synching machines...

I sent my iMac to Apple for repairs and in the meanwhile used a "spare" MBP that I loaded with the Time Machine
backup of the iMac.

Now, I'd like to update the contents of the iMac without having to reimport the whole account and the GBs of
data it has.

Is there a relatively simple way to do that ?

The short answer for me is, I don't know.  Poking around the web a bit
indicates that the hyperthreading doesn't show unless the system is under
load, but I have no first hand experience to verify this.

I now have twice as many CPUs!

Hi,

My Mac Pro has a pair of quad-core CPUs, but both iStat Menus and MenuMeters show a bar chart with 16 bars
rather than the expected 8 bars.  Is this a Lion thing?  There were only 8 bars under Snow Leopard.  Why does
Lion seem to think I have 16 cores?

Even Activity Monitor seems confused.  It only shows 1 (cumulative) bar in the icon, of course, but
yesterday when I was doing something intensive, the activity panel showed a percentage over 1000%, so it
also appears to be acting as if I have 16 cores (or else the percentage would never exceed 800%).

I doubt that any of this is important, but I am curious.  Any thoughts?  Thanks,

Gregg

wireless network connectivity weirdness

		I have quite a few problems connecting wirelessly with my laptop, lots of minor weirdness. But the most
persistent one, easy to workaround but annoying is this— quite often, I connect to a new wireless
network, the normal wireless network login dialogue box appears, I fill it in and hit connect, it spins it
wheels for a few seconds (and wireless signal indicator does the 'up and down' thing), and then says
'Connection failed', then a few second later the connection appears to be working fine (wireless signal
strength indicator stabilises, network prefs pane shows it has acquired a dhcp IP), but the dialogue box
is still saying failure to connect. I then hit cancel and it goes away.		
	But sometimes it repeatedly fails, and I have to keep trying it eventually it works. 
	Anyone know what this might be? Nothing particularly useful in the console logs. 
	Cheers
		David

clean out the dust! It can get expensive if you don't


So, I have a Mac Pro (early 2008) with an Nvidia Quadro 5600 video card.  While it has reasonable airflow, the
Mac Pro itself is heavy, and it was behind a monitor on a table that was hard to easily get at it.  So I did not
blow out the dust often and never really in the video cards (also has an ATI 2600 card).

Lately I have been having occasional glitches when the card gets pushed hard, and more likely when the room
is warm than cold.  I've been thinking that I should take the computer, blow all the dust out, as well as off
(out of) the video card.  But I've been busy -- real busy -- the last week or two and did not  get to it, even when I
thought I should make time.

Well, yesterday I was down in my basement working on some stuff (moving tables from an office to the man-cave
:-) ).  I came back up  and the Mac Pro was off.  I did not remember putting it to sleep and it is not set to go to
sleep automatically.  (Though I do put it to sleep manually, the last few months, when I am away for a longer
period).  The light [power led] was on like it was sleeping, but not pulsing.  The monitors (Apple monitors)
were sleeping.   I tried to wake it up.  No go.  Finally I got all the cables disconnected and took it in to the
kitchen, and opened the side.  A thin layer of dust but not as bad as I have seen some computers.   I took it out
back on the porch and my cans of compressed air as well, and gave it 10 mins of blowing in every conceivable
nook and cranny to get all the dust out.  

Still no go when trying to boot.  You could hear some sort of relay or something go when you plugged it in, and
see the fan on the Nvidia card try to move, but it would not start.   I took the card out and blue out more dust
from it.   Then I saw the internal ducts in front of the heat sink were basically totally clogged.   I got it all
blown out.  The ATI card as well.  Put it all back together.  Nothing.   Replaced the MB battery (CR2032).  No go. 
Finally I removed ALL PCI-E cards and trued, and it would start up.  (No video obviously so I quit the startup
after showing it would start).  So I tried each card one at a time.   The ATI worked.  The Nvidia not.  :-(  It was
the main driver of my 30" screens.  I've ordered an ATI 5770 Radeon overnight delivery to replace the
Nvidia, but the cost could have been avoided if I had just dusted it out and cleaned out the video card once in
a while.   The Nvidia 5770 should be a lot faster and get around an OpenGL Nvdidia bug that makes 1/2 the
websites out there crash the WebProcess stuff in Safari, but with overnight delivery and one third party
display-port-DVI adapter, it was almost $290 -- money I did not need to spend if I had done a better job

Advice on moving to iCloud?


Hi All,

I am planning to move our family from MobileMe to iCloud and would like any advice or suggestions you may have
on how to make it painless, so I won't end up saying - oops I should have done X, Y, or Z.	Currently, this is
primarily for my wife and I but we have two boys moving into their teens so I need to keep that in mind.  My wife
and I share one MobileMe account so we can share Calendars and Contacts on all Macs and iOS devices etc.

We currently have the Family MobileMe deal with each of us having a @mac.com / @me.com account, but we don't
really use Apple's email service - we have our own email server (see server details below).  My plan is to
setup one iCloud account for each person in the family BUT to only use my iCloud account on all our devices at
present.  The boys don't have iOS devices yet or use Calendar or Contacts yet so we can all share these.

We have purchased media and apps from the iTunes Store using each of our MobileMe accounts (and the few
international accounts I have) BUT the vast majority of stuff has been purchased using my account and we
only do that now.  My plan is to continue to use just one (my) iTunes Store account for purchasing media and
apps from the iTunes Store going forward - it seems silly to pay for something more than once ;-)

Does that sound reasonable?

Two possible hitches and questions that I can see:

1.  Our SOHO server is currently running Snow Leopard Server and I don't wish to "downgrade" to Lion Server. 
We currently store our family iPhoto and iTunes libraries on the server but usually access from client
machines.  

My question is:   What problems will this cause (if any) on the SL Server?  We don't generally use the server
directly but, as I mentioned, it does hold our iPhone and iTunes libraries.

2.  My wife (bless her ;-) is still using her original iPhone 3G (at a glacial pace).  We plan to get her a new

what in the world did I mess up now...

Hi,

Last week I moved from a Snow Leopard machine to a Lion machine.  I thought I checked out my primary software
before finalizing the move, but apparently I did not check carefully enough.

I run SAS (statistical analysis software) remotely on a linux box.  Someone wrote a script for me that
basically allows me to submit my SAS code (and my data) to the linux box and then sends the output back to me.  I
know this is clunky, but it has been working fine for many years, under Snow Leopard, Leopard, Tiger, and so on.

When I first moved to Lion, I tried running a SAS program and it seemed to work.  It turns out that if I do not edit
the SAS script, it will run, but as soon as I make a change and save the file, it will not run.  I get the
following error message:

-bash: ./nlin.csh: /bin/csh: bad interpreter: Operation not permitted

I submit the job by typing "./nlin.csh" in a terminal window, where nlin.csh is the name of the script that
runs my SAS code.  I can edit the file with the SAS code and everything still works, but if I edit the script
file (even just typing a character and then deleting that character), I get the above error.

If anyone can help me with this, I sure would appreciate it.  If you need more information, please let me know. 
As you can tell, I don't know much about UNIX and scripts.

One last thing, which may not be relevant at all, but I did notice that the owner seemed to be fine on my user
files, but the group was not.  On my old machine the group was "staff", but on the Lion machine the group was
"admin".  I used chown to change the group from "admin" to "staff" but it did not solve the problem.  I used the
following command:

chown -R :staff dinse

where dinse is the name of my home directory.  I hope I did not make things worse.  Nothing exploded, but the

does Time Machine no longer use backupd?

Hi,

In my ongoing quest to monitor how long my Time Machine backups are taking, I had been able (under Snow
Leopard) to use the Console app to search for any logs that mentioned "backupd".  This allowed me to see when
the backups started and ended.

When I search for "backupd" under Lion, I find no matches.  What does Time Machine use to do its backups in
Lion?  In other words, what should I search for in Console app to monitor Time Machine backups in Lion?

Thanks,

Gregg

Little Snitch

Hi,

I seem to be full of questions lately...

I thought I had always heard good things about Little Snitch, whose purpose I believe is to monitor all
incoming and outgoing network connections.  It was on sale last week, so I bought a license.  Today I
uninstalled it because it was driving me crazy.  Anytime I tried to do anything, I would get a panel popping
up that asked whether I wanted to deny or allow a connection, either now or always.  Often I would get 10-20
panels in sequence.  It was difficult to get anything done.  In fact, it seemed to virtually prevent me from
using Screen Sharing because the popups never stopped and I could never connect to the other machine.  I
thought that after I said "always allow" to enough popups that their frequency would decrease after a few
days, but it did not seem to work that way.

Was I doing something wrong or did I need to change certain settings?  Do other Little Snitch users spend all
their time dismissing popups or does this eventually calm down over time?

Thanks,

Gregg

imagent: [Warning] Received memory warning, dispatching to listeners

I see this printed to my console a lot.  And usually when it's printing to the console, I hear a lot of hard drive
activity (unfortunately, my iMac doesn't have an SSD).

4/27/12 4:54:21.179 PM imagent: [Warning] Received memory warning, dispatching to listeners

I was thinking it might be the Messages beta app or SKYPE, but even after quitting these apps, I'm still
seeing messages to the console.

Anyone know which app is causing this warning?

USB modem and Lion

Hi,

I have an Apple USB modem, which was attached to my Snow Leopard Mac Pro.  When I switched to a new Mac Pro
running Lion, I connected the modem, but I got an error message when logging in (or booting?) that said it
was not supported under Lion.

I can't remember if the message suggested that no usb modems were supported or just this specific model.  In
the system profiler, I see the following message when I click on Modems (under the Network menu):

"No Apple modem found. If the Modem is external, make sure it’s connected via USB."

This message suggests that an Apple USB modem should work.  Does anyone know which is true?  Should an Apple
USB modem work on a new Mac Pro running Lion (10.7.3) or not?

Thanks,

Gregg
