.Mac address keeps disappearing

Hello,
I'm using 2 mail accounts on my iphone - one is my own domain via pop, the other is a .mac address. About once every other day the .mac address account completely disappears from my phone without me having touched the settings on either my phone or my computer.
Has this happened? Should I be unchecking something in iTunes to resolve this?
Thanks

Mac Mini keeps disappearing from network

I have a 2009 Mac Mini running 10.9.1 that is serving as a media center computer. Plex Media Server is on this machine along with my collection of movies and TV shows. I frequently access this machine using Plex clients, both on Mac and Roku, and also via file sharing and screen sharing on other macs. I almost always manage this machine through screen sharing, which makes this problem extremely frustrating.
Basically this mac keeps disappearing from my network. I can see it under "Shared" in finder on another computer, but when I click on it it hangs on "connecting" for a while and then just disappears. Same thing when trying to access via the Plex client on Roku. Sometimes I try to play something and it tells me to make sure my server is connected and running, and sometimes it doesn't even see my Plex media server at all.
I have screen sharing and file sharing enabled, and the firewall is set up to allow incoming connections for screen sharing, file sharing, and also Plex and all its helper programs. I don't think any of these should be the issue because I can access the mini with no problems SOME of the time just not all the time. Seems like if I haven't connected for some unknown amount of time this problem crops up. When it doesn't work I have to trot down to the basement, turn on the monitor (100" projection screen, so kind of annoying) and restart the computer. I have tried toggling "Put hard disks to sleep when possible," and that didn't seem to have any effect. I also have the energy saver set to wake for network access.
I do not recall having this problem as often, if ever, before I upgraded to Mavericks. Not sure if that could be part of the issue. One other quirk since upgrading to Mavericks is that upon every restart I am asked if I want to allow incoming connections for Plex and Connect 360, both of which are listed in the firewall preferences ad allowed programs.
Can anybody help?

Signature in Mac Mail keeps disappearing

I have to keep pasting the same signature in every e-mail, it will not retain my customer signature after the mail application has been closed. Couldn't find much info on this online, does anyone have any ideas?

I have the exact same problem. The image in the signature keeps disappearing. I can speculate that closing the mail app causes it to "forget" the image whilst leaving an empty Bo's in its place.

Router MI424WR - Device Names to MAC Addresses Question

I have Verizon FiOS with an ActionTec MI424WR Router. I have many devices connected to it on our home network: ipods, ipads, nook, kindles, laptop, roku, and a desktop.
For each device, I found its MAC address. Then I logged into the router and went to "My Network." There, I renamed each device (for example, from "android-alsdfjl3kljasdf" to "JonKindle" and "new-host-4" to "MaryIpad"). That way, I'll be able to go to the parental controls rules screen and assign each device to rules as I like.
Problem:
The names keep changing back to "android-alsdfjl3kljasdf" and "new-host-4". Not only that, but somehow, the MAC addresses keep changing. Is there a way to keep that from happening?
I thought MAC addresses were assigned to a piece of hardward and didn't change. Can someone please enlighten me?
Thanks,
smy

The trick to make the [name, MAC address] permanent is to assign a static DHCP lease to each device. Otherwise, when the lease expires and the device is no longer active, the router forgets everything about it.
As for changing MAC address, you are correct, they shouldn't change.
If you have multiple "Android-xxx" devices they may be coming up in a different order, thus creating the appearance of changing addresses. Make a list of every active MAC address and attempt to correlate it to your devices. The next time you think one changed, look and see if it's on your list.
MAC addresses can be changed by the user on some devices, however this is typically only done to "play" with a network or circumvent security features.
Good Luck.

Gspeed ES Pro RAID keeps disappearing from Mac, have to re-initialize!

UPDATED VERSION:
MAC PRO KEEPS LOSING CONNECTION TO RAID DRIVE.
After 9 months of organizing a documentary film edit on an external RAID drive (12TB, Raid 0. Yes, I have 2 layers of backup), I purchased the PNY Nvidia Quadro 4000 video card for the primary edit. Soon after, I began having boot up issues. The screen would freeze at various points during the startup process, requiring manual power-downs.
Over the past two months, my computer has lost communication with the RAID 3 times, forcing me to rebuild it from my backup drives (10TB). One tech at Diskwarrior said my computer lost the partition, and that the 1s and 0s had been largely replaced with gibberish.
The Raid becomes unrecognized by my computer in one of two ways:
1- After two days of copying data back over to the raid (rebuilding it), I get an error code -36, saying a file cannot be read or written, then the Raid partition disappears from disk utility and the next time I start up the computer says it doesn’t recognize my drive. The ATTO configuration tool (the card that attaches my raid to the computer) sees the drive, but my computer does not. I have to re-initialize it and start over again.
2- The Raid will go from being recognized to not being recognized when I reboot one day. Again, I have to re-initialize and rebuild.
I removed the PNY Graphics card and put in the stock ATI Radeon HD 5770 it came with. On day 2 of rebuilding the RAID, I got the error -36 and the Raid disappeared from disk utility again. When I opened the raid folder, which seconds before had 10 TB of data on it, it read as zero items. So the PNY Nvidia card was NOT the problem.
Apple has worked on the computer 3 times, running extensive hardware tests, but the same problem persists. At one point they said my blackmagic card was the problem, and more recently they said I probably have bad ram. I tried separate ram (the old 6GB my computer came with), and my computer seemed to begin booting up okay, but one day later I had the -36 error, the RAID couldn’t be recognized again and I lost the data during another rebuild. Apple even replaced the Ram Tray, but the same problem persists.
G technology says my RAID’s hardware is fine, and ATTO, who makes the Raid card, says it looks fine to them too. This does not mean they are 100% not the problem though.
Yesterday as I was attempting to rebuild the RAID again, I saw the -36 error come up, and files stopped copying. I immediately made a screenshot and noted the time.
Today I spoke with a really cool tech at Apple named Ron who helped me investigate the Kernel log, and this is what it said (the RAID is called FadingWest):
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs_swap_BTNode: invalid forward link (0xbb739311 >= 0x0000df00)
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs: node=2717 fileID=4 volume=FadingWest device=/dev/disk3s2
Dec 6 17:05:36 Jesses-Mac-Pro kernel[0]: hfs: Runtime corruption detected on FadingWest, fsck will be forced on next mount.
Ron believes my problem is with the RAID card. He thinks it’s dropping the connection. So I’ve got an RMA going with ATTO for a new one.
Here are the final things I can troubleshoot at this point:
New RAID card (ATTO)
New RAID drive (G-Technology)
Motherboard / PCI lanes (Apple).
NEW COMPUTER (Apple)
Any ideas are appreciated. Here are the items in question:
Mac Pro mid 2010 2x2.66 Ghz 6 core Intel Xeon OS X Lion 10.7.5
G speed ES Pro (G Technology) – 12TB @ RAID 0
ATTO R680 RAID card

I found this on another help site, I think it's the trick:
there are 2 halves to the Dock. With a bar in the middle.
on the left side, there are 2 sections. the furthest left are the icons that will stay in the dock, then on the right side of the left half of the dock, are the temporary icons, the ones that just stay there till the program is done.
You can freely move a temporary icon to the left and it will be come a permanent icon.
I am reminded of the wizard of OZ here... you could always get to firefox... you just had to click your mouse (and drag an icon)..

I started the CC (PS & LR) for Mac in October. LR keeps disappearing from the CC Apps group and shows up as "Install" in the uninstalled apps section. How can I fix this?

I started the CC (PS & LR) for Mac in October. Twice now the LR shows as "Install" instead of being one of my installed apps. The first time I spent 3 hours on the phone with customer support. He finally recommended deleting the app from my applications and then installing again. This worked for awhile but now LR no longer shows up as one of my apps. LR is on my Mac though and I have been able to use it, although I'm not using all it's features. Any clue as to why LR keeps disappearing form my CC apps?

Jeff, my rant is not directed at you as an employee of ADOBE - your prompt feedback is appreciated and will aleviate some of the antagonism I feel against ADOBE because of the business unit's decisions with litlle regard of the user's buying and using the software.
Shareholder must understand that if they try and force the hand that feeds them too far, it will stop.
I love what the software engineers are doing with the software and appreciate the individuals whose job (ADOBE employees/help desk sub-contractors) it is to try and assist, but, ADOBE’s image is tarnished in my eyes by their new subscription policy they are forcing on end-users.

Mac mail keeps sending emails from different accounts even though it says correct email in "sent" folder. Recipients reply and it goes to different email address. So confusing.

mac mail keeps sending emails from my different accounts even though it says correct email in "sent" folder and correct email account was highlighted. Recipients reply and it goes to different email address. So confusing and annoying.

Hi Mike,
I had the same issue and managed to solve it.
Go into Mail>Preferences>Accounts
Then in the account information tab, at the bottom should be outgoing mail server (SMTP) and click the drop down box
Mine had a few different servers in it so i went into edit SMPT server list. Click advanced and it will tell you which ones are going from which email address.
Delete the ones you dont want, and it should work or instead of deleting click use only this server, i imagine that will work to
Hope This Helps

Keep losing my wireless and mac addresses wont hold

For some reason, i could not delete or add any mac addresses to the aebs, which i have been using for the past couple years, so i did a hard reset on the unit. Now i have not added any security yet and the aebs keeps dropping my wireless connections. Any ideas?

To perform a Factory Default Reset......
Pull the power plug from the back of the AirPort Extreme
Wait 2-3 minutes
Hold in the reset button and keep holding it for 10-12 seconds while you plug the power back in to the Extreme
Release the reset button after the 10-12 hold period and allow 25-30 seconds for the Extreme to come back up to a slow blinking amber light
Before you start to reconfigure the Extreme again, power down your modem for 5-10 minutes, then restart it.

"Enter the Yahoo! password for [my yahoo email address]" keeps popping up on my Mac desktop

A pop-up window "Enter the Yahoo! password for [my yahoo email address]" keeps popping up on my Mac desktop (Leopard OS) every few hours. This has happened for the past year and only happens on my MacPro desktop, never on other laptops/computer. Does anyone have solution please ?

Ok !! I think I finally found the trouble of this !! I went crazy that every 5 seconds I had to fill in my password for my yahoo account om Apple Mail. My computer is in another language so I'll try to translate as good as possible the buttons and so ..
So these are the steps required:
You need to give computer access to the password of Yahoo.com. How to do so ?
You go to the application "Key Chain" that is included in your MacBook Pro.
Then you go to the first tab that should say something with "Login/Session" and you should see all your saved passwords.
Scroll down to the saved password of "Yahoo: your-username @ ...
Click on it, you should see a window opening
Go to the tab "Access Control"
Then click on "Allow all applications to connect .. ", NOT the option "Ask every time for allowance" or you can also just add the program "MAIL" with the "+" icon !!
There you go, now you should not have to worry again !!!!!!
Hope it helps people !!!

Address Book Keeps Disappearing

I just transferred 6000 contacts from Entourage to Address Book, and a number of times over the past few days the ENTIRE contents of the Address Book just disappeared -- often I've been able to watch them vanish one by one.
Luckily I've backed up regularly so the data was not lost.
But *** is going on here? Reading this forum, I see I'm not the first.
Is there a limit to the number of supportable contacts? Is 6000 more than Address Book can handle/
Also, I've noted that my Address Book is ballooning in size. It began at around 10 mb, then every time I've had a crash and replaced it with the backup, it grew. Now it's almost 30 megs. No photos etc. -- just basic address data and a few notes.
Is there a way to "compact" the database à la Entourage?
Lost count Mac OS X (10.4.9)

Checked that and I did sync contacts. I deleted all Mobile Me contacts and all contacts in address book and Turned Sync completely off. Restarted and Address Book disappeared from Dock.
Quess that I have another Lion anolomy that will just bug me forever.
There are several other Lion issues that are driing me nuts.
Thanks for your help.

Even with MAC addresses entered into Airport Express, my devices keep asking for router password. Basically, MAC filtering on my AirPort Express is not working

I just got a new laptop form work and wanted to add it to my home network. Even though I put in the MAC address, it continue to ask me to put in the router password. Not only that, it started to do that with my other devices within my home network.

With Airport Express setup being relatively quick and easy, I would put the work laptop aside while you reestablish your home network and ensure that your non-work devices operate without having to re-enter Router Passwords. Once that is done, I would turn the work laptop on and see if it discovers the home network. Once you have entered the network password once, look for an option to remember the network. It may be defaulting to your work network on each re-connect.

Mail messages keep disappearing

I bought my mac about a month ago and am confounded by the mail program. Seems messages keep disappearing from my inbox and also from my sent items. This morning I sent a message that I needed to call up again but it had disappeared. I've searched everywhere for answers to this but can't figure out what's happening. Can someone help?

Since you are accessing two accounts with Mail, there is an Inbox mailbox for each account and the same for Drafts, Sent, Trash and Junk when Junk Mail is set to automatic.
Open Inbox be selecting the black triangle beside it pointing it down to reveal the Inbox mailbox for each account. Selecting an account's Inbox mailbox reveals messages received by that account only in the message list. Selecting Inbox reveals a "blended" Inbox mailbox for all accounts in the message list.
The same applies to Drafts, Sent, Trash and Junk (when Junk Mail is set to automatic) in the mailboxes drawer.
Since you are accessing an IMAP account with Mail, there is also an account named icon for the IMAP account at the bottom of the mailboxes drawer. This includes the server stored mailboxes for the account with the exception of the account's Inbox mailbox which is located under Inbox in the mailboxes drawer. Regardless the account type, the Inbox mailbox for each account is located under Inbox.
So now, which account is missing messages - the POP account or the IMAP account and from which mailbox - the account's Inbox mailbox, Sent mailbox or both?
Are you storing sent messages on the server for your IMAP account which is available under the Mailbox Behaviors tab for the account preferences?
There is no setting to remove messages from the server with an IMAP account. Mail is keeping the server stored mailboxes synchronized with the server.
In order to create a separate account in Mail provided by the same provider, the account must be an actual account which means the account has its own user name. An additional email address that shares the same user name, incoming mail server and password as a primary email account is called an alias and you cannot create an alias address as a separate account in Mail due to the account and associated mailbox filing structure at the Finder level.
To add a alias email address to the primary account, go to Mail > Preferences > Accounts and under the Account information tab for the account preferences at the Email Address field, add the alias email address in this field separated by a comma from the primary account's email address. Save the changes when prompted.
All messages addressed to the alias address will be deposited in the primary account's Inbox mailbox and when wanting to send a message with the alias email address, select the address via the Account selection pop-up when composing a message.
