External device usage?

I've never tried using any external devices (aside from Mighty Mouse) with my laptop. Is it possible to use the MBP with the cover closed, essentially using it as a CPU with a wireless keyboard, wireless mouse, and external display?

RAM issues when plugging in external devices

When I plug external devices in such as a USB drive, iPhone or a Firewire external HDD the RAM usage on my Mac shoots up beyond normal levels. This has only started happening recently.
Say for example I plug in my iPhone to sync it. With only iTunes running (no other programs in the dock at all), I get the force quit box come up asking me to close programs down because it doesn't have enough RAM.
I don't get the force quit box come up when I plug USB devices in but the Mac still becomes nearly unusable.
Any ideas how to reset or fix this RAM problem (or whatever else it might be)? Everything else is fine, I can numerous programs that require lots of RAM with no problem at all.

Try resetting the PRAM and resetting the Systems Management Controller.
PRAM
1. (Re)start and immediately press & hold the CommandOption+PR keys
2. Listen for two startup chimes.
3. Release all keys and let the Mac start normally.
SMC
1. Shut down the Mac and disconnect all attached cables; power, USB, FireWire, Ethernet, etc.
2. WAit 15 seconds.
3. Reattach the power cable and a USB keyboard & mouse.
4. Restart the Mac.
5. Reattach all hot attachable peripherals.

My Apple Macbook Pro running OS X Yosemite freezes 10.10.1 regularly. When it freezes the only remedy is to physical shut the screen. I don't use any external devices.

My Apple Macbook Pro running OS X Yosemite freezes 10.10.1 regularly. When it freezes the only remedy is to physical shut the screen and wait for the battery to run down. I do not run any external devices, and when it freezes you cannot do anything with the computer. It is new, and this problem is very frustrating. Any suggestions?
Thanks

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Select the BOOT_TIME log message that corresponds to the last boot time when you had the problem. Now clear the search box to reveal all messages. Select the ones logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Some private information, such as your name, may appear in the log. Anonymize before posting.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". A shutdown stall report has a name that ends in ".shutdownstall". Select the most recent of each, if any. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot. It's possible that none of these reports exists.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

Unable to locate external device after upgrade

i have been using FCE 2.0.3 and mac os 10.3 to view clips on video monitor (tv) easy set up was dv pal. so i chose view and and then firewire from the FCE menu to review clips on video monitor through my cannon mv750i-worked ok until recently. I have also been able to capture as well. Nothing wrong with the camera as it works ok in another computer (power pc) which has mac os 10.4.7 but fce is still 2.0.3. So is something i am not doing?
i then upgraded to mac os 10.4 and fce to 3.5 and easy set up also at same dv pal and a window message comes up informing me that "unable to locate external device" or you have changed system configurations. I have made sure that the camera is on. so please can someone tell me what i can do?

When I recently upgraded from OSX 10.3.9 to OSX 10.4.7 I found that FCE 3.0 would not recognise the camera.
When I upgraded to QuickTime 7.1.2 the problem immediately disappeared.

Satellite P200-1EE: HD-DVD issue: Unable to output video to external device

I know this subject has been brought up before but after searching the web on and off for months now I still can't find a solution that works for me.
The problem occurs when trying to use the Toshiba HD-DVD Player to play HD-DVD discs. The program starts but after reading the disc it displays the message +"Unable to output the video to an external device. Please check the external output setting after ending the application."+ and will not play the movie. I'm not sure when this problem first started happening as I went a couple of months without using the HD-DVD feature but I know my laptop was capable of playing the DVD's on both the laptop's display and through the HDMI cable when I first got it just under a year ago.
Toshiba's website mentions this problem and suggests updating the Realtek Audio drivers but I've updated several times now and there has been no change. I've also updated the HD-DVD Player software, also to no avail. The problem is the same regardless of how I try to output the video and occurs on any HD-DVD disc.
I've read that PowerDVD may be a better choice for playing HD-DVD's but I'm rather reluctant to spend the money when it might not work so unless someone can guarantee this as a solution I don't think I'll be trying it.
If anyone could suggest a solution that I haven't yet tried I'd be very grateful.

>The program starts but after reading the disc it displays the message "Unable to output the video to an external device. Please check the external output setting after ending the application." and will not play the movie.

I am having one application which i am going to install on my ipad and i am having one external device having USB interface. I want to have communication in between my device and ipad over USB/BT. is it possible

My external device is having male USB connector. The cable available in market are having can be plugged to the device having female connector.I will need converter in between as my device is having male connector. Can i get such cable? If yes can i establish communication in between my app and device over these cables.I am not passing any audio/video data or photos.I am sending data frames. My device is having firmware and it sends data frames in firmware understandable format. Let me know can i have two way communication in between over USB/BT?
Right now i am connecting my device with host PC and i want to replace my host PC with ipad.

Thanks....
will it be possible to establish communication in between my device and app. Because camera conection kit only transfers photos and videos and my device doesnt have any audio/video data.
If yes, should i add photo header to my frames and will send as corrupted photo file or what needs to implement so that i can have sound communication in between.

How to make external devices (like iPods, etc.) NOT mount as connected drives when plugged in via USB to a Mac?

If I plug my iPod (or a thumb drive or whatever) to my Mac's USB port, the device appears as a icon representing a connected drive on my Mac's Desktop.
This is normal, expected behavior.
HOWEVER, in some cases, I'd prefer that the device not "mount" as a connected external drive.
With thumb drives or external USB drive, of course, I want them to "mount" so I can transfer files on or off them -- that would be the only possible reason to connect an external drive like that.
But with other Apple devices like iPods or iPhones, there are TWO possible reasons to connect them to a Mac: either to "sync" them or transfer files on/off them; OR, to simply recharge the device's battery. (Or, both sync and recharging functions at once.)
For those people who use their Apple devices in ways that require transferring files (i.e. most people), then having the device "mount" as a connected device is a desirable behavior.
But in my circumstance (and I bet there are a lot of people in a similar circumstance), I have no need or desire to transfer any data to or from my device every time I plug it into my Mac: I'm plugging it in SOLELY to recharge the device's battery.
Specifically, in my case, I have a 6th-gen iPod Nano, and I use it exclusively as an FM radio and a pedometer. I don't have any mp3s or songs or any other external files loaded on it, nor do I plan to add any in the future.
The only reason I ever plug it into my Mac is so that I can recharge the iPod's battery.
But the "problem," which is a minor one I admit but a problem nonetheless, is that every time I connect the iPod to the Mac, the iPod appears as a "connected drive" icon on my Mac's desktop. Which means that I'm not supposed to just unplug the iPod when I'm done -- first, I have to find its icon on the Mac Desktop, and then drag the icon to the Trash, to "unmount" it -- and only then can I freely unplug the iPod without getting an error message telling me that I shouldn't just disconnect connected drives without first properly unmounting them.
This would be bothersome enough if I only had to do it once per connection, but in the case of the iPod Nano, there's no way to tell how recharged it is while it is in the act of recharging, so that to see if I'm "done," I have to unplug it, check the battery status, and if it's not fully charged, re-plug it back in. So that each time I recharge it, I often have to unmount the drive several times, depending on how impatient I am.
There has to be a way to prevent the mounting of the drives of devices that one is connecting simply for the purpose of recharging. But how?
Strangely, I also have an old iPhone, and when I plug that in for recharging in the same way, it DOESN'T appear as a connected drive on the Desktop. I'm not sure how I managed to do this, but long ago I must have changed some setting or preference for this to happen. And by now I've forgotten what I did.
I'd prefer that I could change the "mount/don't-mount" setting on a device-by-device basis -- i.e. make it such that this particular iPod doesn't load, but perhaps a different iPod would load -- but if that's not possible, then is there a way to stop ALL iPods and iPhones from loading as connected drives when plugged in?
(I'm not talking about appearing as connected drives within iTunes -- I'm talking about appearing as an icon on the Desktop in the Finder.)
And please don't tell me to just buy a wall charger! I prefer to recharge off my computer if possible, using the charging cord that came with the iPod.
I presume there's some simple setting to toggle this on or off, but I haven't yet found it. Any clues would be appreciated. Thanks!

Well, I already know about that Finder Preferences option, but that is not what I'm looking for. Why not? Because I still need CDs and DVDs to appear on the Desktop and mount properly! If I uncheck the "CDs, DVDs and iPods" option, then I lose the ability to access CDs and DVDs, which creates a whole new problem for me. What I want is to not mount iPods only -- actually, what I really want is to not mount this particular iPod -- but if that level of specificity is not possible, then I want to exclude just iPods from mounting, without also condemning CDs and DVDs (or whatever) to invisibility.
Also, I was confused by the way the Preference is worded: It says "Show these items on the Desktop," with a series of options to check. But this phraseology seems to mean that the unchecked items will still "mount," they simply won't appear as Desktop icons. One would still have to "Eject" them using a menu command, rather than dragging the icon to the Trash -- right? Or am I mistaken, and is the Preference Pane simply badly worded, and when they say "Show these items on the Desktop," what they really mean is "mount these external devices as connected drives." So that if a category is unchecked, then they won't load as external drives at all?
But if so, then what purpose could possibly be served by inserting a CD or DVD that is not recognized by the computer? And if it isn't recognized, then it would seem that there would be no way to ever Eject the CD or DVD disk. Right?
Thus, if I uncheck that Finder Preference box you suggest, one of two outcomes will result:
-- Either CD, DVDs and iPods are still mounted, they just won't appear as icons on the Desktop; but they would still need to be Ejected via a menu command, which doesn't solve my problem.
-- Or, CDs, DVDs and iPods are not mounted or recognized by the computer at all, which means that if I insert a disk into the disk drive, it will get stuck there forever, since there's no way to Eject it, since the OS doesn't recognize that it's even there. Which is thereby a new problem.
Either way, I'd have a problem! Or...? Clarification, anyone?

Is there any way to see if a file has been saved to an external device, or to see a history of which external devics have been connected to an iMac in 10.6.7?

I have a client that believes someone came into his house and took some digital files (photos, stored in iPhoto) off of his iMac (2.66GHz running v10.6.7)
He usually just sleeps his computer while away and requires no password to login. Is there any way to see if an external device or CD/DVD has been used to save files? Is there any wya to see the history of a file and determine if it has been saved anywhere else? I know this is a long shot, but I figure it is worth asking.

Will it continue to say that the device is in lost mode if it has been restored? My Find Iphone is saying that when the device is connected to the internet that it will be locked and that a message (that I typed in) will appear. It also says that I will be notified and that a sound will occur when it is connected. Now my iphone has been updated to the ios7, but I don't think his ipod was updated.

Java 6 you can't as Apple maintains it, and Java 7 you could if you uninstall it and Oracle provides the earlier version which they likely won't his last update fixed 37 remote exploits.
Java broken some software here and there, all you'll have to do is wait for a update from the other parties.

Error while trying to synchronize audio and MIDI. Sample rate 42804 recognized. Check conflict between Garageband and external device.

Sometimes, while playing back my software instrument songs, I get an intermittent pop-up error message, saying "Error while trying to synchronize audio and MIDI. Sample rate 42804 recognized. Check conflict between Garageband and external device."
(Sometimes the five digit number is different, but remains a five-digit number beginning with "4".)
Simultaneously, the song stops until I press the "Okay" button in the pop-up window.
When I continue to play the song, the sound is jerky and clipped, and the playhead doesn't keep up with the song, and then suddenly jumps to the part of the song currently being played.
There's also a sound of static.
The issue seems to occur whether or not I have my MIDI controller turned on and plugged into my desktop Imac.

Hello,
open your Audio MIDI Setup utility and set the input to 44100

No audio out on internal speakers or headphones from external device

I'm using an intel iMac 17" I tried to plug in an external cassette deck, and listen to it through the internal speakers. Even though all system prefs for audio work as expected, and I can see the audio meters on screen operating, nothing will induce it to play sound either through the internal speakers, or headphones.
The audio is certainly going in there, as it recorded perfectly in iMovie. The internal speakers work perfectly for alerts, iTunes, the web, everything. But no external device will work.
I've tried an iPod, a microphone, and a cassette deck, all with the same result. I've launched Garage Band as this can upset the midi player, but it's fine. I've visually checked the settings, no problem.
As an alternative I also tried an iMic and stopped using the jack input on the iMac. Still nothing. I plugged headphones into the iMic, nothing. No audio will play unless it's already on the Mac. External audio goes in there and dies before it reaches the speakers.
All the visual info I get in the sound panel regarding connection options, output etc, is exactly as expected, I just can't get any audio at all.
Does anyone have any suggestions? There's only a few day's warranty left...
Many thanks.

Hello David,
Thanks for the pointer. I looked at the website for Linein, and I already have Audio Hijack pro installed, which contains this application. When I ask AH to record the system audio, the volume meters are dead, I hear nothing, and record nothing - unlike iMovie.
When I do ask it to record, I can hear a thumping sound from the Mac speakers, but nothing else.
I'm really desperate for a solution to this; I can't understand why it's so hard to achieve. If it was just the line in socket I'd suspect that, but a USB connection as well? I don't understand that at all.

Unable to copy hard drive on to external device from Disk Utility. Getting error message "cannot allocate memory".

I am trying to retrieve the information on my hard drive after I spilled liquid on my keyboard . I can get to Disk Utility by using the boot up disk but when I try and copy the hard drive to an external device using "New Image" it tells me it is unable to create a copy because it "cannot allocate memory".

Were you able to get any help with this problem? My MacBook Pro out of the blue wouldn't boot up all the way and now I'm trying to get a copy of everything onto the new external drive using disc utility but am having the same errors as you! Thank you for sharing any tips!! -Norah

What's the easiest way to add storage to a mac mini. (1TB hard drive but only 32G of real storage). External device, internal or partitioning?

What's the easiest way to add storage to a mac mini. (1TB hard drive but only 32G of real storage). External device, internal or is there some way to partition? I tried doing so but received a message that there wasn't enough free space to partition. Seems like a 1TB drive should have more storage than my Ipad

Its worth confirming what free space you have on your drive:
go to: Apple Menu > About this Mac > More Info > Storage
The bar chart shows how much free space there is on the drive:
Please realise that partitioning does not create extra space so this wont help you.
If your free space is less than 20 % you should get extra storage with an external USB or Firewire drive, any make or model will work.
