I've occasionally run into this issue with migrated accounts. Fixing it takes a 
bit of Terminal-fu but it’s a quick fix.

Start terminal

You will be in your own home directory, so enter:

cd /Users

and hit return.

Then type

ls -l

And hit return (those are the letter ell not ones)

You will see something like:

dbdev2:Users johnson$ cd /Users
dbdev2:Users johnson$ ls -l
total 0
drwxrwxrwt   18 root   wheel612 Aug 28 18:03 Shared
drwxr-xr-x+  11 helpdesk   staff374 Aug 28 11:01 helpdesk
drwxr-xr-x@ 244 johnsonstaff   8296 Aug 31 07:51 johnson
drwxr-xr-x@  11 macports   staff374 Aug 28 13:48 macports
drwxr-xr-x@  11 927885439  1391123018   374 Aug 28 13:54 thushara

Depending on how many user accounts you have on the Mac. Note which one is your 
home directory; in my case it’s ‘johnson’, and note what the 3rd and 4th 
columns are, this is your short user name and primary group name, respectively. 
Mine is ‘johnson’ and ‘staff’ yours may be different.


Now enter enter:

sudo chown -R  username: group /Users/username

Substituting the user and group name noted above.

In my case the command would be:

sudo chown -R johnson:staff /Users/johnson

Here is an example of what happens when you do this. You will be prompted for 
your password. NOTHING will show on the line, if you do it wrong the command 
will fail with the error :

Password:
Sorry, try again.

If this is the first time you have ever used the ‘sudo’ command you may see 
some texts saying, essentially ‘be careful’ (1).

Like most Unix command line commands, if the command succeeds, you’ll simply be 
returned to the command prompt; you’ll only see a message is an error occurs.

dbdev2:Users johnson$ sudo chown -R helpdesk:staff /Users/helpdesk
Password:
dbdev2:Users johnson$


What this command does is:

sudo : Makes the system run this command as the root user, being an 
Administrator on the mac makes your account one that can use this command. The 
root user is all-powerful and can do anything to any user account on the system.

chown : Change ownership Almost always when you have an issue like you don’t 
have permission to access a file in your own directory after a migration, it’s 
because of some error in assigning ownership of the migrated files to the 
proper owner in the new system.

-R: apply this command recursively, ie: apply it to all files and folders in 
the targeted directory

username:group : the username and group who will be assigned the ownership

/Users/username : the directory you want to apply this command to.



Repair Permissions in Disk Utility does NOT do this; the permissions it repairs 
has to do with Applications and System software only. I have only ever twice in 
my career actually run into a problem where running Disk Permissions actually 
fixed the problem I was having. Fix Disk Permissions was really only ever a 
tool that was stuck into OS X starting with OS X 10.2 to fix a problem that 
only really existed in OS X 10.1.5.

We trust you have received the usual lecture from the local System 
Administrator. It usually boils down to these three things: #1) Respect the 
privacy of others. #2) Think before you type. #3) With great power comes great 
responsibility.

 but at some point Apple removed that verbiage, probably because Marvel 
objected.)

Did you repair them?
You can do it using Disk Utility:

You didn't tell us which model your Mac is.
When troubleshooting, one should give two info first: Mac model and OSX
version he's using.

Anyway I think your Mac (iMac? Mac Pro?) could maybe better run with an
older OSX version, like Snow Leopard (10.6) or Mavericks (10.9).

With an older version you might be more exposed to malware.
OTOH, your Mac should likely be faster, less memory-hungry, and you might be
more lucky with running older software and hardware.

If your hard disk is big enough, you could create another partition and
install the older OSX there. This way you cold boot into each OSX, according
to what you need to do.

Migration to Intel

[smac0031]

My G5 recently died. I bought and ancient intel.

I tried using the Migration Assistant to migrate from the G5. I kept 
getting and error that the G5,
running 10.5.8 I think, the most advanced system X needed to be upgraded. 
Obviously not being
possible I took the G5 drives and put them in the Intel and I was able to 
migrate that way.

I still have problems with permissions. For instance the Intel won't let me 
into my music folder
telling me I don't have permission. I'm fairly sure I'm using the system 
administrator account so 
I don't get it. There are other users in the user section of the system 
preferences but they are 
dimmed.

Another problem is with my ancient Brother HL-1440 printer. It's extinct 
but it still works fine except 
not with this newer computer. I downloaded something called a CUPS driver 
and the directions.
I enter the first command in Terminal and then it goes nowhere. There are 
supposed to be
printer choices depending on the drivers installed. There are none. 
According to the documentation
this drive is supposed to work with this computer and this OS and this 
printer. There error I get
is there is no printer connected.

I also have and Epson V300 scanner which is a nice scanner. It has control 
buttons one of which is
the power on/off and another which automatically scans PDFs. That was 
really handy. Naturally this
doesn't work now. I got the latest driver for it and the I have to use the 
software in a work around
and the first page is always more or less square and every other page 
afterward is crooked no
matter what I do. My late Father did a genealogical study of our family and 
I'm trying to scan the
damn thing. There are over 150 pages and this is not working.

Also this thing is running El Capitan. This is one of the early PowerMac 
how advanced system
software should I upgrade it to. This is a legacy computer and I am used to 
running legacy
software and I don't want to get things out of whack. My favorite computer 
was Digital Audio G4
which died earlier this year there was limited software for that thing, but 
keeping it 
contemporaneous seems to work.

Thankyou Mark M
