The iMac is a great desktop workstation with a brilliant monitor, powerful processors and high-bandwidth connectivity. And it comes with an array of ports for connecting peripherals. But these ports are positioned at the rear side which, at times, makes it hard to reach them.
Insert the SD card for a quick upload of your latest pics? Connect a USB flash or an external HDD/SSD to duplicate some data? Charge your iPhone? The all-new LMP Attach Hub brings the most needed ports to the front side, making it easy to access them at all times. It even multiplies the USB 3.0 ports (3x) and adds a microSD card reader. And by using two connections to the iMac (one Thunderbolt 3 (USB-C) and one USB 3.0), the USB ports have plenty of power to charge even an iPad or run two 2.5″ HDD/SSD at the same time.
The LMP Attach Hub is mounted to the iMac’s vent holes in a few seconds thanks to its patented mounting spring mechanism. It’s ready to go in less than a minute and is highly functional yet only interfering minimally with the iMac’s appearance.
Works with 21.5″ iMac and 27″ iMac/iMac Pro with Thunderbolt 3 (USB-C) ports. It requires one free Thunderbolt 3 (USB-C) and one free USB 3.0 port.
Yes, it can be used for older iMac as well (i.e. with Thunderbolt 2 ports) and all ports will work.
However, you must use a USB-C (f) to USB-A (m) adapter to attach the USB-C cable to a USB 3.0 port of your iMac.
It is normal that any USB-C hub or dock becomes hot when attached to the laptop. The aluminum housing is meant to dissipate the heat from the inside to the environment. There is a number of chipsets working on the inside which are producing some heat since they are constantly in a stand-by position to react quickly should any port be used. The surface temperature is well within the allowed limits and reaches about 40° C in stand-by mode, 43° C under normal use and a max. of 48° C when all ports are in full use, CPU load at 100% and PD attached. The heat does neither pose a danger to the laptop or any attached device, nor does it influence the USB-C hub’s/dock’s performance or even shorten the life-span.
Furthermore, the surface appears to be hotter than it actually is since it is touched with the very senstive fingertips. We suggest to remove the USB-C hub/dock when not needed in order not to emitt unnecessary heat to the environment and not to use any energy.
Basically, you can use only the iMac (27-inch, Late 2009) and iMac (27-inch, Mid 2010) with a Mini-DisplayPort connection with the current Mac with Thunderbolt 3 (USB-C) ports. You need a USB-C to Mini-DisplayPort adapter (e.g. 16134/16138, LMP USB-C to Mini-DisplayPort adapter) or a USB-C dock with Mini-DisplayPort port (e.g. 18641/18645/19009, LMP USB-C Travel Dock 4K 9 Port or 17113/17278/18954, LMP USB-C Compact Dock 4K 8 Port or 17116, LMP USB-C Display Dock 4K 10 Port). Then a Mini-DisplayPort to Mini-DisplayPort cable (8305, LMP Mini-DisplayPort to Mini-DisplayPort cable) must be attached to the dock and the iMac.
With iMac (Mid 2011 to Mid 2014), it is possible to use the iMac as monitor with a Thunderbolt connection only. With a newer iMac, a Target Mode with an iMac is not possible anymore.
