Is there any benefit for me to use smart previews if my Lightroom 5 catalog, previews and media are all on the same external USB HD?

I keep everything on 1 External USB3 HD so that I can pug it into my Mac at home or my PC at work and just keep working without syncing anything to the local machine. So is there any benefit with Smart Previews in this case? I heard somewhere that it might make the Develop module a little quicker, but is this only when using the Smart Preview and not the full res image?

Lr uses smart previews instead of ACR cache for initial develop-module view when photos are online - amount of benefit is, in my experience, very minor (not noticeable without using a stop-watch..).
But if photos are offline, you may experience more substantial savings.
Note: smart previews are reduced resolution - smart previews of raw files are 2560 x (say) 1920, so if your original raws were say 5120 x 3840, then you/Lr are dealing with 1/4 the number of pixels when editing via smart previews.
Anyway, if you are willing to give up zoom for one edit pass, you can resize the smart previews so 1:1 fits in your allotted display space (e.g. 1280 x 960, which would be 1/8 number of pixels..), e.g. using the PreviewExporter plugin - then things may be significantly faster in develop module. PreviewExporter also has a feature to take originals offline, and put them back online.
To be clear: the amount of savings may or may not be dramatic - how much there is depends on your system, size of raw vs. smart preview image, number and type of edits applied, etc..
Why don't you try it and tell us what you think?!
Cheers,
Rob

HT5706 I just purchased an AppleTV and am trying to connect AirPlay with my mac (2012 model) In 'system preferences displays' an airplay menu is listed but it says 'no device detected'. My AppleTV and macbook are connected to the same network. Any help?

I just purchased an AppleTV and am trying to connect AirPlay with my mac (2012 model) In 'system preferences > displays' an airplay menu is listed but it says 'no device detected'. My AppleTV and macbook are connected to the same network. Any suggestions why it is not working?

Troubleshoot the network as that is likely what is causing the issue.
Also, temporarily disable the firewall on the Mac and disable IPV6 on the computer.

Using Premiere CC and Media Encoder CC at the same time

Is this possible? Doesn't seem to be. Media Encoder bails on every job as soon as you try to render anything in Premiere. I guess they don't play nice together, which is surprising. I was hoping that Media Encoder would pause and wait for Premiere to finish a render. Instead it dies on every render job, creating 0 size video files... while making a sheep bleating sound.
Is this a GPU issue? I have 2 nVidia cards, a 770GTX and 560GTX. (Windows 8.1, 16gb RAM, 3770k CPU)

As soon as I initiate a render in Premiere, Media Encoder bleats, and all subsequent render jobs bleat and produce 0 size video output files... even if I quit the Premiere render before Media Encoder reaches some of those render jobs.
I suspect this is a GPU sharing issue.... but can't be certain.
What do you mean by new install? Did I install it (AME or Premiere) recently? No. I've had Creative Cloud on my machine for almost a year, and both Premiere and Media Encoder have been updated periodically.
To my knowledge they have never worked together, but I only started using the queue feature within Premiere recently, so I haven't used AME until recently.

Mac Mini won't connect to internet using Apple products (Safari, iTunes, AppStore). Date and time are frozen to the moment CPU is booted up. Firefox works. Cannot update.

For the past few days my Mac Mini has been having issues.
Safari won't connect to internet, but Firefox does.
Time and date are frozen. Only resets when copmuter is re-booted.
Unable to update via App Store and iTunes won't connect either.
Please advise.

Hi again,
Let me ask for some better help for you that is familiar with this problem (if in fact it is a similar problem with the IP address and your ISP.
The other topic concerning this can be found at:
http://discussions.apple.com/thread.jspa?threadID=2725608
It is a somewhat lengthy thread but may just apply to your situation.
Anyways I will see if I can call on some better help for you. Hang in there. Best to arm yourself with enough info before contacting Comcast so they might know what you are dealing with fully.
littleshouders
edit: I have posted for some extra help for you that may have a better idea of what's going on if it is your ISP and their modem and how it handles the IP address causing Safari and iTunes not to connect. Hang in there it may take awhile but I'm sure someone will pop in to help.

My iPod and iPhone are connected by the same Apple ID and I've forgotten my pass code to my iPod, is there anyway I can get into it without having to delete anything?

I really need to find a way to get into my iPod without having to delete anything. (Note: my home button and power button don't work and I haven't synced anything at all)

No. You have to restore and thus erase the iPod. You have to options:
- If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone and use Remote Wipe to erase the contents of your device. If you have been using iCloud to back up, you may be able to restore the most recent backup to reset the passcode after the device has been erased.
You can also wipe the iOS device by installing the FindMyiPhone app on another iOS device and using that app to wipe the device.
- Place the iPod in recovery mode using one of these programs and then restore via iTunes:
For PC
RecBoot: Easy Way to Put iPhone into Recovery Mode
or
http://joshuabailey1997.wordpress.com/2010/09/02/recboot-v1-3/
If necessary:
Download QTMLClient.dll & iTunesMobileDevice.dll for RecBoot
and
RecBoot tip
RecBoot may have problems on 64X windows, then try:
Tenorshare ReiBoot – Enter & Exit iPhone, iPad, iPod Recovery Mode with a Single Click
For MAC or PC
The Firmware Umbrella - TinyUmbrella
Installs blootware on PC too
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

HT4910 I have 5 apple devices that are using the cloud. Do i need to have ALL of the devices backing up to the cloud since they are all on the same USER LOGIN or do i just need to buy more space?

I have multiple aple devices ( Ipad2, Ipad3, Iphone 4, Iphone 4s, Mac Mini, and Apple TV) I am using the same apple login to sync to the cloud. My question is do I need to sync ALL of them to the cloud or just one of the devices since I have them set up to sync anyway, or do i just need to buy more cloud space. Thanks

Welcome to the Apple Community.
You should sync all of them, if you want them all to share the same information.
Syncing is not the same as backing up. I suggest you continue to back up your mobile devices to your computer, unless you have a good reason to do otherwise.

I bought an apple store gift card by mistake is there any way for me to use that gift card money to buy an iTunes gift card?

Please help me guys I am so worried

You can't from Apple, they don't let you buy iTunes gift cards with an Apple Store gift card. You could see if a different store in your country might let you (though they possibly won't), or try selling the card to somebody e.g. family, friend, eBay etc

Is there any solution for windows 7 to avoid focus stealing problem as some background running applications are stealing focus from current windows.

To reproduce the focus stealing you can follow these steps
1. Go to following link and click on 'Try it'
2. Before the popup is displayed from the above page switch to another application like notepad and start typing.
3. When popup is displayed in #1 your keyboard focus should remain in the notepad.
we have some other java applications which are stealing the focus from current work and creating this disturbance.
Could you please let us know if there is any solution or work around to solve this issue.
Thanks,

Hi,
I think this issue is focused on java application development or software which supports the development, while this forum is mainly discussing issue about Windows 7 performance rather than development issues， I suggest you contact support in this forum,
thanks for your support

hi, sometimes big images could not open with photoshop.ı can open with windows but cant open photoshop.if ı try to open i am seeing a white image.is there any answer for this problem please.

Just to assist those who might help you with this, please give the exact version of Photoshop CS6 you are running, for instance CS6 13.0.1.3.
I had already asked for that in my previous post, but I guess you didn't quite know what I was referencing when I typed "exact version".
Sorry, I cannot help you myself because I don't deal with that kind of 3D images, don't use Windows, and in all frankness I'm not quite following your last post.
Also please give the exact model of your graphics card, so they can check whether it is on the list of cards tested by Adobe.
Thank you.

Is there any soft for IPHONE RING?

IS THERE ANY SOFT FOR IPHONE RING ,WHICH CAN RING AT RANDOM? Just LIKE NOKIA SYDYEM ,WHEN CALL COMING ,THE PHONE WILL RING AT RANDOM.TKS.

Sorry I don't fully understand your question but...
1. Turn off your caps lock - in a forum, it's the equivalent of yelling/screaming.
2. Turn your ringer up/down with the buttons on the side.
3. Put the phone on vibrate with the switch on the side.
If your phone is not working right, try resetting then restoring as per the manual. The English version is here... http://manuals.info.apple.com/enUS/iPhone_UserGuide.pdf

Help help help help. I just mistakenly deleted a Note from the Note App that I need. I don't use iCloud. The only place I have the Note app is on my iPad and my iPod. What can I do? Is there any help for this?

Help help help.
I just deleted a note from the Notes App form my ipad3. I don't use iCloud. The only place this note was is my iPod and iPad. Is there any possible way to recover this note?????
Thanks in advance

Thank you sberman, yes the first thing I did was check my iPod. Instant synching works great between the iPad and iPod, so it was deleted there as well. On both devices I have my Notes account to the same account.
I ashamedly have not synched to iTunes for ages. After I calmed down I realized that most of the info on that deleted Note I had copied and pasted from an excel file in November. I'm in the process of doing that again, and am only out the recent info.

My iPod Touch 4G just shut off one day while i was using tap to post. tried everything and nothing is working not even iTunes! Is there any hope for me? my iPod is my LIFE!!!!!!!!!!!!!!!! oh by the way none of this happened until i updated to iOS 6.

I have not had any experience in getting any devices repaired so I'm not sure which store to resort to. An official Apple store should more than likely get you what you need, but I'm guessing it's probably more expensive. (if any cost for your situation)
I hope you get your problem resolved.
