Works well but sometimes fights with my IMac
928464
I have a late model 27 inch IMac and I use this device to host 3 external drives as well as a blue ray player and a scanner.  The unit works great with the external drives but I have had some difficulties with the other devices.  After a period of time, usually overnight, the computer "forgets" those two devices. I have found that by unplugging the usb cables (on the scanner and blue ray drive) and then re-plugging them in, enables my computer to reinstall them correctly.  It's only a minor inconvenience now, but it took a while to figure out.

It keeps timing out--whether or not it is connected to my iMac. I would like the latest system on it.

Works fine, but I had a big hassle getting it to scan to my Macs.  Brother manual, Brother on-line and Brother e-mail help were no help with this.  I had to find the simple solution on my own.  With that behind me, I may buy another.  Buyers should note that it won't work with Mac OS's prior to 10.7 so I have one 10.6.8 for which I have to use an older printer while this one does nicely with our OS 10.10 (Yosemite) Macs.

My main computer is a mid-2011 iMac.  I have an iPhone 6 and I recently purchased an iPad Pro 12.9".

For me, the problem was simple - I want to charge my devices at night, when I'm sleeping.  However, I also want my iMac to sleep when I'm not using it.  Putting the iMac to sleep cuts power to the USB ports, preventing my devices from charging.  If I use the wall blocks, my devices don't sync.  There is nothing more annoying that trying to show a friend a picture or listen to a CD I recently imported, only to realize I hadn't synced my device in several days and it wasn't there.

I've tried iTunes Wifi Sync but my iMac is connected via ethernet, so I found it to be extremely unreliable.  I tried iCloud Photos but with several GBs of pics and videos, I found it to be flaky as well.  I also added the iPad Pro, which won't even charge from my iMac because the ports are USB 2.0 and don't supply enough amperage.

This hub solves my issues perfectly.  When I plug my devices in at night, they sync and then I put my iMac to sleep.  The devices continue to charge all night due to the fact that the hub has it's own power.  When I wake my iMac up in the morning, they sync again automatically, so I'm now syncing my devices twice a day, without fail, in addition to making sure they're always charged.  Secondarily, it makes my USB ports much more accessible, since the iMac only has USB ports on the back (and under the keyboard if you use the stock Apple USB keyboard).

As for specifics, I first want to say that this device DOES provide enough amperage to charge my power-hungry iPad Pro.  The factory Apple wall block is a 12W (5.2V / 2.4A) charger, which is capable of charging the iPad no matter what I'm doing, even playing games.  When plugged into the Plugable USB 3.0 hub and in use (with the iMac on), my iPad charges at about 1% every 9-10 minutes.  Yes, it's slow but it does charge.  With the iMac asleep and the iPad not in use, it charges adequately for my needs, meaning it charges to 100% in 5-6 hours while I'm sleeping.  I have not tested to see EXACTLY how long charging takes with both the iMac and iPad asleep since that does not really matter to me at this point.  It also charges the iPhone 6 quite fast and charges the iPhone without issues even when the iPad is also in use and charging.

I have seen some reviewers admonish Plugable for incorrectly advertising the power output of this device - their math is correct.  The 60W power supply would only be adequate for powering 5 of the ports at the full 2.4A, not all 7.  However, I just can't see powering all ports at 2.4A to be a realistic use case and thus I'm not deducting from review score because of it.  If you truly have 7 iPad Pro's that all need to charge at the same time, it's fairly obvious to me a little device like this probably wouldn't be the right solution. If however, you have a couple of smartphones (most of which pull 2.1A, not 2.4A), a tablet, and some USB thumb drives, this little box works great.

I got this last week to use with my iMac. It works perfectly, easily and has had no issues so far.
Time will tell if it holds up - as the DVD tray seems kind of cheaply made, but overall so far... no complaints.

I bought this to use with my Macbook Pro 13" (mid 2013). It is very easy to setup and use. However, I don't like that uses one of my USB ports (obviously I knew this from the beginning) and if I plug something into the other USB port, I often have keyboard issues. I regularly plug something into the other port-- an external hard drive, my iPhone, etc. The mouse will often get very slow and jumpy. If I unplug the other device, or move to the built in keyboard and track pad, the issue stops immediately. I've thought about buying a USB hub to plug all of my peripherals, but it might be money better spent by just buying a new keyboard and mouse.

Still trying to learn how to use this device with my Imac computer; but works very well for inputting sreaming data and sound output.

Paired well with my iMac, good data storage for the price

I bought this to transfer photos from my Canon EOS Digital camera after I upgraded my 2012 mac (with USB 3.0) to Mountain Lion (EOS Utility no longer works).  Compared to plugging the USB cable between the camera and my old USB 2.0 computer, this was noticably slower.  I don't see any evidence of USB 3.0 speed on this unit.  However, the insertion of this device triggered the Canon CameraWindow application (apparently that one still works in Mountain Lion) and downloaded the photos into date-separated folders, similar to the behavior of the EOS utility.  It is possible that the transfer speed is related to the Canon software, rather than with the unit itself.  As other reviewers have mentioned, the width of this unit blocks access to other USB ports (and the thunderbolt port, unless it's mounted in the USB port furthest away), but this could be easily solved with a USB extension cable if it was an issue.

Bottom Line:  Works well, but not at USB 3.0 speeds

This does exactly what it's supposed to do and because of that there are some quirks you have to work around. For me the biggest "quirk", and the only one I wasn't expecting, is the inability to place the OS X Dock in one corner or the other. This was possible prior to OS X Yosemite, but Apple made a change with Yosemite (and continued it in El Capitan) that no longer allows you to pin the dock to a corner. This means if you prefer the dock on the bottom of the screen, it's going to be split across two monitors, and not in an atheistically pleasing way. Another similar issue comes with running apps full screen. Like the Dock, full screen apps will be split across the two screens. So if you try to make a video full screen, half of the video will be on one monitor, half on the other. There are a couple of other minor issues due to the screen splitting, but for me those are the only two of any real consequence.

Setup on my Mac was not entirely self explanatory but it works great now that it is setup. Moved Photos there and it performs the same as it did when on the main hdd. I do not notice any latency issues when using photos. Moving iTunes next.

All in all a well designed product, performs well, however does have some issues.

Have issues with intermittent problems with iMac (intel, OS X 10.5).  Need to periodically unplug from iMac, reboot and then reconnect.  Intermittently causes extremely long boot issues.  Have isolated issue to USB Hub itself.  Have two and they both suffer from same problem.

Am looking for a more Mac stable solution.

No noted issues yet when used with Windows.

Works fine with my iMac.  I bought it as a cheap replacement for the Apple Magic Mouse which broke.  It does not reconnect as fast as the Apple mouse (this one takes a few seconds to reconnect where the Apple mouse was instantaneous as far as I could tell) but otherwise it works great.

This product works for my Mac and TV, but it need to be shoved in all the way and if moved slightly it will loose connection. Although it could be my Mac port...

It disconnects randomly from OSX... especially when the iMac wakes up from sleep. This hub is still asleep on the job. Had to push the power button off and on to wake it up.  Very irritating.

Its good.. doesn't work as well with apple as it claims.. my mouse started freezing when using this one so i connected it back to main module.
