Microsoft Office for Mac 2011... Home and Business version (Single Copy ONLY... picture is of three copies)This comes with ONLY the DVD and individual key code on the back of the disc sleeve. No documentation is included.These were used on Macintosh laptops for a local county District Attorney's office. I spoke with the IT Manager and he said they simply loaded them on the computers when they first came in and then did not use them for upgrade purposes after that... so you are free to do that if you wish. These were NOT part of a bulk license agreement with Microsoft... each has its own individual key code.There is a volume discount for buying multiple sets PLUS Shipping is a Flat Rate... $3.95 for shipping the first copy that you buy and nothing additional for any additional sets.UPDATE: So far I have sold about 40 of these to buyers. Most are having success with it and leaving me positive messages and/or response. But about five buyers have failed to check to see whether it is compatible with their computer's operating system before buying. Let me be clear... it is now 2024... and this is MS Office 2011. Whether you buy this 13-year old software from me or someone else on (or in a store if that is still possible) it is up to YOU to make sure that it is compatible with YOUR computer and operating system. This is a great solution for some Macintosh owners who don't want to pay Microsoft full price each year.. but like all software, it doesn't work with all Macs. I don't personally use Macintosh so I have little knowledge about this software's compatibility... but here is what Wikipedia says if this will help you..."As 32-bit software, it will not run on macOS Catalina or later versions of macOS." According to a different Wikipedia page the macOS Catalina came out in the fall of 2018.
