Trying to MacBook Pro Retina 10.9.5 to Canon C5250

I have a MacBook Pro Retina 10.9.5. Trying to print to the Canon iR-ADV C5250 in my office. I downloaded the most recent driver off of Canon's website and have the printer's (correct, I think) IP Address, but, when I try to "add" the printer, it says "Unable to verify due to an error."
What do I need to do?

Yes safe mode works. I have repaired the disk using safe mode doing it twice with an "appears OK" I just reset my admin password and restarted the computer to see an apple on grey screen with swirly loading symbol then it goes black with a white a white highlighted arrow after clicking the mouse pad.

Error while trying to install safari extensions on Macbook Pro Retina

Dear All,
Yesterday I had to re-install Mountain Lion OS on MacBook Pro Retina. Everything went smoothly however after the installation process and updating sytem to the newest possible version, I am not able to install any Safari extensions. I was trying to find any information in the internet about this but so far I am unsuccessful in solving this issue. I am currently running Mountain Lion 10.8.2 and Safari 6.0.1. I would be grateful for any help.
Best Regards,
Jan

Back up all data now.
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. If none of this is meaningful to you, you don't need to worry about it.
Step 1
Launch the 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.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:20 ~ $_ ; chmod -R -N ~ $_ 2> /dev/null
Be sure to select the whole line by triple-clicking anywhere in it. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. If you don’t have a login password, you’ll need to set one before you can run the command.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2
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 text window opens.
In the Terminal window, type this:
resetpassword
That's one word with no spaces. Then press return. A Reset Password window opens. 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.

HT5634 Late 2013 Macbook Pro Retina only support Windows 7 (Trying to install 8.1)

I have a 15 inch Macbook Pro Retina (Late 2013) trying to install Windows 8.1 (64-bit) via Boot Camp on USB with an ISO. Upon downloading Windows support software, I'm greeted with a pop-up that says: "This Mac only supports Windows 7, do you want to continue?" However, upon further investigation, according to Apple's website, it says my model is officially supported for Windows 8.1 What's going on here?
Boot Camp: Version 5.1.2 (481)
OSX Version: 10.9.2
Thanks!
-Sterling

I am new to the community as well but have been an apple genuis for a while. The way I put windows on my mac (late 2012 pro) last year was I bought windows 7, and used bootcamp to install it. I would have someone at best buy or a tech store do it for you though. If you dont want to pay $200 for windows 7, you can just buy an app called parallels (also at like a best buy) and use that. I believe it is around $75 but not sure. Hope this helps

When trying to Airplay from my Macbook Pro Retina, to AppleTv3 it plays for only a few minutes, and then jumps back to the Mac. It seems to do this no matter what I play, music, movies or pictures. I just bought a new router. This could affect it

When trying to Airplay from my Macbook Pro Retina, to AppleTv3 it plays for only a few minutes, and then jumps back to the Mac. It seems to do this no matter what I play, music, movies or pictures. I just bought a new router. This could affect it.
I have been playing whole movies before from VLC without problems.
Any Ideas?

Welcome to the Apple Community.
Yes it's network issues or settings that cause these types of problems most of the time.
The following article(s) may help you.
Troubleshooting AirPlay
Troubleshooting Wi-Fi networks and connections
Recommended Wi-Fi settings
Wifi Diagnostic Software (for Mac users)
You may also find some help on this page, where I’ve collected some of the more unusual solutions to network issues.

Trying to find source of Macbook Pro Retina kernal panics (system report in post)

My Macbook Pro Retina running Mountain Lion has at least one kernal panic a day. Sometimes the wallpaper resets to default. It only happens while it's asleep and I have only ever once caught it on the error screen (meaning it's not happening as I wake it up but rather while the screen is off). I have had my computer and this problem for a while so I finally tried taking it to Apple to resolve the problem. It's been confirmed twice not to be a hardware problem and I have had the entire logic board replaced.
All other threads seem to say the problem is bluetooth but I never use bluetooth and it is always off. I DID do a full system reset and the problem went away but restoring the computer from time machine brought it back after a couple days. Is there any way of figuring out what software is causing the problem? Is there a way to use time machine to migrate applications and files to a reset computer instead of doing a full system recover and would that possibly fix the problem?
I would like to avoid updating to the newest OS if possible for reasons.
Here is the system report:

hienn,
Not yet. There was an upgrade page to 10.8.2 for the late 2012 models but it's down now. I have to assume that Apple pulled it because of some bugs. I would look for something next week, more likely than not. In the meantime, the OP should be good with 10.8.1 until the update shows up again.

Early 2013 Macbook Pro Retina 2.7 i7 512GB SSD and 16gb Ram with Serious Cuda Problems! Trying to teach Apple their Macbook Pro Retina isn't a Pro Jan. 11. 2015.

Apple replaced the logic board, wiped the computer, did a fresh instal of the OS, and also a fresh instal of all the programs during the beginning of 2015. The GeekBench scores are the highest of any of the similar computers (at least on the day of my testing). But here's what's happening. The Macbook Pro Retina has a GeForce GT 650m with Cuda Technology and it can't handle editing in Premiere Pro with Cuda Acceleration turned on. Open CL, a second form of graphic acceleration on the Macbook Pro, appears to be functioning properly.
At the Apple Store on 1-10-2015, I was told that since the logic board and the graphic cards have been replaced that there is nothing they can do and they recommend contacting Corporate. This comes after they told me to buy a new logic board and that that would solve the problem. This comes after Apple did not listen, for over a month, about the possibility that they didn't properly build a professional notebook computer.
The computer displays a black program monitor screen, at random times, when the user edits footage with Cuda Acceleration enabled. It used to lead to an entire system crash and/or a Premiere Pro crash before the operating system was completely re-installed. My solution, since I bought the computer, was to edit in Open CL... However, I've come to learn that there is a major difference in performance between Open CL and Cuda Acceleration.
For the Macbook Pro Retina, Adobe Media Encoder render times are about 20% faster with Cuda Acceleration than Open CL. The 2013 Macbook Pro Retina appears to be able to handle Cuda Acceleration in Media Encoder, but I have had a number of issues leading to program crashes on every project before the new logic board and operating system were installed. For over a year and a half, I actually never used Cuda Acceleration. Having sent every crash report and user data to Apple over that time, I truly expected an update of some sorts and it never came.
FYI: The latest Macbook Pro Retina uses the GeForce GT 750m... This is essentially the same graphic card that performs about 10 - 20% faster due to a new "boost mode." More importantly, it actually has the exact same number of Cuda cores. Having the same number of Cuda Cores means that the Cuda Acceleration is essentially the same when exporting or viewing video. To prove a point to Apple that their 2013 Macbook Pro Retina isn't functioning properly, I bought the latest computer with the 2.5 i7, 16gb Ram, 512gb SSD and I can honestly say that the 2014 model works perfectly fine with Cuda Acceleration turned on while editing in Premiere. I can also say that a proper render test proved the 2013 and 2014 model to be the exact same.
I'm new to this whole pay $2700 for a computer that your manufacturer didn't / can't test properly, so I will be contacting Apple and speaking with Senior Advisors, their Customer Support division, and will soon speak with their Corporate branch. I'm confident that the Early 2013 Macbook Pro Retina with a 2.7 i7 16gb Ram and a 512 SSD is nearly the same at rendering video and editing video, provided the Cuda Acceleration works, as their latest 2014 Macbook Pro Retina with the 2.5 i7 processor 16gb Ram, and a 512 SSD. It's truly a great computer and a great build, minus their current inability to properly test / diagnose their computer.
Knowing that the latest graphic card in the Macbook Pro lineup is essentially the same model, I feel that Apple is not directly looking into the viability and life span of their current Macbook Pro Retina product line. They can't test for performance issues relating to their graphic cards, so why consider buying from them when the end user is actually in a position to experience up to a 20% decrease in certain professional programs.
For future reference, I'd strongly urge other individuals to avoid purchasing Apple products if they offer Cuda Technology. In my opinion, Apple is an Open CL organization, at best, who is not responsibly manufacturing / producing computers that fit their organization's strengths. For a fact, they can't test their Cuda Technology and won't even attempt to address Cuda Acceleration errors for Apple owners (01-11-2015). I say this having walked out of the Apple Store on 1-10-2015 with virtually no support other than to contact Corporate.

I have a Macbook Pro Retina Display and it keeps flickering. Very annoying. Almost seems like something else is trying to open.

My macbook has suddenly started flickering. I hadn't updated any software. I did go and update to OS X but that didn't help. Is anyone else having the same problem?

Hello abmorgan646
Check out the article below to try out a few things to resolve issues with the flickering display on your MacBook Pro Retina. You may need to reset the NVRAM, if it does not resolve the issue, then there are links fur further assistance.

Macbook pro retina doesn't turn on for a day or two

Macbook Pro Retina 13-inch Late 2012
2.5GHz Intel Core i5
OS X Yosemite (10.10.2)
So this is a weird one... I recently purchased a used Macbook Pro Retina and the previous owner had upgraded the hard drive for a bigger size. My macbook worked great for a few days but then one night I closed it and the next day when I opened it, it would not turn on. I tried rebooting the battery (SHIFT+CONTROL+OPTION and POWER) then hitting power but NOTHING. At one point, I heard a clicking sound when I would leave the power button down. Then... two days later I push the power button just because and BAM! The screen comes on. (I didn't hear the start up sound, and it wasn't like it restarted.) It was as if the screen brightness was all the way down but then came back. (I kept trying to adjust that too before it turned on).
I don't understand!!! Two days later, same thing happened. Then again, it turned back on a day later.
The only thing I noticed that was weird was when I connected it to my tv with HDMI cable. The laptop screen would freeze and get distorted and I would have to force a restart (the black screen with the apple would appear and the loading bar as if I would updating the software).
I'm soooo confused and I don't want this to keep happening. I would appreciate any type of help or advice!!

Hi RACan2,

My iPhone 5 won't connect to my macbook pro retina over bluetooth?

My iPhone 5 won't connect to my macbook pro retina over bluetooth?

Ah, sure it actually won't. I have the same problem, and I contacted Apple Support. They told me that there is an incompatability between the iphone 5 and MacBook Pro Retina such that Bluetooth pairing is not possible.
The Support Agent actually had the audacity to tell me this was part of the design of the OS on the MacBook Pro, like Windows people saying, "That's not a bug. It's a feature!!"
Personally, I think this is insane. While I was trying to tether the iphone to the MacBook Pro retina for an internet connection, there are other reasons related to file transfers for which one would want to pair the iphone 5 with the MacBook Pro retina.
I am hoping this "feature" is fixed in iOS 7, and/or in some dot release of Mac OS 10.8.
By the way, the personal hotspot feature on my Verizon iphone 5 works great either via a wifi or USB connection. There are occaisions, however, when one would 1) not have a USB cable, and/or 2) have another wifi relationship between the phone and a network that one would not want to have to "forget" in order for it not to connect to that wifi network. The Macbook will not find the iphone as a wifi hotspot if the iphone is connected to wifi in the first place. At least mine won't.

What hbmi cord do I need to connect my Macbook Pro retina display to a Windows desktop?

I'm trying to connect my Windows desktop to my Macbook Pro retina dispay so i can transfer CD's. ALthough I dont know what cord to get.

Your post is a little confusing. HDMI is for connecting video, like hooking your Mac to a TV. It sounds like you want to transfer files. If you have a wireless network, just share the folder with the music on your Windows machine and you should be able to copy it to your Mac.

How do I connect a 2013 Macbook Pro Retina to an Epson Power Lite 61p LCD Projector?

I am trying to attach an Epson PowerLite 61p LCD Projector to my 2013 Macbook Pro Retina, but I cannot find which type of adapter I need. I would assume whichever adapter is required it must connect via thunderbolt. However, I do not know if the required adapter is a "Mini Display Port to VGA Adapter," "Apple Mini DVI to VGA Adapter," or a "Thunderbolt to VGA Adapter." I would deeply appreciate your help and guidance. Thanks!

It does not matter whether you get an Apple adapter or a third pary one. What you have there is a Mini Displayport to VGA adapter, but as you know, your new MacBook no longer has an MDP port!
Thunderbolt to VGA adapters do not exist but there are plenty of HDMI to VGA adapters out there:
