Do I have to run the OS (10.6.3) in 64 bit in order to get full 64 bit benefits of PS CS5?

I keep reading about the benefits of running PS in 64 bit, especially for very large files (which is most of my work). I was under the impression that applications can only use more than ~ 3GB of memory if the operating system is running in 64 bit mode. However I still run mine (Mac OS 10.6.3) in 32 bit (the default mode) and still, in the "Performance" preference panel of PS I can allocate my entire amount of RAM (14GB) for Memory Usage.
Am I getting the full benefits of 64 bit or do I have to run my OS in 64 bit?
Thanks for any bit of advice...

By default Photoshop runs in 64 bit mode. If you want to switch between 32 and 64 bit then you would need to select Applications\Adobe Photoshop CS5\Adobe Photoshop CS5.app and then press Cmd + I, or click "Get-Info" from File menu.
In the Info panel, there would be a checkbox Open in 32 bit mode. Click that and Relaunch Photoshop. It will then run in 32 bit mode. Do reverse(Uncheck that) to run Photoshop in 64 bit mode.

How do you upgrade OS X 10.4.11 tiger to a higher version of operating system such as OS x 10.5.6 as have tried running the upgrade disc on imac 5,1 with intel processor but only get message saying this cannot be installed with no further explanation ?

Retail Leopard disc looks like this;
(The disc itself has the same logo). If the one you've got is grey it simply won't work.
Given the retail and second hand prices of Leopard (usually some on Amazon MP), you'll probably find it cheaper to go directly to Snow Leopard, although there could be software updates and printer driver problems that could nullify the difference.

My wife and i have an iPhone 5 6.1.2 firmware.. We both are having horrible wifi signals. We have done everything we can.. What update will fix this? I get full bars on my iPad 2 through my whole house.. Be standing right beside the router with iPhone NO

My wife and i have an iPhone 5 6.1.2 firmware.. We both are having horrible wifi signals. We have done everything we can.. What update will fix this? I get full bars on my iPad 2 through my whole house.. Be standing right beside the router with iPhones and it cuts in and out.. Drops from 3 wifi bars to 1

I am having the same problem with brand new Ipad Mini at my house.
It connects to the WiFi fine - but will not pull an IP address in DHCP mode, or if I set all the IP info statically - it still will not get any network access.
This doesn't look like a WiFi issue, as it does connect and is seen by the WiFi Access Point. All the normal WiFi fix stuff doesn't help.
- Using a Dlink DAP-2553 which is less than 2 months old.
Other devices connect fine, including Ipad 2.
This same Mini worked fine at another house and also connected to a mobile hotspot fine....so seems to be some weird IP issue with maybe this Access Point or maybe the older Router that I have (older Netgear)?
I am actually a network engineer and still have not been able to find a solution. Both the Ipad Mini and the Dlink WAP have the latest firmware loaded.
Wondering if anyone has found a solution to this problem.

Swipe through your screens and swipe to the left of your Home screen. Type in App Store in the search field. It's a permanent pre installed Apple app so it can't be deleted.
If you can't locate it on the iPad for some reason, connect the device to your computer. Right or control click the iPad under Devices left side of the iTunes window then click: Restore from backup

HT1923 I have just run the latest up date on my ipod & every thing from my ipod has disappeared, its telling me that it does not recodnise my ipod

I have just instaled the new update for my i pod, the screen on my i pod has usb symbol & i tunes symbol nothing else. The computer is tell me that i tunes does not reconise my i pod, that my i pod is on windows only, can't find it there either.

Here is what worked for me:
My usb hub, being usb2, was too fast. I moved the wire to a usb port directory on my pc. That is a usb1 port which is slow enough to run your snyc.

I have problem running the inverted pendulum trainer using NI ELVIS.

i have a problem running the inverted pendulum trainer using NI ELVIS. While loading the NI ELVIS bypass VI it is unable to find the "enable communications bypass.vi". could anybody please attach the VI.
I am using NI ELVIS 2
Thanks

The Enable Communications Bypass VI sounds like a VI that is only included with Traditional or legacy ELVIS designed to work with the first generation ELVIS unit, not the ELVIS II/II+ or myDAQ. It sounds like the inverted pendulum trainer you have is for use with ELVIS I. In the LabVIEW Loading dialog, do you see the full path for where it's looking for the VI? Can you provide that full path? If the inverted pendulum trainer is designed to work with the older ELVIS unit, there may be a newer version that supports ELVIS II.

Don't have to run the report for no prompt value

Hi,
The requirement is that I need to create a report which is more of a search report kind of thing. So on the dashboard we need to show only prompts. The users would choose any prompt and run the report.....now the issue is....that when no prompt values is selected and user hit the GO button ..i need to show a message saying "Please select any value" ...how to do that ..
I have already refered kishore's blog on guided navigation to implement this ..but the issue which I am facing is that my intermediate report is taking too much time (almost 10 mins) to come back with values and then my actual report shows the message thorugh No results view ...but i need to load the messsage to the dashboard in not more that 1 mins ...how to do that .....
any help would be much appreciated ....
Thanks
Ronny

Thanks Kishore, but I have already refered your blog and implemented this approach as I have mentioned above, however, the issue is that my intermediate report in which I am using the dummy filter is taking too much time to run ...like 10 mins...so guided navigation doesn't work properly ....I have almost 15 prompts so it is taking time ..is there any other work around ?
Thanks,

please help with blocked plug ins i have down loaded the latest version of abode several time and am not getting anywhere this seems to be an ongoing problem when i get updates from them

When you download from the Adobe site, despite the button saying “install” — it really doesn't do anything but download the installer.
Quit the Safari browser. Next to the Trash icon on your Dock, is an icon that is an alias to your Downloads folder. Click this icon once. There will be a list of previous downloads that pops up. The file closest to the Dock is the Adobe Flash installer. Click this once to launch it. It will display like this:
Double-click the red flash folder. This produces the following dialog — you select Open.
You will receive a password challenge. Use your Mac OS login password. You next prompt will look like this. Choose the middle selection as I have shown:
The Adobe Flash Player will download and install via a blue progress bar. You will need to click a Finish button, and then Safari launches taking you to the Adobe site to verify Flash Player was installed.
In System Preferences, the bottom panel now has an Adobe Flash Player preference panel. It has an Advanced tab that enables you to check if there are newer releases of Adobe Flash available, and it wil also fetch the installer for you (usually). The System Preferences panel, and Safari must both be closed for Flash Player updates to succeed.
Eject the Adobe Flash Player installer from your Desktop.
Once Flash Player is installed, you may need to open Safari Preferences > Security, and check Internet plug-ins: Allow Plug-ins. Click the Manage Website Settings… button, and then select Adobe Flash Player in the left panel of the pop-up. You want Allow set When visiting other websites. Click Done, and close Safari Preferences.

My battery needs service as it is not working for long. Apple claims it is not a defective battery and that it is my fault since I had the computer for 2 1/2 years and have only run the battery down to empty 100 times. It is my fault because I did no

Con't
Apple claims that because I did not drain my battery frequently and kept it plugged in for extended periods of time, that it is my fault the battery is failing. I disagree because I was not ever told to consistently drain my battery before recharging or not to keep it on and plugs in for extended periods of time. I do keep my desktop computer on most of the time and that is why I have kept my Macbook air on for extended time periods. I feel that Applecare should cover this battey issue and not charge me for replacing the battey. I feel I should have been told to not keep my computer consistently running on with poweror the battery will fail. Has anyone had this problem? Apple should replace my battery under Apple care as my battery does not keep a charge anymore.
I'll wait to hear.

You said---Apple claims that because I did not drain my battery frequently
You said--- I was not ever told to consistently drain my battery before recharging
You should never do that on purpose, whoever told you that had it wrong or you misunderstood something
Sure you dont have that backwards? thats exactly what you DONT want to do.
Did you often drain the battery very low? that would explain a lot.
Someone might have been misinformed about "battery calibration" regarding much older Macs with removable batteries (see bottom)
You said-----I do keep my desktop computer on most of the time and that is why I have kept my Macbook air on for extended time periods.
thats a problem there, youre not supposed to do that.
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
*If you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
And best "tip" is if its near a socket,...plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)", however again, not plugged in all or most of the time.
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
From Apple on batteries:
http://support.apple.com/kb/HT1446
http://www.apple.com/batteries/
Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace
Battery calibration, battery memory, battery overcharging, battery training, …all these concepts are mostly holdovers from much older battery technology, and on older Apple portable Macbooks ranging from early nicads, NiMh and otherwise; and these practices do not apply to your lithium battery and its smart controllers.
Calibrating the battery on older Apple portable Macbooks with removable batteries.
http://support.apple.com/kb/PH14087
There is no calibration of current Apple portable Macbooks with built-in batteries.
http://support.apple.com/ht1490
There is no battery calibration with current Apple portable Macbooks with built-in batteries. Lithium batteries have essentially a 0-‘memory’, and all such calibration involve the estimations fed to the system controller on the SOC (state of charge) of the battery over long periods of time as the battery degrades. The software based battery controller knows the battery's characteristics, or SOC and adjusts itself. This is why there is both no need and purpose to periodically deeply drain your macbook battery, since it doesn’t affect the characteristics of the battery, and further still deep discharges are something you should not do on purpose to any lithium battery.

Why do I have to run the plug-in container in my processes constantly in this version? It takes up too much memory!

The earlier version of Firefox did not run this plug-in container. Every time I would remove it from my processes it would kill videos etc. But, it was all fine in the older version of Firefox, so why the change? So I chose not to update Firefox. Then, the other day, I saw that is was automatically downloading and I turned off my computer because it wouldn't stop and I didn't give permission. When I got home I could not use Firefox and it took me hours to figure out how to get the internet back. Then I got Firefox back and this stupid process is running again. It takes up too much memory. I don't like a bunch of extra processes running like that. So, why can't I just use the old version? Is this process absolutely necessary?

In the past the memory usage would end up as part of the Firefox program. Now with OOPP you can see it as a separate process and that makes it more noticeable.
You can disable OOP if you want.<br />
