Why does my mac mini server keep dropping off the network?

I have Verizon FiOS and use its router/wireless to connect all macbooks, macbook pros, etc. connect to each other and the snow leopard server, which runs the printers and time machine for one of the laptops. I'm not using any other heavy duty server apps. I just want the mac mini to stay on the network and do its job. Invariably when I go down stairs to the mac mini and ethernet to the router to share screen, I find some update that needs to be installed, which apparently is why the mac mini has gone on strike. I usually can see the problem when I go to connect to server and see the other macbooks, but not the mac mini. Then after much coaxing, I'm able to get the server back on line for a few days, until the next software update. The server is set to auto restart, but why is it balking at rejoining the network?
mac mini is running snow leopard, as are three of the four macbooks. router is an actiontec model. wireless network is WPA2 and mac mini is ethernet connected to the router.

I've just experienced this problem when using a Marantz SR4001 receiver between my Mac Mini and HD TV. I noticed that the problem didn't happen all the time and I have found a workaround solution.
The problem is not a fault, but seems to be caused by the receiver defaulting the HDMI video properties. It's an old unit so I'm thinking that 720p is a default resolution for the receiver.
I can make the problem happen if the receiver is turned on before the TV. Seems that without an output connection the receiver is telling the mac that it expects 720p.
If I turn on the TV before the receiver, the TV seems to tell the receiver that it is expecting 1080p 25fps and the receiver obliges and the Mac retains those display properties.
So it appears that the video output device dictates the output properties back to the receiver and the receiver in turn back to the Mac. In absence of an output device the receiver defaults to 720p.
Solution: Turn on the TV before the receiver.

Why does my mac mini wifi connection drop off?

After an idle period my WiFi connection on the Mac Mini drops off and needs to be clicked on & modem selected to connect back on.
No other devices on the network are affected in this way. iPhones, PC's, iPad, & android tablets have no problems staying connected.

Could be due to interference

Why does my generation 1 ipad keep dropping off

Why does my ipad keep dropping off. It is generation 1.

Dropping of of what - wifi? When you ask a question you need to provide enough info to get an answer.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Why does my Mac Mail programme keep turning on the SSL option?

For a couple of years now my wife's Mac Mail programme has from time to time stopped getting most of the emails sent to it for a week or more. I've wasted many hours on the phone to our service provider without ever getting to the bottom of the problem. Now I believe I know what's been happening. It seems that her Mail preferences keep turning on the SSL option without any human involvement. Apparently emails sent to an SSL selected email address will only make it into her in-box if they come from an SSL selected mail programme. Yesterday, scratching my head as to why, once again, few emails were getting through, I once again looked at the preferences and noticed that the SSL option, which I had recently unchecked, was once again checked. I unchecked it. It immediately re-checked itself. I unchecked it. It immediately re-checked itself. And so on, for ten minutes when, suddenly, it remained unchecked.
Why is this happening? My wife never, and I mean never fiddles with settings on her computer and nobody else uses it. The checking of the SSL option is being done entirely at the behest of the machine itself. Can anybody tell me how this could be happening? And could anybody tell me how I can stop it from happening again?

Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -Rh $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Step 1 should give you usable permissions in your home folder. This step will restore special attributes set by OS X on some user folders to protect them from unintended deletion or renaming. You can skip this step if you don't consider that protection to be necessary, and if everything is working as expected after step 1.
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Why does My Mac Book Pro Keeps Shutting Off During Boot Up.

You can download music purchased from iTunes again for free, in case it is lost.

Why does my Mac Mini running on Mavericks so slow to start and load apps?

Why does my Mac Mini running on Mavericks take so long to start and load apps?

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal 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. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

Why does my Mac Book pro keep restarting

why does my Mac Book pro keep restarting and how can it be fixed

It would be nice if you could include a kernel panic log to verify that your problem is...
Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):
         com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff
            dependency: com.apple.NVDAResman(6.4.0)@0x834a0000
            dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000
            dependency: com.apple.iokit.IOPCIFamily(2.6.5)@0x7a802000
            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
         com.apple.nvidia.nv50hal(6.4.0)@0x83c05000->0x84019fff
            dependency: com.apple.NVDAResman(6.4.0)@0x834a0000
         com.apple.NVDAResman(6.4.0)@0x834a0000->0x8378dfff
            dependency: com.apple.iokit.IOPCIFamily(2.6.5)@0x7a802000
            dependency: com.apple.iokit.IONDRVSupport(2.2.1)@0x82fd3000
            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. The unfortunate thing is that many people have passed the “three years from date of purchase” now and Apple is not honoring the free logic board replacement for many users. Some dealers seem to be making some exceptions for those past the three year mark, but don’t count on it…
Good luck,
Clinton

1 of 3 macs in home keep droping off AE network

Have had my 3 macs and airport extreme network working fine for 2 years. Now one of the 3 is starting to drop off the network and does not always respond to my password to re-access. Very slow internet when it is on the network. Works fine off my neighbors unprotected network.
No change in range and my macbook works fine sitting next to the troubled imac so no range problem. Also, iPad wifi is fine throughout the house
Any ideas??

That's plenty strong enough. Another explanation for what you're experiencing is noise. To see the noise level that Mac is experiencing, nn your Mac pull down the Apple menu and select "About This Mac". In the resulting window click on "More Info". In the resulting window select "AirPort" under the "Network" category. On the right under the name of your wireless network you'll see to the values to the right of "Signal / Noise"? In a "quiet" environment a typical noise level is in the -90s.
To compare the signal and noise on that Mac with what the other Macs are seeing, you can use the advice in the second message of this thread.
There's one other thing you can try. It might help to reset the connection settings on your Mac using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease". Note that the fix this step implements may be temporary.
6) In the folder /Library/Preferences ( _not_ <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
These steps may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

Officejet 4620 drops off the network after the first operation

HP 4620 drops off the network soon after one operation is performed. I have to turn it off and on again to bring it on line and then it repeats. The message is " unable to communicate with printer". I have run all the diognostics and they say your printer is operating normally. I have down loaded the latest drivers. Running Win 7 (64 bit). My only clue is that I have a new router, Netgear.

Hi LennieZup
I understand you can print over the network one time and then you have to turn the printer off and on again to continue to print.
I will be happy to assist you with this.
It may not be the printer, it may be your router's inability to wake the printer.
Disconnect the power cable on the router for 10 seconds, then reconnect the power cable again. You might need to check to see how many devices can be setup on the router at the same time. Depending on each router.
I would recommend updating the printers firmware. HP Officejet Firmware.
I have included a document for Printer Does Not Maintain Wireless Connection. Try Step six: Assign your HP product a static IP address.
If you need more assistance just let me know.
