure you can restore your system to its present state
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the page that opens.
Drag or copy — do not type — the following line into the Terminal window, then press return:
chmod -R -N ~
The command will take a noticeable amount of time to run. When a new line ending in a dollar sign ($) appears below what you entered, it’s done. You may see a few error messages about an “invalid argument” while the command is running. You can ignore those. If you get an error message with the words “Permission denied,” enter this:
You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up.
Next, boot from your recovery partition by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the recovery desktop appears, select Utilities ▹ Terminal from the menu bar.
In the Terminal window, enter “resetpassword” (without the quotes) and press return. A Reset Password window opens. You’re not going to reset the password.
Select your boot volume if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select ▹ Restart from the menu bar.
Hi, I am very grateful for the rapid response to my question. What puzzles and disturbs me, however, is how and why this is required: I have not done anything other than surf the net, install Microsoft Office and create/open/edit a couple of Word documents and open a few .pdfs - how/why do I find myself in this position?
This is really disturbing and I'm not convinced I like the idea of the steps that I have to take to resolve this. I have been an iPhone user for over 3 years and have found it inuitive and rock solid; very user friendly. Likewise with my iPad 2 that I have had for a litte under a year... but the MacBook - nothing seems easy or inuitive and I have absolutely no idea how or why I find myelf in a position where I am having to perform some sort of laborious factory reset. I just don't get.
Disappointing and frustrating - but thank you for your help Linc Davis... I'm not sure I'm confident enough to try this though.
What I find mystifying is the fact that I have now discovered that some .pdf's are still "savable" from preview by way of "save a version".
Could it be thatthe .pdf's from this particular site have now been protected with some sort of copyright protection (even though I have a license to save documents from this particular site)?
There must be some kind of protection code as I too have had the same issue. It sometimes will not allow the print window to show a preview of the page and will only print a blank page. I get around this by copying and pasting to something like Pages or I take a selection screen shot (shift-command-4) and save it as a pdf via print command.
