How can I see what apps are running on a non-startup disk

I recently changed over to a larger drive from my older startup drive. I want to erase that original drive and clean it up. When I go to Disk Utility and erase it says "erase failed, could not unmount disk". I try to eject it and it says "HD is in use".
I figure I just need to see what's running on that drive and stop it somehow, or if there is another workaround?

If you're willing to use a command in Terminal, try this, where "old_disk" is the name of the old disk. (If the name of the old disk contains any spaces, prefix each space with a back-slash.) It will show you each file on the old disk that's open.
sudo lsof | grep /Volumes/old_disk
Spaces doubled for readability. The character just before "sof" is a lower-case letter "L". You'll be prompted for your administrative account's password.

How can I see what apps are running on my iphone 5?

Is there an app that will show me the apps running and also allow me to close apps that don't need to be running?

Double tap the Home button, this brings up the Multi-Tasking bar. Any app running in the backgroud will be listed. Tap & hold any app until they all start to wiggle. Tap the red minus sign to remove the app from the Multi-Tasking bar.
Note: very few apps are actually running in the background...they must be designed to do so. Almost all apps listed will not be running, but rather in their last used state.

How can I know what apps are running in the background of Q10

My battery is not lasting more than 12 hours even though I'm moderately using it. How can I tell which applications are running in the background?

As of now, the BB10 does not allow any apps to run in the background unless they are baked in the OS or in the active frames. So if an app is not in a active frame, no app is running in the background. try maximizing your battery by switching to wif whenever you have a wifi network.

How can I deternmine what apps are running on my Mac Book Pro

Hoe can I determine what applications I have open and running on my Mac Book Pro

1. Use Activity Monitor (it's in the Utilities folder, which is in Applications, or just type Shift-⌘-U in Finder)
2. Show the Dock and look for the "indicator lights".
If they are not there then go to System Preferences > Dock and select "show indicator lights for open applications"

I just got an IPAD2 on Saturday. With the Mac, I could always tell when programs were open/running by going to the menu bar. How can I tell what programs are running in the background. I am struggling with not being able to go to a menu bar at the top

You can see which apps are open and/or recently used by double-clicking the home button to bring up the taskbar at the bottom of the screen (not all apps that appear there are active) - you can then close apps on it by pressing and holding one of them for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Mail app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar. If you have an app 'open' on-screen then it won't appear on the taskbar, you will need to go back to the homescreen first, and it should then show when you next open the taskbar.

How do i see what applications are running in the background

My iMac is running very slow my operating system is OS X Yosemite Version 10.10.2 with a 2.5 GHz Intel Core i5 Processor. How do I see what applications are running in the background?

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Reinstalling OS X Without Erasing the Drive
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list. Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Alternatively, see:
Reinstall OS X Without Erasing the Drive
Choose the version you have installed now:
OS X Yosemite- Reinstall OS X
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless.

How can I see what photos are stored on iCloud?

How can I see what photos are stored on iCloud? I haven't used Photo Stream before so there are no photos on there that I can see.
Help needed ASAP.
Thanks

If you haven't used Photostream there won't be any photos "actually on iCloud".
Any photos stored as part of an iOS device backup can be viewed on the iOS device after restoring the backup to the iOS device. They can't be viewed online.

Any way to see what apps are running in IOS7?

To see what apps were running on my iPhone 4s with IOS 6 all I had to do was double click the main button. Now that I've upgraded, this action brings up a ribbon of all the apps I have. I'm trying to find out why my battery life has shortened considerable with IOS7.

You are not seeing a ribbon of all your apps. Just like under iOS 6, double tapping the Home button will show you your most recently used apps. Most of them are not actually running. Just like under iOS 6, force closing apps will, unless the app is misbehaving, have minimal effect on battery life.
There are some new features of iOS 7 that can result in increased battery use. See this article for some suggestions:

How can i see what devices are connected to my icloud?

I want to know if pictues from my mac are on any other devices. How can i see what other devices i have connected to my icloud?

My brother asked me for my account one day but i don't know if he used it to connect icloud or to just download an app. I just want to see if his device is connected to my icloud and if so, i want to disconnect him. So is there any site or anything i can do to see what devices are connected?

Colorblind users can't tell what apps are running

There needs to be a setting under Dock Preferences to CHANGE THE COLOR of the dot under running applications in the Dock.
I know the dot is there because I asked where the arrows went in the Apple Store and they told me it was there. After straining and squinting, I can almost see it. This is NOT ACCEPTABLE.
With my color blind situation, I can no longer tell what apps are running or not. I have to press command-option-escape for force quit just to see what is running.
Either bring back the Tiger black arrow, or allow a preference so that color blind users can tell what is going on.

You bring up an excellent point but no one at Apple who can make the change is likely reading Discussions. Put in a request for the Dock improvement at Apple OS X Feedback where it will be put in Apple's system for user requests.

Help!!! How can I see what devices are connected to my icloud

HT4528 I have an IPhone 4S--How do I see if apps are running in the background and should they be deleted?

I have an IPhone 4S. How do I see if there are any apps open in the background and if so, should they be deleted to save energy?
Thanks

Very few apps run in the background - mainly music playing apps and GPS apps. Double-clicking the Home button gives you a list of previously used apps, not (as so many people believe) "running" apps. You can delete the apps from the list if you wish, but it will make no difference to energy usage (unless they actually are running, as in the categories above. You should know if you are using GPS or if you can hear music).

How can I "see" what drivers are currently loaded in memory

I am currently trying to track down an "apparent" memory leak where the performance of my relatively idle Macbook degrades over time due to an ever increasing allocation of wired memory (as viewed from Activity Monitor). Within about two hours of rebooting with only the essential processes running, I see my wired memory continue to increase up to and beyond 700 MB. About this time I experience intermittent spikes in the "CPU-%System" allocation of 25% and more which causes severe lagging in my mouse and keyboard. The machine eventually becomes unusable and requires a reboot.
Because I see the wired memory continue to grow inexplicably over time and I am unable to isolate this to any processes listed in the Activity Monitor pane I have to believe that it is something not "visible" from the AM pane. I have read that wired memory is responsible for hosting the VM objects, the VM buffer caches, the I/O buffer caches, and the drivers.
FWIW, I downloaded "Main Menu" maintenance software from Santa Software and ran all of the cache maintenance scripts - unfortunately, this did not effect any discernible improvement.
My next guess is that there is some ill-performing driver loaded into memory that is chomping on my wired memory but I do not know how to "view" what drivers are currently resident.
Is there a way to view each of the drivers that are currently loaded in memory?
And, better yet, is there a way to view what amount of memory is currently allocated to each such driver?
Any help is much appreciated - thanks in advance!

You would certainly see SOME "depreciation in memory", due to e.g. spotlight indexing and other processes. But it should be nowhere near to what you describe to the point where your CPU fan runs.
Without any further detailed technical expertise, I would assume that it could be a RAM stick that is not working as it should be, resulting in the CPU having to make the extra "effort" to compensate for lack of RAM.
Have you taken the RAM sticks out and reseated them? An dust preventing good contact?
