This printer does NOT play well with Mac!  Although it advertises wireless connectivity, none of the wireless setup instructions I've found & followed work (and I'm not a newbie).  I seem to've gotten it to connect for printing by accident. It prints okay, though it takes [forever] to actually get started.
I've been UNABLE to successfully get it to scan. It won't scan from its control panel, and when it does finally scan through a very cumbersome interface on my Mac, it does not recognize print material nor does it scan in a decent resolution as JPEG.
Don't be fooled!

The Mac Pro has a lot of problems. Nobody really seems to buy them for quality, which is good. The computer is completely unsuited for professional grade applications, and Apple's questionable configuration and outright counterfeit parts make this computer simply unfit to handle professional-grade computing.

A common misconception among Apple users is that Xeons are magical performance unicorns. They're not. They have precisely two advantages over a Core i7. One is that a Xeon supports dual socket motherboards. But since no Mac has these, that's not important. The other feature is ECC RAM support. The Mac Pro has ECC system RAM, but not ECC GPU RAM, so any GPGPU application you run on the graphics cards could result in corrupt data that lose you days or even weeks worth of work, should you attempt to use this computer professionally.

Another problem is that the performance of the "FirePro" cards is terrible. Apple didn't use real FirePro cards in the Mac. They used two-generation old RadeonHD chipsets that are 20-30% slower than their current generation R9 counterparts to begin with, and that was before Apple underclocked them for the Mac Pro, so performance drops even further. The only thing that makes these "technically" a FirePro is that this is what the firmware identifies them as. They don't have ECC RAM or the performance level that professionals might be expecting.

The Mac Pro is non-upgradable. It won't accept off-the-shelf graphics card or CPU upgrades. The upgrade procedure for Apple products is "Throw Apple product in trash. Buy new Apple product.".

In closing, just get a PC, and you'll be much happier.

Doesn't work reliably with Macs. Drobo support is terrible, taking weeks to answer support tickets and then closing them for no reason.

DO NOT BUY if you have a MAC! This printer is really not made to work on a MAC Operating System! I have tried for hours to make it not cut off the top of the page when printing from the Internet and downloaded multiple drivers! Nothing will fix it! Save your money and buy any other printer than this one! I have wasted too many hours trying to make it work! It was so horrible I just put my old printer back! I am in the process of returning this one!

When I first formatted it for Mac using Disk Utilities and tried it from my laptop it was ok. When I connected it to my iMac and tried to put real work on it for backup, not only did it fail, but it also caused my Mac to reboot spontaneously. Twice. I returned it and will not buy another.

It claimed it could be used on Macs, and itself is an excellent stand alone machine, but.....
The software for both Mac 9 and X is extremely worthless.  I bought it half year and I still can only use it as a stand alone copier.  Even the newest software from HP cannot get it to work on my OS 9.  Very disppointed.  Even writing several times to the customer service, the answer is: "there maybe something wrong with your software."  Poor support for Macs.
HP is very good at hardware, but when it comes to software for Macs, ...[it's bad].  I have a 1200 in office and the software for Mac is also having problem.  I suggest HP abandon its support for Macs and it is better off than claiming its support but actually there is no support at all.
If you own a Mac, do not buy this kind of printer.

I bought this in August 2014.  I have a Mac and this printer has not been able to get along with Mac since day one.  It took hours to set up the printer.  I would not "find" my Mac, although it's wireless.  I finally got it to connect, but all it does is print.  This seems to be build for PCs rather than Macs.  I have never been able to get it to scan or to use the Fax.  I constantly get the message when I try, that it's not connected to the PC - even though it will print.  The Canon website is completely useless.  Again, seems like they are geared more to PCs.  I am especially frustrated tonight, because I have an important document to scan and send, and cannot use this printer to do it.  It's noisy, can't print 3x5 index cards, which I use a lot for my business, the print quality is week.  If I could return it I would.

It didn't work with my MacBook Pro 13-inch mid 2009 (MacbookPro5,5) or MacBook 13-inch late 2008 Aluminum unibody (Macbook5,1).

The MBP didn't recognize the drive at all and totally invisible from Disk Utility and System Profiler.  The MB recognized it but kept getting stuck during OS X (10.8) installation, or start up after installing the OS through the USB adapter.  It worked with both Macs through USB but not through the internal SATA port.  Both of our Macs have the latest EFI and SMC, and I also tried resetting the PMU and SMC with no luck.  Of course, I repartitioned the SSD with GUID, formatted the partition with Mac OS Extended (Journaled) and tried clean installation of the Mac OS, too.

I thought of updating the SSD firmware, but to my surprise, they even didn't provide a way to update it on a non-Windows system.  The firmware updater program in the bootable ISO image keeps erroring out on our Macs.

I contacted Samsung tech support and first asked them if the 830 was backward compatible with SATA II.  They told me it was supposed to work, but couldn't figure out what's wrong, and yet, they didn't think there's anything wrong with the unit.

This was my second SATA III SSD after Crucial m4 I purchased a year ago.  The m4 installation was straightforward and it has been working flawlessly.  The performance wasn't that great initially but they improved noticeably with a firmware update.  Perhaps I shoud get another m4 instead of a 830.

I ended up leaving this printer outside the door of the Office Depot that wouldn't take it back. It's that bad.
First, it is NOT compatible with a MAC. Don't believe me? Check the box. You will NOT see Apple's trademark.

But it is the ways in which it is not compatible that were astounding. First, the warm up time when it did print was 3 minutes. It sounded like a jet engine. Literally 50& of my printing simply didn't go through. Most days, rebooting was the only trick for waking it up.

Check out the distribution of the reviews---positive to negative. see anything else that looks so bad?
This is a seriously flawed product in virtually every way.

Don't buy if you use a Mac.  Failing on all fronts.  It may work, but I haven't been able to confirm after a couple hours trying.

I would not recommend this printer. After a couple hundred prints, the paper cartridge began to fail. It can no longer reliably grab and feed sheets (I am using pristine, high-quality laser paper) I can now get it to work half of the time, only by precariously tipping the machine back at a 30-degree angle allowing gravity to help the grabber.

Moreover, the color is much too dark, and only Windows users have access to color management in the driver software. The Mac driver offers only bare-bones options. There are other comparably priced color-printers out there that are far superior quality, reliability, and better-supported for Mac.

Logitech falls down. Because Logitech no longer supports the Logitech Control Center on OS X, they really should not advertise these mice as Mac Compatible. What you end up with is a generic three-button mouse configurable only through the basic Mouse control panel that is built into OS X. This is a huge disappointment. Logitech used to be my only choice when looking for a new mouse. I will be avoiding Logitech products from now on.

The lack of support from Logitech is exacerbated by the technical failings of the mouse; it tracks so poorly as to be almost useless. The cursor skips, sticks, and jumps almost continuously. What a horrible mouse.

Get a hamberger helper instead.  This feels cheaper than easy mac.

Don't believe the hype that this item is Mac compatable. After carefully following the mfr's installation and operation instructions to the letter,  the item suddenly  disappeared from the desktop. It won't mount  on MacOS 10.3.5 nor on MacOS 9.2.2. Nor will it be recognized by the Disk Utilities included with these MacOSs and Symmantec/Norton SystemWorks. This external drive is a ripoff and an unreliable piece of junk.

The Passport crashed with app. 2,000 backup pictures. The device cannot be reformatted with iMac's disk utility and the procedure for making a warranty claim is insane. In other word, I am out $100 on a device that is less than 5 months old. Don't buy.

Bought this printer to use with a Mac. Product description says it's Mac compatible. Printer arrived with a driver CD for Windows but not Mac. Dell website shows a Mac driver but the link is broken.

When I used the "chat" function with customer support they asked for my email and phone number twice, then told me "because you purchased this online, you will need to fill out an ownership transfer form."

After I told the agent I was interested in drivers for both 10.6 (Snow Leopard) and 10.7 (Lion), the agent replied:"The Lion OS is not supported at this time, however there is an update through the MAC software update from Lexmark for generic drivers for the Lion OS. For the Snow Leopard OS, the website is currently being updated I will be happy to get your email and send you the link once the website is fully updated."

After a few more back and forths during which I was asked for my email address yet again, the rep told me she would email me the driver link once it became available. I'm not holding my breath.

Big waste of time.

If I could enter a 0 for number of stars I would do so.

Update

I badgered Dell on Twitter and they got in touch with me and provided a link to a working driver. I think the issue is that someone else makes this printer for them and they got their wires crossed. The machine is now working fine and I've upgraded my review from 1 star to 3.

Update: They told me it would work with the new El Capitan but it freezes. I have to swipe to another screen and back to close each open window. Less than a year and they want you to upgrade.

--------------------------------------------------------------------
I bought a MacBook Pro a little over a year ago because of Parallels. I had thousands of dollars worth of Windows applications that I did not want to just toss out. And it's been so cool to literally swipe between Mac and Windows. And it was working just fine for the most part. Then I came across the download for the latest update and followed the instructions which led to disaster!

The install went great until it popped up a screen that said you MUST register to run Parallels. There was nothing mentioned in the instructions about this. I was led to believe since I only had been using it about a year this was your typical upgrade. Worse I could not get into my Windows applications which is where I store a lot of information including logging into the Parallels account! I tried the forgot password link but never received the email from them. I called tech support and waited almost an hour when the idiot gets on he doesn't turn on his headset so all I hear is hello several times than he hangs up!

Fortunately I'm smart enough to make data backups and dug out my login info. And I paid the $50 for the upgrade. I understand the need to purchase new versions - Microsoft, Adobe, everyone else makes you do it. But the way they forced me into it really pissed me off especially locking me out of my system - that's like ransom and should be illegal! And I can't find the free tools they said came with the new version!

I still love the fact that I can literally swipe between Mac and Windows even though I use Mac more and more all the time. If Access and Visual Studio were available for the Mac I would probably dump Windows altogether.

I have had a couple times in the past where tech support worked very well. So it looks like whoever has taken over has resorted to scum techniques - no support and tricking you into buying upgrades. I love the application so I hope the company gets its act together!
