Here's a fairly detailed write up I did a while back for someone looking for something similar to what you want, recommending the "Anne Pro":https://hardwarerecs.stackexchange.com/a/7633/6475I'll go through your list to address your needs specifically:Brown Switches YesMac Keys - Yes. The board has four layout profiles; one of them is dedicated for Mac and the other is fully customize-able including Mac key functions. The keyboard comes with Windows printed keycaps but they are standard size so finding keycaps with the Mac print on them should be easy enough.Construction - This category is a mixed bag with the Anne. It's plate mounted, has quality keycaps, and feels / sounds sturdy despite the plastic housing. I will say the stabilizers can be a little rattly out of the box, mine was enough that I spent maybe 3-5 hours finding and performing modifications to resolve the issue. I'll be happy to provide more info on my specific mods if you'd like, but it was less than $10 in materials and I'm very happy with the result. So it's not perfect but it's certainly something you can work with.Driver - There isn't an app or anything but Anne Pro works out of the box with MacOS. There are apps for Windows 7/8/10, Android, and iOS that you can use to customize the lighting and key layout.Numpad - No dice, this is a 60% board so it does not feature a numpad or dedicated arrow keys. I have my Fn button set to the CAPS LOCK key, and arrows bound to the function layer at WASD and IJKL, this layout works extremely well. Yes I miss the numpad, I will likely end up buying or building a mechanical one to pair with the Anne Pro at some point.Programmable RGB - Yes. There are a few dynamic light modes as well. Programmable RGB layouts are only possible as a static layout, you can't currently make custom dynamic layouts (though this feature is supposedly coming with the 1.5 firmware promised over a year ago, sooooo yea). The only other thing about the firmware that blows is that the on-board macros don't work, but I assume you can live without that since you didn't list it in your post.USB hub - The Anne doesn't have one of these unfortunately.So it's got just about everything aside from the numpad and the USB hub. Amazon usually has them for $60. It may cost you an extra $5-10 and a half a Saturday morning to get it where you want it, but you might be really happy with it right out of the box too. I'd recommend reading the answer I linked as it addresses some aspects of the board that weren't listed in your post in greater detail. There's also a dedicated community on reddit for this keyboard, so you can swing by over there to get a feel for common problems / solutions and popular modifications.If you have other questions about this board feel free to ask and I'll edit in my responses. Best of luck with the search!.• Related QuestionsBearded dragon info please!?Bearded dragons can be housed in a variety of enclosures as long as their basic requirements are met. All glass aquaria with wire tops are commonly used and are inexpensive to obtain. Custom built enclosures are also very popular and can be sized appropriately. The enclosure should have a basking spot with temperatures ranging from 90 to 105 degrees Fahrenheit, which can be provided by an overhead light in a reflective hood. Under tank heating can be used for night time use, supplied by a heating pad or tape. The enclosure should be large enough to allow the lizard to retreat to a cooler area (known as thermoregulation) as needed. A tree branch or log should be supplied for climbing and basking. Good substrates are newspaper, sand, pea rock or aquarium gravel. Substrates such as mulch, shredded tree bark, or corn cob should not be used as they can hold moisture and promote bacterial growth. Bearded dragons should be offered a varied diet consisting of crickets, mealworms, pink or fuzzy mice and a variety of greens and vegetables. Juvenile animals can be raised on small crickets and greens until large enough to eat mealworms and mice. It is very important to regulate the size cricket given to juvenile dragons. Large meals have been associated with partial paralysis and hind leg extension. A general rule is to use crickets no larger than the distance between the dragons eyes to the tip of his nose, and should be offered in several small meals per day rather than one large one. Crickets should be dusted with a vitamin/mineral supplement every other day for up to three months, then reducing supplementation to twice a week. Fresh greens, such as collards, kale, and mustard greens should be finely chopped and offered every other day along with vegetables such as yellow squash, zucchini and shredded carrots. Be sure to thoroughly wash all greens and vegetables before offering them to your dragon. Bearded dragons in the wild get their water from the morning dew on plants and afternoon rains. In captivity, they seem to have a difficult time recognizing standing water. A simple means of offering water is to spray them at least once or twice a day with a spray mist bottle. They will lap up the water off of their noses and lower their head to standing puddles if some type of movement is detected. Bearded dragons (if kept indoors) will require full spectrum lighting with UV-B and UV-A, which helps in synthesizing vitamin D-3 which is required for calcium absorption. These bulbs can be purchased from Zoo-med (Reptisun 5.0) and are relatively inexpensive. Vitamin/mineral supplements which contain vitamin D-3 should be used to dust crickets and/or greens to ensure proper calcium absorption for bone development in growing dragons. Bearded dragons which are kept outdoors or are allowed at least 30 minutes of natural sunlight every other day will not require any special lighting as long as a basking spot with an incandescent bulb is supplied. Newly acquired bearded dragons should be allowed to get acclimated to their new enclosures and feeding schedules before attempting to handle them. Once acclimated, short periods of handling and hand feeding will quickly tame most dragons. They will be content to sit on a shoulder or lap for hours while watching TV or using the computer. Young children should be supervised and instructed on careful handling techniques. Be sure to wash your hands before eating or smoking after handling any reptile. practically everything you need to know :)
