This is a technical question out of pure curiosity. I could probably dig through the documentation, but that would probably take longer than my curiosity would hold out, so I figured "why not ask?"
I occasionally switch between wireless (g) and wired (gigabit) networking with my home laptop on occasions when I want the extra speed for accessing large files. I'd noted before that this was pretty transparent, but for the heck of it I did a test today:
Connected to my home server (10.4's built-in AFP sharing, gigabit to a new Airport hub) using wireless, and started playing a medium-bandwidth (1.5Mbit/s) video file. With it playing, I connected the hardwired Ethernet, waited a bit for it to get an IP address, then tuned off the Airport card. I was honestly surprised that the video didn't even stop playing (and not due to caching), so obviously the transition was transparent enough to the app that it didn't stall out long enough to mess up the video. Switching back worked as well--in fact, I could tell it was changing, because via wireless there were slight glitches in playback, I'm assuming due to the way the player (mis-)handled preloading on a relatively slow connection.
Which got me wondering: How exactly does OSX prioritize network traffic when there are two available paths? All to the faster one, some connections prioritized over others based on hardware, or does it spread traffic around?
Also, given two alternate paths to the internet, what kind (if any) of load-sharing will the OS do by default? I'd always assumed that you'd need a special router to combine two separate internet connections (say, cable and DSL), but this got me wondering if OSX (given two network paths) would do some of this load-sharing by itself. I of course don't have two internet connections in the same place to try this with.
This is my sis's Mac mini, running the latest Lion OS and latest iTunes version 10.6.1 Her mac mini is on our home Airport Wireless Network.
Whenever she launch iTunes, she gets this pop-up message:
Do you want the application "iTunes.app" to accept incoming nework connections Deny and Allow buttons. Every single time have to click 'Allow' to continue.
Check the Firewall settings, it's on. Inside Advance Settings the iTunes allow all incoming connections. This is not really annoying and disturbing, but have to allow almost every day when iTunes is launched. The other way is to disable Firewall.

In our house we have 4 macs...two of them are new and I set them up by restoring from TimeMachine rather than with the migration tool as I have done in the past. This was recommended to me as a "cleaner" way to set up new machines (at least on an alternating basis).
On these two new machines I get a popup "Do you the application "microsoft word.app" to accept incoming network connections (this is also for excel or any office product). I'm still using Office for Mac 2008.
The only way I can find to stop these annoying popups is to turn off the fire wall, which I do not want to do (and which I have not done on the 2 mac books and they work fine).
Is there some setting or script I can run to fix this?
When I quit Word:mac 2008, I always get an error message that reads:"A file error has occurred. Check your network connections or make sure the disk is properly inserted and not defective.I have repaired permissions, rebooted, and did everything I could think of to fix this without any luck.
I have someone monitoring my outgoing internet connections. That person sends pings, knows my logs and IP addresses I connect with, Skype is of his highest interest. Is there any way to protect myself from people monitoring what I do and what websites I visit? Or at least to know WHEN I am being watched? Is Network Utility of any help?
Is so, how to interpret it? I don't know much about MacBook, I was a Windows person till July. I had Tor, Privoxy and NetShield installed but it's a bit fussy and slows the connection. I have a MacBook with Intel 2.1 GHz processor, Leopard 10.5.6 OS and Safari 4 beta (552816). I use a wireless internet connection via a USB modem (Huawei E220). That person uses a PC with Windows XP.
I have several home security cameras that utilize Java.I've had them for years. But just in the past day, I've begun noticing a lightning fast popup that comes flying by and leaves so fast I can't even read it. It happens when I first launch one of the cameras in either Safari or Firefox (likely would do the same in other browsers too. I finally had to use a screen recording app to be able to record when the pop up flies by.I then slowly scrolled and paused on the message.It is a standard security message that says, "Do you want the application "Java" to accept incoming network connections?"
There is an ALLOW and DENY button but there's no way the popup ever is on the screen long enough for you to even read it, let alone click on a selection. I see lots of other posts about this around the discussion forum and I see how I could go into the Security preferences and perhaps allow network connections there, assuming I can figure out how to point to the correct piece of Java code (System/Library/Java/JavaVirtualMachines/1.6.0.jdk???) But my bigger question is why now? I haven't done any updates in the recent past and I log onto to these cameras every day... Granted this popup goes by fast but it is noticeable... Had it been there a week ago I would have noticed it... But no... It just started today. Why? And why would any message that seeks a user choice automatically appear and then disappear within a fraction of a second?
I have (had) an effective VPN connection established on my iMac to enable connection to my work computer. I recently reviewed my use of users, creating a separate administer account and changing my home account privileges from admin to 'standard'.
I am now unable to use the VPN connection from my home account. The connection shows in the Network pane but the "Connect" button is greyed out. If I unlock the Network pane using the administrator details the Connect button becomes operational.If I change to the administrator account I can use the connection fine.
How can I enable the use of the VPN connection from a standard user, having locked the network connections (for the sake of not having children interfere with the network settings)?

I get this Accept or Deny message every time I open iTunes. I realize I have Firewall enabled, but is there anyway to set itunes to accept automatically?
Because I have Firewall enabled, everytime that I launch iTunes, I get a popup asking me: "Do you want the application "iTunes.app" to accept incoming network connections?" I click on "Allow." But unlike other applications where this process is only asked once, the first time you launch an app, I'm asked this every time.
I've talked with AppleCare about this, and the representative told me it may be because I've disabled "Copy files to iTunes Media folder when adding to library," because I prefer to organize my music folders my own way. She offered 2 work arounds:
1) Enable file sharing of my Music folder. It didn't work. The prompt still occurs every launch.
2) Reinstall iTunes. However, admittedly, she said this may not necessarily resolve the issue as it could simply be because I'm not using iTunes' file location by enabling "Copy files to iTunes Media folder when adding to library."
Does anyone have any idea how to resolve this? Also, if I reinstall iTunes, will I have to re-add my Library to iTunes or are the relevant database/album covers files & folders retained?--it took a few hours for a collection of my size to be added.
Receive "Do you want the application "iscsid" to accept incoming network connections?" at every startup in OS X Mavericks 10.9.4. Have configured Firewall to Allow access (iscsid...Allow incoming connections) but still receive prompt. Only Support page that seemed somewhat related is URL.... Installation of Java also did not alleviate problem. No communication issues with Drobo Mini or Dashboard - just tired of receiving seemingly unnecessary modal prompt upon boot.

On startup I get a window that asks, Do you want the application "Service" to accept incoming network applications. I can't get rid of it nor can I discover its source.
Is there anyway to have System Preferences create network "profiles" that save more than just the name of the network and the password, but also the "advanced" settings specified by the user. At home, the IP address, subnet mask, etc. need to be entered manually, but everywhere else, I need to use DHCP to connect to networks, which clears my settings. It is getting very annoying having to re-enter these settings every day.
The picture worth a thousand words is at the bottom of this post.Looking for Airport configuration advice as I modify my home network. Everything is at latest firmware versions. 1. Broadband Source - Comcast Cable. 2. Broadband Modem - Motorola SB5101, configured and working as router. ISP doesn't allow it to bridge.3. Two Airport Extreme's... early "n" MA073LL/A and brand new MB763LL/A.4. One Express, need it for Airtunes.5. HP printer with Ethernet.6. USB hard drive.7. Six g clients, three n clients as shown.8. No coverage constraints (small house, thin walls).9. One Airport Extreme, the HD, the printer and the Express must be in a certain location.10. Incoming cable, cable modem, one Airport Extreme must be 25' away from #9.
I have a new macbook pro i5, and the question is if it is possible to change the configuration of what programs will use the nvidia gpu. This is, because I have some writing program that really dont need the nvidia gpu, and the mac use it innecesarily.
I just started my macbook air first time and I wrongly selected another keyboard instead of US during the auto configuration...how to go back and set the US keyboard layout?
I'm looking for a solution to my WiFi internet connection.I haven't used my MacBook Pro laptop in the last week or so - which means there is no way I have done any changes to the network configuration. However when I now try to connect to the internet via a Hub - which is previously set up on the macbook and worked no problem - is now not working at all.

I need to change the display configuration of my macbook but I can't see to open the preferences (because the configuration is wrong!) - what can I do?
I have a mixed Mac/PC environment - Macbook Pro (snow leopard); iMac 21 (leopard); 2 x Dell laptops (XP) - and an existing wifi network from a Belkin 8233-4 N modem/router. Also connected to the wifi network is a WHS for backing up the laptops; an HP printer; 2 iphones; an xbox 360; and a Wii.
I've just bought a 1TB Time Capsule to use to back up the Macs as my previous external time machine hard drive just died (which was connected via USB to the iMac).
At the moment, I've got the TC set up to join my existing wifi network (it's connected via an Ethernet cable from the Belkin wireless router), however I'm getting issues with the wifi network not working properly and being unable to connect to the internet. Every time you wake the Mac, you have to manually reconnect to the wifi (and sometimes even re-enter the password), and things work OK until the Mac goes back to sleep. When I go into the Airport utility, the settings say that the TC is set to create a new network, so I reset it back to join an existing network via ethernet, but then if I go back to these settings a little later (after having problems with the wifi connectivity), they have reverted back to create a new network !
I have a couple of movies here and i just converted them on .mp4 so i could be able to watch them on my ps3. the movies on my mackbook pro look fantastic, almost like HD! but when i converted them doesn't look as good. I guess i need to change the configuration. How should i put it so the quality wont change THAT much?
Since upgrading to iTunes 10.5.2, I have problems using airplay to connect to my hi-fi speakers.When I enable them in iTunes I get the message "Do you want the application "iTunes.app" to accept incoming network connections? " immediately followed the message."An error occurred while connecting to the AirPlay device "hi-fi". The network connection failed".If I choose "allow" for the first message, deselect "hi-fi" in iTunes and select it again, it works!This is becoming more annoying having to do this every single time.I am using an Airport Xpress with airport utility 5.5.3 and Mac OS 10.6.8

I'm trying to decide on a NAS and have narrowed it down to two, QNAP TS-419P vs Synology DS410.
Basically I'll be using this as a file backup and media server. I am thinking I will set it up as a RAID 5 with 2TB disks. I am especially interested in using it as a centralized video server for my PS3.
When I convert a MS Word document (MS Word 2004 for Mac) to a PDF document, using Adobe Acrobat (v. 8 for Mac), the hyperlinks that were inserted into the Word document are not present in the PDF document (hyperlink text is present, but it is not clickable or colored/underlined as it was in orig. Word document).
Please inform me of any setting in Acrobat or Word that I may need to change to get the hyperlinks to carry over properly during conversion. I really don't want to go through all of my PDFs that I have created and re-insert hyperlinks manually, as there are TONS of them..!
Currently I keep my time machine backup on an external usb hard drive which is a seagate hd in an enclosure I bought a while ago. I want to maintain a second copy of the time machine back up.
Is it better to buy an external RAID enclosure, put the current drive in there, get another drive, and then just have time machine backup to that drive?
Or should I just get another enclosure and another drive? If I do it this way, can I automate the time machine backups across two drives in any way, or I have to manually run it twice?
Any way I can encode video on my 13" 2011 MBP without maintaining a CPU temp of 92 degrees? Ideally I would use iVI with some sort of CPU limit but that route seems pretty dodgy so is there any lightweight encoding software that I can keep running all night without worrying about wearing out my precious mac?

PlI plug in my iPhone to my Mac to sync. While in iTunes, I select my iPhone in the side bar and then I select Apps. Once in Apps, I organize my apps into tidy folders. For example, I put all of my airline apps into the same "Travel" folder. I do this to prevent having pages and pages of apps. After doing that, I press the "Sync" button to save the changes to the iPhone. The changes seem to stick. No problem.
I look on my iPhone and the changes are made. I unplug my iPhone and the changes are still there. However, when I plug in my iPhone to sync the following day, all of the apps are unorganized again. This has happened repeatedly for weeks. Not sure why. Some previous organizational changes I've made are OK. It seems the iPhone simply will not allow me to organize the last 7-10 apps I've added to my phone.
