  • Unable to connect C4780 with Mac Pro wirelessly

    When i tried to conner Printer C4780 wirelessly to Mac pro it says that the  selected printer software isn't from the manufacturer and may not let you use all the features of your printer. The software that i installed is one which i received when in brought printer in PC World in UK. It does connect with USB but not wireless.

    Hi @Krish1840 , and thanks for the reply!
    Do the pages come out blank when making a copy as well?
    I would suggest deleting the printer from your print system, using this document: Uninstalling the Printer Software.
    Once you have deleted it, I would suggest verifying and repairing the disk permissions: About Disk Utility's Repair Disk Permissions feature.
    I would also suggest running your Apple updates:  OS X: Updating OS X and Mac App Store apps
    After the updates, I would recommend readding the printer via OS X v10.9 Mavericks: Installing and Using the Printer on a Mac
    Good luck and please let me know how it goes!

  • First time user trying to set up new Mac pro, wireless mouse and wireless keyboard together?

    So  I just bought a new Mac Pro, wireless keyboard and mouse. i am a first time Mac user. How do I even get started......connect the wireless mouse and key board to the Mac Pro desktop to even get started??

    Just turn on the mouse and keyboard and observe that the green light comes on and starts to blink then turn on the Mac. The Mac should give you on-screen instructions.

  • Unable to open Mac Pro Superdrive

    I'm currently unable to open my superdrive on my Mac Pro and am looking for any tips on how to correct.  I was thinking about installing a blu ray drive in my Mac Pro and had watched the proper instructions on how to accomplish this task.  I had the drive installed on the bottom rack and decided to abandon the idea and just keep with the one drive.  So, after putting everthing back where it should be (supposedly) I'm finding a misalingment on the hinged dust cover door that prevents my superdrive from opening at all (see photo).  I'm at a loss on how to make an adjustment to correct this and was hoping someone might have some hint to share.
    I've included pics that show the misalignment if it helps to demonstrate where the problem lies.  Any suggestions would be greatly appreciated.

    yeah, alignment can be a pain. should be as easy as making ice, but somehow it isn't. Check to make sure the drive is fastened correctly into the sled on both sides.  make sure that the sled hits all the pins as you slide it in. Make sure that the cable is tucked well out of the way and isn't stuck/binding on anything. there isn't a lip on the disc tray is there? I think there might be a screw on the side of the hinged door which might help or not--could be tight. looks to me like one side is a bit up and the other side isn't. may a little push in the right spot might help....
    if you're still stuck I think there's online videos on how to put a drive into your Mac Pro which might help you out a bit

  • Mac pro wireless problem osx 10.9.4

    Mac Pro n
    Had wireless problem after 10.9.4 update.
    Various things it may say: move router closer, or invalid password, or time out.
    Tried all the solutions normally provided. Restarting, running this, doing the airport tests, more this and that, etc... no go bro! Searches returned similar problems but no real answers.
    SO....
    I changed router channel from 6 to 7, you can change yours to what ever channel you like, and restarted router.
    In NETWORK preferences the wireless light was orange and not connected. Network connection shows my network though.
    I then went into NETWORK > ASSIST ME > DIAGNOSTICS >The Network Status light for Wi-Fi was green but all others below it were red.
    I then typed in the name of network connection and the password in the wifi settings and it said wrong password, I did it again and a drop down box said "network changes detected"
    Wahoooo That is the ticket!
    Then re-enter the Connection Name and Password and it should connect.
    All the lights should now be green on the Network Status (ISP, Internet,etc)
    Lucky Me!
    Question is:
    How do I manually get my connection back rather than hoping and praying the Mac Pro will finally detect something different and then allow the connection.

    Try updating to 10.9.5. I had similar problems before updating.

  • Mac Pro Wireless

    Howdy,
    I bought my Mac Pro in march 2007 (to give you an idea of the age). I have been running the internet through an airport base station so that my wife has wireless for her macbook, and my mac pro was just hardlined into the airport base station. Now we have moved and I now have to have the base station in a different room as my computer. I once thought that apple had a wireless card you could install on in the mac pro to make it wireless. I am now reading that apples wireless card doesnt work with the mac pro... is this true and does anyone have a suggestion... thx

    Amazingly enough Kappy is right and you are wrong on this.
    OP: Try this - USB 802.11 for macs
    https://eshop.macsales.com/item/Newer%20Technology/MXP802NU2C/
    And it is $50 and works vs. $60 that won't.

  • Mac Pro wireless upgrade

    I have an original Mac Pro from 2006, and I just had a airport extreme card put in. What I need to know is, if I purchase a 802.11n router will I be able to use the n protocol on this mac? With or without the enabler?
    Wireless Card Type: AirPort Extreme (0x14E4, 0x87)
    Wireless Card Firmware Version: Broadcom BCM43xx 1.0 (5.10.38.27)

    Open up your Applications folder. Click Utilities then *Network Utility*. The information you're looking for should be there!

  • Unable to mack Mac Pro discoverable.

    Recently installed a Bluetooth module in my Mac Pro.  It worked fine, until I powered down the computer.  When I restarted it, it was as if I had never paired my trackpad with it.  In the system profile bluetooth power was listed as off and discoverable was off as well.  In the bluetooth preferance pane I clicked the 'on' button, but the 'discoverable' button was greyed out.  Once I turn the bluetooth power on, and connect the track pad it will work.  However it will not pair w/ the track pad, just connect.  And I never can get access to the 'discoverable' box.
    Any ideas?  I read through various threads and tried their recommendations:  deleting bluetooth preference files, purging the PRAM and nothing has worked thus far.
    I appreciate any suggestions.
    Thank you.

    Check your bluetooth to see if you installed the right antenna? What mac pro do you have? In case you did not know the bluetooth module is not a user installable part and if you are still under applecare, you might have just voided your warranty.. but I don't think its a major problem at this point. Check to see you have connected the right wire(it will say BT on it) to the plug on the card. You might have to use something to snap the antenna in place or try to go side to side until the connector is fully making contact.

  • Mac Pro OS X 10.5 cannot print to Canon iR2220i

    Hi, there - ! Having just migrated from PowerMac G5 OS X Tiger to Mac Pro OS X Leopard I find I cannot print to my Canon iR2220i via ethernet. All other printers - LaserWriter 16/600 , Brother laser colour, Epson Stylus Pro 3800 - are reachable. Have tried with original PPD as well as the most recent one from Canon's website, have tried Appletalk/IP-printing, etc. A specific iR2220i is and has not been available, but the iR2220 used to work.
    Would be most grateful for advice here ...
    Best regards,
    Adam

    Hi Adam,
    For the record, the Canon v1.81 driver does work on Leopard, so there must be something about your setup that is stopping it from working. Do you have the Firewall enabled on Leopard? I cannot remember ever testing if this causes an issue with the driver, but considering that the driver has to communicate with the printer to determine which model to select from its list, then an enabled Firewall could be the cause of the error.
    As a test you could also create another printer queue but this time selecting Generic PostScript for the printer model. You can select IP > LPD for the protocol, which is what the PS driver would be using, and enter the IP address and queue name of LP. If you can get this queue printing then that confirms all the network and machine settings are okay and that something must be amiss with the Canon driver.
    Note that there is also a PPD option for the Canon iR's. If you get the Generic PS working and want a bit more finishing support, then this can be another solution. You can download from here...

  • Mac doesn't communicate with Epson CX7450 printer

    Couple days ago, while trying to fix a problem with my printer, I messed the settings for the printer. I don't know what I did, but there is no "Printer and Fax" icon in the System Preferences. When I press Print and get the printer setting I find the settings for CX7400 printer and not for CX7450. What should I do to correct this situation and get my computer talking with my printer.

    You could do an Archive and Install - the important part is reinstalling parts of the system. Here are links that explain the various installs:

  • CS3, Mac OS 10.5.5, Epson 3800 Printing Problems (v6.11)

    Since recently migrating to MacIntel running an obligatory 10.5.5 , I've been encountering problems printing to my Epson 3800 of 2 kinds that had previously not arisen on PPC based Macs using 10.4+: 1) When switching media that requires a change of black ink (photo black to matte or vice versa) there does not seem to be a straightforward way to go about this without encountering glitches (previously this had been handled smoothly by the driver); 2) The driver indicates randomly that my paper feed parameters are incorrect for a given job, when in fact this is not the case, and this makes printing needlessly irksome and inefficient. This is a marvelous printer that I've been using for the past 15 months so I'd appreciate any suggestions that would allow me to remedy these problems.

    Dear Ralph,
    Thank you for replying to my post.
    It does not seem that I will solve my problem by localisation "rectification". I am in an all International environment. Hmm.
    Do you use InDesign CS3 in a totally colour managed environment?
    I just got a Colour Profile done for my Intel Mac machine from InDesign and it is 'less than perfect'. Very frustrating.
    This colour expert suggests I set up my work flow as follows:
    [Well if I was allowed to include snapshots of my screen they would appear here.]
    The Printer Profile I am using in the Colour Management dialogue box is the profile provide by the Colour Expert.
    How do you set things up please?
    I had, in fact still have, an Epson 3000 that the Colour Expert profiled and gave me phenomenal colour accuracy up until OS 10.5.5 when the Epson driver became non-operational. I am so disappointed that I am having so much difficulty with the 3800.
    I think there are Adobe v. Mac issues plus driver problems!!!
    If you can shed any light on this, I would welcome it.
    Thanks.

  • Unable to reconnect to wireless network after closing lid on macbook pro

    After installing recent software updates, I am unable to reconnect to my wireless network when I close the lid on my macbook. It says that it is "connected", but I can't access any website, check e-mail or ping any external server.
    I've never had a problem before, but now that I've installed software updates in the past few weeks I noticed the problem.
    Anyone have any ideas?
    MacBook Pro (Intel)   Mac OS X (10.4.9)  

    which ultimately means apple didn't do enough testing before releasing the last patch
    This is not always, and may not be, the case. What many don't realise is that many 3rd party developers stray from the 802.11 series specifications in an attampt to boost speed and get one up on their competitors. For instance D-Link, amongst others, use a short preamble setting by default in some of their routers to improve performance. However, this is non-standard and when it comes across wireless network adapters that don't support this then you have problems. They assume that their network adapters are being used for "maximum speed and compatibility". Whether Apple should or should not support a short preamble is another subject altogether.
    However, I do agree with you in that Apple should put more work into their Airport software.

  • Can I use a usb and wireless keyboard at the same time on a mac pro

    I wish to use the Mac Pro USB keyboard for Logic shortcuts and the Mac Pro wireless keyboard for normal typing etc. Is this possible?

    Just as Matt has said, the Mac uses "all devices active" philosophy with keyboards and pointing devices. It does not automatically Switch to a later-installed device, it uses them ALL at the same time by default.

  • Wh does the internet connection keep dropping on my macbook pro and mac pro

    I have a Mac pro, Macbook Pro and iphone. All have problems with the internet connection especially after any short period of in activity. My mac Pro is connected directly with an ethernet cable and the mac pro wireless. I have to go through system preferences network setup all the time to reconect. Soemtimes whn on email choosing take all accounts online does cause a reconnect but only after a minute or so wait.

    Done that.. many times... also did a lot of suggestions from other posts.. removing pls files etc.. nothing works and it seems to be something experienced by other.. mysstery is it happens on all 5 computers in the office.. my isp has no suggestions... the pro can loose connection and the macbook wifi is OK and the phone usually works OK but leave my Macpro for 5 minutes and `I need to reconnct using system preferneces...
