• Access to my printer wireless Macbook pro

  I have connected my Canon MF 6160 wireless printer to my network (bright blue antenna is turned on), but I can't add the printer to my macbook pro print menu or if it appears in the drop-down selection list box, it says that it is offline. Any suggestions? Bob

  This configuration has worked?

  The printer works when connected directly via USB?

  Did you reboot the printer so the router?

  If the printer is new, have you contacted Canon support, and what did say?

• OfficeJet Pro 8500 a: printer no longer works after reset wireless network

  OfficeJet Pro 8500 has, MacBook Pro, running the Mavericks.

  For 3 days, when we added a password and blocked our router wireless (modem ATT UVerse), our printer is "offline" print jobs queued, but do not print.  When I go and check it says "printer offline".  Or in the print queue, it is something like "looking for printer."

  He worked briefly when we found a power cord and plugged into the laptop, but will not work wireless, which he did before.    No changes except to repeat password for the network.

  I have the manual and you have turned off everything, then return in the order recommended (router, printer, then laptop).  Always offline.   Can someone please?   Thank you!

  Hello @LindaGrace,

  Welcome to the Forums of HP Support!

  I understand that since to add a password to your wireless router your HP Officejet Pro 8500 has e-All-in-One Printer not communicate wirelessly with your computer Mac OS X 10.9. I would like to help you today with this problem of wireless communication.

  Now, make a change to your network, as an addition to a password or change a password, translates into having to reconfigure your printer on the wireless network. At this point your printer is to be 'blocked' access to your network wireless because of the change you made. To correct this problem, you simply raise the Setup wireless for your printer to "say" the printer network name and password. Once the wireless installation runs successfully all will continue to work for you according to the normal.

  To run the Wireless Setup Wizard on your printer, please follow the steps below.

  1. On the touch screen of the printer, press the right arrow key () to display the second navigation screen.
  2. Press network () to open the network Menu.
  3. Touch Wireless.
  4. Press the Wireless Setup Wizard, and then press continue.
  5. Please wait while the printer is looking for the routers that are nearby. Appears in the menu Select Network (SSID) .
  6. Scroll the list of network names until you find the name of your network.
  7. Tap the name of your network.
  8. If you are prompted, enter the WEP or WPA key. This is the password for your wireless network. The password is case-sensitive.
  9. Wait for the printer to connect to the network

  -Source

  Once your printer is connected to your network again, please try to print. If printing still fails, you need to add the printer to your Mac because of the connection of network new printers. Please follow the steps below to add the printer to the Mac.

  1. click on the menu of Apple , then Preferences System.

  2. click on Print & Scanand then check if the name of your printer appears in the printer list.

  3. If your printer is already listed, remove and re-add the printer to check the communication with the Mac. Click on the name of your printer, click the minus sign (), and then delete the printer

  4. click on the plus sign (), click Add a printer or a Scanner, click the name of your printer

  5. click Add to add the printer to the list.

  Now that the printer is properly configured on your network and added to the Mac, please try again to print wireless.

  Please reply to this message with the result of your troubleshooting. Good luck!

• OfficeJet Pro 8600 Plus: loss of wireless connection, printer does not accept the password wireless

  My printer has suddenly lost its wifi connection. It's the only phone connected to my network to do so.

  Through the Wireless Setup Wizard to restore the connection. Assistant tells me that I entered an invalid password wireless, that is not true. (I confirmed that all devices connected to the network using the same password).

  Reset the router (Technicolor of Time Warner). Reset the printer. The 'Restore default network' done. No luck.

  Zero has changed since yesterday, when my printer was working fine. I used the same router for months, do not change any settings. Any thoughts on what may be the issue? A bad update happen?

  Thanks in advance.

  My apologies for the late reply. I managed to get this problem resolved by phone to customer service.

  The security mode of the router had to be changed to 64 WEP for wireless connection to be restored. According to Support HP, it's a common problem with the routers in Technicolor. There was no explanation as to why the printer has suddenly lost the ability to connect wirelessly when safety was created to WPA2-PSK. The network has been configured this way for more than a year.

  I have almost solved this problem on mine (I had read about changing of security in a different post), but ran into a hiccup because of Safari. For some reason, Safari prohibited access to a menu page for my router security settings. You can imagine how boring it is to look at the HP Support use Firefox to access the router and do what a mouse click more, and then I had to make the change. So, if you make this change, be sure not to use Safari to access the gateway of the router Technicolor. Use Chrome or Firefox.

• The Sierra of MacOS will propose for the Mid 2009 MacBook Pro in the near future?

  I have a model Mid 2009 MacBook Pro and when I try to upgrade the software of OS systems to the Sierra, he refused my request to download because it "cannot be downloaded to this computer." I noticed other Mac computers, for example, iMac Mid 2009 or newer and MacBook Mid 2009 or more recent systems only one are close to mine are candidates to download the software, but the MacBook Pro is the only one that is not on this list for availability. So, my question to my question is, will be available Mid 2009 MacBook Pro updated to day for Sierra anytime soon? And if not, why?

  Please let me know what your answer is as soon as possible.

  Thank you!

  My answer is no.

  However, as long as I and everyone here, do not work for Apple, my answer is certainly not authoritative.

  However, as I've used Apple computers for more than 30 years, he never had a case when they released an additional OS that works on previously excluded material.

• Remove the user on MacBook Pro OSX10.11.6

  I chose to delete a user on my Macbook Pro that is running OSX10.11.6 El Capitan, and he is now 72 hours later and there is no sign whether he actually remove... There is no status bar. The user name is italic and he says "deleting account...". "under the user name, but this has been the same for 72 hours. Is all the same to say if she would actually delete the account or if it is frozen? I am currently unable to shut down my computer and I don't like leaving on this long. Everyone knows that long? Is there anyway to check the status? I just manually should the computer by pressing the power button / stop?

  Any advice would be appreciated.

  Probably this thread might help you: deletion of user account takes now 24 hours, why?

• How to replace the logic board MacBook Pro mid-2010

  I have a MacBook Pro 13-inch mid-2010. About once a week, monitors (one who is part of the laptop) and an external will turn grey and freeze. When I turned off the computer, it brings back me to the login screen (I'm under 10.11.5), but I can't move the pointer (whether with my Apple Wireless Mouse or trackpad) to select the icon for my login. After a few reboots, the computer takes care of the password reset function. And there, I can reuse the mouse, select Restart the machine, and I'm back on my way.

  The genius of Apple and I suspect that the problem is with the logic board. Unfortunately, Apple has more parts for MacBook Pro mid-2010. I contacted a few service centers certified Apple the kind told me; None of them can help either.

  Any suggestions for how I have a fix for this problem? Thank you!

  You could contact a specialist to see what their requirement is to send you the

  computer while for a diagnosis appropriate; a specialist is the one who can do all the

  works internally and could actually fix the edge logic that the Mac came with.

  I know some who do this; they charge more than a parts Exchange hosting.

  You can see what a company such as wegenermedia can do. Or see what the

  iFixit guide for Mac (for your specific model) said repair and watch to see who

  part numbers are involved in replacement of the like-kind in refurbished or tested

  OK, from sources such as powerbookmedic.com and other sources used parts.

  The logic board may not be a problem; might be some on the Board of directors or of one which

  attached to, such as the graphics processor. These older models are not

  so difficult for a specialist expert set. While the Mac is able to do so, is a good time

  for they provide labour expertise to swap upgrade replacement parts.

  They can test the feature set and should provide a guarantee for employment.

  Some of these companies repairs also restored the supply of older computers they fixed.

  Good luck & happy computing!

• restore the firmware for macbook pro 13 mid 2009

  Hi all! This is my first time using the support community so forgive me for any rudeness and English summary.

  I recently bought a used mid 2009 macbook pro 13 "with no disc on this subject, I installed a new empty 120 GB ssd drive.

  I asked a friend and he has downloaded and made me a usb bootable with osx on it (lion). I instaled the osx and got the macbook running successfully and it was perfect.

  I decide to update and went up el capitan wich sucessfully installed. After the update I tried it out, web navigation simple, when suddenly, out of nowhere the mac stop (much battery left and the led indicator to confirm) and has not started since... when I turn it on the led light flashes and it gives the s.o.s. beep (3 short beeps followed by 3 long beeps and then 3 short beeps) the optical drive made his usual looking noises of boot and the fan continues to spinning, I tried to remove the battery 10 minutes several times and nothing... I read a lot about the problems of ram tested with one stick at a time in the two slots and no improvement... bought a new pair of hynix 2 gb 1066 mhz pc3-8500 ddr3 sticks as recommended for this model and replaced the "old"... did nothing.

  I have no original discs just the macbook itself and the charger. Also tried to boot from the usb drive... not good... tried to start mode revovery... nothing that the black screen and a beep sounds.

  I did some research and read a looooot online and in discussions such as this apple and found it to be the sound warning for bad/corrupted efi rom (as opposed to the majority of people declaring it to be a ram issue) which needs to be restored or flashed... However, apple does not provide or at least I can't find a picture of recovery for my model cd special I know it's the macbook 5.1 (a1278 / emc2254). Is there any solution for this? Please help in some way that you can welcome suggestions!

  Thank you
